Energy Storage Will Soon Replace Simple Cycle Combustion Turbine Peaker Plants. Power grids need extra generating capacity to work properly. For example, about 20 percent of New York Stateâs generation fleet runs less than 250 hours a year. Because they donât run much, âpeaker plantsâ are by design the cheapest and least efficient fossil generators.
The largest source of carbon dioxide (CO2) emissions are currently  from electric generation through the combustion of fossil fuels.  Particularly the burning of coal is mos â¦ t pollutive, as compared to  oil or natural gas generation.
Sulfur dioxide mostly comes from the burning of coal or oil in power plants. It also comes from factories that make chemicals, paper, or fuel. Like nitrogen dioxide, sulfur dioxide reacts in the atmosphere to form acid rain and particles.ulfur dioxide mostly comes from the burning of coal or oil in power plants.
