California First to Feel Hydro-power Crunch of Drought

Snowpack at 12 percent of average in the Sierra Nevada means there is less runoff to feed rivers and streams that run through dams to generate cleanly produced hydroelectric power. Despite the state’s ambitious clean-air goals, officials are turning to dirtier, more costly fossil-fuel plants to fill some of the power gap. They also will seek more hydroelectricity imports in a region expected to have markedly less to offer this summer.
