College first to generate all electricity from renewables
Butte College in California became the first
college in the United States to go ‘grid positive,’ meaning that
it will generate more electricity from its solar arrays than
it consumes and will deliver power back to the electric grid.
Butte College, located near Sacramento and resting on a 928 acre
wildlife refuge, will see significant cost savings from its solar
arrays. The college estimates that it will save between $50 million
and $75 million over 15 years, even after accounting for project
costs and interest, by eliminating its electricity bill, getting
paid for excess electricity production, and avoiding future electricity
Butte College now operates a total of 25,000 solar panels that
will generate over 6.5 million kilowatt hours of electricity
per year – enough to power over 941 average-sized homes, or the
equivalent of removing 615 passenger cars from the roadways.
