We recently published a list of the 10 Best Clean Energy Stocks to Buy According to Billionaires. In this article, we are going to take a look at where Sunrun Inc. (NASDAQ:RUN) stands against other top clean energy stocks according to billionaires.

The current overall bearish trend has also dealt a massive blow to the energy sector, which fell by more than 15.7% over the last five days, against a decline of less than 10% by the overall market. This is despite the fact that energy commodities were exempted from President Trump’s sweeping new tariffs – a clear tactic to keep energy inflation in check and in-line with his broader aim to keep energy prices low. The biggest reason for this is the prevailing anxiety about what these tariffs will do to economic growth and, hence, the power demand. The decline in energy stocks also indicates that the market is not expecting any reindustrialization of America to happen in the near term, which appears to be the President’s key aim behind his upending of the entire global trade system.

That said, the global renewable energy industry is growing at a record pace as the world moves ahead with its energy transition to mitigate the impacts of climate change. According to the International Renewable Energy Agency, the global renewable power capacity reached 4,448 gigawatts (GW) in 2024, with an addition of 585 GW just last year. This represented a 92.5% share of the total capacity expansion during the year and marked a record 15.1% rate of annual growth.

The American clean energy sector has kept up with this explosive growth and brought online 48.2 GW of capacity from utility-scale solar, wind, and battery storage in 2024, according to research organization Cleanview. Renewables are set to continue this momentum, and the US Energy Information Administration expects the share of new power capacity to come online this year from renewables and batteries to jump to 93%.

One sector that has particularly garnered accelerated investor interest over the last year is nuclear energy. The International Energy Agency recently revealed that nuclear is set to generate a record level of electricity in 2025. Moreover, on the sidelines of the CERAWeek conference in Houston last month, several major corporations even signed a pledge to support the goal of at least tripling the world’s nuclear energy capacity by 2050.

Another sector that has performed exceptionally well is that of energy storage, which set a new record with 12.3 GW of installations across all segments in the US last year. According to the American Clean Power Association, the industry is on a path to surpass 100 GW of grid-scale storage deployed by 2030. However, the country’s rapidly expanding sector now faces a serious threat since over 90% of lithium-ion energy storage cells deployed in the US storage market last year originated from China, according to Rho Motion, a data research company.

Despite the Trump administration’s best efforts to hamper its growth, the clean energy sector continues to be backed up by an increasing number of hedge funds and billionaires. A great example is how Berkshire Hathaway Energy, a wholly-owned subsidiary of Warren Buffett’s Berkshire Hathaway, has invested over $40 billion in wind, solar, and hydroelectric projects and operates one of the largest renewable energy portfolios in America.
