Plants as Sources of Energy
Wood was the main source of energy in the United States and the rest of the world until the mid-1800s, and biomass continues to be a major source of energy in much of the developing world. In modern societies, solid biomass continues to be used directly as a combustible fuel, producing 10–20 MJ·kg −1 of heat.

Sources of Energy: A Comparison | CFR Education
There are three main categories of energy sources: fossil fuel, alternative, and renewable. Renewable is sometimes, but not always, included under alternative. Fossil Fuels: Petroleum, Coal, and Natural Gas. Fossil fuels formed over millions of years ago as dead plants and animals were subjected to extreme heat and pressure in the earth's crust.

17.4: Consequences of Nuclear Energy
Furthermore, nuclear power plants are more reliable than any other source, with a capacity factor of 93.5% (figure (PageIndex{b})). Capacity is the amount of electricity a generator can produce when it's running at full blast, and the capacity factor is a measure of how often a plant is running at maximum power.
