Sustainable energy policy indicators: Review and recommendations

Nowadays, the development of a sustainable indicators’ framework towards the sustainable energy policy making should be characterized by clarity and transparency. Even though the energy policy making has been the subject of many researchers, studies proposing an appropriate framework of sustainable indicators that have to be used are not present in the international literature. The purpose of the current paper is to present an integrated review of the methodologies and the related activities of the energy indicators and to recommend an operational framework of appropriate indicators supporting thus the policy makers/analysts/citizens towards a sustainable energy policy making.     

Australian renewable energy policy: Barriers and challenges

Effective policy and regulatory frameworks are paramount to incentivising the deployment of renewable energy to achieve long term reductions in carbon emissions. Australia's renewable energy policy has taken significant steps towards encouraging the deployment of lower-emission energy generation. Significant policy barriers still exist at the federal and state levels, however, which have reduced the effectiveness of a concerted national effort to deploy renewables. The current policy landscape has favoured mature technologies which present the lowest investment risk at the expense of emerging options which may present greater efficiency and emissions reduction gains. The lack of support for emerging technologies delays their effective deployment and the accumulation of highly skilled human capital, until the medium to long term. This paper outlines the key policy frameworks, incentives and regulatory environment which encompasses the renewable energy sector, and presents a critical analysis of the barriers faced by the industry.     

Common factors and major characteristics of household energy consumption in comparatively well-off rural China

Common factors that influence Chinese rural household energy consumption are proposed and major demand characteristics of well-off rural areas are analyzed on the basis of survey data. A system of major characteristic indicators for rural household energy consumption includes effective heat consumption for livelihood per capita per day (EHC), the proportion of commercial energy in EHC (PCE) and annual electricity consumption for livelihood per capita (AEC). Typical values in three economic regions (out-of-poverty, well-off and rich areas) of China are also given.     

The unexpected challenges of using energy intensity as a policy objective: Examining the debate over the APEC energy intensity goal

AimsEnergy intensity (energy demand per unit of economic output) is one of the most widely used indicators of energy efficiency in energy policy discussions. Yet its application in real-world policymaking can be surprisingly problematical. This paper aims to provide guidance to governments and organizations considering using energy intensity as a policy objective.ScopeIn 2007 the APEC community adopted, then in 2011 revised, an APEC region-wide energy intensity improvement goal. This paper presents a case study of that experience, focusing on three key ‘lessons learned’. These lessons are not original findings. However, none of them have received the recognition they deserve, and consequently, they came as a surprise to many of those involved in APEC's policy discussions.ConclusionsThe three lessons are as follows: (1) Energy intensity improvement is happening surprisingly quickly, but not quickly enough to meet the world's energy challenges. (2) It is difficult to find a definition of energy intensity that can make it suitable for use as an indicator of regional energy efficiency. (3) Whether the GDP's of individual economies are converted to common currency using market exchange rates or purchasing power parity (PPP) can dramatically change regional energy intensity improvement calculations.     

Rural energy in China: Pattern and policy

An overview of energy consumption pattern by available data and the analysis of some relevant aspects of energy policy in rural China are presented in this paper. The most obvious trend is the steady decreased proportion of biomass use, from 70.79% to 30.95%, and increased percentage of coal and electricity use, whereas coal and biomass are the major energy sources in rural areas, accounting for more than 70% of the total rural energy consumption even in 2007. Moreover, the energy consumption varies tremendously across provinces both in total and by fuel types, due to diversities of geographic features, economic development levels and local energy source availability. The rural energy policy and strategy of China have been somewhat unique, characterized by multi-resources, multi-assortments and multi-distribution channels. Some evident transition features can be found for both the rural energy consumption structure and the rural energy policy during the concerned period, that is, from noncommercial energy to commercial energy and from just satisfying energy demand to multi-purposes considering more factors as rural development and environmental protection.     

Generating renewable energy from oil palm biomass in Malaysia: The Feed-in Tariff policy framework

The renewable energy (RE) industry in Malaysia began in 2001 in the context of the growing concern about future depletion of conventional fuels and the global environmental concerns about greenhouse gas emissions. The Small Renewable Energy Programme (SREP) is a tool that was first designed to drive the development of the industry based on the abundance of oil palm biomass reserves and other identified renewable energy resources. Due to the slow uptake of this scheme, a new system, the Feed-in Tariff (FiT) was introduced in 2011 to stimulate the industry. By considering the deficiencies of the previous scheme, this paper examines the sustainability of the FiT policy framework in steering the future expansion of small-scale biomass renewable energy businesses in Malaysia. Resulting from the evaluation of the current policy settings and a market based appraisal, this work outlines strategies for enhancing the scheme and suggests future studies aimed at improving the flaws in the present system.     

The role of large scale storage in a GB low carbon energy future: Issues and policy challenges

Large scale storage offers the prospect of capturing and using excess electricity within a low carbon energy system, which otherwise might have to be wasted. Incorporating the role of storage into current scenario tools is challenging, because it requires high temporal resolution to reflect the effects of intermittent sources on system balancing. This study draws on results from a model with such resolution. It concludes that large scale storage could become economically viable for scenarios with high penetration of renewables. As the proportion of intermittent sources increases, the optimal type of storage shifts towards solutions with low energy related costs, even at the expense of efficiency. However, a range of uncertainties have been identified, concerning storage technology development, the regulatory environment, alternatives to storage and the stochastic uncertainty of year-on-year revenues. All of these negatively affect the cost of finance and the chances of successful market uptake. We argue, therefore, that, if the possible wider system and social benefits from the presence of storage are to be achieved, stronger and more strategic policy support may be necessary. More work on the social and system benefits of storage is needed to gauge the appropriate extent of support measures.     

The future of biomass energy: A Fermi-calculation perspective

It is argued: (i) that the harvesting of terrestrial solar radiation to perform useful work is at least an order of magnitude more efficient when carried out by solar-thermal or solar-photovoltaic processes than when carried out by way of biomass conversion and (ii) that, therefore, biomass energy is unlikely to compete successfully with inanimately harvested solar energy—except of course in restricted niche applications.     

Regulating district heating in Romania: Legislative challenges and energy efficiency barriers

Many states in Eastern and Central Europe (ECE) possess extensive district heating (DH) networks that were constructed during the days of communist rule in order to provide a universally accessible energy service that supported Soviet development policies. But the post-communist transition was marked by the exacerbation of the sector’s numerous technical, economic, regulatory and environmental problems, accompanied by its abandonment in favour of alternative methods of domestic heating. Recent efforts to increase the use of DH in ECE as a result of environmental and energy security concerns have taken place in an absence of critical, context-sensitive research.     

Sustainable biogas energy in Poland: Prospects and challenges

The article investigates prospects and challenges for expanding of sustainable biogas energy in Poland. The number of Polish biogas fuelled power plants and installed electrical power during the 2001-2010 decade is presented. Current economical incentives for biogas energy are discussed. It is emphasized that some revisions to the Polish tradable certificate system are urgently needed in order to encourage energy crop cultivation and the use of best available power technologies. Further, promising, but mostly unexplored feedstocks, such as energy crops, grasses and sorted municipal organic wastes are analyzed. It is also revealed that agrobiogas is characterized by a unique feature of ‘negative net’ CO₂ atmospheric emissions and thus the role of agrobiogas in solving Polish CCS dilemmas is discussed. In regard to biogas energy systems it is stressed, that the cost of electricity from biogas is almost independent on the size of agrobiogas CHP power plants in the range of 0.2-5 MW_e. Therefore agrobiogas energy is well suited for distributed energy systems involving small-scale agrobiogas power plants offering more green jobs and improved local waste management characteristics. Finally, reliable technologies suitable for biogas energy conversion and upgrading of biogas fuel to marketable gaseous fuels are briefly characterized.

Secure energy supply in 2025: Indonesia's need for an energy policy strategy

Indonesia as an emerging country with one of the fastest growing economies requires sufficient supply with energy for national development. Domestic energy production cannot satisfy the domestic demand, and the deficiency necessitates growing imports. The present energy mix consists of 96% from non-renewable sources, i.e. fossil fuels, less than 4% from renewables. Government Regulation 5/2006 aims at increasing the proportion of renewable sources to 17%. Two scenarios for the energy situation in 2025 have been elaborated and are discussed. An overall energy policy strategy and regulatory framework covering non-renewable and renewable resources are crucial for securing energy demand.     

Renewable energy in the Palestinian Territories: Opportunities and challenges

The Palestinian Territories relies on Israel for 100% of its fossil fuel imports and for 87% of its electricity imports. Total energy consumption in the Palestinian Territories is the lowest in the region and costs more than anywhere else in the Middle East. The purpose of this paper is to present the current energy situation in the Palestinian Territories, evaluate the potential of renewable energies in meeting part of the energy demand and discuss the challenges and benefits of using these types of energies. It is shown that the main renewable energy sources in the Palestinian Territories are solar, wind and biomass. Using the available renewable energy sources in the Palestinian Territories may significantly decrease the energy reliance on neighboring countries and improve the Palestinian population's access to energy. It is estimated that solar sources have the potential to account for 13% of electricity demand and wind energy for 6.6%. The conversion of animal waste into biogas has the potential to meet the needs of 20% of the rural population. The conversion of unused agricultural residue into biodiesel could replace 5% of the imported diesel.     

Rural household energy consumption with the economic development in China: stages and characteristic indices

This paper discusses history variance and general features on rural household energy consumption with the economic development in China. Energy shortage has been a long-standing problem in rural areas of China. The average effective energy consumption was 0.46–0.54 kgce per day per household in the 1960s and 1970s. The reason for this is that the rural household energy supply mainly relies on the available amounts of local natural energy resources. The problem of cooking fuel shortage was basically solved in the early 1980s since more straw and stalks were produced due to the rapid development of agriculture. The process of energy commercialization also started from the early 1980s due to the availability of coal, fuel oil and other energy sources in the market, and the reconstruction of rural power supply network. Energy consumption was 369.8 kgce per capita with 30% of commercial energy consumption and the effective heat per capita per day was 0.64 kgce in 1995. A closer relationship was found between household energy consumption level/structure and family income along with the economic development. This paper analyzed the rural household energy consumption of three typical regions, i.e., out-of-poverty, well-off and rich regions, in terms of effective heat per capita per day, percentage of commercial energy consumption in total effective heat, electricity consumption per capita and room temperature of northern areas in winter.     

National strategies for stimulating the use of bioenergy: policy instruments in Sweden

This study examines strategies of national energy policy, focusing on measures taken from the 1970s onwards for increasing the use of bioenergy in the Swedish energy system. Emphasis is given to analyses of how administrative policy instruments such as the Building Act, which regulates the use of natural resources, and the Wood Fibre Act have affected the woodfuel market for the district heating sector. The government can influence changes in three principal areas of the energy system: energy use, industrial structure, and energy production. The tools the government may use to exert its influence are: support to research and development, support to demonstration and information dissemination, administrative policy measures, and economic incentives. These instruments may be applied separately or in combination. Knowledge about how these instruments affect the development of the energy sector is fragmentary; it derives more from empirical observation than from analysis. A systematic evaluation of the separate and combined instruments that have been used would increase the possibility of correctly assessing the national energy policy. Nevertheless, practical experience and the analyses that do exist indicate that: (1) research and development are necessary prerequisites for developing the energy system even though results can not always be achieved in time to meet the need for fast results; (2) economic policy measures are comparatively easy to administer, and energy taxation has largely met its goals. With investment support, markets can be skewed and development can be hindered if existing technology is subsidised; (3) administrative policy instruments are cumbersome to administer and frequently do not achieve their purpose.     

Policy issues in improving energy efficiency

Today many urgent policy issues need addressing within the overall topic of improving energy efficiency. Also, they need to be addressed at many levels in society, each level possibly requiring a different approach: the overall national economy; the national energy sector; the energy utility; and the energy consumer. This article looks at some of the more important common issues, which apply at all levels, and gives some options on how these issues might be addressed.     

Climate change and energy policy: The importance of sustainability arguments

It is the stated policy of the UK government to reduce emissions of carbon dioxide by 60% by 2050. This policy, which goes far beyond commitments under the Kyoto agreement, was originally advocated by the Royal Commission on Environmental Pollution, of which the author was a member. Its acceptance was seen by many as a surprising development, possibly reflecting the strength of the underlying case. The target was developed by a three-legged argument which reflects the three components of sustainability:     

Energy saving and energy efficiency concepts for policy making

Departing from the concept of rational use of energy, the paper outlines the microeconomics of end-use energy saving as a result of frugality or efficiency measures. Frugality refers to the behaviour that is aimed at energy conservation, and with efficiency we refer to the technical ratio between energy input and output services that can be modified with technical improvements (e.g. technology substitution). Changing behaviour from one side and technology from the other are key issues for public energy policy. In this paper, we attempt to identify the effects of parameters that determine energy saving behaviour with the use of the microeconomic theory. The role of these parameters is crucial and can determine the outcome of energy efficiency policies; therefore policymakers should properly address them when designing policies.     

The single energy market and energy policy: conflicting agendas?

This paper examines the prospects for European energy policy in the light of the European Commission's proposals for an internal energy market. It reviews the history of attempts to create a common energy policy, concentrating on the 1980s. It considers whether or not there is a conflict between the traditional objectives of energy policy — limiting vulnerability to energy shocks — and the goals of the internal energy market — which would open the sector to market forces — by illustrating how the two agendas for energy policy address specific energy issues.     

Latest avenues and approaches for biohydrogen generation from algal towards sustainable energy optimization: Recent innovations,artificial intelligence,challenges, and future perspectives

The limited resources of fossil fuels and bio energies, along with the environmental pollution caused by their combustion, make it necessary to search for renewable and clean alternative sources and to optimize the available current energies specifically for required energy for using in buildings. This is mandatory for a solution of future energy production issues as huge consumption of energy in buildings and structures is unavoidable in buildings for instance China's higher education buildings consume huge amounts of bioenergy. Most of the attention in the production of biofuel has been focused on the use of plant biomass, agricultural waste, solid waste, and sewage treatment sludge. Today, there are renewable resources to replace fossil fuels such as biofuels for usage in buildings required energy; however, in the last decade, the cultivation of microalgae has been proposed as another option for biomass production. Utilization of algae biomass is more cost-effective than vegetable crops in terms of water consumption and cultivated area and reduces costs and greenhouse gas emissions by replacing fossil fuels. Artificial intelligence is a tool to help for this utilization and becoming much better in recent researches. Many types of microalgae, due to their high ability to consume organic carbon and inorganic nitrogen and phosphorus, can grow in different water environments, including urban, industrial, agricultural wastewaters, and wastewaters containing animal waste, which contain large amounts of organic and inorganic carbon. There are nitrogen, phosphorus and other elements that act as a biological filter that with extensive studies and inventing new methods, cost-effective production of algae-biofuels can be achieved. This review goals to run over the latest innovations and artificial intelligence approaches for biohydrogen generation from algal towards sustainable energy optimization and greener environment for buildings required energy. The current state of the art, existing and upcoming challenges, latest technologies, and solutions to overcome existing limitation are presented in details.
