This paper, based on panel data of 16 cities of 2007, 2012 and 2017 in Shandong province, establishes a coordination model of population-economy-environment based on entropy and physical coupling model, which is used to study the temporal-spatial evolution of population-economy-environment system coupling coordination and to estimate their spatial Moran's indexes, and presents suggestions for Shandong's future development. Among 16 cities in Shandong province, their coupling coordination is improving thanks to a rising comprehensive development. The western inland is far behind the eastern and central in economy and population. A low spatial autocorrelation exists in their economy-population-environment development, but weakly positive between comprehensive development and coordination. Regional coordinated potential needs to be further developed.

This paper applies GREET model and WTW system to compare their energy consumption and pollution emission in a form of currency between the traditional petroleum and new energy vehicles (battery electrical, hybrid and fuel cell vehicles) during their entire life circles. On energy consumption, new energy vehicles save energy under similar energy structure and technical parameters. BEV is on the top in energy consumption with a decrease by 42% with the traditional petroleum vehicles. New energy vehicles chiefly contribute to carbon emission reduction, falling by 5.78% on hybrid, 32.86 on feul cell, and 21.54% on BEV compared to traditional, but with an increase by 35.36% on acid rain pollution emission. From the total costs, new energy vehicles are lower than the traditional except the BEV. Developing new energy vehicles, especially the BEV, is somewhat of more advantages than disadvantages, which may be improved as China's energy structure alters.
