Per Capita Davis: We’re in hot water

It’s hardly news anymore. It’s more of an annual event. Last year, 2015, was the “warmest” since someone decided to begin recording average annual surface temperature sometime in the mid 1800s. If you’re thinking this all sounds familiar, it’s because it is; the same was said of 2014. The difference this time around is that […]

Per Capita Davis: Making progress, big and small

A friend, Jim Cramer to be precise, invited me to make a presentation to the Contemporary Issues Forum he organizes at the United Methodist Church to talk about the Paris Climate Talks. I told him I’m certainly not an expert on this, nor am I really an expert on anything, but I have a deep […]

Per Capita Davis: Good news to start the year

Hello, and Happy New Year. The Paris Climate talks last month ended on a positive note, with basically the entire world agreeing that it’s time to get serious about responding to climate change. I’m determined to continue the optimism this sparked in my otherwise cynical soul into the new year, unless and until something happens […]

Per Capita Davis: We’ll always have Paris

This is the last column of the year, and I typically use it to sum up where we are in terms of progress, or the lack of it, in reducing greenhouse gas emissions. The first measuring stick is the level of carbon dioxide in the atmosphere. Data from the National Oceanic and Atmospheric Administration and, […]

Per Capita Davis: Follow the money

The Paris Climate Talks have begun and I’m awash in cross-currents of emotions; an intensification of my usual vacillation between optimism and pessimism over whether the world will get it together to save itself from adverse effects of climate change. On the one hand, I feel a bit like Charlie Brown, lining up to kick […]

Per Capita Davis: A solution is right in our own back yard

Sometimes the answers to life’s biggest questions can be right in front of us but somehow not in focus. World leaders are packing their suitcases for the trip to the Paris Climate Talks, set to begin two weeks from now (unless the recent terrorist attacks alter the schedule) and bringing with them their plans and […]

Per Capita Davis: News you might have missed

YELLOW (PAGES) JOURNALISM: Can it be true: Reading a newspaper can reduce your greenhouse gas emissions? Our family finally got rid of our land line but that didn’t stop delivery of those phone directories that periodically arrive in the driveway and are about 99.9 percent business listings and advertisements. Leafing through a recent one I found a […]

Per Capita Davis: Letters to and from the future

My last column was about the “Letters to the Future” campaign initiated by Davis resident Melinda Welsh asking regular folks and famous people to tell world leaders our concerns about the Paris Climate Talks scheduled for early December. Many scientists have identified these talks as a tipping point for policy, a last good chance to […]

Per Capita: Letters to the future

I’ve been writing this column now for nine years. I named it “Per Capita Davis” because, at its core, it’s about what we can do as individuals to help prevent or at least mitigate the biggest calamity facing the human race — global warming, the accumulation of greenhouse gases in the atmosphere to a level […]

Per Capita Davis: Change is on the horizon

The Paris climate change talks begin Nov. 30 and continue through Dec. 11. The build-up to these talks has been marked by increasing apprehension, with many scientists and others stating flatly that this may be the planet’s last good chance to avoid the worst of the predicted adverse effects of global warming. World leaders, despite […]

Per Capita Davis: What’s old is new again

When I first came to Davis in 1979, there was a lot going on in what I thought to be a sleepy little town. I arrived here to attend graduate school after undergraduate years first at UC Berkeley and then at UC Santa Cruz. Admittedly, I brought with me more than a little smugness about […]

Per Capita Davis: Little things add up

MONEY IN THE BANK: Everyone knows that increased energy efficiency is like money in the bank, but did you know that it takes a lot of energy to put money in the bank, or take it out? I’m always amazed at how thorough the state and federal governments are at finding opportunities to reduce wasted […]

Per Capita Davis: Houses, cars and batteries, oh my!

So, this is the third column in a row about storage of electricity. Recapping the first two, storage is important because as we increase the amount of electricity produced from solar and wind, the “intermittency” of electricity produced by those two technologies — due to clouds, lack of wind or whatever — means we need […]

Per Capita Davis: The battery bonanza

This is the second of three (I think) columns on the topic of energy storage; specifically, electrical energy storage. Why so much time spent on a seemingly mundane topic like energy storage? One reason is that energy storage is a necessary partner with development of photovoltaic (PV) and wind energy: These sources of energy are […]
