“When you have a hammer, everything looks like a nail”
What a wonderfully simple way to describe much of our world. I am reminded of this whenever I see people working on the “energy” problem. Software people clearly know, that if only we wired everything up and monitored our energy use, the rest of the problem would be trivial. Economists clearly have the upper hand, because they can describe carbon trading as the sure fire method to reduce carbon output, increase energy efficiency, and still have economic growth. Photovoltaic manufacturers, electric car builders, and wind farm developers are among the many queuing up at the public feeding trough.
Nothing wrong with any of those solutions. Just bear in mind the aphorism.
By the way, our hammer is a whole house fan.
