Technological change is essential for balancing economic growth and
environmental sustainability. This study measures and documents energy-saving
technological change to understand its trends in advanced countries over recent
decades. We estimate aggregate production functions with factor-augmenting
technology using cross-country panel data and shift-share instruments, thereby
measuring and documenting energy-saving technological change. Our results show
how energy-saving technological change varies across countries over time and
the extent to which it contributes to economic growth in 12 OECD countries from
the years 1978 to 2005
