Climate and economic policy are closely correlated with energy consumption. This study investigates the bi-directional causality between renewable (REC) and non-renewable energy consumption (NEC) and policy uncertainties. The time-varying bootstrap rolling window causality test considers structural changes and parameter instability. The results show that the causality between REC and climate policy uncertainty (CPU) is both negative and positive, which mainly stems from the attitudes of authorities towards climate change. If the Administration is positive for climate change mitigation, the correlation between REC and CPU is positive; otherwise, it is negative. The nexus between NEC and CPU is mainly positive, except during global financial crisis periods. This reflects that climate policies are affected by financial crises due to financial constraints. For comparison, we further analyse the dynamic correlation between energy consumption and economic policy uncertainty (EPU). EPU has a significant negative impact on REC in most subperiods, while it has a positive impact on NEC. This can be explained by the fact that non-renewable energy is cheap and convenient to use during economic downturns. Moreover, crude oil has strategic reserve value, especially in the turmoil periods. Regarding policy implications, harmonious and coherent climate and economic policies are important for energy transition. [ABSTRACT FROM AUTHOR]

Woody biomass energy makes up a large share of renewable energy consumption in the EU, and the largest share in countries like Denmark. However, little is known about how the public perceive it. This paper presents the results of a questionnaire-based survey of the public in Denmark focusing on attitudes toward woody biomass for energy. The main findings are that, while more people favor than oppose it, a large proportion are undecided about the use of woody biomass. The survey also revealed a lack of knowledge about this energy source. A Best-Worst Scaling methodology revealed that Danes prioritize environmental sustainability concerns – namely biodiversity loss, the hindering of the development of other renewable energy sources and the climate change mitigation potential of woody biomass – over societal and/or economic ones when it comes to the promotion of woody biomass. Finally, it was found that concern about climate change, belief in the mitigation potential of woody biomass, and being younger explained the formation of positive attitudes toward woody biomass. Policy makers aiming to take public concerns into account in discussions about Denmark's energy future should focus more on minimizing the negative environmental impacts associated with woody biomass rather than on its economic benefits.

Whether an enormous untapped hydropower resource should be utilized domestically by heavily electrifying energy end-uses or should be exported to neighboring countries is often debated in Nepal. This study attempts to bring both policy options together and justifies with evidence the need to integrate end-use electrification and cross-border electricity trade policies in the energy transformation of Nepal. We found out that Nepal will continue to import electricity till 2027 to meet its electricity demand throughout the year though it has already started exporting its surplus electricity during the wet season because of the full availability of run-of-river type hydropower. The run-of-river will continue to dominate Nepal's least-cost generation mix with a two-thirds share resulting in considerable surplus electricity during the high-flow season. Such surplus will exceed one-third of its total energy generation capacity in long-run in all end-use electrification scenarios (low to high). Nepal can use its existing cross-border electricity trade mechanism to sell its surplus electricity and can generate revenue of 67 billion USD in the high electrification scenario, which, combined with savings from fossil fuel import savings, can provide 85 % of total electricity generation investment needs.
