  • A brief primer on variable vs. fixed costs

    For those of us in the power industry, media discussions of the economics of power generation reveal an almost complete misunderstanding of how power is priced. Depending on our vested interests, we may find this either frustrating or beneficial -- but in all cases, it's false.

    Herewith I attempt to explain from whence the confusion arises -- and why it is so critical for the clean energy community to understand this math and its consequences ... and to more accurately articulate the economics of those options we prefer.

  • Low-carbon energy solutions in India may depend on Tata

    Amid analysis of the G8's latest climate pronouncement, the announcement of India's first national climate action plan received less attention than it otherwise might have. Even in the Indian media, the plan was also overshadowed by the release of a McKinsey & Co. report that projects massive power demand growth in the country -- 100 gigawatts more demand in the next 10 years than previously estimated. Yet the very same day, the government's Investment Commission called the "Ultra-Mega" coal plants that are central to India's strategy to meet that demand a "main reason for persistent capacity shortfalls."

    As reported by India's Financial Express, the climate change "National Action Plan" consists of a laundry list of programs to be initiated -- or more likely, repackaged -- on solar power, energy efficiency, agriculture, and a few others. Based on previous performance in the power sector, agriculture seems to be the most promising of those programs (especially considering the Indian government's success in raising productivity during the Green Revolution). One can hope India will have the same success, and be able to utilize the same distribution mechanisms, in efforts to create seed varieties adaptable to drier climatic conditions.

    If McKinsey is right, India's demand will soar to 315-335 GW by 2017, from 120 GW installed capacity today. To supply that demand reliably would require over 415 GW of installed capacity -- that's triple what the creaky Indian power sector produces now. And about 10 times what even the dozen planned Ultra-Mega plants could hope to supply.

  • Aviation industry is into greening, to an extent

    The aviation industry talked up greenness Wednesday at the world’s biggest air show in Farnborough, England. At a sustainability summit, Giovanni Bisignani of the International Air Transport Association called climate change an “emergency situation” and said airlines are the best suited to address it: “No other industry is as responsible, united, and ambitious.” Indeed, the […]

  • Wal-Mart, mining companies team up to trace path of jewelry supply chain

    Retail giant Wal-Mart is joining with Conservation International as well as mining companies Rio Tinto and Newmont Mining to launch a pilot project that lets customers trace the path of their jewelry from mine to mega-store. Marketed as Wal-Mart’s “Love, Earth” brand jewelry, the items stand out from others in that once they’re purchased, customers […]

  • New business coalition wants cheaper energy, stat

    A group of businesses has kicked off a new campaign with the goal of making energy cheaper by whatever means possible. The new Coalition for Affordable American Energy — not to be confused with, ahem, the existing Coalition for Clean Affordable Energy or Coalition for Affordable and Reliable Energy — is backed by various business […]

  • Some school fundraisers start hawking greener products

    Some school and nonprofit fundraisers recently have turned to greener options to generate needed cash. Instead of sending youngsters out into the community to hawk items of questionable greenness like candy, magazines, and virgin-forest wrapping paper, some schools have instead turned to greener wares such as fair-trade coffee, metal water bottles, hand-made soaps, and recycled-content […]

  • Nuke-power company Exelon announces big emissions cuts by 2020

    Nuclear-power company Exelon today launched a program it says will reduce greenhouse-gas emissions by over 16 million tons a year by 2020 — more than the company’s current total annual emissions. The company’s plan calls for buying renewable-energy credits to offset some of its emissions, generating a small amount of electricity from alternative sources such […]

  • Rental-car companies struggling to meet demand for smaller cars

    Consumer demand for smaller cars is putting car-rental companies in a bit of a bind. Until recently, American automakers were glad to unload overstock to Hertz, Avis, and Thrifty at a discount, then guarantee a price to buy the cars back used. But with demand for hulking American cars dropping, Detroit has cut back production […]

  • Paychecks growing fatter for Big Oil execs

    Everyone is acutely aware that the price of oil is surging and gas prices break a new record almost daily. Less well-reported -- yet completely unsurprising -- is that the paychecks of Big Oil CEOs are also reaching new heights, according to a report by Equilar, as reported by MSN Money.

    Median S&P 500 CEO compensation: $9.9 million. Big Oil CEO pay range: $15-$21.7 million (!)

    Rex Tillerson, CEO of ExxonMobil, raked in an astonishing $21.7 million and is sitting on nearly $78 million of unvested stock options. (Though this is chump change compared to the obscene $500 million golden parachute his predecessor, Lee Raymond, received upon retirement. That is of course also the same amount ExxonMobil will have to pay in punitive damages for the ExxonValdez disaster, thanks to a recent wrongheaded Supreme Court decision.)

    David O'Reilly, CEO of Chevron, made $15.7 million and is sitting on $26.3 million in unvested options.

    James Mulva of ConocoPhillips made $15 million and has a whopping $234 million in options.

  • As the ground shifts under their feet, food giants experiment with new strategies

    When you smile, the food world smiles with you … maybe.

They’ve had access to cheap energy to ship food over globe-spanning distances and run giant food-processing plants; […]
