Carmakers are falling over themselves to announce full-electric, hybrid, and alternative-fuel vehicles at this year’s Detroit auto show. Chevrolet announced a concept for a mid-range fully electric car, the 200-mile-range Bolt, that might cost around $37,500 before tax credits in its 2017 lineup. The Bolt, designed by an Australian subsidiary of GM, will use a battery under development by LG that has a less block-like design than conventional battery packs and could offer carmakers more design flexibility.
The only current widely distributed electric car in that price range, the 84-mile range Nissan Leaf, will see “a lot of enhancements,” in time to compete with the Bolt, says Nissan-Renault CEO Carlos Ghosn. Other companies, such as BMW and Audi, are also commercializing full EVs, but the Chevrolet announcement is a sign that mainstream American carmakers are now stepping into the fray.

Gardeners making their rounds through Barcelona’s Parc del Centre del Poblenou these days are as likely to carry tablets as trowels. The city recently moved 178 of its irrigation points to an Internet-controlled system. While it is handy to manage watering at the keyboard instead of turning a knob on a pipe, much of the advantage is in the data that the new system sends back to a central software system the city has built.

Men died in gun battles over the installation of windmills in the state of Oaxaca, Mexico, three years ago. Opponents argued that energy companies misled them and that community leaders rented out collective lands without consulting everyone they should have. Today, protests continue, but the growth of wind farms and other renewables seems assured: Mexico boasts almost 2 gigawatts of installed wind power capacity and plans to install perhaps another 12 GW by 2022. All that clean energy is a big change for this country, which is the world’s ninth-biggest oil producer and perhaps the 11th-biggest emitter of carbon dioxide. Continue reading
