"The top federal regulator of oil and gas pipelines is facing withering criticism for her ties to industry and her agency's floundering response to recent oil-pipeline spills in the Midwest and last week's deadly gas pipeline explosion in California."

"The world's largest solar power plant cleared an important hurdle on Wednesday, laying the groundwork for a dramatic expansion in solar energy generation in the United States and around the world.
