11 Ford has sped up its painting process with technology that applies all three coats in one go, eliminating the need for the costly and energy-sucking drying equipment used between coats. In the process, Ford will reduce CO₂ emissions from production by 15% and volatile organic compound emissions by 10%. More important (for the bottom line), the process will save $7 per car by reducing painting time by 20%.

12 Fox has redefined eco-boom on the set of 24, switching from regular fuel to renewable-source biodiesel to feed the show's many explosions and car-chase scenes. 24 uses more than 5,000 gallons of fuel a month, and the switch hasn't increased costs.

13 In a bid to shame lead-foot drivers, next year Fiat will roll out EcoDrive, a program developed by Microsoft. The system records performance data, such as CO₂ emissions and fuel consumption, onto a USB key. Plug the key into a PC, and the program will analyze the data and provide driving tips to lower emissions.

14 Finally, something to do with skunked beer: In a partnership with Colorado engineering firm Merrick & Co., Coors produces 3 million gallons of ethanol a year by distilling waste beer. The brewery sells 200-proof ethanol to Valero Energy to be distributed at gas stations in Colorado. The program has been so successful that Coors doubled its capacity by building a $2.3 million facility in 2005.

15 This October, the Sierra Nevada Brewery in notorious party town Chico, California, installed a 250-kilowatt fuel-cell power unit and officially dropped off the grid. Drunk with power (energy efficiency is expected to be double what it was getting from Pacific Gas & Electric), the brewery plans to sell the surplus wattage back to the electric company.

16 Let there be less light! That was the conclusion of an energy audit at the Hong Kong headquarters of Star TV, News Corp.'s Asian broadcasting subsidiary, which found that by removing one out of every three fluorescent tube lights--about 1,300 in all--it would trim its CO₂ emissions by 18,000 pounds a year.
