<\/strong>Offshore wind turbines generate electricity the same way as their land-based counterparts: Wind blows on the blades, causing them to rotate. This spins a drive shaft that is connected to a generator, and the generator converts the kinetic energy into electrical energy.&nbsp;<\/p>\n\n\n\n<p>In an offshore system, this electricity is then transported to land via cables on or buried under the seabed.&nbsp;<\/p>\n\n\n\n<p>If the turbines are located near the shore, where the water is less than 200 feet deep, they may be built on a rigid foundation that extends into the ocean floor. In deeper waters, they are mounted on <a href=\"https:\/\/www.freethink.com\/energy\/floating-wind-turbines-105893\">floating structures<\/a> that are attached to anchors resting on the seabed.<\/p>\n\n\n\n<p><strong>Current status:<\/strong> Wind is currently the top offshore renewable, with a total capacity of about <a href=\"https:\/\/www.statista.com\/statistics\/476327\/global-capacity-of-offshore-wind-energy\/\">72 gigawatt (GW)<\/a> worldwide as of 2023 (\u201ccapacity\u201d refers to the maximum amount of electricity a system can generate if operating full time under optimal conditions).<\/p>\n\n\n\n<p>That\u2019s enough offshore wind to supply <a href=\"https:\/\/www.doi.gov\/sites\/doi.gov\/files\/migrated\/whatwedo\/energy\/ocs\/upload\/slides-POCS-2.pdf\">19 million<\/a> average American homes with power annually and a tenfold increase over global capacity in 2013.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>&#8220;You can power almost the entire United States with offshore wind on the East Coast.&#8221;<\/p><cite>Mark Z. Jacobson<\/cite><\/blockquote><\/figure>\n\n\n\n<p><strong>The benefits<\/strong>: Wind speeds are higher and more stable over the ocean than over land, which means offshore turbines are typically more efficient and consistent. They\u2019re also scalable, with plenty of suitable locations for the structures across the globe.<\/p>\n\n\n\n<p>\u201cYou can power almost the entire United States with offshore wind on the East Coast,\u201d Mark Z. Jacobson, director of the Atmosphere and Energy Program at Stanford University, told Freethink.<\/p>\n\n\n\n<p>\u201cIf you put it down in the Gulf Coast and lower East Coast, you can help reduce hurricane damage, too,\u201d he adds, citing a <a href=\"https:\/\/www.nature.com\/articles\/nclimate2120\">2014 study<\/a> he led. \u201cIf you keep the turbines running and there are lots of turbines, you can actually extract energy from the hurricanes and reduce their wind speeds and the storm surge, so there is this dual benefit.\u201d<\/p>\n\n\n\n<p><strong>The drawbacks<\/strong>: Offshore wind farms are more expensive and complicated to build and maintain than their onshore counterparts. This is particularly true for floating offshore wind turbines.<\/p>\n\n\n\n<p>More research is needed to fully understand how offshore wind turbines affect the environment, too. The <a href=\"https:\/\/tos.org\/oceanography\/article\/offshore-wind-farm-artificial-reefs-affect-ecosystem-structure-and-functioning-a-synthesis\">bases of offshore turbines<\/a>, for example, can act as <a href=\"https:\/\/www.freethink.com\/energy\/artificial-coral-reefs\">artificial reefs<\/a> that provide homes for marine life and draw new species into an area. At the same time, this increase in biodiversity can disrupt the existing ecosystem and negatively impact commercial fish stocks.<\/p>\n\n\n\n<p>Scientists have identified ways to minimize some known negative impacts of offshore turbines on the environment, though.&nbsp;<\/p>\n\n\n\n<p>Construction projects can be timed so that they <a href=\"https:\/\/www.eenews.net\/articles\/dominion-pauses-offshore-turbine-installation-for-whale-migration\/\">avoid disrupting whale migrations<\/a>, for example, and the number of bird fatalities from collisions with turbines can be reduced <a href=\"https:\/\/climate.mit.edu\/ask-mit\/do-wind-turbines-kill-birds\">by 70%<\/a> if we simply paint one blade black (though Jacobson notes that \u201cthe number of bird deaths are really trivial in comparison to fossil fuel bird deaths\u2026because fossil fuels kill birds from mining, devastating the habitats, and air pollution\u201d).<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\">\n<p>&#8220;They&#8217;re building bigger and bigger turbines that are cheaper and cheaper.&#8221;<\/p>\n<cite><em>Mark Z.

This releases a tremendous amount of energy in the form of heat, and that heat is used to boil water. Steam from the water then spins turbine blades connected to electric generators.<\/p>\n\n\n\n<p>Nuclear power is more consistent than solar or wind, and unlike the burning of fossil fuels, it does not generate greenhouse gas emissions, though it does create a <a href=\"https:\/\/www.freethink.com\/energy\/future-of-nuclear-power\">small amount of radioactive waste<\/a> that must be properly stored.&nbsp;<\/p>\n\n\n\n<p>The same process happens at a floating nuclear power plant (FNPP)\u2014the only difference is that the plant is smaller and built on a ship, barge, or other floating platform rather than on solid ground.<\/p>\n\n\n\n<p><strong>Current status:<\/strong> Russia\u2019s <a href=\"https:\/\/www.world-nuclear-news.org\/Articles\/Russia-connects-floating-plant-to-grid\">Akademik Lomonosov<\/a> is the only FNPP in the world.
