Summary: This study examines the impact of renewable energy consumption on economic growth in Nigeria using a non-linear autoregressive distributed lag model. The findings suggest that in the long run, a positive shock to renewable energy consumption decreases economic growth, while a negative shock increases economic growth. This is different from existing literature, which mostly finds a positive relationship between renewable energy consumption and economic growth. However, in the short run, a positive shock increases economic growth, and a negative shock decreases economic growth, although the effects are not significant. The study recommends the use of cleaner technologies to maximize the benefits and minimize the adverse effects of renewable energy sources, especially wood biomass.

Summary: The purpose of this paper is to investigate the links between renewable energy, non-renewable energy, capital, labour and economic growth in Malaysia. The study finds that in the long and short run, positive shocks of non-renewable energy are greater than the positive shocks of renewable energy. Additionally, reducing renewable energy consumption accelerates economic growth, while reducing non-renewable energy consumption slows down economic growth. Measures need to be taken to develop renewable energy and reduce dependence on non-renewable energy consumption.

Summary: This study focuses on the relationship between economic growth and energy sources in Pakistan from 1980 to 2016. The findings suggest that renewable energy has a long-term asymmetric impact on economic growth, while the long-term symmetric and asymmetric effects of GDP in both energy models are confirmed. This highlights the importance of renewable energy in boosting economic growth and the potential negative impact of reducing its use on Pakistan's economy.

Summary: Non-renewable energy is crucial for economic growth but leads to significant carbon emissions. This study examines the relationship between energy consumption, economic growth, and CO2 emissions using data from three major emitters. The findings show that energy consumption impacts economic growth, with oil consumption having positive effects in the US and India, and negative effects in China. Coal consumption also affects each country differently. Furthermore, energy consumption patterns influence CO2 emissions, with increased oil consumption increasing emissions in all countries. The role of coal consumption in emissions is more complex, varying across countries.

Summary: This paper investigates the effects of ICT on economic growth and energy consumption for 27 countries with high ICT development index rankings from 1990 to 2019. The panel NARDL model approach confirms a long-run asymmetric effect of ICT on economic growth and energy consumption. Negative changes in ICT adoption and usage can have severe consequences on economic growth, while positive or negative shocks to ICT increase energy consumption, indicating the rebound effect. The findings also reveal that economic growth in these countries is energy dependent in the short-run but energy independent in the long-run. Several important policy implications are drawn.

Summary: This paper examines the asymmetric effects of oil price shocks on coal and renewable energy consumption in China. The results show that oil price increases have significant short-term effects on coal energy consumption, but have a positive long-term impact on renewable energy consumption. Additionally, the relationship between coal energy consumption and economic growth follows a U-shaped pattern.

Summary: Using a non-linear autoregressive distributed lag time-series analysis, this paper examines the causal relationship between climate change, the tourism sector, and energy consumption in Turkey. The balancing act between a country's economic growth and the environmental degradation caused by tourism and energy is vital for addressing the issue and creating effective economic policies. The findings suggest that a decrease in tourist arrivals and an increase in renewable energy consumption may contribute to lowering temperatures, while an increase in non-renewable energy consumption may lead to temperature rise. Mitigating climate change and promoting sustainable economic growth through efficient tourism policies are crucial.

Summary: The study shows that with the increase of renewable energy proportion, there is an inverted U-shaped curve in economic growth, indicating that renewable energy can initially contribute to economic growth. However, once the proportion of renewable energy consumption reaches a certain point, economic growth will decline. Most countries have not yet reached this threshold and can promote renewable energy development through technological innovation and distributed energy systems.

Summary: This study empirically examined the long-term impact of energy intensity, renewable energy consumption, and economic growth on CO2 emissions across regions and income levels over 50 African countries from 1980 to 2018. The findings revealed that renewable energy consumption contributed to mitigating CO2 emissions, while energy intensity promoted emissions across regions and income levels, and at the African level. Economic growth affected CO2 emissions negatively at the African level but the effect was mixed across regions and income levels. The study also found bi-directional causations between CO2 emissions and its determinants in African, and some regions and income levels, with unidirectional causation highly supported across regions and income levels. Impulse response and variance decomposition analysis showed that both energy intensity and economic growth counted higher variations of CO2 emissions, while renewable energy highly contributed to reducing emissions within 10 years.

Summary: This study examines the impact of total and renewable energy consumption on economic growth at global and regional levels, revealing significant differences across income groups. While total and renewable energy have positive effects on global economic growth, the impact at the regional level is often negative or neutral, especially for renewable energy. Policymakers need to consider these findings in order to attract investment in renewable energy projects and ensure its positive impact on economic growth in all regions.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.

Summary: This paper provides insights into the optimal configuration of CSP plants with different penetrations of wind power by proposing an unconstrained optimization model. The results suggest that large solar multiples and TES are preferred in order to maximize profit, especially when combined with high penetrations of wind and photovoltaic plants. Additionally, the study demonstrates the economy and feasibility of installing electric heaters (EH) in CSP plants, which show a linear correlation with the penetration of variable energy resources.

Summary: This study investigates the optimization of power density in wind farms and its sensitivity to the available area size. A novel genetic algorithm (PDGA) is introduced to optimize power density and turbine layout. The results show that the PDGA-driven solutions significantly reduce the levelized cost of energy (LCOE) compared to the default layout, and exhibit a convex relationship between area and LCOE or power density.
