Scotland generates significantly more renewable electricity than it consumes, hitting a record high of 113% of its electricity demand from renewables in 2022, meaning it exported surplus clean energy. It can be done!

While the percent of EVs sold in the US will go down in 2026 because of Trump Administration eliminating incentives, the percent of the vehicle fleet on the road that is EV will still increase.

Grid bottlenecks aren’t a failure of the energy transition — they’re proof it’s working.
Renewables got cheap fast, and now the grid has to catch up. Time to build the wires for the clean energy system we already have.

Data centres are energy hungry but what if we could use their waste heat to heat our homes?
That's exactly what happens in places like Finland: Cities are tapping the vast amounts of waste heat generated by data centres, and feeding it into district-heating networks.

30% year-over-year drop in October isn't nearly as bad as I expected. Given that a bunch of EV sales were likely pushed into September to get the IRS credits, the damage from ending credits will be even less in a few months, and then sales will start picking up.

EV sales *still* have not fallen, cooled, slowed or slumped. Media is lying to you.
After two years of headlines begging for failure, EV sales keep defying false media narratives that they are dropping, and continue to rise.
