Not bad...

I'm not sure it's on a level playing field. Do big oil companies make
solar thermal plants?

  The largest and most efficient solar electric technology people have
  so far managed to develop is called the "parabolic trough solar power
  plant." Such plants consist of long rows of mirrors curved in the shape
  of parabolas, which bounce and focus sunlight onto insulated pipes,
  heating a fluid to make steam and drive a turbine... Nine plants were
  built in California's Mojave desert in the late 1980s and early 1990s.

  Those plants produced more electricity through the end of the last century
  than all other solar electric tecnnologies in the entire world combined!
  This includes all direct solar to electricity conversion technologies
  including power towers, dish sterling systems, and photovoltaics, but
  does not include wind or hydroelectric technology.

There aren't any, I don't think.  The electricity is too expensive.
Conceptually, they aren't hard to build, it's just the cost of
materials, etc.  If it were cheap enough it would be here, and no one
could stop it.

The power plants are still there.
