Economic Effects of Renewable Energy Expansion Policy: Computable General Equilibrium Analysis for Korea

Abstract

<jats:p>This study examines the effects of renewable energy expansion policy on the Korean economy and industries using the computable general equilibrium model, which divides the power generation sector into detailed generation technologies and sources. The scenarios are set to observe the cases where the share of solar photovoltaic and wind power generation reaches 7%. The effects are examined according to differing circumstances, such as when greenhouse gas (GHG) emissions are regulated, and the funding source for renewable expansion varies. The results show that renewable expansion policies have negative effects on GDP. However, the magnitude of the GDP decline becomes smaller when GHG emissions are regulated. The expansion of renewable energy induces the growth of upstream industries which supply components for renewable generation modules. Regarding employment, the renewable expansion policy can increase the demand for labor. However, the direction and the extent of the effect vary depending on the funding source. When overlapping regulations, such as the emission trading scheme and renewable energy expansion policies, exist in the power generation sector, the renewable energy expansion policy could provide incentives for GHG emission-intensive power sources.</jats:p>

Macroeconomic, Institutional, and Energy Consumption on Economic Growth APEC Members

“…In the short run, these investments have the potential to boost economic activity, generate employment opportunities, and contribute to GDP growth. (Oh et al, 2020) The IQ variable has no short-term influence on the GDP of APEC member countries. Short-term effects on GDP might not be immediately apparent as institutional improvements often need time before achieving measurable economic outcomes.…”

Renewable Energy (Solar and Wind) Generation and its Effect on some Variables for Selected EU Countries with Panel VAR Model

“…They find that there is an increase of employment due to the expansion of solar PV and wind power generation. Oh et al (2020) finds a positive relation among RE policies, RE generation and GHG emission reduction (i.e., environment). The large share of RE will support to emit less amount of GHG in the environment.…”

The Impact of Eco-Innovation and Clean Energy on Sustainable Development: Evidence from USA

“…Similarly, Soava, Mehedintu, Sterpu, & Raduteanu, (2018) found that RE contributes to economic growth in 28 European nations. Mikelsone et al (2020) and Ntanos et al, (2018) Oh, Yoo, & Kim, (2020) examined REW energy policy and its relationship with economic growth in Korean context. It is revealed that REW policies reduce economic growth, but this negative effect is reduced when greenhouse gases are regulated.…”
