Sorry. But I have to tell you here. No its not.
What he Said is (for this part at least) correct.
Neither Wind nor Solar Energy is Capable of Delivering the Base Consumption.
Three Reasons for this.
1.
The Base Consumption Varies during the Day.
But Unlike Coal and Nuclear PowerPlants. You cannot just increase or decrease the Power on a Wind or Solar Power Plant.
You have to Build Extra Plants which then can be Activated and Deactivated to Deal with this.
Which is one Reason why these Sources are very very Inefficient and currently completely unable to Shoulder a Countries Power Supply without Coal or Nuclear Power Plants.
2.
The Energy you get from Wind and Solar is Heavily Dependent on the Weather. And if you used the most Modern Battery Technology currently available. You would need over a Billion Batteries to keep Germany Power for 1 Hour during the Day when Wind and Solar Power have too low Production to Supply the Net due to for example and Low Wind and Rainy Clouds. (The reason for this is because Wind Power needs a certain Speed to run. This must be neither too low nor too high. And Solar Power needs a Minimum Generation to actually Supply it into the Net. Which is often not reached on Dark Days. For example for the last Week here in Germany Solar Power would have been around 30-50% at best) And during Night it can very fast be 0%
Which means that assuming we have only 30% Power Usage during the Night. This would still require around 3 Billion Batteries to ONLY last this One Night.
And these need to be Loaded as well. Which means for this to Work you would require to Double the Installations again.
Ultimately. If you Include Maintenance and Shortages. You would need roughly 6 Times the Power Usage in Installed Power Plants using Wind and Solar Power. In Addition to that you would Require around 40 Billion Batteries to keep the Power Supply Steady and Available at all times.
This is currently impossible for Practical Means. And that leads to 3.
3.
Wind and Solar Power both need extensive Space. And they need more Space than they can Supply 24/7. Which Unfortunately results in them being used for Supply 24/7 being Impossible.
Nuclear Power by the way is and stays the most Efficient. This is a Fact and not Contested.
The Reason its no the best way is Solely due to the Nuclear Waste and the Danger of Accidents.
But in terms of Efficiency it is and stays the most Efficient.
Nuclear Power up to this Day. Is the Cheapest Possible Energy Source.
The Reason why Greenpeace says its not. Is because they include the Tax Money used to store Waste and other Stuff.
The thing is. They include this State Support into the Price of Nuclear Power and say its not as Cheap as they Tell you because the State helps out.
But they dont include this State Support which Wind and Solar Energy as well as others Receive. Because just so you know. Alot of the stuff used especially for Solar Panels is very hard to store as Waste as well.
Same for the Electronics in Wind Power. And they also dont tell you the heavy Subventions and how much Nature is Destroyed to get the Space to Build them. All of which is also heavily Supported by the State.
Sorry Mate.
Currently. And this is something I tell you because its the Field I come from. And also because I am an Electrician which actually had to Learn how Wind Power as well as Solar Power Works and how to Repair it etc etc.
It is not Possible to Run a Country Solely on Wind and Solar Power. You always need Fossil Power Plants which can be Regulated and which Carry 100% of the Load once the Green Power is not available due to Weather or whatever.
Its a Different Story for Small Countries like Iceland or Norway. Iceland thanks to Geothermal Energy which is Reliable can Run on such stuff. Norway thanks to its Extensive Cliff Coast can use Tidal Power for it.
But the Majority of Countries which does not have such special Terrain. Is not Capable of doing that.
And unfortunately we neither have enough such Terrain to have this work for the Entire World. Or even just the EU
I agree that this is a Problem.
But as I said before.
If we want to Fix it. We need to start Improving our Technology and stop wasting money by trying to Force Inefficient Technology onto the Stage.
If all the Subsidies Money Germany Wasted on Building Obsolete Wind and Solar Power Plants. Would have gone to Research of better Technology. I would assume that we would not require to even think about this Problem. Because long before 2040 when the Coal Mines in Germany start Closing. We would likely have the Required Technology on a Level where Companies would all by themselves Build and Use it. Because its more Cost Efficient than using Fossil Energy.
