Belgium to Build Artifical Island for Wind Energy
Only around 4 percent of Belgium's energy presently comes from wind power-the rest of the grid is supplied largely by nuclear power. However Belgium, as with Germany and Switzerland, has decided to shut down its nuclear power program by 2025 in the wake of the Fukushima Daiichi disaster in 2011.
The project for the artificial island is part of the state's larger initiative to reorient its power supply towards renewable energy sources. The European Wind Energy Association predicts that, by managing to store energy produced by using wind power, Belgium could expand its wind power capacity to over 4.000 megawatts by 2020.
As an alternative to nuclear power and fossil fuel, wind power has so far faced major problems, largely due to insufficient ways to store the generated power. When the wind dies down, energy production must be backed up by a power source, which makes it expensive to operate.
"We have a lot of energy from the wind mills and sometimes it just gets lost because there isn't enough demand for the electricity," said a spokeswoman for Belgium's North Sea minister Johan Vande Lanotte.
The doughnut-shaped island will store energy by pumping water out of a hollow space in the middle and allowing it to flow back into the reservoir by turning a turbine to generate electricity. The electricity can then be sent back to the mainland.
