Plus the 1% of lighting which comes from Kerosene lamps add's a further 20% to this.
- aetherson 13y agoI don't know where you're getting that claim from your link. It suggests that in the US, residential lighting is .14 * .38 = 5.32% of electrical supply, commercial lighting is .07 * .36 = 2.52% of electrical supply, and industrial lighting is .22 * .26 = 5.72%, for a total of about 13.5%. As far as I can tell, your link does not break down global electrical use. Your link further claims that electrical generation accounts for 34% of greenhouse gas emissions in the US, so .135 * .34 = 4.6% of all US greenhouse gas emissions in the US would be lighting-related. Transportation accounts for 27% of all greenhouse gas emissions, and your link doesn't break down what percentage of that is "cars." But unless only 1/7th of transportation CO2 emissions are from cars, lighting doesn't exceed it, in the US.
