http://pressherald.mainetoday.com/story.php?id=158277&a... Some people around Portland know Alfred "Fred" Padula for the pointed e-mails he fires at them from a computer in his energy- efficient home near Back Cove.
Padula is a prolific critic, a nag even, of local institutions and bureaucracies that he believes are not doing enough to fight global warming. And not many escape that list.
But other people know a different, more private, man. That's the Padula who volunteers to help people make their homes more energy-efficient and donates untold thousands of dollars for things like solar panels on school buildings, climate education programs, and library collections on global warming and energy conservation.
Padula, a retired history professor, is not a politician or a celebrity. You've probably never heard of him.
