China's E-Buses Dent Oil Demand More Than Electric Cars Do (bloomberg.com) 148
China's fleet of electric buses appear to be denting oil demand more than electric cars. "By the end of this year, a cumulative 270,000 barrels a day of diesel demand will have been displaced by electric buses, most of it in China," reports Bloomberg, citing a new report published by BloombergNEF. "That's more than three times the displacement by all the world's passenger electric vehicles (a market where Tesla has a share of about 12 percent)." From the report: Despite rapid growth, the impact on the oil market from electric vehicles remains relatively small. Collectively, buses and electric vehicles account for about 3 percent of oil demand growth since 2011, and 0.3 percent of current global consumption, according to BloombergNEF figures and data from the International Energy Agency. Buses matter more because of their size and constant use. For every 1,000 electric buses on the road, 500 barrels of diesel are displaced each day, BloombergNEF estimates. By comparison, 1,000 battery electric vehicles remove just 15 barrels of oil demand.
Still, the EV market's impact on oil consumption is only going to grow. By 2040, electric vehicles could displace much as 6.4 million barrels a day of demand, while fuel efficiency improvements will erase another 7.5 million barrels a day, according to BloombergNEF's May 2018 long-term EV outlook.

Trolleybusses a) need a temporary shutdown of the roads until the wires are put up, c) need complicated wiring at crossings, and especially at central bus stops, level crossings with streetcars and electric trains and c) are not very flexible when it comes to rerouting compared with diesel busses.
Installing Trolleybus wiring isn't particularly disruptive. The wiring on our local trolleybus (MBTA 73) was removed a few years ago for a major road rebuild and later replaced without much fuss. Also battery operated busses have to be taken out of service periodically and parked somewhere for recharging and they have to carry very heavy battery packs, which increases their energy consumption. You are right, trolleybuses are less flexible, but that lack of flexibility can be an advantage in encouraging tran

And I bet fleet owners like it, too - EVs have much lower operating costs and lower maintenance costs, which are a big deal for fleets.
On the flip side, globally there are over 900 million cars on the road, vs perhaps 100 thousand busses, so there's a lot more fuel consumed by cars than busses, so while each car has less impact, they outnumber busses by 9,000:1, so converting all of them to EVs would have a lot more impact.

So +6 MPG @ 14 MPG results in more fuel savings than +25 MPG @ 25 MPG. A +x MPG improvement represents more fuel savings at lower MPG than it does higher MPG. The rest of the world measures fuel consumption in liters per 100 km to avoid this problem. That's a direct measure of fuel consumption, not an inverse.
This means econoboxes are actually the worst vehicle to convert to a hybrid. They already use very little fuel, so the potential fuel savings by converting them to a hybrid is even smaller. And you're spending a lot of money on a hybrid drivetrain for a very small fuel savings. The hybrid SUVs that environmentalists scoffed at are actually the best personal vehicles for converting into hybrids. Likewise, you get the biggest fuel savings when you convert pickup trucks, buses, and tractor trailers to hybrids or electric. Musk understood this, which is why he produced an electric semi-trailer truck. There are roughly 2 million semi-trucks in the U.S. vs 250 million cars. Yet the semi-trucks consume nearly as much fuel as the cars.
(The same problem affects hard drives and SSDs. MB/s is actually the inverse of how we perceive drive speed. We think of speed in terms of how long we have to wait for the drive to complete an operation. So those multi-GB/s sequential speeds that NVMe SSDs can hit actually make very little difference. They're so fast the operation is completed in the blink of an eye. It's actually the smallest MB/s speeds which make the biggest difference. If your NMVe SSD can only manage 30 MB/s 4k reads, even a small number of small files which need to be read will easily make you wait for a longer time than hundreds of MB of sequential data. If you want a good SSD, ignore the sequential speeds, get something with fast 4k speeds.)
