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.

Hydroelectricity is derived from water. Examples of this include water wheels and water mills. One of the best things about hydroelectric power, is that it is effective and relatively cheap to run. These days and supplies 19% of the electricity and the whole world. There are a number of things that can supply hydroelectricity such as tidal power and wave power.

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, home 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 home solar power with more and more people installing solar panels in their homes.

These 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.
