QUICK NEWS, April 11: Climate Change Is Not Fair Weather; More New Energy For The Buck; Tracking The Falling Cost Of Small Solar-Plus-Storage
Climate Change Is Not Fair Weather Climate Change Is Hitting Home, And It's Not Fair
Heather Goldstone, April 10, 2017 (The Point)
“Surveys consistently show that a majority of Americans think climate change is happening, but that it won’t affect them. Scientists say otherwise. Researchers already are seeing impacts - often dramatic, sometimes counterintuitive - on both natural systems and human communities. And, while everyone will be affected, some will be hit sooner and harder…While there may be winners and losers in the natural world, it's hard to argue that any people will win when it comes climate change. But there are dramatic racial and socioeconomic disparities in the impacts of pollution and climate change, with the poorest and most vulnerable hit hardest…All told, the climate change story is not a happy one…[T]he harsh unfairness of it can be overwhelming…” click here for more
More New Energy For The Buck The world spent less money to add more renewable energy than ever in 2016; $241.6 billion in investment gets you 138.5 gigawatts of renewable energy
Megan Geuss, April 10, 2017 (Ars Technica)
“…[Investors spent less money in 2016 to add more renewable energy capacity than in any previous year. In total, [they] only spent about $241.6 billion in renewable energy investments in 2016, down 23 percent from 2015…[but it added 138.5 GW of capacity in] wind, solar, biomass, and waste-to-energy, geothermal, small hydro, and marine sources like wave and tidal energy]…That represents a nine percent increase year-over-year from the 127.5 gigawatts added in 2015…[The falling investment but rising capacity] reflects the plummeting prices of certain kinds of renewable energy, especially solar photovoltaic panels and wind installations…[T]hat’s a good thing for reducing pollution that contributes to climate change…[T]he proportion of global energy derived from renewable sources rose from 10.3 percent to 11.3 percent year-over-year [according to the study]…” click here for more
Tracking The Falling Cost Of Small Solar-Plus-Storage NREL study aims to fill gaps in residential energy storage cost benchmarking Andy Colthorpe, April 7, 2017 (Energy Storage News)
“…[Data from Q1 2016 on a 5.6kW PV array with a 3kW/6kWh lithium-ion battery and a 5kW/20kWh lithium battery with the same size PV array shows that] a DC-coupled ‘small battery’ system could cost US$27,703, while an AC-coupled could cost US$29,568 on a new installation where solar and battery were installed together…[R]etrofitting, which is more commonly associated with AC-coupled systems, to an existing PV system raises the installed price to US$32,786…[A] ‘large battery’, DC-coupled, could cost US$45,237 - significantly more than the ‘small battery’ systems. The AC-coupled version of that would be US$47,171. Part of the higher cost consists of need for more, and bigger, inverters [according to a new study from Lawrence Berkeley National Laboratory. It assumes the systems] are used for PV optimisation purposes to boost self-consumption, including peak demand shifting and time-of-use shifting, but one obviously offers the more robust backup solution…” click here for more
