| Situado na Zona da Mata pernambucana, o município de Tracunhaém tem como principal atividade econômica a cerâmica artesanal. A arte ceramista do município conta com renomados artistas, o que faz da cidade um dos maiores centros de excelência na arte da modelagem do barro no país. Pernambuco abriga parte de dois biomas importantíssimos para a biodiversidade do planeta, a Mata Atlântica e a Caatinga, apresenta preocupante estado de degradação ambiental.Os impactos variam desde pequenos focos de desmatamentos, até áreas em processo de desertificação. Este trabalho analisa a demanda por biomassa florestal pelos artesãos de Tracunhaém, em Pernambuco. As atividades desenvolvidas pelos artesãos apresentam um grande potencial impactante, pois além de utilizarem a... |

| Összességében megállapítható, hogy Magyarországon az elmúlt fél évszázadban rendkívül megnőtt az energiafelhasználás, ami többnyire a fosszilis tüzelőanyagokból nyert energiára alapult. Ez arra készteti a jelen és a jövő kor társadalmát, hogy törekedjen a rendelkezésre álló megújuló energiaforrások felhasználásának előtérbe helyezésére, melyek használata a fenntarthatóság és a versenyképesség szempontjából sem elhanyagolható, hiszen ismert, hogy napjaink egyik kritikus költségtényezőjét adják az energiaköltségek. A megoldásban jelentős szerep hárul a vidéki társadalmakra, mert hiába történik az energiafelhasználás zöme az urbanizált területeken, az energia-előállítás, kitermelés a vidékre koncentrálódik. A fosszilis tüzelőanyagok korlátaiból adódóan új... |

| ABSTRACT Solar energy as a form of electric power generation is gaining ground in Brazil, being the subject of worldwide discussions on sustainability. The electric energy, a right of all citizens, represents a consumption of natural resources on a large scale. State schools in Paraná invested more than R$ 46 million to guarantee electricity and thus provide essential running conditions to the system in 2016. Through open data, 15 schools from "Regional Administrativa do Cajuru", in Curitiba/PR, were evaluated in consumption and expenses of electric energy from January to May of 2017 and a solar photovoltaic system was dimensioned to supply the demand of each school. From that, it was estimated the total saving from the electricity that would no longer be... |

| ABSTRACT The aim of this study was to evaluate the energetic potential achieved by the application of phyto-regulators to sweet sorghum cultivars. A randomized complete block design was used. Experiments were conducted using two sweet sorghum cultivars (BRS 508 and BRS 509), fourphyto-regulators (ethephon, ethyl-trinexapac, glyphosate, and sulfometuron-methyl), and a control; four replicates were performed 70 days after sowing, at the beginning of the flowering phase of the plants, with the aid of a CO2-pressurized coastal sprayer. The plants were harvested after 40 days, with the stems being cleared at the height of the apical bud, and were subjected to grinding for the extraction of broth. The following analyses were carried out: chemical (total... |

| Our aim was to establish the specific objectives and toolkit of eco-energetic marketing targeting the North Hungarian region, through a primary survey of 600 persons. Our research objective was to examine – taking the region’s economic and social circumstances into consideration – what conditions, consumer reception, and affinity is needed to gain competitive advantage with the involvement of renewable energy sources, and also to point out the characteristics of how the population currently uses energy, its mode and satisfaction level. During the examination of consumers’ familiarity level with renewable energy sources we observed the dominance of solar, hydro, and wind energy, nevertheless, their knowledge about these renewable energy sources was rather... |

| Pakistan is facing severe energy crises from the last decade resulting daily electric blackouts from 8 to 12 h. The limited fossil fuel reserves and its environmental consequences have led to boost research and development of alternate energy resources. A huge amount of fossil fuels and electricity is being consumed for the generation of low to medium temperature heat energy for domestic, residential, agro-industrial and processing units. This low to medium temperature heat energy required can easily be fulfilled using solar collectors. This paper focus on the development of a flat plate collector using local infrastructure to reduce its initial cost. The collector consists of a window glass, absorber plate coated with black matt paint, copper tubes, inlet... |

| This article presents current investment and operating costs of ethanol and biodiesel plants for alternative prices of feedstock. The price of these two fuels is estimated for alternative prices of crude oil with the existing renewable fuels policy. The excise tax credit, currently $0.51 per gallon of ethanol and $1.00 per gallon of biodiesel, is a major contributor to the fuel price and profitability of these industries. The analysis demonstrates how the crude oil price, feedstock price, and excise tax credits interact to impact profitability of these industries |

| This study determined the effects of temperature and time on oil extraction from indigenous freshwater microalgae– Dictyosphaerium, Chlorella, Desmodesmus and Cosmarium species, cultured in fifteen 2-litre column photobioreactors (PBR) (three per specie). Growth and specific growth rates for the mixotrophic>autotrophic cultivation of the species. Oil was extracted from the dried microalgae species at temperatures ranging from 40 to 120 °C at 20 oC intervals and times ranging from 30 to 210 minutes at 30 minutes’ intervals, by accelerated solvent extraction method. Extraction temperature, time and type of microalgae species had significant effect (p < 0.05) on oil yield (temperature > time > type of species). As extraction temperature and time... |
