Well, it's dark as a dungeon, way down in . . . oh, never mind. Now, this is irony:
When a famous coal museum wanted to save some money on its electricity bill, it turned to the obvious power source. Yes, Wales' Big Pit National Coal Mining Museum has installed 200 solar panels on its roof.
The panels are expected to save the museum some $650,000 over the next 25 years, the trade magazine Renewable Energy World reported Monday. Not a bad deal for an up-front cost of about $115,000.
