Wisconsin should drastically reduce greenhouse gases by mid-century, consider offshore wind farms, set up new auto emission standards and use more biofuels, a task force formed to fight global warming recommended in its final report Thursday.

Gov. Jim Doyle created the 29-member panel by executive order in April 2007 and asked it to come with ways to reduce greenhouse gas emissions.

Among the task force's recommendations:

• Cut greenhouse gas emissions to 2005 levels within the next six years, and reduce that by another 75 percent by 2050.
• Create a single agency to track greenhouse gas data and efforts to control emissions.
• Study the potential for offshore wind in the Great Lakes and establish statewide wind farm site standards.
• Consider nuclear power.
• Set up greenhouse gas emission standards for cars, light trucks and sport utility vehicles while promoting hybrid cars.
• Increase the availability and use of renewable biomass and biofuels.

The report now goes to Doyle for his consideration.
