Senate Committee on Energy and Natural Resources has 20 members, made up of 11 Republicans, 8 Democrats and 1 other. Mike Lee chairs it. Martin Heinrich is the ranking member, which is the senior post held by the minority party. Senate committee seats are held for the length of a senator term, so membership turns over more slowly than in the House. The membership below is generated from the roster this site maintains against clerk.house.gov and senate.gov.
Jurisdiction source: Senate Rule XXV
How business reaches this committee
Senate Rule XXV lists the subjects above and assigns them here. A bill introduced in the Senate is referred to the committee whose Rule XXV jurisdiction covers its main subject, so measures on these topics start with this committee. From there it can hold hearings, amend the text, report the bill to the full Senate, or leave it alone, which is what happens to most bills.
Subcommittees
The committee divides its work among 4 subcommittees:
- Subcommittee on Energy
- Subcommittee on National Parks
- Subcommittee on Public Lands, Forests, and Mining
- Subcommittee on Water and Power
Who serves on it
20 senators sit on the committee: 11 Republicans, 8 Democrats, and 1 independent. That gives the majority 11 of the 20 seats. Mike Lee is the chairman. Martin Heinrich is the ranking member. They come from 20 states.
Following its work
