I was an early investor in renewable energy, with our own solar panels and an energy contract with a cooperative Belgian energy company that provides 100% renewable electricity. While I believe that each kWh generated with non-fossil sources is a good thing, I am increasingly convinced that nuclear energy is the best long-term solution to the world's energy needs. Renewable energy has fundamental flaws, such as its intermittency and the need for large amounts of land, which make it difficult to scale up to meet global demand. Nuclear energy, on the other hand, is a reliable and scalable source of energy that does not produce greenhouse gases. some of the issues with renewables that I consider to be fundamental flaws Need for large amounts of land and sea .

This is not the case, the average load factor across 100.000 ...
