General Electric has announced that it has begun work on building and testing the world’s most powerful wind turbine, which will be a true revolution in the world of renewable energy technology.
Not long ago, the Danes boasted about their world’s most efficient 9 MW wind turbine called the V164 from MHI Vestas Offshore Wind, which weighs 1,300 tons, measures 220 meters tall and has 80-meter blades (one blade weighs 38 tons).
However, General Electric has built an even larger and more efficient turbine. Haliade-X will have a capacity of 12 MW and produce 67 GWh of electricity per year. Just one such turbine will supply at least 16,000 homes with electricity. Haliade-X is 260 meters high and its three blades are 107 meters long each.
Americans haven’t said their last word yet. GE engineers are working on an even more powerful wind turbine, which is expected to come into use in the coming decade. According to the revealed information, the turbine is to be adapted for installation at sea and will measure 480 meters in height, which is taller than the second tallest skyscraper in New York.
The device producing electricity, thanks to the power of wind, is to have the capacity of 50 MW and generate 268 GWh of electricity per year. As in Poland we consume approximately 170 TWh of electricity annually, it means that theoretically only 650 such offshore turbines can meet the energy needs of the whole country.
A farm with 650 turbines may seem like a huge undertaking, but when viewed from the perspective of Western countries, where farms with 100 to 200 turbines are currently being commissioned, building several farms in the Baltic Sea will not be such an unattainable plan. It should be noted that according to the draft National Energy Policy, in 2040 such investments in Poland will surpass the global pioneer of offshore wind farms, i.e. Denmark.
The government wants to build as many as 1000 wind turbines in the Baltic Sea within the next two decades. The total capacity of the installations is to reach 10.3 GW. It is worth pointing out that Germany, one of the richest countries in the world, wants to have 15 GW of offshore capacity by 2030, so the ambitions of a much poorer country like Poland are admirable. The EU authorities plan that by 2030 RES will constitute 32 percent of all energy produced in the Community.
If the development of technologies for obtaining energy from renewable sources continues at such a rapid pace, we can expect that in 20 years the majority of homes in the lion’s share of the world’s countries will have green energy flowing from their sockets, and the environment of our planet will breathe a sigh of relief.
