EVs, Power Bills and Emissions

How do we change a system employed by government?  If we went cold turkey on many of our traditional national policies the flow on effects throughout the public and business sectors would be ruinous.  If you believe the headlines which state that traditional motor vehicles are heading for a cliff edge where there will be no more fossil fuels available to power them, and that the environment will be so much the better without vehicles that are powered by conventional fossil fuels, then things look pretty dismal.  But is this actually so?

There are numerous countries around the world that have their special governmental team of policymakers pushing for electric vehicles (EVs) to be subsidised and made easier for those who can afford an expensive EV to buy one.  Across the ditch the New Zealand Labour/Green government are creating a fast track for EV purchase in the hopes to lessen greenhouse emissions and keep NZ green.  And in America they have recently brought in policy that reduces the initial purchase price of an EV by up to $7500 USD.  Of course, the subsidizing is paid for by the tax payer.  Those who cannot afford to buy a new electric vehicle pay for the privileges that the wealthier EV owners enjoy – like free use of public charging stations and preferential access to carpool lanes.  What about the grand schemes and plans of making some American States totally EV and thus pronouncing the ban of all internal combustion vehicles by 2040 (California).  Is this really fair?

Could this thinking and ideology be the motivation behind EVs in Australia?  How could the typical Australian on an average wage manage a law that states that you must drive a new and expensive EV by 2040?  By the way, we’ll also use your current taxes to help the wealthy buy an EV quickly (and enjoy its benefits) while you struggle to put the food on the table, let alone by an EV!

Let’s also remember that most of Australia’s electricity is made by coal and other natural resource plants.  A large fleet of EVs across Australia will draw down on the current available power supplies very heavily.  But wait, I know, we could use people’s current taxes to build more expensive cleaner power plants and provide bigger, better power networks!  That will make Australia a better place.  Power companies will enjoy the profits and will be sure to put the price of power up once electricity comes in short supply.

Hang on!  Are electric vehicles really as great as they claim to be?  Supporters of the EV suggest that EVs will reduce air pollution and tackle climate change.  But will they?  (Climate change is another issue – and one that many can make plenty of money, too)  It’s evident that a new vehicle powered by the modern conventional internal combustion engine is, in fact, way more pollutant-free than one might tend to think.  Extracting Lithium and other materials for batteries has an environmental impact of its own.

The appropriate comparison at governmental levels for evaluating the benefits of all those new electric vehicle subsidies, mandates and ideologies should be the difference between an electric car and a new petrol-or-diesel-car.  New internal combustion engines are very clean and emit only about 1 percent of the pollution that older vehicles did back in the 1960s.  New innovations on internal combustion engines continue to improve these engines and their efficiency and cleanliness.

When we consider EVs, and their large appetite for electricity, the energy to power them has to come from somewhere.  Cars are charged from the nation’s electrical grid, which will mean that they’re only as “clean” as Australia’s mix of power sources.  An environmental impact in the mining of the lithium, cobalt, and nickel that go into car batteries is evident.  Extracting Lithium is actually not so bad; most of it is extracted from brines that are evaporated by the sun, but it has a sizeable carbon and physical footprint.  We have a long, long way to go before the production of electricity for the main grid looks as green and as clean as an EV appears.

What’s the inexpensive answer?
