In many parts of the world, drinking water is not available except through desalination. Most of these areas have an abundance of solar energy, with few cloudy periods. Energy is required for desalination and for producing electricity. Traditionally this energy has been supplied by fossil fuels. However, even in those parts of the world that have abundant fossil fuels, using them for these purposes is being discouraged for two reasons: 1) the emission of greenhouse gases from combustion of fossil fuels, and 2) the higher value of fossil fuels when used for transportation. Nuclear power and solar power are both proposed as replacements for fossil fuels in these locations. Both of these energy systems have high capital costs, and negligible fuel costs (zero for solar) Instead of these two primary forms of energy competing, this paper shows how they can compliment each other, especially where a significant part of the electricity demand is used for desalination.

Global warming is a pertinent issue and is quintessential of the environmental issues that the world is facing, and thereby, remedial actions and technologies that aim to alleviate this issue are of paramount importance. In this chapter, hydrogen has been discussed as an alternative energy that can potentially replace traditional fuels such as diesel and gasoline. The storage of hydrogen as a gas, liquid, and solid was discussed. The key issues in hydrogen storage were also highlighted. Furthermore, regulations and legislations concerning the emission of greenhouse gases from fossil fuels-based sources were discussed.

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.

As society continues advancing into the future, more energy is required to supply the increasing population and energy demands. Unfortunately, traditional forms of energy production through the burning of carbon-based fuels are dumping harmful pollutants into the environment, resulting in detrimental, and possibly irreversible, effects on our planet. The burning of coal and fossil fuels provides energy at the least monetary cost for countries like the US, but the price being paid through their negative impact of our atmosphere is difficult to quantify. A rapid shift to clean, alternative energy sources is critical in order to reduce the amount of greenhouse gas emissions. For alternative energy sources to replace traditional energy sources that produce greenhouse gases, they must be capable of providing energy at equal or greater rates and efficiencies, while still functioning at competitive prices. The main factors hindering the pursuit of alternative sources are their high initial costs and, for some, intermittency. The creation of electrical energy from natural sources like wind, water, and solar is very desirable since it produces no greenhouse gases and makes use of renewable sources—unlike fossil fuels. However, the planning and technology required to tap into these sources and transfer energy at the rate and consistency needed to supply our society comes at a higher price than traditional methods. These high costs are a result of the large-scale implementation of the state-of-the-art technologies behind the devices required for energy cultivation and delivery from these unorthodox sources. On the other hand, as fossil fuel sources become scarcer, the rising fuel costs drive overall costs up and make traditional methods less cost effective. The growing scarcity of fossil fuels and resulting pollutants stimulate the necessity to transition away from traditional energy production methods. Currently, the most common alternative energy technologies are solar photovoltaics (PVs), concentrated solar power (CSP), wind, hydroelectric, geothermal, tidal, wave, and nuclear. Because of government intervention in countries like the US and the absence of the need to restructure the electricity transmission system (due to the similarity in geographical requirements and consistency in power outputs for nuclear and traditional plants), nuclear energy is the most cost competitive energy technology that does not produce greenhouse gases. Through the proper use of nuclear fission electricity at high efficiencies could be produced without polluting our atmosphere. However, the initial capital required to erect nuclear plants dictates a higher cost over traditional methods. Therefore, the government is providing help with the high initial costs through loan guarantees, in order to stimulate the growth of low-emission energy production. This paper analyzes the proposal for the use of nuclear power as an intermediate step before an eventual transition to greater dependence on energy from wind, water, and solar (WWS) sources. Complete dependence on WWS cannot be achieved in the near future, within 20 years, because of the unavoidable variability of these sources and the required overhaul of the electricity transmission system. Therefore, we look to nuclear power in the time being to help provide predictable power as a means to reduce carbon emissions, while the other technologies are refined and gradually implemented in order to meet energy demand on a consistent basis.

The natural environment has its specific patterns that a human must take into account during realisation of any technical infrastructure of the world countries. Underestimating the dangers that can arise from natural phenomena has often serious consequences. Forsome constructions of technical infrastructure, especially their line constructions, there will be a high number of operational accidentswith extremely negative impact on the supplied regions with energy or drinking water. Other types of technical infrastructure forexample in nuclear power have a potential to create a natural emergency threaten the environment not only in the country of theirdislocation but also in the long term to change living conditions in entire regions.The following article deals with this issue in a suffcient basic range suggests chat ways and means to recognize the threat of danger andthen based on risk analysis to eliminate the consequences to an acceptable level.


Originally, coal was the main source of energy. It remains so throughout the 18th century during the period of the rapid industry development. Later on, oil and naphtha began to be used as energy sources and their usage expanded especially in 19th century. A special feature of the above mentioned fossil fuels is their long creation period – requiring millennia. They are a result of rotting of different plant and animal kinds. In comparison to the period of their formation, the period of their utilization is far shorter. In accordance with a number of existing statistics about 2050 year it may be talked about a depletion of the liquid fossil fuels, also, the world coal supplies are considered to last within the next 200 years. Therefore, the development of nuclear power engineering is considered to be one of the alternatives to generate energy. Recently, the nuclear power energy generation has been denied in many countries because of the risks associated with its generation and because these risks have been confirmed by serious accidents throughout the World. The storage of worked nuclear waste is also a problem and risky. The renewable energy sources are another possibility to generate energy.

Dairymen now have an alternative source of energy to assist them in efficient production of milk. Solar energy is being used to heat water and to space-heat milk houses and milking parlors. Used in conjunction with standard heating systems, solar systems can supply from 30 to 70% of the water- and space-heating requirements on a dairy farm. Tax incentives and rising costs of electricity and fossil fuels are making solar energy systems economically feasible for the modern dairyman. During the 1970s the world has come to recognize the reserves of fossil fuels used for energy are limited. The “energy crisis” caused these sources of energy to spiral in cost. Today, alternate sources of energy are being investigated and some are proving to be economically feasible.

The combustion of fossil fuels causes the emission of greenhouse gases such as C02, methane and NOx. The use of natural gas in place of oil and coal can help indeed to reduce greenhouse gases emission because natural gas is the cleanest of fossil fuels. Its non-pollutant character offers it extremely favourable prospects. World consumption is bound to increase rapidly, from 2120 Bern in 1991 to 3100-3500 Bern in 2010. Expanding world output will not raise any problems of resources because natural gas is an abundant energy source. However, gas production and transport costs are going to rise due to increasing distances between main gas reserves and consumer markets. The financial constraints will be the major factor limiting the growth in natural gas trade. And new solutions would have to be found in order to implement today the projects required in the long-term.

Scientists have been paying more attention to the shortage of water and energy sources all over the world, especially in the Middle East and North Africa (MENA). In this article, a microgrid configuration of a photovoltaic (PV) plant with fuel cell (FC) and battery storage systems has been optimally designed. A real case study in Egypt in Dobaa region of supplying safety loads at a nuclear power plant during emergency cases is considered, where the load characteristics and the location data have been taken into consideration. Recently, many optimization algorithms have been developed by researchers, and these algorithms differ from one another in their performance and effectiveness. On the other hand, there are recent optimization algorithms that were not used to solve the problem of microgrids design in order to evaluate their performance and effectiveness. Optimization algorithms of equilibrium optimizer (EQ), bat optimization (BAT), and black-hole-based optimization (BHB) algorithms have been applied and compared in this paper. The optimization algorithms are individually used to optimize and size the energy systems to minimize the cost. The energy systems have been modeled and evaluated using MATLAB.

Global warming and climate change coincide in their main causes, the massive emission of greenhouse gases, which retain heat in the atmosphere and on the earth's surface through the so-called greenhouse effect. The generation of electricity by means of fossil fuels is an important emitter of greenhouse gases (CO2, CH4, N2O), and halogenated compounds containing F, Cl, and Br. With the purpose of contributing to the construction of viable solutions to the current energy situation of the country and in the foundation of a sustainable future, the use of solar energy for the generation of electricity by means of solar panels represents an option. The purpose of this study is to describe and control the solar cell protection material Ethylene-Vinyl-Acetate (EVA), as a contribution to the Quality Assurance of solar panels, since the function of this material is essential for the protection of solar cells, which are a vital part of the solar panel. The tests performed were: Gel content, adhesion test, and durability tests. The results obtained were within specification according to IEC 61215. From this work it is concluded that it is important to continue testing the whole process and components of the solar panels in order to guarantee the useful life of the finished product, as well as to contribute to sustainable development.
