The most encouraging aspect of wave energy is that it is a renewable source. Fossil fuels are finite, with danger of running out, but so long as the sun shines, the wind blows and the ocean currents continue to flow, we will have waves.
Energy generated from waves doesn't involve polluting the Earth's atmosphere either, as unlike burning fossil fuels, this energy is completely clean, with no harmful byproducts. Burning fossil fuels is said to provide 85% of the energy we consume, so by switching to renewable energy sources like wave power we will be able to cut our carbon emissions, which are largely responsible for our current climate crisis.
As the oceans cover 70% of the Earth’s surface, wave energy is abundant and widely available; there are many ways to tap into this source (with new technologies readily emerging) and it is considered more consistent and predictable than other renewables such as solar or wind. Not only that, it is noted as the most concentrated form of renewable energy. The energy density is typically around 30-40 kW for every meter (2.2 feet) of wave along the shore, this being the highest power density to be found amongst all the renewables.
Unlike other sources of energy, there is no damage to land when capturing wave power plus it only requires 1/200 of the land area of wind power. Without any roads needed to be built infrastructure, costs are much less.
