Rooftop solar & decentralized generation can save California

Rooftops may not be the final frontier, but they do provide ample fields for cultivating solar panels.

So says Al Weinrub, who has penned "Community Power: Decentralized Renewable Energy in California." Weinrub is a member of the Sierra Club California Energy-Climate Committee and serves on the Steering Committee of the Bay Area’s Local Clean Energy Alliance. He said he relied extensively on work from both.

"Decentralized generation means that local residences, businesses, and communities become electric power producers," he writes. "Businesses with large rooftops or parking lots can become small power companies that feed electricity into the grid."

The beauty is that these buildings are already connected to the electrical grid and have an existing footprint, benefits that a remote solar installation doesn't always have. Industrial solar on empty land requires extensive permitting, studies and review of environmental impact, especially if its federal. Those panels definitely can change a picturesque landscape.

3 developments accelerate clean energy evolution

When I was 17, I discovered how fast my step-father's then almost-new 1976 SR5 Celica fastback would go.

105 mph.

Urging me on was a not-so-shabby Chevelle. It passed me heading out the deserted Glenn Highway near Mirror Lake going about 90. I blew past it at what I discovered to be top speed, catching a little air on the rolling frost heaves outside Anchorage.

I'm getting that same sense of wide-open acceleration now, watching developments in clean energy. Technologies appear to be testing just how fast they can move forward.

Solar and LED lighting threaten to go mainstream with price reductions. But other technologies also show exceptional promise.

1. Passive House. A house at the Cleveland Museum of Natural History designed with no furnace -- honest -- has been completed and is already catching attention. The residence, which uses "passive house" design and technology, cuts its greenhouse gas footprint and utility costs to the quick. SmartHome Cleveland received a national write-up from Renee Schoof of McClatchy Newspapers.

"Because the house is so well insulated, it can hold heat from sunshine, body heat, lights and appliances," she wrote.

California breaks free from from fossil fuels, gradually

California is breaking free of its fossil-fuel addiction.

That's according to Next 10's "2012 California Green Innovation Index." The phrasing was "gradually transitioning."

The report, which looks at the previous year's data, says the Sunshine State surpassed 1,000 megawatts of solar energy capacity, attracted $3.5 billion in cleantech investment in 2011 and accrued 910 green technology patents for a first-in-the-nation performance.

Findings in the 75-page report sound positively radiant, especially in light of news that subsidies like those provided by the American Recovery and Reinvestment Act of 2009 are disappearing, economic and international pressures continue and many renewable energy companies are struggling to survive.

California is unique

But F. Noel Perry, Next 10 founder, offers no apologies. In his prelude, he says, "California’s ability to foster and develop new ideas, markets and technology is unique." He says the purpose of the Index "is to document the impacts of California’s efforts to transition to a low carbon economy in order to understand what works and what doesn’t in driving innovation."
