14. WRONG!!!

The same old misinformation from Kris. We now know that he has actually seen the page from the National Academy of Science study on energy that says that without storage technology, which we don't have; the maximum that "non-dispatchable" renewables like wind and solar can contribute is 20% of our needs.

If you more than 20% of non-backed up intermittent renewables; your electric grid is unstable. The best you can do with intermittent renewables is 20%, as long as you have 80% in dispatchable power sources like coal, nuclear, hydro, and gas to back them up.

But unless you have a storage technology; which we don't have at present; then the best renewables can do is 20%.

Hydropower gives us about 10%; so where do we get the other 70% with low carbon emissions? Nuclear is pretty much all you have.

We can have a low carbon, reliable system of 20% renewables, 10% hydro and 70% nuclear; but that's not "good enough" for the renewables crowd.
