Today, photovoltaic cells only contribute a small proportion (approximately 0.04 percent) of total electricity in the United States. At the same time the production of solar panels has growth rapidly per year by around 20% growth in the 1990s and photovoltaic panels prices decreases every year. Annual worldwide solar panel production (including solar panels with homemade solar power homes) is about 400 MW per year. Based on the total cumulative capacity figure, it is already reaching 2 GW.

Some of alternative fuel sources are by no means new. For centuries people have harnessed the power of running water for a variety of needs, particularly for agriculture or farming. Water wheels were constructed in the Middle East, Greece, and China thousands of years ago, and they were common fixtures on the farms of Europe by the Middle Ages. In the early 21st century hydroelectric dam, which generate electricity from the power of rivers, provide about 9 % of the electricity in the United States. Worldwide, there are about 40,000 such dams. (more…)

Solar generators such as solar cells can easily generate enough electricity to power your home independently in any given month. Truthfully you can even build your own homemade generators with a solar generator plan for around $100 which work just as well as professional ones which would cost you roughly $2000-$3000 to have professionally built and installed.
