s) Only areas class 3 or higher are suited to wind turbine construction Another problem with total reliance on wind energy would be the unreliable nature of the wind; a still day could render anyone depending on the turbines powerless. However, a good option is to keep undesirable but more reliable power generation at the ready for when the wind tapers down. A nation such as Denmark who is already producing about 20% of their electric use through wind power could keep coal or gas plants at standby; because the majority ... ... middle of paper ... ...198 Watts. 3452198 watts / 833.33 watts =~ 4143 The one turbine has the ability to power over 4100 houses in the United States and saves about two tons of CO2 emission every hour the wind is blowing at the above speed.

However, these kinds of energy resources have limits. Therefore, at the some point in the future, people will not be able to produce energy from those resources. Renewable energies, including wind power, are remarkable resources for many countries such as Denmark and Japan. However, the different historical backgrounds of wind power created differences between Denmark and Japan: Denmark is one of the highest producers and consumers of wind power while Japan is not; however, despite some disadvantages such as destroying scenery, Japan should use more wind power because it is good for environment, it is renewable, and it reduces damage from disaster. When looking back each history of wind energy in Denmark and Japan, there is the time lag to begin to develop wind power between the nations.

Solar Energy and the Energy Crisis Abstract The energy crisis is a major problem in the United States. Solar energy can help alleviate this problem. Enough solar panels to fulfill the energy needs of the entire United States would take up 27,347 km2 and cost almost 17 trillion dollars. Therefore, although there is enough space for all those solar panels, the economic cost is far too great. However, solar power can be phased in gradually.
Wind Power Energy production causes more pollution than any other industry in the country. Currently, nearly all of the electricity produced in the United States is generated by fossil fuel plants, nuclear plants, and hydroelectric plants. The build-up in the atmosphere of carbon dioxide and other greenhouse gases produced by the burning of fossil fuels now threatens far-reaching climate change. In addition to global warming, conventional methods of electricity generation release the gases responsible for acid rain, sulfur dioxide and nitrogen oxide. In order to prevent further degradation of our environment and successfully transition to a sustainable society, we must change our current patterns of production and consumption.
Hydrogen: the Fuel of the Future? The Problem: For years, United States citizens have been using natural gases and oils to power their cars. While doing so we have also been polluting our environment, making ourselves dependant on other regions of the world, and depleting our oil reserves. Rory Sporrows of “Geographical” wrote, “The car is responsible for combusting eight million barrels of oil every day, contributing to nearly a quarter of total global greenhouse emissions and causing major increases in bronchial diseases like asthma and emphysema.” (2001) Oil is not a renewable resource. One day it will run out.

Abstract With nonrenewable energy sources such as fossil fuels being quickly depleted as humans require more energy in the daily lives of modern society, renewable energy sources are becoming increasingly popular. For example, many energy sources such as wind power, solar power, and water power are being used throughout the world. Among these, hydroelectricity, the harnessing of energy from moving water and one form of renewable energy, is an efficient, economical, and nonpolluting alternative to fossil fuels with the potential to provide a larger percentage of world energy in the future. Introduction Hydroelectric energy is generated from moving water and is currently the largest source of renewable energy in the world. (Union of Concerned Scientists, 2005) As shown in Figure 1, small and large hydroelectric energy together constituted over 63% of all renewable energy used worldwide in 2005.
