[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Because electricity to my home for lights and refrigerators is more important than your sitting in traffic with your Tesla. I mean transportation is important, but when push comes to shove, there is so much wasted energy running around that people can easily prioritize. But plugging in that EV sends energy bills through the roof.[/quote] Really when I plug in my EV I get the equivalent of a tank of gas for $15. A friend said they spent $85 on a tank of gas today. You also do not seem to understand how EVs works. Sit in traffic does not waste energy in an EV. EVs are 95% efficient vs a gas car that wastes 2/3 of the energy in a gallon of gas due to thermal loss. [/quote] I’ll admit to knowing nothing about how cars work beyond “this pedal makes it go,” but that claim seemed sketchy to me too. We have one gas-powered car and just got one EV, and we do almost all our driving in heavy DC traffic. The gas car has great MPG on the highway but terrible in the city because of how much it burns through when sitting at lights or otherwise in heavy traffic. We have to ignore the “25 miles left” type countdown when the gas tank gets low because even though it automatically adjusts for highway vs city, it doesn’t adjust enough and drops precipitously on the 2-mile round trip to school dropoff. Meanwhile when the EV isn’t actively driving, it just powers down and waits. Since I’m weighing in, though, I will say that owning an EV in DC without the option of home charging has been a bigger headache than we expected. The charging infrastructure just isn’t there, so what IS there is always taken. It has been a constant battle, and I don’t think we’ve made it all the way to a full “tank” a single time in the month that we’ve had the car. DC announced a pilot program for curbside chargers, and even that is both some point in the future and ONE unit per ward, so I don’t anticipate this getting much better any time soon.[/quote] Here you go. [quote] U.S. residents are collectively burning about 8.9 million barrels of gasoline a day, or a little over one gallon each for every person in the country. That enormous sum has decreased by around 5% from the nation’s peak gasoline use in 2018. Today’s gasoline-fueled cars and trucks waste around 80% of the energy that gets pumped into their gas tanks. A car heats up as it burns fuel to move pistons and propel the wheels. The heat is not needed to move the car, so it is vented off, carrying away most of the energy in the fuel. This isn’t necessarily a design flaw; it’s an inevitable part of thermodynamics. Burning fuel to create motion tends to be an energy-wasting proposition. Electric vehicles operate with only around 11% energy loss, meaning that most of the energy that goes into the car ends up turning the wheels. Because the vehicle doesn’t burn fuel, there is no thermodynamic penalty for converting heat to motion. Also, EVs can recapture energy during braking, boosting overall efficiency.[/quote] https://yaleclimateconnections.org/2024/01/electric-vehicles-use-half-the-energy-of-gas-powered-vehicles/#:~:text=Today's%20gasoline%2Dfueled%20cars%20and,be%20an%20energy%2Dwasting%20proposition. Let’s say your gas car gets 20 mile per gallon. The total potential energy in a gallon of gas if used at 100 efficiency by your car would give you 100 miles per gallon. This applies to all fossil fuel- coal, natural gas, etc. [/quote]
