For those deeply interested in our future energy system and how it will evolve, I highly recommend two in-depth papers published in the last year. Here I will show a similar vision step-by-step using some of the same assumptions and publicly available data using “back of the envelope calculations” (spreadsheets)

I would love to have 100% clean electricity by 2035. Such a goal is admirable for its audacity and for its ability to get people motivated. For that I applaud it. But when we get down to it, will it be smart policy? Could it be that 90% would provide greater carbon savings than 100%?

Intermittency is the one factor holding back large-scale adoption of renewable energy. Are Super Grids that span continents the answer, and at what cost?

One wonky court decision might have just unlocked America's renewable energy future by requiring regional coordination between states and utilities.

New research from Stanford University suggests the high energy requirements of grid-scale batteries make energy storage a good option for solar energy, but not wind farms.

The National Center for Atmospheric Research (NCAR) is adding to its already impressive list of renewable energy innovations with a new two-year plan to develop custom forecasting systems for wind and solar generation.
NCAR scientists and engineers will develop technology to predict sudden changes in wind speed, enable wind farm operators to curtail turbines before potentially damaging icy conditions, and predict the amount of energy generated by small-scale solar panel installations

Intermittency may be the Achilles Heel of solar energy. Since the Sun doesn’t always shine and utility-scale energy storage isn’t available yet, grid operators have to rely on dispatchable generation like natural gas or when clouds cover up solar farms. But that may be about to change in a big way

Following up on a great guest post by Chris Varrone on wind intermittency and why it's not a big deal, apparently the International Energy Agency (IEA) now has a new book out, Harnessing Variable Renewables: a Guide to the Balancing Challenge, that tells us the same thing that Chris was explaining
