Nuclear
If we need a technology that provides electricity without greenhouse gas emissions, we already have one: Nuclear.
Source: NREL, Warren GtetzA nuclear power plant in California. One of about 106 reactors in the country (U.S.) producing 20% of the electricty! The reactor building is framed by the large cooloing towers that emit water vapor and steam into the environment (no nuclear radiation from the cooling towers).Recall the discussion on the nuclear future for the US? We have an aging nuclear reactor "fleet"; and so the predictions are that the % of power generated from nuclear is going to decrease (for 2 reasons: as the economy and energy production grows the output of nuclear will remain about the same but the % contribution will be less AND decommissioning of nuclear plants will result in a loss of capacity). The likely contender for filling the gaps in our energy supply: natural gas and coal! See the Bush administrations thoughts and a pro-nuclear stance. Perhaps fear of climate change will overcome the fear of nuclear power? We have no plans to build new reactors currently so if this is going to play a role in CO2 emission growth reduction NOW is the time to act!
