In a few decades from now, oil deposits throughout the world would be waning out, a sign which is being manifested in form of rising oil prices. 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.
Biomass fuel is being used for running biofuel 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 aircrafts using biofuels. 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 utilised, but still a few aspects need review and reconsideration.
The present day scenario presents a lot of prospects for utilising alternative fuel sources for production of electricity and running of cars. With active participation of the governments and proactive role of technology companies, there will surely be enough means of producing energy from renewable sources. It is only a matter of time and sincere efforts from the government and companies before alternate energy sources will become as common as petroleum products have been till now.
