You know it's something we need to do, and it will create economic activity, it could also position us to be competitive in a new industry with global marketing potential, but the problem is that at this point it is still a net minus economically. Nothing will give us the energy bang for the buck that oil has. It's not like the IT thing where you not only saw economic acitivity around it's adoption but you also saw productivity increases, alternative energy at this point still has a negative impact on the productivity of capital.
