Welcome To Best Renewable Energy Sources
Renewable energy has become very popular. With renewable energy we mean energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy sources are environmentally friendly, being clean sources of energy.
Solar energy is what most people associate with renewable energy. Photovoltaic cells, the first one was created back in 1953, have been used for quite some time for generating energy. Nowadays, solar panels are mature technology and prices have come down. But photovoltaic cells are not they only way of converting sun rays into energy. Solar thermal collectors can also be used. Rather than converting solar energy into electricity like solar cells, thermal collectors capture sunshine and use it for heating purposes.
Wind energy has become very popular lately. Windmills have been used to generate mechanical energy. But the modern windmill is used to generate electricity. The blades of the windmill rotate and drive a generator which produce electricity.
Hydropower is also classified as renewable energy, this may sound a little bit odd since dams can often cause big changes to the environment. Of course, it is not necessary to build huge dams in order to take advantage of hydropower. The most common from of hydropower works in the same way as a windmill but instead of wind, water is used to drive a generator.
