ENERGY EFFICIENCY FACTS
Energy consumed by homes tripled from 1950 to 2006. U.S. currently imports about two-thirds of the oil it consumes and 69 percent of this oil is used for transportation. However, 2.9 billion gallons of fuel per year are wasted by vehicles sitting in traffic. The U.S. generates 5.8 billion metric tons of CO2 in 2006 or 45% of the world’s green house gas emissions with only one-third of the world’s cars. CO2 emissions in un-developing countries will increase at a rate three times that of developed countries.
In 1950, the average household used 1,584 kilowatt hours per year and today, the average use is 11,840 kilowatt hours a year. Global electricity usage will rise by 36.2 percent by 2030. The U.S. average homes use of electricity is consumed by: lights and appliances (24%), refrigeration (5%), air conditioning (16%), personal computers (1.5%) and television (7.4%).
In 1950, the average household used 6 quadrillion BTUs per year and today, the average use is plus 21 quadrillion BTUs. The average U.S. household spends (+/-) $1,500 a year on utility bills with much of the energy wasted. Furnace accounts for 47% and 17% for water heater usage.
70% of the world’s water consumption per day goes toward agriculture. By 2025, 2.8 billion people in 48 countries will live in water stress areas. In the U.S., two-thirds of the water used goes toward irrigation versus 40% today and within six years, 36 states are expected to be strapped for water. The average U.S. household uses 150 gallons of water per person per day. (The energy required to distribute and treat water is the country’s greatest consumer of electricity... enough to power 5 million households per day.)
Generate 21% of CO2 emissions, the atmospheric concentration of gas, altering all ecosystems. World forests are getting reduced on average by 60,000 kilometers per year and deforestation accounts for one-fifth of annual CO2 emissions.
