Summary Summary Satellite observed nighttime lighting in China more than doubled • from 1992 to 2009 from 1992 to 2009. The growth in lighting tracks growth in both GDP and population. • This pattern is typical of the countries undergoing rapid • development (e.g. Vietnam, Algeria, Albania, Portugal and others). d l ( i l i lb i l d h ) Developed countries, like USA have stable lighting across the same • time period, perhaps due to improvements in lighting efficiency? There is an indication that the growth of lighting in China slowed • due to the economic downturn that started in 2008. At some point it is anticipated that growth in lighting in China will At some point it is anticipated that growth in lighting in China will • stabilize, similar to the pattern of developed countries.
