    2018 UPDATE of my series about versus reality in solar PV Once again reality is steeply increasing and once again the IEA is having none of it Don't these guys ever learn? This has been going on since 2002 Seems their models simply can't conceive of exponential growth

    Reminder: Switching to EVs will save the UK £billions. A 2030 ban would save more money than a 2040 ban. (Analysis from CCC including cost of purchase, refuelling, charging point infrastructure, electricity generation & network expansion)

    Unintended consequence of the Fukushima disaster: Japan closed nuclear power plants, and now plans to build as many as 22 new coal-burning plants at a time when the world needs to slash carbon dioxide emissions to fight climate change.

    But the question is: what can contribute in the future? We examined global emission reduction potentials for UNEP. We found that the big six for 2030 are: -wind -solar -efficient appliances -efficient cars -afforestation -stopping deforestation , chapter 4

    And there you have it. One of the two hardest techs to convert to 100% renewables (when H2 from )-is being converted a decade early World’s first liquid H2 fuel cell cruise ship combines 3.2MW H2 with and will operate in 2023

    If you ever wondered wether policies promoting electric vehicles could work and lower CO2 emissions, this is an interesting graph.

    As someone who has been defending against stories of imminent bankruptcy from shills like for years and years... I would like to go on record to say this is madness too. (Imho of course and this is not investment advice.)

    Excellent piece in Nature this week covering our recent paper on evaluating climate model performance. We found that 14 of 17 climate model projections published between 1970 and 2001 accurately projected future warming:

    74.8% renewable energies in German electricity generation on Saturday, 01.02.2020, and the grid remained stable. Super performance of our four transmission system operators , , and ! Thanks a lot.

    1. This is an obvious prediction, but I want to get it on record. The GOP just released Trump from any accountability for trying to cheat in the upcoming election. That's one sign of many that they are going to try to rig the election, in a range of illegal & semi-legal ways.

    Replacing [energy source x] with [energy carrier y] is not a valid substitution. This fallacy pops up to many times! Continues partially on transport (which uses oil instead of nuclear and coal). This is poor energy journalism.

    This is significant. It’s good to see more and more financial signals, and shifts in business leadership, on climate change. Let’s see much more.

    ‘It turns out that when the wind don’t blow and the sun don’t shine, we’re going to be fine.’ Pretty catchy sound bite that! Excellent piece by .⁦⁩ presenting that old fashioned thing-factual information-about need for more gas.

    What’s most fascinating with the claims about batteries CO2 impact is not that most LCA’s rely on out-of-date secondary data but that they’re so sticky among people who previously never cared about CO2 emissions at all and who usually deny that they have an effect on the climate.
