While Republicans in the Senate expressed skepticism about federal renewable portfolio standard legislation, two House lawmakers from opposing sides of the aisle teamed up to introduce a bipartisan bill. The American Renewable Energy Act--introduced last week by Representatives Edward Markey (D-MA) and Todd Platts (R-PA)--would set a 25 percent renewable energy target for utilities by 2025. \u201cEstablishing a federal renewable electricity standard will help to protect our environment as well as promote economic development and energy security,\u201d said Platts. He noted that the measure is similar to a renewable energy law enacted in Pennsylvania and many other states. Markey said the bill would help revitalize manufacturing in the U.S. by expanding the market for wind turbines and other technologies. The bill would create 350,000 new jobs over the next decade, the lawmakers said. Markey also introduced an energy efficiency bill designed to curb nationwide electricity demand 15 percent by 2020.
