Maine Public: Maine codifies new goal of 100% clean energy by 2040

June 18, 2025
Maine has officially accelerated its 100% clean energy goal by a decade, reports Maine Public.

“The new law would require the state’s energy office to expand Maine’s existing Renewable Portfolio to 90% by 2040, focusing on rooftop solar, wind and other clean energy produced here in the state. The remaining 10% will be dedicated to a new category of energy resources.

 

Achieving 100% clean electricity could lower average household energy costs by about $1,300 per year, according to a study conducted by the state’s energy office last year. That’s because pricing can be volatile for fuels sourced out-of-state, like natural gas and heating oil.”

About the Alliance

Launched on June 1, 2017 by the governors of Washington, New York, and California to help fill the void left by President Trump’s initial decision to withdraw the U.S. from the Paris Agreement, the Alliance has grown to include 24 governors from across the U.S. representing approximately 60% of the U.S. economy and 55% of the U.S. population. Governors in the Alliance have pledged to collectively reduce net greenhouse gas emissions by at least 26-28% by 2025, 50-52% by 2030, and 61-66% by 2035, all below 2005 levels, and collectively achieve overall net-zero greenhouse gas emissions as soon as practicable, and no later than 2050. 

 

The Alliance’s states and territories will continue to advance innovative and impactful climate solutions to grow the economy, create jobs, and protect public health, and have a long record of action and results. In fact, the Alliance reduced its collective net greenhouse gas emissions by 19% between 2005 and 2022, while increasing collective GDP by 30%, and is on track to meet its near-term climate goal by reducing collective GHG emissions 26% below 2005 levels by 2025. The coalition’s states and territories are employing more workers in the clean energy sector, achieving lower levels of dangerous air pollutants, and preparing more effectively for climate impacts and executing more pre-disaster planning than the rest of the country.
