    KWhrs from renewables. There are huge diminishing returns since few storage systems are being implemented outside of existing pump storage on existing hydros (all in Europe BTW) and all that new fossil to back up all that intermittent power.

    Germany is building coal plants to do this and Denmark has about reached it's limit on wind. You go either with natural gas or nuclear after that.

      I know it isn't popular here (some legit reasons, some unfounded, remember the right isn't the only ones liable to bad scinece) but frankly nuclear is more sustainable than other fossil fuels, and has much smaller carbon emissions. Now one thing to look into would be fuel cells, but I don't feel like going into detail with that at the moment. Storage isn't too big an issue with renewable energy sources, as most of their peak productivity hours are when we use the most energy in industry(exception being the morning and evening hours, when people wake up or go home). But you are right that it still has its limitations in lack of storage ability. Kinda funny how electrical energy has so many advantages, yet it's folly is the difficulty in storing it.
