Recycling: Energy

The world's electricity demand is expected to double between 2000 and 2030. The greatest increase will occur in the developing world, and the most rapid growth will occur in people's homes. (Worldwatch Institute, 2007)

Electricity production is the leading cause of industrial air pollution in the United States, and is responsible for 40 percent of the nation's carbon emissions that contribute to global climate change. (Worldwatch Institute, 2007)

At most, 35 percent of coal's energy in a power plant converts to electricity. The remaining two thirds is lost as waste heat, benefiting no one and often harming surrounding ecosystems. (Worldwatch Institute, 2007)

Heating

Almost half of the average home's energy consumption is used for heating. (EIA, 2007)

Improperly sealed/caulked windows can account for up to 25% of total heat loss from a house. (Environment Canada, 2007)

Lighting

Lighting consumes up to 34 percent of electricity in the United States. (Worldwatch Institute, 2007)

Compact fluorescent light bulbs (CFLs) are an energy-saving alternative to incandescent bulbs — they produce the same amount of light, use one third of the electricity, and last up to ten times as long. (Worldwatch Institute, 2007)

If every household replaced its most often-used incandescent light bulbs with CFLs, electricity use for lighting could be cut in half. (Worldwatch Institute, 2007)

Where electricity is produced from coal, each fluorescent lightbulb used prevents 1,300 pounds (nearly 600 kilograms) of CO2 emissions and 20 pounds of sulfur dioxide from being 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 the stove to save energy. Microwave ovens use around 50 percent less energy than conventional ovens do. (California Energy Commission, 2006)

A refrigerator built 20 years ago uses 70% more energy than today's energy-efficient models. (Environment Canada, 2007)

Today's dishwashers are about 95% more energy-efficient than those bought in 1972 — your old dishwasher may be costing you more money in energy bills than it would take to buy a new one. (Environment Canada, 2007)

Many idle electronics — TVs, VCRs, DVD and CD players, cordless phones, microwaves — use energy even when switched off to keep display clocks lit and memory chips and remote controls working. Nationally, these energy “vampires” use 5 percent of our domestic energy and cost consumers more than $8 billion annually. (Alliance to Save Energy, 2005)
