It has emerged that Congress is all but abandoning President Barack Obama’s goal of producing fully one-quarter of the nation’s electricity from renewable sources by 2025.

Both the House and Senate are considering legislation that would establish the first national requirement for electric utilities to generate a certain percentage of their power from renewable energy including from wind turbines.

According to a report filed by AP, Senate Energy and Natural Resources Committee is expected to approve energy measures that call for 15% of the country’s power to come from renewable sources by 2021. A huge climate bill, likely to be considered in the coming weeks in the House, would require 20% renewable energy use by 2020.

As per the information available, Obama — both in the presidential campaign and since occupying the White House - has called for a much more aggressive shift to renewable energy. He set a goal of 10% renewable energy use by power producers by 2012 and 25% by 2025. Also, a $787 billion U.S. economic stimulus signed into law in February includes at least $59 billion in new spending and tax credits for the development and expansion of energy technology.  Obama has set a goal to double use of renewable energy by 2012, earmarking $16.8 billion for research into biomass power plants, geothermal energy, solar and wind power and advanced batteries, according to the U.S. Energy Department.

From an industry’s perspective, a company like Siemens believes that it may benefit from the U.S. economic stimulus plan by providing technology to connect planned wind farms to energy users.

“We hope that the stimulus programmes will also provide a significant boost for our technology,” Udo Niehage, head of the company’s power transmission unit, said, according to Bloomberg. He declined to specify what effect the added spending will have on sales.
