Learn All About Renewable Energy Technology


What is Renewable Energy?

 Renewable energy is defined as the energy that is can be renewable naturally. It includes wind, rain, sunlight, geothermal heat, and tides. It originates from natural resources. There are many types of renewable energy that are growing very fast as people worldwide attempt to find ways to protect the environment.
Wind power is one of the fastest growing forms of renewable energy. It is used in Asia, Europe, and in the United States, and it is growing by 30 percent annually around the world. Windmills, or wind turbines are used to make electricity with this method. Multiple turbines are usually gathered together on a wind farm for this purpose.

Solar power is energy from the sun. Humans are currently using very little of this source of energy at the moment, but projections are that it will be used much more in the next 50 years. This power is capable at this moment of cooking, heating water and homes, and of many more uses that people depend on.
Biomass is plant material that is burned to release the energy stored in it from the sun. Some plants are grown specifically to be burned for energy and left over parts of plants are also used, such as twigs and small parts of tree trunks.

Geothermal energy is taken from the heat of the earth by pumping heat from the earth’s core. Hydro power is a form of energy obtained by capturing the energy from water. Dams are often used to produce electricity. Water is also being used to harness energy through the use of tidal wave and wave power around the world. The world’s first tidal power station is in Ireland, and it uses the speedy tidal flow to produce electricity. In the same way, the power of ocean waves is captured to produce energy. It is sometimes referred to as ocean energy.

Nuclear poweris a controversial form of energy and some sources consider it to be dangerous because of the potential for accidents that can cause harm to those living in the surrounding area.
A renewable energy source is considered to be a source that can be replenished at the same rate that it is used, as in the case of biomass when trees are planted to replace those that have been cut down. It can also be a continuing, self-renewing source such as energy from the ocean waves or from the sun. Alternative energy is the term used to describe any type of energy that is used to replace fossil fuels, which emit carbon dioxide that damages the earth’s ozone.
