        • Report Finds 76 Solutions Available Right Now to Slow Down Climate Change

          I have the Drawdown book. It's more like an encyclopedia than text, in that it simply reviews 110 actions that would result in reduced CO2 equivalent emissions. "Actions" rather than pure technologies as, for example, educating women and reducing extreme poverty are included, as both have direct impacts on child mortality and fertility rates. The interesting thing is that, based on their models and calculations, virtually all of the actions are what they describe as "no regret" actions in that they result in more money saved/generated than their cost.

                    • The $2.5 Trillion Reason We Can’t Rely on Batteries to Clean up the Grid

                      Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role.

                      MIT Technology Review |
                      • James Temple
                      ...
                      The 300-megawatt facility is one of four giant lithium-ion storage projects that Pacific Gas and Electric, California’s largest utility, asked the California Public Utilities Commission to approve in late June 2018. Collectively, they would add enough storage capacity to the grid to supply about 2,700 homes for a month (or to store about .0009 percent of the electricity the state uses each year).

                      The California projects are among a growing number of efforts around the world, including Tesla’s 100-megawatt battery array in South Australia, to build ever larger lithium-ion storage systems as prices decline and renewable generation increases. They’re fueling growing optimism that these giant batteries will allow wind and solar power to displace a growing share of fossil-fuel plants.

                      But there’s a problem with this rosy scenario. These batteries are far too expensive and don’t last nearly long enough, limiting the role they can play on the grid, experts say. If we plan to rely on them for massive amounts of storage as more renewables come online—rather than turning to a broader mix of low-carbon sources like nuclear and natural gas with carbon capture technology—we could be headed down a dangerously unaffordable path.
                      ...
                      This peaker role is precisely the one that most of the new and forthcoming lithium-ion battery projects are designed to fill. Indeed, the California storage projects could eventually replace three natural-gas facilities in the region, two of which are peaker plants.

                      But much beyond this role, batteries run into real problems. The authors of the 2016 study found steeply diminishing returns when a lot of battery storage is added to the grid. They concluded that coupling battery storage with renewable plants is a “weak substitute” for large, flexible coal or natural-gas combined-cycle plants, the type that can be tapped at any time, run continuously, and vary output levels to meet shifting demand throughout the day.

                      Not only is lithium-ion technology too expensive for this role, but limited battery life means it’s not well suited to filling gaps during the days, weeks, and even months when wind and solar generation flags.

                      This problem is particularly acute in California, where both wind and solar fall off precipitously during the fall and winter months.

                      This leads to a critical problem: when renewables reach high levels on the grid, you need far, far more wind and solar plants to crank out enough excess power during peak times to keep the grid operating through those long seasonal dips, says Jesse Jenkins, a coauthor of the study and an energy systems researcher. That, in turn, requires banks upon banks of batteries that can store it all away until it’s needed.

                      And that ends up being astronomically expensive.
                      ...
                      The Clean Air Task Force, a Boston-based energy policy think tank, found that reaching the 80 percent mark for renewables in California would mean massive amounts of surplus generation during the summer months, requiring 9.6 million megawatt-hours of energy storage. Achieving 100 percent would require 36.3 million.

                      The state currently has 150,000 megawatt-hours of energy storage in total. (That’s mainly pumped hydroelectric storage, with a small share of batteries.)
                      ...
                      Building the level of renewable generation and storage necessary to reach the state’s goals would drive up costs exponentially, from $49 per megawatt-hour of generation at 50 percent to $1,612 at 100 percent.

                      And that's assuming lithium-ion batteries will cost roughly a third what they do now.

                      • Oregon voters have overwhelmingly rejected this sort of thing in recent past. Governor Brown's questionable executive action will likely create many court cases, deflecting taxpayers dollars for "her defense"; meanwhile it reflects the basic ignorance of science and economics that drives the phoney shame of ACC/AGW and will actually make the future economy and environment worse for the future generations.

                        Next on her agenda, an executive order telling the tides to stop flowing and the Sun to never set.

                              • Meanwhile, the case for "human caused" versus the record of Natural Cause of the past four billion years remains unproved; as does the case that current amount of CO2, at 0.04% of dry atmosphere content, is the driver of change when it hasn't been such for the past four billion+ years.
