Wind and solar power have limited practical use in the modern world. Most people don't live where the wind blows all the time. See Wyoming, USA and Patagonia, Argentina. The sun doesn't shine all the time. Battery backup for billions of people doesn't work.

Lightwater nuclear power uses lightly enriched uranium. Heavywater nuclear power uses non-enriched uranium. They are the cleanest, safest source of generating electricity. Anti-nuclear fear-mongers have worked without stop in the free world to stop this technology. China, India and Russia ignore the fear mongers.

Hydroelectric power is clean and renewable. It is a major source of energy for Austria, Canada, China, New Zealand, Switzerland, Uruguay and the USA. Dam failures are a potential hazard. Dam sedimentation filll up is a problem.

Fossil fuels (coal, oil, and natural gas) and their 6,000 by-products created the wonderful modern worlld since 1800. Living standards improved, food supply grew, population has increased from 1 billion to 8 billion.
