Expert Answer
No source of energy can be perfectly pollution free but biomass energy, hydro electric energy, wind energy, geothermal energy and solar energy are almost pollution free. If fossil fuel is allowed to burn in presence of excess of oxygen, the pollution produced can be reduced to a good extent.
