BOSTON (AP) — Leaders in the Massachusetts Senate have unveiled a bill designed to ramp up the state's reliance on renewable sources of energy, including offshore wind and hydropower.

The plan detailed Friday establishes more aggressive energy targets than a similar bill approved by the House earlier this month.

The Senate bill would set a goal for utilities to sign long-term contracts of 2,000 megawatts of offshore wind energy. That's a higher goal than the 1,200 megawatts of offshore wind called for in the House bill.

The Senate bill also sets a separate goal of 1,500 megawatts from other sources of renewable energy including hydropower. That's also higher than the goal of 1,200 megawatts from other renewable sources in the House bill.

The Senate is expected to debate the bill next week.
