In August, news covered the plans of the Lewiston-Auburn Water Pollution Control Authority to build a anaerobic digester plant at its sewage treatment facility. The plant would reduce the Authority's solids disposal costs and could generate significant energy from the methane produced. Now, the Lewiston Sun Journal says they're clarifying that it is "not a given" that the Authority will develop the project.
Hydroelectricity: a rock has fallen onto the Ennis Dam on the Madison River in Montana. Here is a map of the Ennis Lake and gorge area. You can see pictures here and a map here. It looks like Ennis Lake will be drawn down 5' to relieve some of the back-pressure on the dam, and then later draw it down another 4' for a full inspection and possible repairs. Ennis Lake only averages 8'-9' deep, so this drawdown will have noticeable effects -- if not as permanent as the effects of drawdown prior to breach. Hopefully the drawdown will not cause landslides and erosion as at Fort Halifax on the Kennebec River in Maine.
