If the US government wanted to reduce CO2, they would have used some of that $787 billion stimulus plan to fund nuclear reactor construction (or guarantee nuke loans) so that we reduced the amount of coal we burned for electricity. Could't they have kicked $125 billion to build 10 plants to kickstart the switch. Direct CO2 reduction!
To Quote along with back of the envelope math at the link:
One third of the CO2 emitted in the US from human activity comes from burning
coal to make electricity.
