PDF Fossil Energy Study Guide: 300 million years ago

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

Lithium Mining: The Hidden Environmental Cost of EVs

There, in a nutshell, is the logic behind carbon taxing: to raise prices of fossil fuels in accordance with their true costs, thus spurring reductions in their use. Lithium, no less than coal, oil and methane, should be forced to adhere to the same dynamic. If electric vehicles and carbonfree grids are rendered more expensive for awhile, so be it.
