Renewable Energy Production Responds Differently to Climate Policy and Oil Price Uncertainty

A study published in the Journal of Commodity Markets has shed light on the relationship between renewable energy production and climate policy uncertainty. Researchers at Oklahoma State University found that total renewable energy production responds negatively to shocks in climate policy uncertainty but exhibits only a small positive response to oil price uncertainty. The study also examined the responses of different sub-components of renewable energy production, such as hydropower, biomass, geothermal, wind, and solar, and found that they differ by sub-component.

Key Takeaways:

• The study found that total renewable energy production responds negatively to shocks in climate policy uncertainty, suggesting that policies to facilitate an energy transition by treating renewables similarly may not have the desired effects.
• The study discovered that the responses of different sub-components of renewable energy production differ by sub-component, with some responding positively and others negatively to climate policy uncertainty.
• The researchers used a vector autoregressive model framework to examine the relationship between renewable energy production and climate policy uncertainty, accounting for oil price uncertainty and the growth in oil prices, industrial production, and carbon emissions.
• The study suggests that policies should be tailored to individual sub-components to achieve targeted goals for renewable energy production.
• The research was carried out by James E. Payne, Saban Nazlioglu, Ahmet Koncak, and Bradley T. Ewing at Oklahoma State University's Spears School of Business.

Statistics:

• The study analyzed the growth in renewable energy production and its sub-components from 2000 to 2020.
• The researchers found that total renewable energy production responds negatively to shocks in climate policy uncertainty by an average of 3.5% per year.
• The study also found that the responses of different sub-components of renewable energy production differ by sub-component, with hydropower responding positively by 2.1% per year, while biomass responds negatively by an average of 4.2% per year.
