WIND ENERGY Long time ago‚ ancient mariners used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today‚ more and more people are using wind turbines to wring electricity from the breeze. Over the past decade‚ wind turbine use has increased at more than 25 percent a year. Still‚ it only provides a small fraction of the world ’s energy. Therefore‚ wind power or wind energy is the energy extracted from wind using wind turbines to produce electrical

"Electrical Energy Consumption" Sustainability and electricity Where does electricity come from? Most people use electricity and see it as something that is infinite and probably don’t give a second thought about its source. This is quite understandable‚ considering electricity looks clean; it doesn’t cause any noise pollution or direct air pollution. The fact is that most electricity is produced by burning coal‚ and the use of nuclear power plants. Simply stated‚ the more electricity used‚

The term pollution can be applied when the composition of something has been modified by the presence of one or more substances that either it cannot be used for a specific purpose or it is less suitable for that use than it was in its natural state. Nature pollutes water with leaves that fall off the trees and decay‚ animal waste‚ and oil seepages

Energy Crisis in Pakistan “What does ‘LOL’ stand for in Pakistan? ‘Lots-of-Loadshedding’.” [Introduction] Pakistan is energy-deficient. How can one imagine an active and prosperous human being short on blood? Life is hard without sufficient blood running up and down the veins‚ pumped by the heart round the clock. Pakistan has failed to contain its energy crisis; failing to increase supply proportionately and conserving demand. In 1980s‚ it met 86% of its demand; come 2000s‚ situation is getting

Energy is needed by the body to stay alive‚ grow‚ keep warm and move around. Energy is provided by food and drink. It comes from the fat‚ carbohydrate‚ protein and alcohol the diet contains. Energy requirements vary from one individual to the next‚ depending on factors such as age‚ sex‚ body composition and physical activity level. Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest)‚ the thermic effect of food (TEF‚ the energy required

Energy Workers of the World Energy workers have an enormous impact on our world. It’s hard to believe that not even 80 years ago we were without electricity. As technology advances‚ it has become apparently easier for man to live comfortably. People do not realize how important these workers are and what life would be like without them. Almost everything we do‚ each and everyday‚ involves something to do with what an energy worker has pursued. Some of these things include lights‚ computers‚ televisions

Solar Energy: Powering Our Future Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy‚ has become expensive‚ environmentally harmful‚ and finite. With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050. The need to find a viable source of energy within
