City of Davis Environmental Recognition Award: Business

Tuesday night we were honored to receive the 2017 Environmental Recognition Award from the City of Davis. Candidly, it was humbling and nerve-wracking. Here's a link to a video of the ceremony, and below are my rambling, bambling thoughts:

This is like the Academy Awards for us climate geeks, the anti-Scott Pruit. Thank you very much.

I am a solar simpleton. Credit for this award goes to the several hundred property owners we have helped go solar, and the little organization that is the sustainability heartbeat of our community, Cool Davis.

Ours is a community that greatly values sustainability. We value walking and riding our bikes. Driving cars that get good gas mileage, that perhaps are electric. We value making our own energy and growing our own food. We value recycling. We value conserving. And, with all those values, any time any of us do these things, it puts more money back in to our community, because we’re not paying more for gas or electricity or food.

Hence, sustainability to me is not just simply about reducing our GHGs and carbon footprint, but it’s about building a sustainable economy. But, our values have no value if we fail to make an investment in our community. We’re simply winking in the dark, kinda kidding ourselves. Because without an investment, our values are just that: They have no value.

I would like to thank the Council, the Natural Resources Commission, blah blah, mumble mumble.

Electric cars + solar panels: Does 1+1=3?

A quick note of thanks to The Enterprise for publishing the below article online today and in tomorrow's print edition. You can access the story here, and below is the prose.

A few times each week, we tender conversations with homeowners who own (or are considering purchasing) an electric vehicle and are thereby contemplating installing solar panels.

The psychology is similar: Electric cars (and solar) are good for the environment, and electric cars (and solar) are pragmatic/less expensive than the alternatives. Seems like a no-brainer – power your electric vehicle with cheap, clean energy generated by your solar panels.

But, is it?

Since 2010, nearly half of all plug-in electric vehicles sold in the United States are registered in California; the top-three models — Chevrolet’s Volt, Nissan’s Leaf and Tesla’s Model S — dominate the electric highway.

(And, many see the advent of Chevy’s all-electric Bolt in late 2016 and Tesla’s Model 3 — my deposit is in; please, Elon, late 2017? — as a tipping point for electric vehicles.)

Similarly, nearly half of all solar electric systems in the U.S. sit atop California households. (As we’ve shared, nearly one in four single-family residences in Davis now has a solar electric system, far out-pacing an estimated 5-percent penetration in PG&E territory.)

As transportation is increasingly electrified and energy generation is decentralized (from carbon-based, utility delivery to solar-generated, homeowner systems), does going solar to power your home and transport make sense? Let’s do the math.

Electricity costs
We have had the fortune of helping several hundred Yolo County homeowners evaluate solar. What we’ve learned: Their average cost of PG&E electricity is 25 cents per kWh, and their median monthly electricity bill is $185. Conversely, their cost to generate solar electricity averages 8 cents per kilowatt hour (kWh), amortized over the warrantied life of their solar panels. Solar saves money.

Transportation costs
For comparison, let’s assume an average car is driven 12,000 miles each year. If the car averages 25 miles per gallon, powered by petroleum, it will guzzle 480 gallons of gas annually. At $2.50 per gallon, annual fuel costs are $1,200, or 10 cents per mile.

Electric vehicles yield, on average, 4 miles of range per kWh. Hence, you will consume 3,000 kWh to drive 12,000 miles. If you are purchasing electricity from PG&E, your annual “fuel” cost is $750 (or, 6 cents per mile). If your electric car is powered by solar, your annual cost is $240 (2 cents per mile).

And, of course, if you charge at your workplace or one of a half-dozen free sites downtown, your cost is lower.

Environmental benefits
I can’t conceive an environmental virtue of driving a gas-powered car, though admittedly my family owns three (along with an all-electric vehicle). The environmental outcomes of electrifying your transportation with solar, though, are striking.

According to the EPA, over three years (36,000 miles) the greenhouse gas equivalents of clean transportation are:

* Retirement of 12.84 metric tons of carbon dioxide;
* Planting 320 tree seedlings, grown for 10 years; or,
* Averting 4.08 tons of waste sent to a landfill.

Many suns will set before electric vehicles become mainstream. Though cool and cheap and clean, their drawbacks are obvious: Range anxiety (Can I get from here to there?), charging anxiety (Do I need to charge it?), technology phobia (Is it too early/will it work?).

Danny Kennedy, managing director of California Clean Energy Fund, recently opined, “We’re now in a tech world, rather than a resource world. Resources are bound by scarcity — the more you use them, the more expensive they become. With tech, the more you use it, the cheaper it becomes.”

As the cost of solar and electric cars continue to descend, as the efficacy of both improve, and as PG&E rates further escalate, it will become increasingly difficult to dispute solar-fueled transportation.

The future is bright.

A (great) night at the council chambers

I have great admiration for Davis city council members. Incredibly devoted, immensely under appreciated. As individuals and a council, they can’t please everyone with every position/vote, but this group’s solid.

Admiration to the side, I usually loathe attending council meetings. Last night was different. Here’s why:

First my son was Youth Mayor for the Day (actually, for about 10 minutes, but who’s counting?). He crafted a proclamation seeking more sports fields — baseball especially — for our kids. And he learned about the sausage-making, governance process. Pretty cool for a 13-year-old, and kudos to all council members (particularly Mayor Dan) for opening their chamber.

Second, there was a simple proclamation trumpeting the upcoming (May 3) Big Day of Giving. Click here to learn more about this extraordinary, regional event. For us, we’re living a Big YEAR of Giving through our Yolo Shines program.

Third, my comrades at Sierra Energy were honored as the annual Environmental Business of the Year by the City. Grand kudos to CEO Mike Hart, a longtime friend and partner in crime. I had the pleasure of helping Mike start Sierra Energy 14 years ago and it has been a pleasure to witness the company’s emergence … potential game-changing, waste-to-energy technology. Learn more about recent developments here.

A final observation from the peanut gallery: A great quality of our community is the preponderance of smart people who care. A lot. Ours is a deeply-engaged hamlet. Conversely, a not-so-great quality of our community, if/when you want to get something done: A critical mass of intelligent citizens who care. We have a lot of people who “think it” versus “do it.” And, it hamstrings our ability to move forward.

Sierra Energy is doing it, not merely thinking about it. Bravo!
