Digging through my bookmarks and open tabs was interesting. The picture of the future that emerges: With costs for energy approaching the 1 cent range per kWh, electrical energy is going to be close to free. Money can and will be charged for guarantees, because batteries or other forms of storage still cost money.

  • Guardian: ‘Spectacular’ drop in renewable energy costs leads to record global boost »The new renewable energy capacity installed worldwide in 2016 was 161GW, a 10% rise on 2015 […] The new record capacity cost $242bn, a 23% reduction in investment compared to 2015, and renewables investment remained larger than for all fossil fuels. Subsidies for green energy, however, are still much lower than those for coal, oil and gas.«

  • Bloomberg: German Tenants Win Right to Generate Solar Power on Rented Roofs »Lawmakers are set to pass legislation dubbed “Tenant Power” on Thursday in Berlin. The bill promises owners of tenant blocks a subsidy of as much as 3.8 cents (4.3 U.S. cents) a kilowatt-hour for generating solar power on rooftops or from basement combined heat and power units.«

  • Forbes: The Cost Of Wind And Solar Intermittency »What is the integration threshold? There is no threshold, per se. The cost of managing intermittency is nonlinear and depends upon the mix and location of dispatchable and non-dispatchable sources, the match of local demand patterns with variable source pattern, and various other factors. Based on model studies of Germany and Indiana, Falko Ueckerdt found integration costs began to become significant at 20% [intermittent energy sources].«

  • Energiespeicher Blog: Unterirdische Pumpspeicher (Article in German) »Wie bereits mehrfach erwähnt, sind Pumpspeicher die verbreitetste Methode elektrische Energie in großer Menge abzuspeichern. […] Unterirdische Speicherkraftwerke sind von den Kosten nicht in einer anderen Welt als Batterien oder obertägige Pumpspeicher. Allerdings gibt es je nach Technologie erhebliche unterschiedliche technische Probleme und spezifische Kosten.«

  • New Shift: This is how Big Oil will die »And here is what is disruptive for Big Oil: Self-driving vehicles get to combine the capital savings from the improved lifetime of EVs, with the savings from eliminating the driver. The costs of electric self-driving cars will be so low, it will be cheaper to hail a ride than to drive the car you already own.« Using the math in the article, this will even be the case if the car is a traditional Taxi with driver, as long as it is electric and has the lifetime assumed in the article.The second half of the article discusses the US coal crash, which happened between 2011 and 2016 (the four largest US coal companies were worth about 45 bn USD together in 2011, and all bancrupt in 2016).
