This week, the Supreme Court made the unfortunate decision to temporarily block President Barack Obama's clean-energy plan. Many of the arguments made against it have also been made against California's clean energy policies.
The state's new landmark clean-energy law took effect this month, ensuring that at least 50 percent of the electricity powering our state comes from renewable sources such as solar, wind and geothermal by 2030. This policy strengthens California�s position as a global leader on clean energy and flips the script to make renewable energy �mainstream� and fossil fuels the �alternative.�
Since California first established clean-energy requirements 15 years ago, critics have argued that, in addition to being unachievable, aggressive renewable energy goals would destabilize the power grid, eliminate jobs and hurt ratepayers.
Today, California produces more renewable energy than any other state in the nation and the major utilities are on track to meet and exceed their targets in the coming years. We are now in a good position to evaluate these claims.
