6. Write two advantages of electric energy.
Answer ⤵️
Advantage: Multiple Electricity Sources
According to the U.S. Energy Information Administration, fossil fuels such as natural gas, coal and petroleum produced 67 percent of the nation's electricity in 2013. In addition to obtaining electricity from nuclear power plants, some people can get hydropower, or electricity that comes when you harness the energy of falling or running water. If you live in a windy area or one that receives lots of sun, wind or solar power might be an attractive energy option. It's also possible to generate electricity by using heat from below Earth's surface to produce steam that turns turbines. People also generate electricity from biomass, which is material from sources such as wood, fuel crops and agricultural wastes.
Disadvantage: Unwanted Side Effects
Power plants that burn biomass release sulfur dioxide and nitrogen oxides, two undesirable pollutants, into the air. Power plants that burn fossil fuel pump carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas that causes Earth's temperature to rise. Nuclear power plants must find ways to dispose of radioactive waste safely. Building dams to create hydropower plants can affect wildlife and natural resources adversely.
