I really thought that an hybrid car was at least one order of magnitude more fuel efficient, but it's not the case.
I don't understand, because I thought buying a prius was an investment that you could repay in reduced gas bills, but apparently not so much.
Im quite happy to be able to live without a car.
Love it because my beloved Honda S2000 is one of the 4 examples under "sports car" :) Very neat project!
Hi there, We at BetaPeak ( https://betapeak.com ) are a small team of dedicated developers with passion for side projects and positive social change. We're located in Bulgaria, which currently has the worst air quality in all of Europe, so this led us to think - we sure as hell are not the only ones with that problem, there must be thousands of cities around the globe that breathe dirty air, we definitely need to rai…
Can't speak for all metric users, but I found "mt" for metric tonnes just confusing; the standard abbreviation is just "t". Yes, that's easily confused with the imperial ton, but I think that's a less important problem.
Other than that, neat!

The gas mileage seems off. I have a small SUV (Mazda CX3), and since there was no category for that (maybe the small SUV market is too USA-centric), I picked a "Medium car" (lke a VW Golf). But it gave the gas mileage as 18 mpg, while I get a measured 30 - 32mpg on my commute. Even when I had a golf, I was getting around 25 mpg.
The fuel consumption by vehicle category is based on averages. We didn't put too much energy into accurate measurements because you can change the consumption on the results page so that it exactly matches that of your car.

Mine too (55mpg average Skoda octavia which being much like a Passat is in their 'luxury' category). I'm guessing they make assumptions about the mix of electricity on the grid. Seeing as we are able to purchase green electricity here they should let us alter that assumption.
Yes, your assumption is correct, we actually account for the means of electricity production, as well as the car production process emissions related to building a single electric vehicle. It's a great idea to be able to switch those overhead emission calculations if you wanted to, we'll get on that!
"This is the emissions index of an electric car, given the average amount of emissions generated by the production of the electricity that powers it." Does this factor in locale? Because electricity generation in NZ is 80% renewable, and if we take the US generation ratio (I think something like 20% renewable), it paints a very wrong picture. If it does take into account locale, kudos!
We thought about that exact thing! However, we didn't have enough data to make this work. The numbers we display are averages. We'd love to make it more accurate once we have the resources!

I find it a bit scary that I should apparently keep with my diesel rather than look at electric. Should I really ?

getting even somewhat accurate values for that is a rather big problem, as you can't just take average emission values for a country as a base but rather need to look at the daily and weekly recharge distribution of different types of electric vehicles and then look at what the typical power generation structure is in those hours (which also varies seasonally). Its a huge project in itself and I think maybe you shoul…
Or is my '80% renewable' point naive? I think i get what you're saying, if I recharge during peak demand times, there's a chance nonrenewables are being used in higher proportions to fulfil my charge. Conversely if I charge during low-demand hours, the odds are higher that peak generation methods are not being employed.
But even more complicated than that, is the kind of renewables. NZ has a ton of hydro, and during certain times of the year they are drawn down for peak demand, so kinda ideal. Then again during times of drought, no can do and non-renewables may be the only thing that can meet demand.
If you're getting super fancy, NZ Transpower publishes live stats for the grid, including proportion of renewables in use at any one time! https://www.transpower.co.nz/power-system-live-data
