What is green energy?

Green energy sources are the need of the hour. As natural energy resources get depleted and increased awareness of environmental issues, the need to go green has become imminent in recent years. What is green energy? The term green energy essentially refers to energy sources that provide maximum environmental benefits. The rising demand for green power has accelerated the transition towards cleaner and more sustainable power sources.

Types of green energy

For a better idea of what green energy is, it is prudent to look at a couple of clean and sustainable power generation methods. Solar, wind, and geothermal power generation methods are among the many clean energy sources that have made the transition to clean energy feasible.

Solar

This is undoubtedly the most popular green energy source. Different technologies are employed when tapping into this abundant resource, with photovoltaic and solar thermal power technologies being the most popular. Its abundance and ease of production make quite affordable.

Wind power

The use of wind power dates back to the cradle of humankind. The good thing about wind as a source of green energy is that it is relatively reliable and consistent. Initially, production of wind power required a substantial investment but this has since changed, and wind power has begun to set peak prices in the energy markets.

This is another green energy source that is considered sustainable and reliable as it relies on the heat from the inner parts of the earth. The only downside with geothermal is that it can only be harnessed in certain parts of the world – areas that have a history of tectonic movements like the rift valley and along continental boundaries.

From these three energy sources, it is evident that green energy sources pose minimal or no danger to the environment. Since the potential exists, nations have stepped up to accelerate the transition to sustainable or green power sources.
