Source of wave and tidal energy?

In addition to its abundant solar, wind and geothermal resources, the Pacific Northwest is also uniquely situated to capture the renewable energy of the ocean. Special buoys, turbines, and other technologies can capture the power of waves and tides and convert it into clean, pollution-free electricity. Like other renewable resources, both wave and tidal energy are variable in nature. Waves are produced by winds blowing across the surface of the ocean. However, because waves travel across the ocean, their arrival time at the wave power facility may be more predictable than wind. In contrast, tidal energy, which is driven by the gravitational pull of the moon and sun, is predictable centuries in advance.

The technologies needed to generate electricity from wave and tidal energy are at a nascent stage, but the first commercial projects are currently under development, including some in the Pacific Northwest. Like most emerging energy technologies, wave and tidal technologies are currently more expensive than traditional generating resources, but with further experience in the field, adequate R&D funding, and proactive public policy support, the costs of wave and tidal technologies are expected to fol-low the same rapid decrease in price that wind energy has experienced.

Tidal gravity from the moon and sun, as long as the moon orbits us and we orbit the sun, there will be tidal energy.

Tides come from the moon orbiting the earth. They’re renewable because the moon isn’t going to stop.

Hydro-electric potential is made out of water by making use of heating it to transform it into steam to rotate the turbine. photograph voltaic potential is classified by making use of making use of photograph voltaic cells that are made out of Platinum. Tidal potential is won from sea through intense and coffee tides. Wind potential is accessed by making use of making use of kinetic potential of wind to rotate the turbine. those are fairly costly for use.
