Wave energy: ''flexible'' energy mix needed for renewable future

"It is the last and largest untapped resource of renewable energy," says Rémi Gruet, CEO of Ocean Energy Europe (OEE), an industry body for ocean renewables, talking about the potential offered by wave energy–which uses the motion of the ocean to generate electricity. Just how large remains unclear. In 2011, the UN Intergovernmental

A short history of wave energy

Wave energy is a renewable energy source that harnesses the power of ocean waves to generate electricity. As a clean, abundant, and largely untapped resource, it has the potential to play a significant role in the global transition towards sustainable energy systems. In this section, we will explore the basics of wave energy and its potential

WHY WAVE POWER IS THE NEXT ESSENTIAL STEP IN THE ENERGY

Here are 10 reasons why wave power is a game changer in renewable energy. 1. Wave energy is predictable. Grid operators have shifted less than 13% of the power they generate from fossil fuels to wind and solar because they can''t always predict how much power they will be able to pull from those resources. The wind dies down, a cloud blocks

Could wave energy meet the world''s electricity needs?

In theory, yes. Wave energy globally could meet the world''s annual electricity needs, if it was fully harnessed, scientists have estimated. Indeed, the waves around the United States coasts could provide 66% of the country''s electricity, according to the US Energy Information Administration.
