As the planet increasingly looks to curb greenhouse emissions, it is not uncommon to see solar and windenergy take center stage in the debate. However, a sometimes-neglected form of energy could play a major role in preparing economies for a future that is less dependent on fossil fuels—tidal energy.
The potential energy that could be harvested from tidal movements on a global scale is enormous. It is estimated that around 1 terawatt of exploitable power is stored in the world’s oceans. This would be enough to power 10 billion 100-watt lightbulbs at once.
