The Relationship Between Renewable Energy Consumption, Net Energy Import, Greenhouse Gas Emission and Human Cap
58-71Views:169The measures to improve energy efficiency and increase of renewable energy production and consumption should be encouraged in the interest of sustainable development. Many factors can influence the use of renewable energy such as the level of economic development of an economy, nationals’ and the main economic actors’ environmental awareness, energy import dependency, ratio of the urban population, and government subsidization intensity among the others. The main purpose of this study is to examine the relationship between the share of renewable energy in the total energy consumption and net energy import as a percentage of energy use less production, greenhouse gas emission per capita and human capital using by OECD countries data from 1990 to 2014. The results indicate that there is a negative relationship between net energy import and renewable energy consumption, and also negative relationship can be shown between the amount of greenhouse gas emission per capita and renewable energy consumption. However, we identified a positive relationship between human capital and renewable energy consumption for energy importer countries above a certain level of human capital.

Current Challenges in the Regulation of CO2 Emission of Road Vehicles
738-742Views:222Today, as part of the fight against climate change, regulations on greenhouse gas emissions are gaining significantly higher attention. Our work focuses on the European Union legislation on carbon dioxide emissions from road vehicles, with special emphasis on the target values. Current changes in CO2 measurement methods, as important issues of the regulations, are also reviewed within this article.

The Role of Renewable Energy Sources in Energy Production and Use
678-688Views:331The role of renewable energies in energy management is growing both in the European Union and in Hungary. The use of renewable energy sources is already quite large (transport, heating, lighting, etc.) and it is advisable to deal with these energy sources in the year 2020. The use of energy from renewable sources can reduce greenhouse gas emissions and reduce dependency on the continuously problematic oil and gas market. A review of energy data over the last 10 years shows that renewable energy sources are playing an increasingly important role in the European Union. I support this finding by the fact that the share of energy from renewable sources in gross energy consumption has almost doubled in the last few years.

Green Sports Products – Environmentally Friendly Efforts of some Sports Equipment and Sportswear Manufacturers.
45-61Views:156In today's world, the issue of sustainability has become a cardinal problem on a global scale. The question of sustainability affects society, health, the economy, and the environment to a large extent. The examination of the environmental aspects of sustainability at the points where the sports sector interacts with the environment is considered a basis for research, and an increasing number of international studies and literature deal with this topic. Sports equipment and sportswear manufacturers operate through high numbers of multi-level global supply chains. They constantly strive to meet sudden changes in consumer demand, which results in high demand for raw materials and resources, waste and greenhouse gas emissions, and water consumption, all of which contribute to the most harmful environmental effects.
The aim of this study is to present the environmental protection measures of Nike, Adidas, and Under Armour, multinational manufacturers of sports equipment and sportswear, aimed at raw material usage, waste management, minimizing water consumption, and reducing their carbon footprint, which they are increasingly applying as part of their business strategy.

The green methanol - playing a role in sustainable energy management
249-258Views:162Global energy demand is constantly increasing, so the energy sources we use, and the efficiency of energy use are of paramount importance for the future of humanity. Methanol can play a key role in the sustainable use of natural resources, in the efficient and smooth transition from a fossil oil-based energy system as well as in reducing greenhouse gas emissions. Long-term thinking will result in an increase in the use of renewable energy sources, which will favour the spread of green methanol technology and thus the use of a carbon-neutral fuel. The raw materials for the production of green methanol may include municipal solid waste, agricultural waste, renewable hydrogen and carbon dioxide and the methanol has many uses, both as fuel and chemical feedstock. It also provides an opportunity to chemically store excess renewable energy from intermittent sources, thereby reducing dependence on fossil fuels. The price of electricity used for electrolysis is the main determinant of the economical production of green methanol, so the reduction of the cost of solar and wind energy greatly contributes to the competitiveness of carbon-based production.
