Wholesale vs Retail Car Sales: Why They Differ
A car is ‘sold’ twice — once from factory to dealer, once from dealer to buyer. When those two numbers diverge, the gap is exports or unsold inventory, and knowing which is how to read a sales headline.
Australia’s Battery Revenue Halved. Then Came the Spike
New South Wales grid batteries earned an estimated AU$5.63m in two hours as prices hit AU$23,107/MWh — even as Australia’s quarterly battery revenue halved year-on-year.
Tesla’s Flying Roadster: What Was Shown, and What Wasn’t
Tesla’s new Roadster hops, spins and promises 0-60 mph in about a second, yet its range claim has halved since 2017 and no battery size was given.
China’s Holiday EV Charging Hit a Record. So Did the Waits
China’s expressway EV charging hit 163 million kWh over the National Day holiday, up 51% year on year, with a record 28 million kWh on day one — and seven-hour waits at the worst service areas.
Nameplate vs Effective Energy Density: Fuel’s Real Lead
Diesel carries roughly 60 times the energy per kilogram of a battery. But an engine wastes most of it while an electric motor wastes almost none, so the real gap in useful work is nearer 25 to 1.
South Africa Orders 4.6 GW of Batteries, No New Solar
South Africa’s first procurement off its new energy plan orders 4,600 MW of batteries and 5,000 MW of gas-to-power — and zero new wind or solar. The reason is a grid with too much power, not too little.
Must-Run Generation: the Fossil Floor That Spills Solar
A coal plant can’t switch off at midday – below about a third of its output it goes unstable. That must-run floor, not a lack of wires, is why a sunny grid spills solar instead of coal.
The BrightVolt Take: Home Batteries Doubled in Power, Not Size
The median US home battery nearly doubled its power in a year – 6 to 11.4 kW – while its storage stayed flat at 13.5 kWh. Buyers aren’t paying for more hours. They’re paying for more muscle.
The BrightVolt Take: America’s Balcony-Solar Bottleneck
Germany has plugged in 1.3 million balcony-solar kits; the US has almost none. California just legalised it – but the real barrier was never the law. It is a missing standard and a $500 device.
