How this ranking works
Clean Energy isn't a standard sector — its companies are scattered across different industries, so no off-the-shelf classification groups them. This is a curated list of Clean Energy pure-plays in our US universe, each scored on the same transparent quality-growth model — one 0–100 score blending business quality (margins and returns on capital), growth (revenue and earnings), and value (what you pay for them). The table ranks them by that score, highest first, and re-scores every trading day. Click any name for the full grade card, price targets, and analysis.
