Drága-e a megújuló? – A hazai megújuló villamosenergia-termelés hatása a villamos energia árára (Is the renewable energy expensive? – Impact of the Hungarian renewable based power generation on electricity price)

A tanulmány arra keresi a választ, hogy a megújuló alapú áramtermelők támogatása csökkentőleg hathat- e a villamos energia nagykereskedelmi és kiskereskedelmi árára. Ez utóbbi tartalmazza a megújulók támogatásának összegét is. Számos elméleti cikk rámutatott arra, hogy nemcsak a nagykereskedelmi árak, hanem a kiskereskedelmi villamosenergia-árak is csökkenhetnek a drágább, megújuló alapú áramtermelők támogatása révén. A tanulmány során egy villamosenergia-piacokat szimuláló modell segítségével modellezi a szerző, hogy a különböző mennyiségű szélerőművi és fotovoltaikus kapacitás támogatása hogyan hat a magyarországi nagykereskedelmi és kiskereskedelmi árakra. _____ Impact of the Hungarian renewable based power generation on electricity price The aim of this paper is to answer the question whether the support of renewable power generation could decrease the wholesale and retail electricity prices. The latter one includes the support of renewables. Several studies point out that not only the wholesale, but the retail electricity prices could decrease when supporting the more expensive, renewable power generation. A model, which simulates the electricity markets, is used in order to analyse the impact of different level of wind and photo voltaic power generator support fee on Hungarian wholesale and retail electricity prices.

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?

Kihívások és lehetőségek a hazai megújuló energiaszektorban (Challenges and possibilities in the Hungarian renewable sector)

A megújuló energiatermelés szerepének erősödését figyelhetjük meg az utóbbi években, évtizedekben. A zöldenergiák iránti igényt három fő motivátorcsoporttal lehet indokolni: ellátásbiztonság növelése, környezetvédelem és gazdaságélénkítés. Ezek a szempontok együttesen a fenntartható fejlődést szolgálják, és egyre inkább előtérbe kerülnek mind az EU, mind pedig hazánk szintjén. Magyarország 2010 végén az EU által előírt, 2020-ra elérendő 13%-os megújuló energiaarányt meghaladó, 14,65%-os vállalást tett a Nemzeti Cselekvési Tervben, ezzel is kifejezve elköteleződését a zöldenergiák ösztönzése felé. A jelenlegi kapacitások több mint megkétszerezését igénylő cél a hazai megújuló energiaszektor számára érdemi lehetőségeket jelent, de ezek megvalósításához szükség lenne az ígért új zöldenergia-támogatási rendszer, mielőbbi életbe lépésére. ____ The role of the renewable energy generation is getting even bigger and bigger in the last years, decades. The demand for the green energy has three main motivators: energy security, protecting the environment and fostering innovation. These goals serve the conception of sustainable development, and their function is increasingly highlighted in the EU and in Hungary as well. The EU has prescribed Hungary to reach a 13% share of renewable energy sources in 2020, but in the Hungarian national renewable action plan we have aimed to top the EU request, and to reach a 14,65% in the renewable proportion. This shows that our country is committed to inspire the renewables. In order to reach this goal, Hungary has to more than double its green power plant capacity, which means great possibilities in the sector; but at the same time means challenges as well, because the new renewable promoting system needs to come into force as soon as possible.
