“…However, the conventional energy system model has problems linked to the depletion of the world's non-renewable energy sources [3], the problematic dependence on fossil fuels and the emergence of environmental problems [4]. Main environmental issues related with electric energy production from fossil fuel combustion are: (a) acid rain; (b) ozone depletion caused by NO x emissions; and (c) the greenhouse effect or global warming [3,5].…”

“…Promotion of renewable energy is a key strategy for reducing greenhouse gas emissions, and thus contributes to the achievement of the climate change mitigation goals of the Kyoto Protocol. Due to their environmental benefits, and in order to diversify the energy supply, its development has been one of the central objectives of community energy policy [4]. Renewable energy technologies convert renewable sources to useful forms of energy such as heat, electricity, mechanical power or fuels.…”

“…In Europe, SHP is defined as below 10 MW [8]. In 2002, Galicia (region in the northwest Spain) had 81 small hydro stations with a total installed capacity of 169 MW, which represented 7.5% of installed small hydro capacity in Spain [4]. The region of Galicia is suitable for hydraulic power schemes and specially for SHP due to its climatic and topographic characteristics: an average annual precipitation of 1180 mm [9], a granitic geological composition and a relief which produce a wide river network [10], combined with an abrupt topography.…”

The renewable energy emerged as a solution to the environmental problems caused by the conventional sources of energy. Small hydropower (SHP) is claimed to cause negligible effects on the ecosystem, although some environmental values are threatened and maintenance of an adequate water quality should be ensured. This work provides a characterization of the water quality status in a river stretch around a SHP plant on river Lérez, northwest Spain, for four years after its construction. The ecological and chemical status of the water as well as the ecological quality of the riparian habitat, were used as measures of quality. Data were compared with the water quality requirements. The variations in the quality parameters were analyzed over time and over the river sections with respect to the SHP plant elements. Two years after construction, the temperature and dissolved oxygen values achieved conditions for salmonid water and close to the reference condition, while pH values were low. The Iberian Biological Monitoring Working Party (IBMWP) index showed a positive trend from two years after the construction and stabilized at "unpolluted or not considerably altered water". Quality parameters did not present significant differences between sampling points. The SHP plant construction momentarily altered the quality characteristics of the water.

In this study, the net balance of greenhouse gas (GHG) emission and energy of wheat and maize production systems in two farms in Khuzestan province of Iran was assessed. The results showed that totally wheat farming is more efficient than maize farming in terms of energy and CO2-eq indexes. The total energy requirement for maize and wheat farming was 92560.24 MJ ha -1 and 39624.15 MJ ha -1 , which caused the emission of 20191.47 and 7541.04 kg CO 2 -equivalent per hectare in maize and wheat farms respectively. Electricity, fertilizers and fuel were the most important pollutants of environment in terms of energy and gas emission in both farms. Theses inputs consumed 55.52, 22.62 and 6.44 % of total energy of maize and 47.32, 21.19 and 9.01 % of total energy of wheat farm and were responsible for the 88.60, 8.79 and 2.03 % of CO 2 -equivalent in maize and 86.54, 9.54 and 3.24 % of CO 2 -equivalent in wheat farms respectively. The results of this study also showed that the enhancement of 60.74 and 27.02 % in energy ratio and 46.06 and 27.87 % in CO2-eq index in maize and wheat farming can be expected using simple improving scenarios. , kar znaša 2,03 % ekvivalenta CO 2 pri koruzi in 86,54; 9,54 kg CO 2 ha -1 in 3,24 % ekvivalenta CO 2 pri pšenici. Rezultati te študije so tudi pokazali izboljšanje ob uporabi izboljšanega scenarija na 60,74 and 27,02 % v energetski bilanci in 46,06 in 27,87 % v bilanci CO 2 pri koruzi in pšenici.
