Renewable energy is a form of energy that can be generated from a number of different natural resources. These renewable resources come from wind, water, rain, sunlight and geothermal heat. Currently around 20 per cent of the world's energy comes from the renewable energy sources. The vast majority of this comes from burning wood. The second most common form of renewable energy that is in use in the world today comes from hydroelectricity which provides three per cent of the world's electricity.
Presently, 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.
Wind 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.
Energy 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.
Biofuel 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.
Finally, 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.
When it comes to renewable energy, the industry is growing quickly and many companies are starting to capitalise on the increasing demand for environmentally friendly energy solutions. One of the fastest growing industries with regards to renewable energy is that of solar power with more and more people installing solar panels in their homes.
In these worrying times of environmental destruction coupled with the rapidly growing worldwide population, it does give us some hope when governments and individuals and companies are starting to be really aware of the problem and start producing more environmentally friendly solutions. Hopefully, we can expect to see further technological advancement in the near future and the rapidly increasing use of renewable energy sources. It is the only hope for the future of the planet.
