Gas Power Leads Both New Capacity and Retirements

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.

Gas Glut Remains, Prices Keep Falling

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?

Turbine Suppliers Pursue a Different Niche: Steel Mills

Steel mills have long recaptured flue gas from the blast furnace to generate local power and steam. But advances in gas turbine technology have taken what was a low-tech means of increasing plant efficiency and given mill owners ways to increase profits through selling electricity and greatly reducing emissions through more efficient combustion.

The End of the Line for Pipe Cleaning with Natural Gas?

Piping at gas-fired plants has long been cleaned using compressed natural gas because of its easy availability. The big problem? It’s also explosive. The fatal 2010 blast at the Kleen Energy plant in Connecticut began a shift toward safer alternatives such as nitrogen and compressed air that is gathering increasing momentum.

Abundant Clean Energy Fuels Brazil’s Growth

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.

Industry Shift in Gas Line Cleaning Practice

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.

Australia Levies Landmark Carbon Tax

After more than a decade debating whether to pass a carbon-limiting law, Australia’s Senate in November voted in a landmark bill that will impose a price on carbon emissions. The country, which accounts for just 1.5% of global carbon emissions, but which is the world’s highest emitter per capita because 80% of its power comes […]

World Energy Outlook Forecasts Great Renewables Growth

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 […]

THE BIG PICTURE: Gas Taxes

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 […]
