Kev nkag siab tseem ceeb:
Ib leeg60W incandescent teeb hloov los ntawm 9W LEDtxuag~ 500 kWh tshaj 10 xyoo.
Yog tias tag nrho cov teeb pom kev thoob ntiaj teb hloov mus rau LEDs,Kev txuag hluav taws xob txhua xyoo tuaj yeem tshaj 1,400 TWh(sib npaug rau500 thee- hluav taws xob hluav taws xob).
2.2 Kev txuag hluav taws xob thoob ntiaj teb los ntawm LEDs
IEA kwv yees (2023):LEDs tau txo cov teeb pom kev zoo thoob ntiaj teb kev xav tau los ntawm~ 40% txij li xyoo 2010.
US DoE Report:Los ntawm 2035, LED saws yuav txuag tau3,000 TWh cumulatively- sib npaug rau$250B hauv cov nqi hluav taws xob.
3. Kev txo cov pa roj carbon emissions: cuam tshuam ncaj qha thiab tsis ncaj
3.1 Direct CO₂ Savings
| Thaj tsam | Txhua xyoo LED Savings (TWh) | CO₂ Txo (Mt/xyoo) |
|---|---|---|
| European Union | 120 | 45 Mt(Denmark tag nrho emissions) |
| Tebchaws Meskas | 150 | 80 mt(20M tsheb tawm ntawm txoj kev) |
| Tuam Tshoj | 300 | 250 Mt(5% ntawm lub teb chaws emissions) |
| Is Nrias teb | 80 |
60 mt(10% ntawm lub zog sector emissions) |
Xam xam hauv paus:
1 TWh saved ≈ 0.5 Mt CO₂(nws txawv ntawm daim phiaj carbon siv).
LEDs hauv Asmeskas ib leeg tiv thaiv~ 80 lab tons ntawm CO₂ / xyoo- sib npaug rau kev kaw20 coal nroj tsuag.
3.2 Indirect Advantages
