Plasma TV's are of the most wished for holiday gifts. But they're expensive in
more ways than one. They cost $2-thousand dollars or more apiece. And they use
up to five times as much electricity as regular TV's. MIT Technology Review
magazine says plasma TV's are such energy hogs that the global adoption of
them could increase electrical demand noticeably. That would increase the
chances of blackouts and the volume of greenhouse gases emitted by power
plants.
