How many kilowatt hours would I need to power a town of 1000 people plus businesses and a mine?
If i had a remote alaskan town of 1000 residents, how much power would I need to generate to run the whole town. Would a diesel generator work?
You didn’t give enough info.
1000 people and business plus mine isn’t specific.
What kind of people? Treehuggers? Hippies? Or the typical super-wasteful American stereotype?
What kind of business? Small things like the mom-n-pop stores? Small-town restaurants? Or a giant general motors automobile plant? Or what about a server farm (which requires lots and lots of power)?
For a mine, again, it depends of what kind of mine. How big is the operation? How updated is its facilities? Is it a pit/strip mine? A tunnel mine into the side of a mountain? Or a deep mine that goes way into the earth?
Then you have the climate. Alaska narrows it down some. Its cold there. But you forgot to say how is the town heated. Oil? Gas? Electric? Solar? Geo-thermal?
No matter the answer, I can tell you unless the town has tiny mom-n-pop businesses, tree huggers and hippies and an obsolete open pit mine, you’ll need a lot more than a diesel generator. You can try something green- like geo thermal, wind, tidal power. If you embrace the power of the future, nuclear power is the way to go. You can have an oil-fired or coal fired plant. It can run on natural gas or methane from composting waste. You can even have one burning trash to make power.
How much kW of power?
If each house had 4 people, then it would be about 250 households. Each household would consume about 15 kW a day of electricity.
So for homes you have 15×250 = 3,750 kW
business, say you got small ones and one Costco store.
Say 10kW electricity for 12 small businesses and 40kW for the Costco (they have lots of lights and fridges).
So business you have 12×10+40 = 160 kW
say you got the average open strip mine. A small operation that employs 350 people. Its not high-tech. It processes gypsum (different types of mines uses different amounts of electricity) for another plant in nearby Anchorage. That stuff is shipped by rail. I’d estimate 2000kW energy.
homes: 3,750 kW
Stores: 160 kW
mine: 2000 kW
you need to generate at least 5,910 kW a day or you’ll have power issues. If all the homes are electric heated and not gas or oil, add another 1000kW a day.
In all, you needs at least 6,910 kW a day, but not more than 9,000 kW. The 2,000 kW a day difference allows some flex and deals with expansion of the town or unexpected high power consumption.
Remote Alaskan towns should not rely on diesel, or anything that needs to be shipped in. If the shipment is late or not coming, everyone could freeze to death. You’d want something that comes out of the earth reliably. Like geothermal. The earth won’t die for a very long time. If you place the plant near a volcano or place with thermal activity, you’ll get good, reliable high power output for the next couple thousand years or so.
What is the best book for building an electric car?
I want to begin the project of building an electric car, can someone tell me what the best book to aid in this process. I am a novice.
The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.
However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…
Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.
If you interested I offer several DIY alternative guides to walk you step by step threw EV conversion process at agua-luna com or
www agua-luna com
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Where to buy an affordable Solar System in Saudi Arabia?
Does anyone knows where to buy an affordable Solar Energy Generator for the use of homes or remote farms in Saudi Arabia? I would appreciate solutions in the Eastern part of Saudi better. Does anyone knows if the technology now is practical in Saudi and do you have any information on people who have used these on small scales like homes?
Have you considered building your own?
Resources and parts to build them are pretty common place these days. There is lots of info around on how to do this.

What do you think will be the next big thing in energy?
Few years ago we had horse powered cars, then came the steam powered engines, and now we have fuel powered engines.
There are some cars in the market that work with electricity today, or solar energy, but none of them have yet addressed the needs of the market, what are your thoughts? Are we going to see or more probably our kids are going to see a new set of vehicles propelled with some sort of energy that replaces petroleum based fuel?
I think plug-in hybrids like the Chevy Volt will be a big deal.
For the short trips, it’s all-electric. No gas needed.
For longer trips, you have a small gas engine to generate electricity for the electric engine. And that engine doesn’t have to be gas either. E85, biodiesel, butanol, etc.
The possibilities are endless.
Why did Ronald Reagan rip out the solar panels Jimmy Carter installed on top of the White House?
Sure, Jimmy Carter’s administration was a mess.
But solar energy was a legitimately good idea.
Why did Reagan remove the solar panels (at TAXPAYER EXPENSE, no less…) that Carter had previously installed on top of the White House?
What was the point?
What did Reagan actually do to decrease America’s dependency on Mideast oil – anythng?
The day the votes were tallied and we got the news that Reagan had won, the very first commentator asked him what his plan was to boost the economy.
He answered “I don’t have a plan.”
The commentator then stated ” But Sir, when you campaigned you said you had a plan.”
Reagan replied ” Anybody that was running for President would say they had a plan whether or not they really did have a plan.”
This told me right then and there that this man was a great Poster Boy for Opportunists everywhere.
I never believed another word that came out of his mouth, just like Bushie Boy Jr’s.
Far too many Americans died from AIDS during his term of office, mostly because he denied there was such a disease, so absolutely no Fed. Dollars were appropriated for AIDS/HIV Research, Care, or Prevention during his reign.
As far as ripping the Solar Panels out, he did this for two reasons.
One was because Nancy Reagan, being the Liberal that she’s always been, liked them, and Ronnie hated anything that Nancy liked, even her grown kids.
The second reason was out of pure spite.
I can’t tell you how much of a bad President he was.

Best Solar powered generator capable of running a small refrigerator and a few other appliances such as charge?
rs and lamps? pretty much a generator for keeping a house up and running when all of the power goes out. And one that charges in the daytime particularly in 6-10 hours. Reviews or personal experience would be awesome thank you.
Considering the purchase, installation, maintenance, and replacement costs of solar photo-voltaic panels, you’re paying 38 cents a kwh for that power and that’s without batteries, coal costs 1 cent a kwh and natural gas costs 15 cents a kwh. Solar is not a backup power source, it’s only viable if subsidized by the government or if grid power is unavailable in your region.
If you want a backup power source, buy a portable tri-power generator, install a transfer switch and a natural gas valve and you can run your house on natural gas if you loose your electricity, if the natural gas line has been interrupted, you can run on propane, if you can’t get propane, you can run on gasoline. If you’re off the grid, it would be a good idea to use an absorption refrigerator, they can run on natural gas, propane, or kerosene. A large propane tank can be put under your yard for free if you agree to purchasing a certain amount of propane each month. A heat fired refrigerator is often used because of reliability as losing the refrigerator means losing your food.
What is your experience with the solar generators that are advertised on the web?
They cost about $1500 to $3000 depending on power. A panel, a charge controller, huge lithium battery, inverter.
I’m not asking if the price is right. They sound so sensible I’m wondering why they aren’t being offered by the larger manufacturers?
Anyone have any experience?
Without a link to the products you are talking about, it’s hard to give an accurate review. My guess is they are either kits that have been put together from the basic components, the few I saw from a Google search were just all of the components available at any solar equipment provider or an all-in-one device that combines battery, charge controller, and inverter that you plug a solar panel into. They are off-grid systems, which means you can only power the equipment from that battery, if the battery runs out (during a rainy stretch of weather), then you would need to unplug from it and plug into your regular electric. Duracell is rebranding an all-in-one device, except for the solar panel, that is made by Xantrex, and selling it as their own, so the big companies are starting to get into the game.
Something that size is probably just good enough to either provide emergency backup power in the event of an outage or enough for a cabin. A one-size-fits-all system is hard to make to work for most people. We put together kits that are a good starting point, but are often customized to meet the customers particular needs.

What are the best three electrical energy suppliers?
[Location no object] Can anyone give me the details of three electrical energy suppliers that offer the best value for money?
And any additional details about the company…(Website etc…)
Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.
Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 120.8 gigawatts. Although wind produces only about 1.5% of worldwide electricity use, it is growing rapidly, having doubled in the three years between 2005 and 2008. In several countries it has achieved relatively high levels of penetration, accounting for approximately 19% of electricity production in Denmark, 10% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008.
and Waves,(as in ocean waves)
Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy.
The problem is that it’s not easy to harness this energy and convert it into electricity in large amounts. Thus, wave power stations are rare.
Today the largest use of hydropower is for the creation of hydroelectricity, which allows low cost energy to be used at long distances from the water source. Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably different output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 715,000 MWe in 2005. This was approximately 19% of the world’s electricity (up from 16% in 2003), and accounted for over 63% of electricity from renewable sources.
Some jurisdictions do not consider large hydro projects to be a sustainable energy source, due to the human, economic and environmental impacts of dam construction and maintenance.
where do you find info on converting fruit waste into energy?
ok im in 8th grade advance science and i want to do a science fair project on converting fruit waste into energy but im having issues on finding Information help me please???!!
or if you have a better idea on how to wow the judges but have the experiment be something that has to do with environment that would be much appreciated.
There are 3 ways to utilize organic waste for energy.
1 biodiesel -corn/soybean/any oil
2 methane -mostly animal waste
3 ethanol -sugar/starch vegetables
Since fruit has a high sugar content you will want to produce ethanol. You will want to search the web for wine making(drinking alcohol is wine) The process is simple, just add water and yeast to the container and keep it sealed at room temperature.
Tip: If your fruit waste is clean i would put it strait into a container. If its not, I would cook it first to make sure all the bacteria is killed. You wan the only think living in the container to be yeast otherwise it wont work.
Here are the steps to energy production:
1. Fruit waste
2. Yeast creates ethanol from sugars
3. Remove Juice (compost the solids)
4. Distill the juice( to seperate the ethanol from the other stuff)
5. Burn the ethanol with alcohol burner (you can use a peice of cotton rope poked through the top of a container filled with ethanol)
This would be a very cool project. The alcohol burner is simple, but it represents ethanol being used in a car, generator, etc.
For a first attempt you may want to add some sugar with your fruit waste just to make sure it works. Once you have the process down you can remove the sugar.
This is a hard project. If you run into stumbles, ask lots of questions. If your project doesn’t go fully as planed, explain to the judges the process, what you learned and what you would change.
Best of Luck!

What type of home construction in best suited for the climate of Denver?
What climate factors need to be considered when building a home in Denver?
How well should the house be insulated?
What is the number of heating degree days?(mean below 65 degrees F)
What is the number of cooling degree days?(mean above 85 degrees F)
Is solar energy an option?
Should I worry about water conservation?
This is not a homework question! I am looking to move there and have herd lots of bad things and am looking to build a home and need help figuring it all out because my husband is an idiot!
To get really accurate answers you will need to ask a home construction person, but I will give you some rough ideas.
>> What climate factors need to be considered when building a home in Denver?
Denver gets cold. It can get below zero and stay there. In summer it can stay over 90 for weeks. The heat and cold are dry so it rarely gets really hot or really bone-chilling cold. I consider Houston really hot. I consider the east coast really cold. I have never been that miserable in Denver. A well constructed, well insulated, passive-solar designed, south-facing house is a big plus.
>> How well should the house be insulated? I would suggest R30 or above
>> What is the number of heating degree days?(mean below 65 degrees F)
At night temps gets below 65 a good deal of the time. A well build house will retain heat so there is no need to turn a furnace on until it gets a lot colder than 65. I have friends who turn off their furnace from May to September.
>> What is the number of cooling degree days?(mean above 85 degrees F)
I was born in Colorado, and have never used air conditioning in a house. You get a few well places fans and there is no need for air conditioning. Again, dry heat.
>> Is solar energy an option?
Absolutely! With over 300 days that are at least party sunny, solar is an excellent option. Passive solar is one of the best options around. See the link to CRES last time I answered your question
>> Should I worry about water conservation?
Absolutely! Colorado is high desert. We have serious water shortage problems that are only partially being addressed. Consider xeriscaping your yard and use water wisely.
How much energy does Colorado use a year?
hello could you please tell me how many MW of energy Colorado uses a year? and also what percent of that is made up of solar and wind energy? What is the most common source of energy? Were there any solar and wind plants 10 years ago? If not, could you please tell me when they first arrived?
