As cost estimates for nuclear increase, SBSP looks better and better.
The comparison below used a WNA estimate for nuclear of $4,200/kW,
but official applications for federal loan guarantees averaged $6,500/kW,
Moody's estimated nuclear at $7500/kW last summer,
and more recently Severance estimated nuclear at $10,500/kW.
The estimate below is $15,000/kW for SBSP in 2015,
dropping to $6,000/kW for SBSP in 2024.

February 2009
Introduction
Space Based Solar Power (SBSP) is estimated to be an economically viable source of
clean and renewable energy that can utilized for mainline grid power, 24 hours a day. In
comparison to other forms of electricity production, it has advantages and disadvantages.
Space Energy will position SBSP as a valuable source of electricity, which will
complement other forms of electricity generation, in order to meet rising global demand.
Other than a strict economic evaluation, SBSP will also offer many significant
advantages to the countries that are early adopters of this technology. (More details on
