Solar panels

I was just wondering if the new stadiums that are being built for the New York Yankeesand the Mets are going to have any type of alternative energy products installed. Maybe they can install solar panels on the roof to light up the stadiums. I know installing such products on your home are a bit expensive, but when you have deep pockets like George Steinbrenner and Fred Wilpon they should set an example and lead the way to a cleaner and brighter future. Heres a stretch, maybe M.L.B can use bats that are made from something other than wood.
