Been looking at this one for a while myself. Solar is just too expensive for me to get into right now. I’m keeping the potion open for a latter time when my finances are better. A basic package system that can SUPPORT about a third to half of the usage of the typical american home will start at around 7 to 8 grand not counting install cost. Wind is cheaper and readily available by hundreds of suppliers, but, the output can vary widely even in areas that have a constant wind. Wind in my opinion is better for a supplemental system. These are the two most common. Also seen a farming operation that powers its own generators from biomass off its cows waste. Use is kind of limited on this one. Bio diesel generators don’t have enough efficiency to relay consider unless you live way off the grid and only use electricity for short periods. Using small water wheel systems in some parts of the country but with the same problems as wind. Right now with solar its about how much you want to spend up front and what do you want out of it? I’ve so far just gone to all CFL bulbs and improved insulation which has chopped off almost half of my bill with that. Thinking about doing a roof overlay that will add 3 inches or more of insulation and a tin roof over my existing asphalt shingles. Probably cost me around 3500$ for this as it requires no additional support or rework of the roof other than extending the vents. Most available packages either come with vent extensions or they will send the ones you want when you order the kit. The one I’m considering includes installation.

You’re asking a difficult question only because the technology is improving each month. What is the best today probably won’t be the best next year. For wind power you will need a wind availibility survey describing the average wind conditions throughout the year for your locality. Every homesite is a bit different. To establish a cost/benefit analysis your first have to know how much wind energy is available.

Fossil fuels always release more pollutants, including CO2 if you consider that a pollutant. Hydroelectric electricity has limited availability, and it’s a resource that is pretty much tapped out – every river which can be dammed for electricity already is. Solar energy is expensive, far more expensive than anything else. There is a lot of variation is solar panels, but it often involves rare earth elements, which limits the total numbers of panels which could be produced (at a number too low to matter). Solar energy is also not very energy dense. The total land it would take to capture the same amount of energy using solar as can be generated using nuclear is tremendous. States worth of land. Unlike oil, we have a lot of uranium locally, and the other nation with big resources is Australia who we’re on pretty good terms with. And if we had some modern reactors, there would be much less nuclear waste produced. In fact, some of the new plants can eat material which was previously considered waste.

Since heat is what energy through inbody is released, about 25 – 30% of it comes for solar energy.

On more fact is that, beside energy consumption, it also tends us to feel tired and lazy ……. This is because … Sometimes the heat accumulated by the skin cells from the sun is complexed and as a result it dehydrates our body.
