Offshore Wind Energy has been foretasted from around 3 GW to 75 GW by 2020 as countries in Europe,Asia and North America heavily support this industry.Onshore wind energy growth on the other hand is expected to slow down as 38 GW of Wind Capacity were installed in 2010 with Western Markets showing a sharp slowdown.Offshore Wind is seeing increasing growth as government heavily subsidize and support Offshore Wind Energy.Though the costs of offshore wind parks are much higher today,they will decrease as the installed offshore wind capacity increases from around 3 GW today to around 75 GW which is being foretasted globally by 2020.Note every industry sees costs declining with large capacity except the mature industries.For example Wind Energy has seen a 10% decline in costs for every 100% increase in installed capacity.Note offshore wind projects offer even more Wind Energy Advantages than normal Land Based Wind Farms.The only problem facing offshore wind power is high costs as the industry still is on the learning curve.However as companies gain experience and build capacity,the prices will be cut as costs come down and volumes increase.European Wind Companies are leading the pack as almost 80% of the current global capacity has been installed in Northern Europe.The opportunity is so large that South Korea shipbuilders like Samsung,Daewoo and Hyundai are investing heavily in this area.
