Abstract The aim of this study is to analyze the feasibility of the construction of 1-MW grid-connected solar photovoltaic (GCSPV) power stations at four locations of Jiangsu province, China. The economic, emission, sensitivity and risk analyses of the proposed systems are all performed using the RETScreen clean energy management software. The GCSPV system in Xuzhou is more economically viable than those in other regions under consideration, while this system in Nanjing is relatively less economically viable. The GCSPV power stations in Xuzhou have the largest annual Greenhouse gases (GHG) emissions reduction due to its largest electricity production from the proposed system. The sensitivity analysis results on NPV show significant variations due to the variations of electricity export rate (EER) and initial costs (ICs) parameters. The NPV of the proposed system increases from 707,589 $ to 2,046,766 $ with the increase of the EER, while the NPV of the system decreases with the increase of the ICs at the same of EER. The risk analysis shows the largest influence on the NPV of the project is the change of the EER with positive correlation, while the least impact on the NPV is the debt term with positive correlation.

This paper aims to show that sustainable behavior by firms may be impaired by regulatory restrictions. We challenge the assumption that regulation aimed at curbing greenhouse gas emissions (GHG) in the form of a target to meet the Country’s GHG emissions commitments will promote sustainable corporations. We argue that, in fact, such regulation may impair sustainability practices because it creates unintended consequences. This paper tackles the efficiency of the institutional framework chosen through the lenses of the analytical themes of fit, scale, and interplay, then we use a systems dynamic approach to represent how regulation in the arenas of energy efficiency and GHG emissions reduction may withhold competitive business outcomes and corporate sustainability schemes. We exemplify and simulate a single regulation scheme: a clean energy target for firms; and found that as a result of such scheme, the system is dominated by negative feedback processes resulting in lesser outcomes that would be better tackled by firms not being subject to the restrictions imposed by the regulation.

The production of palm oil in Malaysia generates large quantities of solid waste annually. A small fraction is currently utilized for steam and electricity production in palm oil mills. However, a large fraction is openly combusted or incinerated resulting in increased greenhouse gas (GHG) emissions. Gasification is considered to be a promising technology for converting bio waste into clean energy. It involves the partial oxidation of carbonaceous materials into gaseous products at high temperatures. This study is aimed at evaluating the thermal and physical properties of EFB, Shell and Fibre palm oil waste as gasification fuel. This is vital for the design, optimization and operation of biomass gasifiers. Consequently, the heating value (HHV), specific heat (c), combustion rate (CR), combustion heat (Q) of the wastes were determined. The results showed that the c, CR, Q displayed an increasing trend in the order EFB, Shell and Fibre. Furthermore, c, CR, Qwere significantly influenced by the organic and mineral content of the fuels. The results for heating value were EFB 17.97 MJ/kg, Fibre 18.71 MJ/kg and Shell 19.07 MJ/kg.

As the demand for renewable energy has grown, so too has the need to quantify the potential for these resources. Understanding the potential for a particular energy source can help inform policy decisions, educate consumers, drive technological development, increase manufacturing capacity, and improve marketing methods. In response to the desire to better understand the potential of clean energy technologies, several approaches have been developed to help inform decisions. One technology-specific example is the use of solar photovoltaic (PV) maps. A solar PV mapping tool visually represents a specific site and calculates PV system size and projected electricity production. This paper identifies the commercially available solar mapping tools and provides a thorough summary of the source data type and resolution, the visualization software program being used, user inputs, calculation methodology and algorithms, map outputs, and development costs for each map.

This paper uses an integrated assessment model to quantify the climate R&D investment strategy for a variety of scenarios fully consistent with 2°C. We estimate the total climate R&D investment needs in approximately 1 USD Trillion (all monetary values in this paper are given in 2005 US dollars using market exchange rates) cumulatively in the period 2010–2030, and 1.6 USD Trillions in the period 2030–2050. Most of the R&D would be carried out in industrialized countries initially, but would be evenly split after 2030. We also assess a "climate R&D deal" in which countries cooperate on innovation (while innovation is a broad topic, in this paper, we will be referring to its R&D component) in the short term, and find that an R&D agreement slightly underperforms a climate policy based on the extension of the Copenhagen pledges till 2030. Both policies are inferior to full cooperation on mitigation starting in 2020. A global agreement on clean energy innovation beyond 2030 without sufficiently stringent GHG emissions reduction policies is found to be incompatible with 2°C.

Akin to a public good, emissions reduction suffers from the ‘free rider’ syndrome. Although many countries claim that they are meeting their greenhouse gas (GHG) emissions reduction commitments, the average global temperature and GHG emissions continue to rise. This has led to growing speculation that some countries may be taking advantage of the system by effectively exploiting a range of loopholes in global agreements. Using a case study approach, we critically review the evidence from Australia, exploring how Australia has participated in global climate change negotiations and the way in which this emissions intensive country’s national emissions reduction obligations have been met. The findings suggest that: (1) successful negotiation to include Article 3.7 (‘Adjusting the 1990 Baseline’ or ‘the Australia Clause’) in the Kyoto Protocol significantly favored Australia’s ability to meet its First Kyoto Commitment (2008–2012); and (2) successful bargaining for the accounting rule that allowed carbon credits from the first commitment period to be carried over to the second commitment period of the Kyoto Protocol benefitted Australia by 128 MtCO2e. At the national level, a lack of bipartisan political support for an effective mechanism to drive emissions reduction has also been problematic. While the introduction of the Carbon Pricing Mechanism (CPM) in 2012 reduced emissions from electricity production from about 199.1 MtCO2e to 180.8 MtCO2e in 2014, a change of government led to the abolition of the CPM in 2014 and emissions from electricity production subsequently rose to 187 MtCO2e in 2015 and 189 MtCO2e in 2016 with adverse impacts in many sectors as well as Australia’s overall emissions. The current Australian government continues to undermine its commitment to mitigation and the integrity and credibility of its own emissions reductions policy, introducing a softer ‘calculated baseline’ for its own Safeguard Mechanism, which allows companies to upwardly adjust their calculated baselines on the basis of their highest expected emissions, permitting emissions in excess of their historical emissions. While disappointing in the context of the global emissions reduction project, Australia’s actions are sadly not unique and we also provide examples of loopholes exploited by countries participating in a range of other negotiations and emissions reduction projects. Such strategies undoubtedly serve the short-term political and economic interests of these countries; however, it is increasingly apparent that the cumulative impact of such tactics will ultimately impact the entire global community.

Biogas represents a promising source for the production of clean energy. The objective of this paper was to quantify the potential for the reduction of emissions to the environment during the production of electricity from biogas in comparison with environmental effects of the production of the same amount of electricity from fossil resources (coal from Kolubara basin and natural gas). Basis for comparison of environmental impacts in this work was the annual production of electricity in biogas plants of the total capacity of 80 MW. This study has shown that the annual production of electricity from biogas power plants of 80 MW results in: substitution of up to 840 kt of coal from Kolubara basin and 123.2 million m3 of natural gas; reduction in emissions of greenhouse gases in the range of 491.16 kt - 604.97 kt CO2-eq, depending on the energy efficiency of the process of electricity production from biogas; reduction in emissions of greenhouse gases up to 92.37 kt CO2-eq compared to the use of natural gas for electricity generation.
