A new study with intriguing conclusions

This is interesting. One of the big dings on a carbon tax has been that it’s regressive — it will hurt the poor (who pay a higher percentage of their income for energy) more than the rich. But according to a new study, it ain’t so: But the new study, based on data from Indonesia, […]

Get Your Vacuum Cleaner Ready

Southern Ocean losing ability to soak up carbon dioxide, researchers say If you’re counting on the seas to soak up excess emissions and get us out of this climate mess, you might need a new plan. Scientists say Antarctica’s Southern Ocean, a whopper of a “carbon sink,” is losing its ability to absorb more carbon […]

Massachusetts is going to blow

The electrical grid in Massachusetts is getting ready to blow: Documents obtained by the Herald show more than 12,000 transformers from Attleboro to Ayer are operating at above 200 percent capacity, with some as high as 900 percent over design standards. Union officials, who last night reached an agreement in contract talks with National Grid, […]

New Scientist’s troll-b-gone

If our How to Talk to a Climate Skeptic guide doesn’t whet your appetite for debunkery, head on over to New Scientist, which has a new series taking on “the 26 most common climate myths and misconceptions.” Some are familiar to devotees of our guide — they predicted global cooling in the ’70s! — but […]

A123 introduces new battery

From the Energy Blog:

A123 Systems today introduced its 32-series Nanophosphate^TM 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 […]
