Question

Which is the type of energy where the energy is harnessed by the heat accumulated on the surface of water?

(a) Wind energy

(b) Wave energy

(c) Ocean thermal energy conversion

(d) Solar energy

I had been asked this question by my college professor while I was bunking the class.

My doubt stems from Ocean Thermal Energy Conversion topic in section Ocean Energy & Geothermal Energy of Energy Engineering

Answer 1

Correct answer is (c) Ocean thermal energy conversion

The best explanation: Absorption of heat from the sun by the seas and oceans, solar radiation causes ocean currents and moderate temperature gradients from the water surface downward especially in tropical waters.
