Back there a ways, two roads diverged. Maybe the one less-travelled would have been a better idea.

Bar chart showing renewables percentage of total energy consumption. 1990: 15.1 percent. 2022: 17.9 percent.

How much renewable energy do we use?

Probably less than you think.

The World Coal Export Market

It's a dirty business. But somebody always decides to do it.

Australia and China are tied for third among nations with major coal deposits. They each have 13% of the world's reserves.

EU greenhouse gas emissions continue to drop

The EU met its 2020 emissions goals at least 10 years early, and had remarkable success in its 2023 reductions.
