Ocean and Renewable Energy

The idea of renewable energy has found application since the time of the ancient Egyptians, Romans, Chinese, Indians and more recently in Medieval Europe where windmills and watermills were used. Since the Industrial Revolution, King Coal has found his place and may soon be superseded by Nuclear Energy. Solar and Thermoelectric, Wave and geothermal are slowly finding application also.te  Climate change has been witnessed recently in the past decade and especially in 2020-2021 with the onset of worldwide flooding.  It is postulated that the melting of the polar icecaps would raise sea levels by a couple of meters worldwide. Many island countries like the Maldives may vanish under the waves.  The list goes on. Despite being immersed in a sea of cosmic and terrestrial energy with wind, ocean, solar and other forms, we have not tapped these sufficiently, and rely mostly on fossil fuels.  Unless this pattern changes, there are likely to be serious and calamitous effects on climate and health in the near future.
