Supply and demand economics are still alive and well. As oil prices
go down, supply will eventually drop also. There's also a good chance
that demand may start coming down as various energy saving strategies
begin to take effect and alternative sources such as solar and wind
power increase. Solar is right on the cusp of becoming truly cost
effective as panels become more efficient and production costs
continue to decrease.
