Musk: Electric Cars Will Require a Lot More Electric Power Than We Currently Have
PJ Media | Dec. 1, 2020 | Bryan Preston
Tesla Chief Executive Elon Musk said on Tuesday that electricity consumption will double if the world’s car fleets are electrified, increasing the need to expand nuclear, solar, geothermal and wind energy generating sources.
Increasing the availability of sustainable energy is a major challenge as cars move from combustion engines to battery-driven electric motors, a shift which will take two decades, Musk said in a talk hosted by Berlin-based publisher Axel Springer.
There’s no unicorn energy source or free lunch. Currently, electric cars are primarily powered by coal, natural gas, and nuclear. Those are the sources we use to generate electricity, after all, according to the Energy Information Agency. Renewables are growing but still account for less than 20% of U.S. electricity.
There’s no free lunch when it comes to renewable energy source, which may not even be all that renewable. Wind and sun are free, but the means of generating power from them are not.
They require batteries, which requires extensive mining and the use of toxic chemicals.
Mining is a dirty business.
The giant composite glass blades on modern windmills are not efficiently recyclable, so after they’re used up they end up in landfills, Bloomberg reported in February 2020.
Tens of thousands of aging blades are coming down from steel towers around the world and most have nowhere to go but landfills. In the U.S. alone, about 8,000 will be removed in each of the next four years. Europe, which has been dealing with the problem longer, has about 3,800 coming down annually through at least 2022, according to BloombergNEF. It’s going to get worse: Most were built more than a decade ago, when installations were less than a fifth of what they are now.
They’re so durable they’re practically indestructible.
…
… the blades can’t easily be crushed, recycled or repurposed. That’s created an urgent search for alternatives in places that lack wide-open prairies. In the U.S., they go to the handful of landfills that accept them, in Lake Mills, Iowa; Sioux Falls, South Dakota; and Casper, where they will be interred in stacks that reach 30 feet …
Removing them and transporting them to landfills increases windmills’ energy footprint over time.
