Biofuels Aren’t Green?

At least that’s what a new study says. I think it paints with a pretty broad brush, because I do in fact think some can be green. But a new study published in Science, echoing the themes of an earlier study I highlighted, concludes that almost all biofuels in use today will increase greenhouse gas emissions. The Wall Street Journal reports: Biofuels May Hinder Antiglobal-Warming Efforts While the U.S. and others race to expand the use and production of biofuels, two new studies suggest these gasoline alternatives actually will increase carbon-dioxide levels. A study published in the latest issue of Science finds that corn-based ethanol, a type of biofuel pushed heavily in the U.S., will nearly double the output of… Continue»

Instant Energy Savings

The latest issue of Mother Earth News has an interesting article on ideas to reduce your carbon footprint: 8 Easy Projects for Instant Energy Savings Some of them are going to be familiar to everyone here, but others may not be. This is what the author achieved: Here are the details: We cut our total energy use from 93,000 kilowatt hours (kWh) per year to 38,000 kWh per year. This is saving us $4,500 per year in energy costs, and has reduced our carbon dioxide (CO2) emissions by 17 tons! Our rate of return on the money we invested in this program is more than 50 percent — tax free. Altogether, we took on 22 different projects, including two solar… Continue»

FutureGen Project Stopped

The FutureGen Project, a clean coal demonstration plant that would have included carbon capture and sequestration (and was #8 on My Top Energy Stories of 2007) has been cancelled. The culprit? Cost overruns of about 80%, and a lot of competing projects. It turns out that carbon sequestration isn’t cheap, and the DOE decided the price tag was too high for this project: U.S. pulls the plug on funding for FutureGen The Department of Energy on Wednesday officially quashed a $1.8 billion clean-coal project slated for central Illinois, leaving the experimental venture to capture carbon emissions dependent on Congress for survival. The FutureGen Industrial Alliance was cooperating with the Energy Department to develop a coal-fired power plant designed to gasify… Continue»

Now That’s an About Face!

It’s been almost two years now that 60 Minutes did a special on ethanol, in which Dan Rather was just bubbly with enthusiasm. He had as a guest Berkeley Professor Dan Kammen, who heads up Berkeley’s Renewable and Appropriate Energy Laboratory (RAEL). (I frequently see visitors from RAEL showing up on my site meter). Anyway, Professor Kammen talked up the virtues of ethanol with Dan Rather, and also spoke very positively on ethanol in this article: Ethanol can replace gasoline with significant energy savings, comparable impact on greenhouse gases Boy, that takes me back. You have to love the appeal to authority: Knowledgeable venture capitalists already are putting money behind ethanol and cellulosic technology, as witnessed by recent investments by… Continue»

Why We Will Never Address Global Warming

I made the comment below recently in the discussion following an essay: If you put it to a popular vote, and people learned that GHG emissions could be arrested (hypothetically) if they were willing to pay $7/gallon of gasoline, what percentage would vote for that? My guess is that it would be well less than 20%, implying that GW concerns will give way to economic concerns. At one time I was really worried about Global Warming. And at the risk of starting another Global Warming debate here (one that I don’t have time to participate in), my position is that the scientific consensus backs the hypothesis that human activity is contributing to Global Warming. I am not an atmospheric scientist,… Continue»

FTC Investigates Carbon Offsets

I am still on the road, but wanted to quickly stick something fresh up for discussion. I have long been suspicious of the whole carbon offsets business (and frankly, it reminds me of buying indulgences). The FTC apparently shares similar concerns: F.T.C. Asks if Carbon-Offset Money Is Well Spent Corporations and shoppers in the United States spent more than $54 million last year on carbon offset credits toward tree planting, wind farms, solar plants and other projects to balance the emissions created by, say, using a laptop computer or flying on a jet. But where exactly is that money going? The Federal Trade Commission, which regulates advertising claims, raised the question Tuesday in its first hearing in a series on… Continue»

50 people who could save the planet

(Also, a Barack Obama discussion in the comments following this essay). The Guardian has just published a list of 50 people who may save us all from “stranded polar bears, melting glaciers, dried-out rivers and flooding on a horrific scale.” Some of the names certainly belong on the list, and some left me shaking my head: 50 people who could save the planet It is pretty clear to me that the author couldn’t really distinguish between what is complete hype, and what may actually work. Some will get a kick out of seeing Amory Lovins on the list. Especially in light of this article in Energy Tribune. Leonardo DiCaprio is also on the list, but I think he is a… Continue»

Al Gore Makes Amends

Better late than never: Gore makes Nashville home more ‘green’ NASHVILLE, Tennessee (AP) — Al Gore, who was criticized for high electric bills at his Tennessee mansion, has completed a host of improvements to make the home more energy efficient, and a building-industry group has praised the house as one of the nation’s most environmentally friendly. The former vice president has installed solar panels, a rainwater-collection system and geothermal heating. He also replaced all incandescent lights with compact fluorescent or light-emitting diode bulbs — even on his Christmas tree. “One of the things that is tremendously powerful about what the Gores have done is demonstrate that you can take a home that was a dog, an absolute energy pig, and… Continue»

Al Takes the Train

Because I gave Al Gore such a hard time over his electric bill, I thought I would mention this story. Gore is in Oslo to accept the Nobel Peace Price, and he took public transportation from the airport: Gore in Norway to get Nobel Peace Prize OSLO, Norway – Former Vice President Al Gore arrived in Oslo on Friday to accept the Nobel Peace Prize he shared for the campaign against global warming, and shunned the traditional airport motorcade in favor of climate-friendly public transport. Before his arrival with his wife Tipper, Gore informed his hosts that he would not need the traditional motorcade from the airport, preferring to take the high-speed and environmentally friendly airport train and then walking… Continue»

Renewable Energy: “Expensive and Impractical”

At least that’s the conclusion of the present government in the UK: Labour’s plan to abandon renewable energy targets Ministers are planning a U-turn on Britain’s pledges to combat climate change that “effectively abolishes” its targets to rapidly expand the use of renewable energy sources such as wind and solar power. Leaked documents seen by the Guardian show that Gordon Brown will be advised today that the target Tony Blair signed up to this year for 20% of all European energy to come from renewable sources by 2020 is expensive and faces “severe practical difficulties”. According to the papers, John Hutton, the secretary of state for business, will tell Mr. Brown that Britain should work with Poland and other governments… Continue»
