this is physically impossible. You can't have more demand in terms of kw-h, joules, amps, watts or whatever yet also not have more demand. The device could have 0.0001% efficiency or 99.99%. If demand goes up, demand goes up. What the device does with that power is not relevant.

You can have a demand for more lumens of lighting power... but if you previously used incandescent bulbs and now go for LED, you can expend less electrical energy than you did with the old bulbs.
- gibolt 2y agoImagine the increase in demand without the efficiency improvements. Improving everything that pulls power significantly decreases the growth curve, meaning more time to increase available capacity.
- quickthrowman 2y agoAn LED lamp puts out more lumens per watt than a fluorescent or incandescent lamp. Similarly, an induction motor controlled by a variable frequency drive can use much less energy by varying its speed instead of using a fixed speed motor starter. VFDs typically get signals from building automation or process control systems and adjust the motor speed accordingly. An arbitrary example would be a fan running at 50% speed generating 50% airflow but using only 25% of the electricity needed to run at 100%. https://www.energy.gov/eere/amo/articles/adjustable-speed-drive-part-load-efficiency https://www.energy.gov/eere/amo/articles/adjustable-speed-dr...
