In your analysis, have you included the required base-load generation systems required when renewables aren't generating (night time, no wind) or the required storage systems (which actually don't exist) to time shift the energy supply?
- threeseed 7y agoActually the storage systems do exist. There are batteries, hydro etc. And many of the bids for power projects are including batteries as well.

- gwright 7y agoIt depends on what period of time you are trying to cover for. Yes there are solutions today that work for short periods of time, but as renewables increase as a percentage of generation capacity, the more storage you need. Grid-level battery storage for large periods of time is unproven and crazy expensive if you just extrapolate from smaller solutions.
- coredog64 7y agoI would add that as renewables get cheaper, there will also come a point at which that will also lower the price of fossil fuels. At present, demand for fossil fuels exceeds supply. If/when renewables cover that demand, the demand portion of the price will fall.
