does anyone ever assume that it's anything other than the grid when it comes to some article like this?

electricity is't the majority of the energy consumed in nearly any country.

it's a easy way to keep confusing less vigilant people by calling electricity as energy.

Just call things the way they are.

You're right; 2/3 of worldwide energy is actually waste heat.

Here's the chart from 2007: Waste heat / losses are in the top right, although it doesn't show the transport sector losses which are higher than for coal generation.

What this means is that when we fully electrify all sectors, by using renewable energy such as wind and solar, our total energy generation capacity will only need to be about 1/3 to 1/4 of what we currently produce today to fulfill our current energy needs. That's huge.

that's not quite right and mixes couple things

you have production losses and transmission losses. then you have waste heat used for household and industrial heating.

now you would also have to produce that portion electrically.

For instance in winter heating requirements of a typical house are 2x that of the electricity used.
