It does not produce immediate benefits, but perhaps a problem that is 100 years in the making might take a global solution on a 100 year time scale.
Electricity is expensive
If you had a 100km*100km grid of easily maintained solar panels already manufactured and in operation, electricity is generated _without expense or by-products_ Batteries and electric power have bad by products:
1. heat generation
2. by-products of manufacturing
3. electricity generation by-products
Complete nonsense. We have 8 billion people driving cars that are decimating our air quality and have already drove the carbon cycle so many standard deviations from the mean levels in pre-industrial society that I am doomed to live on a scorched, dead earth. The negative effects of battery creation and usage are infinitesimal in comparison.
