12 hours of energy storage enough for U.S. to run on 80% solar+wind – pv magazine USA

Scientists in California have modeled a solar-heavy/wind power electricity grid, without nationwide HVDC, that could reliably deliver 80% of U.S. electricity needs. 100% of needs would require 3 weeks of energy storage.

When it comes to scientific achievements, 2017 certainly left its mark.

From the use of ground-breaking gene-editing techniques that can potentially stop inherited diseases from taking root, to the creation of an artificial womb, here are a few of last year’s most important scientific milestones that could potentially change our future.

This is great read…

Last year a lot of people were asking if 2016 was the worst year ever. (It wasn’t.) I haven’t seen anyone making similar claims about 2017, but that doesn’t mean that this year didn’t produce its share of significant world events. It has. Below is my top ten, listed in descending order. You may want to read what follows closely. Several of these stories will continue into 2018.
