The upcoming 12 megawatt wind power platform will be almost three times the height of the Statue of Liberty.
Currently being developed by General Electric, the gigantic turbine is due to be tested at a facility in Northumberland, England as part a new five-year agreement with the British government.
Known as the Haliade-X 12 megawatt (MW) turbine, the wind platform is set to help the UK become a leader in offshore wind technology with up to 30 gigawatts being generated by 2030.
"This is an important agreement because it will enable us to prove Haliade-X in a faster way by putting it under controlled and extreme conditions," said John Lavelle, CEO of GE's Offshore Wind business.
With a rotor measuring 220 meters across, the new turbine will certainly be difficult to miss.
He does have a point, a lot of these alternative energy ideas are more feel good projects then actually beneficial projects. Wind turbines are at best only 69% efficient, there is just no way to get past the Beltz limit. Then there is the issue that wind blows at different speeds, if it blows to slow the turbine produces no energy, too fast and the blades cut out to prevent damage also producing no energy. Realistically it is very rare for a wind turbine to operate at 100% of its capacity, if I remember correctly if everything is done right the wind turbine will average out at about 60%. ... [More]
No energy conversion process is very efficient. Be it solar cells, internal combustion (IC) engine, wind turbine, hydro-electric scheme, whatever, the conversion rate is low. Some are better than others. The efficiency of a wind-turbine is higher than that of the IC engine. The overall efficiency of the IC engine in extracting energy from fossil (hydro-carbon) fuels is 25% or less, much lower than a wind turbine or a solar panel. Making people feel good has nothing to do with. There are sound engineering and thermodynamic reasons for pursuing renewable and alternative green energy technologie... [More]
There are no truly sound engineering or thermodynamic reasons for pursuing renewable and alternative green energy in it's current form other then to feel good. Of course some energy conversions are better then others but the renewable/green ones are specially bad. You mention the internal combustion engine, which do have very bad efficiency, luckily internal combustion engines arent used to generate energy. The boilers used by coal and natural gas power plants are on average 85% efficient. Wind on the other hand for example has the beltz limit which by default limit it to 69% efficienc... [More]
Good to show that 57.8% of Germany's electricity production, which is different then energy consumption, is still coming from coal, natural gas, and nuclear so far this year. We gone over this before but if we need to I can go over this all again later tonight where I show you once again that all of Germany's green/renewable engery production have hit hard walls and are not going to be expanding significantly any time soon.
I have posted this before, but it pretty much sums it up: Of course there are issues with things like wind and solar energy, but they are being solved by people who don't just sit back and say " We need more coal". Cars and planes were pretty useless in the beginning, but we didn't just say "lets stick to horses as we have allways done".
The trend is doing the trick here. Currently 42,2% are coming from renewable energy sources, compared to 38,2% in 2017, 33,7% in 2016 and 33,5% in 2015 and ca. 25% in 2013. And, in 2022 the last one of initial 19 German nuclear power plants will be switched off forever. The German project is named Energy transition (and currently we are ahead the schedule) with the targets to generate energy from renewable sources at 50%/2030, 65%/2040 and 80%/2050; to reduce carbon emission by 40%/2020, 55%/2040 and 80-95% until 2050 based on the values of 1990.
A good place to start I guess would be with understanding terms, cause you keep using them incorrectly. The site you linked to, and love to use, shows electricity production. Electricity production does not equal energy production, electricity production is a part of energy production being approximately a third but far from being the entirety of energy production. Sadly that data only goes back to 2015 and being only partially through 2018 it does give a rather limited amount of data, but it does mean less typing. As for electricity production, in 2015 183.73 TWh came from renewable eng... [More]
