> The researchers compiled data on 662 energy infrastructure projects covering a diverse spectrum of technology classes and capacities, built between 1936 and 2024 across 83 countries, representing $1.358 trillion in investment.
This is quite a lot if we consider that net zero expenditures until 2050 only are expected to amount to 100 trillion.
World GDP was 105 trillion USD in 2024.
- XorNot 1y agoAnd over the next 25 years assuming absolutely no growth, that would be repeated 25 times for a total of 2625 trillion USD total. Which would make the year over year investment about 3.8%.
- oezi 1y agoYes, 100 trillion is not a lot over 25 years.
- Calwestjobs 1y agoGDP is PER year metric. so world generates 105T every year... so you're saying that 4% of gdp every year until 2050... it is peanuts. so for example if every household ! ! ! !ONLY IN USA ! ! ! lives in passive house, that alone will save more on utility bills, insurance, then your net zero expenditure requires to add. so im not sure if that net zero expenditure is world wide or just USAs, but USA can pay it by themselves, if they were not scammed by building bad buildings for last 20 years.... just for comparison. also previous powerplants price has to be converted to today's dollars, and inflation metric basket is flawed because it does not consist of building materials, which powerplants are build from. but it contains bread, clothing etc. so 1.358 T is not todays money that means comparation / ratio is better then you/them suggest. also NET zero expenditures means, less inputs afterwards, i.e. no/less money sent to canada, mexico, venezuela, africa, persian gulf for oil...... so more money for homeland. which most people forget about to even calculate impact of... positive for usa. so yes we can do this, but every smartass in TV is saying we can not....
- JumpCrisscross 1y ago> if every household ! ! ! !ONLY IN USA ! ! ! lives in passive house What’s a passive house?
- nkurz 1y agoIt's the English translation of the German standard for energy efficient buildings "Passivhaus": https://en.wikipedia.org/wiki/Passive_house https://en.wikipedia.org/wiki/Passive_house
- ZeroGravitas 1y agoIt's also a term that predates cheap solar and batteries. Some are trying to use "active house" to describe achieving the same low carbon goals but not limited to efficient use of externally generated power.
- okr 1y agogermany tried germany failed. people will protest, because it makes them poor. grand ideas will make people poor. because they would have to invest to make their house passive. and its a lot. but sure, try it out. :)
- oezi 1y agoGermany spent too much, too early. Prices have come down so much that the economics are completely different now.
- Calwestjobs 1y agogermany tried what exactly? concept of passive house is universal thing. most of US lives like caveman burning wood (which is not ecological nor health safe activity) and spreading nonsense about ondemand water heaters. while there are multiple billionaires who earn insane amounts on "predicting energy market" i.e. scamming residential customers / citizens thru taxes. it is like insane asylum.
