The current Germany infrastructure total cost is around 500B€ in 20 years. That's for sure a few brand new nuclear power plants, or a few big investment plans in power efficiency (heat pumps, isolation…).
Wind turbines lifespan is around 25 years (some 30 years), mostly limited by structural and physical issues. You can't reinstall a new wind turbine on top of an old one (the concrete base is also fragilized and new turbines are often way bigger than old ones).
Solar panels indeed have a way better lifespan and recent ones stay efficient even after decades of use.
So one question now: why is Germany building and importing so much natural gaz (~400g of CO²/kwh, it's around 10 for renewable/nuclear) if their renewable plan is working so well ?
- pydry 5y agoThey're using about the same amount of natgas they did 10 years ago. I presume they will start scaling down natural gas plants at some point, but they're clearly aiming to shut down nuclear and lignite plants first. Coping with increased electricity demand and switching off two forms of power generation entirely wasn't going to be quick but it is inevitable.
