Wired - Solar, Eclipsed 5-15min

Coal? Or the Sun? The power source India chooses may decide the fate of the entire planet. ... Already Earth’s fastest-growing major economy and its biggest weapons importer, India is on track to become the world’s most populous nation (probably by 2022), to have its biggest economy (possibly by 2048), and potentially to build its biggest military force (perhaps by 2040). What China was in the American imagination in the 1990s and 2000s, India will be in the next two decades—a cavalcade of superlatives, a focus of fears. ... officials and academics have long argued that Western nations are demanding that India industrialize without burning even a fraction of the fossil fuels that developed nations consumed when they industrialized. And Indians resent that Western nations insist on the right to judge Indian performance while refusing to help with the cost of transition. ... India’s demand for electricity is widely expected to double by 2030. …= Soon after being elected prime minister in 2014, he announced that India would produce 100 gigawatts of solar power by 2022 (the US now has about 20 gigawatts). ... To generate electricity from it, India plans to build 455 new coal-fired electric power plants, more than any other nation—indeed, more than the US now has. (India’s existing 148 plants, which provide two-thirds of its electricity, are among the world’s dirtiest and most inefficient.)

Back Channel - Canary in the Code Mine > 15min

As America switches from an industrial economy to a digital one, its bluest collar workers are facing the toughest challenge of their lives. Can miners really learn how to code? ... coal is basically over. The federal government has pumped nearly $23 million into the region in the last two years to diversify the post-coal economy and retrain miners into jobs like installing broadband fiber. But until there’s some serious new high-paying option, most ex-mine workers are getting by on unemployment, taking lower paying jobs, moving away, or, as one put it to me, “going into panic mode.” ... The job, they determined, would start with a 22-week training program to learn how to code. Trainees would be paid $15 an hour, which came from federal funds pumped through a regional economic development agency. That’s less than miner wages, but it was better than working at the McDonald’s double-lane drive-thru downtown. Then, after those 22 weeks, Justice and Parrish would put up three dollars for every one from the government and build a coding team that could take on real, paying work. ... Most had heard the program’s radio ad. “Have you been laid off from a job in the mining industry? If you are a logic-based thinker willing to work and learn new things, we have a career opportunity for you. BitSource is bringing the computer coding revolution to Eastern Kentucky.”

JP Morgan - A Brave New World: The De-Carbonization of Electricity Grids > 15min

A critical part of any analysis of high-renewable systems is the cost of backup thermal power and/or storage needed to meet demand during periods of low renewable generation. These costs are substantial; as a result, levelized costs of wind and solar are not the right tools to use in assessing the total cost of a high-renewable system ... High-renewable grids reduce CO2 emissions by 65%-70% in Germany and 55%-60% in California vs. the current grid. Reason: backup thermal capacity is idle for much of the year ... High-renewable grid costs per MWh are 1.9x the current system in Germany, and 1.5x in California. Costs fall to 1.6x in Germany and 1.2x in California assuming long-run “learning curve” declines in wind, solar and storage costs, higher nuclear plant costs and higher natural gas fuel costs ... The cost of time-shifting surplus renewable generation via storage has fallen, but its cost, intermittent utilization and energy loss result in higher per MWh system costs when it is added ... Balanced systems with nuclear power have lower estimated costs and CO2 emissions than high-renewable systems. However, there’s enormous uncertainty regarding the actual cost of nuclear power in the US and Europe, rendering balanced system assessments less reliable. Nuclear power is growing in Asia where plant costs are 20%-30% lower, but political, historical, economic, regulatory and cultural issues prevent these observations from being easily applied outside of Asia ... National/cross-border grid expansion, storing electricity in electric car batteries, demand management and renewable energy overbuilding are often mentioned as ways of reducing the cost of high-renewable systems. However, each relies to some extent on conjecture, insufficient empirical support and/or incomplete assessments of related costs
