The switch from one energy source to another has not been seen since the first part of the 20th century. Then, people all around the world relied on horses for transportation and gas lamps for light. Then, came the world-wide use of fossil fuels and the introduction of automobiles and electric bulbs, which revolutionized the way people lived.

You have probably heard it said by environmental groups that we should switch to solar energy as a power source because it is free, there is an unlimited supply, and it is a cleaner source of electrical power because there are no by-products (compared to fossil fuels like oil and gas which release greenhouse gases into the earth's atmosphere when burned for power.) However, can solar energy be a reliable and practical source of electrical power indeed?
Although it is much less expensive to initially get hooked into the local electric company's grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one's energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling. The article explains what renewable energy is and the most common sources of renewable energy.
