Non-condensable gases (NCG) in condensing geothermal flash plants have negative effects as they reduce heat transfer and thus deteriorate vacuum in condenser. Therefore, it is necessary to evacuate the condenser by vacuum pumps which substantially increases the parasitic load of the plant....

Japan's fish production volume in 2008 was 5.59million tons, it accounted for 4% of world's production and consisted of catch (4.40million tons) and aquaculture (1.19 million tons). For the far sea fishery, its' fishing grounds are in domestic and foreign countries' exclusive economic zone and...

The paper explores the relation between emitted CO2 in the atmosphere, asset expenditure, produced energy from renewables and energy consumption. ARDL model was developed on the basis of data for Bulgaria (2000 – 2018). As a whole the increase in asset expenditures leads to increase in emitted...

The huge territory and long distances between settlements (up to 700 km) determine the complex structure of the energy system of Yakutia. The average duration of the heating season in the region is 8-9 months, and 12 months in the Arctic. Electricity generation is carried out mostly by...

Nowadays, large parts of the world population (50-60%) are living in urban areas, which represent the most energy consuming systems (Buckley et al., 2009). Local governments are therefore asked to take new responsibilities in terms of energy management, adopting the urban scale as level of...

The study of the developed land and the energy consumption is part of a main project, which objective is the development of a model for the evaluation of the environmental and energy efficiency of the interaction (mobility) and land use structure (called as 'territorial functionality'), applied...
