What effect does it have though? (Score 1)

It is amaing if it is feasible, but what is the effect of sucking 90 quadrillion kilowatt-hours of energy out of the earth? Have there been many studies into the effects? I think the only real solution to the problem is: * Get the bulk of energy from the sun. Its free + clean. All the energy from biomass, oil etc essentially came from the sun originally anyway! * Fusion. Not really dissimilar to solar energy, since the sun is a fusion reactor. If we cant get enough from the sun, then fusion could be a back-up. Any surplus energy could be beamed out to space using microwaves to prevent heating the earth up. Energy for vehicles could use any high density energy source that can be easily derived from the suns' energy such as fatty acids. Maybe an engine could be designed that metabolises fatty acids to generate electricity rather than directly combusting them. You'd still get CO2 but it would be neutralized byt its generation at the power 'plant'.
