Another data point from the youtube video : average price in the simulation is at $83/MWh, while current average prices are at $170/Mwh in Australia. This is a great economic incentive to go the 9x% renewable path.

According to: https://en.wikipedia.org/wiki/Solar_power_in_Australia Yearly PV capacity increase is between 3 and 4 GW, so tripling PV as the simulation assumes starting from 27 GW means between 11 and 15 years to reac

Gas turbine are the cheapest electricity generator to build, only expensive to operate due to fuel cost. That's why people don't mention overbuilding gas2power capacity. Data from: https://www.eia.gov/analysis&#x2F

You can also be more efficient with heat pump than with direct gas heating, including when producing electricity from gas, eg: https://twitter.com/DrSimEvans/status/1560556804051968000 "Thought experiment: 1

I second this, meshcentral is very good and efficient, works on Windows and MacOS too, developpers are very responsive.

Fun fact: a standard parking spot of 2.5x5 meter covered with regular PV panels will produce in a year (in my country) about 2.5 MWh which is enough to power an EV for 16000 km. Of course less than needed in winter and more in summer. Edit:
