Top best answers to the question «Why is ocean thermal energy conversion renewable»
Upwelling of cold water from the deep ocean is replenished by the downwelling of cold surface sea water. Among ocean energy sources, OTEC is one of the continuously available renewable energy resources that could contribute to base-load power supply… OTEC can also supply quantities of cold water as a by-product.

One ocean energy technology that has already been proven to work is Ocean Thermal Energy Conversion (OTEC). By utilizing the natural temperature differences between warm surface waters and deep cold water, this technology, without burning fossil fuels, generates a baseload (24/7) supply of renewable energy.
This means that every day, the oceans on our planet absorb solar energy equivalent to 250 billion barrels of oil, and if we could convert 0.1% of this energy into electricity each day, it would supply a significant proportion of electricity and fresh water requirements for agriculture for tropical, coastal regions of the world.
Ocean thermal energy conversion (OTEC), form of energy conversion that makes use of the temperature differential between the warm surface waters of the oceans, heated by solar radiation, and the deeper cold waters to generate power in a conventional heat engine.
Instead, OTEC is reliable and energy production is defined by area (works best in equatorial areas) and electricity demand. Renewable- OTEC power plants can sustainably provide around four times humanity's current total electrical energy needs. Clean- OTEC is an very clean alternative energy.
Basically, Ocean thermal energy conversion is an electricity generation system. The deeper parts of the ocean are cooler due to the fact that the heat of sunlight cannot penetrate very deep into the water. Here the efficiency of the system depends on the temperature difference. Greater the temperature difference, the greater the efficiency.
Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power. The sun’s heat warms the surface water a lot more than the deep ocean water, which creates the ocean’s naturally available temperature gradient, or thermal energy.
