Number: RL34135 Title: Omnibus Energy Efficiency and Renewable Energy Legislation: A Side-by-Side Comparison of Major Major Provisions in House-Passed H.R. 3221 with Senate-Passed H.R. 6 Authors: Fred Sissine, Resources, Science, and Industry Division Abstract: In the first session of the 110th Congress, the House and the Senate passed two markedly different versions of omnibus energy efficiency and renewable energy legislation. This report compares major provisions in House-passed H.R. 3221 and Senate-passed H.R. 6. Key legislative challenges remain. First, there are significant differences between the two bills. Second, because the House and Senate have passed different measures, further action will be required in at least one chamber before a conference committee could be arranged. Third, concerns about certain oil and natural gas provisions, and the lack of measures to support increased oil and gas production, have led the Administration to threaten to veto each bill.
