How to encourage frugality: make it a contest

sad face and happy faceThe New York Times reports on an intriguing – and apparently effective – method of encouraging consumers to curb their energy habits. A Sacramento utility company printed comparisons of energy use on their bills, and rated the consumers by comparison to their neighbourhood’s averages and best figures, labelling their success or failure with a happy or sad face respectively.

When the Sacramento utility conducted its first assessment of the program after six months, it found that customers who received the personalized report reduced energy use by 2 percent more than those who got standard statements…

Some clients complained and the utility stopped deploying the frowning faces, but the idea has apparently been taken up by other companies elsewhere. It’s interesting to note that this method is apparently more effective in encouraging efficient energy habits than emphasising the financial benefits or environmental impacts.

But of course, it’s playing on the urge to conformity, and there will always be those who react against such angles of attack. And while the end in this case is benign, it’s a strong reminder that anyone with a psychology (or marketing) degree has a lot more power to manipulate you than you might suspect.

What the hell is a ‘smart grid’, anyway?

electricity pylonOne of President Obama’s first actions has been to announce his intentions to build a ‘smart grid’ for the US energy infrastructure. WorldChanging explains the concepts behind the buzzphrase, and I’ll paraphrase their five broad categories here:

  • End-user smart metering to use energy more efficiently
  • Systems to integrate electricity generation with electricity storage
  • A communications network that shares data on performance, demand and availability of power
  • An ‘application platform’ that allows third-party utilities to connect the above systems together in useful ways
  • Monitoring and controlling systems that allow the grid to respond to service interruptions in a self-healing manner

In other words, it’s a lot like an internet for power, if you will – not to mention a far cry from the crude lacework of cables and substations we have at the present time. There’s a lot of work to be done, but the benefits of investing the time and money promise to be immense. I wonder what our lot in Whitehall are doing about the UK grid at the moment?

If you’re interested in seeing the sixty odd discreet technologies that break down into the five groups above, the US Department of Energy has made a big old PDF report on smart grids.

Hybrid fusion-fission energy generation a possibility

danceWe haven’t had too much luck creating energy-producing fusion reactors, but according to researchers at the University of Texas there is a possibility of creating hybrid between a traditional nuclear fission and a fusion reactor, a sort of fusion of the two ideas, to ameliorate the problems of fission:

“Most people cite nuclear waste as the main reason they oppose nuclear fission as a source of power,” says Swadesh Mahajan, senior research scientist.

The scientists propose destroying the waste using a fusion-fission hybrid reactor, the centerpiece of which is a high power Compact Fusion Neutron Source (CFNS) made possible by a crucial invention.

One hybrid would be needed to destroy the waste produced by 10 to 15 LWRs.

99% of the really dangerous transuranic waste from the first part of the cycle is consumed in the following part, so that overall the output is less harmful and remains so for less time.

Peak coal in Christmas stocking?

A new report from the American Geophysical Union suggests governments may be substantially over-reporting coal reserves, from Ars Technica:

Such fallacious reporting is nothing new—the United States government happily overestimated oil reserves in the 1950s and 1960s until peak oil hit the lower 48. David Rutledge, professor of engineering and applied sciences at the California Institute of Technology, claims the same mistakes are being repeated with coal.

His results, reported in a panel discussion at this year’s American Geophysical Union meeting, state the world only has 662 billion tons of coal, including reserves already exploited. The estimate is well short of the 1,027 billion tons remaining in proven and projected reserves, according to the World Energy Council.

Leading to the possibility of imminent peak coal.

Spain’s solar graveyard

When they perfect that spinach-based solar power, maybe they’ll use it to landscape cemetaries:

Santa Coloma de Gramenet, a gritty, working-class town outside Barcelona, has placed a sea of solar panels atop mausoleums at its cemetery, transforming a place of perpetual rest into one buzzing with renewable energy.

The town doesn’t have a lot of room for solar, so the cemetary was the only place for 462 panels that can light up 60 homes. The panels are arranged above mausoleum niches, and the town’s residents seem to appreciate the respect for the dead shown by the placement.
