    Opis:
    Aim: The aim of this paper is to explore Energy Storage requirements and options to suit the needs of systems and transport fed from renewables. The variability of wind and solar sources in particular and the demand for transport energy are seen as key issues. Design / Research methods: The paper outlines the need for energy storage and compares the energy density and power density of a selection of storage options. Conclusions / findings: The results illustrate the difficulties of finding storage mechanisms to rival fossil fuels in both energy density and power density. Moreover finding the natural resources to provide sufficient storage will be a serious challenge even though the economic costs of storage systems are falling.. Originality / value of the article: The article demonstrates the importance of energy storage to the successful development of renewable energy systems, and of the economic and physical characteristics that such energy storage schemes should have. Implications of the research: Energy storage as a topic should be given a high priority for research and development. Limitations of the research: This article is not comprehensive and a review of best practice internationally would be a valuable extension to this work. JEL: Q42

    Aim: In the context of climate change this paper explores the value of models for evaluating energy costs by considering energy accounting and externalities instead of capitalistic economics.   Research methods: We test the hypothesis that the conventional economic model of the energy market can lead to inappropriate choices, and that those choices may be environmentally damaging. We examine energy accounting (energy return on energy investment), embodied energy and the incorporation of external costs as more valuable economic models.   Findings: This paper reviews existing economic tools and examines modifications, which, when applied to energy provision or efficiency and conservation of energy applications, may give more accurate information about investment, return and environmental damage. Energy accounting of schemes should be a preliminary requirement for all proposed energy schemes. Externalities are less readily applied, but as the costs associated with renewable energy are becoming competitive in conventional economic terms, they are less valuable than energy accounting.   Value of the paper: The paper concludes that a preliminary assessment of a proposed energy scheme should be undertaken using energy accounting and external costs to determine the true energy value. These models could be used to select the best environmental option. Indeed “energy uneconomic” schemes, which cost more energy than they deliver, should be abandoned in order to avoid unnecessary environmental damage. After this process, legislation and fiscal measures such as taxes and incentives could be applied to satisfy social and political imperatives. Examples of energy accounting in insulation and consideration of external costs in a proposed strategy to replace fossil-fuelled electrical generation in Indonesia are included in the paper.   Limitations: We have not considered the serious question of finite fossil fuel resources and feel that this would be a profitable line of research.

    Abstract: Aim: According to COP23, Climate Change threatens the stability of the planet’s ecosystems, with a tipping point believed to be at only +2°C.  With the burning of fossil fuels, held responsible for the release of much of the greenhouse gases, a sensible world- wide strategy is to replace fossil fuel energy sources with renewable ones. The renewable resources such as wind, hydro, geothermal, wave and tidal energies are found in particular geographical locations whereas almost every country is potentially able to exploit PV and biomass. This paper examines the role that changing climate could have on the growing and processing of biomass. The primary concern is that future climates could adversely affect the yield of crops, and hence the potential contribution of biomass to the strategy to combat climate change. Maize, a C4 crop, was selected for the study because it can be processed into biogas or other biofuels. Four different Nigerian agricultural zones growing maize were chosen for the study. Long-term weather data was available for the four sites and this permitted the modelling of future climates. Design / Research methods: The results of this study come from modelling future climates and applying this to crop models. This unique work, which has integrated climate change and crop modelling to forecast yield and carbon emissions, reveals how maize responds to the predicted increased temperature, change in rainfall, and the variation in weather patterns. In order to fully assess a biomass crop, the full energy cycle and carbon emissions were estimated based on energy and materials inputs involved in farm management: fertilizer application, and tillage type. For maize to support the replacement strategy mentioned above it is essential that the ratio of energy output to energy input exceeds 1, but of course it should be as large as possible. Conclusions / findings: Results demonstrate that the influence of climate change is important and in many scenarios, acts to reduce yield, but that the negative effects can be partially mitigated by careful selection of farm management practices. Yield and carbon footprint is particularly sensitive to the application rate of fertilizer across all locations whilst climate change is the causal driver for the increase in net energy and carbon footprint at most locations. Nonetheless, in order to ensure a successful strategic move towards a low carbon future, and sustainable implementation of biofuel policies, this study provides valuable information for the Nigerian government and policy makers on potential AEZs to cultivate maize under climate change. Further research on the carbon footprint of alternative bioenergy feedstock to assess their environmental carbon footprint and net energy is strongly suggested. Originality / value of the article: This paper extends the review on the impact of climate change on maize production to include future impacts on net energy use and carbon footprint using a fully integrated assessment framework. Most studies focus only on current farm energy use and historical climate change impact on farm GHG emissions.

    Aim:  In this paper we demonstrate an outline strategy for Indonesia to move its electrical generation from fossil fuels to renewable sources in order to reduce carbon dioxide emissions whilst avoiding excessive costs. The modelling here is based on assumed present fossil fuel generating plants. Design / Research methods:  We have modelled a representative electrical generation system based on burning coal, oil and gas, and by replacing retiring stations with photovoltaic cells and wind turbines we have considered the cost and carbon dioxide implications over a 30 year period. Additionally the modelling is extended to increasing the Indonesian installed electrical capacity. Conclusions / findings:  The results show that Indonesia could meet its carbon dioxide emission reduction targets in an economic way by a phased strategy of introducing renewable energy sources. These results are preliminary and will be refined in a future article where we will include the detail of actual existing power stations, with their capacity and anticipated end of life date. Originality / values of the article: There has been, and continues to be, a general resistance to the adoption of renewable energy. This paper shows  the economic benefit that accompanies carbon dioxide reduction thus presents a new aspect to the consideration of carbon reduction,  Implications of the research: Indonesia faces difficulties in providing electricity whilst meeting its climate change obligations. This research points to a viable economic strategy which may not only meet those obligations, but actually increase electrical provision across the country. Key words:  Sustainable development, climate change, carbon emissions, renewable energy   JEL: C51,L94,Q01,Q42   Doi:
