Congress Actually Ends Taxpayer Funding Of Ethanol Subsidies
Yay!
I would support subsidies for actual “green” energy sources, however, ethanol is not one of those sources. Not only is it a net-energy loss (takes more energy to produce than what you get out) but…
“Using corn is the least productive way to make ethanol, at roughly 300 gallons per acre of feedstock. The Brazilian ethanol industry gets twice as many gallons per acre using sugar cane, and other feedstocks like switchgrass have been projected to produce up to 1,200 gallons per acre.”
So now, where is the investment in switchgrass ethanol?
Or perhaps we put a 50 cents / gallon tax on petroleum based road fuels?

This bugs me:
Volvo is laying claim to the first production diesel plug-in hybrid title with the company’s new V60. The vehicle makes use of a five-cylinder 2.4-liter turbo diesel engine with 215 horsepower and 325 pound-feet of torque coupled to a six-speed automatic transmission as well as an electric motor good for up to 70 horsepower and 147 pound-feet of torque. The forced-induction internal combustion engine puts power to the front wheels while the electric motor feeds its grunt to the rear. An 11.2-kWh lithium-ion battery pack fields power storage duties, and Volvo says the V60 plug-in diesel hybrid can travel up to 32 miles on all-electric power with a single charge.
Why can’t we buy this car in America!
As with most plug-ins, charge times vary depending on the available current, but Volvo claims the V60 can top off its cells in as little as 3.5 hours on a 16-amp line. Interestingly enough, the vehicle allows the driver to chose between three drive modes. Pure mode relies on the electric motor as much as possible while Hybrid mode splits the difference between the diesel mill and the electric motor. Finally, Power mode calls on the full 285 horsepower and 362 pound-feet of torque for the most driving enjoyment. Volvo says the V60 diesel plug-in hybrid can kick up to 60 mph in 6.2 seconds in Power mode.
What? It goes 0-60 in 6.2 seconds? It’s a plug-in hybrid AWD diesel that can go 30 miles on electric only?

In a post-election news conference, President Obama noted that it was doubtful that Congress would do anything to address global warming “this year or next year or the year after.â€
Maybe the year after that?

Another reason for the lack of recent blogging is my mild depression regarding all things government. Health care: underwhelmed. Financial regulations: meh. More tea party crazies in government: Positively scary.
And then this…
We’re Gonna Be Sorry
I could blame Republicans for the fact that not one G.O.P. senator indicated a willingness to vote for a bill that would put the slightest price on carbon. I could blame the Democratic senators who were also waffling. I could blame President Obama for his disappearing act on energy and spending more time reading the polls than changing the polls. I could blame the Chamber of Commerce and the fossil-fuel lobby for spending bags of money to subvert this bill. But the truth is, the public, confused and stressed by the last two years, never got mobilized to press for this legislation. We will regret it.

Friedman’s op-ed actually opened up a new line of reasoning I hadn’t considered before. What exactly would the motivation be for climatologists to fake global-warming? If someone could answer that for me, I’d love to know.

The Pratt House project is an example of a burgeoning movement in the building industry. With the growing concern over the environment and energy, builders and architects are devising ways to dramatically cut the energy use in people’s homes, for both new construction and retrofits. In the U.S., all buildings represent about half of greenhouse gas emissions, according to the U.S. Green Building Council.
Via: This Green Home Will Heat Itself
At some point in the future, we’re going to either convert or build a new house that is passively heated and cooled. All of the research I can find so far says that we will need an auxiliary heat source, but that we should be able to achieve a very energy efficient home in minnesota.
