What is Renewable Energy?

Renewable energy can take many different forms and depends on natural sources, such as sunlight,for it to be able to work. Factors, such as hydroelectric power and wind, causes the earth surface to heat up, which in return, causes air to move as wind, as well as allow precipitation to form, once the air is lifted.

Since the direct conversion of sunlight, makes up solar energy, some structures need to be implemented to be able to support it. These include either solar panels or collectors.

One example of renewable energy is biomass which is sunlight that is contained within plants. There are also many types that do not depend on sunlight, which are referred to as geothermal energy. This type of energy is a result of any radioactive decay, located inside the crust, which combines with the heat that gets accreted in the earth. The same goes for tidal energy, which is also converted from gravitational energy.

Different Types of Renewable Energy

There are several types of renewable energy, all of which includes wind power, solar energy, biomass, hydroelectric energy, hydrogen, as well as fuel cells, geothermal power, and more types of energy.

Wind Power –All movement in the atmosphere, gets driven by the differences of temperatures in the earth’s surface. It is usually due to a change in temperature, in the presence of sunlight. Wind energy is a popular type of renewable energy and is used to generate electricity, by pumping water. It thus also requires adequate coverage, to be able to produce large amounts of energy.
Solar Energy – As one of the most popular types of renewable energies, solar energy works by relying on nuclear fusion power, which is generated from either the sun or the core of the earth. Many homes today, have a solar panel attached to their roof, to create their source of electricity. It is considered a far better, and natural method, to generate electricity.
Biomass Energy –This type of energy is derived from the energy from plants. Energy, in the form of biomass, is commonly used, globally. The most popular biomass energy gets created when burning trees, which is used for daily human activities. Unfortunately, biomass contributes to an unhealthy source of air, as it adds to carbon dioxide gases in the atmosphere.
Hydroelectric Energy –By using the gravitational potential of water that is elevated, almost like condensation with water, except by using seawater, it is one source of renewable energy that is not 100% renewable. It is still, however, a method that is used to create renewable energy, by making use of hydroelectric dams, daily.
Hydrogen cells – Also not considered entirely renewable, hydrogen, as well as fuel cells are a very helpful resource, as there are endless amounts available thereof. Not only can it be burned as fuel, which is generally used in a vehicle, but the clean-burning fuel could potentially reduce pollution in cities. It can also be used to create fuel cells, like batteries.
Geothermal Power –Also recognised as renewable energy, geothermal power is created by heat, all from radioactive decay. It causes the geothermal gradient to increase, to generate more electricity.
