But fuels could turn out to be the most profitable use of the waste products, if renewable diesel can take off.

但是，一旦可再生柴油能够起步，燃料将成为废弃物利用方面最赚钱的用途。

Now researchers at the startup LS9, based in South San Francisco, CA, have described the genes and enzymes responsible for this production of alkanes, the major components of fuels such as diesel.

现在位于南旧金山新创公司LS9的研究者命名了负责产生烷类的基因和酶，这种烷类燃料的主要成分是柴油。

When these oils are heated, their viscosity is reduced, and they can be burned directly in a diesel engine, or the oils can be chemically processed to produce fuels such as biodiesel.

当这些植物经过加热后粘稠度降低，便可直接在柴油机内燃烧，或者将部分油类经过化学方法加工为生物柴油。

But the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene.

It keeps other fuels, such as diesel, artificially cheap by the simple expedient of stopping state oil companies from raising their prices.

ECONOMIST: The vexing question of subsidies

The academics advocate concentrating first on short-term fixes for greenhouse gases or other warming agents, such as black carbon - particles emitted from the incomplete burning of fossil fuels, principally in diesel engines and wood stoves.

If it is true that we may expect a decline in the availability of cheap crude oil, and hence diesel and petrol fuels, upon which essentially all world transportation, manufacture and the production and transportation of food, and thus global growth depend, the news on the CO2 emission front must be good.
