Environmental Effect: manufacturing carbon footprint

Latest comment: 2 years ago3 comments3 people in discussion

The values for manufacturing carbon footprint taken from https://ieeexplore.ieee.org/document/9518632 are off by a factor of 1000. The source probably conflated "kg CO 2 /kWp" with "g CO 2 /kWp". I found more sensible figures in the supporting info of https://doi.org/10.1038/ncomms13728 on page 3. However that article is already eight years old and cites even older values from eleven years ago.

I suggest to remove

"A 2021 study estimated the carbon footprint of manufacturing monocrystalline panels at 515 g CO₂/kWp in the US and 740 g CO₂/kWp in China,^[1] "

and instead write

"In 2013 the life cycle greenhouse gas emissions of multi-crystalline silicon PV systems was estimated as between 0.36 and 0.7 kg CO₂-eq/W_p^[2] "

Although maybe I forgot something, but I am sure 700 g CO₂ per kW_p would be ridiculously low. 194.76.232.147 (talk) 10:22, 29 January 2024 (UTC)Reply

This is a more up to date article: ^[3] reporting: "glass-backsheet (glass-glass) modules produced in China, Germany or the EU are linked to emissions of 810 (750), 580 (520) and 480 (420) kg CO2-eq/kWp, respectively" --Ita140188 (talk) 17:25, 30 January 2024 (UTC)Reply

I tried to correct the article - please could you guys check I got it right Chidgk1 (talk) 18:02, 26 June 2024 (UTC)Reply

Is there still a land constraint in South Korea?

Latest comment: 1 month ago1 comment1 person in discussion

I can't read Korea's just published renewables plan myself but land is not mentioned in https://www.asiae.co.kr/en/article/2026052009050147945 which says the grid is the biggest constraint. So is land a problem for solar expansion and if so is it specific to South Korea? Chidgk1 (talk) 19:00, 11 June 2026 (UTC)Reply

Is there still a land constraint in Japan?

Latest comment: 1 month ago2 comments2 people in discussion

https://japan-forward.com/japans-solar-boom-why-takaichi-is-pushing-back/ and https://www.nature.com/articles/s44406-026-00030-y say little about land but instead suggest epistemic injustice.

Anyway now they have the OHISAMA Project (see https://www.japantimes.co.jp/commentary/2026/05/31/japan/japan-winning-in-space-race/) perhaps the 2021 paper we cite re land is obsolete? Chidgk1 (talk) 19:19, 11 June 2026 (UTC)Reply

From my experience of working with Japanese solar development, land acquisition is one of the hardest and most expensive challenges of building solar in Japan. No time to look for source right now though, but there may be Ita140188 (talk) 12:59, 12 June 2026 (UTC)Reply
