The world’s largest offshore wind farm is taking shape off the east coast of Britain, a landmark project that demonstrates one way to combat climate change at scale. Located 120 kilometers (75 miles) off England’s Yorkshire coast, Hornsea One will produce enough energy to supply 1 million UK homes with clean electricity when it is completed in 2020.
The project spans an area that’s bigger than the Maldives or Malta, and is located farther out to sea than any other wind farm. It consists of 174 seven-megawatt wind turbines, with towers that are each nearly 100 meters tall. The blades cover an area bigger than the London Eye observation wheel as they turn.Just a single rotation of one of the turbines can power the average home for an entire day, according to Stefan Hoonings, senior project manager at Orsted (DOGEF), the Danish energy company that built the farm.Content By BPAmerica’s role in the dual energy challenge will influence the entire world.
As the second-largest consumer of energy in the world, America’s handling of the dual energy challenge will set the tone globally.The project will take the United Kingdom closer to hitting its target of deriving a third of the country’s electricity from offshore wind by 2030.
It’s the kind of project that can help governments achieve environmental targets set out at this week’s United Nations Climate Action Summit in New York. Some 77 countries committed at the summit to cut greenhouse gas emissions to net zero by 2050, but climate activists including Greta Thunberg say that major emitters must do more to mitigate rising temperatures.
The Hornsea One proejct will produce enough energy to power up to 1 million UK homes.Renewable energy will be critical to achieving thoseclimate goals.Despite the commitments made as part of the 2015 Paris climate agreement, global emissions continued to rise in 2018, and global energy demand grew at its fastest pace in a decade, according to the International Energy Agency.
Coal use in power generation accounted for a third of total CO2 emissions, the IEA said. The trends demonstrate the need for additional clean energy solutions. In Britain, three more phases of the Hornsea project are planned.
The share of renewables in the global energy mix is small but growing. Eventually a tipping point may be reached. After 2035, renewables are projected to make up more than 50% of generation, according to McKinsey. Wind power is a big part of the solution. According to the IEA, electricity generation from wind grew by an estimated 12% in 2018, keeping its position as the largest renewable technology that doesn’t involve water.
The company behind Hornsea
Orsted has built 25 offshore wind farms across Europe, the United States and Asia. It changed its name from Danish Oil and Natural Gas in 2017 to reflect its transformation to a green energy company. The company has cut its use of coal by 73% since 2006 and plans to be coal free by 2023. America’s top energy regulator agonizes over the downfall of coal country.
The United Kingdom is its biggest market for offshore wind and Orsted will have invested £12 billion ($15 billion) in the sector by 2020. With a capacity of 1.2 gigawatts, Hornsea One will generate nearly twice the power of Orsted’s Walney Extension — the current largest offshore wind farm in the world, located in the Irish Sea.
