What make of EV do you own? At least cyclist admits he doesn’t own one and won’t own one. Kinda makes you wonder don’t it?😂 Oh I will some day. When the biodiesel thing goes away. Genuinely curious as to the answers here: Biodiesel is burned in your engine and then you emit exhaust, I would presume. What is that exhaust comprised of? I would think carbon is a significant component. Is that not the case? How does this exhaust differ from that of a fossil fuel powered engine, other than one gives people the munchies while the other does not?

In all seriousness, does the greater weight of an EV than for a similar size gas guzzler, result in faster tire wear? Does the weight of an EV require a different tire compound? Road wear rate is generally based on the weight of the vehicles using the road, so tire wear should follow the same principle.

Fossil fuels are permanently sequestered carbon sources whereas biodiesel is from a renewable resource that cycles carbon.

What percentage of biodiesel is actually from cooking oils? I don’t know that is why I am asking?

We all know where fossil fuels and biofuels come from. The question was about what the difference is in the emissions. Still interested in your answer, if you care to give it.

You asked about carbon, its carbon neutral, but there are still tailpipe emissions, no2s and particulates.

Really I asked about the emissions and simply indicated that I assumed carbon was one of the components.
So from a cleaning up the atmosphere perspective, it would be neutral then when compared to traditional diesel?
I get the renewable aspect. So is ethanol, though it’s less efficient and takes fuel to produce it, which further reduces its efficiency.

It takes fuel to produce biodiesel Biodiesel is produced from vegetable oils, yellow grease, used cooking oils, or animal fats. The fuel is produced by transesterification—a process that converts fats and oils into biodiesel and glycerin (a coproduct). Approximately 100 pounds of oil or fat are reacted with 10 pounds of a short-chain alcohol (usually methanol) in the presence of a catalyst (usually sodium hydroxide [NaOH] or potassium hydroxide [KOH]) to form 100 pounds of biodiesel and 10 pounds of glycerin (or glycerol). Glycerin, a coproduct, is a sugar commonly used in the manufacture of pharmaceuticals and cosmetics. afdc.energy.gov/fuels/biodiesel-production#:~:text=Biodiesel%20is%20produced%20from%20vegetable,and%20glycerin%20(a%20coproduct).

No such thing as fossil fuel.

No such thing as fossil fuel. Yes there is.

Plant goo, at least most of the time, you are not pouring refined dinosaur parts into the gas tank of your vehicle.

We call crude oil and petroleum fossil fuels because they are mixtures of hydrocarbons that formed from the remains of animals and plants (diatoms) that lived millions of years ago in a marine environment before dinosaurs existed. Over millions of years, the remains of these animals and plants were covered by layers of sand, silt, and rock. Heat and pressure from these layers turned the remains into what we now call crude oil or petroleum. The word petroleum means rock oil or oil from the earth. www.eia.gov/energyexplained/oil-and-petroleum-products/#:~:text=We%20call%20crude%20oil%20and,marine%20environment%20before%20dinosaurs%20existed.

They fail to mention how much “Fossil Fuels “ it takes to produce these biofuels. I hauled a load(6200 gallons) of used cooking oil from Ocala to Houston to a refinery. I happened to burn diesel fuel in my truck. 😉

True cost fight only counts towards the negative when it's something Cyclist doesn't like.
