Offshore wind farms work like hurricane speed bumps and are a new way to kill a hurricane's power by transforming its energy into electricity. http://news.stanford.edu/news/2014/february/hurricane-winds-turbine-022614.html Subscribe to The Daily Conversation null Facebook http://www.facebook.com/thedailyconversation Google+ https://plus.google.com/100134925804523235350/posts Twitter http://www.twitter.com/thedailyconvo According to his advanced climate-weather computer model, Stanford researcher Mark Jacobson found that installing massive offshore wind turbine farms in the path of a hurricane diminishes hurricane wind speeds by up to 92 mph and storm surge by up to 79%. The catch is that the simulation used 300 gigawatts of installed wind turbine capacity, when the biggest offshore wind farm man has built to this point is the London array at only 630 megawatts of installed capacity, nearly 500 times smaller than the one Jacobson used in the model. Plus, the London Array also cost $3 billion. So, scaling up to a wind farm the size of which was used in the study would cost hundreds of billions of dollars. But think of the different problems this could simultaneously eliminate. Hurricane Sandy caused over $80 billion in damages as did Katrina, which basically wiped out New Orleans. With climate change making these storms more intense and more frequent, one idea to protect cities has been the construction of giant sea walls at a cost ranging from $10-30 billion per city. But a giant wind farm could protect entire coastlines, while paying for itself through the energy it produces and CO2 emissions if reduces. A 300 GW array-like the one in the study would create enough electricity to power around 100,000,000 homes. If building one of these mega farms in the gulf coast could simultaneously stop the threat of hurricanes in the region and provide the power for a large portion of the country in a clean, renewable way, why would we not take a hard look at this? If we're going to solve these big, 21st-century problems, we need to start thinking boldly. We should build off Mark Jacobson's study with a much more in-depth examination to both confirm these findings and to make sure that stopping hurricanes wouldn't have unintended negative consequences on the ecosystem more broadly. But if the data continues to look as good as it does right now, I say we go for it and construct two, 300 GW arrays: one in the Gulf of Mexico and one off the Eastern Seaboard.
