China is facing pollution challenges today similar to what Los Angeles faced during the 1980s, a problem that energy efficiency helped mitigate. In China, combining cleaner heating fuels with better-insulated buildings is one concrete measure that would support cleaner skies in northern China and beyond, Stranger writes.
Shell has not decided whether it will proceed with Arctic exploration operations next year, Cunningham writes, but the oil major wants to keep its options open. Shell’s Arctic campaign, closely watched by the oil industry around the world, has thus far been tormented by setbacks and controversy.
Major companies more than ever before are driving the transition to renewable energy, but that effort is not without hurdles. Seif and Baker offer lessons learned from overcoming the challenges of making big business go green.
Pop and rock music boosted the efficiency of solar cells used to produce electricity by 40 percent, according to a study by scientists in London. Rock on, solar power.
Tesla Motors (TSLA) had avoided major battery complications until this fall, when three Model S cars crashed and their batteries caught fire.

Fuel cells were left by the wayside as solar power and wind power grew in popularity. But now it seems as though fuel cells are beginning to establish themselves in niches that show promise for the future, Kennedy writes.
Carbon dioxide pollution levels in Earth's atmosphere hit a record high in 2012, according a UN report released Wednesday. The concentration of carbon dioxide, a primary contributor to global warming, is far beyond the level some scientists and environmental groups say is the upper limit for a safe level.
From Virginia to Colorado to Washington, voters on election day 2013 threw their weight behind politicians and policies that limited the use of coal, oil, or natural gas. Bans on fracking, coal exports, and tar sands were on the ballot in a handful of states, and in most cases, the election day 2013 results did not favor fossil fuels.

An intelligent streetlight system, designed by Dutch Delft University of Technology, uses motion sensing technology that automatically dim streetlights when no pedestrians or vehicles are in the vicinity, Kennedy writes, and the idea is ready to go commercial.
India launched its first spacecraft to Mars Tuesday at a price tag of $72 million. It takes less fuel to propel India's Mars orbiter 485 million miles to the Red Planet than you think.
A new generation of 'smart' thermostats leverage cheap sensors, data analytics, and other bells and whistles of the IT world to take the guesswork out of programming your thermostat. It's an emerging field that is expected to grow as users demand more from their everyday devices.
With the British shale story in its infancy, a new report downplays the risk of hydraulic fracturing, or fracking, leading to groundwater contamination. Will Britain follow in the US footsteps towards a shale gas boom?
Residents of four Colorado towns will vote on fracking bans Tuesday. Oil and gas production is growing in the western states, and what happens in Colorado is being closely watched in other shale-rich states.
