Important Facts About Renewable Energy

The term renewable energy does not only refer to one but to different types of alternative sources of energy. In principle, it means energy that is able to replenish itself indefinitely. Unlike non-renewable energy sources like fossil fuels, renewable sources of energy can be regenerated or replenished indefinitely.As an example, the sun is used for solar power and the wind is used to turn turbines. However, the sun and the wind won’t get depleted as they will remain to be present for as long as our planet exists. Therefore, there is no need to get worried about renewable sources of energy being depleted. All these energy sources are known to be environmentally friendly and you can play a part in protecting the earth’s environment by using one.The types of renewable energy that can be harnessed are quite diverse. Of these energy types, solar energy, wind energy and geothermal energy can be used separately to provide power to your home. You will notice that some homes use solar panels to generate electricity and heat, while there are also homes that utilize geothermal pumps for heating.With solar energy you can get electricity or hot water to heat the house. The sun’s rays are converted into energy using photovoltaic panels: PV, it stands for PhotoVoltaic – the name “Voltaic” came from Alessandro Volta an Italian physicist known for some invention connected to energy power, is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that produce the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of cells containing a photovoltaic material.The future of the entire world, however, depends on the use of these resources to produce electricity and other forms of energy on a global scale. In order to accomplish this, there are now various types of renewable energy plants being constructed around the world. The most numerous of these are hydroelectric power stations which are built near rivers and other places with flowing water.Wind energy plants, meanwhile, are becoming popular all over the world. Wind farms are being built where 20 or more wind mills will be put up in order to generate maximum output from the wind power plant. There are still other forms of renewable energy being used these days. Geothermal plants are constructed in many areas of the globe, while wave and tidal energy are gathered in ocean coasts in other countries.
