A Brief Introduction to Renewable Energy
With environmental concerns as they are today, renewable energy is enjoying a time of heightened interest. Renewable energy can come from a number of sources such as wind, water, sunlight and heat from geothermal sources. Today, approximately 20% of the energy in the world comes from renewable sources. While most of this comes from burning wood a very large amount also comes from hydroelectricity.
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.
One of the most common forms of renewable energy is hydroelectricity, which comes from water. One of the main advantages of hydroelectric power, is that it produces a great deal of electricity and is not particularly costly to run. Hydroelectricity can come from dams, water mills and water wheels. Of a number of other things that can help to supply hydroelectric power, waves and tides.
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.
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.
Currently 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.
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.
