factory in Zaragoza, Spain is set to get a roof tiled in solar panels as part of a larger initiative throughout
European operations. 183,000 square meters of photovoltaic cells will be capable of providing up to a quarter of the factory's peak demand. Zaragoza is GM's biggest European factory, and the project will cost €50m, though its benefit will be significant reduction in energy bills for the automaker. GM has 19 other plants in Europe, and the Saint Petersburg factory is next on the list for the solar treatment. Other locations may follow, though some are likely better suited than others due to a variety of environmental and business factors.
