As the craze of earnings season draws to a close, here’s a look back at some of the most exciting (and some less so) results from Q1. Today, we are looking at renewable energy stocks, starting with Plug Power (NASDAQ: PLUG).

Renewable energy companies are buoyed by the secular trend of green energy that is upending traditional power generation. Those who innovate and evolve with this dynamic market can win share while those who continue to rely on legacy technologies can see diminishing demand, which includes headwinds from increasing regulation against “dirty” energy. Additionally, these companies are at the whim of economic cycles, as interest rates can impact the willingness to invest in renewable energy projects.

The 17 renewable energy stocks we track reported a strong Q1. As a group, revenues beat analysts’ consensus estimates by 5.7% while next quarter’s revenue guidance was in line.

Luckily, renewable energy stocks have performed well with share prices up 15.9% on average since the latest earnings results.

Market Update

Late in 2025 into early 2026, there was hand-wringing around artificial intelligence. For software companies, the fear was that AI would erode pricing power and compress margins as new tools made it easier to replicate what once required expensive enterprise platforms. Crypto investors had their own version of the same anxiety: if AI agents could trade, allocate capital, and manage wallets autonomously, what exactly was the long-term value of today’s crypto infrastructure?

These concerns triggered a noticeable rotation away from these sectors and into safer havens. But markets rarely dwell on one narrative for long. Spring 2026 came, and the focus shifted abruptly from technological disruption to geopolitical risk. The US’ conflict with Iran became the dominant driver of market psychology, and when geopolitics takes center stage, the script changes quickly. Investors stop debating growth rates and start worrying about oil supply, inflation, and global stability.
