That's the sound of money to wind developers who see these mountains, which enjoy some of the best wind energy on the planet, as the perfect power plant for the burgeoning metropolis of San Diego, Calif., a few hundred miles away. Already, a small 10-megawatt windfarm is going up in these hills near the town of La Rumorosa.
