[GWSG] 100% renewable US cities; Sky's Limit report; heat island tactics; transition birth pangs; UK tidal lagoons

[Tilley, Al]

1.  Pueblo, CO, and Moab, UT, are the 21st and 22nd US cities to commit to 100% renewable power.  The current high cost of power and the environmental effects of burning fossil fuels are two of the incentives.  http://www.climateactionprogramme.org/news/two_more_u.s._cities_to_go_100_renewable?utm_source=Feeds&utm_campaign=News&utm_medium=rss



2.  Last September Oil Change International in partnership with fourteen other organizations published a study showing that holding to the Paris targets of warming would mean no new fossil fuel development, and indeed would require that some stocks remain unused.  http://priceofoil.org/content/uploads/2016/09/OCI_the_skys_limit_2016_FINAL_2.pdf  A link to The Sky's Limit: Why the Paris Climate Goals Require a Managed Decline of Fossil Fuel Production:  http://priceofoil.org/2016/09/22/the-skys-limit-report/  Winifred Stephenson sends the item.



3.  Los Angeles plans to moderate rising temperatures a few degrees in the city through combinations of tree cover, cool roofs, and reflective pavement.  https://phys.org/news/2017-02-cool-city-world.html  Australian efforts to lessen the heat island effect in cities include green roofs and green pavements.  Increasing public transportation decreases the number of heat-producing cars, and management of air conditioning can reduce energy use and waste heat.  https://www.theguardian.com/sustainable-business/2017/feb/21/urban-heat-islands-cooling-things-down-with-trees-green-roads-and-fewer-cars



4.  Peter Sinclair puts together a Bloomberg video on the prospects of electric cars with articles on the solar ambitions of Saudi Arabia, declining oil jobs, and Trump's reckless and destabilizing threats to steal oil from the Mideast to suggest that the transition to renewable energy, while in process, is having a turbulent birth.  https://climatecrocks.com/2017/02/21/deniers-chase-oil-mirage-saudis-look-to-renewable-future/



5.  Tidal lagoons enclose tidal waters and use their flow to generate electricity with turbines.  They can be engineered and coordinated to produce steady power.  England's 320 mw Swansea Bay project is a pilot for a network of tidal lagoons which would produce up to a quarter of the country's electricity and serve as a model for other coastal areas.  Tidal power is now cheaper than nuclear and potentially even cheaper than wind, and the tidal lagoons are much longer lived than other power plants.   http://climatenewsnetwork.net/uk-tidal-project-spark-global-revolution/?utm_source=Climate+News+Network&utm_campaign=c6666ee2b7-EMAIL_CAMPAIGN_2017_02_22&utm_medium=email&utm_term=0_1198ea8936-c6666ee2b7-38803053  ?
