The use of methane as automotive fuel – a step to sustainable economy?

The introduction of CNG (Compressed Natural Gas) as automotive fuel began in Italy as early as in mid- 1930s, and ever since the Italian market has always been highly advanced in this regard. Many other countries followed, some of them quite recently, but nevertheless with impressive results. The appeal of this automotive fuel is based on the fact that compared to gasoline, diesel and LPG (Liquefied Petroleum Gas), CNG is cleaner and cheaper; even more so, this fuel is renewable – it can be produced locally from biogas. Despite its obvious benefits, CNG is barely present in Hungary. This article provides an insight into the topic, highlights obstacles to introduction and suggests appropriate governmental steps. The information is intended to support the activities and the decision-making process of governmental officials, municipalities, car-fleet managers, car dealers and their service departments.

Social acceptance of renewable energy: Some examples from Europe and Developing Africa

Current energy systems are in most instances not fully working sustainably. The provision and use of energy only consider limited resources, risk potential or financial constraints on a limited scale. Furthermore, the knowledge and benefits are only available for a minor group of the population or are outright neglected. The availability of different resources for energy purposes determines economic development, as well as the status of the society and the environment. The access to energy grids has an impact on socio-economic living standards of communities. This not fully developed system is causing climate change with all its related outcomes. This investigation takes into consideration different views on renewable energy systems — such as international discussions about biomass use for energy production, “fuel versus food”, biogas use — and attempts to compare major prospects of social acceptance of renewable energy in Europe and Africa. Can all obstacles to the use of renewable energy be so profound that the overall strategy of reducing anthropogenic causes of climate change be seriously affected?
