The House Science, Space, and Technology Investigations and Oversight Subcommittee and Energy and Environment Subcommittee held a joint hearing April 19 to consider the impact of tax policies on the commercial application of renewable energy technology. The hearing focused primarily on the impact of the Section 1603 Treasury grant program and the general cost effectiveness of renewable energy tax incentives, with Republicans criticizing job creation and costs associated with the programs, and Democrats praising them.
