some numbers what it means to tripple renewables
along with tripling renewables, there is the desire to reduce energy consumption and foster electrification. This is especially important in the building and transport sector. To achieve the set goals we need to e.g. double building renovation rate, have 10x more smart meters, 10x more heat pumps and 30x EVs

Mary Robinson: “I read that your company is investing in a lot more fossil fuel in the future.” Al Jaber responded: “You’re reading your own media, which is biased and wrong. I am telling you I am the man in charge.”

Bill Hare, the chief executive of Climate Analytics, said: “This is an extraordinary, revealing, worrying and belligerent exchange. ‘Sending us back to caves’ is the oldest of fossil fuel industry tropes: it’s verging on climate denial.”

“Al Jaber is asking for a 1.5C roadmap – anyone who cares can find that in the International Energy Agency’s latest net zero emissions scenario, which says there cannot be any new fossil fuel development. The science is absolutely clear [and] that absolutely means a phase-out by mid-century, which will enhance the lives of all of humanity.”

"At the U.N.'s #COP28 #climate summit, 118 governments pledged to triple the world's #RenewableEnergy capacity by 2030, ... led by the European Union, United States and UAE.

While China and India have signalled support for tripling renewable energy by 2030, neither backed the overall pledge on Saturday - which pairs the ramp-up in clean power with a reduction in #FossilFuel use."

Leaders at COP28 are pushing starkly different hopes for fossil fuels. King Charles III of Britain pleads for climate progress, seemingly at odds with the British Government.
After COP28 president Sultan Ahmed al-Jaber proposed embracing the continued use of fossil fuels, the U.N. Secretary General said: "We cannot save a burning planet with a fire hose of fossil fuels."

On July 14, I wrote that we had broken even on power, we had consumed as much electricity as we had produced this year. The surplus we built up during the rest of the summer is now gone. We broke even again at 8.41 MWh.

At the end of the year, we'll have a deficit of ~1 MWh which I think is great since it's a 220m2 house with everything on electricity.

#RenewableEnergy #batteries

Giant batteries that ensure stable power supply by offsetting intermittent renewable supplies are becoming cheap enough to make developers abandon scores of projects for gas-fired generation world-wide.

The long-term economics of gas-fired plants, used in Europe and some parts of the United States primarily to compensate for the intermittent nature of wind and solar power, are changing quickly, according to Reuters' interviews with more than a dozen power plant developers, project finance bankers, analysts and consultants.

Interestingly, when looking at which #renewableenergy source to prioritise governments might be well advised to (for the moment at least) to pivot towards #solar.

It looks like both the ease of manufacture of components & the current post-Covid glut in the #supplychain are driving down the prices of solar components, while the more complex mechanical needs of #windpower are keeping prices high(er).

So a pragmatic policy right now would be to focus on ramping up solar energy...

I think there's a message in it for Australia. Like Portugal, we're nuclear-free. Hydro will be a challenge, we don't exactly have a lot of dams suitable for that, but we should be putting solar on every roof we can, setting up wind farms and improving our battery storage.

"Brazil won't be able to triple its own renewable energy because it's already very high," a Foreign Ministry spokesperson said."

Of course, the EVs that are inevitably coming to Brazil will increase the electricity demand.

I appreciated this Foreign Policy article that talks about how the green transition will mean LESS mining, not more.

Though I wouldn't call the argument that renewables require an unacceptable amount of mining an "emerging narrative" – seems like people have been making that claim for years now.

Flooded mines across the UK could store large amounts of wind energy that would otherwise go to waste by heating up the water within them. The heat could then be extracted to warm homes in winter.

A test of the idea is being planned in Scotland in 2024.

Here's a Guardian article saying that China's CO2 emissions could peak this year thanks to a record surge in green energy investments.

The article says Beijing’s 2023 solar and wind installation targets were met by September, and electric vehicle penetration is well ahead of the country's 20% target for 2025.

What will the "what abouters" do when they can no longer use China as an excuse not to move away from fossil fuels? 🤔

The Queensland state grid has reached a new peak in solar output – in terms of share of local demand – with a new benchmark of 71.2 per cent set at 11.35am on Thursday.

The new record for the share of solar beat the previous peak of 69.9 per cent set in September this year and combined rooftop solar (about 3.6 GW at the time) and utility scale solar (2.5 GW), according to data experts GPE NEMLog2.

It suffers from the same fundamental problem as vertical axis wind turbines. At some point, the blades are travelling into the wind. That's not good for efficiency.

The saving grace might be construction & maintenance costs.

It looks too simple.

$0.013/kWh wind energy from simple mass manufacturable parts that can be transported easily and constructed with well known techniques.

It seems like it would require a lot of land. But my estimate is that it's about the same as we currently use for coal power in Victoria (mines, powerplants and cooling ponds)

“Energy Vault claims its technology, based around ‘storage towers’ of custom-designed bricks, replicates the gravity-based approach of large-scale pumped-hydro storage, but at lower cost and without the need for water or particular topographies. Instead of water, the huge bricks are hauled upwards by crane to store energy and released for discharge, controlled by custom-designed software.”

Wind tubines:

1. Kill whales.

Bullshit. Constantly referring to results published nowhere from a study that never took place remains bullshit.

2. Reduce ocean swells, killing surfing.

Bullshit. You would have to build a literal wall of turbine towers to stop ocean swell, which developes over hundreds of kilometres. The best surf involves ocean swell and offshore winds, which simply can't be affected by offshore wind turbines.

3. Reduce onshore winds by 40%.

Bullshit. There is no indication that wind turbines reduce onshore winds. The wind continues past the turbine blades, they don't block it; they don't even slow it down by any reasonable measure. A couple of hundred metres past the turbine you can't measure any effect at all.

4. Reduce fishing catches.

Bullshit. The tower bases, buried in the ocean bed, provide safe places for fish nurseries and coral growth, increasing the local fish population.

Don't buy into the disinformation being spread in order to stop offshore wind turbine installations. Look at who benefits from them not going ahead.

Projects hijacked by ‘political actors like Peter Dutton suddenly pretending to care about whales’.

Associate professor Michelle Voyer was startled to see an article from the internationally esteemed academic journal Marine Policy asserting that wind energy projects proposed for the waters off the Illawarra and Hunter Valley would kill 400 whales a year pop up on social media.

After all Voyer lives in the Illawarra, and due to her role as principal fellow with the Australian National Centre for Ocean Resources and Security at the University of Wollongong, she has expertise in the field. She is also, it turns out, associate editor of Marine Policy. She did not recognise the article.
