The idiom “tilting at windmills” (or turbines) derives from the novel Don Quixote by Miguel de Cervantes. It means to attack imaginary enemies, or fight unwinnable or futile battles. Big Oil and Coal (and others) are in a futile battle against clean energy. Clean energy will inevitably emerge victorious. Unfortunately, when oil billionaire brothers, Charles and David Koch of Koch Industries (apologies for putting their names on the horse and ass’s asses) fight unwinnable battles you can be certain the pointless battles will last a lot longer than they should. Putting approximately 100 million dollars of their money into right-wing coffers to keep fellow polluters happy and federal regulations lax, Koch Industries is more than eager to fight a battle that compromises our future and greatly compromises the future of our children. The same children to which they are now eagerly marketing.
