I can agree with 1. and 2. Regarding energy storage, we could build more Pumped-storage hydroelectricity (PSH), like the one in Żarnowiec. Battery storage as part of the system is too expensive and has too short a lifespan - it would be throwing money down the drain. "Green" technologies in Polish conditions are simply sabotage, as my professor called it during lectures on the subject "Energy and the Environment" at the University of Technology (in 2002, just before green scam started). However, we need investments in coal technologies more than nuclear power plants, because we have old power plants, and technology in this area has made enormous progress. We could have even 50% more energy from the same amount of coal burned. And without coal our system will collapse.
