History of Alternative Energy / Alternative to what?
The history of the alternative energy sources dates back to ancient times. In fact, any new fuel, discovered by humans, became alternative to the old ones at some period of time. For example, in the Middle Ages coal became an alternative to wood, which people commonly used earlier to heat their houses and cook food.
Later, at the early 19th century petroleum became an alternative option to whale oil, which was widely used for lighting lamps and resulted in serious destruction of whales in the oceans. The dawn of the 20th century was marked with the appearance of ethanol as the alternative to gasoline.
However, nowadays we put a new meaning into the term “alternative energy”. Today alternative energy is that derived from the sources, which do not deplete or exhaust natural resources and do not harm the environment. Modern understanding of the alternative sources of energy appeared about 1970th, when the most developed countries first felt the shortage of gas.
