Is the creator of the meme at left serious?  From this piece:

Electric Vehicle Drivetrains Only Have 20 Moving Parts Compared to Over 200 in Conventional Automobiles

This means lower maintenance costs and a radical shift in auto industry job skills.

While most of the media attention focuses on the big picture issues of how green-energy EVs are destined to help mitigate climate change by eliminating use of fossil fuels and will ultimately lower the costs of driving for consumers, there is another significant impact that deserves more attention too. That is the relative simplicity of EV powertrains and implications for lower maintenance costs.

Many EVs don’t even need a transmission. Those that do use a much simpler, single-speed system as opposed to the multi-speed gearboxes in gas-burning vehicles. For example, Tesla’s electric motors only have two moving parts and use single-speed “transmissions” with no gears. The company says its drivetrain has about 20 moving parts compared with 200 in conventional drivetrains. Similarly, the all-electric Chevrolet Bolt has 80% fewer moving parts than a comparable car with a gasoline engine.
And absent the power train, think about other entire systems that do not even exist in EVs, e.g., fuel delivery, pollution control, and exhaust.

At left is an interesting twist on the case for social democracies.  In short: Investing in people pays off.

As they say, Education is expensive, but the cost of ignorance is far higher.

Hitting the Tipping Point

Have we hit the tipping point on climate change?  For example, has the melting permafrost in the Arctic released so much methane that a runaway feedback loop has been established?

As suggested at left, an analogous question could be asked about the level corruption in the U.S. government.
