This study ambitiously tries to estimate the benefits from emissions that were avoided because of the increase in wind and solar energy from 2007 through 2015, and to do so for the whole of the U.S. Millstein and colleagues looked at carbon emissions, as well as sulphur dioxides, nitrogen oxides, and particulate matter, all of which contribute to poor air quality. There are other factors that also need to be considered. A rise in renewables isn't the only thing that has been changing in the energy sector: fuel costs and regulation have also played a role. How much of the benefit can be attributed to wind and solar power, and how much to other changes? The researchers used models that track the benefits attributable to renewable power as a proportion of the total reduction in emissions.
Finally, Parental Control features are being overhauled in favor of what Sony calls "Family on PSN." This replaces the old Master/Sub account system; instead, one user is deemed the Family Manager, and they can set up other accounts and appoint them as a Parent/Guardian, Adult, or Child. Parents or Guardians can restrict Child accounts in their "use of online features and communication with other players, set restrictions for games, restrict the use of the internet browser, and set spending limits for PlayStation Store." Note that Sony says the first time any North American user tries to set up an Adult account, they will be charged $0.50 "to verify that you are an adult."
