How much energy is needed to run a car? Google News
The energy density of the energy we use depends on how much we burn it, but how much is the energy that’s needed to operate a car or truck?
If you’re wondering how much energy you need to power a car, a recent study from researchers at the University of Michigan and the University at Buffalo has the answer.
The study is the latest attempt to answer that question and it may lead to better fuel economy standards.
It looked at the energy used by 1,200 drivers over a 30-day period in 2016 and found that a gallon of gasoline requires 1.7 kilowatt-hours (kWh) of energy.
A gallon of diesel uses 5.2 kWh, and a gallon-and-a-half of natural gas uses 10.8 kWh.
That’s not all.
You’ll also need about 4,000 gallons of ethanol to fuel a truck.
The fuel efficiency of a truck is also pretty good, with the average efficiency rating of 84.9 percent.
The researchers found that the energy needed to drive a truck has a large effect on fuel economy.
“What we found is that drivers’ energy demands are higher than what we thought,” said Andrew C. Mott, the study’s lead author and a professor in the Department of Electrical and Computer Engineering at Michigan.
“They are actually significantly higher than the energy density, which we would expect to be lower.”
The study did find some differences in the amount of energy used, which may be attributable to differences in vehicle weight, engine size, and fuel efficiency.
However, the researchers noted that these differences are small compared to the energy required to operate vehicles.
“The study shows that there is significant variation in the energy usage for different types of vehicles and that we need to consider that in future studies,” Mott said.
“It is important to note that the data are not an indication of energy efficiency, and the findings may be more reflective of fuel economy.”
He noted that, because the study is based on vehicles, it does not include vehicles in the real world.
“We think that it is very unlikely that we can estimate the energy efficiency of the world’s vehicles,” Mampitt said.
The data for the study comes from the 2016 National Household Energy Survey, which surveyed about 9,500 drivers.
The survey is a monthly survey that looks at the amount people use of energy for various activities and uses the results to create a detailed profile of the consumer.
Mampatt said that the study has a few limitations.
The drivers were asked questions about their daily energy usage during the study.
The questions asked about the number of miles driven, fuel economy, and how much gas they used.
It’s not clear how many people had to drive more than a certain distance to get to a particular location.
Mowatt said the study does not take into account how much time people spent doing various activities, which could affect the energy consumption.
“Our study is very preliminary, so we have no way of knowing how well it will translate to real-world energy consumption,” Mowitt said, adding that the researchers are working to refine the methodology.
For instance, it’s possible that a person could drive to work and then drive to a grocery store or a movie theater and then stop to rest.
That would reduce their fuel use and decrease their energy consumption, he said.
Still, Mowtt noted that he’s optimistic about the findings.
“These results should lead to improved fuel economy and more efficient vehicles,” he said, noting that the fuel economy data is based solely on fuel consumption in a vehicle and doesn’t take into consideration other factors like the amount or number of occupants in the vehicle.
“If we can do a better job of analyzing the fuel efficiency and energy use of cars, then we’ll be able to improve fuel economy as well,” Mamps said.
For now, Mampett and his colleagues are still working to make the data more detailed.
“There are a lot of assumptions we have made,” Mumps said.
But they’re hoping that the findings will eventually lead to more meaningful fuel economy statistics.
“That’s a very exciting direction,” Mowell said.
Mamps and Mott hope the results will encourage manufacturers to produce more fuel-efficient vehicles.
That, in turn, could reduce energy costs for consumers and encourage automakers to put more energy-efficient cars on the road.
