7 Types Of Renewable Energy Sources

When we talk about renewable energy sources, we must understand that all sources of energy are

derived from nature. Both coal and petroleum are extracted from nature and can be used in the

way that they are for creating energy. However, crude oil is usually refined and processed into

gasoline, petroleum and other products before it is used. In the same way, coal has to be

converted into other forms of energy to use it fully. In that sense, the renewable sources are those

sources that can be used again and again as they are available in plenty and are not going to

perish anytime soon. These sources As of now, the consumption rates of coal and crude oil are

such that they will soon be depleted. From then on, our dependence

primary sources are converted to electricity, a secondary energy source, which flows through

power lines and other transmission infrastructure to your home and business.

7 Types of Renewable Energy Sources

1. Solar Energy

One of the first renewable sources of energy is sunlight. It is the reason why life on the planet

Earth has flourished and is the one truly renewable source of energy. About 70% of sunlight gets

reflected back into the space and we have only 30% of sunlight to meet up our energy demands.

Solar energy has become quite practical to use and many applications have created for it. First of

these is solar heaters. Whether it is industrial grade water heating or simple heating to cook

food, solar energy can be utilized quite easily. With the development of solar panels and

photovoltaic cells, it can also be used to create and store energy as needed.

Solar powered homes, cars and appliances are becoming common these days, as are solar farms

that provide electricity to areas that are not on the grid. Solar energy can also be used for

It does not cause any pollution, is

completely renewable and reduces our alliance on foreign countries for supply of oil and gas.

3. HydroElectric Energy

There is a large amount of kinetic energy stored in water. It is available for use when the rivers

and streams flow towards the oceans, and the potential becomes greater when they turn into

waterfalls. Hydroelectric energy is becoming a common source of electricity production in the

21st century.

Most dams that are being built have infrastructure that allows them to capture the energy from

the water. The kinetic energy of moving water is then used by hydropower plants to give

mechanical energy to turbines which in turn convert it to electrical energy through generators.

4. Geothermal Energy

Within the Earth, there is a great deal of energy trapped inside molten magma. All of this heat

transfers itself to the deep stores of water and air that flow through the Earth. In order to release

the heat and regulate the temperature of the core, the heated water and air are released through

vents, which are seen as holes in the crust of the Earth. They form another of the
