Warren Buffett’s $26billion renewables bet set to pay off

Warren Buffett’s $26 billion bet on western U.S. power plants, transmission lines and wind farms is poised to pay off. Buffett’s Berkshire Hathaway Inc., with the help of California’s grid operator, is moving to unite the holdings under a single market capable of dispatching power across seven states every five minutes. The system, designed to handle sudden swings in supply and demand, would revolutionise the markets from Oregon to Nevada, where 38 transmission operators manually balance their territories on an hourly basis. The move would be a game-changer for the renewables that Berkshire Hathaway Energy Co. has accumulated over the past decade, including two of the world’s largest solar farms, and for other clean-power producers, according to those who trade in the region’s markets. Berkshire’s plants stand to run for longer periods of time, and its NV Energy Inc. and PacifiCorp utilities will save as much as $63.9million annually by 2017, Energy and Environmental Economics Inc. reports show.

Solar farmers in Japan to harvest energy with crops

Japan’s campaign to boost renewable power supplies since the Fukushima nuclear disaster is producing some unlikely winners: vegetable farmers. Makoto Takazawa and his father Yukio earned 1.7 million yen ($16,700) last fiscal year selling electricity from solar panels that hang in a giant canopy above their farm east of Tokyo. The cash was almost nine times more than they made from the crops growing in the soil below. Harvesting dual incomes from sunlight was a godsend to the Takazawas. They’re among the majority of Japanese farmers who depend on a combination of outside work, pension payments and government subsidies to make a living. The easing of land-use rules and mandates for utilities including Tokyo Electric Power Co. to buy clean energy at premium prices is poised to fuel the spread of panels to more farms. “I was racking my brain to figure out what to do on this land that I’ll take over from my father one day, because growing rice and vegetables doesn’t bring in much money,” Takazawa said. “Then I heard about solar sharing for farmland.”
