2035: Clean Grid 90%, Electrify 50%

September 22nd, 2020 | by Brad Rouse

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)

100% By 2035? 90% Might Be Better: Consider The Opportunity Costs

August 31st, 2020 | by Brad Rouse

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%? 

Breakthrough Renewable Energy Forecasting Coming To US Grid By 2015

May 10th, 2013 | by Silvio Marcacci

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

Solar Energy Forecasts Could Boost Industry Outlook

February 28th, 2013 | by Silvio Marcacci

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

IEA: Wind and Solar Intermittency NOT a Big Deal!

June 1st, 2011 | by Zachary Shahan

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
