Plug-in Hybrids May Not Go Mainstream, Toyota Says
mattnyc99 writes "Honda's challenger to the Prius — the Insight hybrid that we discussed so lividly a month ago — got its official unveiling today at the Paris auto show, with insiders confirming it would be cheaper than the world's most popular 'green' car while still hitting the same fuel-efficiency range. But the hybrid-electric showdown comes in the midst of a sudden rethink by Toyota about plug-in hybrids. Apparently all the recent hype — over the production version of the Chevy Volt, plus Chrysler's new electric trio and even the cool new Pininfarina EV also unveiled today — has execs from the world's number one automaker, and alt-fuel experts, questioning how many people will really buy electric cars, whether people will really charge them at night to keep the grid clear, whether batteries will make them too expensive and more.

Dude, the Department of Energy says you're wrong:

One common critique of an electric car revolution is that the increased energy demand might just lead to the generation of new power plants, negating some of the cars' positive environmental benefits. Well, according to a new study by the U.S. Department of Energy, those critiques are misguided. The study shows 84% of the 198 million cars, light trucks and SUVs on America's roads could be fueled by the existing energy infrastructure if switched to plug-in hybrid vehicles. When you add vans and other vehicles in the "light duty fleet," 73% of the 217 million vehicles could be powered with the power plants we have in place today. In switching from 6.5 million barrels of oil every day to electric cars fueled by off-peak power production, the study estimates a reduction of greenhouse gases by 27%.
Even with America's current power mix, with a heavy dose of coal power generation, electric vehicles are show to reduce total greenhouse emissions, however the picture isn't all rosy. The Department of Energy study also points to an increase in total particulate emissions with the grid pumping power all night. This, however, is much easier to tackle than petroleum-based pollution. As alternative energy gains a greater share of the American power pie chart, we can look for less particulate emissions as well. In the meantime, check to see if your power company offers green power or try to generate your own. Then, when you get your electric speedster, you can rev it up without worry.
Emphasis mine.
Winds farms don't scale, and do affect the environment some. Hydro doesn't scale, and building new dams just to make power certainly screws with the local environment. Geothermal doesn't come anywhere close to scaling, and may affect the environment in surprising ways.
Right now, nuclear is the only scalable choice for clean power. Eventually, solar will work too, but since solar isn't reliable it will never be a primary power source until someone invents a magic battery. However, with a magic battery, solar power is "fusion power too cheap to meter" so hopefully somone makes that happen.
ULEV cars are *far* cleaner than existing coal plants, and may be cleaner than a pure-electric car depending on where you live.
"Serial" hybrids (motor turns generator, not axel) are a fantastic idea, because they allow turbine engines to replace reciprocating cylinder engines. Gas turbines can be may much *more* efficient than 4-stroke engines, because you can make good use of the waste heat. I think the theoretical limit for a turbine is double tht of a 4-stroke - anyone know for sure?
Socialism: a lie told by totalitarians and believed by fools.
I often wonder why Toyota pulled the plugin capabilities from the Prius, the hardware is there in the first generation models, my friend has a kit to convert his once the battery warranty is up and there's not a lot to it, just a plug that attaches to some internal terminals and a chip mod to delay the engine warm-up until the battery is much further drained.

"Environmentalists don't care where Coal, Gas, or Oil waste goes"
Wow. That's one of the most stunningly ignorant statements I've read in a long time. Seriously. Almost every environmental political and legal group is constantly working on issues related to air-pollution from power plants.
You are right in that it's hypocritical to have higher standards for nuclear power than the other power sources. But I'd prefer to bring our standards up, rather than lower nuclear's standards to that of coal. The way most coal powered plants are run it'd look like Chernobyl around the plant, and they'd store the waste in big piles out in the open.
