Greenhouse emissions
>Obama wants Congress to set a cap on greenhouse emissions such as carbon dioxide. That would require companies to buy permits to emit greenhouse pollution.

Clean coal technology
>There is $3.4 billion in the stimulus bill for fossil-fuel research, including for technology that would allow coal-plant operators to bury carbon dioxide from the plant.

Upgrading the power grid
>There is more than $10 billion in the budget for improvements to power lines that transmit electricity. The existing network does not have enough capacity.

Nuclear waste
>Obama's budget cuts off funding for the Energy Department's plans to bury nuclear waste at Yucca Mountain. There's an estimated 63,529 tons of nuclear waste in temporary storage.

Oil and gas drilling
>Interior Secretary Ken Salazar has canceled drilling plans for public lands in Utah and Wyoming. He's also re-evaluating President Bush's offshore drilling plan.

Air pollution
>The Obama administration dropped a legal defense of Bush-era limits on mercury emitted by power plants. The Bush plan would not have required mercury cuts at every plant.

Endangered species
>Obama directed federal agencies to consult with environmental and scientific experts before undertaking construction projects that may threaten endangered species.
