States With the Largest Increase in Renewable Energy Production

  • Wind and solar have been the most prominent success stories of recent years.
  • Electric power generated from renewables in the U.S. has grown by more than 70 percent since 2010.

One of the most significant trends over the last decade for the economy, society, geopolitics, and the environment has been the rise of renewable energy. Fossil fuels have been the basis of the industrial economy for generations, powering tremendous economic growth but with dangerous consequences for the environment and public health. With the dramatic expansion of renewable energy technologies over the last decade, power sources like wind, solar, and geothermal have offered a more sustainable—and increasingly more affordable—path forward.

Several factors contribute to the expansion of clean energy. For one, technological advancement in renewables has made energy production and storage more efficient than ever before. The renewables industry has also received a boost from public policies and investments enacted by governments worldwide seeking to decarbonize in response to the threat of climate change. These developments have helped bring down renewable energy production costs over time, allowing market forces to spur continued growth in the sector. In all, electric power generated from renewables in the U.S. has grown by more than 70 percent since 2010.

And although growth is occurring across many renewable sources, wind and solar have been the most prominent success stories of recent years. In 2007, wind accounted for about 35 million Megawatt-hours (MWh) of electricity produced in the U.S.; since then, wind production has increased by an average of around 20 million MWh per year, rising to nearly 295 million in 2019. Meanwhile, solar is the fastest-growing of all renewables. Solar production constituted less than 1 percent of renewable energy until around 2010, but experts now project that by 2050, solar and photovoltaic energy will account for nearly half of all renewable electricity production.

Growth in renewable energy production in the U.S. is widespread, but unique features of each region mean that the transition to renewables looks different from state to state. Measured by the proportion of total electricity generated from renewable sources, states in New England and the Western U.S. surpass the rest of the country, largely as a result of renewable-friendly state policies. Vermont generates a remarkable 99.9 percent of its electricity from renewables.

In terms of total electricity produced from renewables, California (97 million MWh), Texas (91 million MWh), and Washington (74 million MWh) are the national leaders. Physical geography explains much of these three states’ strength in renewables. California is the largest producer of geothermal (with the world’s largest geothermal field) and solar (due in part to large installations in the Mojave Desert). With plenty of cheap land and strong wind in many of its regions, Texas dominates the U.S. in wind production. And in Washington, major water features like the Columbia and Snake Rivers provide the basis for the nation’s strongest hydropower sector.

To identify the states with the fastest-growing renewable energy sector, researchers at FilterBuy used data from the U.S. Energy Information Administration to calculate the percentage change in renewable electricity production between 2010 and 2019. The researchers also calculated what percentage of total electricity production is accounted for by renewables, as well as the largest renewable energy source currently.

Here are the states with the largest increase in renewable energy production.
