Time to toot my horn. The Society of Environmental Journalists has honoured my work in their 2015 Awards for Reporting on the Environment. I took first place in Outstanding Beat Reporting, Large Market, for “History, Technology, Politics and Impact of Solar Power” — a series of articles published in MIT Technology Review and IEEE Spectrum magazines:
In their comments accompanying the award the judges recognize the difficult balance between depth, accuracy, and accessibility that keeps me pounding away at the keys and fighting to get it right by the deadlines:
In his Large Market Beat Coverage of solar power, journalist Peter Fairley goes wherever he needs to go to best illustrate his stories. He takes us to the Atsumi Peninsula in Japan, where post-Fukushima renewable energy is needed to make up for the loss of the country’s nuclear reactors. He acquaints readers with the island of Kauai, Hawaii, where they’re tackling solar power’s biggest challenge—its intermittent nature. And we’re shown around California’s Carrizo Plain, where the world’s largest photovoltaic power plant has the potential to generate more energy than the grid demands. This is satisfying journalism. With anecdotes, scenes and knowledgeable sources, Fairley keeps us interested as we’re reading, and he leaves us feeling fulfilled when we’re finished. The stories are in-depth but readable, technical but understandable. It’s refreshingly clear and compelling journalism around a topic that easily could be either too esoteric or too superficial.
My heartfelt thanks go out to all of you who have encouraged me by following and sharing my reporting, and for your belief in my work to empower intelligent and informed action towards a more sustainable and safer world.

Distributed energy solutions, such as rooftop solar, should be the electrification solution for the 1.1 billion people who are not plugged into a national power grid, not just a stopgap measure. That is the message from a new global industry group, Power for All, launched in New York City this week amidst the latest gathering of the United Nations’ universal energy access program.
Power For All brings together businesses and not-for-profit organizations that distribute off-grid solutions, including solar-LED lights and home power systems. Founding members include San Francisco-based d.light; Arusha, Tanzania-based Off Grid Electric; and London-based NGO SolarAid—owner of solar-LED light global market leader SunnyMoney, which sold 650,000 lights last year.
Their message is that bottom-up distributed energy solutions should be thepreferred solution for assuring universal access to electricity because they are faster, cleaner, and cheaper than extending power grids to rugged or sparsely-populated regions.
Hawaii’s legislature voted yesterday to stake the state’s future on renewable energy. According to House Bill 623, the archipelago’s power grids must deliver 100 percent renewable electricity by the end of 2045. If the compromise bill is signed by the governor as expected, Hawaii will become the first U.S. state to set a date for the total decarbonization of its power supply.
That last jump could be difficult, says Peter Crouch, a power grid simulation expert and dean of engineering at the University of Hawaii’s flagship Manoa campus. “Today I don’t know whether we can do it,” he says. Continue reading →
Nuclear power plants’ reactor pressure vessels (RPVs)—the massive steel jars that hold a nuclear plant’s fissioning fuel—face incessant abuse from their radioactive contents. And they must be built with extra toughness to withstand pressure and temperature swings in the event of a loss-of-cooling accident like the one that occurred at Fukushima in 2011. As the triple meltdowns at Fukushima Daiichi showed, the next layer of defense against a nuclear release—the so-called containment vessels—can not be counted on to actually contain molten nuclear fuel that breaches the RPV.
Nuclear safety authorities have recently discovered weaknesses in several RPVs, and their contrasting responses suggest that the ultimate lessons from Fukushima are still sinking into international nuclear power culture—especially in the United States, where the Nuclear Regulatory Commission (NRC) is resisting calls to mandate tougher inspection of RPVs.

Adding energy storage to sites with rooftop solar power generation offers a range of potential benefits. A battery can help smooth out solar’s inherently variable supply of power to the local grid, and even keep buildings powered during blackouts. Consequently, power-conversion innovators are developing a host of new products designed to reduce the cost and improve the efficiency of integrated solar-storage systems.
According to Vic Shao, CEO for the Santa Clara, California-based energy storage startup Green Charge Networks, tightly integrating storage with photovoltaics in some key states—including Hawaii and California—runs afoul of the “net metering” rules by which PV owners earn lucrative retail rates for the surplus power they feed to the grid. Adding storage can disqualify solar systems for net metering, in which utilities can pay their owners wholesale power rates that are several times lower than retail. “That is obviously a pretty big problem for anybody considering solar. That could kill a lot of projects,” says Shao. Continue reading →
Solar forecast for March 20 from Energy-Charts.de, with prior days’ solar output
Weather forecasts calling for bright sun today across Europe drove up tensions in advance of the partial solar eclipse that blocked the sun’s rays and plunged much of the continent into a brief period of darkness this morning. Grid operators were bracing for record swings in solar power generation because of the celestial phenomenon. Some power distributors in Germany had warned of fluctuations in frequency, notifying customers and suggesting that they shut down sensitive equipment.
In the end, while clear weather made for some excellent eclipse viewing, the electrical story ultimately felt more like Monty Python’s radio coverage of the 1972 eclipse. As if audio coverage of a quintessentially visual event isn’t absurd enough, the Pythons closed their fictitious report in the ultimate anticlimax, as a sudden rainstorm swept in to spoil the solar spectacle. Europe’s interconnected power grid brought about an equally anticlimactic ending today by delivering rock-solid stability throughout the 2.5-hour eclipse. Continue reading →
“It’s a very, very big challenge for the transmission system operators in Europe,” says Enrico Maria Carlini, Head of Electric System Engineering for National Dispatching at Rome-based Italian transmission system operator Terna.
The Brussels-based European Network for Transmission System Operators for Electricity (ENTSO-E) judges in an eclipse impact analysis released last month that it poses a, “serious challenge to the regulating capability of the interconnected power system.”
While an eclipse markedly reduced solar generation in western North America last October according to energy tracking firm Opower, Europe’s far greater levels of solar power make for bigger stakes. ENTSO-E projects that the moon’s jaunt across the sun’s path next Friday could slash more than 30 gigawatts (GW) of solar generation in Continental Europe over one hour if clouds are scarce and solar generation is high. That’s the equivalent of turning off 30 big coal or nuclear power stations. Continue reading →
