>The problem is, wind energy is not reliable.
No, that's story-telling and hand waving about a topic you clearly don't understand. It's like complaining that high-level languages can't possibly work because compilers just aren't clever enough to output clean code.
Firstly, offshore really isn't that intermittent. Secondly on-shore isn't built where your semi is in the middle of the city. It's built in - you know - areas where the wind blows. Because building it where your semi is would be really stupid.
Clever people do a lot of modelling and statistical estimation of potential sites, and bankers won't fund projects if the numbers don't work out,
Because the numbers are conservative - those bankers have their uses - wind reliably outperforms the estimates.
Finally, we have this thing called a National Grid, which means - here comes the clever part - that it's possible to move electricity from where it's generated to where it's needed.
Now, as for energy generation - there's been relentless hostility to renewables from the fossil dinosaurs for decades now. They really, really hate the fact that they're not going to able to keep holding everyone to ransom with fossils. (If you think wind is unreliable, why not rely on Russian gas instead? Genius...) So offshore wind build out is some tiny percentage of what it could be.
In spite of this - more than 8% across the EU. That's an incredible achievement, and well above most predictions.
And longer term - do you think we should burn oil to keep warm, or should we keep it for useful things, like plastics?
Elon Musk is betting the farm on electric travel being the future, and if he had to go brain to brain against Lewis Page in an IQ battle, I know who I'd be betting on.
