>>Bodman tells Congress: No silver bullets in energy
June 27, 2008, 8:13 pm
Filed under: Policy

Secretary of Energy Samuel Bodman testified in Congress today on energy security issues. Read the full text here.

nullHe summed it up by saying that DOE is

advancing the effort to curb America’s dependence on fossil fuels and reduce GHG emissions. These efforts are expected to eventually help mitigate the effects high energy prices have on the American taxpayer. There is no silver bullet that will immediately solve our energy challenges, or drastically reduce costs at the gas pump. But we need to work together and answer the President’s call to increase domestic exploration, expand our nuclear infrastructure as well as solve our long-term nuclear waste storage challenge.

Along the way he made brief mention of research support in renewable energy and coal-plant carbon sequestration. No mention of the freeze on renewable power plant permits on federal land.>>



>>BLM imposes moratorium on renewable power plants
June 27, 2008, 7:06 pm
Filed under: Policy

About three weeks ago, we reported that the Bureau of Land Management was snowed under with permit applications for new solar and geothermal plants in California and Nevada, and wanted a moratorium on new applications.

Now they’ve got it. According to today’s New York Times, applications are frozen for study — which will take up to two years. 130 applications submitted before the end of May will be processed. BLM says they want to look at the potential impact on habitat, water use and potential for land restoration after the plant closes some decades on.

This is not good news. Climate Progress concludes that it’s a sly way for the lame duck Bush administration to stall renewable energy work on federal lands, while oil and natural gas drilling proceed elsewhere.

The first victims of this policy, if it stands, will be start-up renewable energy developers. But it may also put public utility companies at risk of coming up short, and late, in meeting RPS deadlines.

This may shape up to be a fight between clean-energy advocates on one hand and habitat-preservation advocates on the other, between the Feds on one side and state governments on the other.

Congress should step in on this one, right now. Rant to your legislators.



>>CIBC: $7 gas, stagflation in our future
June 26, 2008, 8:14 pm
Filed under: Fossil fuel

CIBC World Markets, the Canadian-based international bank, has just released two very sobering forecasts.

Getting Off the Road: Adjusting to $7 Gas in America predicts $200-per-barrel oil by 2010. By 2012 Americans will cut their miles driven by 15%, as 57 million commuters crowd onto overtaxed public transport systems. Sales of oversize vehicles — SUVs and light trucks — will plummet 50%.

What will that do to the economy? Oil and Growth: That 70s Show Rerun predicts it will drive inflation and therefore higher interest rates. The result will limit real annual growth to about 1% — what economists call stagflation, where unemployment rates and inflation rates drive a rising “misery index.”

The only bright spot will be continued spectacular growth in renewable energy and electric transport. Better invest now.



>>Obama outlines energy plans
June 25, 2008, 3:21 pm
Filed under: Policy

Barack Obama gave a speech on energy policy yesterday in Las Vegas. In it, he promised to

  • tax oil companies to pay for a $1000 tax rebate to working Americans.
  • enforce CAFE standards and help auto companies meet their efficiency targets.
  • invest $150 billion in renewable energy.
  • impose fees for unused drilling leases.

Here’s the full text of the speech:

I want to start by thanking the folks here at Springs Preserve for the wonderful tour we just had. What we are seeing here — from the solar panels that power this facility to the Bombard workers who built it — is that a green, renewable energy economy isn’t some pie-in-the-sky, far-off future, it is now. It is creating jobs, now. It is providing cheap alternatives to $140-a-barrel oil, now. And it can create millions of additional jobs and entire new industries if we act now.

All across the country, local leaders and entrepreneurs and small business owners are providing the innovation and initiative needed to make this transformation possible. In Pennsylvania, an old steel mill has become the home of a new wind turbine factory because of the state’s push for renewable portfolio standards that require the production of more alternative energy. Wisconsin is poised to gain more than 14,000 jobs at existing manufacturing facilities because of its investment in wind power. Where we’re standing in Southern Nevada happens to be one of the best sources for the generation of solar power in the world. Next week, our friend and Senate Majority Leader Harry Reid will come here to cut the ribbon on a new thermal solar technology plant. And between solar, wind, and geothermal energy, this state could create upwards of 80,000 new jobs by 2025.

The possibilities of renewable energy are limitless. But to truly harness its potential, we urgently need real leadership from Washington – leadership that has been missing for decades. We have been talking about energy independence since Americans were waiting in gas lines during the 1970s. We’ve heard promises about it in every State of the Union for the last three decades. But each and every year, we become more, not less, addicted to oil – a 19th century fossil fuel that is dirty, dwindling, and dangerously expensive. Why?

It isn’t because the resources and technology aren’t there. We know this because countries like Spain, Germany, and Japan have already leapt ahead of us when it comes to renewable energy technology. Germany, a country as cloudy as the Pacific Northwest, is now a world leader in the solar power industry and the quarter million new jobs it has created. In less than eight years, before we’d ever see a drop of oil from offshore drilling, they have doubled their renewable energy output. And they did it by using technology that, in some cases, was paid for by the American people through our own Research and Development tax credits. The difference is, their government harnessed that technology by providing the necessary investments and incentives to jumpstart a renewable energy industry. Washington hasn’t done that.

What Washington has done is what Washington always does – it’s peddled false promises, irresponsible policy, and cheap gimmicks that might get politicians through the next election, but won’t lead America toward the next generation of renewable energy. And now we’re paying the price. Now we’ve fallen behind the rest of the world. Now we’re forced to beg Saudi Arabia for more oil. Now we’re facing gas prices over $4 a gallon – gas prices that are decimating the savings of families who are already struggling in this economy. Like the man I met in Pennsylvania who lost his job and couldn’t even afford the gas to drive around and look for a new one. That’s how badly folks are hurting. That’s how badly Washington has failed.

For decades, John McCain has been a part of this failure in Washington. Yes, he has gone further than some in his party in speaking out on climate change. And that is commendable. But time and time again, he has opposed investing in the alternative sources of energy that have helped fuel some of the very same projects and businesses he’s highlighting in this campaign. He’s voted against biofuels. Against solar power. Against wind power. Against a 2005 energy bill that represented the largest ever investment in renewable sources of energy – a bill that Senator McCain’s own campaign co-chair, called “the biggest legislative breakthrough we’ve had” since he’s been in the Senate. That bill certainly wasn’t perfect – it contained irresponsible tax breaks for oil companies that I consistently opposed, and that I will repeal as President. But the tax credits in that bill contributed to wind power growing 45% last year, the sharpest rise in decades. If John McCain had his way, those tax credits wouldn’t exist. And if we don’t renew key tax incentives for alternative energy production – tax incentives that John McCain opposed continuing – we could lose up to 116,000 green jobs and $19 billion in investment just next year. And now he’s talking about a tax credit for more efficient cars even though he helped George Bush block these credits twice in the last year. Continue reading



>>McCain backs domestic drilling
June 23, 2008, 6:46 pm
Filed under: Policy

In a speech last Tuesday in Houston, to an audience of oil executives, John McCain outlined an energy policy He said

  • Federal regulations should defer to states regarding the opening of offshore drilling leases and the opening of ANWR for oil exploitation.
  • The U.S. should fast-track construction of 100 new nuclear plants.
  • Tax incentives should support renewable energy sources.

For a good summary of the talk, see the Houston Chronicle’s coverage.



>>Times: Obama has ties to ethanol interests
June 23, 2008, 5:09 pm
Filed under: Policy

A front page story in today’s New York Times carries the headline “Obama Camp Closely Linked With Ethanol.”

Right now, that apparently means corn ethanol. Illinois is the second-largest producer of corn, after Iowa. Sen. Obama has expressed support for the tariffs that keep Brazilian ethanol out of the U.S. market. The article says nothing about the future of domestic cane ethanol.

Corn ethanol may turn out to be a bridge technology to renewable feedstocks that are dramatically less dependent on fossil-based fertilizers, along with fossil cultivation, transport and processing fuels. Meanwhile, it’s nice to know that Midwestern polticians are crossing that bridge.

Sunday’s Op-Ed page carried a rant from Thomas Friedman that’s well worth reading. He says that the Bush energy plan is to intensify our addiction to oil. He writes:

Actually, it’s more sophisticated than that: Get Saudi Arabia, our chief oil pusher, to up our dosage for a little while and bring down the oil price just enough so the renewable energy alternatives can’t totally take off. Then try to strong arm Congress into lifting the ban on drilling offshore and in the Arctic National Wildlife Refuge.



>>GE says wind farms pay off their own tax incentives
June 18, 2008, 3:05 pm
Filed under: Policy

General Electric this morning reported that wind farms built in 2007 generate more than enough in tax revenues to offset the tax incentives that got them built.

A report released at a renewable energy finance forum in New York, the GE Energy Financial Services Study says that Congress should stop dithering over how to pay for renewable energy tax credits, because they’re already paid for. The report estimates that “wind energy projects that began operating in 2007 have a positive net present value of $250 million to the US Treasury,” over and above any tax credits.

It looks like a canny end-run around the current impasse in Congress. House Democrats want investment and production tax credits extended beyond Dec. 31, but want the cost of the program paid for by rolling back subsidies and tax loopholes for other businesses. Republicans refuse to allow a vote on any program that would cut back subsidies and tax loopholes for other businesses.

A big part of the reason Democrats insist on a pay-for is that the Bush tax cuts have no pay-for. If they can enforce an across-the-board pay-for policy, it’s a powerful argument for allowing the Bush tax cuts to expire. And that, in a new Congress, would be an important first step toward balancing future budgets.

The General Electric argument that renewable incentives pay for themselves might be accepted by Republicans, who often talk about wanting “a clean bill” — that is, a bill without offsets or pay-fors. It’s less likely to be accepted by Democrats, who may view it as a trojan horse on behalf of renewed tax cuts.



>>California plant to combine CSP with biomass
June 16, 2008, 3:20 pm
Filed under: Utilities

According to the San Jose Mercury News, Pacific Gas & Electric has signed a deal to buy 106.8 megawatts of power from San Joaquin Solar, a subsidiary of Martifer Renewables, a Portuguese company. Martifer plans to build a concentrating solar plant near Coalinga, and will use a quarter-million tons of agricultural waste annually as a biomass fuel to extend power generation beyond sunset.

The biomass hybrid approach may be the first of its kind. Previously, hybrid CSP plants have burned natural gas to keep the electricity flowing at night. Fresno County is said to produce 2 million tons of agricultural waste annually — cattle manure, grass clippings and the non-edible stalks and hulls from grain crops.

The plant is scheduled to produce power in 2011.



>>Mastering mileage
June 11, 2008, 5:33 pm
Filed under: Fossil fuel

As gasoline prices inch beyond $4 per gallon nationwide, the mainstream press has taken notice of hypermilers like Wayne Gerdes — obsessives who squeeze fuel for every inch it’s worth. NPR and The New York Times have done pieces this week. These folks boast of getting over 100 miles per gallon on the highway in a Prius, or over 200 in an old Honda Insight.

The techniques? Obviously, the car should be well-tuned, with properly-inflated tires. You want to keep engine revs low and speed under the limit. It helps a lot to kill the engine at stoplights and in traffic gridlock (hybrids do this automatically).

More questionable moves, in terms of safety and legality: rolling stops at stop signs, coasting downhill in neutral and with the engine off, cruising through corners without braking, drafting trucks and buses.

I’d love to get 100 mpg, but I can’t run out and buy a Prius. I got 32 mpg on the last tank in the ’96 Subaru, which is pretty good for a car with all-wheel drive. That tank included a 150-mile round trip mostly on highways and several days of commuting around town. In town I turn the engine off at stop lights (during daylight hours only) and upshift early to keep revs under 2000 rpm, or even 1500. On the highway I’ll admit to coasting in neutral (but with the engine idling). I wouldn’t draft a big truck (truckers hate that) but I do believe in reducing drag due to air resistance. To monitor drag, I’ve installed an airspeed indicator, with the pitot tube protruding through the grill. I feel less guilty about high speed if I know I have a tailwind.

If I were really serious about this I’d put in a manifold pressure gauge, which tells more or less directly how much mass (of fuel-air mixture) you’re pushing into the engine at any moment.
