German anti-nuclear activists like to tout the percentage figure of renewables in the country, but that's not the right metric to look at : the coal+gas baseline is so bad in terms of CO2 emissions, that even in ideal conditions when w

Germany absolutely is relying on coal and (Russian) gas to afford its ideological decision to prematurely sunset nuclear plants, at the worst possible time in history : just as climate change becomes an emergency. The cold hard truth is tha

You're being disingenuous now. It feels like arguing about aviation being the safest means of transportation and having someone answer "but it's scary and deadly when it happens!" This will be my last answer. It's o

So on the one hand with nuclear, we're talking about one swimming pool's worth of waste since the beginning of the French nuclear programme. Currently stored safely enough, long term solution identified and implementation in pro

The incontrovertible problem remains : wind/solar are intermittent, peak load sources (Germany doesn't have the geography for hydro) No matter how you spin this, you NEED to pick one of either nuclear, gas or coal in your mix to c

Nope sorry, it takes all of this into account. From their FAQ : "We use a life cycle analysis (LCA) approach, meaning that we take into account emissions arising from the whole life cycle of power plants (construction, fuel production,

These percentages are largely irrelevant because coal remains the only non-intermittent source that Germany can rely on (in the absence of nuclear), and it's so much more carbon-intensive than the rest that the average figures are stil

You're just focusing on the wrong metric. Because coal is so bad in terms of carbon intensity (800 gCO2/kwH), Germany's greenhouse gas emissions figures are still terrible on average. "Why Aren't Renewables Decreasi

> Germany is heavily investing in solar and wind. Why do you bring up coal? Because coal is what Germany really relies on in practice, making it one the worst industrialised nations when it comes to CO2 emissions per kWh. Check for yours

Let's put the myth of nuclear waste to rest by putting things in perspective : The amount of energy required to run France's trains for one whole year is 9 TWh. In terms of waste you can take your pick between : * assuming 100% nu

Whatever you say, the hard inconvenient facts remain and as I write this around midnight CET, coal is the #1 source of electricity in Germany, and their CO2 emissions per kWh are 5.71 times those of France. You simply cannot solve this prob

Their "heavy investment" in renewables doesn't do much for Germany. It's really coal and gas "saving" them from nuclear, and that's problematic. https://www.electricitymap.org/?page=country
