Separate names with a comma.
On long trips, I've compared the computer estimate to that measured at the pump. Average is within 1.5%. Since the pump accuracy is only...
Only if you have a place to put it.
Yeah, well, duh! Coal is close to 100% carbon. So if the above is true, a kWh of battery production production produces about the same CO2 as...
I used the words "energy cost" for a reason.
You all should read this: Energy returned on energy invested - Wikipedia Some highlights: "In physics, energy economics, and ecological...
When the energy cost of petroleum is calculated, all of that is included.
So, no.
Got any evidence of that? Wind and solar powered mining trucks, heavy transportation, ships and processing plants supplied by solar and wind? Do...
We wouldn't - that's my complaint. We have to include the entire process, including materials, manufacturing, transportation, etc. "Cradle to...
I'm saying battery manufacturing and oil cannot be compared.
For manufacturing, everyone does. When we do this for wind energy, we include the source materials, manufacturing, transportation, erection,...
No, that's apples (energy storage) to oranges (primary energy source).
The same way everyone else does and the same way as the numbers I quoted earlier - life cycle energy cost.
Perhaps, but the only technology that exists in small sizes that has both high power-density and high energy-density is the turbine engine (and it...
That's a horribly misleading statement because it doesn't include any of the energy cost of the supply chain, the construction of the energy...
This is why I have a PHEV. I gain time and freedom when I'm home (since I don't have to fuel up) and I gain time and freedom when I'm away from...
In my experience, they don't. But lots of other things do, none of which I carry spares for.
No one is fun at parties.
That isn't so. We do better on energy generation than on storage because we don't know how much batteries will improve, or if they will at all....
I suspect it's more simply because more than that have a second (or third...) car. In that case, I'd argue a first-gen Leaf has sufficient...
