 This whole green movement is fairly new. I wonder sometimes if we're a little too late. There was an oil crisis in the 70s, and people were waiting in line to fill up their cars. It sort of went away, and people then started buying SUVs. Hummers came out. I wonder if we're almost in a panic mode at this point, where the ice caps are melting, oil is $120 a barrel. Are we almost too late?
