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.
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.
It is common knowledge for people as to how does solar power work. Various researches are being carried out by countries to store enough energy from the sun, so that it can be utilized for the lighting up of cities. In the desert regions of United States, a few cities have been running on the solar power as alternate energy sources and there is no more electrical generation using coal. Rather, it is being done completely with the help of voltaic cells, which are able to capture the solar energy. Currently, it is required that more such set ups come up in the cities to store large amounts of energy.
Water and wind sources have also been utilized for the production of electricity, letting electrical generation using coal to become a thing of the past. Some of the perennial rivers are being used to drive huge turbines, which have created large amounts of electricity. Large windmills are being set up in some states of United States for the energy production. These have been the perfect examples of utilization of alternative fuel sources for lighting purpose. Good thing about these sources is that they are currently able to produce significant percentage of electricity.
Geothermal sources and biomass fuel have also created a flutter in the protection of environment. Although, these have been less than those of wind and solar power, yet they have the potential. Governments are encouraging the private companies for improvising their existing technologies by providing tax rebates and subsidies to these companies, which are involved in renewable energy production.
The present day scenario presents a lot of prospects for utilizing 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.
