I can credit President Trump for our latest renewable-energy move. The day he announced that the U.S. would withdraw from the Paris climate-change agreement–in almost four years, and for fraudulent reasons–I felt a little more motivated to find more ways to cut down on our home’s carbon footprint.

We’ve long since done the easy stuff, like having insulation blown into the walls, ditching incandescent light bulbs for compact fluorescent bulbs and then LEDS, and replacing a grossly inefficient air-conditioning unit. (Okay, the A/C forced that upon us by dying in the first hot week of last summer.) Putting solar panels on our roof would make a major difference but at a high upfront cost–and waiting until next year or the year after should yield a further decline in that expense.

In our case, that leaves carbon-offset programs, in which you pay to have your energy use offset by buying a share of renewable energy produced elsewhere. Purchasing “Renewable Energy Certificates” won’t immediately leave more coal in the ground, so it’s no substitute for your electric utility selling a renewable-only option. But when your utility is Dominion Energy–which generates only 5.6 percent of its electricity from renewables (versus 33.8 percent from nuclear, 33.6 percent from gas and 26.5 percent from coal) and spends lavishly to stop Richmond from mandating anything greener–that’s all you have.

Dominion has its own REC program, but environmental advocates have criticized it for high overhead costs and its failure to support solar and wind projects in Virginia. What I didn’t realize until the president’s petulance about Paris got me to do some more research: Better options exist.

The one I picked is a D.C.-based firm called Arcadia Power that, thanks to a round of venture-capital funding last year, will offset half of your electricity for free. I was a little skeptical at first, but the energy experts at Grist took a skeptical look at the company and did not find it wanting. Arcadia also offers a 100-percent offset plan–at a higher per-kWh rate than Dominion’s REC surcharge–and a community-solar subscription option, but they aren’t things I need to figure out immediately.

Setting up an account there involved a day or two of waiting to have it take over my Dominion account–yes, I had to cough up my username and password first–and then getting confirmation that Arcadia was now managing my account. Since then, it’s been a drama-free experience. My payment was processed as usual from my bank (Arcadia apparently has to pass along Dominion’s credit-card-payment surcharge), and I didn’t get dinged for the bill a second time by Dominion.

The one part that hasn’t worked out so far: While Arcadia has a referral program, neither of the environmentally-minded friends I’ve spammed about it have signed up. So while I’m not spending more to support renewable energy, I may not actually save money on the deal.
