Quite frankly I don't care either way, I just wanted a source. I'm happy you feel that way though. This is the best write up I found for lighting source, efficiency, and consumption relationship. As a first step in looking at this, I’ve taken the data from the analysis and plotted it on a log scale. This shows clearly how consumption has increased as population and incomes (measured by per capita GDP) have risen and prices have fallen. The central role played by efficiency is indicated by the dashed line, which shows the number of kWh needed to produce a unit of light (1/efficiency). Comparing this with the solid blue price line showing price indicates that the 100 fold fall in price per unit of light in the 20th century was due to increased efficiency, mainly as electricity replaced gas. Yet demand rose strongly over the period, increasing more than 100 fold. This challenges the view that increases in efficiency translate into reductions in demand, and thus emissions. https://onclimatechangepolicydotorg.wordpress.com/low-carbon-technologies-section-overview/long-term-trends-in-lighting-efficiency-and-consumption/ https://onclimatechangepolicydotorg.wordpress.com/low-carbon...
