Are There Any Realistic Alternatives To Oil?
While energy cannot be created or destroyed, it can be transformed between types. The main sources of energy on Earth are the fossil fuels, including coal, natural gas, and oil, and all of these are nonrenewable resources. Each of these were produced over a period of millions of years under the surface of the Earth, and it is not possible to renew these supplies. The main uses for the energy obtained from the fossil fuels include heating our homes and buildings, generating electricity to run everything from computers to alarm clocks, and providing transportation. In addition to being limited in supply, the burning of coal as an energy source releases sulfur dioxide into the atmosphere, where it causes to the formation of acid rain. As a result of the government's decreasing the amount of sulfur dioxide levels, coal is losing popularity as an energy source. The world's population is growing, and the number of industrialized countries is increasing. Whereas in the past a relatively small predictable group of nations competed for fossil fuels, both competition and demand have significantly increased in recent years. There was a time when electrical systems in homes were only required to power such items as lamps, ovens, and television. When today society and technology place a much greater demand on energy production. Scientists and engineers are engaged in ongoing research to develop alternative energy sources, innovative methods for meeting the world's energy demands to reduce the dependence on traditional, nonrenewable resources, now there have been other ways to produce energy which is very good but each way has a disadvantage.
Solar Energy: The sun is the greatest source of energy available on planet Earth and it comes for free and it is very efficient . Solar energy is already a proven technology that is easy in construction and therefore easy to transport and...
