Cool Maps--No. 2
NPR put out a spectacularly information-dense electricity map several months ago. You can get to the image above by choosing the "Power Plants" tab and then selecting coal; the circles represent the amount of electricity produced by each plant. Due to varying technology, the amount of coal burned or the level of emissions per unit of electricity can vary widely for power plants. The "Power Plants" map is less accurate for some other sources; sometimes the web of ownership for wind farms or cogeneration facilities gets pretty tangled, but for coal and nuclear this is an amazing resource.
