From 2003 to 2007 the US relied on fossil fuels in the form of coal, natural gas, and petroleum to supply about 85% of its energy needs, while renewables such as wind and solar, accounted for about 7% of US energy needs.

The charts below detail US energy consumption by source (coal, natural gas, nuclear, wind, etc.) and by state. They also provide state population numbers to put each state's energy use into a national perspective. For example, in Chart II the population of Texas (23,367,534) is about 8% of the US population, while its energy use (11,744.4 trillion Btu) is about 11.8% of the US total.

Footnotes:
1. The totals for biomass include the following categories: biofuels, waste (landfill gas, municipal solid waste, and other biomass), and wood and other wood derived fuels.
2. In addition to wind and solar (photovoltaic and solar thermal), this category also included geothermal energy and net imports of electricity.
3. A positive number in this category indicates that more electricity came into the state than went out of the state during the year; a negative number means that more electricity left the state than the amount that came in (all the percentages in this column take into account the amount of energy lost during the conversion of fuels - such as the conversion of coal to electricity).

IV. Btu Conversion Chart

The US Energy Information Agency (EIA) defines a Btu as "[t]he quantity of heat required to raise the temperature of 1 pound of liquid water by 1 degree Fahrenheit at the temperature at which water has its greatest density (approximately 39 degrees Fahrenheit). According to the EIA "[e]nergy consumption is expressed in Btu to allow for consumption comparisons among fuels that are measured in different units."

For example, renewables such as wind and solar power produce electricity. Electricity is normally measured in a unit called the kilowatthour (kWh) while petroleum (oil) and other liquid fuels are often measured in gallons.

1. Electricity: 1 kilowatthour = 3,421 Btu

2. Natural Gas: 1 cubic foot = 1,028 Btu

3. Oil: One quadrillion Btu (1015) = 172 million barrels of oil

4. Wood: 1 cord (128 cubic feet) = 20 million Btu
