California Rooftop Solar Mandate: An example of bad groupthink?
Here are the key reasons.
Rooftop solar is about as effective in reducing emissions as waving a broom into the smog. UC Berkeley’s Severin Borenstein argued this in his note to CEC Commissioner (http://faculty.haas.berkeley.edu/borenste/cecweisenmiller180509.pdf). Note: Borenstein also alleges that CEC has failed to involve experts in energy economics in its decision making process – something that is not a good policy formation practice.
UC Davis economics professor James Bushnell accused CEC of “regulatory groupthink.” (https://energyathaas.wordpress.com/2018/10/22/how-should-we-use-our-roofs/) and offered an alternative to roof solar that can generate far greater environmental benefits. There are, of course, other, more efficient ways for deriding emissions, including: mandating more urban density, raising home and cars efficiency standards, expanding the renewable energy mandate, improving grid efficiencies and transmission expansion, and so on. Once again, CEC did not allow for any independent assessment of the proposed plans economic and environmental impacts.
