Global Warming
FIGHTING AGAINST GLOBAL WARMING
The biggest cause of global warming is the carbon dioxide released when fossil fuels like oil and coal are burned for energy. So when you save energy, you fight global warming (and save money, of course). Here are some easy steps you can take:
Choose an efficient vehicle:A car that gets 20 miles per gallon will emit about 50 tons of carbon dioxide over its lifetime. A car getting 40 mpg will emit half that much. When buying your next car, pick the least-polluting, most efficient vehicle that meets your needs. Maybe it's an innovative hybrid that combines a gasoline engine with electric motors (and never needs to be plugged in). Or maybe it's a wagon instead of an SUV. And over the average lifetime of an American car, a 40-mpg car will save roughly $3,000 in fuel costs compared with a 20-mpg car, so compare fuel economy performance before you buy.
Drive less.When possible, choose alternatives to driving (public transport, biking, walking), and bundle your errands together so you'll make fewer trips.
Buy energy-efficient appliances.Use your consumer power when buying appliances by shopping for energy-efficient models. You may spend a little more up front, but you'll save a lot on electricity, and you'll reduce pollution produced by power plants. Look for the Energy Star label, which identifies the most efficient appliances. You can also use the Energy Guide labels to compare the efficiency of specific models. Remember that refrigerators consume the most electricity in the home. Today's refrigerators consume less than one-fourth the energy of models built 30 years ago, so an upgrade could mean huge energy savings for your household.
Replace your light bulbs with compact fluorescent bulbs.While compact fluorescents are initially more expensive than the incandescent bulbs most people use, they last 10 times as long. What's more, a compact fluorescent will lower your energy bills by about $15 a year, and by more than $60 during its life. It will also keep half a ton of carbon dioxide out of the air.
