TL;DR: In this article, the authors apply energy analysis and economic analysis in order to assess the application of solar photovoltaics (PVs) in buildings and make a comparison both to electricity supply from centralised PV plants and to conventional electricity sources.

TL;DR: In this article, the performance of solar air heaters with chamfered repeated rib-roughness on the airflow side of the absorber plates was investigated and the experimental and predicted values of thermal efficiency lie within ±7% with a standard deviation of ±5.8%.

TL;DR: In this article, a study of the energy requirements for conditioning ventilation air and the yearly performance of a membrane-based energy recovery ventilator (MERV) in Hong Kong is carried out.

TL;DR: In this article, the design analysis of a two-tower, silica gel dehydration unit to dry one million standard m 3 of natural gas per day is presented and the effects of various operating parameters on the design of the unit are discussed.

TL;DR: In this paper, the influence of economic variables on the annual electricity consumption in N. Cyprus for the period of 1988-1997 has been investigated, using historical energy consumption, historical economic databases and multiple regression analyses.

TL;DR: In this paper, a 5 cm ID fluidized bed column is used to determine the minimum fluidization velocities of mixtures of biomass and sands, and equations are developed for predicting the U mf values of these mixtures.

TL;DR: In this article, a software tool for designing hybrid renewable energy systems was developed and applied for simulating a hybrid system with the above mentioned technologies in order cover the electricity and water needs of the Merssini village on Donoussa island in the Aegean Sea of Greece.

TL;DR: In this paper, a statistical analysis to examine the links between pollution and the types of kitchen and fuels is carried out for rural houses by first monitoring the indoor air quality (IAQ) followed by regression analysis of 418 households in Tamil Nadu, India.

TL;DR: In this paper, a life cycle inventory of steel based on exergy values is presented and a sensitivity analysis is performed in order to test how variations in some parameters affect the results of the total exergy accounting for the different steel production routes.

TL;DR: In this paper, a heat exchanger model for evaluating the thermal performance of an evaporator for a CO2 mobile air-conditioning system was developed, on the basis of the finite volume method, with emphasis placed on the air-side heat and mass transfer processes.

TL;DR: A detailed exergy analysis of a distillation system has been conducted in this article, where the main objective is to determine the distribution of exergy losses inside the column and the optimal distribution of heat to be transferred inside a column in order to produce the minimum overall exergy loss.

TL;DR: In this paper, the authors provided an assessment of the existing policy subject to the constraints of environment concerns and available, but limited, resources, and built a dynamic simulation model that captured the dynamics of the sectors underlying the electricity system.

TL;DR: In this paper, the authors used neuro-fuzzy programming to perform a comparison between the different electricity power generation options for Jordan, in addition to fossil fuel power plants, nuclear, solar, wind, and hydropower systems.

TL;DR: In this paper, the authors identify the major factors that have turned the California dream into a nightmare such as poor market design, market power, sustained demand growth not matched by new capacity, rising marginal cost, and financial insolvency, and propose remedies such as an alternative market settlement process, long-term contract, fast licensing and siting process for new generation and transmission, conservation and energy-efficiency, distributed resources, rate options, and debt restructuring.
