Humanity has always been in awe of the power of the oceans. But it is now time to harvest the energy of the oceans. Is it doable?
Oceans create a vast amount of energy thanks to waves, tides, currents and even differences in salinity and heat levels. Much of the world’s population lives close to coasts, allowing for shorter energy transmission. Marine energy is also renewable and can be used with a low environmental impact. So why isn’t marine energy as big as solar or wind?
“The problem is not technology,” says Krish Sankaran, founding director of Vaasa Energy Business Innovation Centre (VEBIC). “The two main issues are successfully harvesting that energy and distributing it with minimal loss. If you look at coal versus tidal energy, marine power is still expensive.”
