Using Ocean Heat as a Source of Renewable Energy

The Earth supplies a variety of sources of power to sustain enterprises, homes, as well as individuals, whether it’s the wind, sun, or even tidal waves. In response to the growing threat of the climate change, the environmentalists and researchers have been advocating for renewable energy.

These organizations have also been looking for new ways to absorb the Earth’s energy so that more people can join the clean energy movement. Petroleum, coal, and natural gas still make for a large portion of the world’s energy supply, notwithstanding their recent gains.

However, there have been several promising improvements in recent years. OTEC (Ocean thermal energy conversion), in which the sea’s temperature changes are exploited to generate power, is becoming a more widely investigated renewable resource. Given that the water occupies two-thirds of the Earth’s surface, harnessing this heat might be a huge accomplishment.

What Are the Benefits of Using Ocean Heat as a Renewable Energy Source?

Ocean thermal energy conversion uses the temperature differences in the water to generate renewable energy. Temperatures on the ocean’s surface are substantially warmer than those on the seafloor. Because sunlight cannot reach the bottom, it becomes significantly colder the deeper you go. During the summer, when the sun is shining for most of the day, these temperature disparities are most noticeable.

Solar power is intriguing to those keen on renewable energy because sunlight is free. The sun’s rays warm the Earth and generate energy for solar power, but they also warm the waters. It regenerates every day, and because water covers so much of the Earth’s surface, the OTEC process can produce billions of watts of electricity.

The method of converting these temperature differences into usable energy has taken years of study. Simply explained, OTEC utilizes a series of pipelines to draw colder water from the ocean’s depths. Warm water on the ocean’s surface aids in the heating of cool water, which vaporizes a fluid and, as a result, drives a turbine to generate power.

Warmer climates near the equator are more likely to benefit from this new renewable energy source. The temperatures required for the OTEC systems’ operation are generated in these places. Despite the fact that this is a wonderful source of energy, rising ocean temperatures are still a problem. This can affect aquatic life and lead to population declines all across the planet.
