Our Current Energy consumption
—In 2008, fossil fuels provided almost 85% of the energy used in the United States. —7% of our total energy use comes from renewable energy sources, such as wind, solar, and hydropower. —40% of U.S. energy from all sources is used to generate electricity. —Experts predict a 26% increase in the demand for electricity in the United States by 2030. —By the year 2020, world energy consumption is projected to increase by 50 percent, or an additional 207 quadrillion BTUs. —If the global consumption of nonrenewable energy sources remains constant, the world’s available fossil fuel reserves will be consumed in 104 years
