A 100% Renewable Energy Future Is Possible, & We Need It

At-a-Glance: 

A transition to renewable energy is not just one of the most consequential tools at our fingertips to act on climate, but also represents a great opportunity to increase control over our energy choices, improve the health of our communities and the planet, create jobs and wealth, and much more.

Key Takeaways:

  • A new study called On the Road to 100 Percent Renewables examined how two dozen state members of the U.S. Climate Alliance (USCA) can meet all of their electricity needs with renewable energy — while decarbonizing other sectors of the economy and ensuring equitable benefits to all communities.
  • Using the Regional Energy Deployment System (ReEDS) electricity model from the National Renewable Energy Laboratory, the study found that coal generation in member states essentially disappears by 2040 in USCA states as solar and wind generation grows exponentially.
  • The model found that the US would be about 73% renewable by 2040 because fossil fuel plants will still exist in other states and the power grid is so interconnected that generation is shared across state lines.

Path to 100% Perspective:

The Path to 100% is working to identify the fastest, most cost-effective, most reliable ways to decarbonize electricity — not just city by city, but across entire states and nations. As the article states, increasing the reliance on renewable energy sources, like wind and solar, will be critical to success. We must also determine a plan to realistically phase out fossil fuel plants which provide more consistent, reliable power around the clock. Renewable sources can be intermittent, so battery technology will need to improve and we will need to build flexible power plants that can run on sustainable fuels like hydrogen. The path will not be the same everywhere and the timeline may vary, but a 100% renewable energy future in the United States is possible by 2050 if everyone works together.
