The media and the public appears to have confused the Green Party’s platform calling for 100% renewable energy by 2030 with the goals in the Joint Resolution for a Green New Deal introduced by Senator Edward Markey (D-MA) and Representative Alexandria Ocasio-Cortez (D-NY). The Joint Resolution calls for a “10-year national mobilization,” but contains no deadlines other than zero greenhouse-gas emissions by 2050, which is 30+ years from now. Given that we went from horse and buggies and wood stoves to widespread automobile use and electrification in 30 years at the beginning of the twentieth century, such a transformation doesn’t seem imposing.
Evidence of how job training is lagging behind job needs. The U.S. Labor Department reported 7.3 million openings, but only 6.3 million people were actively seeking jobs and unemployed. Employers are not able to find the technically-trained individuals that they need for the changing economy. Only a small portion of this shortfall can be met through training in our standard educational institutions. We should be looking for other retraining solutions such as those in Europe.
The analogy to Netflix is fascinating. As GTM points out, Netflix started out competing with Blockbuster in video DVDs, but then spilled over into video streaming (BTW, a market that Enron famously thought it could corner in the last 1990s.) So Netflix is now competing with both cable and broadcast companies. One can see how renewables could jump out of just electric service to building space conditioning and water heating, and vehicle fueling. Tesla is already developing those options.

I’ve been struck by the lack of panic in the energy industry about President Trump’s decision. This article goes into that underlying confidence that the momentum appears unstoppable.
WASHINGTON — President Trump’s decision to abandon the Paris Accord will slow the battle against climate change in the U.S., but there’s too much momentum in the nation’s clean-energy economy to shut it down, energy experts say.

The recent jobs report may be indicating that any additional stimulus such as tax cuts or infrastructure investment will be ineffectual, or even counterproductive.
A new study in Nature Energy finds storing rooftop solar can increase emissions and energy consumption.
My thoughts: Here’s the key statement for the finding in this report: “based on today’s Texas grid mix, which is primarily made up of fossil fuels.” If the either the marginal generation on the grid is low or no GHG (e.g., renewables overgeneration which is an increasing problem in California) or the connection to the grid is cut or restricted (e.g., in a microgrid), then this premise doesn’t hold.
This study relies on fossil fueled generation being the marginal energy source. It also focuses solely on operational changes with existing resources. The appropriate frame is looking at the change in generation investment with and without storage, so for example more renewables become cost effective with storage so the overall generation mix changes.
The second problem is that most of the production cost models are yet incapable of capturing reduction in flexible capacity use. That’s why the California Energy Commission has had DNV and LBNL working on modeling those resources. So the emission savings are underestimated.
The third problem is that savings in residual unit commitment (RUC) is underestimated in the models. These are gas units running on standby with no-load, to be available the next day for ramping, load following or reliability. Storage reduces the need for these resources as well. NREL recently released a study on the value of storage that captures this benefit.
If these findings are valid, then the existing Helms pumped storage plant is also increasing GHG emissions. One could go so far as to say that the value of pondage hydropower storage may be so diminished that relicensing conditions that require run of river operations may have little effect on costs and GHG emissions.
