What percent of US electricity is renewable?

As of 2023, renewable energy generates 25% of US power, marking a significant milestone in the country’s transition towards cleaner energy sources. This achievement is a result of the growing investment and adoption of solar, wind, and hydro power, which are becoming increasingly cost-competitive with fossil fuels and contributing to a reduction in greenhouse gas emissions.

Introduction to Renewable Energy in the US

The United States has made significant progress in recent years in increasing its renewable energy production, with renewables now accounting for a substantial portion of the country’s energy mix.
