How can alternative sources of energy be harnessed effectively? Written by Jill (Huimei ZHOU) Nowadays‚ there are more and more alternative sources of energy for people to use. But in order to harness these alternative sources of energy effectively‚ different countries take different actions based on their own natural resources. This essay will show that how to make full use of energy from different countries’ viewpoints. Undenied‚ many years ago‚ a lot of countries just use the fossil fuels

Renewable energy is energy that originates from natural sources‚ which is a continuing and nonpolluting energy that is replenished due to its perpetual natural motion. These sources are commonly solar‚ geothermal‚ wind and tidal energies. Comparing different countries’ use of renewable energies -- in Portugal this year‚ close to 45 percent of its electricity will come from renewable energy sources (Rosenthal‚ 2010). This compared to 10.1 percent in the United States (U.S. Energy Administration

Alternative Energy Alternative Energy Our environment is ever changing so it would only make sense that our climate will change also. Researchers believe that the changes in our climate are directly related to certain types of energy. Energy plays an important role in many aspects of our lives. For example‚ we use electricity for lighting‚ heating‚ and cooling. We use fuel for transportation‚ heating‚ and cooking. Our energy production and use are connected with many other aspects of modern

The energy that is used today comes from fossil fuels‚ which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar‚ hydroelectric‚ geothermal and wind energies can be used‚ to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide electricity for homes and businesses. Hydroelectric energy can

How can alternative sources of energy be harnessed effectively? In modern society‚ an increasing number of people pay more attention to how to make use of alternative sources of energy effectively.With the development of economy and society‚ existing energy sources have been hard to meet the increasing market demands. Therefore‚ alternative energies become more and more important because they are directly related to the future economic and social development. Therefore‚ this essay will discuss

to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However‚ we are now realizing the problems that are created by using fossil fuels to generate energy. These problems are so great that they will force humans to find an alternative source of energy in order to avoid the inevitable

1st Draft Nowadays‚ There are many alternative sources of energy for people to use. In the past people make fire by cracking two pieces of flint causing sparks against dry tinder or fleece. But now people use technology for their needed. People have used more than 90% of fuels‚ such as oil‚ coal and natural gas to produce electricity. These things are non-renewable. The more we use these fuel it will decreases everyday. So we have to find another

Alternative Energy for Future Nowadays the most common energy resources come from Fossil Fuel‚ which according to research it shows that more of 85% of all energy that is consumed in the United States. It takes millions of years for the Fossil Fuel to actually develop and ready to be used‚ and the main concern of Fossil Fuel is that it cannot be consumed over and over again or reused. Through this analysis it can be assumed that because it takes millions of years for the fossil fuel to develop‚
