Wednesday links: the end of coal, clean power mandates, the Great Wall of Chinese EV charging stations, monster turbines, PV systems for developing countries

• The world’s biggest coal miner, BHT, sees the end of the coal era on the horizon.
• Interesting piece on why, in the 29 states with clean electricity policies, those policies are working. Specifically, the author makes the argument that the increase in renewable capacity and affordability in the US can be partially attributed to standards requiring a certain share of power retail come from clean sources. According to the article, 10 states mandate at least half of electricity sales come from these sources, with enforceable penalties for utilities that do not meet that benchmark. 
• A glimpse of the unbelievable scale of electrification in China:

Shenzhen's Minle #EV #charging station becomes the world's largest as Southern Power Grid adds another 172 fast chargers.#BYD, SPG & #Potevio operate 637 fast charger station that can service close to 5 K vehicles per day.
On average, It charges 160 MWh per day. pic.twitter.com/5rYke5FBgK

• The newest wind turbines have blades longer than football fields. The author paints an extremely rosy picture of their potential in offshore applications.
• IRENA, partnered with the Abu Dhabi Fund for Development, are installing PV systems on the rooftops of 10,000 low-income households in developing countries. Cool stuff.
