The world is going mad for green renewable enerfy. However, there is one slight problem with Mother Nature providing power: it's unpredictable. Goldilocks conditions aren't guaranteed. The wind is either too strong or too weak and in much of the world, clouds spoil the strength of the sun. Getting things just right is more luck then judgment. Therefore, energy planners need to build far more windmills to compensate for he lulls and solar panels are only effective in the sunnies of locations.
There is however on environmental factor that can be relied upon. As regual as atomic clockwork, tides and waves have long been considered the holy grail of renewable energy. Over the years there 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 in underway. The MeyGen turbine project in sinking 269 turbines into the Pentland Firth, where they will generate enough power for 175,000 homes (400 megawatts),
With public opinion being largely against wind turbines and solar cells taking up a great deal of valuable real estate sinking windmills in the sea, which is 800 times more dense than air, may finally be the solution we've been looking for.
