My Father in law is a genius
My father in law made a switch to be put in line with an inverter and a battery and it shuts off the battery juice to the inverter thus no drain on the battery from the inverter.
Interested in wind power?
This is a cool info blog on used wind systems: http://www.mywindpowersystem.com/marketplace/

a neat wind power article
Duke To Build 200-MW Top of the World Wind Farm, Ninth in the US
North Carolina, United States [RenewableEnergyWorld.com]
Duke Energy said this week that it plans to build and operate a 200-megawatt (MW) wind energy project near Casper, Wyoming. Known as the Top of the World Windpower Project, it will be the company's ninth U.S. wind farm and its fourth in Wyoming.
The project will feature at least 66 G.E. turbines with a capaity of 1.5 MW each.
Duke Energy will construct the Top of the World project on approximately 17,000 acres of private and public land it holds under long-term lease in Converse County. The project could reach commercial operation by the end of 2010.
PacifiCorp, which operates as Rocky Mountain Power in Wyoming, will purchase all of the electricity generated by the Top of the World project and the associated renewable energy credits (RECs) as part of a 20-year power purchase agreement.
PacifiCorp previously contracted to buy all of the output and RECs from Duke Energy's nearby 99-megawatt (MW) Campbell Hill Windpower Project, scheduled to come on line later this year.
"We've always believed Duke Energy could become a major player in the wind power industry if we adhered to our strategy for organic as well as opportunistic growth," said Wouter van Kempen, president of Duke Energy Generation Services (DEGS), a business unit of Duke Energy that owns and develops renewable energy assets. "Including Top of the World - which will be our second-largest renewable energy facility - we'll have committed to four new wind projects totaling more than 360 megawatts this year alone."
Duke Energy expects to start construction of the Top of the World project in late 2009 or early 2010, upon receipt of all necessary permits. The project will feature at least 66 G.E. turbines with a capaity of 1.5 MW each. These units represent the balance of turbines Duke Energy arranged to purchase from G.E. in a procurement order announced in September 2008. Negotiations for the remainder of the wind turbine supply to be used at Top of the World are underway.

However, the initial expense in creating the solar panel array can be quite high, especially if one buys a prefabricated panel, and become a victim of shameless profiteering. A single solar panel can go for around $500 to $800, with the most expensive parts being the solar cells (but only because you really need a lot of them). After the solar panel is up and working, maintenance cost is quite low. The problem is that an ordinary house will need more than just one panel.
For every problem, there is a solution. The answer to lowering the costs of installing a solar panel would be to build one from the ground up. There are hundreds of Do It Yourself kits in the market, and these come in different sizes. Should one feel doubtful about their building skills, they could always buy the smallest ones first, which are usually used as educational tools. They cost a lot less and the task would not be as overwhelming.
The next size to try would be the type of solar panels that will power only specific equipment or appliances, like the water heater or the Jacuzzi. After a while, the builder will probably get the hang of it and be churning out panels to cover the roof.
A school DIY kit often costs less than $100, and a full solar panel will cost about $200. Even if they mess up one kit and be able to succeed only on the second kit, they would still be able to save at least $100, though it really is not as hard as it seems. With a bit of practice, anyone can do it.
Another advantage of building the solar panel is the satisfaction of being able to create something useful with one’s own hands. It may not be a work of art in the first few tries, but it’s really not a beauty contest anyway.

A neat new article
The green energy trend has certainly picked up momentum in the last year alone. Alternative energy researches that have long collected dust or put in the back burner are now taking the world stage, front and center. One of the leading contenders for this new (and hopefully, sustained) green energy research is finding a way to be more efficient in turning the sun’s light into electricity.
The idea that light can be turned into electricity (the process is more scientifically known as the “photovoltaic” effect) is nothing new, but the efficiency of the process has always been a little off. In the beginning, the first solar cell had a conversion efficiency of 1%. This means that only 1% of the light that is absorbed is actually turned into electricity. Today, that rate has come a long way, about 40%. It really isn’t comparable (yet) to the way fossil fuels can generate electricity but there are a number of advantages to sourcing electricity from the sun than from fossil fuels, like being environmentally friendly and easily installed.

Wind is growing
Signs of Impact
Project numbers and developer feedback indicate that the economic stimulus package is on the right path to bolster activity within the wind industry.

Washington, D.C. United States [RenewableEnergyWorld.com]
On July 9, the U.S. Treasury Department and U.S. Department of Energy released the guidance for how wind farm developers can access cash grants in lieu of the investment tax credit. The grants, which were part of the American Reinvestment and Recovery Act (ARRA, also known as the stimulus bill), are expected to help get wind projects built while capital markets remain difficult. The program began accepting applications at the end of July.
