This paper aims to analyze the planning method of low carbon technologies. It is a follow up to our previous analysis of sustainability assessment of low carbon strategies concerning economic, environmental and social terms. Construction sector in Chongming Island, Shanghai is analyzed as a case study. Eleven main building energy saving technologies are evaluated, and CO2 emission reduction amount and required building areas in 2030 in Chongming Island are set by using Decoupling Theory and Goal Programming method. The minimum emission reduction cost is found as 7.87×108 RMB under low carbon scenario and 9.52×108 RMB under ideal scenario. Planning analysis result also show that the low carbon scenario is possible to meet as the required building area is around 20% of the estimated building area in 2030. The ideal scenario will require more intensive energy saving technology application as the building area requirement is found around 40%.

This study examines the occurrences of thunderstorm and rainfall as indicator of climate change in Potiskum and its environs through exploring the decadal recorded data of rainfall and thunderstorm. The data obtained were used to analyze the changes and activities of thunderstorms with rainfall, and thunderstorms without rainfall for each month of the 30 years under study. A descriptive and Inferential statistics was employed to determine the frequency and trend of thunderstorm activities as well as the intensity of rainfall. The analysis indicated that there was decrease in thunderstorm occurrences from first decade (1987 - 1996), second (1997 - 2006) to third decade (2007 - 2016). The results also showed that there was an increase of rainfall intensity in the third decade and decrease in second decade. The results further indicated that there was a climatic change in thunderstorm and rainfall activities in Potiskum and its environs during the study period, and this serves as good indicator of climate change in the study area. Therefore, it is recommended that Nigeria should develop capacity for research and data collection, to monitor climate change impacts, formulate and implement policies to protect natural resources, including forests, and conserve energy based on clean and low carbon technologies.

Low Carbon Technologies

To overcome the negative environemental impact of the actual power system, an optimal description of quasi-static electromagnetics relying on a reversible interpretation of the Faraday’s law is given. Due to the overabundance of carbon-free energy sources, this description makes it possible to consider an evolution towards an energy system favoring low-carbon technologies. The management for changing is then explored through a simplified linear-programming problem and an analogy with phase transitions in physics is drawn.

Transition Scenario

Currently, self-consumption and distributed energy facilities are considered as viable and sustainable solutions in the energy transition scenario within the European Union. In a low carbon society, the exploitation of renewables for self-consumption is closely tied to the energy market at the territorial level, in search of a compromise between competitiveness and the sustainable exploitation of resources. Investments in these facilities are highly sensitive to the existence of favourable conditions at the territorial level, and the energy policies adopted in the European Union have contributed positively to the distributed renewables development and the reduction of their costs in the last decade. However, the number of the installed facilities is uneven in the European Countries and those factors that are more determinant for the investments in self-consumption are still under investigation. In this scenario, this paper presents the main results obtained through the analysis of the determinants in self-consumption investments from a case study in Spain, where the penetration of this type of facilities is being less relevant than in other countries. As a novelty of this study, the main influential drivers and barriers in self-consumption are classified and analysed from the installers' perspective. On the basis of the information obtained from the installers involved in the installation of these facilities, incentives and barriers are analysed within the existing legal framework and the potential specific lines of the promotion for the effective deployment of self-consumption in an energy transition scenario.

Study Results

Remote communities such as rural villages, post-disaster housing camps, and military forward operating bases are often located in remote and hostile areas with limited or no access to established infrastructure grids. Operating these communities with conventional assets requires constant resupply, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. For example, a 2000-member isolated village in northern Canada relying on diesel generators required 8.6 million USD of fuel per year and emitted 8500 tons of carbon dioxide. Remote community planners can mitigate these negative impacts by selecting sustainable technologies that minimize resource consumption and emissions. However, the alternatives often come at a higher procurement cost and mobilization requirement. To assist planners with this challenging task, this paper presents the development of a novel infrastructure sustainability assessment model capable of generating optimal tradeoffs between minimizing environmental impacts and minimizing life-cycle costs over the community’s anticipated lifespan. Model performance was evaluated using a case study of a hypothetical 500-person remote military base with 864 feasible infrastructure portfolios and 48 procedural portfolios. The case study results demonstrated the model’s novel capability to assist planners in identifying optimal combinations of infrastructure alternatives that minimize negative sustainability impacts, leading to remote communities that are more self-sufficient with reduced emissions and costs.
