矿物燃料

Statistics analysis and some diagnostic ratios were used for source identification and the contribution rates of main sources were also calculated. Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion.

This is the kind of progress that led McKinseys to forecast that in as little as three years unsubsidized solar power could cost end-customers no more than electricity generated by fossil fuels in markets such as California and Italy.

这是一种进步，导致 McKinseys 预测说，在短短的三年里，无补贴的太阳能发电可能花费最终用户不多于市场上由矿物燃料所产生的电，如美国加州和意大利。

Solar energy and other renewable energy sources are a great alternative to fossil fuels. Other alternative energy sources, such as a water wheel or wind powered energy offer much less of a negative impact on the environment.

太阳能和其他可再生能源的来源是一个伟大的替代矿物燃料，其他替代能源的来源，例如作为一个水车轮或风动力能源提供少得多的负面影响，对环境的影响。

If this is the case, then it might seem like the burning of fossil fuels like petrol for our cars should have no affect on the atmosphere at all, and one could conclude that global warming is a myth thought up to scare us.

如果是这种情况，那麼它可能就像是燃烧矿物燃料汽油一样，为我们的车应该没有影响对大气层的一切，和一个可以得出结论，全球变暖是一个神话，以为最多吓唬我们。

They say part of the solution is to sharply cut use of fossil fuels.

他们说，解决问题的办法之一就是大规模减少矿物燃料的使用。

Society's dependence on fossil fuels is jeopardizing social and economic progress and our future security.

社会对矿物燃料的依赖正在破坏社会和经济进步，破坏我们的未来安全。

Our nation from fossil fuels should be understood as the most patriotic policy to which we can commit ourselves.

使我们国家放弃使用矿物燃料，应该被视为我们能够制订的最爱国的政策。

Weaning our nation from fossil fuels should be understood as the most patriotic policy to which we can commit ourselves.

使我们国家放弃使用矿物燃料，应该被视为我们能够制订的最爱国的政策。
