California seeks solutions to higher energy costs

Amid a shifting landscape of growing consumer choices and increasingly exacting emissions regulations, state utilities and regulators have pressed ahead with a variety of initiatives designed to prevent energy shortages, consumer rebellions or a perfect storm of the two. 

Losing customers

Part of the challenge to the status quo has been posed by so-called community choice aggregations, or CCAs – local power agencies that more municipalities have embraced or considered switching to, away from legacy power utility companies. PG&E and other established players have begun to worry that too many switchers could leave remaining customers saddled with costs they can’t or won’t bear, leading to a potential death spiral for the big utilities.

“The state is ambitiously pursuing a fundamental transformation of the electric system to achieve historic greenhouse-gas reduction goals,” PG&E wrote to the California Public Utilities Commission in conjunction with two other leading companies, asking in effect for new rules that would prevent a rush to the exits, according to the San Jose Mercury News. “At the same time, the move toward customer choice through community choice aggregation, as well as other retail choice options, is accelerating.” 

Heightening the sense of urgency around appeasing customers as the hot summer months approach, PG&E suffered a frustrating mass outage event in San Francisco last Friday. “The power failure affected almost 90,000 Pacific Gas and Electric Co. business and residential customers, leaving Union Square, the Financial District, the outskirts of Chinatown and several other neighborhoods without electricity just after 9 a.m.,” as the San Francisco Chronicle reported

Tire pressure

Seeking to amp up energy supplies without running afoul of Sacramento’s tightening environmental restrictions, state officials have meanwhile focused renewed attention around an unprecedented technology that would harness the weight of tires in motion to produce electricity. They agreed, the Chronicle reported separately, “to fund an initiative to generate electrical power from traffic, a plan that involves harnessing road vibrations with the intent of turning the automobile, like the sun and wind, into a viable source of renewable energy.”

“The technology is peculiar but proven. Devices that convert mechanical force into electricity are used in watches and lighters and are being tested for power generation on sidewalks and runways. A San Francisco nightclub has even leveraged the pulses of a dance floor to power its lights and music,” the paper added. “Gravely helped draft the proposal approved [April 12] by the Energy Commission’s governing board, which will direct $2.3 million to two independent road projects designed to test the viability of scaling up piezoelectricity. ‘Piezo’ is Greek for ‘squeeze’ or ‘press’ and refers to using pressure to create power.”

The several-million-dollar budget will be split between “a 200-foot stretch of pavement on the UC-Merced campus” and “a half-mile of highway to potentially harvest enough power for 5,000 homes,” Jalopnik observed, with the latter effort to be spearheaded by the Pyro-E company. To capture the energy, the lengths of road “will be filled with tiny piezo arrays stacked ‘like quarters’ in the road surface,” the site noted. “Some estimates suggest that as little as 400 cars per hour would be needed to make the system economically viable.”

Uncertain reach

Skeptics, however, have questioned the real-world impact of the technology for years. “If the experiment proves out, California state officials say the system would be expanded to other roads. By recovering energy that would have gone to waste, such systems count as renewable energy sources under the state’s green-energy policy,” IEEE Spectrum allowed. “The problem is that nothing, not even waste energy, comes for free. Installing generating devices and keeping them running would add to the costs of road maintenance. And engineers might be tempted to design the roads to vibrate just a little more than otherwise so as to increase the efficiency of the harvesting – thus causing the roads to crumble even faster. The true economic break-even point would be hard to estimate, and it might be all too easy for piezoelectric proponents to convince themselves that they’re getting a free lunch when they aren’t.”

    Someone needs to do a bit of math and be reminded of the conservation of energy laws. It would only takes minutes to realize this is a dead end.

    Well Idaho got swindled out of $6.4million to test a solar road that produced enough energy all day to power a microwave. I put this up there with perpetual motion and equipping cows with tubes into their stomachs and capturing methane in backpacks strapped onto them. Oh wait the latter was actually suggested at a CARB meeting. We’re doomed

    California’s answer to high energy prices is to raise them ever higher.
    The D-rat donors including the coastal elites, greenies,tech tycoons, and Hollywood trash can afford to pay whatever price the state tyrannical dictators want to charge.
    The rest of you…the ‘little people, middle class, working poor, etc you can leave if you don’t like it. Most of you probably voted for Trump anyway.
    As long as we have enough illegals, government cheese eaters, and tax grazers who will work for cash to clean our houses, mow our lawns and nanny our children we’ll be OK.
    High energy costs drive out manufacturing jobs and the riff-raff who work for them. Get out—now!

    Even wasting one momment considering this crazy ass technology is too much! This behavior is so typical of how Democrat politicians, who never have business experience, always waste tax money when they gain a majority in any legislative arena. As a group, they are dumb as stumps. If these types of actions continue much longer it will surely warrant formal consideration of splitting California into at least one more state.

    Despite our isolation as an energy island with the Sierra Mountains on one side and the Pacific Ocean on the other side, there are no pipelines “into” the state from the rest of the country, California’s energy island has grown to be the sixth largest economy in the world, and it’s driven by fossil fuels. Yet, our elected officials and appointed CARB folks are not aware that fossil fuels are the economic powerhouse of California. http://www.ocregister.com/2017/05/05/fossil-fuels-are-the-economic-powerhouse-of-california/

      I was at a local solar manufacturer back in 2012. The engineer and I were talking and I said how impressed I was with this technology.

      Well, the engineer says “we can build factories for 20 years, we can build solar plants for 20 more years and it will still only be 5% of what the world needs. We still need hydro-electric, we still need petroleum and coal and we still need nuclear.”

      Facts are such a wake up, aren’t they?

      Cheers Mr Stein.

    This idea ranks right up there with the bullet train from nowhere to nowhere, regulating cow emissions and all the rest of the stupidity coming those Ner do Wells in Sacramento who sit in their ivory towers and receive outlandish salaries and exempt themselves from their own stupitity!
