Carbon Tracker, in its latest report, envisions a scenario in which 2 million barrels per day of global crude oil demand are erased by 2025 because of the penetration of electric vehicles in the transportation sector. 2 million b/d is equivalent to the supply overhang that triggered the 2014 crude oil price meltdown. The report suggests total […]

In 2015 humans used about 575 quadrillion Btu (British thermal units) of energy, according to the US Energy Information Administration. (575 followed by 15 zeros; a Btu is roughly the energy released in a single match.) With a global population of 7.3 billion, that worked out to 78 million Btu per person that year. Nearly 40% of all […]

Almost all Costa Rica’s electricity was produced by renewable energy in 2016. The Costa Rican Electricity Institute reported that around 98.1% of the Central American’s country’s electricity came from renewable sources. The electricity was generated by hydropower facilities, geothermal plants, wind turbines, solar panels and biomass plants. As much as 1.8 gigawatts of new energy storage — mostly from lithium-ion batteries — […]

MIT Technology Review has an article about robots mining 24 hours a day. Mining companies are rolling out autonomous trucks, drills, and trains, which will boost efficiency but also reduce the need for human employees. Mining companies are well placed to expand automation rapidly, because they have already invested in centralized control systems that use software […]

The city of New York’s Christmas holiday-light energy use has declined by about one-third from 2010, largely due to the switch to LEDs (light-emitting diodes).  This year, holiday lighting in the US city will add about 750 megawatts of load, down from about 1,150 MW in 2010. Investment Bank Goldman Sachs calls LEDs one of the fastest technology shifts […]

Switzerland voting in a referendum rejected a proposal to introduce a strict timetable for phasing out nuclear power. A majority of cantons (Swiss states) voted against the initiative with the latest reports showing the breakdown 55% to 45%. The plan would have meant closing three of Switzerland’s five nuclear plants next year, with the last shutting in […]

The International Energy Agency said government support and lower generation costs will lead to stronger than-expected global growth in renewable energy over the next five years. The agency said it anticipates global renewable electricity capacity will grow by 825 gigawatts by 2021, a 42% increase over last year. By that time hydro, solar, wind and other […]

The US Energy Information Administration estimates that global crude oil demand will grow from 94.8 million barrels a day this year to 105.3 million barrels in 2026. With world oil prices now hovering around $50 a barrel and little exploration going on, there is concern in some quarters that this demand will not be met.  Only 2.7 […]
