Energy Efficiency: Running to stand still?

Pickering Traction Engine Rally, P. StevensonIs energy efficiency a key factor in reducing greenhouse emissions?

Matthew Taylor of the RSA thinks home energy efficiency should take priority, and Amory Lovins of the Rocky Mountain Institute is also very keen on large scale efficiency gains.

The Jevons Paradox is the idea formulated in 1865 that making coal-burning more efficient will lead inexorably to the burning of yet more coal. Newcomen’s steam engine dramatically increased the use of coal in England and William Jevons’ (1835-1882) book The Coal Question noted this. but Jevons  also saw that James Watt’s more efficient version was what made coal-burning really take off, truly inaugurating the ‘age of steam’. He wrote: Continue reading
