by definition "exponential" implies a "continual rate reduction" ..ie, each year the reduction in cost is less than the previous year....such that effectively the cost will eventually reach a "floor" and drop no further.I've been saying on this forum for years that batteries and solar are on an exponential decline, and that by 2025 solar + batteries will be cheaper than anything else for energy. Probably sooner.
I seriously want to know if you have any evidence to support the idea that batteries and solar will not continue to decline exponentially in price, and if so what that evidence is.
What level that floor is , is the question ?....its going to be dictated by factors like cost of materials, labour, manufacturing and transport costs , etc etc.
The graphs i have seen for pv panel cost, suggest that the "floor" is nearly there at about $0.5/W.
All the low hanging fruit has been harvested !
FYI... This year alone, there have been 17 new papers published in Scientific journals that prove CO2 is not, and cannot be, a GHG. !!
