You guys need to do a little studying up on Watts and Vars, seriously, you are being misled. Watts you pay for, Vars you don't. Watts do the work in motors, heaters, etc. Vars do magnetization, period, to allow the motor to rotate. Vars do require current, but don't require fuel, other than to cover small heat losses.
That video hooked up a grossly exaggerated inductive load to a line with a power factor of about 0.35, typical is a much higher 0.85 or better, so of course the amps shows high. Then they hook up a simple capacitor bank (aka - vars in a power system) to increase that power factor and reduce amps. There's not one thing magical or innovative about it, studied it my sophomore year in 1979 on my way to a BSEE.
Yes, the amps required to make vars do cause heat and line losses mentioned previously, but those losses are about 4% in typical transmission systems, with another 4 - 6% for your local utilities hook up to your house. If a customer had such an inductive load that the power factor is less than 0.85, their utility might tell them to hook up a capacitor bank, might not, might put one nearby themselves, really depends on whether saving 15% of that 10% max losses (1.5% of the load to that customer) is worth chasing. But it isn't new, isn't innovative, and has been done. Utilities are very well aware of techniques to reduce losses when it pays to do so.
No wonder comments are prohibited on that video.
