Wind Vs. Solar in the Race for India’s Energy Future This article compares the present and future potential for energy production from wind and solar sources in India and presents a brief analysis of future trends in these two energy technologies. Introduction India is undergoing an energy crisis. 53% of the country’s current power needs come from coal. This highly polluting source of energy is bound to run out someday. Compared to the West‚ India’s energy consumption is growing at break-neck

and bluster‚ prodded by the restless wind. Ski resorts don’t like to talk about wind–or storms in general—because it scares away the tourists‚ who somehow forget that winter is messy‚ cold‚ and wild‚ as if snow were laid down softly each night like a blanket over a sleeping baby. But wind is a fact of life in the mountains‚ as much a part of the weather as snow itself‚ and those who grumble about it or say it does nothing but blow overlook the fact that the wind gives as much as it takes. It can seem

decided to choose this topic because wind turbines is one of the answer against the global warming‚ it is a completely renewable source of energy. When it is installed‚ running cost are lower than many other electrical systems. While running‚ wind power do not produce carbon dioxide. However‚ all structure have an impact on the environment. Many people complain about the damage to local eco-system‚ to the visual impact as well as the noise that produce. Wind turbine seems to be clean when they

It is still being debated to on exactly when did the ancestor of our species began to walk on two legs. One hypothesis relies on a 6-7 million year old skull of Sahelanthropus tchadensis. The skull was discovered in the Djurab Desert in Chad. Since only the skull was discovered‚ it is still unclear on how Sahelanthropus tchadensis fits in our evolutionary

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush‚ who ran his entire Euclid Avenue mansion off of one for 20 years‚ which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn’t rise a great deal afterwards‚ this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose

Background/History on the Wind Power Industry The wind power industry first developed in Iran around 200 B.C. The first windmills were vertical axis wind turbines‚ which were used for pumping water and grinding whole grains for food consumption. The Chinese‚ Romans and Afghans all used windmills around this time for similar use. In the 13th century Holland started developing large horizontal axis windmills. These four-blade windmills were larger‚ carried more torque and wind speed and could do more
