Today the British company "Blue Energy" unveiled plans for the largest solar power plant in Africa -- and one of the largest in the world.

The new government initiative could lift the land of the rising sun to second place among the world's solar energy markets.

The U.S. will impose new tariffs on cheap Chinese solar panels. The new duties will be low. Analysts say it's not likely to spark a trade war.

On a two-day trip to promote his energy policy, President Obama said the nation must invest in alternative energy or cede leadership to China. He called on Congress to help create jobs by providing more aid to struggling homeowners and investing more in infrastructure.
