- OTEC-produced electricity at present would cost more than electricity generated from fossil fuels at their current costs.
- OTEC plants must be located where a difference of about 40 degrees Fahrenheit occurs year round.
- Ocean depths must be available fairly close to shore-based facilities for economic operation.
- Construction of OTEC plants and laying pipes in coastal waters may cause localized damage to reefs and near-shore marine ecosystems
