Energy Facts
 
  • A one-kilowatt PV system each year prevents:
    • 1,800 lbs. of coal from being mined
    • 3,600 lbs. of CO2 from entering the atmosphere
    • 5.3 lbs. of mercury from contaminating the atmosphere
    • 1,260 gallons of water from being polluted

     

  • Within 15 years, renewable energy could be generating enough electricity to power 40 million homes and offset 70 days of oil imports.
    •   

  • Replacing one incandescent light bulb with an energy-saving compact fluorescent bulb means 1,000 pounds less carbon dioxide is emitted to the atmosphere and an average of $67 dollars is saved on energy costs over the bulb's lifetime. (U.S. Environmental Protection Agency and Alliance to Save Energy)
    •  

  • Just by using "off the shelf" energy-efficient technologies available today, we could cut the cost of heating, cooling, and lighting our homes and workplaces by up to 80%. (U.S. Department of Energy and Maryland Energy Administration)
     
  •  
  • By taking appropriate energy-saving measures the United States can have an energy system that reduces costs by $530 per household per year and reduces global warming pollutant emissions to 10 percent below 1990 levels. (Energy Innovations report)
                  
  • The earth receives more energy from the sun in just one hour than the world uses in a whole year.
  • Per capita Canada consumes the most energy in the world, the United Sates ranks second.
  • America has 5 percent of the world's population and consumes 26 percent of the world's energy.
  • World energy consumption is expected to increase 40% to 50% by the year 2020.
  • Developing countries use 30% of global energy. Economic growth in China and India will rapidly increase that percentage in the next 10 years.
  • The World Bank estimates that investments of $1 trillion will be needed in this decade and upwards of $4 trillion during the next 30 years to meet developing countries' electricity needs alone.
  • Global mix of fuels—fossil fuels (78%), nuclear (4%), renewables (18%)
  • America uses about 15 times more energy per person than does the typical developing country.
  • In 2010 U.S. residents consumed an average of 12,133 kilowatt-hours of electricity each, almost nine times greater than the average for the rest of the world.
  • Residential appliances, including heating and cooling equipment consume 90% of all energy used in the U.S. residential sector.
  • Total U.S. residential energy consumption is projected to increase 17 percent by 2015. (U.S. Energy Information Administration)
  • Solar Energy demand has grown at about 30% per annum over the past 15 years.
  • Photovoltaic prices have declined on average 4% per annum over the past 15 years.
  • On average, 16 million tons of carbon dioxide are emitted into the atmosphere every 24 hours by human use worldwide. (U.S. Department of Energy)
  • The United States is the world's largest single emitter of carbon dioxide, accounting for 23 percent of energy-related carbon emissions worldwide. (U.S. Department of Energy)
  • Carbon emissions in North America have increased 38 percent since 1970. They are expected to grow another 31 percent by the year 2020. (U.S. Department of Energy)
  • An average of 23,000 pounds of carbon dioxide are emitted annually by each American home. The equivalent of two cars driven 20,000 miles each. (U.S. Environmental Protection Agency)
  • About 81 tons of mercury are emitted into the atmosphere each year as a result of electric power generation from coal. Mercury is the most toxic heavy metal in existence. (U.S. Environmental Protection Agency)
  • Approximately 30,000 lives are cut short in the U.S. each year due to pollution from electricity production. (ABT Associates study)
  • The United States consumes about 17 million barrels of oil per day, of which nearly two-thirds is used for transportation.
  • The United States imports more than seven million barrels of oil per day.
  • Americans use a billion gallons of motor oil a year, 350 million gallons of which end up polluting the environment. (Department of Energy and Maryland Energy Administration)
