WIND ENERGY UNITED KINGDOM Of winners and losers It’s offshore season again in the UK. While numerous large projects are under construction at sea, on land there is little to get excited about. Far from offering suitable infrastructure, many ports can boast only of their great potential. ile hammers work tirelessly off the southeast Manufacturers and suppliers coast of England. At a fever pitch, construction lacking Pteams drive piles into the seabed, lay cables, and assemble turbines.
