Wind and Solar Start To Hit Primary US Energy Demand |
"As wind and solar grow globally, primary demand itself will see its growth halted through the harvesting of thermodynamic savings. Work and processes will continue to migrate away from combustion, and its enormous heat loss. Large transit services like LA Metro will increasingly run trains and buses off a powergrid that is rapidly adding cheap wind and solar.

It took about five years for wind and solar to advance from below 1% of US electricity to nearly 3%; and then another 5 years to advance towards 7%, last year. Wind and solar will easily reach 10% of US electricity by 2020. Now, it appears wind and solar will trace out a similar path in US primary energy demand: 2.77% last year, likely 7% by 2021, and 10% before 2025. When people complain that rate isn’t fast enough, here is a question: what is your model for the rate of plausible, systemic change?"

Electric Vehicles: Climate Saviors, or Not? | Issues in Science and Technology
"Even in relatively clean states, such as California, the difference in CO2 emissions from nighttime to daytime can be significant. The nighttime start-up of coal plants in response to the additional electricity load from EVs increases marginal emissions. And, of course, clean solar energy is not available at night. As one study has explicitly stated, there is a “fundamental tension between electricity load management and environmental goals.”"

GE targeting $1B cost cut in Power unit, sale of Baker Hughes (SNL)
GE Power - overcapacity. $1B cost cuts, 45% less capex in 2018. Were wrongly expecting PJM capacity mkt to justify upgrades. To focus on cash & LT contracts - renewables. "renewables and storage ... a mega-trend ... The challenge ... is really the margin rate. This is an intensely price competitive industry ..."
