CNG: Taking gas where it has never gone before

摘要

Fashionable alternative energy sources (such as biofuels or wind) and climate rhetoric aside, the world which today draws 87% of energy from fossil fuels (oil, gas, and coal), will by the year 2030 still draw 87% from them - all this while the total energy demand will grow by 50%. People hate to hear unpleasant statistics, but there are many such statistics when it comes to alternative energy. Biofuels, for example, have a negative energy balance. They require more energy to produce than their consumption provides. And even ignoring this science, if all of the corn grown in the US were to be used to produce motor vehicle fuel, it would still be less than 20% of gasoline demand - and a lot of the world would go hungry.
