Solar

Musk and Me

I signed up for a free quote on line.

With all the talk of the “existential threat” to traditional utilities from solar and other disruptive technologies (and the blowback against net metering in various states), I thought I’d check out SolarCity first hand.

Community Solar

Answers to questions you were afraid to ask

Community solar is expected to jump fivefold. What exactly is it and how exactly does it work?

Solar at High Noon

Surplus generation at mid-day calls for long-duration energy storage.

Utility execs and PUCs should plan now to handle extensive solar penetration, including the significant overgeneration that can occur at mid-day.

Solar Shines As Regulatory Battles Abound

A tough legal and financial terrain is confronting producers, utilities and regulators.

State commissions are challenged to find the sweet spot whereby utilities can afford to maintain their systems and homeowners are motivated to go green.

There and Back Again

Why a residential demand rate developed 40 years ago is increasingly relevant today.

Why not design a rate that allocates the higher system cost to customers based on their actual energy demand?

Before the Death Spiral, a Black Hole

How rooftop solar picks off the utility’s largest and most lucrative customers.

Let's make it clear also that affixing solar panels to your roof won't take you off-grid. Indeed it takes you to even greater dependence.

Time for 'Megawatts Without Borders'

Why can’t we fly in a portable power supply to aid a poor country in distress? Here may lie opportunity.

Zambia, the landlocked and poor country in Southern Africa, is suffering a crippling power shortage. Musing about this, I find it extraordinary that there are no reliable, affordable, and portable power supply units that could be brought in to help Zambia.

Rooftop Solar 2.0

Hawaii and California grapple over net energy metering.

While the underlying questions in each state regarding net energy metering are much the same, the two PUC's will approach the issue from different perspectives.
