@acoyne Why, in your list of measures to reduce exposure, did you not list green energy development?

Especially Canadian home solar power, which immediately provides energy security to that household, and is advertised (below 50° latitude) as having an 8-10 year payback period?

I can see not going into the weeds on other green energy sources. Canadian geothermal energy is just starting to be tapped. Wind power installations, according to Wikipedia, were 6.5% of Canadian power generation back in 2020. Whether uranium provides clean power or not depends on who you ask, but we have it.

But home solar is like energy victory gardens that don't need watering or weeding.

Article on the Sherco coal-to-solar transition: cnn.com/2024/09/16/climate/coa

Touches on several themes: Coal-fired power plants can make great sites for utility-scale solar installations--the transmission lines are already there; coal can still be used for a while, while the solar array is being built out; intermittency of fossil-fuel power plants; and wind & solar being far cheaper sources of energy than coal.

"The life cycle emission intensity of solar solar photovoltaics is approximately 40 gC02/kWh."
- Zero CO2 emissions in the energy sector is therefore not currently possible in practice if we consider it globally and not just locally.
- If the EU were to buy these panels from #China then the emissions associated with the production and recycling of the panels would be shifted abroad and the EU would be seemingly "emission free" (but its territory is not under a glass lid).
- Although solar energy is significantly less carbon-intensive than coal or gas, it still produces carbon emissions.
- the key question is what the EU will pay for those imported solar panels with if, in time, the #BRIX countries reject the devaluing euro (devaluing for the very reason that the EU's economic problems are solved by issuing a new Euro, thus reducing its purchasing power)
- or will the EU manufacture the panels on its own territory? But from what, and how will it do it with zero emissions?
