The use of primary energy on the vertical axis is an old trick by the fossil fuel industry to mislead people into thinking that one unit of fossils = one unit of renewables. In fact, one unit of primary energy for wind or solar electricity is the equivalent of three units of fossil fuel electricity.

Another trick is to pretend we need all those fossils if we switched to renewables. In fact, if we switch to renewables, 12% of the fossil fuel energy disappears because that is how much energy is used to mine-transport-refine fossil fuels+uranium for energy, and we wouldn't need to do that anymore

A third trick is to pretend we need so much energy if we go to all electricity powered by renewables. In that case, because EVs use 75% less energy than gasoline/diesel vehicles, heat pumps use 75% less energy than combustion heating, etc., energy demand goes down another 42%.

In sum, this plot illustrates the real story of where we are and where we need to go. The proper metric is end-use energy, not primary energy.

and here's the paper

-Switch to an electric vehicle -Migrate from gas appliances (range, furnace, water heater) to electric (induction, heat pumps) -If your power grid isn’t clean, add rooftop or balcony solar -Encourage friends and family to do the same

My gut response to your post was also aggression, not because you’re preaching uncomfortable truths, but because you’re repeating fossil fuel lobbyist talking points that I’m getting really tired of seeing all over social media.

We need carbon taxes, tariffs on high-emitting countries and products, and support for adopting clean energy, clean transportation, and clean everything else. Lobbying and misinformation has made these actual solutions politically impossible to implement though, so we continue to waste resources on sponges.
