Seven months after a trade investigation was launched, American solar companies and Chinese solar manufacturers will finally get a clear picture of the challenges ahead.

No form of energy really emits zero emissions, and that’s a point that’s both missed by casual advocates and overstated by strident critics.

Back in 2009, Deutsche Bank Climate Change Advisors (“DB”) published a study tracking 270 major climate policies in 109 countries. The study concluded that successful programs were those that offered investors “TLC” — transparency, longevity, certainty — a comprehensive, stable, and predictable set of rules that infused markets with a sense of clarity and security. The research went on to find that the United States lacked TLC and was lagging behind other countries, notably China and Germany. A more recent DB paper found little to cheer about at the Federal level in the U.S. Referring to the gridlock in Congress on energy policy, the paper noted “…while Congress stumbles, the U.S. stands to fall behind.”

Construction has begun on what will become Chile’s largest wind farm, a 115-megawatt development in the Antofagasta region in the northern part of the country.

Affirming its commitment to the development of renewable energy resources, the Arizona legislature recently passed legislation exempting the sale and/or use of Renewable Energy Credits (generally referred as “RECs”) from Arizona’s transaction privilege tax, which operates similar to a sales tax. Given that Arizona’s state transaction privilege tax is over seven percent in most counties, and that city tack on an additional 2 to 3 percent tax, the decision to exempt the sale of RECs from a 10 percent tax is a significant development that should encourage the development of renewable energy in Arizona.

A looming decision that threatens to derail Europe’s biofuels industry could reverberate all the way to Asia.

For many dams currently being removed in the U.S., the primary reason behind this work is the need to protect fish and restore their habitat. This article provides case studies of the removals under way and the context under which these decisions were made.

In what may be the most significant renewable energy policy development worldwide in years, Japanese authorities are circulating proposed feed-in tariffs that-if confirmed by the Minister of Trade later this month-could lead to a crash renewables program.

At the recent Fortune Brainstorm Green conference which I attended in Laguna Niguel, California, there was a host of U.S.-focused presentations and conversations. The ongoing themes and dialogue provided significant insights into the current state of affairs in the U.S. clean-tech market, including:

Knowledge has always been power, but how that information is stored has emerged as one of the most challenging issues facing the evolution of technology.
