Green energy is a powerful and quick fix remedy to combat global warming by tackling its primary cause i.e. greenhouse gas emissions. Traditional energy sources, such as coal, oil, and natural gas, release large amounts of carbon dioxide (CO?) and other harmful pollutants during combustion. These emissions accumulate heat, leads to rising global temperatures and several climate consequences. Green energy is primarily comes from natural resources and is generated using renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power including tidal power.
