According to latest research from Climate Central, a nonprofit research and communications group, average summer temperatures in nearly 230 U.S. cities have increased by 2.4°F between 1970 and 2022. The analysis conducted across 249 cities showed that the West, Southwest, and Northwest regions of the country are most impacted by climate change.

With average summertime temperatures currently 11.1°F higher than they were in 1970, Reno, Nevada, recorded the fastest warming summers. Boise, Idaho, and Las Vegas, Nevada, tied for second place on the list with a 5.8°F increase. Climate Central noted that there are serious health risks associated with the country's current warming trend, especially for children, the elderly, and those with chronic illnesses.

The majority of Americans are aware of global climate change, and according to a Pew Research Center survey, 74% of respondents supported the U.S. taking action to combat the issue, and 67% supported an energy system that puts an emphasis on renewable sources like solar and wind power rather than fossil fuels production.

Meanwhile, the U.S. is determined to address the climate issue by shifting its energy mix away from fossil fuels and toward renewable sources like solar and wind. As per the Sustainable Energy in America 2023 Factbook, the country’s investment in clean energy reached its highest point in 2022 at $141 billion, despite supply chain disruptions, a global energy crisis, and rising interest rates driving up the cost of essential energy commodities. In addition, 40% of the nation's energy came from carbon-free sources last year, setting a new record. The Factbook, published by BloombergNEF (BNEF) and the Business Council for Sustainable Energy (BCSE), also revealed that sales of electric vehicles (EVs) reached nearly 982,000 in 2022, up 50% from the year before.

In addition, the need to switch from fossil fuels to renewable energy sources is not felt equally by all US states. However, a number of states across the country are actively implementing green initiatives and policies in order to save the environment. For more information regarding these states, please refer to our article on the 20 Most Environmentally Friendly States in America.

Greenest Cities in the U.S.

In an effort to help move the country toward net-zero emissions, several American cities are actively contributing to the rapid growth of solar energy. However, the rate at which solar is deployed in various cities across the country is influenced by a number of factors, including climate, state and local policies, and energy prices among others.

Solar energy can currently power more than 23 million homes in the U.S., according to a 2022 report by Environment America Research & Policy Center and Frontier Group. The combined amount of solar installed in the top nine cities is more than what the entire nation had a decade ago.

Between 2014 and 2022, 15 out of 56 cities surveyed recorded a tenfold increase in their solar capacity, per the report. Honolulu, Hawaii is leading the way in solar power. The city has 1,133 watts of solar capacity installed per person. Following it are Las Vegas, Nevada, San Diego, California, Albuquerque, New Mexico, and San Jose, California.

On the other hand, a report by the Solar Energy Industries Association (SEIA) and Wood Mackenzie states that the U.S. solar industry is expected to grow 52% this year, installing nearly 32 gigawatts (GW) of production capacity, with the assistance of investment incentives provided by the Inflation Reduction Act. Moreover, by 2028, it is projected that the United States' total operational solar capacity will soar to 375 GW.

In this context, investors can keep an eye on some of the top solar companies in the nation, like Enphase Energy, Inc. (NASDAQ:ENPH)and First Solar, Inc. (NASDAQ:FSLR).

The report found that the west coast, with 15 western hubs ranking among the top 20, dominates the nation's EV landscape.

Top 20 Most Environmentally Friendly Cities in America

Our Methodology

For the purpose of this article, we made use of two reliable sources. These included 2023’s Greenest Cities in America from the personal-finance website WalletHub and the 2022 Most Sustainable Cities from SmartAsset.

The top 100 American cities were compared by WalletHub based on 28 key indicators of environmental friendliness and sustainability. SmartAsset compared 94 largest American cities in three categories like climate resilience, green efficiency, and transportation to put together a list of the country’s most sustainable cities.

We proceeded to assign a score to each city based on its ranking in each report. For instance, there are a total of 100 cities in WalletHub’s report. The #1 city in that report will get a score of 100/100=1, #2 city will get a score of 99/100=0.99 and so on. We repeated the same scoring methodology for the other report.

The overall score for each city was calculated by adding up their individual scores across the two reports. Finally, we sorted the cities by their total scores and identified the top 20 most environmentally friendly cities in America.
