Renewables and present battery technology are just not going to get Europe anywhere close to energy self-sufficient . . . and freedom from Russian energy. From Daniel Lacalle at mises.org:
Europe is not going to achieve a competitive energy transition with the current interventionist policies. Europe does not depend on Russian gas due to a coincidence, but because of a chain of mistaken policies: banning nuclear in Germany, prohibiting the development of domestic natural gas resources throughout the European Union, added to a massive and expensive renewable rollout without building a reliable backup.
Solar and wind do not reduce dependency on Russian natural gas. They are necessary but volatile and intermittent. They need backup from nuclear, hydro, and natural gas for security of energy supply. Dependency on these backup sources rises in periods of low wind and little sun, just when prices are highest.
“Solar goes to zero for twelve hours a day, and that is guaranteed. The wind blows sometimes, and sometimes it does not, also guaranteed. They both depend on weather, which is 100% out of human control. They are on their best day a supplement,” wrote a Navy pilot follower.
