Looks like a good area for solar panels to me too. Other methods of renewable energy that could be used at the stadium and thus save the Albion money are:
Air Source Heat Pumps
Ground Source Heat Pumps
Wind Turbine
Plus there is micro-generation technology too:
Micro CHP
Considering the stadium was only built just over two years ago I cannot understand why there was never any renewable energy included within the plans for the stadium.
