Tonight, the world over, people are looking for backup sources of energy. The reason is because of 2 major main reasons. First, the first sources of energy are becoming more costly by the minute. Second , also they are also depleting at a very fast rate. Almost all of the nations are busy searching for renewable sources of energy, so that their increasing energy demands can be met. At the grassroots level also, the people are fighting to keep their energy bills cheap.

Among the renewable energy sources that produce electricity, hydropower is the most common one. It calculated for a 7 % of total U.S. electricity generation. It is among the oldest resource of energy and was used many years ago to revolve a paddle wheel for reason such as grinding grain. The first U.S. hydroelectric power plant opened on the Fox River near Appleton, Wisconsin, on September 30, 1882. Before that, coal was the solitary fuel used to produce electricity.
Fossil fuels are non-renewable source of energy, it means it could run out. Also, when fossil fuels are burnt they produce the gas carbon dioxide (CO2). Carbon dioxide is known as a greenhouse gas since it traps heat from the sun & preventing it from escaping out of the Earth's atmosphere in to space. The amount of greenhouse gasses in the atmosphere is increasing. It leads to rising Earth temperature called global warming.
Alternative energy is energy that is renewable and naturally occurring. Alternative energy does not produce pollution and is a safer, cleaner and less destructive method of obtaining energy than using fossil fuels. Alternative energy, by its very nature, is not harmful to the Earths environment. Due to increasingly high gas prices and concerns over damage to the environment many people have begun looking for an alternative energy source to meet their needs. Fortunately searc...
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.
