Ming Yang Wind Power Group Limited ("MingYang", 明阳风电) is the largest private wind turbine manufacturer in China. They have a Youtube channel (420 subscribers). I got one-shotted by this video (156 views). It's ABSURDLY Chinese, on multiple levels. now you have to watch it too

Must watch explanation on clean energy by Greg Jackson on #BBCQT - also watch Tim Stanley squirm repeatedly when Jackson gives answers Greg Jackson, "We've crossed the rubicon.. Clean energy is now cheaper than fossil fuels" "Power from wind and solar is cheaper than power from fossil fuels" "Consumers don't see the benefits because our markets are run in the old traditional way" "We need market reform so when we build wind farms, people get cheaper energy" "It doesn't help that we are paying wind farms to turn off when it's windy, instead of giving people cheap power at those times" "59% of all of the renewable energy has been built in China" Fiona Bruce, "They're also building huge coal plants" Greg Jackson, "The majority will never be used, they'll be mothballed" "Why are they building green energy? It's not because they're nice people. Now they recognise clean energy is cheaper, and energy is the engine of growth for their industry, they're investing in it" "Six or seven years ago if you went to Chinese cities people wore face mask because of air pollution.. That's gone" Tim Stanley, "If you have a period where the wind dies and the sun doesn't shine, what happens, you have to rely on back up.. Rely on gas.. Import the power from overseas" Greg Jackson, "Allow me to help you with this answer.. As somebody who buys more power than anybody in the UK.. I can give you an authoritative answer on what to do" "An electric car holds enough power in its battery for a typical house in the best part of the week" "As more and more electric cars hit our roads, we have distributed storage of electricity, days on end, without wind" "It's not the whole solution but it's a big part of it.. And it helps us reduce our reliance on things like those fossil fuel backups" "It's always windy somewhere, it's always sunny somewhere.. As we connect our country to others.. When they're windy we get their power, when we're windy we sell ours to them" "By the way, we are one of the windiest places in the world.. This is a huge export opportunity for the UK"

A modern wind turbine looks deceptively simple from the outside. The largest onshore turbines now use blades stretching beyond 80 metres, sweeping more than 20,000 m² of air. Yet the entire structure rotates at only around 10-20 RPM. Actually, inside the nacelle is a precision gearbox that transforms this slow, high-torque rotation into the 1,000-1,800 RPM required by the generator. This gearbox is one of the most demanding mechanical systems in renewable energy. It continuously transmits megawatts of power, while surviving changing wind loads, vibration and billions of fatigue cycles over a 20-25 year lifespan. Inside are planetary gear stages, precision-ground alloy steel gears, advanced bearings, lubrication systems and cooling circuits. Some of the largest geared turbines contain close to 1000+ liters of specialised synthetic oil to manage lubrication and heat during continuous operation. A single large onshore turbine can cost around $4-5 million, with complete projects costing significantly more after foundations, roads, electrical systems and installation. The goal is for the machine to recover its capital cost within roughly 5-10 years, then continue producing electricity for decades. This is why reliability is the biggest challenge. Gearboxes, bearings, generators and electrical systems remain critical failure points, pushing engineers toward better materials, sensors and predictive maintenance. The scale of this industry is enormous. China has become the world’s largest wind turbine manufacturing and exporting hub, with several Chinese companies among the largest turbine suppliers globally. Building a wind turbine is not just about capturing wind in an efficient manner, It is about creating a machine that can convert wind energy into electricity for millions of hours with minimal human intervention and sustain millions of load cycles.
