Regardless of what the federal government does or does not do in the coming months and years to incentivize and otherwise promote energy efficiency initiatives, most states are continuing to ramp up their own efforts.
California has long been a national leader in areas of renewable energy, digital innovation and fighting climate change. Occasionally, it surrenders the top spot to another state, as it has to Texas in the field of wind power. Sometimes, it gains it back.
While energy efficiency continues to play a prominent and growing role in the larger movement to transform the way society generates and consumes power, debate continues over the question of whether it really works. A recent study should help put that debate to rest.
