* The washing machine uses an average of about 41 liters of water per load, while The new models, high-efficiency machines use less wash 28 gallons of water per load. (EPA, 2008) * The home of a suburban family uses at least 30 percent of their water outdoors for irrigation. Some experts estimate that more than 50 percent of landscape water use is lost through evaporation or runoff caused by excess water! Consider installing a drip irrigation system to water your lawn and garden. These systems use water from 20 to 50 percent less than the sprinkler systems on the ground. They are also much more efficient than sprinklers because it is not lost in the wind, runoff and evaporation. (EPA, 2008) Principle of world demand Power
* your browser for electricity will double between 2000 and 2030. The greatest increase will occur in developing countries, and faster growth will occur in people’s homes. * Electricity (Worldwatch Institute, 2007) production is the main cause of industrial air pollution States States, and is responsible for 40 percent of carbon emissions that contribute to the nation to global climate change. (Worldwatch Institute, 2007) * The majority of cases, 35 percent of energy from coal in a power plant becomes electricity. The remaining two thirds is lost as waste heat, benefiting no one and often affect surrounding ecosystems. (Worldwatch Institute, 2007) Heating * Nearly half the energy the average home is used for heating. (EIA, 2007) * poorly sealed / caulked windows can account for up to 25% of the total losses to heat a home. (Environment Canada, 2007) * Lighting consumes up to 34 percent of electricity in the United States. (Worldwatch Institute, 2007) * The bulbs, compact fluorescent bulbs (CFLs) are an alternative to incandescent bulbs Low Power – produce the same amount of light, use a third of the electricity and last up to ten times longer. (Worldwatch Institute, 2007) * If every household replaced its light bulbs light of the most frequently used bulbs with CFLs, electricity use for lighting could be reduced by half. (Worldwatch Institute, 2007) * When electricity is produced from coal, each fluorescent bulb used prevents 1,300 pounds (about 600 kilograms) of CO2 emissions and 20 pounds of carbon dioxide sulfur is pumped into the atmosphere. (* Worldwatch Institute, 2007) Appliances and Electronics If you need to warm up or defrost small amounts of food, use a microwave instead of saving energy. Microwave ovens use of energy about 50 percent less than conventional ovens do. (California Energy Commission, 2006)
* A refrigerator built 20 years ago the energy consumed 70% more than models of high energy efficiency today. * Today (Environment Canada, 2007) dishwashers are energy about 95% more efficient than those sold in 1972 – the old dishwasher may cost you more money on energy bills of which would have to buy a new one.
