This is strongly discouraged given the existing benefits of increased renewable energy investments in an African economy. Nigeria, the leading African economy is adopted as a representative to illustrate the prospects of improved (renewable) energy security in Africa. This study develops a dynamic recursive general equilibrium model to evaluate the prospects of renewable energy investment paths for Africa towards improving its energy security levels. Unlike other competing models, this model allows businesses to dynamically substitute between intermediate renewable energy and fossil fuel products, thus, taking active steps towards achieving a green economy. The results show that present economic welfare will be sacrificed for future welfare benefits and improved energy security. This confirms the transitioning of an economy from a lower steady state to a higher steady state path as postulated by the Solow model. However, a sustained gradual investment in the renewable energy sector yields the least welfare loss as the economy transitions through its energy security path. The one-off policy design produces relatively higher results in the immediate future while the sustained gradual incremental path smoothens these results into the far future. The results confirm that Africa's demand for renewable energies substantially outweighs its supply, thereby suggesting a potential and non-trivial market for renewable energies, nonetheless. Results-based policies that are geared towards improving energy security are formulated for the African economies.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"198 ","pages":"Article 114512"},"PeriodicalIF":9.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we conduct a transparent and quantified study of how subsidies affect the cost of low-carbon steelmaking as a case of industrial policy in a low-carbon transition. We first map subsidy intervention points across the steel supply chain in the US and the EU, showing how subsidies can cumulate over several segments. Afterwards, we use a bottom-up techno-economic model to quantify and compare subsidies with cost components including raw materials, energy, and labour costs in four hypothetical cases in Ohio, West Virginia, Germany, and Spain.

The main conclusions are as follows: (1) When the demand faced by an enterprise is uniformly distributed and the form of the carbon abatement cost function is a logarithmic function, the enterprise has three emission reduction strategies to choose from: output reduction, mixed emission reduction, and industry exit. (2) The carbon trading market can reach equilibrium when the participants take different emission reduction strategies.

As the auction ratio of carbon emissions rights increases, the enthusiasm of enterprises to participate in the carbon trading market decreases.

However, energy policies frequently conflate universal access with extending and subsidising networked electricity, resulting in technology-dominated approaches. Rapid urbanisation in the global south has outstripped infrastructure capacity, where urban dwellers' access to affordable, reliable, and sustainable forms of energy are precarious. This failure to reflect human needs and societal expectations alongside technical considerations is threatening the sustainability of urban energy transitions. This paper draws from qualitative data with low-income urban dwellers and municipal policymakers to critically examine South Africa's energy access policies. We demonstrate how prioritising ‘electricity for all’ via grid connections fails to deliver universal access to affordable energy. First, the state's emphasis on extending and subsidising networked electricity prioritises proximity to grid connections rather than access to energy services, and permanently excludes households living in un-serviceable structures/settlements. Second, limited community participation produces a policy that ignores low-income households' urban practices and creates perverse incentives to distort energy consumption. We argue that delivering an urban energy transition that is economically feasible, locally appropriate and socially desirable requires policy expansion <em>beyond</em> physical delivery, working with targeted communities on policy development, knowledge exchange, and capacity building.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":"198 ","pages":"Article 114506"},"PeriodicalIF":9.3,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is evidence of a non-linear relationship between FDI and inclusive growth, where FDI dampens inclusive growth to a certain point and begins to induce it after that point. Notably, the results reveal that FDI can effectively form synergies with both renewable and non-renewable energy consumption to promote inclusive growth in SSA. Also, our empirical results from the GMM is robust to Diskroll and Kraay methodology, which caters for cross-sectional dependence.

Using a novel panel fixed effects model, followed by dynamic panel data estimation techniques and structural equation modeling, a latent class modeling approach, the study controls for factors like Foreign Direct Investment (FDI), economic growth and urbanization. The empirical findings indicate that the effectiveness of environmental regulations in reducing carbon emissions is mediated by GCSI, which, in turn, is influenced by renewable energy transitions. This implies that regulatory measures have an indirect effect measurable through GCSI and renewables, and can be considered key performance indicators. Moreover, based on dynamic panel data estimations technique, the most of the statistically significant coefficients are found to be inelastic (<1), echoing a yet to achieve breakeven when it comes to tradeoff between environment and economic sustainability for overall EU-22 panel. Despite some high-income nations achieving significant environmental sustainability goals, uneven performance across the EU-22 highlights persistent challenges.

We model the aggregator’s maximization of V2G revenues over electricity, hardware, installation, and operating costs as a mixed-integer linear program.

Profitability is highly sensitive to the cost of V2G stations and the difference between the lowest charging and highest discharging prices.
