So we should invest in Y. Y is diesel truck freight. We should invest in reducing the energy consumption of diesel truck freight.

The most cost-effective investment in reducing the energy consumption of diesel truck freight with at the same time the largest total reduction in diesel consumption is providing a Rapid Electric Freight Rail system that can capture a large share of existing long haul truck freight.

IOW, the argument, "X is more efficient, so we should invest in cutting use by Y", leads to the conclusion, "invest in electrification of rail and establishment of rapid freight rail, which cuts use by Y".


I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
