Feasibility and techno-economic assessment of stand-alone and hybrid RE for rural electrification in selected sites of south eastern Nigeria

The study assessed the feasibility and economic viability of solar and wind energy resources as sustainable electrical source for rural communities unconnected to the grid. Rural communities made up of 200 homes, a school and health centre were conceived. Specific electric load profile of 358?kWh per day, with 46?kW primary peak load and 20?kW deferrable peak load, was formulated to match the rural communities. The assessment of the design that will optimally meet the daily load demand with a loss of load probability of 0.01 was carried out by considering three stand-alone applications of photovoltaic (PV), wind, diesel, and a hybrid design of wind-PV. The result showed that a cost-effective alternative for power generation at the different sites surpassed the conventional diesel stand-alone system. Also, the embedded generation analysis showed that 5 of the 6 configurations yielded profits for a 10-year project life in line with the present national tariff order.     

Renewable energy scenario in Telangana

ABSTRACT

This article presents an analysis of the current situation of renewable energy in Telangana, India, and predicts the future of renewable energy resources in the state. In India, maximum power is generated using conventional energy sources such as coal and mineral oil. They highly pollute the atmosphere. If new power plants are to be set up, then the import of highly volatile fossil fuels is inevitable. Though nuclear energy is a good alternative to reduce fossil fuel consumption, it is equally hazardous to human life. Hence, the energy world should think of judicious use of renewable energy resources such as solar, wind, ocean, biomass, and geothermal energy. The R&D activities carried out in India in the past three decades have shown good progress in finding a feasible solution to the problem of searching new renewable energy resources. Telangana is the state committed to use the renewable resources in a better way to fulfil its electrical energy needs. This article also analyses the current energy needs of the state and forecasts energy consumption and production in the future with the aim of finding whether the state can continue on the path of development and augment its renewable energy resources.     

Legal framework and practice for environmental protection and application of green energy in China

ABSTRACT

In terms of the Chinese legal framework and practice on environmental protection, China evolves itself from basic control to systematic surveillance and from ‘belittlement’ to ‘coerciveness’; the complexity of the legal framework on energy application in China has been developed from rudimentary legislations on fossil resources’ utilisation to an entrenched design of legislative and policy instruments that is more emphatic towards green energy promotion. Today, under the influence of European experiences, China is carrying out a huge number of legal measures to realise the systematic coordination between environmental protection and energy application. Such coordination in China has primarily been ruled by state policies, rather than national legislations.     

Geothermal energy in China: Status,challenges, and policy recommendations

As a clean, renewable energy source with low carbon content, geothermal energy has the advantages of wide resource availability coverage, low environmental impact, low operating costs, and high reliability. For the development and production of more sustainable energy, geothermal energy has become one of the key areas of development in many countries. Geothermal resources are abundant in China and mainly distributed in the eastern region where the energy demand is the highest; therefore, the resources have the advantage of local development and consumption, which can alleviate the mismatch between resource distribution and demand in China's eastern and western regions. However, the development of geothermal energy started relatively late in China and has confronted many difficulties. This paper summarizes the status of geothermal energy in China and analyzes the existing problems with respect to policies and regulations, technological development, financial investment, and environmental protection. Some policy recommendations are put forward for promoting geothermal energy in China. This paper argues that the period of the “13th Five-Year Plan” is the opportunity for geothermal energy development. With the attention increasing, a series of policies to promote the development and utilization of geothermal energy could be introduced, and this resource could experience scaled development in China.     

Revealing expert perspectives on challenges to electricity Demand-Side Management in Pakistan: An application of Q-Methodology

Empirical evidence suggests that the implementation of Demand-Side Management (DSM) in developing countries falls short of its potential. This study aims at exploring the challenges to DSM development in a developing country by applying Q-methodology. The opinions of Pakistan's power system experts are analyzed quantitatively and qualitatively. From the analysis, three statistically different rationales, namely “inadequate policy and financial infrastructure,” “lack of institutional commitment,” and “low consumer motivation,” are responsible for modest DSM implementation. Based on the results, we recommend policy, institutional, and consumer engagement measures to foster DSM implementation in Pakistan.     

Uncertainty in estimating renewable energy utilisation potential: a case of solar thermal power generation in India

Estimation of renewable energy utilisation potential is important for identification of niche areas and prioritisation amongst different options. However, large variation in the potential estimates has been observed in different studies for the same renewable energy technology. This study is an attempt to analyse such a variation in the estimated potential for solar thermal power generation in India. From the analysis of three studies, it is found that the values of input parameters and the assumptions made substantially affect the estimated potential. The estimates of the utilisation potential depend upon the categories of wastelands selected, the chosen values of threshold DNI and wind speed as well as the criteria used for allocating suitable wastelands between solar photo-voltaic (PV) and thermal power generation. It is therefore critically important that reported values of renewable energy utilisation potential be interpreted and used with full cognisance of assumptions made and input parameters used in estimation.

Utilization of renewable energy in architectural design

Renewable energy does not simply equal to using a photovoltaic (PV) board. In addition to heating, ventilation and air conditioning (HVAC) engineering considerations, the design approaches of architects are crucial to the utilization condition and methods of renewable energy. Through profound comprehension of the relationship between renewable energy utilization and design approaches, we can achieve a dual-standard of building environment performance and esthetics.
