These turbines are NOT the future. There was 11% less wind energy produced in 2016 compared to 2015. Why, you might ask? Because the year was less windy. What do you think happens then? Yes. Coal plants. Nuclear can give us safe, reliable energy. In the entire process from making the plant until it needs to be deconstructed as it's gotten too old, a nuclear power plant has the second lowest carbon footprint out of any current methods of generating power. The only one that is lower, is hydro power. Hydro power, however, causes the collapse of entire ecosystems. Nuclear is the only source of energy of which all harmful matter is contained and only water vapor enters the atmosphere. 95% of nuclear waste of uranium fission is also less radioactive than your average slab of granite and the other 5% can be stored safely underground until we find a better solution for it in the future (for example, we transport nuclear waste by truck and train nowadays. Trains and trucks had times when they were super unreliable. In the future, space travel will be much safer and we can simply throw out the radioactive trash into space.).

[@jackfenn7524]

So Betz came up with a plan to ignore physics and common sense? You want to show how well these "wind turbines" work? Put one up, and keep it on the internet all the time. Demonstrate how much electricity it makes. Now put up a much smaller and cheaper wind-mill which generates electricity. The con-job would instantly become apparent. Windmills work very well. Wind turbines don't work at all.

[@jeremyoverby2523]

They are hooked up the "internet" 24/7. It's known at SCADA- supervisory control and data acquisition. It's a live condition monitoring software. The wind turbines work very well. Betz limit is the theoretical limit of how much energy you can extract from the wind before the wind flow is slowed down and the wind nearly stops.

Great video. It would have been great if it continued and explained how the electricity is stored and utilized for power. Well explained and informative. Thanks.

[@iareid8255]

nssm, electricity is not stored in a grid system, demand and supply is always balanced within close limits. Some utilities and others use spare generating capacity to store potential energy. A common one is hydro pumped storage. This is a system with two dams, upper and lower. The upper dam is filled by pumping from the lower dam when grid demand is low. It consumes more power than it generates. It's function is to quickly generate power for the grid when there are sharp peaks in demand, as they start generating just by opening a valve which starts the turbine. (The turbine and the pump are one and the same machine, i.e. dual purpose). Solid state batteries can do teh same, but note they are not storing power to use later, it is the rapid response to peaks that is why they are used. It gives some time to theconventional generators to pick up the load, this is only a matter of minutes or less. The grid (U.K.) runs at 50 Hz within+ or - 0.5 Hz, increased grid load pulls therequency down, just like a car meeting a hil, you open the throttle maintain speed, generators do the same, their fuel supply is opened automatically by the governor. If the limits are exceeded then switches disconnect part of the grid and a power cut occurs. Wind generators, by the way contribute nothing to this continuing and regular load balancing.

👍 Thanks. Great very well explained

[@GururajBN]

Very insightful video. I didn’t know that the blade direction could be altered. That’s a useful feature. At 59% max efficiency, this is better than thermal power which usually provides 45% efficiency. I have two questions: how long do the wind mills last, and what is the nominal power output of a windmill.

[@F1ve-seveN]

Nah Good hydrogen-combustion thermal power generator can achieve 55% - 65% efficiency on a 1M - 1.5M scale already. It's just that hydrogen-based generator can't be vastly deplayed due to the lack of natural hydrogen resources.

[@F1ve-seveN]

Also Most of the turbine now can't even achieve 40% efficiency consistently. While thermal based generator can keep at up to 45% very consistently. There's still a long way to go for wind turbines.

Thanks for the nice video. In theory would installing multiple turbines in a known windy area (e.g. gaps between buildings where wind is forced to squeeze through) slow down the winds and also generate more power than a single turbine?

[@Gabrie177]

I finally learned how wind turbines work. Cuz I always wondered about the speed of wind and how power can generate when the wind speeds are at a minimum

[@shepherdwarriorKING]

The wind passes over the blades and makes them turn (kinetic energy) the blades turn a shaft within the nacelle(the box at the top of the turbine).The shaft turns a generator which converts the kinetic energy into electical energy. A step up transformer converts the electricity to a higher voltage to be transmited (electrical transmission) ; Typically to 11,000V up to 33,000V and The electricity is then exported to the local electricity grid network.

[@nmahendrareddy4025]

[@Sephirithe]

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

[@googoogiggle6775]

This is is kinetic energy ://kzbin.info/www/bejne/rZfdmHyugqqibsk

[@jackfenn7524]

And once that small amount of electricity is "on the grid", it is quickly lost due to resistance in pushing it down a power line. If that electricity were used at the source where it was produced, small factories would soon produce a profit from that renewable electricity, and selling of the products made would be applied to your power bill, making your home electrical bill much smaller.
