According to the Giants team website, the Giants intend to install 590 solar panels in at&t park to make the stadium more energy efficient. Here’s some info taken from the Giants’ website,

“We will showcase solar power in one of the most visible locations on the waterfront. In turn, we hope to send a message to our fans, television viewers and the greater community about the importance of using energy wisely and efficiently.

The 590 solar panels are about the same as 40 home roof systems and will be built above the gates on the back of the stadium near McCovey Cove. Other panels will be placed on the roof near the front of the stadium by the Acme Chophouse restaurant. The installation will start in April and be finished in about two months.”

I cant say that I am surprised by this news, after all, it is California. I wonder if we will see anything similar in the nationals stadium once it is finished.
