mean by sustainable energy? Sustainable energy is about using energy wisely and using energy generated from clean sources and clean technologies. Wise energy use is the first step to ensuring we have sustainable energy for present and future generations. Being efficient with our energy will reduce our household and business energy bills‚ reduce the amount of energy we need to produce in the first place and cut energy related greenhouse pollution. So sustainable energy is not just about

Selection of Topic: Energy Crisis is a shortfall in or interruption to the provision of energy supplies. The planet is progressively marching towards a serious electric energy crisis‚ owing to an escalating desire of electric energy becoming greater than its supply. We have always accepted that the energy we make use of each day is not unrestricted‚ still we take it for granted. Coal‚ petroleum‚ electrical power‚ even water has inadequate availability. Nevertheless‚ we have not taken sufficient

Cinddy Solar energy Today‚ people make full use of solar energy and it benefits them a lot‚ especially in Spain and China. Due to their favorable conditions‚ solar energy has good practicality. It is much more convenient to use solar energy as people’s main energy resources than other renewable energy. The government gives financial support of solar energy which largely stimulates the growth of renewable energy. In addition‚ solar energy has a huge amount of influence on people’s life such

release of nuclear energy occurs when the nuclei of atoms are changed. Hydrogen and uranium are two kinds of matter used to produce nuclear energy. In a nuclear reaction‚ the tremendous binding energy inside a hydrogen or uranium nucleus is released. Nuclear energy is released during atomic fission‚ when uranium nuclei are split. It is also released during fusion‚ when hydrogen nuclei combine to form a helium nucleus. In fission and fusion‚ nuclear energy produces thermal energy‚ which is given

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

Energy is the fuel that runs the engine of the world economy. Believe it or not our need for energy is not primarily to run economies but intrinsically to create order in the world. Wind energy Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been used for hundreds of years for sailing‚ grinding grain‚ and for irrigation. Wind energy systems convert this kinetic energy to more useful forms of power. Wind energy systems for irrigation and milling have been

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is an

Energy Resources and their Uses in Producing Electricity Renewable energy is energy drawn from natural processes that are restored quicker than they are used up‚ some renewable energy resources are biomass‚ food‚ wind‚ waves‚ flowing water‚ solar and geothermal. The sun however‚ is known to be the ultimate energy resource since almost all energy resources originate from the sun’s energy. This is possible according to the law of conservation of energy which states that energy can’t be destroyed

Introduction Energy conservation is very important in to not only the community but also the world. By conserving energy you will not only be helping your bottom line by reducing you energy bills but you will also be helping the world ’s environment. An average savings of up to forty percent can be achieved though a properly implemented energy conservation plan Renewable vs. Nonrenewable Resources Renewable energy sources are sources that are self-sustaining. Nonrenewable energy sources are commonly

Research Essay Energy Crisis Fossil fuels and Nuclear power plants are extremely dangerous to the environment. They pollute the very atmosphere we breathe and they’re extremely expensive. It emits large amounts of toxins and carbon dioxide into the air‚ not only hurting humans but also the crops we grow. They also assist the cause global warming. “A catastrophic human’s effect of burning fossil fuels and nuclear waste is global warming. They emit carbon dioxide and other greenhouse gases‚ which
