Note: This is a revision of the same post from last week, with an updated time-of-use pricing plan from Los Angeles. What if electricity cost more when the sun was shining? Many utilities are using new electronic “smart meters” to adjust the price of electricity as often as every 15 minutes, to reflect supply and… Continue reading

Solar grid parity is considered the tipping point for solar power, when installing solar power will cost less than buying electricity from the grid. It’s also a tipping point in the electricity system, when millions of Americans can choose energy production and self-reliance over dependence on their electric utility. But this simple concept conceals a… Continue reading
Conducted by market research institute Forsa on behalf of municipal utilities in Germany, the survey found that 61 percent of Germans are willing to pay more for their power if the extra cost helps ramp up the share of renewables. Public acceptance even extends to acceptance of wind turbines “in my backyard”; 54 percent of those surveyed said they would find it “good” or “very good” if a wind turbine were set up nearby.
That’s the German feed-in tariff at work…
Update 1/12/12: I created a new post to reflect the current time-of-use pricing plan for Los Angeles Update 1/10/12: Fixed a missing pie chart and corrected a miscalculation caught by a reader What if electricity cost more when the sun was shining? Many utilities are using new electronic “smart meters” to adjust the price of… Continue reading
Yesterday New York Times reporter Matt Wald had a piece on the role of energy storage in supporting the expansion of renewable energy. However, his specific focus on solar thermal power generation overlooks the potentially high costs of relying on solar thermal power as well as the potential for distributed “storehousing” of renewable energy. Solar… Continue reading
In this Nov. 20 interview with Baruch on his WKBM Paradigms program, we talked about: The coming decentralization of the electricity system The folly of a building inherently decentralized technology (wind and solar) in a centralized fashion The benefits for local ownership of a decentralized system How limited economies of scale for solar and wind… Continue reading
In this short interview on KGNU’s science show – How on Earth– with Tom McKinnon, we talk about: the problems presented for local ownership of energy resources when federal incentives use the tax code, the trouble for clean energy when it’s reliant on Wall Street, how Boulder, CO, may accomplish something remarkable with its vote… Continue reading
Where does solar grid parity strike first? How fast does it spread? Click “animate” on the map below to see which major metropolitan areas can beat grid prices with local solar first, and how quickly unsubsidized solar could take over America’s major metropolitan areas.
In January, I plotted the size of state solar markets against their average installed cost and found surprisingly little correlation. When Lawrence Berkeley Labs put out their 2011 version of Tracking the Sun (IV), it was possible to update the chart, which I did in two stages. The first chart simply overlays the 2010 average… Continue reading
One doesn’t need 540 MW of reserve to back up 540 MW of small-scale distributed generation, but one does need it to back up a single critical 540 MW unit.
