Green Driving
A quarter of the worlds energy---including two thirds of the annual production of oilis used for transportation. Some savings come free of charge: you can boost fuel efficiency by 6 percent simply by keeping your cars tires properly inflated . Gasoline-electric hybrid models like the Toyota Prius improve mileage by a further 20 percent over conventional models.
A Better Fridge
More than half of all residential power goes into running household appliances, producing a fifth of the worlds carbon emissions. And thats true even though manufacturers have already hiked the efficiency of refrigerators and other white goods by as much as 70 percent since the 1980s. According to an International Energy Agency study, if consumers chose those models that would save them the most money over the life of the appliance, theyd cut global residential power consumption by 43 percent.
Flexible Payment
Who says you have to pay for all your conservation investments? Energy service contractors will pay for retrofittingin return for a share of the clients annual utility-bill savings. In Beijing, Shenwu Thermal Energy Technology Co. specializes in retrofitting Chinas steel furnaces. Shenwu puts up the initial investment to install a heat exchanger that preheats the air going into the furnace, slashing the clients fuel costs. Shenwu pockets a cut of those savings, so both Shenwu and the client profit.
