Modern cargo ships slow to the speed of the sailing clippers | Environment | The Observer
A combination of the recession and growing awareness in the shipping industry about climate change emissions encouraged many ship owners to adopt "slow steaming" to save fuel two years ago. This lowered speeds from the standard 25 knots to 20 knots, but many major companies have now taken this a stage further by adopting "super-slow steaming" at speeds of 12 knots (about 14mph).

Travel times between the US and China, or between Australia and Europe, are now comparable to those of the great age of sail in the 19th century. American clippers reached 14 to 17 knots in the 1850s, with the fastest recording speeds of 22 knots or more.

Maersk, the world's largest shipping line, with more than 600 ships, has adapted its giant marine diesel engines to travel at super-slow speeds without suffering damage. This reduces fuel consumption and greenhouse gas emissions by 30%. It is believed that the company has saved more than £65m on fuel since it began its go-slow.

A green New Deal? | Green, easy and wrong | The Economist
This article commends financial penalties for pollution but not financial incentives for clean energy ("subsidies"). "Subsidising clean energy requires politicians to decide the best way of delivering clean energy, and their judgement is likely to be worse than the market's". Can a government subsidise clean energy across the board, without preempting the market by preferring one over another? I'd say so.

The high cost of using less water
ongoing costs in replacing infrastructure not covered by consumption taxes priced for high consumption but being applied in times of conservation/low consumption. This is happening in NZ for petrol (highway costs not being met by gasoline taxes).

Fuel for Thought: Financial Page: The New Yorker
Surowiecki hypothesizes why US consumers (who buy big inefficient cars) also overwhelmingly support higher fuel economy standards which would make such cars much harder to own. Analogy with NHL hockey helmet story.
