“…The low-carbonization campaign in thermal power generation offers a primary drive for the whole power industry to cut down carbon emission. Based on the "Energy Ecology index" in [30][31][32], the present paper establishes the energy-environmental efficiency model to appraise the energy utilization rate of different thermal units and the effect that carbonization emission inflicts on the ecology, as expressed by Equation (15):…”

This paper introduces the "Energy-Environmental Efficiency" concept of building a low-carbon dispatch model of wind-incorporated power systems from the perspective of environmental protection and low-carbon dispatch promotion based on the existing economic environmental dispatch. A rolling auto-regressive and moving-average model is adopted to forecast wind speeds for the next 24 h and reduce the disadvantages brought about to the power system dispatch by wind speed fluctuations. A fuzzy satisfaction-maximizing approach is employed to convert the multi-objective decision-making problem in the low-carbon dispatch model into a single nonlinear one. Particle swarm optimization with a simulated annealing algorithm hybrid is used for better solutions. Simulation results show that the energy-environmental efficiency concept benefits the optimization of the proposed power system dispatch, and the proposed low-carbon dispatch model is reasonable and practical.

“…Conventional heat engines such as steam turbines are powered by burning fossil fuels and their typical efficiency ranges from 30-40% [3][4][5][6]. Hence, the rest of the heat as well as the byproducts of combustion causes an adverse effect on the environment such as global warming [7][8][9]. Some reports have identified the negative effects of waste heat including the forming of urban heat islands and global warming [10,11].…”

Sustainable energy sources are gaining popularity due to the ever increasing energy demand along with escalating costs and the environmental issues associated with the conventional sources of energy. Among the technologies available today, TEGs (Thermoelectric Generators) are intensively investigated due to their capability of harnessing electricity from waste heat, such as power plants, industries, automobiles and even human bodies. Our work focuses on the development of high efficiency organic thermoelectric materials to harness energy from ambient sources such as solar and domestic heat. In this present work, poly (3, 4-ethylenedioxythiophene)/(poly)styrenesulfonate (PEDOT: PSS) was post treated using nitric acid in order to increase its electrical conductivity, hence the efficiency. A maximum electrical conductivity of 197.51 S/cm was achieved which was approximately 115 times than that of the untreated material. Improvement of the electrical conductivity after post-treatment is due to the depletion of the non-conducting PSS after the acid treatment. Hence, it is concluded that it is an easy method to achieve comparatively good thermoelectric properties which can find its uses in flexible thermoelectric applications.

“…Since, by burning Hydrogen we obtain water vapor, it's recycling from water is achieved by an automatic integration of the water cycle in nature. Water vapors are not toxic, and from an ecological point of view, Hydrogen used as fuel represents an ideal energy carrier (Cârdu & Baica, 1999). This offers a real advantage for Hydrogen, if it is obtained from water using a technology where a primary nonpolluting energy source, such as solar, hydraulic or nuclear energy is utilized.…”
