It would be helpful if the science of climate tipping points gave clear answers to what temperature rise will trigger a runaway catastrophe: knowing that temperature rise X will cause calamity Y should focus everyone’s minds to do the right thing. But there’s simply not enough data for the science to do that, though it is clear that destabilisation is underway and major tipping points are approaching. That means we are in the danger zone, says … [Read more...]
Clean Trucks are coming: a review of battery, hydrogen, synthetic fuels and more
New EU fuel efficiency rules are forcing truck makers into a race to get their low emission vehicles onto the roads. From 2025, newly registered trucks must have 15% lower emissions, and from 2030 it’s 30%. Battery-electric drivetrains are most likely to dominate, assisted in their evolution by the assured progress and charging infrastructure of EVs. Hydrogen fuel cells and synthetic fuels are also in the game, though hindered by the inevitable … [Read more...]
The nexus between data centres, efficiency and renewables: a role model for the energy transition
How much will electricity consumption from data centres grow from today’s 1% of the global total? 40-fold by 2030? Or a more manageable 5-fold? Or less? Sean Ratka and Francisco Boshell at IRENA try to answer this question by looking at the innovations being made by the tech industry to drive down power costs and emissions. The evidence is promising. Though data centre computing output jumped 6- fold between 2010 and 2018, their energy … [Read more...]
