I do believe electric cars can be better, and particularly on the cleaner grids, but introducing a made up fudge factor for political reasons is a bad idea, because p. Another way you might want to compare your kwh and your gallons would be by the pollution emitted. Significant amounts of oil are imported, sometimes from unfriendly areas. Quite commonly people will say they just plan to run their electric car on solar and thus have no pollution at all. See full list on ideas.4brad.com
Lots more research is being done on calculating grams of co2 (or equivalent) per mile as a way to compare electricity and gasoline.
We are working on making electrical generation cleaner. On the other hand it is debatable. That's pretty good and about 85 miles for the cost of a $3 gallon of gasoline. I refer you to my earlier post and the linked flash applicationto see details of your own local power grid. Problem is, had the epa used that number, it was more than double the perfect energy conversion number and it would have looked reallyridiculous. This also is highly locally variable, with very high numbers in the coal states and nice numbers in the hydro and nuclear powered areas. You'll see in their math that they want to use the heat formula (real energy used) but then they have to multiply it by something called the fuel content factor. it's amusing to read how they describe it, it's effectively a constant pulled out of thin air because politically they wanted to make alternative fuel vehicles look better. If global warming is your big issue, this is the one hat you'll focus on. The jury is still out on the cost of the battery as an expendable part of the car. Older electric vehicles have energy efficiencies of about 2 miles per kwh. Jun 29, 2018 · for example, a typical electric oven consumes about 2.3kwh of electricity, while a typical gas oven will use approximately 12mj per hour. 45 minutes per load, electric model uses 3.3 kwh, gas model uses 0.22 therm + 0.21 kwh. Gallon of gasoline contains 114,000 btus of energy, or about 120 million joules.
Indeed this isprobably the main thing in people's minds, since nobody is buying electric cars to save money right now, though theymight in the future. Electricity is cheaper than gasoline, no doubt. The jury is still out on the cost of the battery as an expendable part of the car. Some worry the batteries need replacement at a. Lots more research is being done on calculating grams of co2 (or equivalent) per mile as a way to compare electricity and gasoline.
This method is also pure in that it deals with the real energy being released, either by burning gasoline, or coal, or natural gas, or burning nuclear fuel.
Mainly we generate heat from the chemical energy of the fuels, and turn that heat to electricity. Some worry the batteries need replacement at a. As in all total cost well to wheels. In the past, these rates have ranged from 3 cents to as high as 50 cents per kwh. Panels not connected to the grid instead handle live loads or charge batte. Fuels for electricity are almost entirely domestic. Gas model asumes rate in the electric column to spin the drum. A fair criticism, however, is who cares about the heat released. I've also seen credible arguments that due to the fact that about 1.5% of the natural gas pumped in the usa leaks into the air, and that methane is anywhere from 80 times (20 year average) to 20 times (100 year average) more potent a ghg than co2 is, the figure for natural gas generation should be higher, more like 700g. At present, nuclear power and hydro don't emit much pollution at all, but people are very divided on how green they are. Indeed this isprobably the main thing in people's minds, since nobody is buying electric cars to save money right now, though theymight in the future. Hydro and natural gas can be turned on and off quickly and thus tend to be used for peak load. However, for a while before the cars came out, nissan did tout numbers in this region, and so have other electric car makers.
I've explained this before but it's worth adding again here. The doe method says a kwh at the plug takes 10,300 btus, not the 3400 of perfect conversion. Where there is nuclear, it will tend to that as nuclear plans don't shut down easily. Don't forget that the usa has the dirtiest power grid in the western world nowadays. A fair criticism, however, is who cares about the heat released.
Electric ranges are a lot more efficient than gas, but gas is very cheap, so overall it's usually cheaper to use gas even though it's not as efficient as electric.

Lots more research is being done on calculating grams of co2 (or equivalent) per mile as a way to compare electricity and gasoline. Hydro and natural gas can be turned on and off quickly and thus tend to be used for peak load. While we're all about ghg today, the reality is that gasoline and coal emit a lot of pollution of other forms. Electric heating cost is much cheaper. Quite commonly people will say they just plan to run their electric car on solar and thus have no pollution at all. See full list on ideas.4brad.com At perfect conversion, you get about 36 kwh in a gallon of. What that is varies from place to place. Which is cheaper to run electric or gas heating? The price of electricity also varies locally. Where there is nuclear, it will tend to that as nuclear plans don't shut down easily.
Gas Vs Electricity Kwh - Is Gas Or Electricity Cheaper Compare The Market - They are about 30% of us power production, and much more of power in europe and.. To properly meet green goals, solar panels mustbe connected to the power grid. The department of energy studies all the power plants in the usa, and their efficiency is calculated and averaged. There are, alas, many ways to look at pollution. Mainly we generate heat from the chemical energy of the fuels, and turn that heat to electricity. You can refresh your carnot knowledge for more on the limits of this, but the reality is that our power plants extract about 30 to 50% of the chemical energy, first into mechanical energy (spinning turbines) and then into electricity.
