At 270 watts, your graphics card is using less energy in a day than it takes to drive your 2k pound car down the street to buy a coffee at Starbucks.
A gallon of gas is ~33kWh. A mile is ~1kWh.
- Damogran6 5y agoLooking at what it takes to replace a gas fueled generator with solar, it's easy to overlook how much power is in gas. The one upside to permanent solar is that it's always producing when there's enough sun...unlike a generator that needs to be using fuel to make power.
- dahfizz 5y agoYeah, gasoline is incredibly energy dense. Unfortunately, internal combustion engines are also really inefficient. The Tesla battery pack weighs over 1000lbs, but only carries the same energy as 3 gallons of gas.
- CyanLite2 5y agoYou're probably off by an order of magnitude. But your point is valid nonetheless. Average Tesla can do nearly 300 miles per charge. A gallon of gas can do about 30 miles per gallon in a similar sedan.
- svnt 5y agoIf you did some more math instead of assuming you were right you would see that their numbers are actually right, and so are yours.
- inglor_cz 5y agoHe is right. Electromotors are way more efficient than ICEs. That is why many of the world's railways run on electricity, at least on the main lines: it costs something to set up all the catenary wires etc., but the operational savings are huge.
- dahfizz 5y agoWhat am I wrong about? A Tesla gets ~130 mpg equivalent [1]. This means that if you put a gallon of gas worth of electricity into a tesla, the Tesla can go 130 miles. On that same page you can see the Tesla is rated for ~350 miles of range. So the Tesla battery pack carries less energy than 3 gallons of gas. Let's phrase it this way: if you had a 100% efficient generator, you would need less than 3 gallons of gas to fully charge a 1000lb Tesla battery pack. The Tesla could then travel 350 miles with that energy. [1] https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=43401 https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=43401
- onlyrealcuzzo 5y agoI think it's easier to say: A Tesla long range battery is 82 kWh. A gallon of gas is ~33.7 kWh. So even in a Tesla, 1 mile of driving = 1 hour of gaming = it's not worth talking about gaming as a cause of global warming.
