Think of CO₂ removal like a time machine. How far back does planting 100 million trees take us? One mature tree takes up ~25 kg of CO₂/year, so 100 million trees will take up 2.5 MtCO₂. That's a time machine that takes us back ~33 minutes in a year. Nature will not save us from fossil fuel CO₂.

Electricity ratepayers feel pain from *bills*, not prices. If my price goes up 10% but my energy use goes down 20% (from insulation or a more efficient air conditioner, say), then *my bill goes down 12%*. Energy efficiency is weirdly absent from discourse on electricity affordability.

Corn ethanol serves no purpose and is purely a handout to farmers. It costs more and emits more than normal petroleum. And it takes up half as much land area as all urban and suburban land in the US. If we replaced the land with solar, we'd get 3x as much power as the US uses.

The next tipping point in the energy transition is approaching. Overall, solar has already been cheaper than fossil power for a while, but upfront costs used to be higher. That's no longer the case. Solar is now competitive upfront AND has vastly lower operating costs (no fuel).

We bought an EV years ago and have so far saved over $7000 in avoided gas costs. And our electricity is now free because our solar panels have completely paid for themselves in saved electricity costs. My interest in the price of fossil fuels is purely political.
