Solar energy & other alternative greener sources of energy

Category: Business

Scientists and environmentalists in the UK and worldwide are promoting the use of solar energy and other greener sources of energy to improve the environment and to reduce the dependence on oil and fossil fuels. Solar energy is 100% pollution free. Sunlight can be captured in the form of usable heat or it can be converted into electricity using solar or photovoltaic cells. Studies reveal that by using only 1% of its total land, the UK can harness all of its solar needs. The benefits of using solar energy are therefore tremendous. Wind energy accounts for only 0.1 percent of the world’s electricity demand. But this form of energy is going to increase rapidly as wind is one of the purest forms of energy and is capable of generating energy as long as the wind blows. Bio energy or fuel is another green energy source. It involves releasing of the chemical energy stored in organic matter like wood, crops, and animal waste. These materials are burned directly to produce heat Coal plays a very important role in meeting the World’s energy needs, ever since it was used in the Industrial Revolution. The fact that coal is available in abundance makes it very affordable but it releases sulphur and nitrogen and on combining with the water it forms acid rain. Burning coal also produced carbon dioxide that is one of the main gases that contributes to global warming. Make use of green, alternative sources of energy and save your environment from further degradation. Since the alternative energy sources are cost-effective, you can also save a lot of your money in paying electricity bills by relying upon solar energy or biomass or wind energy to meet your energy needs.
