This is the kind of comment that sounds "wise" and "realistic". But it's important to think a bit deeper.

Existing electricity generation goes to powering existing consumers. We'd burn those fossil fuels whether or not we bought more electric cars. Electric cars are a new electricity consumer. So the source of energy for this additional electricity is what matters.

In 2022, 83% of new electric capacity was from renewable sources. [1]

We can quibble about timing issues. For example, there's a lot of solar energy during the day but electric cars are often charged at night. But it's clear that renewable energy and electric cars are rising together.
