Côté facture, Nathalie a constaté une baisse jusqu’en 2019. La facture annuelle de chauffage est en effet passée de 836 euros en 2016 à 500 euros en 2019, Les travaux ont coûté 35 000 euros à Nathalie et son mari.
Soit 336 € par an d'économisé... 104 an pour amortir le coût de la rénovation ! Il faudrait peut être utiliser ces investissements sur des optimisation plus efficaces que l'isolation à tout prix.
Time is running out on the climate, how many decades can we wait for the "perfect" solution to show up when we have a good enough one right now they can help?
A l'heure où Oxfam, spécialiste des stats bidons, son rapport où les émissions sont estimées comme augmentant linéairement avec le revenu, un papier récent de l'INSEE qui explique c'est nettement plus complexe et que non, gagner 10x plus ne veut pas dire polluer 10x plus.
They could. Someday.
Nuclear can, now.
How long will it take for us to get good enough batteries?
Including the time to manufacture and install them at utility scales (we are talking powering an entire nation out of batteries for hours), way more than a decade.
Batteries are already being installed on grids but they can only help so much smooth out power delivery. They are very very far from having the ability to completely take over an entire grid.
Germany has tons of solar and winds and yet it is pretty common to have neither (windless nights) at which point the entire grid needs to be powered by non renewables. That's a lot of standby power.
No it doesn't. Cheap solar is great but even if it was $0, you'd still need some other tech to provide electricity when the sun is down. So it's either gas, batteries, nuclear, etc. but you can't just use solar alone.
And until batteries get good enough, nuclear is the cleanest option we have.
I learned the same lesson the same way 😞
I'm not sure what you mean by "hypothetical", these aren't hypothesis, these are their definition. And their definition means they are limitless, just as the definition of "beauty" or "numbers" make them limitless. They aren't bound by the physical world.
(also dollars are equally abstract, currencies exists as human convention, having $1 billion more in your bank account is just a few bits flipped in a database)
No, that's literally the definition of growth (the variation of GDP from one year to the next, the GDP itself is defined as the sum of gross value added). We can make growth out of thin air if we want, it's a purely accounting metric.
I sell you a pebble for a $1000 and you sell it back to me and we created $2000 of growth without anything physically happening.
We can just recycle coal/natural gas/oil after burning it?
Indeed we can. That's not to say we should keep burning those resources right now, but the carbon is not disappearing into an alternate universe either.
He was always like this and has been distributing public money left and right. France's public spending and taxation as a share of GDP are at all time highs.
It's just the French left thinks everybody to their right is a spawn of Reagan and Thatcher.
