Life Cycle Evaluation of Energy Supply Technologies in China by Energy Chain Multi Layered Model

China has a large potential to reduce CO2 emission in the Asian region. In this study, life cycle analyses of energy supply technologies in China were evaluated for enforcing the clean development mechanism （CDM）. Wind power, integrated coal gasification combined cycle （IGCC）, natural gas combined cycle （NGCC）, and ultra super critical power plant （USC） were chosen as new power generation technologies. The system function of the developed model was enhanced to extend coverage to new technologies for power generation systems in China. CO2 intensities, energy profit ratios, and CO2 emission reductions are estimated based on the assumption that these power plants were constructed at Shanxi, Xinjiang, and Shanghai. Wind power showed the best results with regard to CO2 intensity and energy profit ratio. However, it also has some disadvantages with regard to the utilization factor and the lifetime. It is considered that wind power will become an important part of CDM activities as the utilization factor and the lifetime improve. An NGCC using a natural gas pipeline was found to be most advantageous in reducing CO2 emission. IGCC and USC were inferior to NGCC with regard to energy profit ratios and CO2 emission reductions.

Legal Conditions for Water Utilities Eco-innovation as Energy Smart Water Utilities

Welfare and green growth rest heavily on an appropriate supply of safe water, the provision of adequate sewerage, and on energy services. These services are interdependent, as water is an integral part of electric-power generation; it is used directly in hydroelectric generation, and it is used extensively for cooling and emissions scrubbing in thermoelectric generation. Energy is also an integrated part of water services, as satisfying water needs for supply, purification, distribution, and treatment of wastewater requires energy sources. Water and energy utilities are however regulated without a specific focus on the interdependency of the two sectors and the possibilities to ensure sustainable use of the resources and reduction of greenhouse gasses by a better coordination. The article explains the possibilities of sustainable consumption and production of energy in the water utilities. It highlights EU legal framework that makes coordination at national level possible, and it gives examples and concludes--on the obstacles for the water utilities＇ future as energy-smart utilities that exist at the national level in Denmark.

Does energy policy uncertainty matter for renewable energy and energy efficiency technologies?An affordable and clean energy perspective

Uncertainty can affect both macroeconomic indicators and the environment.Countries are implementing various energy policies to combat global warming,but these policies contain some uncertainties and contradictions.The environmental impact of uncertainties in energy policies is a research topic that has just begun to be investigated by researchers.This study examines the effects of energy policy uncertainty(ENERPU)on renewable energy R&D(RR&D),energy efficiency R&D(EER&D)and renewable energy consumption in the four countries with the highest RR&D expenditures(USA,Germany,Japan,and Spain).The study uses the novel multivariate quantile-on-quantile(M-QQR)approach from 2003m1 to 2022m9.The results of the study show:(i)The impact of ENERPU varies by quantile and country.(ii)ENERPU causes a decrease in renewable energy consumption and hinders RR&D expenditures.(iii)ENERPU increases EER&D.The Fourier quantile causality test confirms the robustness of the empirical results.Based on these findings,policymakers are recommended to minimize ENERPU and implement stable energy policies to develop the renewable energy sector and technologies.

A Randomized Longitudinal Double-Blind Clinical Trial on Long-Term Neuropathic Symptomatology Relief &Pain Analgesia

Diabetic neuropathic pain is one of the most difficult to treat with high levels of reoccurrence and a substantial increase with aging. It involves expensive hospitalizations, often resulting in an amputated lower limb. We explored a variety of methods treating neuropathic pain such as low-level laser, monochromatic near-infrared treatment, TENS, acupuncture and pulsed electromagnetic fields that demonstrated inconclusive, limited or temporary pain relief with minor or short-term improvements in mobility. Research conducted by ultra-low energy technologies reports pain relief and reduction of inflammation as a result of anti-oxidant electron donation transforming free radicals into stable molecules. We report the results of a randomized double blind one-year-long longitudinal clinical study on 10 diabetic mellitus (DM) subjects with chronic neuropathy, treated with ultra-low energy nanotechnology who experienced substantial long-term neuropathic pain relief. Importantly, pain analgesia and improvement in neuropathic symptomatology were not age-contingent. This contradicts past research postulating that age-accumulated inflammation and endothelial dysfunction can further exacerbate diabetic neuropathy. Importantly, a method offering age-independent, cost-effective, long-term neuropathic pain relief and increased mobility has major implications in reducing hospitalization time and overall expenses by offering a solution that enhances quality of life.

Comparative Analysis of Building Rating Systems and Occupant Rating Systems

To begin with, rating systems are a beneficial tool in determining the efficiency of a building’s ability to utilise its resources effectively. In this study, the two elements under comparison are the Building Rating Systems (BRSs) and Occupant Rating Systems (ORSs). The main objective of this paper is to be able to examine the most commonly applied international and national BRS and ORS and, based on that, discover the possibility of developing an integration of both the BRS and ORS into one rating system. Quite simply, a BRS is a method by which buildings are assessed and given a score based on numerous features such as the efficiency of each of the services, total energy consumption, and alternate options of consumption. There are various BRSs that are implemented globally, each with its own set of criteria and specifications. Thus, based on the analysis of the benefits and drawbacks of both types of rating systems, it could be deduced that a well-rounded rating system with all technical and non-technical aspects combined would be beneficial to both the efficiency of the building as well as the building occupants’ health and well-being.
