Generally it's worth investigating the economic viability of installing a solar hot water system if you have an electric water heater with utility rates of at least 5 cents per kilowatt hour and have tax credits or rebates available. (It may even be worth changing out a gas-powered water heater if your costs are at least $8/million BTU).
When discussing the subject of alterative energy it usually the topic of solar power that first springs to people’s minds.
By all accounts, active solar power runs the full spectrum. That is to say, it can heat and cool your house.
While the idea of using the power of the sunlight has been around for more than 100 years, it was not until the late 1970s that a genuine effort was made to learn about what is solar power and how it can help reduce the world's reliance on non-renewable energy sources.
As the demand for alternative energy continues to increase, the number of suppliers and options for solar power kits are increasing.
The future of solar power is looking promising due to advances in technology and government incentives.
With a small investment, a single solar panel can be built in order to supplement utility company electricity.
Solar energy is first of all a very useful source of alternative energy, as it can provide electricity during power failures.
Given that efficiency of solar cells should increase and the costs will come down, it makes a lot of sense to get a solar panel for your home.
Although the first solar power cell was made with gold and selenium, it was much more inefficient than the silicon solar power cells of today.
