Our known fossil fuel reserves are soaring. New finds of coal, natural gas, oil, tar sands, and oil shale keep growing, not declining.

已知的矿石燃料储备猛涨；不断有新的煤矿、天然气、石油、焦油砂和油页岩被发现；人口数量也在增长。

For instance, Craig Venter's Synthetic Genomics and other companies are trying to develop microbes that turn coal, tar shale and oil into methane.

例如，克雷格·文特尔(Craig Venter)的合成基因学说，以及其他一些公司正在试图开发把碳、页岩焦油和原油变为甲烷的微生物。

We mine coal in South Africa and produce natural gas and condensate in Mozambique, oil in Gabon and shale gas in Canada.

我们在南非开采煤炭、在莫桑比克生产天然气和凝析油、在加蓬生产石油以及在加拿大生产页岩气。

For their calculations, the two assumed that where there was a gap between demand and conventional supply it would be filled with synthetic fuels, first with tar-sands oil and later with oil from coal and shale. (According to high-end estimates, coal and oil shale could together yield some ten trillion barrels of unconventional crude.) They then calculated what the impact would be on global carbon-dioxide levels.

President Obama specifically mentioned clean coal, shale oil and gas as well as well bio-fuels and renewable energy.

Unconventional sources of oil and gas that are set for further exploitation include Canada's tar sands, shale and coal-bed methane deposits around the world.
