Are the Big Oil Companies suppressing the truth?

Ask yourself, who is really running the war?
Who is making a profit on the war?
Who has suppressed alternative energy, or made the cost out of reach?

Folks This is 2007, and with the advancing science technologies, something other than oil has to be out there. Plus why is the cost of a solar panel,Fluorescent lamps, and wind generators so expensive.

Thomas asks…

Many universe hypothesis vs Single universe hypothesis?

I have been reviewing and reviewing, but I can’t quite seem to understand. How does the atheistic many universe hypothesis initially appear to have an advantage over the atheistic single universe hypothesis when answering Collins’ fine tuning argument? And how is there ultimately no such advantage for the atheistic many-universe hypothesis because of the fine-tuning of its universe generator?
Thank you so much in advance

admin answers:

For those not familiar with the concept:

“Intelligent Design” proponents see the universe as “fine tuned” for life in general and us in particular.
The universal constants of gravity and electromagnetism and the strong and weak nuclear forces are such that after the “big bang” event, stars could form, and they could “cook” complex elements which were then blown out into the void when these stars went nova…. To re-form as 2nd and 3rd generation Suns like our own with complex rocky planets capable of supporting life.

They point out that (according to their reckoning) the chances of the universe falling out with exactly these constants is very small, and that the fact that it is as it is indicates design…..

Cosmologists (and mere critical thinkers like myself) point out that there is no reason to think that this is the only universe. Cosmologists propose any number of scenarios where there might be essentially an infinite number of universes, and that new ones are being formed all the time.
If this is the case, it’s merely lucky for us that this particular one happens to be amenable to the formation of life; there might be any number of universes which would have characteristics so alien as to be incapable of supporting life.

Although there is no evidence of such other universes, there is no contraindication of any as well. We could never observe them, our ability to observe being confined to our own universe.

Besides, it’s a rather silly notion, IMO. Even if we locally have a solar system and a planet capable of supporting life, obviously these conditions are very rare in the universe… Billions of stars with no planets, billions of planets that are nothing but frozen balls of ice or masses of gas…. Or rocky chunks with no atmosphere or water.
Why would a “designer” put together such a vast and empty universe just to support…Us?

Ken asks…

Cheap residential hydrogen fuel cells (where can i get some)?

Anyone know where i can get a hyrogen fuel cell that is designed to generate 240v ? I was thinking of hooking one up to a windmill to make free lighting for my house. Anyone know the cheapest and best u.k distributers, or any other worthwhile info on this subject, thanks
Just for the record, it looks as so some of you have your heads up your arse. A fuel cell does not run on thin air, it needs some power input of one sort or another, hence the windnill.

admin answers:

Unfortanty because it’s a new type of business, everything is expensive. Solar cells will take about 10 years to pay for it’self, wind I belive is 7, and hydrogen (the ones you put water in and it generates power and of course oxygen are the most expensive.

But for that hydrogen he’s a website below.

The small house windmill, according to where you live, = how much energy it will produce (it’s size) and your own uses, you can sale some to the grid, but this is so new (alt power) they can’t give you a diffanate – so don’t belive the salesman, no one really knows so what would make anybody think they actually know.

The 2nd lnk below is what I personaaly be the best method so far, in the fiels of Alt power. Thing is it’s new, and so you will have to follow his work, at Davis Univ, but the money they bring in goes to get the generators on the market – its cheaper than all of the other types I mentioned above = it mimics the way plants and water get its energy from the sun, to produce energy.

Your Questions About Solar Energy Materials And Solar Cells

Mandy asks…

In simple terms, how would you describe what goes on in a solar cell in solar energy?

I have a science project and I have to expalin to the judge what happends during the process of solar energy. Can you please summurize it in simple, easy to remember terms?

admin answers:

Basically what goes on in a solar cell is the conversion of light energy (photons) to electrical current (the flow of electrons).

In physics this is called the photoelectric effect.

A solar cell will absorb light energy (the photons, which could be visible light, UV light or IR light generally), and this light energy will energize electrons in the atoms of the cell.

These electrons will cause a charge separation (positive and negative) in the material (a voltage) which will have a mechanism for trapping the electrons to maintain the voltage.

Current will then flow if you connect the separate charged ends of the cell with a conductive material.

I am not sure how to make it simpler…

Mark asks…

What type of solar cell is the Cuprous Oxide-Copper cell? Can you tell me how it works?

On, a solar cell made from Cuprous Oxide and Copper is described, but the explanation is made for a middle-schooler. I keep researching how how the solar cell would work but can’t get a explanation good enough for a high-school level science exposition. thanx in advance.

admin answers:

The cell works the same as a silicon wafer or any other solar cell.

When photons strike the surface, an electron in the Cu(II) oxide plate is promoted to a higher electronic state in the conduction band,

Being attached to free Cu, electrons in thier conduction band allows the electrons mobility and flow as current when there is a circuit load. Drawing off this current leaves holes n the Cu conduction band.

See. Electrons in the atoms of each material reside in bands, much like the floors in a “two story” building with a flat roof. When light strikes the electrons, they gain energy and are promoted to the roof, where they can move around (conduction) . Siphoning off these electrons (electrical load) leaves more room on the roof, for more electrons to be promoted from below.

Helen asks…

how to install a generator on elliptical?

I want to try to install a generator on my elliptical but I don’t know how to search for instructions on how to do that. After doing that I’d like to convert it to dc power and then store it in a battery from which I could charge portable devices or do something with it….why waste good energy.?

anyone know where I could find a good tutorial on creating your own for an elliptical?

admin answers:

I would start by studying the elliptical. I would guess it uses an AC induction motor with a variable speed drive. If so, you would need to replace the AC motor with a DC generator using the same mount, and also get it to accept the gear or pulley that was used by the old motor. The battery might need a “charge controller” such as might be used on a PV solar system.

David asks…

How can i keep my RV cool in the summer?

What are some effective and efficient ways to keep my RV from getting too hot in the summer? I have an air conditioner, but I don’t have a generator, so i’m looking for ways to keep cool without electricity. At most maybe a box fan. The only thing I have found so far, for example, is KOOL SEAL roof coating which says reflects the sun’s rays and cools the RV by up to 35%. Any other ideas, like where to position the fan, what windows and vents to have open, etc.

admin answers:

Kool seal’s a great idea. Go solar, two panels on the roof will power fans to blow the hot air out. Park so that you get the afternoon shade on the side of the rv that does not have the roll out canopy and of course roll out the canopy you have, if not get one. Avoid cooking with the stove inside get a portable to use outside with an extension to your outside propane tank. Add insulation, sometimes an older rig was remodeled and insulation was removed due to water damage. There’s also small portable swamp coolers that use way less electricity then an ac unit and could run on solar power get one of those. If your hooked up to water get the water misters that hook up to a hose and put those near windows that the breeze can blow through. Finally when you just get too hot role down the window and move on to a cooler place that’s why “that there is an RV Clark”, you can take your home and roam.

Chris asks…

Essential Services and the Economic Crisis?

With this economic crisis looming over all of our heads. There have been people from all walks of life finding themselves losing there jobs and income and the flow on effect is they lose therefore there livelihoods.
To avoid this from happening to myself i have come to the conclusion that getting into a job that is part of the essential services such as Fire, Police, Paramedics are the obvious but i am looking more attainable such as Energy, Food, Waste industries.

My question is what sort of jobs out there could one get into that would be in a position to ride out this economic crisis

admin answers:

Internet sales. Supplemental income or full time. Worldwide exposure of your product.

There’s also good money in saving people money. If you can offer a product or service that saves people money, you’re doing well right now.

This is however a double edge answer.

I think the thing to be thinking about is how fragile our livelihoods are. Think about it. If you lost your job today, how long could you live in your current home without any income?

We need to be smarter with our purchases, save our money, invest in items that can help us sustain in any crisis like solar heaters and electric panels, wind generators. Stop living outside our means.

The problem is everyone is flocking to “essential services”, but even the police have suffered budget cuts. We need to be able to maintain in times like this, be better prepared.

We all need to make our own individual financial foundation stronger. A tomato plant with a weak stem won’t be able to produce much fruit…especially in a drought.

Earth4Energy questions, how long and how cheap?

I might be looking into buying that kit, and im wondering like what is the cheapest easiest first porject it shows you how to do, and for how much?

and how long does that first project take?

and how long do the other project approximately take and for how much $?

thank you very much

admin answers:

Eath4Energy is a scam. Please see my review at

If your motivation is to reduce your energy bills, then you should first look at conservation projects. These are things like using low flow shower heads, replacing old appliances and adding more insulation.

If your motivation is to generate some energy for learning purposes or as a matter of principle, then consider the following:

Building a wind generator yourself is not a simple project. If you can build an utility trailer for your truck (welding, metal fabrication) then you could certainly tackle the job. There is a great book available from called Homebrew Wind Power plus you can order any parts and assemblies that are beyond your abilities to fabricate. Cost of turbine is about $2000 and you need a tower as well. There are cheap units at some hardware stores but they are garbage compared to to the unit designed by

A more realistic project would be to get a commercial solar panel (making your own from broken cells on eBay is not worth it), inverter, charge controller and battery and using it to power some things in your house. For about $1000 you could have something to power a small computer. A complete system to power your home is more in the $30,000 range.

There are, unfortunately, no cheap ways to make your own power as Earth4Energy is promoting other than perhaps getting lucky in an eBay auction or purchasing a solar system from a bankruptcy sale.

Do your conservation measures first. Then read Homebrew Wind Power, read the solar links at and then decide what type of project you are up for. By then, you will know exactly what you want to do.

Your Questions About Solar Energy

Donna asks…

What do the batteries to store solar energy contain?

I am told batteries for storing solar energy contain cadmium and small amouts of mercury. Is this true? what else do they contain?

admin answers:

These are your best bet for solar energy batteries, most are just simple car batteries. If you think about it, all is required is that they store electricity. The battery doesn’t know where you generate it from so I have complied a list of batteries you could use for storing solar electricity (bear in mind you will need around 5 of these for it to it be worth your time)

Your choice of solar batteries breaks down into these six groups:

Golf cart batteries – These are relatively cheap but will only last 2-6 years

Regular deep cycle batteries – Reasonably priced and will last 4-8 years

Premium or “heavy-duty” deep cycle batteries – The extra pounds will get you a lifespan of 7-15 years

Sealed gel cell batteries – Cheaper than AGM batteries but will only last 2-5 years

Sealed AGM batteries -Will last 4-7 years with little maintenance

Industrial batteries (e.g. Forklift) – These workhorses can last 10-20 years

I know all of this because I work for a Solar Photovoltaic installer and I know just about everything there is to know about them as I have the responsibility of sourcing, ordering & installing the panels!

Hope this helps!


Mark asks…

What other types of energy can solar energy be converted into?

Besides thermal and electrical energy, what can solar energy be converted into? Please post your reference if you have one.

admin answers:

Energy from the sun comes in the form of heat and light. Plants convert light into biological energy through photosynthesis.

Photovoltaic cells and panels convert light to electric current. Heat from the sun can also be converted into mechanical and electrical energy by focusing the heat on a steam generator to run a steam engine or hot air engine.

Mechanical energy can be further converted into electricity, and electricity can be converted into mechanical or chemical energy.

You can easily develop your own bibliography on this topic. The internet is slam full of information uses for solar energy.

Good luck!

Your Questions About Solar Generators For The Home

Nancy asks…

Electric start generators…Is it possible to charge the starter battery while it’s running?

Electric start generators…Is it possible to charge the starter battery while it’s running using it’s self generated electricity? Or is there some kind of solar charger that would work?

I just need a small generator to use this fall at my farm. There is no electricity there and because of physical problems, it would be impossible for me to bring it home for charging.

admin answers:

ALL the electric start generators I have seen have a BUILT IN charging circuit for the starting battery.

Note that the MAJORITY of smaller electric start generators NOT designated as “standby generators”or LESS than 10,000 watts capacity have batteries that can NOT start them reliably IF the weather is below freezing, so plan on using a “jump” from your vehicle battery in winter.

Betty asks…

Would solar panels and a wind turbine make enough electricity a day for one house?

A well insulated home which is an average family home.

admin answers:

First determine your demand: ____kwh per year (check your power bills for last year). Typically, a household uses about 14,000 kwh per year. My family uses about 8500 kwh per year.

Then, consider your solar-power and wind-power potential (see links) To supply 14,000 kwh you would need a 5 kw solar panel system (depending on your solar-day potential), or a couple of 3 kw wind turbines (again, depending on your wind-power potential), or a combination of the two. A house in windy desert southwest would have a good chance of getting enough power from the sky. However, a cabin in the pines of the Northwest or Northeast would not.

Next, you would need a storage system (batteries), and accompanying control and distribution equipment, unless you want (and your utility company agrees) to tie your system into the grid.

Finally, if you want to be independent, you would need a back-up system (gas-powered generator) in case of lack of sun or wind, or during times of repairs and maintenance on the solar and wind components. This would need to be about a 3 kw generator if it could be used with storage system batteries, or larger (depending on your demand) if it must be used solo.

Michael asks…

How does energy work under the dark or the rain if the house is solar powered?

Solar powers work under the sun, right?

admin answers:

You are correct. Solar power works under sunlight.
Most solar systems have some sort of power backup.
In remote locations that are “Off Grid” or where maintaining constant power is critical, this is often done with a bank of battery and even a diesel generator as backups.
If traditional power is available, then most opt to use their solar to augment the power from the utility company. A common term is “Net Zero”. When you generate more electricity than you use the electric meter spins backwards. This happens during the day when the sun is out and no one is home. Then at night and cloudy days, the meter spins normally. So the readout spins back and forth. At the end of a period of time you get billed on the net difference. You want the net to be zero. The goal is to produce just what you use. Any less and you have to pay for electricity, any more and you are giving it away.

It was 5% in 2007 so yes about 6%. Someone in the gov. Ought to have a word with the planners, they are stuck in the 19th century. Whilre they were at it they could find out why we are still paying 17 1/2 % vat (luxury level!) for solar panels, wind turbines, insulation even. Outrageous.

The big idea is offshore wind, but shell just pulled funding for the big one planned off east coast (dogger bank) and the gov. Dont seem keen to put anything up for it.

Microgeneration would be a big part of reaching the target, but that would makke us less dependant on the big comanies and the national grid….. Oh maybe the vat thing (and lack of grants) makes sense….

Michael asks…

the disadvantages of windmills and disadvantages of solar energy.?

hey i’m doing a debate in my high school science class and its about alternative energy. my group is doing wind energy and there aren’t really that many disadvantages that i could find. one disadvantage was that it kills hundreds of birds. what point should i back it up with if the opposing team mentions it? also what are some good points that i can through at the opposing team? their doing solar panels/solar energy.

admin answers:

Where did you get the idea that wind mills kill birds ? Not so, the trouble is that you youngsters are told stories like the killing of birds.Fact is they are not used enough, China has more wind farms and enough to power a very large industrial city out in the no mans land of China. This country tells you kids what they want you to buy into, called” wagging the dog ” dis-information, just look at the oil spill. We we’re told that the leak was pouring out at approx 5 thousand gallons- reality was that it was sending more then five times this amount.
So in the long run the only disadvantage is that they’re not enough wind farms in use, so you do some more in-depth searching on wind farms and this will get you a winning team to work.

Robert asks…

how to build a model solar generator?

I need to make a model of solar generator for my project. so please someone help me to build it.

admin answers:

You could make a Stirling engine from a kit and use solar heat to run it. Google for Stirling engine kits. In addition to the engine itself, you’ll need to come up with a way of producing enough solar generated heat to warm up hot side of the Stirling engine. Pointing it towards the sun might be good enough, but if that doesn’t work you might try making a reflector to focus sunlight onto it.

You could also use a solar panel. Making a solar panel yourself is difficult, because they’re made out of silicon wafers in cleanrooms, but you might be able to get an internship at a fabrication lab if you want to make solar panels.

Chris asks…

How can I make a cheap portable solar powered generator?

I need to know about the parts needed to make a solar power generator and also the instruction on how to make it?

admin answers:


Using parts easily available from your local stores, you can make a small solar power generator for $250 to $300. Great for power failures and life outside the power grid. Power your computer, modem, vcr, tv, cameras, lights, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise. I keep mine in my bedroom where it powers my cd player, turntable, lights, modem, laptop, and (ahem) a back massager. I run a line out the window to an 8″ x 24″ panel on the roof.

1. Buy yourself a small solar panel. For about $100 you should be able to get one rated at 12 volts or better (look for 16 volts) at an RV or marine supplies store.

2. Buy yourself a battery. Get any size deep cycle 12 volt lead/acid or gel battery. You need the deep cycle battery for continuous use. The kind in your car is a cranking battery–just for starting an engine. Look for bargains, it should cost about $50-60.

3. Get a battery box to put it in for $10. (This is good for covering up the exposed terminals in case there are children about If you going to install the system in a pump shed, cabin, or boat, skip this.)

3. Buy a 12 volt DC meter. Radio Shack has them for about $25.

4. Buy a DC input. I like the triple inlet model which you can find at a car parts store in the cigarette lighter parts section for about $10. This is enough to power DC appliances, and there are many commercially available, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.

5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. I bought a 115 volt 140 watt inverter made by Power-to-Go at Pep Boys for $50. More powerful inverters are available by mail. Count up the number of watts you’ll be using (e.g., a small color television(=60 watts) with a VCR(=22 watts), you’ll need 82 watts).

6. Use a drill to attach the meter and DC input to the top of the box.

7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way

8. Close the lid (I use a bungee cord to keep it tight). Put the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.
Options: A pop-up circuit breaker may be added between the positive treminal and the volt meter. Some of you will want an ampmeter as well. The panels I recommend have built-in bypass diodes, but I recommend charge controllers for people who have panels without diodes. Another option is a voltage regulator, which is not necessary for a system this small, but a larger system would require one.

William asks…

What is the best electricity generator for my scenario?

I have a 800 square foot cabin in Maine. I want to get electricity out there to power a t.v., radio maybe, MAYBE a computer, a room fan, basic lights, washer and dryer. Im wondering if I should use solar? Wind? there is a stream running nearby and Im curious about “Micro hydro turbines” to fuel my electricty. Im just looking to see which is best for the money, and electric output. – Thank you

admin answers:

A fuel powered combustion generator is most cost efficient. You can get gasoline powered generators for under $150 per 1000W, which would do that.

Solar and/or a small wind turbine would be next up. You would need a battery set to store the charge, and an inverter to power your AC loads. Your computer, TV, and radio could be set up to work off of battery directly, if you choose the right ones.

Unless you are going to build a dam an all that, collecting energy from flowing water is not economical.

In any case, get a propane stove and dry your clothes on a line. You should get a tri-fuel fridge, if not a 12/120V one.

Susan asks…

details on how different types of power is used to supply energy to cooking applilances?

Need to know how this energy is produced. What is the difference of the usage, efficiency, environmental impact, availabitly, cost effectiveness of present day appliances with those of previous generations.

admin answers:

Wow! That’s quite a question!
Okay — let’s assume we’re dealing with an electric stove. The elements on the stove heat up and are in direct contact with the cooking utensil. That’s conduction. Microwave ovens work by agitating the tiny little particles in the food, and this is what generates the heat and cooks the food.
The toaster works by radiation — the element heats up and radiates heat, which then cooks the surface of the bun, bagel, bread or whatever.
It’s difficult to measure the environmental impact of modern appliances against those of previous generations. For example, where does the electricity come from? Is it generated by hydro power, or by a fossil-fuel powered generator? Availability? Previous generations used a lot of wood. It was cheap, you could usually cut your own, and was readily available. But it generated a lot of smoke. Coal was even worse. Solar powered appliances (and there are a few around, such as water heaters and solar cookers) are probably the most environmentally kind, but they are expensive and, obviously depend on a constant supply of solar energy, sso that limits their general effectiveness.
Hope this gives you a few avenues to explore.

Mark asks…

Will there be a 2009 tax stimulus rebate?

I know this has already been asked, but most of the answers are from 3 months ago. I see websites saying will get a tax credit next year and others saying we’ll get a check and others saying we get nothing at all except a TINY bit less taken out on our taxes. So what is it really?

admin answers:

None of the above.

Obama released his stimulus plan, and they mostly are tax credits for buying things that will stimulate the economy. That means you will pay the government less in income taxes if you purchase certain items. For example, if you are buying your first house, you will pay $8,000 less in income tax for 2009. If you install a solar system or wind generator on your house, you will pay $3,500 dollar less in taxes, depending on how much your wind / solar system cost you. Buy a brand new car off of the show room floor, and you will pay less income tax equal to the amount of state sales tax you paid on the new car.

So on almost all of the tax breaks, you must first purchase something to stimulate the economy. If you don’t purchase anything, you don’t get the tax break. So Obama’s plan basically benefits only those wealthy enough to purchase expensive things.

The amount of with holding ( taxes taken out of your pay check ) was reduced. But the tax schedules were not lowered, so you will have to pay taxes on the money not with held from your pay check at the end of the tax year. That gives you a few dollars more to spend, but you should be saving those few dollars to pay back at the end of the tax year.

Most people don’t realize that with less money being with held out of their pay check, at the end of the year, the may have to pay money to the government to meet the taxes owed. They won’t get a refund because less money was taken out of their pay checks.

Nancy asks…

How much electrical energy is generated from one acre of solar panels?

What i would like to know is if you were using commercially available solar panels, clustered as close together as possible and spread out on one acre, how much electrical energy is produced? if u can ‘translate’ this into terms of (1 hour of average daylight = powering a ____ for X units of time)

admin answers:

In addition to what has been previously mentioned, keep in mind that solar panel production in kilowatt hours (kWh) depends upon the geographical location and the time of year. A solar array in Boulder, Colorado will produce more in a given day and in a given year than an array of the same size in Portland, Maine. That being said you can ballpark the kWh output of an array based on its size in kW. A more refined estimate can be made if you know the location.

For example, in New England, in ideal conditions – no shading – every 1 kilowatt (kW) of solar PV will produce about 1000-1200 kWh in a year. And every 1 kW takes up about 100 square feet of space. You can extrapolate from those numbers to your acre of panels. Identify about how many kW will fit in an acre and then multiply that times the annual production.

A great source is PV Watts from the National Renewable Energy Lab:

Select the array location. Enter the array size in kW, and the program will output the annual kWh generation.
I hope that helps!

Your list of green states doesn’t even come close to an objective reality. Colorado and Idaho aren’t in the top ten, Wyoming is 37th, Kansas is 31st. Oregon is tied for first, and Washington is third (behind Oregon and Vermont), but seven out of the top ten are from the east coast.

Edit: Before you start hurling insults, you need to learn how to do research. Here is a ranking of per capita carbon output by state:

If you sort, you will find that of the list you provide (e.g., Nevada, Wyoming, Kansas), many are all way way down on the list, meaning their energy use per person is far above other states. So while you may think Nevada is a “green” state, it is not by any conceivable objective metric. The same goes for Kansas, and Wyoming is the *worst* in the nation. Furthermore, as in the original link I provided, many of the top ten states with the lower carbon footprints per capita are from the northeast, not the west. Now you can keep on acting like a brat, or you can go collect some facts for yourself and understand I am not the one who is ignorant, you are. I apologize for being the first person in your life who has told you that not everything you think is precious and special, but there is an objective reality and you would be well advised to understand that cold hard facts will get in the way of what you want to be true. Insulting people who tell you that you’re wrong is often the second course of action. The first would be to learn something. Or you can remain clueless. Tough choice. Sucks to be you. Have a nice day.

One last thing, here is a map of the top ten renewable energy producing states:

and there is a table giving the rankings. These do show a clustering in the west, but that’s because of hydropower. All of the states with high renewable fraction have lots of hydroelectric dams (NY has the Mohawk/Hudson generating, probably some at Niagara too, I’m less familiar with that area). But keep in mind hydro power has some significant ecological impacts of its own, and generating electricity that way has little carbon footprint, but there is a huge loss of habitat and natural resources. Maybe what you meant to ask is why is hydropower located in the west. But even so, Nevada, Kansas, and Wyoming are not on the list in the top ten for renewable power.

Your Questions About Solar Energy Generator Price

Steven asks…

Should we blame liberals for the ever increasing price of energy?

Aren’t liberals the ones who advocate for no nuclear power, no additional refineries, no additional sourcing of energy in America and especially no wind power generators in their “backyard”?

I’m all for solar derived energy – and for significant conservation measures – but I’m also for fiscally responsible energy measures and not financially strangulating our people and our economy.

admin answers:

Yes. They oppose drilling anywhere in America. They oppose construction of new refineries in America (none have been built for over 30 years.) They oppose construction of any new nuclear power plants. They oppose mining shale oil. They oppose mining coal and refining it into petroleum products. They even oppose any R & D for the futuristic proposal to build solar power satellites in Earth orbit, beam the energy down via microwaves, and feed the energy into the electric grid.

It is very, very clear that they APPROVE of high gas prices. Lieberman’s latest proposal would raise them even higher. It is even more clear from all of the above that they want to destroy the American economy, because they are wrongly convinced that America is destroying “the planet.”

So, by all means, blame liberals and environmentalists for ever increasing energy prices. They’re getting exactly what they want.

Laura asks…

How much is the average solar panel?

im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?

admin answers:

You are way out of your depth if your report for science class is supposed to be knowledgable.

First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don’t even mention in your quesiton.

Secondly, the only way to have a usable 12 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night.

A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels .

You also need to add in the cost of a 12VDC to 110VAC invertor, monitoring panels etc…. AND… Just how big is the ROOF of the house you are planning to use.?

This is an area of involved study and it’s a bit more than what you are imagining for your high school science class report.

Your Questions About Solar Generators For Home Use

Nancy asks…

Would a solar storm affect generators or batteries?

A severe solar storm/flare has the potential to damage the National Grid, but what effects, if any, could it have on generators and car batteries?

admin answers:

The solar storms that cause concern in operating the power grid is due to the long transmission lines traversing ground with different impedance along the route of the line. Thus the geomagnetic ground currents induced in the earth which result from a solar storm, move from the earth onto the power grid. These currents are very low frequency between 0 and 4 cycles per second. These currents flow through the power companies transformers and may force them into magnetic saturation and cause voltage distortion and harmonics to show up on the grid.

If the geomagnetic ground currents flow through the power company’s generators, a similar set of problems will occur. If you are talking about a home generator that is isolated from the grid, then no this type of generator will not be affected simply because it does not span a long enough portion of the earth to be affected. As for batteries, it is not likely that any battery system would typically be hooked up in a configuration spanning a great enough distance to see these ground currents either. It would depend on how and what they were hooked up to.

I hope this helps,


Sharon asks…

Why are radios in my house suddenly making a clicking noise?

Woke up via the radio-alarmclock this morning to a clicking noise. Every radio in the house is doing the same thing, no matter what station they’re tuned to. It’s an extremely distinct clicking sound, with absolutely no semblance of any radio station whatsoever. It sounds like a very fast metronome.

Any ideas of what could be causing this? I was thinking it was some type of solar activity, but haven’t seen anything on the news about it.

admin answers:

When I was a kid, I sometimes heard rapid clicking noises coming from my television when small planes were flying nearby. It turns out that there is a solenoid on certain kinds of engines that give a pulse that can interfere with radios and whatnot.

I bet you have a neighbor running a generator or there is some other source of such interference outside of your home (but not too far away.)

The person causing the problem may not even be aware that he is interfering with your radios.

Your Questions About Solar Energy For Kids

Laura asks…

How could I get an insight into renewable energy, with possibly a summer internship?

I’m 16, and will be 17 by the summer, I’m still in Secondary school and I would really like to get some sort of insight into renewable energy over the summer, as I would like to persue a career in that field. I live in Ayr in Scotland, so it would have to be near there possibly out to glasgow. I’ve no idea how to go about it, and I don’t know what company I could go to either. The company I could think of is EDF Energy. I thought of maybe writing an email and asking if I could come in and maybe help out, getting coffee etc. Any help would be great!

admin answers:

Hi Alice. Not being from Scotland, or the UK, I would offer two suggestions. First, get a subscription to a magazine called, “Home Power.” We started reading it 13 years ago, and 12 years ago we went to one of the energy fairs listed in the magazine. Today our home is powered by the wind and sun, and we teach solar power seminars at the local schools, and host field trips to our home for the kids regularly. You interest is a bit deeper than just setting up some panels, and that’s great. Any possibility of finding your way into an internship would pretty much require you have some expertise in the area, not schooling, just better than basic understanding. Starting with that magazine is a great first step. In the back is a calander section that lists happenings, such as fairs.

There is a really big fair each year in Aberdeen each May, I don’t know if you can work out a trip there, but the great thing about a fair is you can learn a lot quickly, and meet just about anyone worth meeting if you want to get involved somehow. The fair we went to had the entire editing staff for that magazine in one booth, and since then I’ve contributed a couple articles for them they have published. There might be other fairs closer to your home, but I’ve clipped the website to the group hosting the Aberdeen one below for you. Try googling, “Energy Fairs in Scotland.”

Any up and coming technology or business is always looking for someone like yourself, who is interested in the technology or work, has energy and some knowledge, and wants to help. The job facing you is just connecting with the right people. An energy fair is the best place to go if you can get to one and have an interest in working in renewable energy. The second link is for a listing service that have some energy fairs listed in Scotland, worth looking into in your case. It’s a great field Alice, and I encourage you to get involved any way you can. Start by learning all you can about the technology. Take care, Rudydoo

Your Questions About Solar Energy Generator Companies

Linda asks…

Do you believe that solar energy could power the entire USA? Are oil companies preventing solar energy?

Are the oil and nuclear industries tamping down on the development of new renewable energies to protect their own industries? Are renewable energies actually not viable at all?

admin answers:

During Bill Clinton’s administration, his energy supervisor had a plan to power the Southern and Western United States with Solar panels installed on the roofs of home owners. The Middle and Eastern United States with water, wind and Nuclear plants. It would of basically supplied our country with electric without fossil fuels. They fired him!

Next Point: America is sitting on the largest supply of Natural gas in the world. Natural gas is also made from our sewage plants and from dairy industries (manure). This can be used to power engines connected to generators to produce energy stopping green house gases from just going into the air. Some dairies are already doing this to power their businesses. Why are we going with ethanol which is impractical to power vehicles when natural gas/propane powered vehicles are clean burning and efficient?

Mary asks…

What is the least expensive way and how to have electricity independent of city services for a residence?

I want to set up a house, at first i thought of solar and generator but was not specific enough, totally independent of electric, water ect of city services.
I am in Mexico so plenty of sun, a bit of wind or breeze every day.
Also on a budgeted income this needs to be cost effective.
The house has 3 bedrooms, living room kitchen, dining room and 2 bathrooms.
Made with cement an brick and tile floors.
Ask a question if I have not adressed it and I will add it in details, Thanks you.
Wonderful help and ideas I want to say thank you to all.
For more info our house is now
water heater, stove: propane
refrigerator: electric
several fans to cool down the house as my wife is from USA and a mother who is ill that need to stay not too hot.
Mexico actaully is very conservative in energy.
All electric is turned off and unplugged when not in use.
Water heater is not on, (not even a pilot) when not in use, for showers light 30 min prior.
My wife tried this in the states.
it cut her bill down by 7/8th cost of her monthly bills in energy use.
I just want to be able to use a air conditioner or heater without having a quadruple size bill, as if energy is used past a certain point the bill jumps dramatically.
This will insure a happy wife and mother and my pocket left with a bit of change in it too still left.

Tranquility will be wonderful..haha

admin answers:

In your area solar makes the most sense, but you could start small and work up. Depending if you have any power source at all at this time? Having an alternative energy source usually means you must be willing to alter your consumption of power, sometimes drastically! But the satisfaction of being off the grid is something that is very satisfying! Even when you go without some of the things most other people have.
We started with what was there at the house we bought. A generator. Then we added a solar system. We added more panels and more batteries eventually, and upgraded the type of batteries. If I still lived there it would be great to add wind, for when there is no sun. The property is on a hill, so there is almost always a breeze somewhere! There is also a small water resource, but probably not enough to utilize in a cost effective manner. There are some great Yahoo Groups that deal with this subject matter, search them and have a great time!

I lived with solar power and a generator for seven years… My ex still lives there and the system has been in place since 1989. Still goin’ strong… Still a viable alternative. It cost the same as hooking up to the grid when we considered how many poles it would take to get the power to the house… Then the power company wanted to put a transformer in the front yard. Nope… We said “I don’t think so!” and we’re still glad we did!

Your Questions About Solar Generators Reviews

William asks…

are there solar radios which work?

Even if it is a cloudy day and through window glass? I’d like to get an emergency radio with a solar panel. I know there are models which have solar panels, but I don’t know if they actually provide enough power to run the radio. I tried to read through consumer reviews and for the same product some people say it works, other say it doesn’t work. Now I am confused. Any ideas where to start?

admin answers:

I’m a big fan of solar, but a solar-powered radio doesn’t seem robust enough for emergency use. Even if the solar radio charged internal batteries, what if I forgot to leave it in the sun, or the batteries went bad?

There’s a kind of radio that you wind up, and the spring spins a small generator that powers the radio for about half an hour. That would be my first choice, followed by the kind of radio that you must continuously crank to keep it running.

David asks…

I am considering a solar PV installation and I am a bit confused as to the size of the system I can have insta?

lled. One company has offered a 4 kw system and another company says 3.6 is the largest system I can have. They mention regulationG83 as set out by the DNO and if I had a 4 kw system installed they could insist it were downsized. Please help my aching head!!

admin answers:

This has to do with the Utility you are connecting to and if they have the capability to accept your pushed (unused) electricity generated.

If they are not able to accept it, they may consider modifications to their system to receive it, all at your expense of course. The extra .4 Kw (point 4) generated and the savings you get from it are probably minor compared to the Utility’s construction or modification costs to accept your pushed electricity. You would pay more than you would ever gain making this a poor choice.

So yes, if your solar contractor has calculated 3.6 it is because they based the number on the usage of your home and the connection to the utility grid. You are the “generator” of this electricity…which has to “play nice” with the utility’s existing equipment capabilities. That company used what is called “Best Practice” which they obviously considered when designing a system to meet most all of your needs and still comply with the G83 requirements.

The other company is probably accurate in the amount you consume but didn’t take into consideration all project needs start to finish. You could possibly still install this 4 Kw but remember at the end of the project you might be faced with surprise change order costs to modify for grid connection issues. Make that contractor spell that out for you and who will be responsible for those change order costs.

I found an interesting synopsis and copied this clip from it. Link for credit also included

“It would be a pity to complete an installation at a location which could not accommodate the generator output. It is for this reason that G83/1 and the ESQC Regulations limit the output of generators to 16 Amps per phase …. (You being the generator of that electricity)
Generators with an output in excess of 16 Amps per phase can be connected to our network, and part of the G59 procedure is a review of the effect of connecting the generator. In some circumstances we may have to carry out work on our network to accommodate a generator and part of the costs of this work are borne by the customer.”

Your Questions About Solar Energy Environments

Jenny asks…

Why isn’t the federal government willing to subsidize solar energy panels for homes?

Some states like TX and NJ will subsidize solar energy 40% worth.
But the technology to date has been quite costly in spite of these states’ subsidizing the cost. However, solar energy is starting to turn the corner cost-effectively in the past year or two.
Why is there no serious encouragement from the federal gov’t to encourage homeowners to install solar energy panels by offerering subsidies or rebates for installing it?
Would this be a good idea?

Steven asks…

Why is solar energy a renewable resource and also some advantages and disadvantages of using solar energy?

Please tell me some disadvantages and advantages of using solar energy. I also need to know why it is a renewable resource. Can you also tell me how much of of solar energy is left and how long it will last. Thank you so much. [Tell me some websites to vist about this information]

admin answers:

First, its all a guess but the sun will continue to shine for about another 2-4 billion years. So for all practical purposes, its eternal.
Solar energy depends on sunshine, one disadvantage is cloudy, overcast, rainy, snow etc. Days. No sunshine, no real energy. Another difficulty is converting solar energy, solar panels generate direct current (DC) and this has to be converted to AC current to run appliances, etc. In your house. In order to store solar energy, batteries are required, so the DC current from the solar panels can charge the batteries, and then the DC current must be converted to AC.
Solar panels are not cheap but the price is coming down. They also don’t last forever and can be damaged by hail, etc.
The good news is, solar energy is clean, not pollution except for the manufacture of the panels and for the moment, sunshine is still free.

Your Questions About Solar Generators Portable

Lisa asks…

if you leave a car continuously running, how large an inverter can be placed on it to make electricity?

I am trying to find a cheap back-up option for portable batteries that are solar charged. Could a car with a 2L engine run a 4000w or 5000w inverter to give 240V electrical power?
I want to power a food kitchen in a caravan for 4-6 hours a day in summer at the beach. Later I would like to have enough solar panels and deep cycle batteries to do it mainly by solar, but want a cheap start-up option, and a back-up later on. Would a car be as fefficient than a generator if excess power was stored in a few deep cycle batteries.

admin answers:

What you are interested in is the capacity of your alternator, not the horsepower of the engine itself– unless you plan to drive an external generator off of the engine, e.g. Using a PTO on a tractor.

Unless you are using a vehicle designed for it, e.g. An ambulance or other vehicle with a large air or water cooled alternator, you are going to get something on the order of 50A at around 13V from the alternator, which is on the order of 650W.

The alternator is not a power-heavy device. It’s purpose is to supply the amount of juice needed to run a cars lights and electronics, and in modern engineering practice it’s not going to be oversized. What you are thinking about doing is similar to buying a clock to plug in to a wall so that you can use the second hand and a pulley to try and lift a heavy piece of furniture. You are much better off just buying an electric motor that uses the same power source. In your case, unless you have a direct drive off of your engine, that means buying a gasoline powered generator:

If you DO have something, like a bus, that has a larger alternator, I doubt that it will be cheaper to idle the vehicle’s engine. Traveling food service that I have seen either rely on a gasoline powered generator like above, or run on propane, aka lpg–this is a great solution for lighting and cooking, and you might be able to find a good, used propane powered refrigerator/freezer for around $500.

James asks…

can anyone suggest an affordable, portable solar generator?

I live in a hurricane zone. but, i hate my neighbors who use those horrific and loud generators 7/24 when we lose electricity.

admin answers:

Affordable, portable and solar “generator” sadly do not coincide; especially if you are talking about running more than a window fan. Solar power systems require a bank of wet cell batteries to charge and it’s those batteries that supply your power. They need to be connected through an inverter system that converts the direct current to alternating current… Another large and costly device.

Honda has some very quiet generators. That would be your best choice.
