What are practical ways to reduce global warming ?

Question

And where can I find case studies about the same.

Answer 1

Turn the Air conditioning off.

Use less electricity.

Drive a small car or take public transportation.

Eat locally grown food.

Live in a small house

buy less stuff, keep what you have till' it's worn out.

Answer 2

The most critical way to reduce global warming is to humanely reduce the number of people on the planet.  All other measures mentioned previously will fail if the number of humans continues to rise without limit.

One woman, one child for two generations.

This does not imply that the other measures are not important.  They are, but they are not a substitute for population control.

Answer 3

Change Five Lights

Replace your five most frequently used lights or the bulbs in them with ones that have earned the Energy Star and you’ll use less energy, which means less pollution from power plants. Your household will also be saving about 700 pounds of carbon dioxide a year and save $90 a year in energy costs (If every household in the country did it -- we would save a trillion pounds of greenhouse gases.)

About half the energy we use in our homes goes to heating and cooling. Changing air filters annually, having your system checked annually and useing a programmable thermostat are all easy things you can do. Just by using a programmable thermostat, you can save about 1,800 pounds of carbon dioxide a year

If you replace your current washing machine with a low-energy, low-water-use machine you will be able to reduce your carbon dioxide emissions by 440 pounds per year. For even more savings wash your laundry in warm or cold water, instead of hot. That will bring in a reduction of carbon dioxide emissions of about 500 pounds per year.

Reduce and Recycle

Reducing your garbage by 25 percent will reduce carbon dioxide emissions by 1,000 pounds per year. Recycle aluminum cans, glass bottles, plastic, cardboard and newspapers can reduce your home's carbon dioxide emissions by 850 pounds per year.

Don't Give Energy Away

If you caulk and weather-strip around doors and windows to plug up leaks you can reduce carbon dioxide emissions by 1,700 pounds per year

Take the Green Way

Leave your car at home two days a week (walk, bike, take public transit or telecommute) and you can reduce your carbon dioxide emissions by 1,590 pounds per year.

Buy Products That Have Earned the Energy Star

Over 40 different kind of products now carry the Energy Star -- the government-backed symbol for energy efficiency -- including lighting, home electronics, heating and cooling equipment and appliances. With Energy Star products you can save 30 percent on your energy bills (about $450 a year). For information on high efficiency appliances and other products, visit the Energy Star Web site (www.energystar.gov).

Be a Turnoff

Turn off your TV, video player, stereo and computer when you aren't using them. Turn off your lights when you don't need them and you start saving within a minute or two. Prevent "phantom" energy losses by plugging these devices into a power strip and turning the power strip off when the devices are not in use

Keep Your Water Heater Cozy

For a water heater more than five years old, wrapping it in an insulating jacket will result in a 1,000 pounds per year reduction of carbon dioxide emissions. Keep your water heater thermostat no higher than 120 degrees F and you can reduce carbon dioxide emissions by 550 pounds per year.
