The U.S. military is growing increasingly concerned that proposed wind farms can disrupt or block radar designed to detect threats and protect America's skies, a problem that is stalling the alternative energy projects around the country. A top U.S. general told Congress on Thursday that federal agencies need to work better together on a formal vetting process for the wind projects.

A group of environmental organizations and opponents of wind energy projects say they likely will file suit if the federal government approves the proposed Nantucket Sound wind farm. A 60-day notice of violations of the Endangered Species Act was sent this week to Massachusetts Secretary of State William Galvin and to the U.S. Interior Department and other federal agencies that have reviewed Cape Wind's plan to build 130 wind turbines in the sound.

Cape Wind critics threw up an eleventh-hour roadblock this week, accusing two U.S. government agencies that approved portions of the proposed offshore wind energy project of violating federal laws. "We put them on notice," said Lisa Linowes, executive director of the Industrial Wind Action Group, which tracks the benefits of wind energy projects. Her group and eight others filed a 60-day notice of violations with U.S. Interior Secretary Ken Salazar.

U.S. companies are getting squeezed out of the big Chinese wind-power market even as Dallas investors are bringing Chinese firms here via a big wind farm in Texas, according to a new industry report.

A bipartisan coalition of 29 governors is pushing to solidify a national standard for renewable power to boost green job creation, environmentally friendly economic development and energy independence. In a report delivered Tuesday to President Obama and Congress, the Governors' Wind Energy Coalition asked lawmakers to require utilities to obtain at least 10% of their electricity from alternative energy such as wind, solar and biofuels by 2012.

A coalition representing governors of 29 states -- including Maine's Gov. John Baldacci -- is urging the federal government to take steps to boost wind energy, such as a renewable energy standard requiring utilities to produce at least 10 percent of their energy from renewable sources by 2012. The bipartisan Governors' Wind Energy Coalition plans to make the recommendations Tuesday in a report to Congress and the White House. The Associated Press obtained a copy of the report ahead of its official release.

A federal panel charged with assessing Cape Wind's impact on dozens of historic sites includes an architect, an anthropologist and a Texan who runs one of the nation's largest beer distributors. Last week, the Advisory Council on Historic Preservation identified a five-member Cape Wind review panel, as a final federal ruling on the controversial offshore wind farm appears on the horizon.

A group of Wampanoag tribes who say they've been cast aside on issues from the Nantucket Sound wind farm to the future of gaming are breaking away to create a new council to deal with state government. The state-recognized tribes are calling on Gov. Deval Patrick to disband the Massachusetts Commission on Indian Affairs, the current liaison to state tribes.

U.S. banks had looked forward to a huge "cap-and-trade market" a system where companies would buy and sell the right to emit gases blamed for warming the planet. Many hired carbon traders, picked up assets, and trained members of energy desks to deal in emissions markets. But prospects for a broad U.S. carbon market have dimmed. U.S. Senator Lindsey Graham, a Republican working on a compromise climate bill, declared economy-wide cap-and-trade "dead" this month.
