Solars capacity factor is around 20-30 or something like that. It's not even close to being a realistic deliverer and wind doesn't change that either.
I am not joking here. If you can point me to any solution that can economically power ex. the shipping industry using electricity please point me to it so I can invest in it right away.
The reality is that we are decades if not longer away from anything close to the dream scenario you read about everywere around you which becomes very very obvious the second you start looking for investment opportunities and is a good reason why it's primarily driven by politicians, not the market.
Investments in solar and wind are declining too because china is reducing its investments. If it was so great why wouldn't the private market just take over?
My guess is that in 5 years a lot of people are going to get a rude awakening when they finally realize they've been told dreams rather than reality.
But as I said. If you can point to actual solutions to these problems then please let me know so I can invest.
- adrianN 7y agoYou say "economically" as if there was an alternative to stopping global warming. The shipping industry won't survive catastrophic climate change. That being said, if you google around a bit you find a number of studies showing how 100% or close to 100% renewable energy can be achieved with today's technology. There is for example http://energywatchgroup.org/new-study-global-energy-system-based-100-renewable-energy http://energywatchgroup.org/new-study-global-energy-system-b... or this (just for Germany) https://www.ise.fraunhofer.de/content/dam/ise/de/documents/publications/studies/Fraunhofer-ISE_Energiesystem-Deutschland-2050.pdf https://www.ise.fraunhofer.de/content/dam/ise/de/documents/p...
- ThomPete 7y agoI don't need to google around, I know the litterature and I know the difference between what can be speculated and what can be demonstrated :) So don't worry about that. Fusion is theoretically possible that doesn't mean we are even close to it and neither wind nor solar will be able to deliver anything close to the amount of energy (not just electricity) we need. Again point me to a concrete solution that is currently being developed and I will invest instantly. With regards to climate change then, first of all, it's not going to be catastrophic not even IPCC thinks that. Second of all the climate has always been changing and giving us challenges with fossil fuel we've managed to combat most of that. You live in a rich society BECAUSE of its use of fossil fuels not despite of it. Nature doesn't give us a safe and friendly environment we make unsafe, it gives us a hostile and dangerous environment we then make safe. Try and give me a single example of a scientifically demonstrated consequence of the climate changing we can't deal with today.
