| > We have a billion power-hungry PCs running Let's do some math. According to [1] Human production of energy is even lower at an estimated 160,000 TW-hr for all of year 2019 (a COVID year) Let's hypothesize the difference is on average 10watt/hour (rather large for the average device), the difference for a billion devices would be 10GW/hour. Which is exactly 1/16,000,000th of the total. Assuming every Apple computer consumes 100watts less than the equivalent non Apple, assuming there are 20 million new low power Apple computers (probably there are much less), assuming the CPU are 100% of the time in sustained mode (of course on average CPU do not run at 100% of the power all the time continuously, but let's assume they all do in this example) it would mean 2GW/hour saved, which corresponds to a 1/80,000,000th of the total. It would allow, maybe, to shutdown an average power plant (the largest one produces 23GW/hour) Unfortunately there are over 65,000 power plants in the World, 2,500 of which run on coal. Unfortunately the energy saved could come from renewables, so the difference on emissions would be even less relevant than it already is. Economically those 2GW even at the Denmark prices ($0.50/KW) would cost one million dollars (2GW = 2,000,000KW). AKA nothing. As you can see the difference must be quite large to make a real measurable difference. [1] https://en.wikipedia.org/wiki/Earth%27s_energy_budget |
