Energy Nothing can live without energy. People‚ animals and plants need energy to live and machines need energy to work. Today‚ most of the energy we use still comes from fossil fuels like coal‚ oil and gas‚ which have been formed underground over millions of years. We called these non-renewable forms of energy because they can only be used once. Because of this‚ we need to reduce our use of non-renewable fuel and use more renewable forms of energy like that from the sun‚ wind or geothermal

Nuclear energy… Boon or Bane ? Nuclear energy? Nowadays these two words are always sticking on the society’s mouth‚ but do they know the actual meaning of it? Nuclear energy is basically defined as the energy released by the reaction within the nuclei‚ as in nuclear fission or fusion. The core reason of using nuclear energy is to generate electric power to satisfy human needs. Usage of the nuclear power plant as an energy generator came together with several boons and banes. As quoted by the

Renewable energy is energy from natural resources such as sunlight‚ wind‚ rain‚ tides‚ and geothermal heat‚ these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five

Energy Outline A. Benefits Of Solar Energy • Does not release green house gases • Production of solar energy does not produce smoke‚ gas‚ or any other chemical byproducts • Solar energy contributes to about 4 percent of the world’s electricity • Italy’s Montalto di Castro solar park: o good example of how solar contributes to the decrease in emissions o Decreases the carbon emissions by about 20‚000 tons per year compared to fossil fuel energy production. • Money! o Except for the initial

Definition of Wind Energy “Wind Energy - Energy received from the movement of the wind across the earth. This energy is a result of the heating of our oceans‚ earth‚ and atmosphere by the sun. Turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power.” The German physicist Albert Betz calculated in 1919 the possible maximum amount of energy that can be extracted out of wind energy. He came to the result of 59.3% that can be extracted and named this

Alternative Energy Alternative Energy whether used for transportation or utilities such as generating electricity for home or business is a very significant subject going on right now because of the benefits it would provide for us‚ such as environmental‚ economic‚ job security and energy security. I believe alternative energy would be beneficial to our society‚ especially if it is used in transport; there is many other better‚ leaner and reusable energy sources out there‚ for example fuel for

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Energy Management and Audit Report 1) Introduction For over the past few years‚ the planet Earth is being damaged by human activities. Buildings play a major role in that. They contribute to approximately 40% of the greenhouse gas emissions globally. Over the past 30 years‚ 10% of the ice burgs have been melted due to the rising temperature of Earth. The rise in temperature is caused by greenhouse gas. Therefore‚ green building is important today. Green building has both positive and negative

Energy[edit] Aralvaimozhy railway station in Kanyakumari District with a view of wind farm Starting from the second quarter of 2010‚ the total energy demand in Tamil Nadu state is increasing exponentially[citation needed] and the state government is helpless to cut off power supply to an vast extent to the consumers. The complete state (except Chennai city‚ the capital) suffers a power cut for more than 11 hours a day. The city of Chennai only has 2 hours of power cuts a day.[citation needed]

Wind Energy Wind energy is a free‚ renewable resource‚ so no matter how much is used today‚ there will still be the same supply in the future. Because the wind energy is also the source of the clean‚ and non- polluting‚ electricity. Wind energy is friendly to the surrounding environment‚ as no fossil fuels were to generate electricity from wind energy. Wind Energy is a viable industry that has become energy source. The energy generated from wind is clean and efficient. The wind energy industry
