Want to know how a government policy can effect real change? Here’s an example—I have been meaning to start switching over to LED bulbs in the house, even more so since I read a piece last summer by Marc Gunther about the newest generation of LED bulbs (“A Better Light Bulb. Again“). We’ve purchased a few LED bulbs in the last year for specific applications (in one case, some pendulum lights where we needed lots of light output but limited heat), but those bulbs have been expensive, costing up to $35 each. Then, a month ago while walking through Home Depot I saw the Cree bulbs, that were referenced in the article, selling for $9 apiece. That’s still expensive, but not so expensive that I wouldn’t consider buying a few at a time and replacing the compact fluorescent (CFL) bulbs that we currently use in the house. But, I didn’t buy any then, because I wanted to compare energy usage among the different brands of LED bulbs, as I suspected that they weren’t all equally efficient.
Fast-forward to last weekend, when I was again walking through Home Depot and saw the bulbs, but this time for $4.98 apiece, a much lower price than I expected. This turned out to be due to a promotion by Efficiency Vermont, a program funded in part by the state, that is underwriting the cost of the bulbs. At this price I bought eight bulbs instead of just a few, and took them home to try them out. I like them. They are bright, they have a warm tone, they come on instantly, they should last nearly forever, and, as my son and I accidentally dropped one and it didn’t break, they seem to be quite a bit tougher than the curlicue CFLs. But here’s the biggest bonus—the new bulbs use only 9.5 watts apiece, and we were replacing CFL’s that were rated at 13, 18, 20, and 26 watts. In the case of the first three the light output seemed the same or better, and was close even in the case of the 26-watt CFL (marketed as a 100w replacement). So, in one fell swoop we reduced our energy use for these eight bulbs by at least 50%, and possibly more, even over the CFLs, which are already many times more efficient than the old incandescents. That’s substantial.
Then, it struck me that this remarkable incentive program wouldn’t last forever, so I stopped back by Home Depot after work the other day and bought 25 more bulbs, enough to finish replacing nearly every bulb in the house. Lighting accounts for about 20% of electrical use in the average American home, and I suspect it’s an even higher proportion in our off-grid setup. In winter months we don’t currently make quite enough solar power to get by (relying occasionally on the gas-powered generator), and if the new bulbs help reduce this energy gap, then it will result in a direct savings in burning fossil fuel. A good deal.
So back to where I started, this is a good case of supply and demand principles at work. The government underwrote an incentive, and that incentive increased demand for the bulbs, and energy was saved as a result. (And judging from the near-empty racks of bulbs at the store, I wasn’t the only one who has been swayed by the low prices into purchasing more). So, a public thank-you to Efficiency Vermont, and another public thank-you to some forward-thinking legislators who set up and voted to fund the state’s efficiency programs. Demand for bulbs like these will eventually reduce their costs, and the products will stand on their own merit. The same is true for electric vehicle incentives, and a whole host of other efficiency incentives I can think of. This is money well spent, it is smart policy, and it is part of that “better path forward”. In a world where real change sometimes seems hard to achieve, here’s a program that works.
