#Finland and the rest, pay attention to this 👇🏻 Nuclear power is not the way foward 👎🏻

1/ New @lut.fi study in collaboration with European partners finds prioritising nuclear power expansion over renewable energy (RE) leads to 71–84% higher annual system costs in Finland by 2050 compared to a cost-optimised RE system. doi.org/10.1016/j.en...

DAC is largely needed primarily for CCU (e-fuels). Why novody thinks if that is a miracle - maybe because integrated assessment models do not include the technology - with the past bias of the @ipcc.bsky.social report on IAMs it not ended up in the last assessment report.

This would be true for a current policy scenario. Our study does not do this - but rather deploys a best policy scenario: Massive investments in renewable energy, net-zero emission system by 2050 and subsequent removal of 500 GtCO2 for 1.5°C and 1750 GtCO2 for 1.0°C by 2100.

The most annoying part of being a researcher: Investing hours in adapting research proposals (for paying your own salary) to specific requirements and layouts of funders over and over again, so that a REVIEWER can kill it because he/she doesn‘t like it (w/o getting reviewer reports after rejection)🤦🏻‍♂️

"huge solar PV demand for Africa ahead" - that's what we find since year. The energy system solution for Africa is largely PV+battery as the core & most important backbone.

According to a new analysis from @ember-energy.org , Africa is showing signs of an impending solar boom! Imports of solar panels have increased 60% over the last 12 months across the continent as a whole, with 20 countries reaching record levels. ember-energy.org/latest-insig...

There has been a major pick-up in solar panel imports into Africa over the last 12 months - a shift that is likely to impact almost every country on the continent.

It seems that in the vastness of your intelligence the ability to read and the difference between tidal energy and wave energy got lost. You just proved yourself that a troll is what you are. Sad. I was hoping for top quality trolling here.

Dominik Keiner @dominikkeiner.bsky.social · Aug 18

„Potential“, „can“, „could“. Come on, troll, you can do better than Google AI. Give me at least something real to „educate myself“. The quality of trolls was definitely better on X…

Says the account which only purpose it is to troll without any science- or evidence-based arguments adding nothing which would be helpful to open a serious discussion. Please stop commenting unless you have something valuable to say. Thanks, and have a good day.

Meine ursprüngliche Frage war auch eher rhetorischer Natur.

Dominik Keiner @dominikkeiner.bsky.social · Aug 13

Logisch. Ich meinte dass es offenbar einfach ist zu messen. Die flächendeckende Installation von smart metern ist m.E. keine Hürde und könnte in wenigen Jahren umgesetzt werden. Bei meinen Eltern war das für eine Balkon-PV im nullkommanix erledigt.
