Electric vehicles vs gasoline vehicles

In summary, electric vehicles are more efficient than gasoline vehicles, with electric vehicles using 800,000 joules per mile on average compared to 3.3 million joules per mile for gas vehicles. However, when factoring in the energy required to go up a 15 degree incline with a total rise in elevation of 600 feet and a weight of 3,000 pounds, both vehicles will likely have similar energy usage ratios. The use of different fuels and taxation also plays a role in the overall cost of transport. When comparing electric and chemical propulsion, it is important to consider the entire energy chain, as it may or may not affect the performance comparison.

Will an electric vehicle use less joules going up a hill than a gasoline vehicle, because electric vehicles are more efficient? I've read that electric vehicles use on average 800,000 joules per mile, while gas vehicles use 3.3 million joules per mile. Assuming those numbers are based on horizontal tests, I'm wondering how many joules each would use going up a 15 degree incline, for a total rise in elevation of 600 feet, and both vehicles weigh 3,000 pounds.

Look up the efficiency of gas vs electric motors, then apply that to the physical energy required to "lift" a car 600ft.

Will probably come close to your numbers, or at least the ratio.

The whole field of transport costs is affected by Tax as much as basic efficiency.The secret of cheap transport is to use a fuel that is not taxed. Of course, you may need to produce a special engine to utilise that fuel. Life is never simple.

When comparing electric and chemical propulsion, it may or may not be relevant to compare the performance of the whole energy chain, rather than just to compare the energy supplied 'to' the vehicle, depending on what answer you want to get.
 

What is the difference between electric vehicles and gasoline vehicles?

The main difference between electric vehicles and gasoline vehicles is the source of energy they use. Electric vehicles use electricity stored in batteries to power an electric motor, while gasoline vehicles use gasoline or diesel fuel to power an internal combustion engine.

Are electric vehicles more environmentally friendly than gasoline vehicles?

Yes, electric vehicles are more environmentally friendly than gasoline vehicles. This is because they produce zero emissions from the vehicle itself, while gasoline vehicles emit harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter.

What is the driving range of electric vehicles compared to gasoline vehicles?

The driving range of electric vehicles varies depending on the model and battery size. However, on average, electric vehicles have a shorter driving range compared to gasoline vehicles. This is because electric vehicles rely on batteries that need to be charged, while gasoline vehicles can be refueled quickly and easily.

Are electric vehicles more expensive than gasoline vehicles?

In general, electric vehicles tend to be more expensive upfront compared to gasoline vehicles. However, they have lower operating costs due to the lower cost of electricity compared to gasoline. Additionally, there are government incentives and tax credits available for purchasing electric vehicles that can help offset the initial cost.

Can electric vehicles be charged at home?

Yes, electric vehicles can be charged at home using a standard electrical outlet. However, it is recommended to install a home charging station for faster and more efficient charging. Many electric vehicle owners also have the option to charge their vehicles at public charging stations, which are becoming more widely available.
