Human being progress has its visible causes on the earth and environment. Unfortunately, the more it has helped in improving life, further it has caused damage to the planet. Subsequent todecades of industrialization and the destruction of nature, people are now getting more and more disturbed about it. There are number of individuals who have dedicated their lives and lifestyles to this new kind of green revolution. It is said that this revolution started from straightforward concepts such as planting trees and reprocessing. Nowadays there are a dozens of mobile home manufacturer who are making completely prefabricated houses for an absolutely greener life.

An extremely chief contributor of pollution and global warming is the fuel. Typically, industries made use of fossil fuels which are non- renewable and creates a lot of pollution when burned. Today, the planet is looking for renewable resources that can renew them with time. Although each resource we make use of replenishes with time, for renewable resources, this process has to be as fast as they are made use of. The energy generated by these resources is called renewable energy. There are five main types of renewable energies.

Solar Energy

Being the biggest and universal source of energy, the sun is one of the main preferred green energy sources. One nice thing regarding solar energy is that it does not decrease with its use. Indeed, the global warming stats recommend that it is only going to increase with time. Maybe if we start to use this resource as a substitute of burning trees and coal, global warming will be very much decrease. Photoelectric cells are special types of cells which transforms the solar energy into electrical energy.

Wind Energy

Like the sun, the wind is also every where. The only dissimilarity is that its speed may vary all round the year. Nevertheless, there are many regions where there is always enough wind to start the wind turbines all year round. These grounds are now being transformed into wind farms where the force of wind is controlled and transformed into electrical energy.

Hydropower

Hydropower is the most used renewable energy around the globe. Most of the electricity that comes into our houses is produced by dams. The cause is that the run out of water is strong for a longer period of year, and the efficiency of these dams is greater than solar panels and wind turbine. However, there are some environmental concerns with this kind of energy also, for example, the loss of aquatic life.

Geothermal Energy

It is a comparatively newer kid of energy. A number of green loving people are making use of geothermal energy to use their domestic appliances. It is mainly the heat from under the earth’s surface that is changed into electrical energy.

Biomass fuel

Contrasting fossil fuels, this type of fuel is inexpensive and easily renewable. Biomass fuel is a name certain to any fuel that is cultivated out of the earth and burned. These can be non-eatable portion of crops, alcohol from fruits and vegetables or throw aways from human and animals. Biomass fuel is probably to finish the dependency on oil.
