WWS also creates 25 mil more jobs than lost, uses less land & results in much less mining
Lower costs, better health, better climate, more jobs, less land, less mining, more energy security. No downside

Why a Transition to 100% Wind-Water-Solar Improves Your Life
It reduces world energy costs by $10t/y in 2050. Since upfront cost is $60 t -> 6 y payback time
Also saves $30 t/y in health costs & $30 t/y in climate costs, so total savings $70t/y -> 1 y payback

From the last graph, it is clear that WindWaterSolar follows load (demand) seasonally far better than does a baseload (flat) electricity source such as nuclear or coal.
Every day is a new record.
Two more 100% WindWaterSolar days for part of the day in CA, making it 213 100% days so far in 2025.
CA will be 100% WWS 24/7/365 by 2037.
PV and batteries are replacing gas rapidly.
Gas down 18% versus 2024 and 37.4% versus 2023.
