To solve the problem of inequality, the mayor of Bogotá, Colombia turned to better buses and more bike lanes, Guevara-Stone writes. Can urban development done right develop a more egalitarian and sustainable city?

The nuclear industry is lining up heavy hitters from past administrations to convince Congress and the public that nuclear power represents a solution to climate change. But safety fears post-Fukushima, along with concerns about high building costs and the lack of permanent storage for spent fuel rods, remain big hurdles.   

Americans across the country are weighing the benefits and downsides of increased domestic energy production, and the controversial new technologies that come with it. Increasingly, they're also debating who gets to decide when and where fracking happens, or if it takes place at all.

Tesla Motors chief executive Elon Musk confirmed the Model 3, a forthcoming electric car that will cost less than half its coveted Model S. Can a cheaper Tesla Motors model woo a broader public still wary of electric cars?

Inexpensive nanotubes – sheets of carbon rolled into pipes thinner than a human hair – may be the key to making hydrogen fuel cleaner and less expensive. A new study shows how nanotubes could bring clean energy technologies closer within reach.

With US energy production booming, Sen. Lisa Murkowski (R) of Alaska is leading the charge to overturn a decades-old ban on US crude oil exports. Murkowski met with the Obama administration this week to discuss oil condensate exports and the prospect of further loosening the oil export ban.

Google is teaming up with an environmental group to map methane leaks from natural gas pipelines in US cities. Methane contributes to global warming, and Google hopes its new maps will encourage utilities to patch and replace old pipelines.

Russian President Vladimir Putin has signed several energy deals in Latin America as he visits the region this week. Will it hurt the US's energy influence, or is Putin just focused on expanding Russia's economic relationships?

Beaver dams have so far prevented about 1 million gallons of fracking wastewater discovered spilled July 8 from a rural North Dakota pipeline from spreading too far. But, many North Dakota residents and experts are calling for more regulations and reliable measures.

European officials are using transatlantic trade talks to push for access to the US shale oil and gas boom, largely off-limits due to decades-old trade restrictions on US energy exports. Environmental groups and consumer advocates oppose lifting the ban on concerns it will raise domestic energy prices and contribute to climate change.  

US ratepayers will pay 3 percent more for electricity this year – the biggest increase since 2008, according to US government projections. The higher prices come after a harsh winter that strained the Northeast's grid and boosted natural gas demand.

The world has 53.3 years left to find an alternative to oil before current proved reserves run dry, according to BP. Of course, nations are finding new oil – meaning that number is rising – but new extraction methods are costly and can pose environmental threats.

Two companies are looking into shipping liquefied natural gas through the Arctic Ocean. What environmental and economic effects would an Arctic Ocean shipping route have?

Elon Musk, father of the Tesla electric car, honors the Tesla who revolutionized electric power transmission. His donation will help create a science center showcasing Nikola Tesla's many inventions.

President Obama's pledge to end US support for overseas coal projects is on the chopping block, as Congress debates the future of the US Export-Import Bank. A reversal of the coal ban would deal a blow to the administration's Climate Action Plan.

Researchers have developed a sponge-like silicon they say could be safely used to store energy in batteries. Using this silicon in smartphone batteries, for instance, could allow batteries to last 30 percent longer than traditional lithium-ion batteries. 

Ahead of next year's Paris climate talks, it's time for a new approach to climate change that supports making clean energy cheaper than fossil fuels without subsidies, writes Matthew Stepp of the Center for Clean Energy Innovation. The only way to do that is with more innovation. 

South Stream, a proposed pipeline to bring Russian natural gas to southeastern Europe, threatens to undermine Europe's solidarity forged during the Ukraine crisis. Some see the pipeline as a necessary alternate supply of gas while others say it will only give Russia more leverage over European energy.

'Rolling coal,' the practice of blowing thick, black plumes of smoke from tailpipes, is gaining traction as a protest against growing environmental regulation. Rolling coal drivers sometimes spend thousands of dollars modifying their vehicle.

Two-bladed wind turbines aren't new to the world. But, a Chinese company is building a six-megawatt, two-bladed turbine that may generate as much power as the largest commercial offshore turbines.
