The global green economy is worth nearly $8 trillion. But the new frontier is the blue economy, and it too is booming. Take clean energy for example. The terrestrial green energy market is vibrant but limited by land available for capacity expansion. Oceans can provide limitless supplies of renewable energy. Offshore wind alone could generate 23 times more power than current total global electricity consumption.

With global offshore wind costs plummeting by 32 percent in 2019 and expected to decrease further, the huge markets of Europe and China could attract $400 billion of investments over the next two decades. Even the shipping industry, once powered by fossil fuels, is catching on.

New market entrant NEOLINE is developing a sail-based maritime transportation business in the North Atlantic, offering decarbonized shipping that is price-stabilized due to significantly lower exposure to fuel prices.
We should look to the seas, especially to sustainable aquaculture, also to feed the world. First-movers like Norwegian company Cermaq are developing facial recognition technology for salmon farming to conduct biological tests on each animal, enabling targeted applications of food and chemicals and reducing environmental and economic waste.
