Abstract A substantial amount of primary and secondary energy is consumed by the residential sector. Residential energy consumption includes energy required for construction activity and household consumption. Hence there is a need to quantify energy consumption, its significance and causes. Calculating energy intensity of goods and services is the first step towards quantifying the causes. This research is based on the 115 sector classification input–output tables for India, for 1993–94, 1998–99 and 130 sector classification input–output tables for 2003–04 and 2006–07. Energy intensity of sectors related to household consumption has been calculated to analyze the trend between 1993–94 and 2006–07. Indirect energy requirements of Indian households have been assessed in this study from calculations of total primary energy intensity along with private final consumption expenditure. Results indicate that energy consumption has increased for all categories except “medical care and hygiene”. Percentage increase in indirect primary energy consumed by households is maximum for “house building” and “recreation” categories. Finally a complete decomposition analysis of indirect primary energy consumed by households has been carried out based on changing structural composition of the private final consumption expenditure, energy intensity patterns, per capita expenditures on energy and population.

Abstract Although the environmental benefit from implementing a climate tax is usually realized, the economic dividend still remains a controversial issue warranting further research. This is because the impact of an environmental policy on an economy-wide system will depend on factors that differ from one region to the next. In this paper, we develop a static CGE model for Liberia that is capable of analyzing both a uniform and a partial carbon tax policy. Under the uniform policy instituted to ensure mitigation in the range of 20–50%, an economic dividend is found for energy, employment, and welfare. In particular, energy consumption increases by between 5 and 15.5%, respectively. Interestingly, under a second best policy which exempts economically strategic sectors from the tax, no economic dividend is found for all three variables. This time, energy use declines by between 2 and 9%. These suggest that a uniform environmental tax policy is a more viable option for Liberia, in particular, as it does not only generate economic dividend for employment and welfare, it also incentivizes Liberia's adoption and use of renewable energy technologies. In general, based on the results obtained, further conditions for the feasibility of a double dividend are proposed.

Abstract It is pointed out that the apparent decision of the United States to end development of the Yucca Flat, Nevada repository for permanent disposal of radioactive waste may inadvertently place it at variance with the disposal principles of the International Atomic Energy Agency (IAEA) which caution nuclear nations that “ The burden on future generations shall be minimized by safely disposing of high level radioactive wastes at an appropriate time, technical, social and economic factors being taken into account. ” It is then shown that the IAEA's ten technical criteria for underground disposal can seemingly be met by storing vitrified waste a kilometer underground in the crystalline basement rock of a mid-continent shield, where: (a) it should be invulnerable to redistribution by incompetence, natural disaster, or terrorism and (b) there is no obvious pathway for leakage into the biosphere. Finally, a method is proposed by which the storage impasse may be broken.

Abstract Transformation of Asia's transport sector has vital implications for climate change, sustainable development and energy indicators. Papers in this special issue show how transport transitions in Asia may play out in different socio-economic and policy scenarios, including a low carbon scenario equivalent to 2 °C stabilization. Accounting for heterogeneity of national transport systems, these papers use diverse methods, frameworks and models to assess the response of the transport system to environmental policy, such as a carbon tax, as well as to a cluster of policies aimed at diverse development indicators. The analysis shows that CO2 mitigation in a transport system is achieved more effectively by aligning mitigation policies with sustainable development policies and measures such as mandates for mode share and choices such as urban design, information and communication systems, and behavioral measures. Authors therefore advocate policies that target multiple dividends vis-a-vis carbon mitigation, energy security and local air quality. Whereas four papers focus on emissions mitigation policies, one paper examines challenges to adapt fast growing transport infrastructures to future climate change induced risks. Collectively, the papers exemplify a set of policies and measures that can deliver co-benefits, and, also, demonstrate the use of methods, frameworks and models to delineate the optimal mix of such policies and measures.

This paper investigates how risks are anticipated in national bioenergy policies and in which way related expectations that harms can be prevented or mitigated have actually been met. The paper draws on the national biofuel policies of ten countries and the EU, selected to represent a diverse sample of regions, producers and consumers, and pioneers and latecomers. It proceeds in two steps: firstly, it identifies three risk categories most frequently mentioned across the investigated national policies. Secondly, it conducts a systematic review of available empirical research about biofuels’ effects in these risk categories. Findings are discussed regarding the empirical conditions under which related expectations to do no harm have materialized or failed; and concerning the challenges of risks perception and management in actual policies. We observe issues of crop selection and inadequate sectoral governance of biofuels, but also challenges of large-scale modes of intensive production. Effective risk mitigation was often the result of risk adverse choices by contract farmers engaged in biofuels production. National policy documents have insufficiently conceptualized ‘do no harm’ concepts and strategies in place to address these performance issues; while remaining silent on the particular risk governance and accountability framework that keeps track of actual developments, commitments and responsibilities.

Abstract Previous experience has demonstrated the tenuous nature of biomass energy projects located at livestock facilities in the U.S. In response, the economic sustainability of a 710 kW combined heat and power biomass energy system located on a dairy farm in California was evaluated. This biomass energy facility is unique in that a complete-mix anaerobic digester was used for treatment of manure collected in a flush-water system, co-digestates were used as additional digester feedstocks (whey, waste feed, and plant biomass), and the power plant is operating under strict regulatory requirements for stack gas emissions. Electricity was produced and sold wholesale, and cost savings resulted from the use of waste heat to offset propane demand. The impact of various operational factors was considered in the economic analysis, indicating that the system is economically viable as constructed but could benefit from introduction of additional substrates to increase methane and electricity production, additional utilization of waste heat, sale of digested solids, and possibly pursuing greenhouse gas credits. Use of technology for nitrogen oxide (NO x ) removal had a minimal effect on economic sustainability.

Research on the nexus between energy consumption and economic growth is a fundamental topic for energy policy making and low-carbon economic development. Russia proves the third largest energy consumption country in the world in recent years, while little research has shed light upon its energy consumption issue till now, especially its energy–growth nexus. Therefore, this paper empirically investigates the dynamic nexus of the two variables in Russia based on the state space model. The results indicate that, first of all, Russia's energy consumption is cointegrated with its economic growth in a time-varying way though they do not have static or average cointegration relationship. Hence it is unsuitable to merely portrait the nexus in an average manner. Second, ever since the year of 2000, Russia's energy efficiency has achieved much more promotion compared with that in previous decades, mainly due to the industrial structure adjustment and technology progress. Third, among BRIC countries, the consistency of Russia's energy consumption and economic growth appears the worst, which suggests the complexity of energy–growth nexus in Russia. Finally, there exists bi-directional causality between Russia's energy consumption and economic growth, though their quantitative proportional relation does not have solid foundation according to the cointegration theory.

Abstract A study of the relationship between electricity use and economic development in over one hundred countries, constituting over 99% of the global economy has been undertaken. Correlations between electricity consumption/capita and GDP/capita have been analysed and compared with those between total primary energy supply/capita and GDP/capita. A supporting analysis has correlated the proportion of energy used in the form electricity, the `e/E ratio', with GDP/capita. The general conclusions of this research are that wealthy countries have a stronger correlation between electricity use and wealth creation than do poor countries and that, for the global economy as a whole, there is a stronger correlation between electricity use and wealth creation than there is between total energy use and wealth. The study also shows that, in wealthy countries, the increase in wealth over time correlates with an increase in the e/E ratio. The results imply that the energy ratio ($/toe) should be replaced by the electricity ratio ($/kWh) as a development indicator and, more precisely, by the e/E ratio (kWh/toe).

Three sustainability aspects of bioethanol production in Brazil were considered in this paper. Results show that the recent expansion of sugarcane has mostly occurred at the expense of pasturelands and other temporary crops, and that the hypothesis of induced deforestation is not confirmed. Avoided greenhouse gas emissions due to the use of anhydrous ethanol blended with gasoline in Brazil (E25) were estimated as 78%, while this figure would be 70% in case of its use in Europe (E10). Conversely, considering the direct impacts of land use change, the avoided emissions (e.g., ethanol consumed in Europe) would vary from −2.2% (i.e., emissions slightly higher than gasoline) to 164.8% (a remarkable carbon capture effect) depending on the management practices employed previous to land use change and also along sugarcane cropping. In addition, it was shown that where the bulk of sugarcane production takes place, in state of Sao Paulo, positive socio-economic aspects are observed. The general conclusion is that a significant share of ethanol production in Brazil can be considered sustainable, in particular regarding the three aspects assessed. However, as production conditions are extremely heterogeneous, a generalization of results is not possible.
