The Past

The continuous development of the human society is in a close correlation with the increased consumption of electricity. In the past few years, the thirst for electricity at a global level, has led both to higher levels of pollution and the depletion of fossil fuels. For this reason, the issue of energy efficiency is a priority of energy strategy at national and EU level. In this context, a solution to the above problems is to increase the rate of production of electricity from renewable energy sources. Thus, the paper presents a study of wind energy as a source of renewable energy, their modelling and simulation for the Motru area.

Development Prospects

Human society faces the great challenge of drastically reducing greenhouse gas emissions while providing increased amounts of energy. Although the share of renewable energy sources has increased in recent years, fossil fuels are still widely used and burning them makes large amounts of carbon dioxide enter the atmosphere. However, renewable energy sources may not be able to supply in time enough energy to replace fossil fuels. Under the circumstances, the question arises as to whether nuclear energy could play a significant role in mitigating climate change. Although there is still confidence and support for nuclear energy, it is unlikely that this energy source will make a greater contribution to combating climate change in the coming decades. This study analyzes the current state of nuclear energy, as well as the development prospects in the context of climate change and risks to the environment and human health.

The Future

Motivated by energy security requirements and the desire to create a sustainable and safe environment, there is a growing need to transition gradually from fossil fuels toward new and emerging energy sources. The energy solutions of the future will require a significant amount of research and development, as well as increased awareness and acceptance of new and emerging energy technologies. Creating a highly educated workforce who will contribute to overcoming future energy challenges is a key component in bringing about this transition. One method of supporting workforce development in future energy solutions is to incorporate new and emerging energy technology directly into required undergraduate coursework. To this end, renewable energy projects were developed and implemented in a required introductory thermal science course in a mechanical engineering technology curriculum. The goal of the projects was to provide students with a deeper understanding of the need for, the advantages of, and the difficulties associated with renewable energy sources. The open-ended semester-long student projects included (1) research on the history and implementation of a renewable energy source, (2) development of an experimental application of the energy source in an energy conversion process, and (3) an economic analysis of the energy source in an assumed application or case study. This paper presents the design and development of these renewable energy projects, and informal and formal evaluation of the effectiveness of the projects over two years of classroom implementation. In addition, the link between the projects and select accreditation criteria for engineering technology programs is discussed.

Nigeria: Advancing the Cause of Renewable Energy in Nigeria’s Power Sector Through its Legal Framework

Oil Sector

Fossil fuels have been the mainstream of energy supply and a major source of foreign exchange earnings for the Federal Government of Nigeria, in spite of being an unrenewable and unsustainable source of energy. Nigeria is yet to tap into the full benefits after privatising its power sector, including the new global evolution in the energy sector and the resulting increasing demand for renewable energy sources, which some consider to be cheaper and more environmentally friendly than fossil fuels and their allied products. Energy security is a challenge to socio-economic development in Nigeria, due to the country’s over-dependency on fossil fuels. In terms of their impact and the potentials to preserve energy sources for longevity and sustainability, however, fossil fuels will come to be seen as an out-dated alternative in the power sector as the energy industry evolves. The implications for Nigeria’s oil sector will not be limited to dwindling crude oil prices. The concerns include poor energy utilisation in Nigeria and the need to promote energy efficiency and sustainability. They have led to the formulation of new energy policies around the world to serve as a vehicle for translating solutions into reality. This study has adopted a library-based legal research method with a comparative approach. The study reveals that it is the lack of a coherent legal framework with incentives for using renewable energy that is largely seen as the key issue causing slow uptake of renewable energy as an alternative source of energy in Nigeria. As well as the need for a coherent legal framework on energy and incentives for using renewable energy sources, the study advocates stringent enforcement of existing energy regulatory policies.

World Concept

Present energy use - largely dependent on fossil fuels - is incompatible with the sustainable world concept. In a sustainable world, energy sources are renewable and used in a way that damage to the environment is minimalized. This study investigates the possibility of a sustainable world using renewable energy sources. It appears that - when strict energy conservation is applied - such a sustainable world seems to be attainable. This requires, however, drastic changes in most parts of society.

Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.

Lignocellulosic Feedstocks

The use of renewable energy sources (biofuels), either as a component in the conventional fossil fuels, gasoline and diesel, or as a pure biofuel, contributes to energy saving and decrease of total CO2 emission. The use of bioethanol mixed with gasoline significantly decreases gasoline consumption and contributes to environment protection. One of the problems in the production of bioethanol is the availability of sugar and starch based feedstock used for its production. However, lignocellulosic feedstocks are becoming more significant in the production of bioethanol due to their availability and low cost. The aim of this study is to point out the advantages and shortcomings of pretreatment processes and hydrolyses of lignocellulosic feedstocks that precede their fermentation to bioethanol.
