Quiz 13: Energy

Environmental Science

Wind power is clean and renewable source of energy. It helps to clean the environment and reduce the dependence on the present sources of energy. Wind power energy is a great net energy. Net energy means that the wastage of energy in very less. The energy produced and the energy consumed to run gives us the net energy. In the wind power turbine the wind energy is great to use. Presently we are using the energy which is generated from coal, nuclear plants, and diesel. This energy is not lasting long because of increasing pollution because of this energy. The power plant is situated away from the cities because these cause pollution and also dangerous. Hence, wind power is great to use and safe to use. The major advantage of the wind power is that it is clean to use and have no effects on the environment.

(a) Calculate the gasoline consumed by vehicle per year. img (b) The cost of one liter gasoline is 80 cents. Therefore, total cost of the gasoline img (c) Calculate the gasoline consumed annually by complete fleet. img The above calculation shows the various effects on gasoline consumption for the given efficiency of car.

The United States Department of Energy makes the four favorable sites for the wind energy and these sites are North Dakota, South Dakota, Kansas, and Texas. The wind energy plants in United States have generated enough energy that could replace the 3200 kilometers of coal train. Number of jobs in the United States has increased significantly from 2004 to 2010.
