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.

Although it is proving controversial, wind power is becoming rapidly more popular these days. This type of renewable energy comes from wind farms, huge areas of land which are given over to dozens of wind turbines. Because of the relatively small amount of energy produced by wind turbines, they require a great deal of space to produce a worthwhile amount of power. This can severely damage local environments, however, they can also be placed its sea in certain cases.

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.

Solar power is another technology which is becoming increasingly popular. This, of course, comes from sunlight and is reflected upon solar panels which then convert the light into electrical power. These days, in a number of countries, solar power is becoming quite popular in people’s homes where people are having their own solar panels installed. This is because, not only do they produce electricity for the household, it is usually the case that any excess electricity generated by your solar panel, can be sold back into the great. Not only does this help to save the planet, but it also helps you to save some money too.

Another form of renewable energy is biofuel, which is derived from recently dead biological material, as opposed to fossil fuels which come from organic matter left by creatures and plant life long dead. The technology that utilises biofuel is rapidly becoming more popular, with a number of flexible fuel cars starting to appear on the market.

Renewable energy can also come from tapping directly to the natural heat sources of the planet. This type of renewable energy is called geothermal energy. The kind of power stations which are required to convert the earth’s heat into energy is, unfortunately rather expensive, although quite economical to run.

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.
