Earlier this month, the Obama administration decided to delay the decision on approval of the XL pipeline until 2013, ostensibly to further study the pipeline’s potential environmental impacts.

The fight over the pipeline, which would transport tar sands crude from Canada to US refineries in the Gulf of Mexico region, has become a symbol of a broader argument.

Energy efficiency is not a sexy topic, so when the U.S. Department of Energy and the Ad Council teamed up in July for a national consumer education campaign that includes messaging like “Save Money, Save Date Night” and viral-bound videos of a couple throwing all their worldly possessions down a cliff to cement the point that wasting energy is like wasting (in spectacular fashion) money, it was at least a refreshing take on an historically dull issue.

Oceana, the NGO which, according to its website, is the largest organization focused soley on ocean conservation, has been running a new ad campaign in Washington, DC since about the first anniversary of the BP Deepwater Horizon accident (mid-April). I see the posters frequently on my ride to and from work on the DC Metro. The campaign is titled What If It Happened Here?, and depicts a DH-like drilling platform fire and the consequences – oil slicks, deployed booms, oiled birds – adjacent to the Golden Gate Bridge, the Statue of Liberty and the Washington Monument…

The choices government and business leaders make to resolve the tightening choke point between rising energy demand and declining freshwater reserves will form the central strategic focus of the next era of China’s unfolding development.

As unrest in North Africa and the Middle East enters a fifth month since the first sparks of the Tunisian Revolution last December, oil prices are starting to dominate the political discourse. In the UK, Energy Secretary Chris Huhne warned of a 1970s-style oil shock that could cost the UK economy £45 billion over two years. Closer to home, last week’s Financial Mail cover story on oil – the three letters that threaten economic growth – argued that a sustained high oil price threatens to completely stall the global recovery.

BP's 2010 sustainability report tries to take the spill head-on, but stakeholders have even bigger questions in mind.

Externalities abound, but perhaps nowhere more so than with coal. Let's hope decision-makers are poised to act.

Why energy rationing, not seen in the UK since WWII, may be exactly what's needed to jumpstart climate action.

The oil industry should, instead of isolating one culprit, commit to addressing systemic failures that led to the spill.

Energy and water are difficult issues in their own right, but they're on a collision course in places like China.

Whatever happened to leadership and climate responsibility which reflects a company’s values and principles?

How will the Deepwater Horizon accident affect the future of the oil and gas industry?
