So the renewable buildout massively decreasing these countries emissions are at the same time increasing it???

cyberax 2y ago
Europe's emissions have been mostly flat since ~2014: https://www.iea.org/regions/europe/emissions https://www.iea.org/regions/europe/emissions The lack of reliable winter-time generation is now slowing down the adoption of heat pumps. I'm most familiar with the German situation, and it simply can _not_ transition to heat pumps because there's not enough generating capacity. Even though heat pumps are more efficient than just directly burning gas for heating. So Germany had to outright _subsidize_ new natural gas power plants. But it's all fine because they pinky-swore to make them "hydrogen ready". A better market response is to add _capacity_ markets where operators can buy committed generating capacity. This will de-incentivize adding of cheap low-quality generation, and provide a market boost to energy storage and/or nuclear.

  Which is a completely different topic from the grid composition. Go look at these countries grids carbon intensities and tell me they have been ”mostly flat”. https://imgur.com/a/eCxUpZ2 https://imgur.com/a/eCxUpZ2 You do know that nuclear power takes about 15-20 years from political decisions create horrifically large to an operational plant. What problem in the 2040s are you aiming to solve? Should we just not build heat pumps until then while waiting for this nuclear power to come online? That would be pure insanity.

    Your graph is misleading, as it cuts off at 2020 and starts in 1990. The majority of the decrease is attributable to de-industrialization, the switch from coal to natgas, and energy-efficient lighting. That was mostly pre-2014. If you look at Germany since 2014, the end result is not great: https://www.nowtricity.com/country/germany/ https://www.nowtricity.com/country/germany/ Compare that to France: https://www.nowtricity.com/country/france/ https://www.nowtricity.com/country/france/

      What is it with the never ending stream of excuses when reality does not align with the nuclear cult? The graph goes to 2024. In Germany since 2011 coal is massively down, nuclear is down to zero fossil gas is stable. It is all replaced by renewables. Then you go and make the amazing comparison that we should care about one instant, rather than the cumulative emissions and progress towards a decarbonized grid. Given a blank slate with money to spend what does Germany do today to combat their current 330 gCO2/kWh? Do they continue to invest in renewables chipping away at the problem given todays renewable costs or lock in their current emissions, which you decry, for decades while waiting for horrifically expensive nuclear power to come online?

        > What is it with the never ending stream of excuses when reality does not align with the nuclear cult? Just show me the pathway to at least 60g/kWh CO2 footprint for Germany. I'm not asking for too much. Otherwise, it's the same old story: "Oh, we already invested $500B in Energiewende, and it didn't deliver. But it's too late now to switch to nuclear, so we need to raise the energy prices more for more Energiewende goodness!" > The graph goes to 2024.

The proof is in the pudding. The German "green energy" transition has reached its practical limits. We can see some variations in the CO2 intensity due to weather and business cycle effects, but it won't go down much more than the current level.

The renewables buildout is actually not "massively decreasing" these countries emissions. Germany's emissions are largely flat, most of the little decrease has come from reduction in total electricity production. Emissions are around 10x that of France.

  Why are you lying? Can’t you even find it good that renewables are massively decreasing grid emissions around Europe? Here’s the data: https://imgur.com/a/eCxUpZ2 https://imgur.com/a/eCxUpZ2 This doesn’t even take into account energy efficiency measures lowering total grid demand.

    What I wrote is absolutely correct. After more than 20 years of renewables build out, Germany still has 10 times the CO₂ emissions of France. And France achieved that in 15 years, 40 years ago. Again, we've been at it well over 20 years and have barely moved the needle. https://www.researchgate.net/publication/333217852/figure/fig5/AS:765097723064323@1559424920973/CO2-per-kWh-electricity-generated-in-different-European-countries-2014-own-compilation.ppm https://www.researchgate.net/publication/333217852/figure/fi... And still the 2nd or 3rd dirtiest grid in Europe. So no, what I wrote absolutely stands.
