Oregon Second District Congressman Greg Walden advocated modernizing America’s hydropower infrastructure during a subcommittee hearing.  The Hood River Republican chairs the House Energy and Commerce Committee.  Walden told the group at the hearing that there are opportunities to expand hydropower across the country but there are regulatory challenges to deal with.  Walden added the electricity generated by hydropower is “as clean and renewable as it gets,” and there needs to be greater transparency and accountability in the regulatory processes affecting hydropower.
