    Why can't the people who run coal mines start shifting to renewable energy, or maybe build some factories that produce more efficient wind energy devices?  For heaven's sake, just do it!

    There are lots of things we might not want to do, but when we have to, we do it.  We need someone to produce less expensive solar panels so that millions of people who need a new roof will put solar up there and do it quickly.  I would do it if the cost went down, or if I could get a tax break.

    What's happened to us?  Do we want to live in the past forever?

      for cleaner than we've got retrofits, as opposed to totally clean new stuff.  The syllogism seems pretty obvious to me:

      We reduce CO2 starting about now, or else.

      We can't build anything fast enough to do the above, because of our farting around.

      Therefore, we should try some stopgaps on what we have.

      A coal-burning power plant with Carbon Capture and Sequestration (CCS) (incorrectly called "Clean Coal") will only produce about 3/4 of the electricity that a coal-burning power plant without CCS will produce, because of the energy needed to do the capturing and storing.  So the company running the plant will have to charge more for the power in order to cover their expenses and make a profit.  In other words, it will be too expensive.  Renewable energy, about half wind and most of the rest PV and solar thermal, would be cheaper than "Clean Coal".  And that's WITHOUT accounting for the disposal of coal ash as the toxic waste that it is!

      I would do it if the cost went down, or if I could get a tax break.

      Start saving money now!  Within five or six years, PV power will be about the same cost as retail electricity from the power company.  After that, PV will be cheaper.  And between now and then a tax break might be authorized.  Plan ahead, aim at four or five years from now.  In the meantime, work on reducing your electrical usage.  

      Renewable energy brings national security.
