The United States now spends 60 percent less energy for every dollar of GDP than it did in 1950. Europe is half as much. China, which in 1990 consumed four times as much energy per dollar of GDP as the world as a whole, by 2012 had reduced costs to half of the global average.

Globally, the trend is the same: we spend 25% less money on electricity than we did in 1990. By the way, before the collapse of the USSR produced a huge amount of energy, but it was useless - everything was sold, not consumed. And we - and you - are obliged to consume it.

In addition to the desire to save energy, an important factor was the fact that we learned how to store energy in very small batteries, the capacity of which per unit weight was unimaginable even 20 years ago. For example, Motorola's first cell phone, which went on sale in 1984, had a nickel-cadmium battery weighing almost a kilogram, and worked in talk mode for 35 minutes, after which it required a 10-hour charge. Recently, British scientists have gone further and discovered how to increase the power capacity of lithium-ion batteries by another 1.5 times. Now flexible batteries are appearing, which is hightech in general. For example, you can stick a battery in places where the sun never shines and not fear the laughter of the surgeon on duty.
