Solar footprint

A complete cost-benefit analysis of photovoltaic solar cells, published in the International Journal of Environmental Technology and Management by researchers in Italy, suggests that their cost far outweighs the financial savings one might expect from reduced electricity costs. On the other hand, the cradle to grave analysis carried out by Giacomo Bizzarri of the University of Ferrara and Gianluca Morini of the University of Bologna, suggests that over the whole lifetime of PV panels from manufacture to disposal the carbon footprint and energy costs are lower than the amount renewable energy produced. The balance will tip in favor of solar cells should the cost of electricity generated using fossil fuels rise three or four times today's price.
