What are the effects of electrical energy generation on environment? Are fossil fuels a good way of electric energy generation?

Explanation

The energy obtained through the fossil fuels as well as nuclear energy can cause degradation of the environment. If such energy sources are used, they can cause harm to the environment.
(1) The burning of fossil fuels air pollution. The incomplete combustion of fossil fuels cause release of carbon monoxide. Some more toxic gases and soot particles cause various respiratory diseases. The carbon dioxide produced is creating global warming and climate change. The nitrigen dioxide released through burning is responsible for acid rains.
(2) Fossil fuels are limited. They are getting fast depleted. It has taken millions of years for the fossil fuels to form. The exploration of such fuels also cause environmental degradation and marine pollution too.
(3) In production of nuclear energy, there is a great risk of accidents. The safe disposal of nuclear waste is also a problem.
(4) Hydroelectric power from water reservoirs, wind power from wind, solar energy from sun and electricity from biofuels are eco-friendly alternatives.
