The WWF PowerSwitch! Challenge is for power companies to support binding limits on national CO2 emissions. They must also provide 20 percent energy from renewable sources, increase efficiency by 15 percent or retire the least efficient 50 percent of coal generation by 2020. Renewable sources may include solar, wind, sustainably harvested biomass, low-impact small-scale hydropower, geothermal and methane recovery from landfills or farms.
Efforts may include improving energy efficiency in power production, upgrading distribution technologies, transmission optimization efforts or reducing overall demand from customers in a service territory as part of a strategy to diminish the need for new electricity generation capacity.
