Yes, Liberals leaving it to the "market"... Because COP26 is about markets, not policy. Because the Liberal carbon tax does not impact markets. Because the Liberal purchase of the Trans Mountain Pipeline ($4.5b) was all about free markets. Because we get to pick & choose.

@brorurban @TristanKamin Until the early 1950s we were almost all hydro, after which we ran out & started building coal & then nuclear, which we used to phase out coal. Now, nuclear and hydro is baseload (cover 80-90% avg. demand), with wind & solar on top and gas covering the gaps and peaks.

Switzerland has had decarb. electricity for 60 years! First relying on hydro, kept very low emissions by adding nuclear in 1970s, with no non-hydro renewables. Prices have stayed low. For 2019, non-emit hydro & nuclear = 99%, emissions<50 kg/MWh & HH prices= USD$182/MWh
