What is the function of clean energy?

Some points on function of clean energy are:

• Clean energy power plants do not produce fly ash or soot because electricity generation does not involve solid fuel combustion.
• Electric output from clean energy sources avoids flue gas emissions that are characteristic of coal and oil power stations.
• Clean energy generation does not require emission control equipment such as scrubbers or electrostatic precipitators used for combustion exhaust.
