Green energy generally refers to the resources of the Earth, such as sunshine, wind, rain, tide, wave, plants, algae and geothermal energy. The shared feature of these resources is that they are sustainable, and almost inexhaustible in supply.
Fossil fuels which are widely used around the Globe in the current age, such as petroleum, natural gas and coal, are limited resources which take millions of years to generate. It often involves penetrative mining at ecologically sensitive area to obtain such resources. Furthermore, fossil fuels tend to reduce upon using with emission of pollution, such as green house gas, that aggravates global warming.
In comparison to fossil fuels, “green energy” does little-to-none impact to the environment. Thanks to the rapid development of technology of generating sustainable energy, and remarkable reduction in the cost of material of solar panel and wind turbine generator, more households and communities than before in the world are now capable of generating power by themselves. “Green energy” can now even replace fossil fuels by supplying energy for daily life usage, such as heating, cooling and ventilation.
