In a much anticipated report that could affect every Floridian's pocketbook, a consultant hired by the state says solar power could be a competitive source of electricity by 2020 in many scenarios, but it will cost considerably more than new nuclear power and natural gas, the main sources of power for present customers of Florida Power & Light. Biomass -- things like plant waste, wood chips and garbage -- will be a financially viable source in all scenarios, but wind isn't likely to be much of a factor in Florida.

As Florida moves to implement those measures and consider others, businesses are concerned. ''We are injecting into the argument what the cost will be and the competitive effect of putting our state at an economic disadvantage to all other states that don't have strict emissions standards,'' said Jose Gonzalez, vice president of government affairs for Associated Industries of Florida, a lobbying group for businesses. ``It's certainly laudable. The governor is trying to do the right thing. But the way we get there is the question.''
