Renewable energy sources (RES), such as solar energy, have been utilized in order to mitigate these environmental impacts. Here we try to answer the question as to why the development of RES among households in Poland is so weak. The survey was conducted in November and December 2015 within a project funded by the National Centre of Science. The main aim of the paper is to identify the factors that influence a household's willingness to install a renewable energy sources, in particular those factors related to level of education level and profession,. An additional aim of the paper is to make a typology of respondents-energy consumers, according to their relation to RES, on the basis of this and previous research. We propose a measure that divides the respondents into different groups according to their level of willingness to adopt RES. The results show that the greatest social acceptance of RES installation appears among: males, people in the age range of 30-49, people with secondary technical education, people living in detached houses, the owners of private companies and farmers. In addition, the results show that economic factors are the most influential in motivating households to install RES, since the respondents indicated the main benefits to be potential savings and potential profits. This study provides useful guidelines for policy makers to further promote the utilization of renewable energy sources among households.

It focuses on the identification of crucial elements of the business model for the development of start-ups and for their potential to create innovation, as well as the influence of network cooperation on the components of their business model. The canvas model is used to illustrate the research outputs. Additionally, the research aimed at identifying what start-ups expect from the networks in which they exist (e.g., technological parks) in terms of creating appropriate conditions supporting innovations. The study was done using three expert panels in which 28 start-ups participated. The research and its results are qualitative and are presented as a case study. The research was conducted by the authors in 2019 and concerns start-ups participating in cooperation networks, but its results could be interesting not only for start-ups, but also for everyone interested in the issues of cooperation between various entities and its potential to stimulate ...

We base our work on previous experiences and on the results of the research project named ‘Energy Development Strategy for Lower Silesia by Using Foresight Methods’ and carried out by our team from Wroclaw University of Technology (Poland). First of all, we present the idea of regulation in economies and the ‘bottom-up’ approach in programming regional development in the energy sector. The next part of the article concerns the key issues of foresight methodology and the range of its use. The results of our project are presented in the last part of this paper. The main idea is to show how foresight methods and main experts' methods, e.g. the Delphi method, can successfully support a ‘bottom up’ approach.

The purpose of the study is to assess the economic efficiency of the VPP model, which is influenced by several factors such as energy price and energy production. Ten scenarios for the VPP were prepared on the basis of the installed capacities of a hydropower plant (HPP), rooftop solar photovoltaic (PV), and energy-storage system (ESS), as well as weather conditions, in Poland. On the basis of technical conditions, it was assumed that the maximum power capacity of the ESS equaled 1.5 MW. The economic efficiency analysis presented in this paper demonstrated that, in seven years, the VPP will achieve a positive value of the net present value (NPV) for a scenario with 0.5 MW battery storage and rainy summers. Furthermore, sensitivity analysis was conducted on price f...

The VPP contains a hydropower plant (HPP), a photovoltaic system (PV) and energy storage system (ESS). The purpose of this article is to summarize the requirements for connection of generating units to the grid. Paper discusses the impact of the requirements on the maximum installed capacity of distributed energy resource (DER) systems and on the parameters of the energy storage unit. Firstly, a comprehensive review of VPP definitions, aims, as well as the characteristics of the investigated case study of the VPP project is presented. Then, requirements related to the regulation, protection and integration of DER and ESS with power systems are discussed. Finally, investigations related to influence of DER and ESS on power network condition are presented. One of the outcomes of the paper is the method of identifying the maximum po...

Therefore, the American, German, Finnish, Danish and Australian VPP’s business models are described in the article. The VPP is an IT structure which integrates different types of distributed energy sources, flexible consumers and energy storage with each other and with other market segments in real time through a smart grid. The VPP gives positive effects on electricity grid like ensuring energy security, improving grid stability and reliability, optimization of energy resources use, lowering the load - demand response, regulation of frequency, using operational reserves, management of peak demand. The business model is perceived as a method of increasing and exploitation of company’s resources for preparing new products or services for customers in order to obtain added value (expanding the competitio...

Users differ in their sex, age, economic status, knowledge about energy, their attitudes toward RES and pro-ecological behavior therefore our focus was on exploring segmentation criteria. The main determinants of willingness to install small-scale RES among households were assumed as segmentation criteria. The research identified the correlation between the households’ willingness to install RES and (1) socio-economic and energy awareness variables, (2) pro-ecological and pro-effectiveness behaviors variables. The main determinants of RES adoption were explored using empirical analysis with data collected by the survey among 960 households in Lower Silesia, a southwest region in Poland in November and December of 2015. The importance of the variables was verified by a logit model. The discovery of the user profile is vital to obtain knowledge about users of small-scale generato...
