Energy efficiency is the Swiss Army Knife of public policy. It’s Veg-o-matic. It slices and dices. No matter the question, energy efficiency just might be the answer.
What technology saves you money on your utility bill? How can businesses become more competitive? What reduces greenhouse gas emissions at the lowest cost? Energy efficiency is the correct answer to all-of-the-above.
Now add another benefit: energy efficiency can help prepare us for climate change.
Think about the hot summer days when electricity use skyrockets. On L.A.’s hottest day on record – 113° Fahrenheit on September 27, 2010 – LADWP delivered a whopping 6,177 megawatts. It was the all-time high in power demand, mainly to power air-conditioners and refrigerators.
But, when the grid is overtaxed, there’s also a high likelihood of power outages. More than an inconvenience, blackouts are a public health problem. During the Chicago heat wave of 1995,

Despite the conventional wisdom that Southern California only has one season, some wag suggested it does indeed have four: Fires, floods, earthquakes and riots. So far this year we’ve had none of those, for which I am grateful, and I hope our luck holds.
I say luck because Los Angeles County leads the state in fire risk. Of the million homes in California in high-risk fire areas, half are in our county. Seven of the 10 most expensive fires in the U.S. since 1990 have been in California, and insurers paid some $5 billion in wildfire claims in 2003, 2007 and 2008.
Meanwhile, wildfires across the country have set new records. Nine million acres of forest were destroyed this year in 45,000 wildfires. An area larger than Massachusetts was burned over in five western states, including ours. That’s 13,000 square miles blackened, wild life killed, trees and brush scorched and burned.
After a presentation by Climate Resolve on the local impacts of climate change last month, our host, Jonathan Parfrey, jokingly told us that anti-depressants would be passed out at the door. Gallows humor is understandable and – for me – always necessary when faced with hard truths. But dare I say that I also felt slightly more hopeful armed with information that would help us plan for the future?
This briefing, held at the Municipal Water Department, presented the first in a series of studies, sponsored by the City of L.A. and the U.S. Department of Energy, that focused on how climate change will impact L.A. County by mid-century. A lot of complex modeling went into the study, and – in this era of climate science denial – our presenter, Dr. Alex Hall, the study’s lead author, was at pains to explain it to us.
