What Exactly is Green Energy?

As the finite resource of fossil fuel which includes coal and oil becomes limited in satisfying the present energy demand, alternative energy sources are now sprouting promising new technologies that can reduce our dependency on fossil fuels. One of this so called alternative energy sources is green energy.

Also called renewable energy, green energy can be harvested out from sunlight, wind and water. This means that we don’t need to prospect new sites as the sources of green energy can be found everywhere and is considered to be of an infinite source as they are naturally replenished. In effect, green energy can be used in remote areas where electricity is limited or not yet available.  Compared to traditional energy sources, what is good with green energy is it creates little pollution and has very little impact in our environment.

There are several types of green energy being used nowadays. The most common type is solar power which captures sunlight turning it into electricity using photovoltaic cells embedded in solar panels. The most common usage of solar energy is used to power small hand held gadgets like mobile phones, tablets and flashlight to powering up basic household appliances. Big companies are now investing to energize small rural centers, communities and neighborhoods using solar energy by installing fields of gigantic solar panels.

Some places on earth experiences stronger winds where wind energy can be harvested by turning turbines as a result of strong wind. The principle behind this renewable energy source is the stronger the wind, the more turbines turn thereby creating more energy. Wind turbines are usually installed in locations where you can capture the strongest wind like in high altitude places and areas near the beach. 

About seventy five percent of the earth’s surface is covered by water and as these bodies of water constantly moves, energy can be harvested and produced. Hydroelectric power is generated using electric turbine being propelled as the water moves. A good example of hydroelectric power is the generation of energy from the force of water moving through a dam.

Aside from the water’s major occupancy on the earth’s surface, beneath its surface lie massive amounts of thermal energy created from the heating of the earth’s crust and mantle. Excess thermal energy is being emitted out of the earth’s surface where this can be harvested and turned into geothermal energy. Usually, the precursor of geothermal power is the presence of hot springs as it indicates hot thermal spews. The energy from the earth’s subterrain can produce limitless amounts of energy compared to the combined energy of all coal power plants in the world keeping aside the fact that they are protested in some countries because of their non eco-friendly characteristics.

In the field of agriculture, its waste is now being converted to produce energy. Biomass energy can now be produced by the burning of wood waste, agricultural throw-aways and other materials that are combustible. On the other hand, instead of burning biomass to produce energy, these materials are being processed to produce biofuel. Famous processed biofuels are ethanol and biodiesel that is projected to carry out 25% of the worlds demand for fuel by 2050.

The future of green energy is bright as it has the potential to replace fossil fuel, if not, supplement it. Modern research promises new technologies that can lower the cost of green energy production while placing the ability to produce energy in our hands and not from utility companies that uses fossil fuel.
