    1. Watch along as lead author Heymi Bahar & I launch IEA’s Renewables 2022 report and discuss the key findings ⬇️

      Video of key findings of IEA Renewables 2022 Report

    1. But 80% of the sector is already off fossil fuels. Our entire transport sector is fossil fuels. And that's actually the main challenge. But we've got a lot of heavy industry here like smelters and factories, and they're all 00:03:52 running on non fossils fuel energy. And so we can actually run an industrial sector without fossil fuels right now, which is amazing.

      Finland renewable energy stats: 80% is renewable transport sector is still dependent on fossil fuels heavy industry such as smelters and factories all run on renewables

    1. Die europäischen Produzenten von Windturbinen Mädchen enorme Verluste. Die Hauptgründe sind Kostensteigerungen und logistische Probleme. Hinzu kommen Investitionen für neue, stärkere Modelle und chinesische Konkurrenz. Ein zusätzliches Risiko könnte die Förderung der US-Turbinen-Industrie durch die Biden-Administration darstellen. Die europäischen Produzenten erwarten mehr Unterstützung durch die Regierungen, um Kompetenzen in Europa zu halten.

    1. Renewable energy critics argue that wind and solar are not reliable sources because of their variability. Others argue that wind farms encroach on pristine environment and destroy a country’s natural habitat, as is the case with the installation of thousands of wind turbines on scores of Greek islands in the Aegean Sea. How would you respond to such concerns, and are there ways around them?
    1. here are those same numbers compared 00:41:21 against reported global reserves so there's the amount of metal we need and there is the global reserves this column is the proportion of metals required to 00:41:33 phase out fossil fuels as a percentage that is of all the copper we need to make one generation of units current global reserves will get us 19.23 00:41:45 of the way there we don't have enough copper for one generation

      !- for : metals for energy transition - only have 19% of metals required for the first generation of phase out

    2. we used to have 500 years ago a small human system a big pile of natural resources and a small pollution plume 00:46:47 an industrial ecosystem of unprecedented size and complexity that took more than a century to build with support of the highest calorifically dense source of cheap energy the world has ever known that would be oil 00:46:59 in abundant quantities with easily available credit and unlimited mineral resources and now we've got a system that's a human system that's really large 00:47:10 a depleted natural resources [Music] portfolio compared to what we had but we've now got a massive pollution stream so now we seek to build an even more complex system with very expensive 00:47:24 energy a fragile finance system saturated in debt not enough minerals with an unprecedented number of human population embedded in a deteriorating environment 00:47:35 so at this point i'm going to say this is probably not going to go as planned

      !- key finding : green growth is not likely to be feasible - Simple diagram that illustrates the problem

    3. it also is summed together so everything we need is summed together per metal and that gives us this column here total metal required to produce one generation of technology units to phase 00:40:15 out fossil fuels and so that the that we've got these numbers here the next column is global metal production as it was from mining in 2019 00:40:28 so this is all from the usgs and the bgo the final column is how many years of production at the 2019 rate um would be needed to hit the actual 00:40:42 volumes needed so 2019's the last year before covert is the last year of stable data that's why i've used it so you might notice some of these numbers are rather large 00:40:55 like we will need seven thousand one hundred and one years of production to produce the needed number of volume of vanadium that's your uh your redox batteries

      !- for : metals for energy transition - unfeasible numbers

    4. the idea that we're going to do this in seven or eight years is very amusing so then the question is oh we'll just open more mines it's simple right

      !- for : metals for energy transition - not feasible

    5. assessment of extra capacity required of alternative energy electrical power systems to completely replace fossil fuels

    1. It’s clear that we need to make the switch to clean, reliable sources of renewable energy like solar and wind. Unlike fossil fuels, renewables don’t add greenhouse gases to our atmosphere.

      We need to change to renewable energy

    1. The local electricity linesmen, electricity inspectors, and other nodal officials in the electricity department also have key roles to play. Building their capacities to disseminate such information and handle consumer queries and concerns, and providing basic training in billing and metering for solar power can go a long way in improving consumers’ experience.

      Why will Discom want to disseminate the information when:

      1. They themselves don't understand how the system works
      2. They feel that rooftop solar will cut into their revenues? Here, instead of a top-down approach or bottom-up approach, RE generators and regulators need to have a 2 pronged synchronous approach to educate people about the technologies.

    1. The port’s nascent concentration of expertise creates opportunity to provide cost effective through-life engineering and logistics support in Thanet.

      Surprising that they make no reference to Richborough Energy Park and the transmission to the grid from there https://en.wikipedia.org/wiki/Richborough_Energy_Park Then there is the National Grid's Richborough Connection Project http://www.richboroughconnection.co.uk/

    1. LOPINOD is also being used to fund the development of a Low Carbon Plan. This plan will focus on the full spectrum of renewables including wind, solar, marine source heat pumps and tidal. It is hoped that we will become a hub for all green energy going forward, building on our existing involvement in the wind farm industry.

      Beachhead for solar, tidal, marine source heat pumps as well as wind energy
