I looked into the gwp* thing and it is more appropriate for macroscopic / global analysis than for the carbon accounting of individuals. if one reduces 1 unit per year of emission of short live GHG now, can they claim the positive climate effects by comparing with the counterfactual baseline, where they continue to emit the GHG with the same rate forever? That is the equivalent of claiming an infinite amount of emission reduction.
in any case it is always possible to use a pulse response function to account for the gwp of any instantaneous emission increase/decrease, since gwp* is just the convolution of the pulse response over time.
just thinking: why stop at 2? I suppose a grid of heat towers with mirrors beneath would provide maximum utilization of the solar radiation
its the marginal cost of running existing plants, mainly from fuel cost.
The political context here is that the Australian conservatives (the liberal coalition I suppose), who have been vividly against climate policies and renewables, are now trying to propose nuke projects on coal power plant sites. Many of these coal power plants are soon to be phased out with renewables plus storage in the queue for the freed transmission capacity, so there isn't really any advantages these sites can offer for nuke projects decades from now.
Of course, any realistic realization of nukes in Australia would be no earlier than 2040 (some even suggest 2050), by then they could already get 100% renewable in energy system easily.
my understanding is that Taiwan buys weapons from the us, so he is demanding something that is already a common practice
just a reminder if they put the orange diamonds for wind and solar it would probably lie somewhere near zero $/MWh
It is highly dependent of the local geological conditions. Convection-based geothermal plants (those with hot spring flowing around) probably have less constraints on heat extraction limit. Conduction-based geothermal plants will face more problems.
In some shallow geothermal use case the ground is used as seasonal heat storage so heat renewable rate is not an issue.
The moemorphic character shown in the picture is Archchan, created by ravimo. I wonder why show her in a discussion about Mint?
It's not a good analogy. A better analogy might be a community that promotes a Linux distro that runs exclusively on Chromebook and claims that that is the ONLY private and secure way to use a computer.
Some people are still using current primary energy supply share of renewables to bash wind and solar. Given the rapid adoption of these techs, such unfair metric will become more and more irrelevant. Once thermal electricity generation becomes the exception, electricity becomes the main primary energy carrier. Some forms of secondary energy carriers will still exist (in form of green chemical molecules) but overall efficiency of the energy system will no doubt improve.
I felt the slap in the face. It is good that Momoka acknowledges Nina is not just a punk token for her nostalgie and will start fight with her for what they think is the right way of doing music.
Since android are not subject to the risk, I wonder what happens if one connects the computer with hot spot from android.
Edited: just found out in the original report hot spot was also mentioned as a mitigation technique.
I hear you can self host sth called photovoltaic on your rooftop to get it for free!
If you are serious with this relationship (or you expect to still have Chinese partners in the future), I strongly recommend you buy a separate device for all the Chinese spywares required to maintain communication with your partner(s). At some point you will have to enter China, and it is best that you take only this device with you into it then.
Due to work I need to use Microsoft outlook mail on a daily basis. What I would like to know is the privacy and security concerns of various options:
- Login and use outlook on a browser for general purposes
- Use a tailered third party client from flatpak such as https://flathub.org/en-GB/apps/io.github.mahmoudbahaa.outlook_for_linux
- Use thunderbird
- Any other possibilities
And the article doesn't even mention renewables once... I mean, the technologies that are actually bringing down electricity prices and emissions
To triple the RE capacity by 2030, we need to double the current speed, or linearly increase the deployment speed until it reach 1.5TW/yr by 2030.
Ambitious but totally feasible.

I remembered vividly when some people predicting soaring high coal electricity generation would occur in Germany for 2023 back in April. Of course, those who had been studying the actual Energiewende for a while knew that would never be the case.
Interestingly, most of Germany import in 2023 was also from renewables. One could say that German coal has been beatened by growing renewables both at home and abroad.
I have a LED lightbulb that starts to flicker. Is there anyway to fix it, or any parts of it that could be useful for other uses(i.e. diodes for use in electrical circuits)?
Correction: After checking the product serial number carefully it is a fluorescent lightbulb as many pointed out. Thanks for the correction and advice.
(PS I am renting a house now so the type of lightbulb is of my landlord's choice. Obviously were I to choose I would rather have a LED lightbulb)
In the very first days of Israel's most recent war against the Palestinian people, as I saw the news, I realized how many rooftop solar panels there were in Gaza. Not going to lie, it was a surprising and yet simultaneously encouraging scene to see, knowing that these solar infrastructures provide much needed electricity to the local population.
Unfortunately solar currently only supply 20% of electricity demand in Gaza. Palestinian thinktank cited cost and blockade as the main barriers for a more rapid deployment of solar.
>Beyond costliness, the Israeli regime has sporadically restricted the entry of materials needed to install solar energy equipment over the past two decades. Moreover, its successive attacks on Gaza have destroyed necessary infrastructure for PV system installation, including residential buildings needed to house a rapidly expanding population, expected to reach 3.1 million in 2030. Combined with diminishing land and roof space, these realities render it extremely challenging for most Palestinians in Gaza to consider adopting PV technology.
Nevertheless, solar deployment in Gaza is still a remarkable achievement. Around a fifth of Gazans have installed solar power in their homes, which is about the same residential solar uptake percentage in Nederland (the EU state with highest solar installed per capita).
Similar to the case in Ukraine, the deployment and actual resiliency of renewable energy infrastructures in Gaza provides invaluable lessons for other people around the world, especially those who are or could at any moment be involved in a similar military conflict.
Original comment paper: Unfounded concerns about photovoltaic module toxicity and waste are slowing decarbonization
I read the paper. Behind paywall unfortunately, but the Cleantechnica article quote the paper well enough.
TLDR:
- Material waste from solar very small compared with other activities. !
- Most common PVs contain almost none harmful materials. Trace amounts of lead in crystalline silicon modules and the cadmium in CdTe modules are the only potential harm IEA found. But Pb is being phased out, and CdTe compound is quite stable in CdTe modules. Both cadmium and tellurium are recycled into new modules.
- Module lifetime and reusability is increasing.
> Treating decommissioned PV modules as a commodity and opportunity for material recovery, and not as hazardous waste would be environmentally and economically beneficial.
