Write the short note on= Electrical energy generation & environment
Answers
Although electricity is a clean and relatively safe form of energy when it is used, the generation and transmission of electricity affects the environment. Nearly all types of electric power plants have an effect on the environment, but some power plants have larger effects than others.
Electricity generation mainly produced from fossil fuels (coal, natural gas, and petroleum), materials that come from plants (biomass), and municipal and industrial wastes. The substances that occur in combustion gases when these fuels are burned include
Carbon dioxide (CO2)
Carbon monoxide (CO)
Sulfur dioxide (SO2)
Nitrogen oxides (NOx)
Particulate matter (PM)
Heavy metals such as mercury
In the United States, about 64% of total electricity generation in 2017 was produced from fossil fuels (coal, natural gas, and petroleum), materials that come from plants (biomass), and municipal and industrial wastes. The substances that occur in combustion gases when these fuels are burned include
Carbon dioxide (CO2)
Carbon monoxide (CO)

Nearly all combustion byproducts have negative effects on the environment and human health, Some power plants also produce liquid and solid wastes. Nuclear power plant produces many different types of waste.
