Carbon Monitoring for Action (CARMA)

Check out CARMA, this is a description from the site:

At its core, Carbon Monitoring for Action (CARMA) is a massive database containing information on the carbon emissions of over 50,000 power plants and 4,000 power companies worldwide. Power generation accounts for 40% of all carbon emissions in the United States and about one-quarter of global emissions. CARMA is the first global inventory of a major, emissions-producing sector of the economy.

The database is very searchable, sortable, and exportable. Take a look at how much CO2 your local coal power plant is belching into the air, then compare that to how much is coming from your local nuclear plant! [shameless career plug]
