Wave Energy Advantages
SIGNIFICANT POTENTIAL SUPPLY
Ocean waves represent our planet's last untapped large-scale energy resource. Over 70 % of the earth's surface is covered with water. The energy contained within waves has the potential to produce up to 80,000 TWh of electricity per year - sufficient to meet our global energy demand five times over.
GREATER PREDICTABILITY
Ocean waves are generated by wind passing over the surface of the sea - a process that often begins many hundreds or thousands of miles from shore. Because waves originate a long way from shore, computer models of wave propagation allow us to accurately forecast incoming waves up to five days in advance.
​
In comparison with wind or solar energy, it's easier to accurately predict how much and when energy can be generated. The timing of when power can be produced from wave energy is not in sync with those from wind or solar, combining the power from these sources acts to even out their combined output, leading to a more predictable and steady energy mix.
​
A diverse energy portfolio will lead to a more stable energy system, reduced variability, greater energy security, and ultimately a lower cost.
LOW IMPACT
​Wave energy is a resource that produces no emissions and requires no fuel. While environmental impacts will need to be studied at a local level, our engagement with experts at the DOE’s Pacific Northwest National Laboratory suggests that Triton should have a negligible impact on the aquatic environment. Wave energy farms require only negligible land use for power substations and can be located far enough from the coast so as to not be seen from land and affect the view.
WORLD WAVE ENERGY
RESOURCE MAP
The world's most energetic waves are found on the US West Coast, Northern Europe, Chile, Australia and New Zealand, but there are many areas around the world where wave energy could prove cost competitive.
WELL MATCHED WITH ELECTRICITY DEMAND
In the US, and in many countries around the world, population and electricity demand in coastal areas is growing faster compared to national averages. In many locations around the world the variability of waves can be seen to match daily and seasonal electricity demand. The net effect is that electricity from wave energy can be used when produced with only minimal requirement to store the energy. In fact, the consistency of energy from waves and the better alignment with grid demand means that much less storage is required compared to an equivalent solar or wind project in most locations. Furthermore, in locations such as the US West Coast, wave energy tends to peak when solar energy is low, and thus wave and solar can actually complement each other to improve power flows within utility grids.
“Wave energy is generally considered to be the most concentrated and least variable form of renewable energy. It is the high power density of wave energy that suggests it has the capacity to become the lowest-cost renewable energy source. The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the oceans via wave power.”
