Gas price will go up someday....give EV back on the roads again.
I don't think for a long time. The root cause of low oil price nowadays was caused by several factors. Many oil exporter countries outside of OPEC wants sell their oil, not willing to cut production generally because they need money badly, Russia for example, they depend on oil for their economy why they need to cut production just to hurt their economy? Its pretty much double edge sword for them. On top of that problem, we now know much more oil reserves out there meaning supply of oil gets very high thus giving pressure on oil price to remain low. On top of that, government now requires increase fuel efficiency vehicles which won't help solve the over-supply of oil. Think about it, EV does not even need a drop of oil, what happens to the supply of oil when EV becomes mainstreamed vehicle? Its going to remain over-supply, result much lower oil price that lead to attraction using oil instead of alternative fuel which is expensive in the end.
One thing I could grateful for is that we the United States never want government to get involved with oil business, leaving only private citizen owning it, now that the private owner scramble to save their money, cut their bottom line, result? We won't be suffering like Russians does. Capitalism at best!
The truth is, the only way to have EV as mainstream type of vehicle is when we have ultra low on oil reserves, or depleted oil reserves; which is not going to happen for a damn long time, highly doubt in our lifetime.
Maybe you don't know, China is sitting on one of world's largest oil reserves and China refused to touch it, not willing to sell them to anyone... How it going to help with world's oil over-supply woes?
FYI one of my buddy asked me, and my friend to install electric outlet for their future EV. We asked for specs, WOW! Its bigger than you think, it requires 40 amperes with 240V outlet. That is a lot of juice, similar cost to run two central air conditioner/heat-pump. So think about it, having more EV will require revamp the power grid because at present, the power grid capacity is around 95% leaving only 5% So EV is not the true cost efficient solution after all.
How many watts out of 40 amps at 240V? Code requires no more than 80% of rated current, so 80% of 40A is 32A multiply with 240V equals 7,680 watts of power to recharge EV!
Not going to happen. I rather have jug of fuel with me than bulky heavy batteries to deal with, and with Jug, it is much quicker to refuel that way.
