Energy Basics. An energy system converts primary energy resources like fossil fuels or wind into energy services. Energy services are what humans care about, like hot showers and cold beverages. There are energy losses each
Renewable energy, explained. Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels. By Christina Nunez.
Energy use can be divided many dfferent ways but the most common is through the the end product — either electricity; themal energy, which is heating/cooling (including hot water); or transportation.
Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained
6 · Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Learn more about energy in this article.
Searching for the facts about how the United States uses energy? The National Academies, advisers to the nation on science, engineering, and medicine, provides objective background information about how energy is used at home, in commercial space,
Energy is a word which tends to be used a lot in everyday life. Though it is often used quite loosely, it does have a very specific physical meaning. Energy is a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms.

How the United States uses energy. Many sources of energy are used in homes, businesses, industry, and power plants and to travel and transport goods. These energy sources are used by five main energy use sectors: The residential sector includes homes and apartments.
This article focuses on the quantity of energy we consume — looking at total energy and electricity consumption; how countries compare when we look at this per person; and how energy consumption is changing over time.
