Abstract Projected temperature that will be felt by world community will increase 7.5°C hotter in 2070, meaning that world community is threatened to live in extreme temperatures an average of 34°C in next 50 years. This prediction can occur if a reduction in greenhouse gas emissions fails to be carried out simultaneously. On or hand, impact of soaring crude oil prices on world market has been felt by all walks of life so it is necessary to create alternative solutions to dependence of fuel to get through difficult times. In sea transportation sector, use of fuel for motorized ships is not only uneconomical but also not environmentally friendly. Dependence on fossil fuel energy has led to development of energy-efficient ship concepts that use alternative energy sources in moving ships. This is anticipated by use of solar energy in form of Electricalboats (Eb) which are applied as fishing vessels. This paper presents a study of efficient use of solar energy in Eb as a boat driver that does not utilize fuel for development of environmentally friendly fishing vessels. Technical analysis is done through testing ship model in Towing Tank n results are explored with Naval Architect ories. In conclusion, there is a potential for fuel consumption savings of up to 90% when compared to ships that only use conventional engines.

Fact Finding

The DESERTEC project, a European Union (EU) initiative to harness solar energy by means of Concentrated Solar Power (CSP) from Africa for use in Europe, shows the enormous potential that exists in alternative energy sources for the sub-region once there is political will. The Trans-Mediterranean Renewable Energy Corporation (TREC), a network of scientists and politicians who have taken it upon themselves to solve Europe’s energy problem using sun from Africa, conducted three studies which evaluated the potential of renewable energy resources in the Middle East and North Africa (MENA), the expected needs for water and power in EU-MENA between now and 2050 and issues relating to the construction of an electricity transmission grid connecting the EU and MENA (EU-MENA-Connection), with a formula to turn the North African desert sun into electricity and transport same to Europe. This paper harnesses the TREC fact-finding studies in order to estimate how much the same ideas can be applied in many other parts of the world, Nigeria in particular. Investigation reveals that this association exists with huge potentials for an energy-starved country like Nigeria in harnessing her abundant hot sun in the north, which could go a long way in meeting the energy needs in that part of the country and beyond. Other benefits include unlimited supplies of clean electricity, agricultural gains, and creation of new industries, new jobs and new sources of income.

Actuality of the problem. The article discusses the current level of use of alternative sources of electrical power in the world. The main areas of the global power development were determined, the statistical data of leading energy companies, analytical international organizations and financial institutions were analysed. For today, all civilized countries successfully switch to alternative energy sources: wind, solar energy, biofuels, etc. In addition, the use of solar energy is one of the most promising inexhaustible, renewable energy sources. The use of renewable energy sources replaces the traditional one, based on extractive technologies polluting the atmosphere with harmful emissions, and enhances the greenhouse effect, reduces the burden on the resource base and energy systems of countries and improves the environment. Sustainable development of the agricultural sector of the economy of Ukraine and, in particular, irrigated agriculture requires a reduction in energy dependence. In the structure of the cost of irrigation water, a significant share accounts for electrical power. That is why to increase the efficiency of irrigated agriculture, to ensure high and sustainable yields in the context of climate change, it is extremely important to reduce the cost of power consumption. The need to use alternative energy sources in the drainage complex of Ukraine as part of the implementation of the energy strategy of Ukraine, aimed at the transition to fficient use and consumption of energy resources is highlighted. The Institute of Water Problems and Land Reclamation deals with the investigations of measures and technologies to improve power efficiency to reduce the specific energy consumption for pumping water by pumping stations and to reduce the rate of power losses for water intake and water transportation by water supply paths. One of the effective measures to reduce power cost is the use of alternative energy sources, in particular solar energy. The economic potential of the measures for improving energy efficiency in irrigation systems wass estimated. Conclusions. The estimation showed that the use of modules of solar power plants installed above the surface of open irrigation canals will lead to lower energy costs in the face of a constant increase in tariffs, that is, it will help to increase the economic efficiency of irrigation, reduce the share of water resources in national energy consumption and have a positive environmental effect. The sale of surplus power to the energy system at “green” tariffs can significantly reduce the payback period for the modernization of the engineering infrastructure of irrigation systems.

Photocatalytic Materials

World is presently facing two major problems: Energy crisis and ever increasing environmental pollution as the fossil fuels used today are polluting the environment and these resources are limited only for a few coming decades. nanosized materials are being used these days to provide alternative energy sources to fossil fuels, which is environmentally clean also. The development of newer photocatalytic nanomaterials will enable us to produce and store solar energy in the form of hydrogen. Hydrogen has been advocated as the fuel of future and it can be produced by photo-splitting of water in presence of photocatalytic materials. nanosized photocatalytic materials have also been utilized in solar cells and photocatalytic reduction of carbon dioxide (a step towards artificial photosynthesis). Although, the use of nanosized photocatalytic materials has long miles to go to compete with present day technology (Photovoltaics and use of fossil fules), but there is lot of hopes from this kind of material in years to come. This chapter deals with use of nanomaterials in conversion of solar energy into electricity, photogeneration of hydrogen, and photocatalytic reduction of carbon dioxide. Presently, majority of photovoltaic power comes from bulk semiconductors, and only a limited use has been made of nanosized semiconductors, but there is likely U-turn in coming decades so that nanosemiconductors will have an edge over bulk semiconductors.
