I don't think "space" is a short term solution in the slightest. It's more an eventual, partial solution. Wouldn't the general idea be to put things like solar cells into space, to increase the amount of harvestable energy we can use, not humans? Very long-term projects like space elevators, mass drivers etc. can help reduce the amount of energy (from Earth) that is required to efficiently launch something.
