COAL -- A Fossil Fuel - ei.lehigh.edu

carbon and hydrocarbons. It is the most abundant fossil fuel produced in the United States. Coal is a nonrenewable energy source because it takes millions of years to create. The energy in coal comes from the energy stored by plants that lived hundreds of millions of years ago, when the earth was partly covered with swampy forests.

How much coal is required to run a 100-watt light bulb 24 ...

That is a pretty big pile of coal, but let's look at what else was produced to power that light bulb. A typical 500 megawatt coal power plant produces 3.5 billion kWh per year. That is enough energy for 4 million of our light bulbs to operate year round. To produce this amount of electrical energy, the plant burns 1.43 million tons of coal.

Coal and Air Pollution | Union of Concerned Scientists

Coal has long been a reliable source of American energy, but it comes with tremendous costs because it is incredibly dirty. The same chemistry that enables coal to produce energy—the breaking down of carbon molecules—also produces a number of profoundly harmful environmental impacts and pollutants that harm public health.
