This article presents the latest parameters and delivery methods that provide global solar energy and meteorological resources on the Internet. Over the past several years the number of parameters in the Surface meteorology and Solar Energy Data Set has tripled. The newest parameters include solar geometry, a suite of wind speed and wind direction data, diffuse, direct normal and tilted surface solar irradiance. Requests by users and recommendations by the renewable energy industry have prompted the growth.

Abstract The green economy emerges differently depending on each region particular features, as well as local economic strengths and weaknesses; solar energy however, represents the way regional and local natural potentials are valorized. The current paper brings to our attention aspects related to the economic and legislative factors influencing the use and territorial distribution of solar energy, as a component of the Romanian renewable energy industry at all territorial levels: the national characteristics of the use of renewable energy resources are highlighted through the analysis of dynamics of official statistical variables (National Institute of Statistics); at regional and county levels, the analysis highlights the territorial differences in the use of solar energy; analysis at local level reveals the environmental and socio-economic effects of the of solar energy use (i.e. photovoltaic parks), as indicated by the information provided by a questionnaire survey carry out in Giurgiu County (case study).

Concerns about global warming and climate change are generating interest in renewable energy measures with the purpose to minimize environmental impact. Promoting renewable energy production becomes indispensable since its represent a tiny fraction of energy consumed. The purpose of this study is to identify the performance determinants are divided in country specific advantages and firm specific advantages. Companies were selected from Bloomberg and filtered due to its information ava ilability from COMPUSTAT to construct a Panel Data structure. The results proved that both country level (shares of renewable and energy consumption) and firm level (market capitalization, employee growth rate and capital intensity) determinants were signi ficant in the renewable energy industry. Through the analysis, it’s possible to realize that return on assets it’s a performance measure with long term results, but unlike it, gross profit margin is variable that demonstrate short term results. We conclude that renewable energy industry has a great potential due to its results performed.

European countries are increasingly using renewable energy. Poland is an outsider of such solutions. The Polish energy sector is primarily based on energy produced from coal. However, environmental changes and regulations of the European Union are forcing the increased use of energy from renewable sources. Renewable energy is an industry that is still developing in Poland. At the same time, Poland is a country where the political decisions of the government over the last few years have resulted in a significant limitation of the possibilities of renewable energy development. These actions have also resulted in lowering the profitability of the currently operating renewable energy enterprises, especially those from the sector of small and medium-sized enterprises. An opportunity for SMEs operating in the renewable energy sector is to merge into industry purchasing groups. The aim of the article—and at the same time the research question—is: Is it financially safer for renewable energy companies to operate within purchasing groups compared to companies operating independently in this industry? Traditional ways of purchasing can be transferred to integrated purchasing systems, which will be created by purchasing groups associating renewable energy companies. For this purpose, the financial effects of the implementation and functioning of the purchasing groups in the renewable energy sector in relation to entities operating independently were examined. In the research of renewable energy SMEs, a comparative analysis of key indicators determining the possibility of continuing the activity of these entities was made. The following indicators were examined: current financial liquidity ratio, return on sales, operating cycle, cash conversion cycle, share of receivables in current assets, share of inventory in current assets, turnover ratios, level of receivables, liabilities and profitability. The scientific literature is dominated by studies on purchasing groups in the pharmaceutical and construction industries. Thanks to the research conducted, it has been indicated that the renewable energy industry can also improve its profitability, and thus the possibility of safe continuation of operations by extending the business model to inter-entity cooperation within purchasing groups. Increasing the efficiency of individual entities of the renewable energy industry within purchasing groups becomes particularly important during the COVID-19 pandemic. Statistical analyses and their graphic presentation present the significant impact on the safety and profitability of renewable energy entities in the form of purchasing groups.
