Megjegyzések:EU actions against climate change are rising energy prices, both have emphasized the use of renewable en- ergy,increase investments and energy efficiency. A number of objectives formulated in the EC decree no. 29/2009 by 2020. This document is based on the share of renewable energies in energy consumption should be increased to 20% (EC, 2009). The EU average is 20% but the share of renewables vary from one member state to another. In Hungary in 2020, 14.65% renewable energy share is planned to be achieved. According to the latest Eurostat data, the share of renewable energy in energy consumption of the EU average was 14.1%, while in Hungary, this share was 9.6% in 2012. (EUROSTAT, 2014). The use of renewable energy plant level is influenced by several factors. The most important of these is the cost savings and efficiency gains. Hungarian investments in renewable energy production usually have high associated costs and the payback period is substantially more than five years, depend- ing on the support rate. For example, the payback period is also influenced by the green electricity generated feed prices, which is one of the lowest in Hungary compared the Member States of the European Union. Consequently, it is important to increase the production of green energy. Nowadays, predictable biogas energy is an outstanding type of decentralized energy production. It follows directly that agricultural by-products can be used to produce energy and they also create jobs by the construction of a biogas plant. It is important to dispose of and destroy hazardous and noxious substances in energy production. It follows from this that the construction of biogas plants have a positive impact, in addition to green energy which is prepared to reduce the load on the environment. The production of biogas and green electricity is one of the most environment friendly forms of energy production. Biogas production also has other important ecological effects, such as the substitution of fertilizers, reducing its use in agriculture, which protects groundwater and surface water conditions and reduces the amount of greenhouse gases in the atmosphere. In the future more emphasis should be given to increase the effectiveness of existing technologies and other types of innovation could be expanded in energy production. It can be concluded that green energy investments can be rewarding if accurate planning is carried out before the investment.

Megjegyzések:Renewable energy resources have an important role by improving energy efficiency, thereby contributing to the sustainable and eco-friendly use of local energy resources. The rationalization of energy management and the im- plementation of innovative renewable energy projects can be an excellent tool in terms of both corporate, municipal and household levels to reduce energy costs.The Hungarian Power Companies Ltd. calculates that in Hungary new electricity generating capacity is needed for establishing growth in consumer demand and the replacement of old power plants. On 31th December 2013, there was 9 197 megawatts of installed electrical capacity in the Hungarian electricity system. By 2019, only 70% is expected to be available and by 2030, only 5 100 megawatts of capacity can be calculated. In addition to the replacement needs, the supposed increase in consumer demand also requires the establishment of new capacities (MTI, 2014).In this study, we examined one of Hungary's leading agribusiness companies' technical and other parameters. In the company's head office, hot water is produced by a solar panel. The roof-mounted solar cells heat a 200-liter reservoir of stored water. The daily use of water each day account to between 50 and 200 liters. Waste heat in the cooling system of the company's shop is utilized by using a group-agregator. Cooling is done with significant heat removal. This amount of heat or a portion of it could be recovered. Therefore, a heat exchanger was inserted into the cooling gas cycle which leads to a secondary water cycle with a 300 litre water tank. This solution produces hot water, providing the shop workers' daily hot water needs. Lighting was upgraded by replacing traditional high- performance 250-watt bulbs to 130-watt more energy-efficient light bulbs. The saving achieved is 120 watts per bulb. The energy-saving light bulbs last longer than the mercury-filled bulbs. It is important that the sockets be the same, so they do not have to replace the luminaires. In addition to saving energy it is also important to protect the environment. The mercury-filled bulbs are obsolete pollute the environment after disposal. The other plant head- quarters replaced 60 watts lamps to LED lamps. Also, lighting and the whole network will be replaced. The LED light's energy demand is 23 watts; therefore, barn lighting will result in savings of 2000 watts per hour. It is an important criterion of electricity to burden the electrical network only to the necessary extent. Therefore, services measure both the inductive and capacitive consumption. To avoid extra costs, factor correction capacitors are used. Therefore, reactive energy costs can be avoided.The world's energy resources are finite and it is increasingly more expensive to produce them. Therefore, we must strive to make renewable energy systems involve greater proportion of today's power structure. The company con- tributed to the requirement that the share of renewable energy sources by 2020 should reach 14.65% in Hungary. Green energy investment pays off in a long run for all businesses and it is a necessary economic development.
