A123 introduces new battery
From the Energy Blog:
A123 Systems today introduced its 32-series NanophosphateTM Lithium Ion cells, specifically designed for Hybrid Electric Vehicle (HEV) and Plug-in Hybrid Electric Vehicle (PHEV) use.
The 32-series cells are designed with abuse-tolerance in mind. A123 Systems Automotive Class cells take advantage of lessons learned from the mass-production of ANR26650M1 cells, used in DeWalt's and Black & Decker's power tool lines, in order to deliver 10+ year and 150,000 mile projected life requirements in engineered automotive battery packs. The cells have shown minimal power degradation and impedance growth after 300,000 cycles. The battery is able to operate at a temperature range of -20 F to 140 F (-29 C to 60 C).Personally, if I owned a plug-in hybrid that could go thirty miles on a charge, I would fill my tank about twice a year.

Patrick Moore proves to be — gasp — a nuclear shill
We anti-nuclear folks are frequently accused of closed-mindedness. Like, you know, Chernobyl is so 1980s. Get with the here and now, man.
So I was interested to see how nuclear shill extraordinaire Patrick Moore would react to the news that the Canadian oil industry is increasingly interested in geothermal power as an alternative to nuclear in the heat-starved tar sands developments. The heat produced by obviously-feasible technology would be a perfect fit, and if those tree-hugging hippies in the oil sector are interested, surely there's something to suggest it, right?
Nope, not for Moore. It's nuclear or nothing. Talk about closed-minded.

New financial instruments may one day plug cities’ building codes into global carbon market
The William J. Clinton foundation has arranged billions in financing to help a coalition of sixteen cities cut urban emissions by applying a range of energy efficiency measures to aging buildings.
Efficiency measures tends to get lumped in under the heading of conservation, but they really deserve to be their own full-fledged category of solutions to global warming. If conservation is simply doing less of a polluting activity, efficiency is doing the same activity with less energy. Turning off the lights is conservation. Screwing in a compact fluorescent light bulb is efficiency.
Efficiency measures deserve their own category because they are among the most important strategies for reducing emissions. Emissions reductions from efficiency projects are immediate (which is good), they are often cheap or even free (which is great), and they don't require individuals to make significant changes to behavior (which is important to quick adoption, no matter how much we might wish otherwise).

Now There’s Room for a Live Earth Concert
Scientists find snowmelt, new species in Antarctica It’s been a bad news-good news kind of week for Antarctica. Scientists from NASA and the University of Colorado revealed that a California-sized expanse of snow melted there during a warm spell in 2005, farther inland and at higher elevations than expected. The team was cautious about drawing […]

Neat
World wide wind potential (using only conventional wind technology) exceeds our current energy needs by many times. However, that is merely the potential of wind near the ground, at 80 to 100 meters.Most wind energy is in the jet stream, miles over our heads. No one is going to build a tower that high to support a wind turbine; cost alone would prohibit that. But we can use flying energy generators -- turbines supported by kites or balloons or what amounts to stationary helicopters. The latter technology (stationary helicopters supporting wind turbines) has actually been demonstrated briefly, and has been claimed in peer reviewed research to be ready for commercial implementation (PDF). Questions like net energy, metal fatigue, stability, transformers and power loss have all been answered -- at least on paper. (Net energy at really high altitudes is higher than with either kites or helium balloons -- due to wasted energy on the downward part of the cycle with kite systems, and drag with balloon systems.)
According to the corporation developing this technology, Sky WindPower, they can put together a system out of commercially available products that will provide wind electricity (at a profit) for 2 cents per kWh -- competitive with current fossil fuel generation.

Don’t fight it
Energy wonk Robert McLeod has long post filled with statistics and graphs, arguing a simple point: if historical trends continue, solar power is going to dominate. Soon. (You’ll recognize this as substantially similar to the argument made by solar booster Travis Bradford.) If you’re into statistics and graphs, read the whole thing. If not, here […]

Eyes wide shut toward global collapse?
Ecological Footprint, Energy Consumption, and the Looming Collapse:
This article explores dynamic relations governing population growth, resource depletion, and world economics by means of a few simple modeling and simulation exercises. To this end, we start out by exploring the concept of an ecological footprint, representing the amount of land that a person needs to produce everything that he or she consumes: food, clothing, energy, shelter, the tools that are needed to make the clothing, etc. and place it in relation with the human development index, a measure of the quality of life of an individual. We then relate the ecological footprint to the per capita energy consumption. This discussion serves to provide a quantitative understanding of the limited resources that are at our disposal.
The article continues by exploring the dangers and seductions of exponential growth, and uses a system dynamics approach to illustrate why we are moving at a rapid pace toward global collapse with our eyes wide shut.
The article ends by discussing what we would need to do in order to avoid the looming collapse. -
Smells Like Progress
As climate summit continues, fed-up mayors unveil actual plans They cover 1 percent of the Earth’s surface, but the world’s cities spew 80 percent of greenhouse-gas emissions — and 180 percent of climate-action plans. “Where national governments can’t or won’t lead, cities will,” said Toronto Mayor David Miller at the C40 Large Cities Climate Summit […]
