The natural process with very little environmental impact such as anaerobic digestion, wind power, biomass power, solar power, and power from a geothermal source is called green energy.
The funding of green energy through suppliers and the extension of quantities of green energy by customers through the power corporations leads to a green economy. An economy in line with the United Nations which aims at negating environmental impact and ecological detriment is called a green economy. It is closely connected with ecological economic science, however, it contains a lot of politically applied focus. Greenhouse emissions are the direct cause of human intervention which causes global warming and climate change.
