I'm skeptical that we'll see anything more than baby steps in the near future, but eventually this is where power is headed. The important thing for all of us to remember is this: WE NEED MORE POWER! Power will fuel- literally- our economy and allow us to continue growing and continue running more complex and proliferating technology. So this stuff is crucial.
Here's some info from one of the world's leading space based power technology ventures:
Space-based solar power (SSP) is a clean, viable solution to our world’s growing energy problems. Not limited by weather or geography, SSP solves the intermittency problems of earth-based renewables by providing a reliable and flexible energy source that is available 24/7. The underlying technology components are proven and systems will be deployable within the decade.
PowerSat Corporation is a pioneer in generating safe, clean, reliable energy from space. Solar energy is captured via satellites (known as powersats) and transmitted wirelessly to receiving stations at various points around the globe. Thousands of megawatts can be harnessed and shifted between receiving stations thousands of miles from each other—all in a matter of seconds. At a cost comparable to a large hydropower project, PowerSat seeks to leverage the gigawatts of untapped solar energy hitting the earth’s atmosphere every second, motivated by a vision of legitimate energy independence and a truly clean energy portfolio.
Just last week the company announced some new IP:

The problem with space based solar for the past 40 years has been the cost to get parts to GEO. O'Neill tried to get around that with materials from the moon. A mixed rocket-plane and and laser propulsion looks like a possible way to reduce the cost to under $100/kg. At that price, SBSP displaces fossil fuels by under pricing them. http://www.theoildrum.com/node/5485#more
