Insight and inspiration in turbulent times.
Va. Governor Bob. McDonnell is on a GOP VP short list and recently threw his endorsement to candidate Mitt “corporations are people, my friend” Romney. But in an era of energy decline it’s worth learning how heavily Big Coal funds McDonnell, who calls himself a “friend of coal,” and how uncommitted he is to clean energy.
High oil prices ensured that profits at the major oil companies rose again in 2011 – Shell’s full year profits leapt 54% to $28.6 billion while Exxon’s increased 35% to $41.1 billion. With this kind of money at stake it is no surprise it is almost impossible to get a sensible debate about our energy future…
Where will computing go in the coming years? I thought I should find out, so I watched a roundtable and other talks and interviews on the subject (warning: it’s pretty dry stuff). I came away underwhelmed. I struggled to figure out what these guys were seeing that I wasn’t. I’m not sure I’ve figured it out. Eventually I came back to the one key issue that’s missing from their roundtable conversation—and that of most conversations among engineers in the computing world—limits, both ecological and material.
Cesare Marchetti proposed hydrogen (H2) as a large-scale energy vector almost fifty years ago. The main concern then was to find a simple way to feed transport systems with what seemed to be a fountain of energy about to come from the expanding nuclear park. The nuclear dream is largely gone, but hydrogen lives on. Is this dream about to come true as a piece in the transition puzzle to a post-fossil fuel world? That’s what I was expecting to find out at a renewable energy / efficiency conference the University of Lorrain.

Last March, a 9.0 magnitude earthquake and subsequent tsunami left nearly 20,000 dead or missing and destroyed 125,000 buildings in the Tohoku region of Japan. The two disasters also caused three reactors at the Fukushima Daiichi nuclear power plant to melt down, which released dangerous levels of radiation into surrounding areas and led to national power shortages. Tokyo’s iconic neon signs were switched off as rolling blackouts spread across the country. Faced with the greatest reconstruction task since World War II, Japan is asking difficult questions about the future of its energy supply and just what sort of society should emerge from the ruins.

With the exception of tidal energy, our focus thus far has been on land-based energy sources. Meanwhile, the ocean absorbs a prodigious fraction of the Sun’s incident energy, creating thermal gradients, currents, and waves whipped up by winds. Let’s put some scales on the energetics of these sources and see if we may turn to them for help. We’ve got our three boxes ready: abundant, potent, and niche (puny). Time to do some sorting!

When your local utility buys more renewable energy to power your lights and computers, what more do you get besides the power?
You get cleaner air, fewer respiratory health problems, and lower health-care costs.
You get local jobs building and maintaining green power plants and a better foothold in the fast-growing, multi-billion dollar global renewable energy industry.
If you use the power to charge the new plug-in electric vehicles now available, you reduce our imports of foreign oil and increase our energy security.
And finally, you reduce the greenhouse gases that are leading to the severe, threatening weather events spurred by global climate change.
It’s late December and an icy fog cloaks the northeastern state of Uttar Pradesh. Here, far from the cities, smoke rises in dense, choking spirals from meagre wood fires and scantily-clad children shiver against the cold. These are largely farming families, and their mud huts fortified by the occasional brick wall are for the most part devoid of light, heat or clean water. But it is here in Uttar Pradesh, one of India’s largest and poorest states, far away from the country’s straining power grid, that US-born entrepreneurs Nikhil Jaisinghani and Brian Shaad have started to pioneer a wholly different energy system, designed to meet some of the most basic needs of the poorest.
Who hasn’t enjoyed heat from the sun? Doing so represents a direct energetic transfer—via radiation—from the sun’s hot surface to your skin…We have already seen that solar PV qualifies as a super-abundant resource, requiring panels covering only about 0.5% of land to meet our entire energy demand (still huge, granted). So direct thermal energy from the sun, gathered more efficiently than what PV can do, is automatically in the abundant club. Let’s evaluate some of the practical issues surrounding solar thermal: either for home heating or for the production of electricity.
