  • Field test documents big consumer savings

    A Northwest field test of smart-grid technologies has documented tremendous potential to run a grid that delivers power far more economically by controlling peak demand.

    The Pacific Northwest GridWise Demonstration Project has just announced the results of their year-long test, which included two pieces:

    • On the Olympic Peninsula of Washington, 112 homes, three onsite generation units and municipal water pumps were equipped with automated systems that allowed them to adjust grid power demand in response to price signals.
    • Appliances embedded with microchips capable of automatically responding to grid power fluctuations were placed at 150 homes in Washington and Oregon.

    The aim of the Pacific Northwest National Laboratory-managed project was to document the ability of automated control systems to cut usage of the most costly power. Reducing demand can eliminate the need for peak power plants and delivery systems used only a relatively few hours of the year. Among the study's findings:

    • Average power bill savings among customers who participated in the Olympic test were 10 percent, and peak load reductions 15 percent.
    • Power use reductions plus distributed generation reduced peak power distribution loads 50 percent for days at a time.
    • These technologies have potential to lower peak power prices plus save $70 billion over 20 years by avoiding the need to build peaking plants and wires.
    • If all appropriate appliances were equipped with the intelligence to respond to grid conditions, 20 percent of U.S. power demand could be adjusted, tremendously reducing the level of blackouts and brownouts.

  • Hybrid emissions: Facts and numbers

    Having laid out my views in part I, let me turn to the actual data regarding hybrids -- both from an environmental and economic perspective.

    How do carbon emissions per mile driven compare for various cars? The Volt is expected to be "less than $30,000" with a 1.0L engine. Compare this to the Corolla, with a 1.8Lengine (peak hp of 126; 31 mpg) and a price of $14,400. It's worth noting that this is in the optimistic, no-gasoline-use scenario for the Volt, computed below along with carbon emissions for the Volt running on cellulosic ethanol and gasoline, and emissions for comparable-sized ICE cars. Questions on the Volt's actual usage patterns remain: how many people will recharge everyday? What percentage of total miles will be on the grid, and what percentage on gasoline?

  • E.U. says it will be mindful of sustainability in boosting biofuels

    Realizing that biofuel production can have negative social and environmental consequences, the European Commission says it will propose “strict conditions that biofuels used in the European market are produced in a sustainable way” instead of barreling ahead willy-nilly (because really, that would be crazy). The commission will announce specific climate-change mitigation plans later this month; […]

  • Antarctica ice melt more widespread and faster than thought, says study

    Antarctica holds about 90 percent of the Earth’s ice, so it’s a bit problematic that the continent seems to be melting faster than expected. Not only is large-scale ice loss more widespread than thought, but the rate of meltiness has accelerated over the last decade, says a study in the journal Nature Geoscience. The West […]

  • Cape Wind project given preliminary environmental approval

    Seems it was only October that the controversial Cape Wind project in Nantucket Sound was dealt a setback. Now here it is January, and the wind farm that NIMBYs love to hate is inching forward, having been given preliminary environmental approval from the Minerals Management Service. After a public comment period, the final fate of […]

  • Draft EIS for Nantucket Sound wind project is positive

    The Mineral Management Service's Draft Environmental Impact Statement on the Cape Wind project is just out, and so far looks very positive, finding no environmental reasons to halt the project as it is envisioned.

  • Prius: Green or greenwash?

    I have been accused of dissing hybrids. I was mostly discussing Prius-type parallel hybrids and all the support they get, when one can get the same carbon reduction by buying a cheaper, similar-sized and -featured car and buying $10 worth of carbon credits. I was objecting to greenwashing (powered by a large marketing machine) that suggests hybrids can solve our problems.

    Corn ethanol, which has been heavily maligned in the mainstream media, reduces carbon emissions (on a per-mile-driven basis) by almost the same amount as today's typical hybrid. Despite the similar environmental profiles, one is a media darling and the other is demonized, despite its more competitive economics.

    My main complaint has been the lack of critical analysis in this space. Corn ethanol (which I don't believe is a long term solution) has been framed by the oil companies' marketing machine, farm policy critics, and impractical environmentalists (though the NRDC and Sierra Club support corn ethanol's transition role as I do, subject to certain constraints). The Prius and hybrids have been positioned by Toyota's marketing machine. The public is gullible.

    I am open and hopeful, especially longer term, on serial plug-in hybrids (a point I'll address in Part III). Price still remains a major issue. Even for serial hybrids, the ability to keep cost, or at least monthly payments, close to that of a regular ICE (internal combustion engine) car is unclear. Maybe another blogger with knowledge of practical automotive costs can detail the likely trajectory of serial hybrid costs (say, with a typical 40-mile "battery range"), as this remains the critical question.

    The Prius is the corn ethanol of hybrid cars, and we should recognize that. It has increased investment in battery development, but beyond that it is no different than Gucci bags, a branding luxury for a few who want the "cool eco" branding (70%+ of Prius buyers make more than $100k per year).

    In this series, I will try to lay out my views on hybrids as a whole -- what I believe hybrids are good for and what they are not. (My paper on Biofuels Pathways (PDF) delves into the details.)

  • Coal is not cheap, part XVXIV

    Clean coal plants are dying on the drawing board. Why? Because … stop me if you’ve heard this one … coal can be cheap or clean, but not both.

  • There is a silver-bullet solution to global warming

    The dialogue between this country's youth and key decision-makers during the important Focus the Nation (FTN) event on January 31st has the potential to become diluted and confused. If it does, another opportunity to move a segment of the country towards seriously addressing climate change will have been wasted.

    Shotgun Approach Falls Short

    Although every personal effort at reducing energy use and greenhouse-gas emissions is laudable and helps change the way we think about global warming, taking the shotgun approach to emissions reductions is simply not enough. Time is extremely short, and we must act immediately and boldly if we are to avert a climate crisis.

    The Silver Bullet

    Contrary to what many are saying, there is a "silver bullet" solution to global warming, and it is time we, as a nation, faced up to it.

  • WTFx3

    Leader of group fighting Cape Wind project makes $203,000 last year (WTF?), quits this year to go work in the wind industry (WTF?), and hands over leadership of the group to a former coal executive (WTF?).
