Your average gasoline lawn mower puts out as much pollution per hour as 11 cars. A manual push-reel mower is zero. The computer you use ... Being on all day and night, contributes 8.3 million tons of CO2 emissions. Converting your lights to fluorescents would reduce CO2 by 42.4 million tons a year. Your annual CO2 emission could be apx 54,273 pounds.... Thanks to air conditioning, heat, computers, pools, water heater, etc.
A gallon of car gas adds 20 pounds of CO2 to the air. A typical kitchen has 10 75-watt spots on all day. Replacing them with fluorescents would save $200 a year. Appliances could contribute half your electrical bill. If we drove 20 miles less each week we would reduce CO2 by 107 million tons or 9%. The US produces 1\5th of the world CO2 emissions.... Six billion tons a year.... Soon to be seven. The average house is 45% larger than 30 years ago. Buildings and transportation produce most of the CO2. Third is industry, ie refineries, paper plants that contribute 28%. But firms like Dow, DuPont and 3M have demonstrated huge savings by reducing energy. At home the top CO2 dogs are the heating pump at 5,249 pounds of CO2 per year in the US, central air at 4,067,oil furnace at 14,380, car at 11,903, pool pump at 1,496, and gas furnace at 6,967 vs TV set at 548, shaver at 1, camcorder at 3 and digital camera at 19. If you take an airplane trip in the US, you will double your daily total of emissions.
Will cutting back help? Consider that 80% of NEW energy demand in the next 10 years will come from China, India and other developing nations where economies are developing faster.
