Take, for example, Sweden's nationwide rush to convert cars from gasoline to fuels like ethanol and biogas fermented from plant waste. Stations that sell alternative fuels are springing up all over the country, and fully 13% of new autos sold in February, the most recent month for which numbers are available, can run on ultra-low-emission substances...
...country. In the northern town of Aapua, a wind farm opened just last month, thanks to local residents who began lobbying town officials five years ago; it should supply 40% of Aapua's electricity. The old university city of Lund gets 30% of its heat from a geothermal plant. And Fjaras, in the southwest, just opened a solar-powered health center. Some of these are small efforts, to be sure, but when an entire nation embraces a pledge to wean itself from oil, there's no reason it can't be done. --By Michael D. Lemonick.

...Portland, Ore., which zeroed in on global warming beginning in 1993, has already slashed emissions by 13% per capita, partly by building light rail and 730 miles of regional bikeways. In Austin, Texas, the city-owned utility was able to cancel construction of a 500-MW coal-fired power plant--planned to power 50,000 homes--thanks in part to an intensive green building program that offers energy-efficiency audits to all residents and businesses, retrofits schools and installs insulation and shade screens to reduce sunlight in low-income housing. "We're frustrated by the lack of national leadership," says...
Other cities are crafting their own solutions. St. Paul, Minn., which has had to forgo Winter Carnival ice sculptures and on-ice softball tournaments in recent years because of rising temperatures, is using a biomass-fired power plant for both heat and electricity. Keene, N.H., is harnessing methane and other gases at its landfill to run a generator that powers its recycling center. Salt Lake City, Utah, has converted 1,630 traffic stops to energy-efficient light-emitting diode signals--which alone will save more than 500 tons of CO2 pollution each year and cost the city $53,000 less...
...merger with Duke Energy, Rogers is poised to run one of America's largest utilities, and he aims to lead by example. In recent years, Cinergy has spent $1 billion to increase its use of cleaner-burning natural gas, including $200 million to convert a coal-fired plant, and Rogers has cut Cinergy's reliance on coal from 87% of its fuel to 73%. He has pledged to reduce Cinergy's CO2 emissions 5% below 2000 levels by 2012, and he is investing in projects to sequester carbon in forests. Rogers is evaluating coal- gasification technology for a plant...
