Competing plans

President Obama and Republican presidential nominee Mitt Romney have different visions on renewable energy.

Obama would:

• Renew $1 billion annual tax credit for the wind industry

• Incubate solar projects through aggressive use of subsidies

• Create national clean-energy standard requiring 80% of power from clean-burning sources by 2020

• Support expansion of natural gas, nuclear power to help reduce greenhouse gases

• Tighten environmental regulations on some oil production

Romney would:

• End wind tax credit

• Scale back federal subsidies for other renewables

• Roll back regulations inhibiting oil production and construction of coal plants

• Accelerate permits for projects in all energy sectors

• Open millions of acres offshore and on federal land to oil drilling
