My take on renewable versus nuclear (ongoing post)
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. To replace 1 nuclear reactor of 1200 megawatt by 3.1 megawatt wind turbines, you'll need 1200 / 3.1 = 387 wind turbines, provided that the wind blows all the time. This is not the case, the average load factor across 100.000 wind turbines in the EU is merely 26%. So, a single wind turbine will only generate 3.1 * 0,26 = 0,8 MW. Also nuclear plants have a load factor, but higher at about 82,5%. All this taken into account, one would need 1228 wind turbines to replace 1 nuclear reactor. Source
- The lifespan of wind turbines is about 20 years, while nuclear is at least 60 years. This leads to enormous amounts of waste that at the present time is hard to recycle.
- Wind turbines release a toxic chemical named bisphenol A from eroding blades at a rate of 0.5 to 2.5 grams per year. Source
- The impact of wind turbines to the maritime ecosystem in huge and negative. Examples: Whale deaths,
