I think you guys are overreacting a bit, this isn't like fracking, there's no gas reserves they're tapping in to. It's also sure as hell not anything large scale enough to trigger a volcanic eruption.. The forces at work to trigger those sorts of events are a great many orders of magnitude larger than any amount of thermal energy extracted.

We did something similar in my home county routing grey water to some very old (extinct) volcanically active hot spots.

Welcome to The Geysers

In the Mayacamas Mountains, located north of San Francisco, naturally occurring steam field reservoirs below the earth's surface are being harnessed by Calpine to make clean, green, renewable energy for homes and businesses across Northern California.

The Geysers, comprising 45 square miles along the Sonoma and Lake County border, is the largest complex of geothermal power plants in the world. Calpine, the largest geothermal power producer in the U.S., owns and operates 15 power plants at The Geysers with a net generating capacity of about 725 megawatts of electricity - enough to power 725,000 homes, or a city the size of San Francisco.

The Geysers meets the typical power needs of Sonoma, Lake, and Mendocino counties, as well a portion of the power needs of Marin and Napa counties. In fact, The Geysers satisfies nearly 60 percent of the average electricity demand in the North Coast region from the Golden Gate Bridge to the Oregon border. The Geysers is one of the most reliable energy sources in California delivering extremely high availability and on-line performance and accounts for one-fifth of the green power produced in California.
Between geothermal activity and the large amounts of rainfall in the northwest, they're completely set for renewable energies, and it's the best kind of energy, base load!

The yellowstone caldera would also be another prime location for energy production... Were it not so far from any major populous.
