California Wineries are Going Solar
More and more California wineries are adopting solar energy to power their operations. Given the plentiful sunshine, high power bills, and abundant roof space, going solar makes makes good business sense for California winemakers. Wineries’ busy crush season spans from August to October, using huge amounts of energy. Solar combats high electricity costs during this time.
Here are some California wineries powering their operations with solar:

Not to mention taking advantage of the tax incentives, $40,000 in tax credits on a $70,000 solar install isn’t too bad. This seems to be the economic tipping point of going green, and these vineyards are the poster children. Cheers to the elixir of life!
