Energy

  1. Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.g
  2. Refrigerators in the U.S. consume about the same energy as 25 large power plants produce each year.e
  3. There are two basic groups of energy: renewable energy (biomass, geothermal, solar, water, and wind power) and nonrenewable (fossil fuels coal, oil, natural gas, nuclear). Three quarters of the world’s energy is generated by burning fossil fuels.h

  26. American hospitals are some of the most energy-intense buildings on the planet.h
  27. Electric utilities are the largest source of greenhouse gas in America.h
  28. In 2008, the Wall Street Journal reported that transportation fuel consumption in the U.S. would grow from 150 billion gallons annually in 2020 to over 250 billion gallons by the middle of this century. Researchers hypothesize that we would have to export trillions of dollars to oil producing countries, which would compromise our currency, our economy, and our environment.h
  29. Lighting currently accounts for about 20% of U.S. electricity consumption.h
  30. James Hansen, director of NASA’s Goddard Institute for Space Studies, has argued, “Coal is the single greatest threat to civilization and all life on our planet.” In America, burning coal releases more CO2 in the air than all cars and trucks combined.h
  31. Playstation 3 A PlayStation 3 uses more energy than a refrigerator
  32. In the average home, 75% of the electricity used to power home electronics is consumed while the products are turned off. The average desktop computer idles at 80 watts, while the average laptop idles at 20 watts. A Sony PlayStation 3 uses about 200 watts and nearly as much when idle. Idle power consumes more electricity than all the solar panels in America combined.h
  33. On a hot summer afternoon, California consumes the entire output of two large nuclear reactors pumping water.h
  34. One ceiling fixture can use $2,000 to $5,000 of electricity over its useful life.h
