electricity, chemicals and transportation fuels. Biomass energy, thus is the use of biomass for any
of these purposes.

Geothermal
Sun is not the only source for renewable energy. Geothermal energy accounts for another
source for renewable energy whereby it taps the Earth's internal heat for a variety of uses, such as
electric power production and the cooling and heating of the buildings.

Hydrogen
Hydrogen is commonly found all around, especially in water as well as organic
compounds. Hydrogen is the most abundant element of the Earth. Hydrogen is the main element
which is required to produce energy. Therefore, it should be kept in mind that it’s not an energy
source itself, but it is merely a way to save and transport energy. Thus, hydrogen is also called as
energy carrier.

Ocean
Ocean is another source which can be used for producing thermal energy by using the
heat from sun and mechanical energy from the waves and tides. There is a lot of information
available online if you wish to see how ocean can be used as a source for energy.
