The extent to which a renewable energy technology has proved its usefulness is the exact extent to which environmentalists now oppose it

…environmentalists have revealed that their real attitude toward renewable energy is no less hostile than their attitude toward all other forms of man-made power. After the installation of hundreds of "alternative" energy plants in the state [of California] — in the nation's most ambitious program to build environmentally correct power plants — the greens have begun to reject one renewable power technology after another.

After global warming, the environmentalists are starting to come out against the wind industry! Read Jack Wakeland's take on the whole renewable energy movement.

The extent to which a renewable energy technology has proved its usefulness is the exact extent to which environmentalists now oppose it. The extent to which a technology has proved unproductive is the exact extent to which environmentalists continue to embrace it.

…Environmentalists ultimately object to the amount of power produced, regardless of how it is produced. The instant that any technology promises to supply power on an industrial scale, it becomes an unpardonable evil that must be stamped out by force-either by government policy or by direct action.
