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.
The carbon bubble idea is an interesting hypothesis, Styles writes, but there are some flaws in the arguments Al Gore makes in its support. Carbon bubble or no, there's nothing wrong with investors wanting to track their carbon exposure, consider shadow carbon prices, or ensure they are properly diversified.

Recent pipeline spills in North Dakota have drawn attention to the nation's extensive oil and gas pipeline network. Pipeline capacity is short of what's needed to keep pace with oil production in the United States, Graeber writes, and the regulatory agencies to monitor safety aren't up to snuff.
Happy Halloween: Trick or treat? Solar or oil? Even Halloween jack-o'-lanterns have joined the energy debate. When the Department of Energy promoted clean energy and efficiency as pumpkin-carving suggestions, the US oil and gas lobby served up its own Halloween ideas.
