Understanding beliefs about climate change is important, but most of the measures used in the literature are unreliable. Instead, this column uses prices of financial products whose payouts are tied to future weather outcomes in the US. These market expectations correlate well with climate model outputs between 2002 and 2018 and observed weather data across eight US cities, and show significant warming trends. When money is at stake, agents are accurately anticipating warming trends in line with the scientific consensus of climate models.

Increased reliance on solar and wind power has changed the approach to managing peak demand. The column details the results of a Danish experiment designed to flatten demand in which customers were randomly assigned to receive rebates based on how much consumption they could shift between periods of the day. Asking customers to shift consumption to periods of low net demand would create daily cost savings of €100,000 for the utility in question. Paradoxically, demand-shifting reduces the need for installed generation capacity, but increases overall demand.

We're not short of policies intended to save us from catastrophic climate change, but should monetary policy be part of this effort? Dirk Schoenmaker of Erasmus University thinks so, and he tells Tim Phillips how it would work in practice.

Despite leading the world in clean energy investment in recent years, China continues to engage in massive expansion of coal power thanks to policies that effectively subsidise and (over)incentivise coal power investment. This column examines the effects of the 2014 devolution of authority from the central government to local governments on approvals for coal power projects. It finds that the approval rate for coal power projects is about three times higher when the approval authority is decentralised, and provinces with larger coal industries tend to approve more coal power.

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%.
