California homeowners have an odd electricity supply problem and it has nothing to do with the US State’s focus on renewable energy.

PGE, the power company which serves San Francisco, has been turning off the electricity supply to homes in windy periods in the area to prevent forest fires, after a major fire last year caused by their power lines caused billions in damage and killed scores of people.

The company was meant to prevent this by clearing the brush around their 27,000 miles of power lines, but so far managed only 7000.

Bill Johnson, the CEO of Pacific Gas & Electric, recently admitted that it could take 10 years before such outages were no longer very common, leaving homeowners in a bind.

Tesla CEO Elon Musk as been only too happy to ride to their rescue, proposing Tesla Solar and Tesla Powerwall as a solution.

Of course, a Tesla Solar/Powerwall combo is pretty expensive, with a medium system with two Powerwall batteries costing $24,900 even with incentives.

On the other hand, the average house price in San Francisco is $1.3 million, making a $24,900 system less than 2% of that price, and Musk notes its presence is likely to increase the resale value of a home, compared to a neighbouring home which remains prone to random blackouts.
