Such escalations in the prices have brought various countries throughout the world to think about various other alternate energy sources. Countries like Spain, Japan, Germany, United States, etc have been actively researching and developing ways to harness renewable energy from sources such as wind, sun, water, geothermal, biomass fuel, etc. These efforts have produced results in various countries and they are gradually trying to lower their oil exports.
Governments throughout the world are targeting the alternative fuel sources for running their machines and creating electricity. By understanding how does solar power work, they are able to harness the solar energy to electrify cities. Biomass fuel is being used for running bio fuel cars. Besides lowering the consumption of oil, these alternative fuels for cars have lowered the carbon dioxide emission. In a few countries, buses are being run on fish oil. Waste cooking oil from restaurants is used to run the machines in parks and gaming stations. Even, there have been trial runs of aircraft using bio fuels. Some companies are coming up with engines for cars, which can run on alternative fuels for cars. Undoubtedly, renewable energy resources are being harnessed for various uses and such trysts have been successful. Encouraging signs are in plenty that alternate energy sources can be utilized, but still a few aspects need review and reconsideration.
