>>China retrenches, commodity prices fall
November 26, 2008, 8:56 pm
Filed under: Events

Last month China’s electricity production fell, for the first time in years. Because American and European consumers have stopped buying imported manufactures, China’s industrial production is off sharply, with shut-downs in steel plants and other metal-smelting operations. To replace the foreign orders, China will pump almost $600 billion into their domestic consumer economy. They can do this more easily than we can because they actually have the cash. When we do a big stimulus package, we have to borrow it. Most of it from China.

One bright spot in all of this is that the cost of important commodities has plunged, and is likely to drop further. Copper and aluminum for electrical wiring, steel for powerline towers, even lead and lithium for whopping big batteries, are all going to be much cheaper for a few years. Now is the time to start building out that new smart grid and ramping up electric vehicle production.

On my way to work this morning I passed a gas station selling unleaded regular for $1.74. This makes me worry that folks are going to climb back into their SUVs. The polls say otherwise: Consumers are saving money everywhere they can now. The AAA forecasts that Thanksgiving travel will be down this weekend: air travel down 7.2%, road travel down 1.4%. If Americans drive over the river and through the woods in the smaller car, maybe gasoline purchases will drop 2% or 3% relative to Thanksgiving 2007.

My advice: Stay home. Watch football. Eat more turkey, and walk it off.



>>Economic chaos may delay carbon-reduction plans
November 25, 2008, 6:18 pm
Filed under: Climate science, Policy

Yesterday’s New York Times contained a sobering assessment by Elizabeth Rosenthal on the impact of global economic turmoil on any progress toward a low-carbon energy future.

While Western governments seem determined to adopt meaningful carbon caps, she points out, several significant renewable-energy projects have already been stalled by the recent drop in the price of oil. One example: On Nov. 12, T. Boone Pickens announced he’s putting his West Texas wind farm project on hold until energy prices rebound.

Serious recessions have usually suppressed energy use. This time around, the serious slow-down in Chinese industrial production will forestall the construction of new coal plants there, while reduced driving worldwide should cut carbon emissions temporarily.

Nonetheless, according to Dr. James Hansen and his research team, the carbon clock is at midnight.



>>Adventures in living renewably

An update from the do-it-yourself scrounger:

Electric commuting: I now have a couple of months’ experience riding the Yamavolt electric motorcycle conversion to work and around town. The bike runs very nicely, thank you.

Real-world experience suggests that, in future, recharging infrastructure is going to be critical. I have no trouble riding to work and back because, thanks to our set-up at the office, I can recharge the bike in the warehouse. But running errands downtown is a problem, because I can’t recharge while shopping. When this set of batteries poops out I’ll invest in a NiMH pack to double the range.

Charging overnight

Charging overnight

If I worked in an office without a recharging outlet in the parking structure, or if I lived in an apartment building, electric commuting would be sketchy. I’d have to run a very long extension cord out some window and out to the parking lot.

Even with my own parking slot with a dedicated recharging outlet, I’d want the vehicle to have at least three times the necessary range — 30 miles for a 10-mile commute — to assure being able to get home if charging weren’t available at work. In future, every parking meter and garage space ought to be a charging station. In 20 years, parking vendors should be retailing kilowatt hours instead of renting tiny patches of real estate on an hourly basis.

If I were in the inverter/transformer business, I’d be gearing up now to serve the future auto-recharging market. If I were an architect, I’d be figuring out how to wire parking garages for overhead charging circuity.

Solar water heating: I made progress on my cobbled-up solar water-heating system over the weekend. The Butler Sun Systems heat exchanger wand was a ten-minute job to install in my water heater tank. Just open the 230-volt circuit breaker, shut the cold-water feed valve, drain a few gallons out the bottom of the tank through a garden hose, and disconnect the one-inch hot-water-out line. That revealed a collar inside the tank measuring 3/4″ across, too narrow to admit the heat exchanger wand, which has an outside diameter of 7/8″.  I broached the thin steel collar with a 7/8″ hole saw, in about 10 seconds flat.  Used the hole saw instead of a 7/8″ bit because its smooth sides wouldn’t damage the water-out threads. The wand then slipped straight in and snugged down quickly. I had hot water again in three minutes.

The next step was to pressure-test the 30-year-old collector boxes on the roof. I bought these at salvage a couple of years ago for $30 each, and they’re a standard 4’x8′ insulated-box design with copper fin tubing inside and tempered glass outside. I have two of them canted 40 degrees from vertical facing dead south, and soldered them together last week. I rigged plastic tubing to the four outlets with a pressure gauge, a ball valve and a fitting to take the garden hose. When I turned on the water, the system filled up quickly. I closed the valve and checked the gauge: it showed 130 lb, the city water pressure.

90px-old_faithful_geyser_calistoga_californiaBut the water heated up quickly and at 140 lb. one of the soldered joints between the two panels began to weep. Then it bubbled. Then one of the plastic tubes blew off at the top, with a sound like a very large champagne cork headed for orbit, and a geyser of steam shot out.

You should have been there.

I drained the system into a five-gallon bucket and found I’ll need about three gallons of propylene glycol.

Next step is to separate the panels and connect them again with solder-free unions. Soldering those joints is tough for two reasons: They butt right up against the aluminum frame, so it’s hard to get at them; and the internal fin-tubing functions as a fabulous heat sink. It takes a long time and a hot flame to make the solder flow evenly. The end of the copper pipe sags and doesn’t want to stay round.

Anyway, it’s nice to know that this system will boil water even on a late-November day in Colorado.

Onward!



>>Obama moves green agenda forward
November 24, 2008, 4:38 pm
Filed under: Policy

The weekend saw plenty of frightening economic news, but the president-elect dropped an early Christmas gift on renewable energy.

On Saturday, Barack Obama outlined an economic stimulus package that will invest billions to rebuild roads, bridges and schools — and to develop renewable energy. The projects are intended to save and create 2.5 million jobs over the next two years. He was expected to provide more details on Monday when he presents his team of economic officials and advisers.

What this means for renewables is that important government investments will be moved up for congressional action in January and treated as part of the administration’s first-priority efforts, rather than proposed later as a separate energy-policy package.

>>Bay Area cities earmark $1bn to be EV capital of U.S.
November 21, 2008, 5:11 pm
Filed under: Policy, Transport

Press release, 11/20/08: Today, Mayor Gavin Newsom, San Jose Mayor Chuck Reed and Oakland Mayor Ron Dellums announced a nine-step policy plan for transforming the Bay Area into the “Electric Vehicle (EV) Capital of the U.S.” In conjunction with the news, Better Place, a global electric transportation company, announced that it would enter the U.S. market with California as its first state, beginning in the Bay Area.

“Our aim is to make the Bay Area — and eventually California — the electric vehicle capital of the U.S.,” said

San Francisco Mayor Gavin Newsom.

Commercial availability of electric cars is targeted to begin in 2012, and Better Place estimates its network investment in the Bay Area will total $1 billion when the system is fully deployed. The three Mayors said they welcomed Better Place’s announcement and anticipate many other EV companies will focus on the Bay Area as a top-priority market.

“In these times, it is critical that we identify solutions to address both our economic and environmental challenges,” said Speaker of the House Nancy Pelosi. “Promoting the use of electric vehicles will help forward our nation’s goals to achieve energy independence, to protect the environment by reducing greenhouse gas emissions and to boost the economy by providing jobs in an emerging manufacturing sector.”

Joined by Governor Arnold Schwarzenegger’s special advisor David Crane, the Mayors announced that they would take unprecedented action beginning in December to work with the region’s cities, counties, regional governmental organizations and private sector partners to position the region’s economic and environmental future around electric transportation.

“California is already a world leader in fighting global warming and promoting renewable energy,” said Governor Schwarzenegger. “This type of public-private partnership is exactly what I envisioned when we created the first ever low carbon fuel standard and when the state enacted the zero emissions vehicle program.This partnership is proof that by working together, we can achieve our goals of creating a healthier planet while boosting our economy at the same time.”

The Mayors announced policies that they will advance, beginning in December:

  • Expedited permitting and installation of electric vehicle charging outlets at homes, business, parking lots, and other buildings throughout the Bay Area;
  • Incentives for employers to install EV charging systems in their workplace and provide similar incentives to parking facilities and other locations where EV charging stations can be installed;
  • Harmonize local regulations and standards across the region that govern EV infrastructure to achieve regulatory consistency for EV companies as well as expanded range for EV consumers;
  • Establish common government programs that promote the purchase of EVs;
  • Link EV programs and infrastructure to regional transit and air quality programs;
  • Establish programs for aggressive pooled-purchase orders for EVs in municipal, state government and private sector fleets and future commitment of purchasing preference for EV vehicles;
  • Expedited permitting and approval for facilities that provide extended-range driving capability for EVs in the region through battery exchange locations or fast-charging;
  • Identify and secure suitable standard (110V) electric outlets for charging low voltage EVs in every government building in 2009; and
  • Identify roll-out plan for placement of 220V EV charging equipment throughout each city including city
    parking lots and curbside parking.

The Mayors said they will work with other cities throughout the region, regional government organizations such as the Bay Area Air Quality Management District, Metropolitan Transportation Authority, and Association of Bay Area Governments, as well as many private sector partners, including the members of the Bay Area Council and Silicon Valley Leadership Group.

>>The world turned upside down
November 20, 2008, 9:27 pm
Filed under: Investing, Transport

In a press release on Wednesday, the German photovoltaic manufacturer SolarWorld offered to buy the Opel division from General Motors for $1.25 billion. GM promptly scorned the offer.

Opel makes very efficient cars and trucks. The very existence of Opel technology legitimizes GM’s request for a share of the auto industry’s $25 billion federal loan to cover retooling costs to build smaller, fuel-sipping cars. GM wouldn’t be near bankruptcy today if it had begun two years ago to replicate the Opel tooling in Detroit. Opel is in fact the future of the company, so I can understand why they’d think $1.25 billion is too little.

On the other hand, GM’s stock sold for under $2.80 on Thursday. That’s a market cap of $1.9 billion. If SolarWorld is serious about the automobile business, it could buy a controlling share of GM stock for under $1 billion, put the American divisions into bankruptcy, liquidate most of it but keep enough of the infrastructure to make and sell Opels rebranded as Chevrolets.



>>SUV to FFFPHEV: A bronx cheer for detroit
November 18, 2008, 3:48 pm
Filed under: Policy, Transport

With its request for another $25 billion bail-out, on top of the $25 billion they’ve already been promised to help with small-engine retooling, Detroit’s travails have turned into a black comedy. We’re asking the big car companies to improve CAFE standards and make plug-in hybrid vehicles. The infuriating thing is that they already build efficient small cars for sale in Europe, Brazil, Korea and China. Why not build those cars here? They want us to pay the costs of conversion, up front, because they don’t believe people will buy small cars. Right now they’re justified in believing that we won’t buy cars at all, at least not from Detroit.

In December, 1941, Detroit had just introduced the 1942 model cars. After Pearl Harbor the government asked them to build tanks, and then airplanes. They did it with enthusiasm and efficiency. The difference is that they had a qualified buyer: the government.

So here’s an idea. Let’s offer Detroit the $25 billion. For that price tag, we’ll expect the factories to replace the entire federal fleet — tanks, trucks, postal vans, limousines, Forest Service jeeps — with flex-fuel plug-in hybrid electric vehicles. Last year, the feds operated some 642,000 vehicles. Subtract the 8,800 Abrams battle tanks, which would soak up the whole budget by themselves, and add a few hundred thousand vehicles for state and municipal fleets to round the production up to 1 million vehicles.  So $25 billion would replace the whole fleet for an average of $25,000 per. Not a bad wholesale price, especially when you figure in the fuel savings and then balance the cost of a Forest Service fire truck against a cheap sedan. A big chunk of the cost could be covered by selling off the old fleet to equatorial countries where palm-tree mechanics will happily convert them all to run on sugar ethanol.

The flex-fuel requirement is important. It means that a gasoline engine would also accept ethanol or methanol, a diesel would also accept jet fuel or vegetable oil, and a natural gas engine would also run on propane or methane. It means that every fuel source has market competition, and a fleet operator can look further afield for low bids.

A federal flex-fuel plug-in hybrid-electric vehicle is a FFFPHEV.  I can’t wait to hear a senator pronounce that. And a five-year replacement plan for flex-fuel plug-in hybrid-electric vehicle replacement plan is a FYRPFFFPHEV.

>>Axxis of Oil
November 17, 2008, 5:03 pm
Filed under: Climate science, Fossil fuel

Sunday’s New York Times ran a solid look at Exxon, the world’s largest corporation. Business writer Jad Mouad reports that company is dedicated to squeezing every drop of profit out of every barrel of oil it can find over the next half century.

Mouad says:

During the tenure of Lee R. Raymond, who ran the company from 1993 to 2005, Exxon became the lightning rod in the debate about climate change. Throughout the 1990s, the company was vilified by environmental groups and scientists for questioning the impact of human activities — especially the use of fossil fuels — on global warming.

In fact, according the Union of Concerned Scientists, Exxon spent about $16 million on a misinformation campaign meant to delay carbon-mitigation measures (NREL’s Chuck Kutscher discusses the UCS report in the upcoming January/February issue of SOLAR TODAY). Now, Mouad says,

Gingerly, over the last three years, Exxon has moved away from its extreme position. It stopped financing climate skeptics this year, and has sought to soften its image with a $100 million advertising campaign featuring real company executives, scientists and managers. One of the ads said the company aimed to provide energy “with dramatically lower CO2 emissions.”

That’s a smokescreen. The current chairman, Rex Tillerson, is even more rigidly devoted to fossil fuel strategies. Unlike some of its competitors, Exxon has made no moves to diversify into non-fossil energy sources. Last summer, Tillerson beat back an attempt by rebellious shareholders — including members of the founding Rockefeller family — to take a broader view of the company’s future.



>>Renewable industries offer to-do list for incoming politicos
November 13, 2008, 4:11 pm
Filed under: Policy

Renewable industry execs are putting together wish-lists for quick government action after Democrats take over Congress and the White House in January.

According to Matt Nauman, writing in the San Jose Mercury-News, SunPower VP Julie Blunden has asked Barack Obama to put PV panels on the White House roof. The symbolism would be strong for solar advocates, who recall the day Ronald Reagan had Jimmie Carter’s solar array torn down.

And Washington-based advocacy organizations released the following joint statement:

The leaders of the American Wind Energy Association, Geothermal Energy Association, National Hydropower Association and Solar Energy Industries Association today released the following statement:

The fast-growing renewable energy sector is poised to help lead the U.S. economic recovery with millions of new jobs and billions of private investment dollars. However, the new Administration and Congress need to take action to ensure that the renewable industries’ growth continues, given the current economic realities.

President-elect Obama has made a commitment to key policies that will spur substantial growth in America’s clean renewable energy industries and create millions of new jobs.  Building upon these key policies, the renewable energy industries’ top priorities for the Obama Administration and the 111th Congress include:

  • Immediate Action: Adjust renewable energy tax credit policies so incentives work as intended given current economic conditions.

  • 111th Congress:
  • Adopt a national renewable electricity (portfolio) standard to ensure that at least 10 percent of electricity consumed in the U.S. is derived from renewable energy sources by 2012, and at least 25 percent by 2025;
  • Approve a minimum five-year extension of the federal renewable energy production tax credit (PTC) and additional funding for the Clean Renewable Energy Bonds (CREBs) program;
  • Issue an Executive Order expanding federal procurement of renewable energy generation to meet the government’s substantial energy supply needs;
  • Launch a major initiative to support investment in our nation’s interstate electrical grid infrastructure and smart-grid technology to deliver green energy from areas with renewable resources to population centers and to support distributed power generation;
  • Invest $30 billion in 2009 for financing options that support new project development and installations for all renewable energy technologies as part of the Administration’s commitment to investment of $150 billion over the next ten years in clean energy technologies;
  • Adopt a cap-and-trade regime to reduce greenhouse gas emissions that rewards production of clean renewable energy.

If the Administration and Congress can quickly implement these policies, renewable energy growth will help turn around the economic decline while at the same time addressing some of our most pressing national security and environmental problems.  Expansion of renewable energy production will mean billions of dollars in economic growth, millions of new jobs, enhanced energy security as we increase domestic energy production, and critically important progress in reducing greenhouse gas emissions.

>>Gore’s 5-point plan
November 10, 2008, 5:04 am
Filed under: Policy

Al Gore ran an op-ed in The New York Times on Sunday, outlining a 5-point energy-economy recovery plan for the new Obama administration.  It’s worth a read.

Briefly, Gore calls for:

1. Large-scale investment in Southwestern utility-scale solar plants, Great Plains windfarms and Mountain State geothermal plants.

2. Deployment of a unified national smart grid, using high-voltage underground lines.

3. Help for the auto industry — start-ups as well as the Big Three — to convert quickly to production of PHEVs.

4. A program to retrofit building with energy-efficient insulation and windows, coupled with help for mortgage holders.

5. A price on carbon emissions.

Here in Boulder County, we’re doing our share. We passed our Proposition 1A, putting the county into the business of loaning money for rooftop solar installations.

And Yamavolt, the electric road racer, is tidied up and back on commuting duty. Looks good enough now that I think I’ll start showing it off at renewable energy functions.
