At this point they're still at the planning stages, but this proposed transnational power grid, designed by Greenpeace, is pretty ambitious.

The basic idea: connect 10,000 wind turbines from over 100 different wind farms in seven countries scattered around the North Sea. That's a lot of wind farms, countries and distances to figure out, but if successful, this shared renewable energy could power 70 million European homes.

The idea of using a massive grid to share wind-generated energy could take care of that pesky problems with wind-power - it's not always windy. By having a grid to share power, a windy day in Scotland can off-set a still day in Germany. There would also be supplements of energy from Scandinavian hydro power.

The plans have been called "ambitious but realistic" by senior official types and I'm guessing these big projects are going to get more popular as the EU tries to meet their 20-20-20 plan (cut 20% of greenhouse gases, get 20% of primary energy from renewables, and knock 20% off of energy use - all by 2020).
