Energy is nearly as critical to survival as water and food, and, in fact, helps deliver these essentials. Electricity and fuels are fundamental to commerce, health, education, culture and recreation We are at a crucial point in how we make and use energy.

All energy on the Earth originates from the Sun. The Sun provides more energy to the Earth in one hour than all of the energy consumed by humans in an entire year (National Academy of Sciences). Power of the Sun Source: NOAA National Renewable Energy Laboratory Innovation for Our Energy Future
Excellent solar potential shown in dark red, with areas of less potential in lighter colors Displays a 12-month cycle In the U.S., the Southwest has the highest solar resource. But even orange and yellow areas have solar potential Global Solar Resources Source: NASA SSE v.6/NREL National Renewable Energy Laboratory Innovation for Our Energy Future
Dark colors show highest wind resources. Includes wind resources 50 nautical miles off coastlines. In the U.S., the Great Plains contains the highest wind energy potential Global Wind Resources Source: PNL 1981 & 1987/NREL National Renewable Energy Laboratory Innovation for Our Energy Future
Actual and projected population growth 1950 to 2050. Each dot represents 1 million people. In 2001, the world population was approximately 6.1 billion. By 2050, the world population is projected to be 9.4 billion people. Modernization in countries like China and India driving up energy demand.

World energy demand at record level and consumption is projected to increase by 50% from 2005 to 2030 The U.S. consumes approximately 100 Quads (quadrillion Btu) of energy per year, 25% of the world’s total. Non-OECD countries’ energy consumption (and CO2 emissions) projected to soon outpace OECD countries, principally driven by growth in China and India. World Energy Consumption per Capita Source: IEA/UN/NREL National Renewable Energy Laboratory Innovation for Our Energy Future
Energy intensity describes energy use per dollar of economic activity. Darker colors indicating higher energy intensity. Energy Intensity = Energy/GDP. The U.S. is energy efficient relative to our GDP. This is a function of both efficient energy use and the growth of a service-based economy over heavy industry. Russia’s energy/GDP is high due to economic decline and heavy industry. Energy Consumption per GDP Source: EIA National Renewable Energy Laboratory Innovation for Our Energy Future
Current energy mix for selected countries for fossil, nuclear, and renewable energy. Chart sizes proportional to each country’s energy consumption Most nations consume more fossil energy Global population increases and use of fossil fuels is linked In next 20 years, use of coal and natural gas to generate electricity will increase more than other sources Increasing reliance on fossil fuels results in higher energy prices, increased security risks, and higher concentrations of greenhouse gases in the atmosphere.
