"Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/ cooling, transportation, and rural (off-grid) energy services." [Renewable energy.

The donut chart example "Renewable energy" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Pie Charts solutiton of the Graphs and Charts area in ConceptDraw Solution Park.

This divided bar diagram sample shows U.S. primary energy consumption by source and sector in 2015. It was designed using data from the chart in the webpage "U.S. Energy Facts Explained, Consumption & Production" on the website of the U.S. Energy Information Administration.
"Americans use many types of energy
Petroleum, natural gas, coal, renewable energy, and nuclear electric power are primary sources of energy. Electricity is a secondary energy source that is generated from primary sources of energy.
Energy sources are measured in different physical units: liquid fuels in barrels or gallons, natural gas in cubic feet, coal in short tons, and electricity in kilowatts and kilowatthours. In the United States, British thermal units (Btu), a measure of heat energy, is commonly used for comparing different types of energy to each other. In 2015, total U.S. primary energy consumption was about 97.7 quadrillion (1015, or one thousand trillion) Btu."

"Consumption of energy resources, (e.g. turning on a light) requires resources and has an effect on the environment. Many electric power plants burn coal, oil or natural gas in order to generate electricity for energy needs. While burning these fossil fuels produces a readily available and instantaneous supply of electricity, it also generates air pollutants including carbon dioxide (CO2), sulfur dioxide and trioxide (SOx) and nitrogen oxides (NOx). Carbon dioxide is an important greenhouse gas which is thought to be responsible for some fraction of the rapid increase in global warming seen especially in the temperature records in the 20th century, as compared with tens of thousands of years worth of temperature records which can be read from ice cores taken in Arctic regions. Burning fossil fuels for electricity generation also releases trace metals such as beryllium, cadmium, chromium, copper, manganese, mercury, nickel, and silver into the environment, which also act as pollutants.
The large-scale use of renewable energy technologies would "greatly mitigate or eliminate a wide range of environmental and human health impacts of energy use". Renewable energy technologies include biofuels, solar heating and cooling, hydroelectric power, solar power, and wind power. Energy conservation and the efficient use of energy would also help."
