Floods And Droughts

Global warming is increasing due to accumulation of greenhouse gases (GHGs) in the earth’s atmosphere. This is leading to devastating consequences causing floods and droughts in different areas of the globe. The exploitation and burning of fossil fuels on a tremendous scale is the main reason for rising global warming. The approach of sustainable development may help in controlling the rising temperatures. Hydrogen fuel is one such promising alternative clean fuel, that could change the scenario as per the vision of ‘Hydrogen Economy’. A combined approach of switching to cleaner and greener fuel with increased natural sinks for CO2 can provide a better solution to global warming.

Emission Of Greenhouse Gases

The global warming which preoccupies humanity, is still considered to be linked to a single cause which is the emission of greenhouse gases, CO2 in particular. In this article, we try to show that, on the one hand, the greenhouse effect (the radiative imprisonment to use the scientific term) took place in conjunction with the infrared radiation emitted by the earth. The surplus of CO2 due to the combustion of fossil fuels, but also the surplus of infrared emissions from artificialized soils contribute together or each separately,  to the imbalance of the natural greenhouse effect and the trend of global warming. In addition, another actor acting directly and instantaneously on the warming of the ambient air is the heat released by fossil fuels estimated at 17415.1010 kWh / year inducing a rise in temperature of 0.122 ° C, or 12.2 ° C / century.

The Impact

The impact on global warming of transportation and the infrastructure that supports it has been investigated over several decades. Anthropogenic heat and the generation of greenhouse gases from burning of fossil fuels and are major contributors to the warming process. An approach to mitigate these effects is discussed that considers semi-closed cycle gas turbine engines as a practical approach to slowing the release of greenhouse gases. Semi-closed cycle gas turbine engines have an inherent capability to reduce all regulated emissions while maintaining high efficiency, which in turn reduces CO2 emissions. With emerging technology development that includes higher component efficiencies, high temperature material development, improved control devices, and advanced combustor designs, aided by computational fluid dynamics, semi-closed cycle engines appear to have the potential to mitigate global warming with little economic or infrastructural impact. A specific semi-closed engine type is described, the high pressure recuperated turbine engine (HPRTE), along with the inherent mechanisms for control of NOx, CO, unburned hydrocarbons, and particulates. Results from a breadboard demonstration of the HPRTE are discussed, as well as emerging technologies which benefit this type of engine.

Cooking Oil

In recent decade, the demand for fuel as a source of energy has been dramatic. In fact, many oil and gas reservoirs are declining around the world. The use of fossil fuels such as oil, coal, and natural gas is contributing to the phenomenon of global warming. This is because it emits high quantities of carbon dioxide and other greenhouse gases to the atmosphere. Thus, many researchers and energy companies are investigating the production of an environmental friendly fuel that reduces the emission of greenhouse gases. Thus, bio fuel is one of the most obvious alternative sustainable fuels that can be produced from used vegetable oil and animal fats as well. Indeed, it has several advantages. For example, a biodegradable and a renewable energy reduces global warming phenomenon. Thus, this work is an attempt to produce a biodiesel fuel from chicken fat and waste cooking oil. Also, it was found that it is possible to produce biodiesel from chicken fat and waste cooking oils using transesterification reaction method. Furthermore, the process optimization was also adopted; for example, methanol to oil ratio. It has been found that the yield percentages of the produced biodiesel is increased by increasing the amount of methanol. In addition, the maximum conversion to ester could be achieved at methanol: oil ratio about 7:1. at 60 °C.

The burning of fossil fuels is an unsustainable activity, which is leading to an increase in greenhouse gases (GHGs) emissions and related global warming. Among sustainable energy sources, microalgae represent a promising alternative to fossil fuel and contribute to the achievement of important Sustainable Development Goals (SDGs). In particular, the potential contribution of marine microalgae to sustainable development is large as, among other benefits, they represent a carbon negative energy source and may be applied in many coastal areas around the world. Despite this, significant economic and technological improvements are needed in order to make microalgae biofuels viable on a large scale. This review aims to explore how and to what extent third-generation biofuels (marine microalgae, but also the latest advances in freshwater microalgae) can benefit the realization of these SDGs. From this study we concluded that the production of large-scale marine microalgae biofuels is not yet feasible from the economic perspective at a large scale. However, the cultivation of microalgae in seawater holds great potential for increasing the small to medium viability of this biofuel source. The possibilities for improvement along with the contributions to sustainable development lay the groundwork for continuing to study and apply the potential of sustainable production of microalgae bioenergy.

Gas Flaring

The effects of climate change differ from one region to another, as its effects are not the same in all regions of the world. The consequences differ from one region to another, according to its geographical location, or according to the ability of the region and its social and environmental systems to adapt to climate change or mitigate its effects. One of the most important factors of climate change is global warming. There are two major sources of global warming: natural and human. The human resource contributes by adding heat and greenhouse gases to the atmosphere because of the global use of fossil fuels, nuclear energy, burning of natural gas, coal, timber, and others. Natural gas flaring is one of the most important challenges facing energy sources and the environment globally and locally. In this study, light was shed on the flaring of natural gas in Basra Governorate and its impact on the environment and climate change. The results showed that burning natural gas in Basra contributes to changing the local climate by adding heat and greenhouse gases to the atmosphere, which led to an increase in the air temperature in the region. In recent years, it has reached (52 degrees Celsius), and it also affects air pollution by increasing concentrations of toxic gases in the atmosphere, and it is one reason for the increase in the number of cancer patients in Basra Governorate. And there was a strong positive correlation between increased gas burning and an increase in cancer cases.

Smart Grid Technology

Environmental destruction that is marked by high CO2 level or greenhouse gas emissions due to excessive use of fossil fuels is a serious challenge that must be minimized immediately. One of the most prominent impact is the destruction of natural ecosystems such as forest fires due to very high temperature, rising sea level, flash flood, melting of iceberg in the north and south poles and uncertain natural climates. From the energy sector that contribute most to global warming is the power generation sector. Currently there are still many power plants that use fossil fuels such as petroleum and coal as the main source of turbine drive in generating electrical energy. The burning results certainly produce CO2 gas that contributes to increase levels of global warming. In response to the crucial issue, developed countries make an effort to reduce the impact of greenhouse gases by conducting research and utilization of renewable energy as an environmentally friendly source of energy such as wind energy and solar energy. Renewable energy is capable of generating electrical energy without generating and increasing greenhouse gases. Current renewable energy utilization trends continue to increase which contributes to the birth of the smart grid concept. So the introduction of smart grid technology is a necessity to reduce the impact of global warming while encouraging efficiency, reliability and effective governance in the supply of electrical energy.

Energy From Waste

Considering the confrontation of waste disposal and minimizing Green House Gas (GHG) emission, technologies of Waste To Energy (WTE) production seem appealing. It provides one key solution for two major concerns regarding energy crisis and waste management. Energy from biomass can be seen as a promising alternative for fossil fuels, which are getting scarce and more costly day by day. Since a significant amount of organic waste from agriculture, industries, and community sources is collected annually, it can be convertible to useful energy forms like biohydrogen, biogas, bioalcohols, etc., through various Waste-To-Energy Routes (WTERs) for sustainable development. The adoption of this WTE technology will help the world not only in saving the traditional energy resources, but also in reducing GHG emission, and lowering environmental impact. With all these advantages, WTE industry is expected to experience a noticeable growth in the coming years and make greater contribution in supplying renewable energy. The review presents the technical, economical, and environmental aspects of various WTE techniques and focus on the benefit that this thermochemical conversion is a step forward towards sustainable development.
