EYE-OPENING FACTS ABOUT
ELECTRIC VEHICLES YOU NEED TO KNOW
Electric vehicles (EVs) are less expensive to operate and own
than the now outmoded combustion engine cars. Electricity is cheaper
per mile than gasoline, and electric motors are way more efficient
at moving you down the road than combustion engines (a motor wastes
very little fuel energy as heat, an engine wastes a lot).
EVs are capable of being much safer than combustion cars... there's
no engine under the hood that can be pushed into the passenger
compartment in a crash, plus there's all the safety and anti-collision
technology that takes advantage of an EV's design.
EVs have far less moving parts than combustion cars, so less to
break and much less maintenance; change only tires and wiper blades,
no oil changes, belts, hoses, fuel and oil filters, spark plugs,
fuel injectors, timing chain, oxygen sensors, muffler, radiator
and transmission fluids, etc. Even brake pads and rotors last
a lot longer because electricity generated by the motor helps
to slow the car down.
EVs take 12 seconds to charge: 6 seconds to plug it in when you
get home, and 6 seconds to unplug it the following morning...
less time than a gas station visit.
Just as cell phones now have "Turbo Charge", the modern
lithium-ion batteries in EVs can be charged very fast at charging
stations equipped with fast chargers, and there are plenty of
them. And there are EVs designed from the ground up allowing for
large battery packs, so no "range anxiety" on long trips
(especially if your EV automaker provides a worldwide
is now commercially viable, thanks in large part to the kick in
the automotive industry's pants by Elon Musk and Tesla Motors.
Affordable mass market EVs require economies of scale, and this
requires adoption. So when there's a choice between a gas powered
car and an EV, and the prices are close, we as tenants of this
planet have an obligation to give serious consideration to the
environmentally friendlier, non-harmful option.
Oil is not
an unlimited resource, so we must transition to sustainable transportation
eventually. And because of the current rising global temperatures,
it's not a case of "the sooner the better," it's
more like "we need to do this now to avoid irreversible
catastrophic consequences down the road." I'm
not trying to use scare tactics, I'm just dealing with reality.
And speaking of reality...
But aren't the emissions still mostly just moved from the road
to the coal-fired power plant when switching from a gasoline car
to an EV?
Let's say you charge your EV at home, and your home gets its power,
not from a nuclear or hydroelectric power plant, but from a coal-fired
plant. You aren't simply moving the creation of greenhouse gases
from the car to the power plant in a 1:1 manner. Here's why...
of economies of scale, one gigantic power plant serving 1000 electric
vehicles can be more efficient than 1000 separate power plants
(one in each gasoline powered car). Think about what it would
look like if you collected all the tailpipe emissions in a huge
bag from a gas fueled car driven 100 miles. Now imagine the additional
smoke stack emissions from a power plant that's charging an EV's
battery to replace the energy it just used for a similar 100 mile
drive. The difference is like night and day, for reasons #1 and
2. An average
gas powered car can get 24 MPG, but an EV can get three to four
times that in MPGe. So, much less fuel energy required for those
1000 electric cars than for 1000 gas powered cars driven the same
distances, resulting in much less emissions.
3. The emissions
from a power plant can be "scrubbed" to reduce air pollutants
and CO2, but this is not feasible for a fossil fuel car.
refining plants require lots of electricity to turn crude oil
into gasoline. Since this energy production is unnecessary with
an EV infrastructure, this needs to figure into a "well-to-wheels"
analysis when considering emissions.
5. And remember,
coal-fired plants can have fields of solar panels added to them
to reduce the amount of coal they burn (already being done). And
in the future they can be replaced by renewable energy power plants.
So your electric car runs cleaner as infrastructure improvements
And if solar
panels and an energy storage system are added to a home or business
(already being done), an EV can be recharged from the sun, or
from other zero emission sources, resulting in a "Zero Zero
Emissions Vehicle". And how about that, Tesla has pioneered
"The data show that cars with internal
combustion engines were not clean in the past, are not clean
today, and will not be clean in the foreseeable future.
The auto industry will always find new ways to circumvent
tests and optimize results. The only way to ensure cars
are truly clean is to accelerate the shift to zero-emission
technology and electromobility."
