'Green' power lights state buildings

Renewable energy lights up the State House in Augusta at dusk last Wednesday. Maine is the only state that uses 100 percent renewable energy in state-owned buildings. Power generated by falls on the Androscoggin River help keep lights burning in state-owned buildings 50 miles away. The Rumford Falls hydroelectric plant in Rumford is at right.
RUMFORD - The Androscoggin River's heavy springtime flow cascades down falls at the side of a brick hydroelectric plant not far from the middle of this western Maine papermaking city.
The view from below is more than scenic. You might say it's electrifying, considering the dam's output accounts for much of the power running the lights 50 miles away in the capitol, transportation garages, prisons and other state-owned buildings across Maine.
And while the water roars through the falls, Maine quietly is assuming a nation-leading role as the only state in which 100 percent of the electricity used in state-owned buildings comes from renewable sources. Those "green," nonfossil power sources also include wind, solar and geothermal power, and power from municipal waste generators.
"Our state government purchases of renewable energy are indicative of our willingness to take direct actions to reduce global warming," said David Littell, commissioner of the state Department of Environmental Protection.
Maine is one of about a dozen states that have set goals for use of green energy in their buildings, said Sue Gouchoe of the Solar Center at North Carolina State University, whose database tracks such policies and trends across the country.
Gouchoe said no other state has a current goal of 100 percent renewable power in its buildings.
Most other states with green power purchasing requirements for state buildings set minimums of 3 percent to 20 percent, according to an energy researcher for the National Conference of State Legislatures.
Next to Maine's, Connecticut's standard is the highest, with goals of 20 percent renewable-energy purchases in 2010, rising to 50 percent in 2020 and 100 percent in 2050, said Glen Andersen of the legislative organization.
No state or other power purchaser can purchase electrons that literally have been generated by any particular source -- renewable or not. All power generation sites -- green, fossil fuel-based and otherwise -- pour their energy into a grid, through which power from a mix of sources is distributed.
With global warming a growing concern, many power purchasers stipulate that the equivalent of the power they use is generated from renewable sources. Besides financially bolstering green energy, it offsets greenhouse gas emissions.
In Maine and some other states, homeowners can opt for all-green purchases when they choose energy suppliers. A Maine law requires all competitive electricity providers to get 30 percent of their power from renewable sources.
To get its government to 100 percent, the state purchased renewable energy credits for 50,000 megawatt hours of power generated by the Rumford Falls hydro station, which is owned by Brookfield Power of Quebec.
The renewable energy credit purchase displaces about 20,000 tons of carbon dioxide emissions per year, the equivalent of taking about 2,400 cars off the road, said Chip Gavin, director of the state Bureau of General Services, which buys the electricity for state-owned facilities.
