QUICK NEWS, June 20: What Power Mix Will Beat Climate Change (Part 1)?; What Power Mix Will Beat Climate Change (Part 2)?; New Energy Is NO Threat To U.S. Grid
What Power Mix Will Beat Climate Change (Part 1)? 'Full toolbox' needed to solve the climate change problem
19 June 2017 (Carnegie Instituion for Science via EurekAlert)
“Solving the climate change problem means transitioning to an energy system that emits little or no greenhouse gases into the atmosphere…[but making the transition will depend on making use of energy technologies such as bioenergy, nuclear energy, and carbon capture technology, according to a new] study from a group of 21 published by the Proceedings of the National Academy of Sciences…[Wind, solar, and hydroelectric should play a central role in future American energy systems but they] concluded that a much broader array of energy technologies is necessary to transition to a zero-emissions future as quickly and seamlessly as possible…The team is particularly concerned about having backup energy sources to deal with variability in solar and wind, because current energy storage technology is not sufficient to cover gaps in production on a national scale…Careful evaluations of energy system transitions consistently show that broader portfolios form an important base to ensure success…” click here for more
What Power Mix Will Beat Climate Change (Part 2)? 4 Reasons Nuclear and Fossil Fuel Supporters Criticizing 100% Renewable Energy Plan Are Wrong
Mark Jacobson, June 19, 2017 (EcoWatch)
"…[The Proceedings of the National Academy of Sciences paper arguing a 100% New Energy mix from wind, solar, and hydroelectric powers will threaten reliability] is replete with false information…[It claims] nuclear, fossils with carbon capture and biofuels reduce costs of decarbonization…[but an independent assessment of our 100 percent wind, water and solar plans] concludes neither fossil fuels with CCS or nuclear power enters the least-cost, low-carbon portfolio…[It claims we propose technologies that can't be scaled up…[but underground thermal energy storage in rocks, hydrogen fuel cells, and demand response are proven technologies now in use. It also claims we made modeling errors but multiple data sets show] this is absolutely false…[Finally, it claims our climate model] has never been adequately evaluated…[but it has been used in] 11 published multi-model inter-comparisons and 20 published evaluations…[a 2008 Atmospheric Physics and Chemistry Journal comprehensive review concluded it] is ‘the first fully-coupled online model in the history that accounts for all major feedbacks among major atmospheric processes based on first principles’ and hundreds of processes in it still not in any other model…” click here for more
New Energy Is NO Threat To U.S, Grid No evidence that changing power mix endangers electric system reliability; Expert report by Analysis Group finds that low-priced natural gas, not renewable energy policies, is fundamental cause of coal and nuclear plant closures
June 20, 2017 (American Wind Energy Association)
“…[Market forces, primarily low-cost natural gas and flat demand for electricity, are] causing some coal and nuclear power plants to retire, and not state and federal policies supporting renewable energy development…[and] the changing electricity resource mix poses no threat to reliability of the nation’s power system [according to Electricity Markets, Reliability and the Evolving U.S. Power System from the Analysis Group, which is intended] to answer independently the questions raised recently by Energy Department Secretary Rick Perry…Factors such as rapid growth in deployment of advanced energy technologies, and state policies supporting such technologies also contribute to reducing the profitability of less economic assets, but such factors are secondary to market fundamentals…[In addition, the] retirement of aging resources is a natural element of efficient and competitive market forces…Many advanced energy technologies can and do provide reliability benefits…Given the many attributes associated with a reliable electric system, the term ‘baseload resources’ is an outdated term in today’s electric system…” click here for more
