Getting a dose of electricity power losses

I now have the opportunity to answer my own question of a few blogs back; we lost power for 14 hours in our rental in Vermont. Energy is such an essential aspect of modern life, and electricity and its deliverance is a fragile commodity. We don't appreciate it until we lose it.

We were on our way to dinner in Waitsfield when suddenly my headlights illuminated power lines all over the road ahead of us. The lines were snaking in the high winds, which had knocked down a utility pole.

You see, it had been almost 60 degrees fahrenheit that day, and the rapid and unprecedented melting for Vermont (global weirding :) had apparently made the base of the pole unstable, so the wind easily knocked it down.

With the electricity off, we three-point turned away from the wires and drove route 17 west to Bristol for dinner. Then the fun started (for me at least). We returned to our little rented house, then by candlelight made a big "lodge fire" in the stone fireplace. The others took the two flashlights and went to sleep in the loft, while I slept by the fire and kept it going all night. It was wonderful.

I woke up when the sun came up and made camp coffee by heating the water in the fireplace. It was toasty and cozy in the room, and I didn't miss power for a second (although I am typing on a laptop right now). No vapid TV and blaring boom boxes; the cacophony of power excess. I was vaguely disappointed when the power came back on, although my family appreciated it, since my son had kind of a bad cold.

Everyone has to prepare themselves for a possible bad energy crisis, and more so, for gasoline supply shortages, which could happen within the year. What would you do if you suddenly couldn't get gasoline for several days or weeks? Have you even thought about it?

Another thought that came to mind was that a hybrid makes a pretty good energy-storage device.

When I turned on the Prius that night, it was the only robust power source on in that dark settlement, save for the amazing starlight. There are lots of proposals out to use millions of plug-in hybrids for energy storage during peak electricity demand, as well as to charge them up during off-peak hours.

Hey wait, the earth is cooling...

I have heard a few arguments for global cooling of late.

This is a huge issue because, for example, President Obama may propose a far-reaching cap-and-trade system for CO2. While any opposing theory deserves consideration, "global cooling" discussions should not become another excuse for inertia unless the evidence is extremely strong and a scientific consensus forms around it, because the stakes are too high for future generations.

First, all short-term anecdotal evidence, such as glaciation in Alaska, should be thrown out, because one or two years is just a nanosecond in geological time.

You can just as easily find anecdotal evidence for continued warming in other regions.
Tell the Australians that their continent is "cooling off," or the people in southern California or Arizona, whose forested regions are often on fire. There are a lot of villages in Alaska where the permafrost is melting, causing their abandonment.
I've visited a glacier in Switzerland for the last 15 years (it has lost 30 percent of its mass since the 1970s), and it added snow last year, but that doesn't mean that "phew, global warming must be over."

"Global weirding" I've heard is a much better term for what's happening.

In addition, weather patterns are heavily affected by the growth of algae in the seas (algae is an important CO2 sink, and is critical for the formation of reflective clouds because it generates the cloud-seeding precursor chemical dimethyl sulfide).
The upper layer of the oceans has warmed over the decades, creating vast "deserts" where algae plumes used to flourish. Some scientists have concluded that runaway global heating can occur partly because of this massive algae destruction. See James Lovelock's "The Revenge Of Gaia."
