The implementation of renewable wind and solar energy sources instead of fossil fuels to produce such energy carriers as
electricity and hydrogen facilitates reductions in air pollution emissions. Unlike from traditional fossil fuel technologies,
air pollution emissions from renewable technologies are associated mainly with the construction of facilities. With present costs of wind and solar electricity, it is shown that, when electricity from renewable sources replaces electricity from natural gas, the cost of air pollution emission abatement is more than ten times less than the cost if hydrogen from renewable sources replaces hydrogen produced from natural gas. When renewable-based hydrogen is used instead of gasoline in a fuel cell vehicle, the cost of air pollution emissions reduction approaches the same value as for renewable-based electricity only
if the fuel cell vehicle efficiency exceeds significantly (i.e., by about two times) that of an internal combustion vehicle. The
results provide the basis for a useful approach to an optimal strategy for air pollution mitigation.

使用可更新的风能和太阳能取代非石油来制造象电和氢气这样的能源载体，可以减少空气污染物的排放。不同于传统石油技术，可更新能源技术所产生的空气污染物主要与能源设施的建设有关。.当前采用风能与太阳能发电的成本表明，当使用可更新资源取代天然气来发电时，减少空气污染物排放所用的成本比用可更新资源取代天然气制造氢的成本要少十多倍。
.在燃料电池车上使用基于可更新资源的氢取代汽油时，仅当燃料电池车的效率大大超过（比如2倍）内燃机，减少大气污染物排放的成本才和基于可更新能源的电能成本相近。
这些结果为找到一条通向减轻大气污染的最佳方法提供了基本依据。
