Kelantan, Kedah dan lain² perlu manfaatkn musim kering utk tanam pokok (cepat tumbuh); bina & dalamkan kolam baru/sedia ada. Yg hampir sungai, alihkan sebahagian ke kolam berhampiran.

Today and tomorrow, @G7 #Energy ministers meet in #Japan – a country, often considered a “laggard” on #energytransition. What is 🇯🇵’s energy system like and why is it so reluctant to step up #decarbonisation of its economy? A 🧵 1/19

The “usual” arguments by the 🇯🇵 government when confronted with lack of both action and ambition on #energytransition:
1. #Japan is resource-poor
2. Japan’s geography limits #renewables build-out
3. Technologies & Innovation will solve the transition
How true are they? 2/19

Japan is indeed poor in some resources, most notably #fossilfuels. Fossil fuel based, its energy system is 88% dependent on #oil, #LNG and #coal imports. It has one of the least self-sufficient energy systems, dependent on #oil & gas from #MiddleEast & #coal from #Australia. 3/19
3 confessions from #ClimateActivists & #ClimateEconomists seeking to tackle the #ClimateCrisis
We were wrong
-2 promise apple pie & motherhood sans costs
-2 repeat solar PV cheapest form of power sans caveats
-2 dismiss any trade-off between climate & development

Back in the day those, including me, who worked on many different versions of the #greendeal all focused on the win-win scenarios ... #greenjobs #greengrowth #justtransition etc. and tho the context has changed completely this win-win farming remains even in the year 2023
Had we mobilised on a war-footing back then, invested at scale, imposed #carbontaxes, innovated like mad & massively increased financial & technological support 4 developing economies to shun coal & adopt #renewables, the #greendeal may have worked, albeit not without real costs
#Climate needs #electrification AND #hydrogen.
Both compete for #renewableelectricity, policy and infrastructure support. Policy makers have to take decisions, secure expectations, avoid further fossil lock-in
Our paper offers guidance.

#efuels(right) replace fossils without the end-use transformation required by (direct) #electrification(left)
This promises to make combustion technologies and fossil infrastructure part of the climate solution;
yet, shifting the burden to the supply side has limitations…

#Efuels require 2 – 14 times more (renewable) electricity than a direct #electrification (e.g. electric cars are five times more efficient)
Remember, (growing) renewable power capacity is far from fully meeting only today’s electricity demand.
(no regret: #renewableexpansion)

Out in @NatureClimate: We compiled 1,550 scenarios of #solarpv from peer-reviewed and influential grey literature and showed that uncertainty in global PV capacity by 2050 is largely associated with who, when and how created the scenarios

Over the past decade, scenarios projected values of #solarPV generation in 2050 from nearly zero to above 300 EJ yr−1, equivalent to capacity exceeding 60 TW
Final commissioning today by Darren from Vaillant @mark_vaillant for this #heatpump #solarpv setup. Few walkthrough videos...
This is the outdoor unit on its gravel base and fridge pipework boxed in along the fence through the garden. #heatpump
This is the pipework, indoor unit and buffer in a big cupboard in the hall. Should have hoovered up first, though 😉
