When he entered Congress, Tonko said he wanted to focus on the issue he said he knows best – energy policy. He sponsored a bill to get $800 million research program in wind energy technologies, which would benefit GE in his district. He also wanted to create a research program to improve the efficiency of gas turbines used in power generation systems that convert heat into energy. In 2010, Tonko got a provision in a House-passed bill, following the BP disaster in the Gulf of Mexico, to prevent future spills and help small businesses in spill research. In 2011, he sponsored an amendment seeking to protect the Environmental Protection Agency's authority to regulate carbon emissions.
