Ed Markey (D-MA) (R) chairs a House Independence and Global Warming Committee hearing, as an aid holds a chart illustrating the cost of a barrel of oil over the last 7 years, on Capitol Hill in Washington on April 1, 2008. The hearing focused on the current state of oil and gas prices, oil company profits, and the need for clean, renewable fuels to ease demand for oil and cut global warming pollution.
