Understanding the sources of renewable energy

The sources of energy can be broadly categorized into two main categories depending on their source and their impact on nature. These are renewable and nonrenewable energy.Renewable energy is generated from various natural resources and do not emit carbon compounds in the environmentLet us further look at the sources of renewable energy and what are their uses are.Solar Energy:
Energy that is derived from sunís heat and radiation is known as solar energy. It is categorised as renewable energy because the source is abundant and harnessing the same do not reduces its heat or radiation and it do not impact environment because solar energy doesnít produce carbon emissions. This is the most common source of energy and can be used specially during day time to produce electricity to supply the demands in hot days. The following technologies has be developed to use solar energy

Photovoltaic Systems
Generating electricity for solar energy
Solar water heaters
Passive Solar Heating and Daylighting
Space heating and cooling using solar energy
Using sunís heat in industrial and commercial processes

Wind power:

The concept of wind is known to everyone and the wind cycle is not the new topic to understand. As long as the sun is there the wind is generated. The kinetic energy generated from wind can be transferred into electrical energy by using wind turbines. These turbines are usually set up on high altitudes to use the wind pressure. This source of energy is also termed as renewable as the wind is a free source and by harnessing the same, they do not contributes in air or water pollution

The wind energy is harnessed since centuries for uses like:

Pumping water
Grinding grain

Generating electricity

Water Energy:

Hydropower is the energy generated from flowing water. The gravitational energy from the water is released as it falls. The flow can be in terms of melting snow or streams and rivers.The energy from the water is harnessed by creating dams on the rivers.
The energy is generated from the water stored in reservoir at the dams. The water is released with force to generate the energy which can be used to generate electricity. This is a renewable source of energy as the source is natural and free once the dam is constructed.

Biomass energy:

Energy generated from natural wastes is called as biomass energy. The sources can be:
Scrap lumber
Forest debris
Certain crops

Food waste during processing and after use

It is also considered renewable energy because the waste will always generate and more of manages forests that will replenish the environment and their organic wastes.

Geothermal energy: Geothermal energy is the heat from the Earth. Itís clean and sustainable. The geothermal energy is generated from the shallow ground, hot water natural geysers, hot rocks or the molten rocks available in the form of magna. The technologies are developed to harness the geothermal energy. It can be used for:

Geothermal Electricity

Space heating and cooling

Food preparation

Hot spring bathing and spas




Industrial processes.
