Renewable Energy – How It Can Help Save The World

05.27.2009 · Posted in Technology Articles

While we are rapidly starting to run out of non renewable energy sources, renewable energy relies on natural sources that effectively last forever. We do not have to worry about running out of wind, water, sunlight and the natural geothermal heat of the planet.nnPresently, approximately 20% of all the energy in the world comes from renewable sources. The most popular is simply the burning of wood to provide us with warmth and light and the second most common form of renewable energy comes on the rapidly increasing industry of hydroelectricity which is currently supplying approximately three per cent of the world’s electrical power.nnWind power, of course, is wind that is converted into electricity by way of wind turbines. This technology has however proven controversial due to the fact that it requires an enormous amount of land to build enough windmills to generate a satisfactory amount of electricity. These wind farms are not only unsightly, but they can be damaging to the local environment. Fortunately, however, they can also be placed in the sea.nnEnergy from water is called hydroelectricity. This kind of energy is created by way of water wheels and water mills and dams. The biggest advantage of a hydroelectric power, is that it is relatively cheap to produce and also brings us a lot of power, currently supplying the world with 19% of its electricity. Hydroelectric power can also come from waves and the force of the tides.nnBiofuel is also emerging as another reliable form of the renewable energy. In contrast of fossil fuels, which are derived from long dead organic matter, biofuel comes from recently dead biological objects. Today, there are even a number of cars which have a dual fuel system, with the ability to run on certain types of biofuel.nnFinally, geothermal energy is another form of a highly effective renewable energy. This type of energy comes directly from tapping into the heat of the planet itself. Unfortunately building geothermal energy power stations is not cheap, but they are cheap to run and they produce a lot of electricity.nnCurrently the market for renewable energy is rapidly expanding with many organizations capitalizing on the growing industry. industry is one of the fastest growing, increasing at an amazing rate of 30% per year. Domestic solar power is also becoming more and more popular.nnThese are worrying times for the world today. With the rapidly growing population, comes a far higher need for energy and we are rapidly running out of non Renewable Sources of energy. However, it gives us hope to know that the industry of renewable energy is rapidly increasing and at last governments and individuals are starting to do something about the problem.
