Detailed explanation-1: -Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States. Fossil fuels are formed from the remains of ancient organisms. Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource.

Detailed explanation-2: -Coal is both the largest source of electricity generation and the largest single source of CO2 emissions, creating a unique challenge in transitioning to low-carbon energy systems.

Detailed explanation-3: -Because of its abundance, reliability and affordability, about 23.4% of the nation’s electricity is generated from coal, resulting in electricity costs that generally are 30% lower in states that rely upon coal for more than half of their electricity generation versus states that rely on other fuels.

Detailed explanation-4: -Fossil fuels are the largest sources of energy for electricity generation.

Detailed explanation-5: -Energy has been around since the dawn of time. The first source of energy was the sun, as it provided heat and light during the day. People rose and slept with the light, relied on wood and dung burning for heat, and water power to generate basic mills.
