Abstract
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

These
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
