Global warming is a big problem please do your little bit to cut back and change the world.

1. Do not leave appliances on standbyUse the "on/off" function on the machine itself. A TV set that's switched on for 3 hours a day (the average time Europeans spend watching TV) and in standby mode during the remaining 21 hours uses about 40% of its energy in standby mode.

2. Move your fridge and freezerPlacing them next to the cooker or boiler consumes much more energy than if they were standing on their own. For example, if you put them in a hot cellar room where the room temperature is 30-35ºC, energy use is almost double and causes an extra 160kg of CO2 emissions for fridges per year and 320kg for freezers.

3. Cover your pots while cookingDoing so can save a lot of the energy needed for preparing the dish. Even better are pressure cookers and steamers: they can save around 70%!

4. Use the washing machine or dishwasher only when they are fullIf you need to use it when it is half full, then use the half-load or economy setting. There is also no need to set the temperatures high. Nowadays detergents are so efficient that they get your clothes and dishes clean at low temperatures.

5. Take a shower instead of a bathA shower takes up to four times less energy than a bath. To maximise the energy saving, avoid power showers and use low-flow showerheads, which are cheap and provide the same comfort.

6. Use less hot waterIt takes a lot of energy to heat water. You can use less hot water by installing a low flow showerhead (350 pounds of carbon dioxide saved per year) and washing your clothes in cold or warm water (500 pounds saved per year) instead of hot.

7. Be sure you’re recycling at homeYou can save 2,400 pounds of carbon dioxide a year by recycling half of the waste your household generates.

8. Buy intelligentlyOne bottle of 1.5l requires less energy and produces less waste than three bottles of 0.5l. As well, buy recycled paper products: it takes less 70 to 90% less energy to make recycled paper and it prevents the loss of forests worldwide.

9. Choose products that come with little packaging and buy refills when you canYou will also cut down on waste production and energy use... another help against global warming.

10. Reuse your shopping bagWhen shopping, it saves energy and waste to use a reusable bag instead of accepting a disposable one in each shop. Waste not only discharges CO2 and methane into the atmosphere, it can also pollute the air, groundwater and soil.

11. Reduce wasteMost products we buy cause greenhouse gas emissions in one or another way, e.g. during production and distribution. By taking your lunch in a reusable lunch box instead of a disposable one, you save the energy needed to produce new lunch boxes.

12. Plant a treeA single tree will absorb one ton of carbon dioxide over its lifetime. Trees are important because they provide shade and protection from the sun. Not only that they also provide a home to wild birds and animals.

13. Switch to green powerIn many areas, you can switch to energy generated by clean, renewable sources such as wind and solar. In some of these, you can even get refunds by government if you choose to switch to a clean energy producer, and you can also earn money by selling the energy you produce and don't use for yourself.

14. Eat less meatMethane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. Their grassy diet and multiple stomachs cause them to produce methane, which they exhale with every breath.

15. Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possibleAvoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year! Look for transit options in your area.

16. Start a carpool with your coworkers or classmatesSharing a ride with someone just 2 days a week will reduce your carbon dioxide emissions by 1,590 pounds a year. eRideShare.com runs a free service connecting north american commuters and travelers.

17. Drive carefully and do not waste fuelYou can reduce CO2 emissions by readjusting your driving style. Choose proper gears, do not abuse the gas pedal, use the engine brake instead of the pedal brake when possible and turn off your engine when your vehicle is motionless for more than one minute. By readjusting your driving style you can save money on both fuel and car mantainance.

18. Check your tires weekly to make sure they’re properly inflatedProper tire inflation can improve gas mileage by more than 3%. Since every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere, every increase in fuel efficiency makes a difference!

19. Try car sharingNeed a car but don’t want to buy one? Community car sharing organizations provide access to a car and your membership fee covers gas, maintenance and insurance. Many companies – such as Flexcar - offer low emission or hybrid cars too! Also, see ZipCar.
