1. ENERGY CONSERVATION Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service.
2. Even though energy conservation reduces energy services, it can result in increased environmental quality When we conserve energy resources, our nation can enjoy cleaner air and a healthier environment, and we can help protect the climate by reducing green house gases national security Energy efficiency enhances national security. Many experts believe that our civilizations dependence on fossil fuels represents the greatest threat human kind has ever faced. Conserving energy supports national security by prolonging the availability of finite domestic energy resources, reducing the environmental impacts that are weakening our planets ability to support us, and reducing our dependence on imported resources, such as natural gas and oil, from socially, politically and economically unstable, foreign regimes. A distributed and diverse energy supply system may be our greatest defense against the health, economic, social and security threats to our country. Treated as a resource, negawatts not only reduce the need to import our energy supplies and build new power plants but help to create a diversified energy resource base. Needs For Conservation 3. Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing fluorescent lights or natural skylights reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs. Compact fluorescent lights use one-third the energy of incandescent lights and may last 6 to 10 times longer. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production processes  or by application of commonly accepted methods to reduce energy losses. Finacial security 4. Conservation of energy helps to reduce the problem of energy crisis. Solar energy also Helps in control Energy crisis. Control energy crisis 5. Use renewable source of energy like solar energy,wind energy,geothermal energy,etc Avoid unnessessory use of energy Control war and use energy in enhancing new technology. Methods for conservation 6. Future energy technology In the future, civilization will be forced to research and develop alternative energy sources. Our current rate of fossil fuel usage will lead to an energy crisis this century. In order to survive the energy crisis many companies in the energy industry are inventing new ways to extract energy from renewable sources. While the rate of development is slow, mainstream awareness and government pressures are growing. 7. Electric carar Solar-Powered Keyboards
