In 2016, 1,100 million people lack access to electricity, mainly in developing countries in Africa, Asia and South America. In these countries, there is a large potential for hydroelectric production through off-grid microgrids, although not fully exploited. This work assesses the long-term sustainability of off-grid microhydro projects operating in rural indigenous communities. More specifically, four sustainability dimensions are analyzed: environmental, technical, socioeconomic and institutional, and specific indicators are proposed for each one. In particular, 6 micro-hydroelectric power plants in southern Venezuela are used as case studies. The data gathering includes surveys, technical visits and interviews with technicians, engineers and beneficiaries. Results show that the institutional dimension and, in particular, alignment between involved institutions has been fundamental for the long-term sustainability. Indeed, appropriate institutional alignment is the key to strengthening the impacts on: (i) the environmental dimension, minimizing emissions and impacts on local ecosystems; (ii) the technical dimension, improving adequacy and reliability of technologies; and (iii) the socioeconomic dimension, making efficient use of electricity to enhance education, health and productivity. Lessons learned and conclusions of this research can significantly contribute to improve future projects, in particular to the 22 included in the electrification plans of Venezuela in coming years.

In this paper we investigate the prospects for the large-scale use of low-emission energy technologies in Africa. Many African countries have recently experienced substantial economic growth and aim at fulfilling much of the energy needs associated with continuing along paths of economic expansion by exploiting their large domestic potentials of renewable forms of energy. Important benefits of the abundant renewable energy resources in Africa are that they allow for stimulating economic development, increasing energy access and alleviating poverty, while simultaneously avoiding emissions of greenhouse gases. In this study we analyse what the likely energy demand in Africa could be until 2050, and inspect multiple scenarios for the concomitant levels of greenhouse gas emissions and emission intensities. We use the TIAM-ECN model for our study, which enawbbles detailed energy systems research through a technology-rich cost-minimisation procedure. The results from our analysis fully support an Africa-led effort to substantially enhance the use of the continent's renewable energy potential. But they suggest that the current aim of achieving 300 GW of additional renewable electricity generation capacity by 2030 is perhaps unrealistic, even given high GDP and population growth: we find figures that are close to half this level. On the other hand, we find evidence for leap-frogging opportunities, by which renewable energy options rather than fossil fuels could constitute the cost-optimal solution to fulfil most of Africa's growing energy requirements. An important benefit of leap-frogging is that it avoids an ultimately expensive fossil fuels lock-in that would fix the carbon footprint of the continent until at least the middle of the century.

Limiting global warming to well below 2 °C requires the transformation of the global energy system at a scale unprecedented since the industrial revolution. To meet this 2 °C goal, 87% of integrate ...

Following the debate on the implications of international trade for global climate policy, this paper introduces the topic of the economic benefits from trade obtained by exporting countries in relation to the emissions generated in the production of exports. In 2008, 24% of global greenhouse gas (GHG) emissions and 20% of the employment around the world were linked to international trade. China “exported” 30% of emissions and hosted 37.5% of the jobs generated by trade worldwide. The European Union and the United States of America were the destination of 25% and 18.4% of the GHG emissions embodied in trade. The imports of these two regions contributed to the creation of 45% of the employment generated by international trade. This paper proposes the idea of including trade issues in international climate negotiations, taking into account not only the environmental burden generated by developed countries when displacing emissions to developing countries through their imports, but also the economic benefits of developing countries producing the goods exported to developed countries.

Solar energy is one option for reducing future greenhouse gas emissions. Offsetting 50% of all future growth in thermal electricity generation by photovoltaics (PVs) would reduce annual global carbon dioxide emission from projected increased levels by 10% in 20 years and 32% in 50 years. Several projects are under way worldwide to demonstrate the feasibility of PV systems. This paper examines the economic competitiveness of PV systems and concludes that even after including externality costs, without significant technological breakthroughs, the economics of PV applications are unlikely to allow for an unsubsidized, widespread adoption of this technology in the near future. Further, if the goal of PV transfer programmes is to limit future greenhouse gas emissions, there are larger and cheaper opportunities available in industrialized countries to achieve reductions. Alternative measures for ensuring a market for photovoltaics, hence providing manufacturers with opportunities to improve the current technology, include mandating that utilities install a certain quantity of solar technologies by a certain date. Finally, moving towards a renewable energy future that includes PV systems requires a sustained R&D programme that will lead to improvements in panel and other system efficiencies.

The concept of energy justice has emerged as an important theoretical and methodological tool aiding to understand challenges in the extraction, production and consumption of energy, and its societal, economic, environmental and security implications. We apply energy justice as an analytical framework to analyse the political, societal and environmental impacts of energy policies in the context of post-conflict instability. Using the Kosovo C project as a case study, a planned lignite power plant and its associated infrastructure, we utilise the three tenets of energy justice (distributional, procedural, and justice as recognition) and eight aspects of just energy decision-making to depict the opportunities and challenges of the empirical application of energy justice in a post-conflict environment. The application of energy justice to the Kosovo case identifies the legal/regulatory and the temporal dimensions as crucial challenges to just energy policies in a context in which: (i) the lack of due process, good governance, and ongoing post-conflict tensions aggravate the societal, economic and environmental impacts of energy policies; (ii) accessibility and affordability of energy is prioritised over the promotion of sustainability; and (iii) intra- and intergenerational equity concerns take a backseat in the face of immediate state-building priorities.

Abstract Energy systems in rural China are experiencing a transition from traditional fossil fuels to renewables. This paper aims to investigate the potential factors that influence the choices of rural residents regarding water heaters with a focus on the low-carbon transition to solar water heating systems. To this end, a face-to-face questionnaire survey is undertaken with 3404 rural households randomly selected among 12 representative provinces. A comprehensive set of discrete choice modelling approaches were used. The empirical results show that (1) sociodemographic variables have significant effects on residents’ first-stage choice of a water heater (to buy or not to buy) but few effects on the second-stage decision to choose electric, LPG, or solar water heaters (which type to buy); (2) information spillover is important to facilitate the usage of water heaters, particularly of solar products; (3) the electricity price, which is regulated at a very low rate, has no apparent effect on the choice of solar water heaters; (4) government subsidy has a significant effect in the first stage but no differentiated effect on the decision choice in the second stage. Policy and managerial implications are presented to speed up the ongoing low-carbon transition of energy systems in China.
