Their guide only covers solar power. If that is all you are interested in then this might be the guide for you. Depending on where you live, solar panels can also generate a chunk of electricity for the home, significantly lowering energy prices. First, compare this to professionally installing solar panels. Solar panels and wind generators are simple to make, and the materials are so low cost that you can run your entire home on natural energy for less than $1,000. This is a huge savings when you compare it to commercial renewable energy systems, which can cost up to $36,000 per home.
The process of learning how to build a solar panel or how to build a wind generator isn't expensive either. For an investment of about $200 you can get a great return. You can expect to spend as much as $2,000 to $3,000 on a single arrangement for generating solar or wind power for your home. However, with Earth4Energy, you can set up a whole unit in approximately $200, which is one-tenth the cost! John Holdren will not lead the new President down the primrose path of false hopes based on solar, wind and nuclear power. John Holdren knows and can clearly articulate why it is we need a new form of energy generating technology.
