The world is going mad for green renewable energy. However, there is one slight problem with Mother Nature providing power, it's unpredictable. The wind is either too strong or too weak and in much of the world, clouds will spoil the strength of the sun. Getting things just right is more luck than judgment. Therefore, energy planners need to build far more windmills to compensate for the lulls and solar panels are only effective in the sunniest of locations.
There is however, one environmental factor that can be relied upon. As regular as atomic clockwork, tides and waves have long been considered the holy grail of renewable energy. Over the years, here have been many attempts at harnessing this reliable power source and in France and Korea, such projects have already been built and Wales is planning a dedicated tidal lagoon.
However, in Scotland, a new project is underway. The MeyGen turbine project is sinking 269 turbines into the Pentland Firth, where they will generate enough power for 175,000 homes.
Atlantis, the company behind MeyGen, has several other projects underway around the world and it expects the Scottish project to begin delivering energy now.
