This is entirely my point that proponts of renewables refuse to see, it doesnt scale in a linear fashon. Lets talk wind turbines because they are the most cost effective and realistic of the group. Wind turbines generate power on a cubic function of wind speed, that means if you double the wind speed you get 8X (yes I will say it again EIGHT TIMES) the power. Also wind turbines have a minimum windspeed before they start to turn. Turbines also have a max wind speed after which they shut down to prevent damage to themselves. So based on this there is a huge variability in power production and when wind is having a poor day, some other source must be there to pick up the slack. In addition to this, it is totally impossible to forcast forward any significant time period. Right now conventional powerplants do not run at peak rated power so it is not a problem but as renewables grab a larger share of the capacity on the grid they overcome that reserve that the reliables are holding.
