In this article, we are going to discuss the 10 best clean energy stocks to buy right now.
The Energy Information Administration presented its latest Short-Term Energy Outlook on May 12. According to the agency, US power demand will rise from a record 4,195 billion kWh in 2025 to 4,248 billion kWh in 2026, and then to 4,379 billion kWh in 2027. The soaring demand is primarily driven by the proliferation of data centers dedicated to AI and cryptocurrency, as well as the widespread electrification of homes and businesses.
Meeting such a strong power demand sustainably requires continued investments in clean, cheap, reliable, and renewable sources of power. The EIA forecasts the country’s percentage of renewable generation to rise from around 24% in 2025 to 25% in 2026 and 27% in 2027. As this renewable output grows, the agency expects the share of power generation from coal to slide from 17% in 2025 to 16% in 2026 and then 15% in 2027.
Clean energy continues its dominance also on the global scale and is now in the process of overtaking generation from coal, after virtually drawing level with it last year. The International Energy Agency expects the global renewable power capacity to surge by almost 4,600 GW between 2025 and 2030, with most of this growth coming from utility-scale and distributed solar PV.
The rapid progress of renewable energy is also reflected by the outperformance of the S&P Global Clean Energy Transition Index, which measures the performance of companies in global clean energy-related businesses from both developed and emerging markets. The index has surged by almost 28% since the beginning of 2026, compared to gains of just over 8% delivered by the overall S&P 500 during the period.
With that said, here are the Best Clean Energy Stocks to Invest in.
