about a decade ago renewables reached grid parity with conventional sources in most of the world and experience exponential growth so far. I hope the same happen for plant based products.
and you don't seem to understand...
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.
since death star is capable of delivery a blast with high energy density, its core might be a nuclear fusion or anti matter power plant. maybe the mass there generates sufficient gravitational force.
my understanding is that Taiwan buys weapons from the us, so he is demanding something that is already a common practice
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.
because simplified Chinese characters borrowed many words directly from Japanese kanji, so google translate still recognizes it.
Meanwhile the world still building wind solar battery faster than ever...
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)
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.
