CETY vs ORA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CETY and ORA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CETY and ORA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Clean Energy Technologies, Inc. (CETY) is a small clean-energy technology company headquartered in Irvine, California, that designs and sells systems to turn wasted heat and waste materials into usable power. Its core products are Waste Heat Recovery Solutions built around the patented Clean Cycle generator, an Organic Rankine Cycle (ORC) machine that converts low-grade heat from industrial processes into electricity, and Waste-to-Energy solutions under its HTAP pyrolysis platform, which converts biomass and organic waste into renewable gas, power, and biochar. The company also pursues battery energy storage (BESS) projects and targets sectors such as cement, steel, glass, oil and gas, biomass, anaerobic digestion facilities, and, more recently, data centers.

Ormat Technologies is a vertically integrated geothermal and energy-storage company. Its core business is generating baseload renewable electricity from geothermal energy: tapping underground heat to drive turbines that produce around-the-clock power, unlike intermittent solar and wind. Ormat operates its own fleet of geothermal and recovered-energy power plants and sells the electricity under long-term contracts to utilities and other offtakers, which it calls its Electricity segment. It also designs, builds, and supplies geothermal power-plant equipment and engineering services to third parties (its Product segment), and it has grown a fast-expanding Energy Storage segment that builds and operates battery storage assets providing grid services. Founded in 1965 and headquartered in Reno, Nevada, Ormat is one of the few pure-play geothermal companies of scale and is positioned as a provider of firm, dispatchable clean power, an increasingly valued attribute as grids add intermittent renewables and face rising demand.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CETY drivers: ORC waste-heat-to-power niche; HTAP waste-to-energy platform.
• ORA drivers: Baseload renewable power; Long-term contracted cash flows.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: CETY is a highly speculative micro-cap and the risks are severe. For ORA, geothermal projects are capital-intensive, geologically risky, and slow to develop, with long lead times and the chance that resource performance disappoints.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CETY if you believe its drivers more; ORA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CETY and ORA guides.

CETY. All figures are approximate and tied to the asOf date; because CETY has had late regulatory filings, published financials may be dated, so verify the latest available numbers and filings before acting. With negligible revenue and ongoing losses, price-to-earnings and similar ratios are meaningless here. The stock is valued on narrative (technology, partnerships, pipeline) and on the market's read of financing and delisting risk, not on current fundamentals. Treat any position as high-risk speculation.

ORA. Ormat combines a stable, contracted Electricity segment with lumpier Product revenue and a growing Storage business. Its valuation reflects predictable geothermal cash flows and clean-baseload scarcity value, balanced against high capital intensity, leverage, and sensitivity to interest rates and renewable-energy policy.

Headline figures (approximate, Jul 2026): CETY shows revenue trend Very small and declining; roughly $2 million in 2025, down about 11% year over year (approximate, verify live), profitability Unprofitable with widening losses; 2025 net loss was materially larger than 2024, so no positive earnings to value against, balance sheet Thinly capitalized; likely reliant on external financing that can dilute existing shareholders (verify the latest filing), market cap tier Micro-cap / speculative; verify the current figure live because the low-priced share moves sharply; ORA shows revenue (ttm) ~$900 million, operating margin ~20%+, net income (ttm) positive, generating capacity ~1+ GW across geothermal and storage.

CETY and ORA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CETY and ORA exposure against your real portfolio. It is not an investment adviser.
