Energy Challenge

The last decades fueled the energy challenge by the continuous growth of demand and strengthening of environmental restrains. How these challenges are addressed at global and national level is the main topic approached by the paper using as case study Romania. The availability of resources and how they compare with the current and growing needs of energy is analyzed and discussed. The analysis is taking in account the structure by primary energy sources and the dynamic on the last decades. Applying the same approach for energy imports it is calculated the degree of energy freedom and how this could be improved by considering the potential of renewable energy.

Nominal Condition

As of now, in the EU, all new buildings will have to comply with the requirements for nearly zero energy buildings (nZEB). Portugal defines limits for the maximum useful energy needs for heating and for the maximum primary energy needs and establishes that 50% of primary energy needs must be covered by local renewable energy sources, based on the dwellings’ nominal condition of use. However, the actual use is different. Thus, a simulation tool is used to assess thermal comfort and energy needs for different conditions of use of a dwelling complying with nZEB requirements. Eight different locations are chosen, covering all Portuguese climate zones. The nZEB requirements lead to unusually high levels of thermal insulation, especially in the coldest regions, so special care must be taken by the designers to avoid overheating in summer. Without using HVAC system, some discomfort is found but comfort is possible with low energy consumption. Furthermore, the compliance with nZEB requirements proved to be enough to ensure that a significant percentage of useful energy needs for heating, cooling and domestic hot water is supplied by local renewable energy sources. This is key in order to overcome the high rate of energy poverty in Portugal.

It is one of the most important issues of our time that meeting the energy needs for developing countries. Especially in recent years, the developed and developing countries emphasize the importance of resorting to current and renewable energy sources in order to be able both to feed them and to show sensitivity to the environment. It is an important tool in reducing external dependency that increased use of those resources in countries which is a country in an advantageous position in terms of renewable energy sources. From past to present with increased production and consumption and the point where the environmental problems reach, renewable energy sources is shown as a solution to this problem. Sustainable development makes an important contribution not only in quantity but also in quality to the economy. It is provided that enhancing human capital by performing technological development and sustainability of the environment by raising awareness of the environmental community and reducing of energy imports by applying renewable energy in energy production. It can be reduced its dependence on foreign energy with sustainable energy policies and R&D activities for the use of renewable energy sources where countries have the potential to be an ample supply. In light of this, it has been demonstrated that introduction of renewable energy sources should not be delayed in achieving sustainable development in economic, social and environmental dimensions. In this study, the strengths and weaknesses are evaluated in terms of sustainable development of renewable energy sources.

Family House

The paper presents the energy performance of a single-family house located in Domaszowice, the Kielce poviat. The analyzed object has been put into use in 2010 year. Due to the devices using non-renewable energy sources, installed in the building for the needs of hot tap water and central heating, for servicing, which human presence is necessary, two thermomodernizations were performed. The purpose of the calculations was to indicate the financial benefi ts, i.e. to reduce the costs of maintaining the home and to provide its residents with proper comfort of use of the building, bearing in mind also the health aspect. Changes have been proposed to reduce the demand for non-renewable primary energy of EP using renewable energy sources. As a result, the energy-efficient building that meets WT 2017 was obtained. The Certo 2015 program was used in the analysis.

Fossil fuels such as coal, oil, and gas meet most of the energy needs of people, but fossil fuels are unsustainable. The use of fossil fuels is one of the main causes of climate change and it has a serious impact on human health. In addition, these fuels are depleting, so the research and use of renewable energy sources such as wind, solar, geothermal or biomass is a necessity. In this paper, we mention some of the main reasons for promoting the development of renewable energy, the potential and the reality of renewable energy exploitation in Vietnam. In addition, we also outline the main reasons that hinder the development and exploitation of renewable energy sources in Vietnam.

Abstract Background There is no gainsaying about the importance of energy to the growth, development and socioeconomic well-being of any society. Photovoltaics (PV) have been identified not only as a means of meeting the energy needs of the Nigerian population but also as a tool in its national development. In this study, we reviewed the policy efforts of Nigeria in improving the renewable energy spread and the PV operations and utilization across the country. Results The technical audit of PV operations in Nigeria is evaluated using questionnaires administered in the 27 Local Government Areas in Imo State, as a case study. The component items in the latent variable scales of the audit have been tested for internal consistency using the Cronbach’s alpha. The good variable scale “Appropriateness for energy need” indicated a dissenting perception, whereas the acceptable variable scales “Adequacy in energy efficiency” and “Sustainability of PV project” indicated significant confidence in their perceptions. The perception in the energy need, which is associated with the limitations in PV utilization, is perceived as wrongdoings. Conclusions The whistleblowing policy is advocated as a germane measure to reduce or stop these wrongdoings and improve PV utilization and spread in Nigeria.
