What is an alternative energy?

Alternative energy is the name given to any type of energy used to replace another energy source, often due to the negative consequences of its use. The types of alternative energy throughout history included coal, oil and alcohol. In the 21st century, these alternative sources included bioenergy and biofuels such as palm oil, ethanol and other low carbon alternatives.

In the Middle Ages and the Renaissance period from 1200 to 1500 years, coal was used as the first source of alternative energy. When the forests began to disappear due to the significant need for wood in any modernization world, coal was introduced as an alternative. Three hundred years later, at the beginning of the 18th century, oil was used to replace the exhausted whale oil source for fuel lamps. The inventor Alexander Graham Bellnavrhted using ethanol oil based on maize in 1917. These reusable energy sources began to be used in the 50s and 60s, especially in the United States and Brazil. In 2008 it was two bestEthanol oil users in the world. Brazil, in 2008, had more than 35,000 stations that offered ethanol fuel in addition to gasoline.

In 2000, various sources of biomass were introduced as another alternative to harmful fossil fuels composed of recently deceased organic matter. Other recent sources were zero carbon alternatives with low methane emissions such as hydrogen and nuclear energy.

Alternatives for transport energy were one of the most studied places for alternative energy in the United States and worldwide. With rising gas prices, many options appear as gasoline substitutes, including the previously mentioned ethanol fuels. Other sources included Electric and hybrid vehicles, as well as fuel cells and flying wheels.

In the recent history of the use of alternative energy, it has stimulated controversy among some suppliers and energy manufacturers. TeRail, which allows government incentives, some fought to include fossil fuels and nuclear energies as a source of alternative energy. Others, however, argued that the negative consequences of these sources - their carbon dioxide emissions - exclude them from the category. In the eyes of many, alternative energy sources in the fight against negative energy problems that create more by contributing to global warming.
