The Low-Hanging Fruit of Energy Efficiency  

Posted by Big Gav in

Kevin Drum has an article on profitable (for the buyer) forms of energy efficiency investment - Climate Change's Low-Hanging Fruit.

If you don't live in California, you might not have heard of Arthur Rosenfeld. But for the past four decades, he's been the main inspiration behind a host of energy efficiency and conservation regulations that have made California the greenest state in the nation. He's retiring from the California Energy Commission this week, and today the LA Times remembers his early battles :
New homes and buildings were required to be better insulated and fitted with energy-wise lighting, heating and cooling systems. Appliances had to be designed to use less power. Utilities were forced to motivate their customers to use less electricity.

....Not surprisingly, those rules were attacked by business groups as bureaucratic job killers. Rosenfeld, who received his doctorate from the University of Chicago, was called unqualified by critics at Pacific Gas & Electric Co., one of California's largest utilities.

Yet these mandates have yielded about $30 billion annually in energy savings for California consumers. They've eliminated air pollution that's the equivalent of taking 100 million cars off the roads. They have been copied by states and countries worldwide. California's gains are so closely linked to Rosenfeld that they've been dubbed the Rosenfeld Effect in energy efficiency circles, where the 83-year-old has taken on rock star status.

Rosenfeld's ideas, far from being job killers, have been a boon for California. We have plenty of problems here in the Golden State right now, but better energy efficiency isn't one of them. In the end, Rosenfeld was right and his critics in the corporate world were wrong.

This reminds me of a current kerfuffle over energy efficiency on a national scale. McKinsey, the consultancy firm, has pressed the cause of energy efficiency for some time, and in 2007 they released a report that contained this now-famous chart (this is the 2009 version):

The point of the chart is simple: Some energy efficiency measures have a net cost and require fairly careful analysis to decide if they're worthwhile. Those things are shown on the right side of the chart. But there are lots of efficiency measures that not only reduce greenhouse gas emissions but produce net cost savings at the same time. These are the low-hanging fruit of climate change, otherwise known as "no-brainers." There are tremendous savings out there for the taking.

But there's still opposition to this idea. A couple of weeks ago Ted Gayer of the Brookings Institution wrote that McKinsey's conclusion "violates the basic principles of economics. If firms (or consumers) could reduce emissions at negative cost, then they would do so. To say otherwise is to say that they are willingly or ignorantly passing up profits." But firms and consumers do pass up opportunities to save money. Maybe it's through ignorance, maybe through laziness, maybe because of financing limitations. But there's plainly friction in the real world that doesn't always show up in simple Econ 101 models. A few days ago Brad Plumer linked to a Wall Street Journal report about an energy efficiency consultant, EnerNOC, that audited Morgan Stanley's New York headquarters and immediately saved them a bundle of money...
