Explain ocean thermal energy

1.	Explain ocean thermal energy
Answer» \tThe surface of the ocean is at a higher temperature than the layers below. This is because of the sun\'s heat warms up the upper layers of the sea.\tThis temperature difference is exploited to generate energy\tA minimum temperature difference of 20 degrees C is needed between water at the surface and at a depth of about 2 km.\tThis requires Ocean Thermal Energy Conversion plants which converts ocean thermal energy to electricity.\tThe water at surface of the ocean which is at higher temperature vaporizes liquid ammonia.\tThe vapour ammonia now moves the turbine which generates electricity.\tThe vapour ammonia then, is condensed using the water at the bottom layers of the ocean. It now again becomes liquid ammonia.
