Toyota makes hybrids, they outsell all other hybrid manufacturers, and middle-america "doesn't want" electric vehicles while also demonstrating they don't know about electric vehicles. Same story over the past decade, not too much has changed except the number of BEV on the road in total.

Toyota is a conservative (not the political kind) company, so it's not that big a surprise.

Personally I think hybrids are the way forward, you don't really have range anxiety when the generator is built in. I really want to get my hands on one of those Edison motors kits and drop it into a late 60s chevy or mid 90s ford.

I'm not sold given that you've got the mechanical complexity of two types of engine systems in a hybrid.

I think just getting the charging network sorted out would basically make EVs fine for most people.

Hybrid engines have been around for quite some time, though, and they can be just as reliable as ICEs.

On the other hand, the weakness of EVs right now isn't just the charging infrastructure - it's the batteries. They're big, heavy, and very expensive to replace. This is especially true given all the new electric pickups/SUVs coming onto the market in the US. Battery tech needs to mature a while longer, IMO.

Oddbin ,

What the hell are you doing that you need to replace the battery enough for it to be classed as a weakness for all EVs??

Look up Lithium Iron phosphate batteries. They will outlive the car they're in even better than the lithium ion ones that are the majority at the moment. Those lithium ion batteries will also outlive the vehicle they're in btw. The only ones that won't are Leaf batteries because either they're an old chemistry or because nissan cheaper out and didn't put a coolant loop in them.

hybrids might be a PART of the way, but there’s absolutely no reason they need to be the only way. For many many use cases BEVs already work better than hybrids and those cases are only going to grow in number as the charging infrastructure is built out and energy storage tech improves. Maybe there will always be fringe cases where hybrids are practical, maybe not.

phoneymouse ,

In what case is a BEV better than hybrid already?

jafffacakelemmy ,

well for a start it produces 0 gas emissions at point of use. we still have to sort out tyre fragments and brake dust, and ensure the electricity grid is non-polluting too. but every hybrid car is burning petrol or diesel, just the same as we've been doing for the last 100 years or so. recent research in the uk has shown that plug-in hybrids are often not plugged in because it's too much bother.

Why not hybrid or plain ICE vehicles powered by biofuels? Even things like waste vegetable oil can be turned into viable fuel, and it can actually be less environmentally destructive than getting rid of it in other ways. ICE technology is very mature, and we currently produce more food than we need and waste much of it. Why not put it all to some use?

Pretty much any fat could be used in compression ignition engines with the right treatment, any carbohydrates turned into ethanol for spark ignition engines, and all waste wood burned for electric power and domestic heating.

Oddbin ,

Biofuels are even less efficient than making hydrogen for a fuel cell. It's the same as growing cattle for a burger. It's way less efficient an energy source because you have to grow up to 10 x more feed for the cow than you get out of the burger. You're better using that land to grow the actual food for you. Same for biofuel. You get relatively little out for the shit tonne of land you need. Still use chemicals which all need energy to make and transport and use. Then you've got to cut, transport, process, refine, transport and then use the fuel. Much better to use the land for food or hell, just leave it to be wild and soak up carbon. Then all that energy you were going to use to make the bio fuel, stick it in a battery.

areyouevenreal ,

You're forgetting things like used vegetable oil which is waste that would be thrown away otherwise. Same for the stuff wood pellets are made from, they are typically mostly saw dust and other waste products. This should hopefully cover airplanes and maybe diesel trains and some cars for when electric isn't practical.

Even if you were to start planting crops for biofuels, how much less efficient than solar plus batteries would it be? The problem with solar and especially battery storage is that the materials used to make them are not renewable, and cause all kinds of issues in their mining and manufacturing. We've grown plants sustainably for thousands of years now. I've yet to see anyone make a solar panel from sustainable or recycled materials.

Oddbin ,

Right, let's start with old oil. How much do you think is generated world wide? It's about 1/20th of the amount of oil we use currently and that created not recycled so that number is far lower so really that's a niche. Likewise wood pellets. Unless you're actively chopping trees down to make into pellets you're not going to have any real volume there. Plus as I said previously, all of that takes energy to be made into usable fuel. Where does that energy come from and also why not just use that energy directly?

As for the last paragraph, no, sorry you're just misunderstanding that whole arena. Batteries are more than 90% recyclable and that number is going up as we design them to be easier to recycle. Plus that's most likely 20 years from now on average. As for solar panels they're aluminium (easily recycled) glass (easily recycled) metals (easily recycled) and silicon (mostly recyclable) and again they're being designed to be recycled better than they were. Ontop of that they now last up to 40 years with greater than 90% of their original capacity left so basically they'll outlive most of us on here.

We've grown plants sustainable for thousands of years except for in the last 150 where we have systematically wrecked the ecology at the same time as massively increasing our population. The average westerner uses 32 times more resources than the average Kenyan. Do you want to have the same lifestyle as they have? Because they want what westerners have so that means we can't keep going as we are and have to change.

5% of our current oil demand is still a big improvement. That's probably enough to move a significant portion or even all of aviation to sustainable fuels. Aviation is one of the places where batteries don't work yet, and probably not anytime soon either.

Can you give me some evidence?

So you're saying sustainable agriculture is impossible? If so then climate change is inevitable and there is nothing we can do.

Oddbin ,

Aviation is likely to be serviced by batteries or hydrogen for short to medium flights. Long haul and cargo is likely to remain fossil fuel based for quite a while due to the nature of the fuel caution uses. If you had said shipping you might have had a point, they can burn near enough anything but they seem to be trending towards something like ammonia.

What do you want me to say other than Google it for recycling? It's widely known and has been for quite a while now. Unless you're actively looking for the opposite you should have no trouble finding independent information rather than trusting some random on social medium. But here's a few to set you off:

This one is from the energy saving trust, a non-profit government organisation and had a good round up of typical myths:

And here's an excellent talk by a Dr who's a specialist in the battery and energy storage arena:

Incidentally if you actually want to learn more about this then Everything Electric is a good start.

Sustainable agriculture for food is one thing, to make fuel is something completely different and I think you know that but are being obstuse on purpose.

Look, I get it. You don't like what you're seeing, that doesn't mean it's wrong and it's OK to change and adapt when presented with new information. The future is a mixture of technology that we have, are developing and haven't even thought of. Biofuels may even have a small niche but that's all it will be, a niche. Fully electric will be the dominant source of transport in the near future and batteries are going to make up the majority of that.

No I am not being obtuse. You talk about agriculture as if it's impossible to make sustainable. How much extra agriculture would it require compared to what's needed to feed the world? It's not something I have looked at, and I would be interested to see if you have statistics on this.

Oddbin ,

What foods do we eat Vs make into fuel? Hint, they're not the same. Sorry, there's plenty of info on all of this out there you just need to actually look with an open mind. I've given you the resources to start but I don't have the time nor inclination to continually fight these fights with people who make clearly outlandish claims and then just come back with "well prove it".

I hope you do follow the links and go and learn more but ultimately that's up to you.

Enjoy your day.
