EPA Wants Real-World Environmental Data From the Smart Grid

By Jeff St. John on Greentech Media.com, November 6 2009

The Environmental Protection Agency is eager to see some utility data on the positive environmental impacts of smart grid deployments around the country. Just what it wants to do with the data is still up in the air.

Estimates of the smart grid's impact on reduced greenhouse gas emissions, pollution from fossil fuel-fired power plants, and overall energy efficiency gains are all over the place.

A big one, EPRI's Green Grid study from last year, put the potential energy savings at 56 to 203 billion kilowatt-hours across the country. That could equal a carbon emission cut of 60 to 211 million metric tons, depending on factors such as how dirty the energy of a particular utility was to begin with, before it started using less of it through smart grid systems.
