As the U.S. has undergone a rapid and massive shift to natural gas from coal, one benefit has gone almost entirely overlooked: the amount of water needed to cool the nation’s power plants has dropped substantially.

Before world oil prices collapsed late last year, shop owners closest to the banks of the Rio Grande River in Piedras Negras joked that they could hear the groans of Texas drilling rigs advancing toward their fast-growing northern Mexico city.

Researchers have been warning about future water scarcity for decades, but new data reveals a majority of the world’s largest aquifers are already running out of water.

The past decade has brought ground-shaking changes to global energy markets. The unconventional fuel boom has unexpectedly reduced U.S. dependence on oil imports, while in the Asia-Pacific region, energy-constrained nations are increasingly reliant on foreign sources to meet their soaring demand. With the U.S. slated to export liquid natural gas (LNG) to Asia as early as 2017, a new energy era has come.

With the Obama Administration moving forward on emissions reductions, the deadline for drafting the Sustainable Development Agenda, and a highly anticipated global climate summit in Paris, 2015 promises to be a crucial year for climate policy. “In many ways, last year was the year of building momentum, and this is the year of getting the work done,” said Lisa Friedman, deputy editor of ClimateWire, at the Wilson Center on January 5. [Video Below]

On the heels of a landmark U.S.-China climate agreement, 2015 will be a critical year for China’s environmental and energy policy. A revised and much stricter Environmental Protection Law went into force on January 1; new amendments to the Air Pollution Law are likely to be put in place; and the National Development and Reform Commission will draft a new five-year plan.

One in five African states produce hydrocarbons, and most of these are heavily dependent on oil and gas revenues to finance their governments and generate foreign exchange. Further, an emerging group of East African states are waiting on international oil companies to develop new oil and gas reserves. But Africa’s record using non-renewable oil and gas resources to trigger economic and social development is poor – and plummeting prices may portend more instability to come.

Until two years ago, when the National Wildlife Federation pointed out their presence, the 61-year-old steel oil pipelines running beneath the fast-flowing Mackinac Straits between Lake Michigan and Lake Huron were like nearly every other piece of North America’s energy transport network: out of sight and out of mind.
