California’s Fires Prove the American Dream Is Flammable.

This fall, California residents awakened to a new reality of inconvenience and terror. In early October, the utility companies Pacific Gas and Electric, San Diego Gas and Electric, and Southern California Edison all announced precautionary power shutoffs for thousands of customers, prompted by especially hot, dry conditions and forecasts for strong winds.

Just days after the first announcement, a fire broke out in Los Angeles. The Saddleridge Fire burned through almost 9,000 acres in the northern San Fernando Valley, around the hillside neighborhoods of Sylmar, Granada Hills, and Porter Ranch. One person died; 88 structures were damaged, and 19 were destroyed. Although the cause of the fire has not been determined, initial reports pointed to SoCal Edison transmission lines. Then, in spite of the shutoffs in other parts of the state, the massive Kincade Fire broke out in Sonoma County two weeks later, consuming nearly 78,000 acres and destroying 374 structures. A PG&E transmission tower was noted as a possible cause. 
Fires have dominated the California news cycle in the past, as the dry season dragged into October and the Santa Ana winds started to blow. But this fall seemed different. In the wake of November 2018’s Camp Fire—the deadliest, most destructive fire in the state’s history, killing at least 85 people—we entered what might be considered a year of climate change awareness, bookended by the news that we may only have a dozen years to contain global warming and the Global Climate Strike this September. News accounts about wildfires have taken on even greater urgency. As many commentators have noted, the changing climate and ongoing deficiencies in the regulation and management of utility companies present a new, dreadful normal.

The ‘utopian’ currency Bitcoin is a potentially catastrophic energy guzzler

The recent upsurge in the price of Bitcoin seems to have finally awakened the world to the massively destructive environmental consequences of this bubble.


These consequences were pointed out as long ago as 2013 by Australian sustainability analyst and entrepreneur Guy Lane, executive director of the Long Future Foundation. In recent months, the Bitcoin bubble has got massively bigger and the associated waste of energy is now much more widely recognised.

In essence, the creation of a new Bitcoin requires the performance of a complex calculation that has no value except to show that it has been done. The crucial feature, as is common in cryptography, is that the calculation in question is very hard to perform but easy to verify once it’s done.
