Denmark’s government has just agreed to invest in an offshore artificial "energy island". A deal was struck for the government to own 51% of the island with the other 49% owned by the private sector. It's a massive investment both in scope and in physical size, as the island will be the size of 18 soccer fields and house at least 200 offshore wind turbines, and will be located 50 miles offshore in the North Sea. The green energy produced on the island is projected to power three million houses. To protect the island from storms, it will have high seawalls along three sides, with an open port on the fourth side.
