The California think-tank Pacific Institute released a report—Impacts of California’s Drought: Hydroelectric Generation 2015 Update—earlier this month that contains significant false and misleading information that could negatively impact California rivers and delay the transition away from dirty energy.

First, the report and the news stories surrounding it repeatedly say that hydroelectric power is “less expensive” in California than competing sources. This statement gives credence to the anti-environmental mindset of discounting the negative impacts that dams and reservoirs have on free-flowing rivers, and disregards the externalized costs to the environment. In fact, the report omits the devastating impacts hydropower has on fish, wildlife, wetlands and countless other species that depend on healthy flowing rivers for survival. If the report would have included an “environmental full-cost accounting,” the cost of hydropower for California consumers would have been shown to be huge.
