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

more than enough energy to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun’s energy and make it useable. Solar Energy is the energy from the Sun. The Sun is a big ball of heat and light resulting from nuclear fusion at its core. The nuclear reaction releases energy that travels outward to the surface of the Sun. Along the way to the surface the energy transforms so that by the time it is released it is primarily light energy. The two major

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

Energy drinks should be regulated due to the fact that they cause health problems and the consumer is not aware because there are minimal‚ if any‚ labels. They claim to have some nutritional value in them said to give a “quick burst of energy.” In today’s market‚ there are so many different types of energy drinks that teenagers consume like Monster and Red Bull. Within these drinks there are numerous ingredients that may lead to some health risks. It has been requested from the Food and Drug Administration

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

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear
