The main elements of the pre-feasibility analyses of a certain plant are the initial investments, operations and usage costs, fuel costs, produced electric energy, interest norms, the life duration of the plant and some other indicators. LDC (Leveled Discount Cost) calculated with the following formula will be used to realise the cost-benefit analyses enabling the […]
From 29th to 31st May 2013 in Sofia (Bulgaria), the SEE Solar Exhibition and Energy Efficiency & Renewable Energy Congress and Exhibition will bring together top industry professionals. The Forum & Exhibition are a platform for market exploration of the Region, up-to-date technologies exposure and hot topics’ discussions. The business, state authority and the general public in South-East Europe are increasingly aware of the […]

One of the main goals of this study is to assess the energy amount that can be provided by the renewable energy. We stick on this study on the renewable energy technologies that can be applied in the household, service and agricultural sector. Taking into consideration the above goal the amount of energy […]
The energy sector is one of the most important ones in the country economy. The supply of the energy according to the sectors is based on hydro-energy, being considered as the primary energy source up to the fossil fuels, wood etc. The history of the traditional sources can be carefully considered for a further analyses […]
With solar energy, we distinguish usually two conversion types: solar thermal, solar PV (or photovoltaic solar energy) In this study we are focusing more on solar thermal energy. Solar thermal energy is the process where solar radiation is converted into thermal energy. The most common system is the solar water heater system (SWHS). The water is […]
Since a few centuries, mankind is able to use the wind power through the wind mills. As from the mid seventies, modern wind turbines have been developed with the aim to produce clean electricity. Technology for wind energy has tremendously advanced the last years, leading to (Ecofys BV 2006): Larger wind turbines Blades manufactured from […]
Geothermal resource consists of underground layers or springs that contain water with a temperature level which is enough to gain useful forms of energy. Usually, the water is heated through the higher temperatures in the earth core. The water temperate level can be used in the buildings for heating with low temperature directly or […]
Hydropower is a form of renewable energy that captures the potential energy of flowing water to convert it into electricity. A distinction is made between: Run-off river systems, where (a part of) the river flow is captured and led along a turbine. Pumped storage hydropower, where a lake is used as storage system in order to use […]
The term biomass covers a wide variety of both fuel and conversion technologies. Usually, the term biomass refers to woody or agricultural products being converted into useful energy through different conversion technologies (Ecofys BV 2006). Biomass often refers to solid materials such as wood, branches, industrial wood waste, urban solid waste and agricultural residues (agriculture […]
