Surging supply and plummeting prices during 2011 have worked a sea change in America’s energy policies and use of natural gas. How long can it go on?

Timing is (almost) everything when it comes to building new power plants. Nobody knows that better than AEP, which finally got a happy ending to a story that took over a decade to complete.

The 2000s saw dramatic growth in gas-fired power generation capacity. But, surprise–this growth was also accompanied by the retirements of numerous older gas-fired plants.

The rapid growth of gas extraction by hydraulic fracturing has drawn increasing allegations of property damage and health risks. In many cases, these allegations are being followed by a wave of lawsuits.

The National Fire Protection Association has issued a new standard for gas line cleaning in response to the urgent recommendations prepared by the U.S. Chemical Safety Board.

Brazil’s power industry has long been dominated by its vast hydro resources, which historically have accounted for over 80% of the country’s generation capacity. With engineering marvels like the massive Itaipú dam and the proposed Belo Monte project, the country is a leader in the development and use of hydroelectricity on a grand scale. But as the 2001 energy crisis proved, dependence on a single source leaves the country vulnerable to severe shortages. Thanks to government programs designed to take advantage of the country’s favorable climate, Brazil is committed to diversifying its energy mix while continuing to maintain a renewable energy focus.

After years of political wrangling, coal-rich Australia in November passed legislation that will require the nation’s top 500 polluters, starting in July 2012, to pay a tax at a fixed price of A$23 (US$23.50) per ton of carbon. The tax increases 2.5% annually until 2015, when an emissions trading program will begin. With the Kyoto […]

Driven by policies to limit carbon emissions, as well as government subsidies, the share of worldwide nonhydro renewable power is set to grow from just 3% in 2009 to 15% in 2035, the International Energy Agency (IEA) forecasts in its recently released World Energy Outlook 2011. Under the same scenario—which assumes that carbon pricing, explicit […]
