Promoting investment in energy efficiency has become increasingly important over the past decade, but not much is known about effective ways to promote firm-level investments in energy efficiency. Using new experimental data on EU firms’ stated willingness to invest in hypothetical energy-efficiency projects with varying offers of financing and technical assistance, this column demonstrates how a favourable financing offer can increase the likelihood that firms are willing to invest in energy efficiency by as much as 33%.

Electricity prices can vary dramatically within a single day. However, most analyses of energy efficiency programmes ignore this variation, focusing on total energy savings without regard to when those savings occur. This column uses hourly smart-meter data to demonstrates a surprisingly large variation in economic value across energy efficiency investments. Air conditioner investments, for example, deliver savings when the value of electricity is high, increasing their value by about 50%.

Urbanisation in India is taking many twists and turns. Organised manufacturing is moving out of urban areas, while unorganised manufacturing is transitioning towards urban areas. As the fourth greatest energy consumer in the world, how the country manages this ongoing industrialisation and urbanisation process will have important environmental implications. This column looks at the relationship between growth, geography, and energy efficiency in manufacturing in India. Electricity consumption per unit of output has declined in urban and rural areas, but these overall trends mask substantial variation between states and substantial potential for further efficiency improvements in energy-intensive industries.

Efficiency standards appear to be at the centre of US climate policy. But is this policy effective? This column argues that, thinking laterally, evidence suggests that there are reasons to be suspicious. If the US is to focus so heavily on energy efficiency, we ought to have a better understanding of its effectiveness.

Policies to improve management practices – such as competitive markets, business training and professional, rather than hereditary family, management – improve productivity and economic growth. Could this be at the cost of higher energy usage? This column, using extensive survey and experimental data, suggests that, quite to the contrary, well-managed firms are substantially more energy-efficient.

Trains use three times less energy than cars to transport people; six times less energy than trucks to move freight. Trains use and emit just one-fifth the amount of carbon dioxide. Governments can help fight global warming by using competition policy and tax incentives to induce transportation customers to switch to rail.
