The House approved $18 billion in new taxes on the largest oil companies Wednesday as Democrats cited record oil prices and rising gasoline costs in a time of economic troubles.

The money collected over 10 years would provide tax breaks for wind, solar and other alternative energy sources and for energy conservation. The legislation, approved 236-182, would cost the five largest oil companies an average of $1.8 billion a year over that period, according an analysis by the House Ways and Means Committee. Those companies earned $123 billion last year.
