Green Energy Stocks: 11 Companies Compared on Ethics

Enlight Renewable Energy and ITM Power share the highest average in this selected eleven-company comparison, followed by First Solar and ReNew Energy. That is a result from Mashinii's recorded ethics scores, not a forecast of share returns or a claim that these are the best investments for everyone.

Score records rechecked on 8 October 2026. The underlying records shown below are dated April 2026; a review date does not make those records new.

Correction — 13 September 2026: Removed an invalid entry named “score” and recalculated the rankings. Unavailable dimensions are excluded from averages and are no longer counted as neutral scores.

Each recorded score ranges from −100 to +100. The average is the sum of available scores divided by the number of scored dimensions; the coverage column shows that number out of eleven. “—” means no score is available and is not zero. A recorded zero is neutral within this scoring system, not proof that a company has no problems.

Ranks compare only the companies listed here, not every company in the sector. Coverage differs between companies, so an average alone is not a complete like-for-like comparison or an investment recommendation. Exact ties share a rank; displayed averages are rounded to one decimal place. Where highest or lowest scores tie, one dimension is shown.

Which green energy companies are the most ethical?

The answer depends on which companies, evidence and dimensions are compared. This table uses Mashinii's records for the eleven named businesses. It does not represent a consensus among watchdog organisations, and a high climate score does not establish a strong labour or sourcing record.

The SEC's investor bulletin on ESG funds explains that there is no single SEC ESG score and that private ratings can differ substantially. Check the methodology behind a rating rather than treating different providers' numbers as interchangeable.

Does a higher ethics score make a better green-energy investment?

Not by itself. This comparison contains no valuation, earnings forecast or assessment of whether a share price compensates for financial risk. It also does not establish that a company's entire revenue comes from renewable energy.

If researching an investment, use the company's current filings to check its business mix, finances and risks separately. An ethics screen can narrow the questions you want to investigate; it cannot replace that work. Our guide to ethical-investing returns explores the distinction.

How to use this comparison

Use these scores as a route into the underlying evidence, not as a substitute for reading it. Open a company profile, choose the values that matter to you, and follow its direct citations. Company records can be incomplete, and a neutral score should never be read as an endorsement.
