are two primary methods for generating electricity from water. One method uses the energy potential of trapped water in dams in a more sophisticated version of the water wheel‚ and the other method of generating electricity is to capture energy from ocean waves. Electricity generated from water is entirely renewable‚ sinccete water is an abundant natural resource First method:When a dam is used to generate energy‚ tunnels are installed in the dam when it is built. These tunnels are lined with turbines

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

Energy conservation refers to reducing energy consumption through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service.[1] For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services

Renewable Energy INTRODUCTION/BACKGROUND Renewable energy is a new concept to some people but in actuality it has been around and talked about for many years. What it is is energy that comes from a source that is not depleted when used‚ and can be replenished. Some of these sources are wind‚ rain and sunlight. Renewable energy can replace the common standard fuels humans use in the generation of electricity‚ hot water and heating‚ and motor fuels (“How Solar Energy Works
