Lots of sunlight, but limited amounts of manufacturing and rare earth metals for solar and limited amounts of energy storage for times when solar and wind aren't available. Solar and Wind are terrific, but they're not a free lunch. What drives down the price of energy, drives up the cost of wind/solar/batteries.

When you double battery production over 5 years prices go down not up. It’s a function of economies of scale.

It’s one of the major reasons EV ranges keep increasing the batteries are less expensive.
