Sources of Energy: A Comparison | CFR Education

To evaluate the options available, understanding fundamental facts about what types of energy are available and what trade-offs each presents is helpful. There are three main categories of energy sources: fossil fuel, alternative, and renewable. Renewable is sometimes, but not always, included under alternative.

Renewable Energy | Department of Energy

Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.

What is Renewable Energy?

Renewable energy is energy that is generated from natural processes that are continuously replenished. This includes sunlight, geothermal heat, wind, tides, water, and various forms of biomass. This energy cannot be exhausted and is constantly renewed. Alternative energy is a term used for an energy source that is an alternative to using …

What is energy? explained

The stored chemical energy in coal or natural gas and the kinetic energy of water flowing in rivers can be converted to electrical energy, which can be converted to light and heat. Energy sources are renewable or nonrenewable. There are many different sources of energy, but they can all be divided into two categories:

Renewable Energy

Renewable energy is the fastest-growing energy source globally and in the United States. Globally: About 11.2 percent of the energy consumed globally for heating, power, and transportation came from modern renewables in 2019 (i.e., biomass, geothermal, solar, hydro, wind, and biofuels), up from 8.7 percent a decade prior (see figure below).

Solar Energy

Solar energy complements other renewable sources of energy, such as wind or hydroelectric energy. Homes or businesses that install successful solar panels can actually produce excess electricity. These homeowners or businessowners can sell energy back to the electric provider, reducing or even eliminating power bills.
