In energy technology as elsewhere, Trump is hobbling American science with budget cuts and demands for political submission. The epitome of his approach is the decision to give political appointees rather than experts the ultimate decision on each project, replacing scientific merit with politics as the deciding factor. His war on science is also a war on future economic growth. And his effort to halt creative destruction is the pathway to a stagnant economy. By trying to prop up an incumbent industry threatened by new technologies, he's undercutting a central driver of economic growth.
