Benign Energy Technologies and Financial Mechanisms for Achieving Net-Zero Emission Hospitals | Chapter 1 | Research Highlights in Science and Technology Vol. 6

 This unit aimed to review the sustainable strength technologies which maybe used in hospitals underrating their carbon emissions on account of energy use as well as review the existent financial tools that can support the investments of clean energy sciences in hospitals. This study is important because it indicates the benign strength technologies that can be secondhand for reducing the carbon footmark in healthcare organizations, helping bureaucracy to increase their energy security, self-reliance and resilience. In order to effectively defeat greenhouse gas diffusions, which are a serious general environmental issue, climate change must be checked. Compared to other organisations, hospitals and healthcare organizations require a lot of strength even if they mostly depend grid electricity and normal fuels.  Published literature indicates that various benign energy sciences have been used in clinics in developed and less-grown countries. These include: a) strength-saving technologies, b) energy from undepletable source technologies, c) low-element emission technologies, and d) sciences related with green conveyance. Most of them are reliable, mature and cost-adept. Their combined use results in lower carbon diffusions in hospitals. Any remaining diffusions can be offset accompanying the existing carbon compensating schemes. Investments in renewable energy sciences in hospitals can be eased by a number of different finance buildings. Conclusion: Hospitals can reduce their net carbon diffusions due to energy use to nothing with the help of a number of secure energy technologies double with carbon-compensating programmes, and the current financial structures can help to ease and fund the necessary energy grants. It should be mentioned that few of the energy technologies noticed in our study, including solar and wind strength technologies, can be secondhand in healthcare facilities only when the energy beginning is available in satisfactory quantities situated near to them. The current study provides to the clean energy transition of clinics reducing their dependence on nonrenewable energy. It indicates that the existing clean strength technologies can support energy remodeling in hospitals in a cost-efficient habit, helping them to advance both environmental and human energy.

Feasibility of De-carbonization of Air-transportation to and from the Island of Crete, Greece | Chapter 3 | Current Advances in Geography, Environment and Earth Science Vol. 1

 Clean energy transition is a critical and pressing issue in European islands that are contributing to the global effort to mitigate climate change. The Greek island of Crete is a famous tourist destination, with the majority of visitors arriving and departing by plane. The tourism industry dominates the Cretan economy, accounting for over half of all regional revenue. The current study's goal is to look at the possibilities of decarbonizing air travel to and from Crete. While other studies have predicted greater levels, air transportation accounts for 10.62 percent of total carbon emissions on the island. This is more than the expected share of carbon emissions from aviation, which accounts for 2-3 percent of global carbon emissions. Improvements in aircraft standards, usage of sustainable aviation fuels, offsetting carbon emissions, and adopting new rules limiting frequent use of air travel are all discussed as technological and non-technology means to decarbonizing aviation. The practicality and consequences of various strategies are discussed, implying that decarbonization will be difficult in the short and medium term. It seems unlikely that sustainable aviation fuels, such as biofuels and electrofuels, will be produced in sufficient quantities and at competitive rates anytime soon. New rules that raise the cost of flying and promote alternative, sustainable modes of transportation will have negative consequences for the island's tourism economy. On the other hand, decarbonization in other socio-economic sectors in Crete, such as power generation, heat and cooling production, and intra-island transportation, is easier than in air transportation.

Estimating the use of Distributed Electricity Generation Technologies in Tourism Industry | Chapter 7 | Challenging Issues on Environment and Earth Science Vol. 7

Because of their environmental and economic benefits, distributed power generating technologies are becoming more widely used in a variety of industries around the world. The current study's goal is to look at how these technologies, which use either fossil fuels or renewable energies, are used in the hotel business, as well as their characteristics, benefits, and downsides. Several distributed electricity generation technologies being investigated, including co-generation of heat and power systems. For electricity generation, some of them use renewable energies such as solar, wind, and biomass. Others are linked to different co-generation technologies, such as fuel cells. Many hotels have requirements. Technologies have the advantage of being able to meet practically all of a person's needs in terms of both electricity and heat. Solar photovoltaic energy, cogeneration systems, wind turbines, and fuel cells are all examples of distributed electricity generation technologies that are already in use in hotels. Their energy efficiency ranges from ten percent to ninety percent. Renewable energy technologies produce carbon-free electricity, whereas natural gas-fueled technologies produce electricity with low carbon emissions. Technology has benefits and downsides, and the use of each technology is dependent on the hotel's characteristics as well as the availability of renewable energy supplies in the area. The findings of this study are significant for the hotel industry because they show that they can use environmentally friendly distributed electricity generation technologies to meet their electricity and, in some cases, heating needs, reducing their carbon footprint and increasing their energy and environmental sustainability.

Recent Study on Optimal Economic Dispatch in Microgrids with Renewable Energy Sources| Chapter 3 | New Insights into Physical Science Vol. 8

 The use of microgrids receives more interest in the scientific community due to the opening of the energy market and the agreements for the reduction of pollution emissions, but the management of the delivery of electricity has new challenges. As a main component of designing a microgrid, this paper considers various distributed generation systems and the management of resources is described over a period through the proposed dynamic economic dispatch approach. The inputs are obtained by the model predictive control algorithm, taking into account variations in both the consumption trend and the capability of generation systems, including traditional and renewable energy sources. In addition , the proposed solution considers a consumer benefit programme involving the limitation of demand and the regeneration costs of the pollutants generated by traditional generating systems. Via a mathematical programming approach, the dispatch strategy aims to minimise to the minimum the fuel costs of traditional generators, the energy transactions, the regeneration of polluted emissions and, eventually, includes the advantage of reducing electricity demand by mathematical programming strategy, fulfilling all constraints. LINGO 17.0 programme (Lindo Systems, 1415 North Dayton Street, Chicago, IL , USA) implements the model. The findings show the suggested approach efficacy under various considerations through a study case. Improving the operation of the analysed microgrid is accomplished because various variables and potential scenarios of loads and renewable energy production capability are included in the proposed problem formulation. The results obtained by the proposed algorithm in 24 review periods during the study interval ensure that the performance adjustment level of each microgrid generator can be specified at the best possible value.
