For years I considered leaf blowers the soundtrack of suburban arrogance—loud, obnoxiously polluting, proof someone thought their driveway mattered more than the planet.

The first film, released in 2007, saw Homer accidentally pollute the water supply of Springfield and then attempt to save his city, which had been sealed off under a huge glass dome.

If not done carefully, bioenergy projects run the risk of emitting carbon — not sequestering it — and polluting communities already grappling with some of the state’s dirtiest air.

The polluting companies, and the government that is supposed to regulate them, are blameless.
