Households have been pointed out as a significant source of air pollution and climate change. In Europe, the 60% of energy used by households is for space heating. The present work focuses on improving the knowledge on residential heating characteristics in Greece. The full causal chain, from the appliances used to the pollutants emitted, is examined at thelocal scale. A crowdsourcing approach was followed for the collection of the necessary data for performing the emissions calculations. With the use of a Geographic Information System (GIS), dynamic maps were produced for each Greek region, providing the information produced in this study in gridded form. In terms of energy demands, it was found that Greece relies mainly on oil and biomass and secondarily on gas and electricity. The use of biomass burning as a main heating fuel is quite high inthe colder and rural areas, while it is popular as a secondary heating fuel inthe urban areas. The residential heating period in Greece lasts from October to April and it is even shorter in southern Greece. In terms of emissions, CO and PM10 had the highest values since they are related to biomass burning. NOx emissions are mainly emitted by the oil burned in boilers.

We examine factors underlying hunting productivity among Inuit in Ulukhaktok, Northwest Territories, Canada. Specifically, we focus on the role of gasoline use as the main variable of interest—commonly cited as a crucial determinant of hunting participation. Over the course of 12 months, 10 hunters recorded their on-the-land activities using a GPS tracking system, participatory mapping sessions, and bi-weekly interviews. A multivariable linear regression model (MvLRM) was applied to assess whether factors such as consumables used (i.e. heating fuel, gasoline, oil, food), distances traveled, or the number of companions on a trip were associated with the mass of edible foods returned to the community. Results indicate that, despite being positively associated with hunting trip productivity when assessed through a univariable linear regression model, gasoline is not a statistically significant determinant of standalone trip yield when adjusting for other variables in a multivariable linear regression. Instead, factors relating to seasonality, number of companions, and days on the land emerged as more significant and substantive drivers of productivity while out on the land. The findings do not suggest that access to, or the availability of, gasoline does not affect whether a hunting trip commences or is planned, nor that an increase in the amount of gasoline available to a hunter might increase the frequency of trips (and therefore annual productivity). Rather, this work demonstrates that the volume of gasoline used by harvesters on standalone hunting trips represent a poor a priori predictor of the edible weight that harvesters are likely to return to the community.

The heating methods currently used at oil delivery sites and transfer stations on North China Oilfield include electric bar heating, fuel oil heating, gas heating, etc. The traditional heating methods have adverse effect on energy conservation and environmental protection. They have low energy efficiency of heating and produces great pollution to the environment. The air source heat pump technology uses the heat in the air as the low-temperature heat source and transforms it to the high-temperature hot water, which will later serve as a heat tracing for crude oil gathering and transportation. No combustion effluent is produced in operation and the energy-saving effect is outstanding with high social-benefit.

While we are struggling for energy independence and solving issues related to reducing heat loss, practical Europeans make full use of the biomaterial at hand to heat their own homes, office buildings, and even small businesses. For heating, fuel briquettes are used, which many Ukrainians still call «Eurodrova». Today, the production of fuel briquettes is a good profitable business, which you can do not only in the heating season, but throughout the calendar year. There is one positive feature in fuel briquettes, due to which more and more customers will appear every day: at a relatively low cost (wood waste is used), briquettes give a heat transfer of 19 MJ / kg, while firewood gives only 10 MJ / kg . With this calorific value, customers will need much less fuel to heat. At present, due to the difficult financial situation in the state, the undesirable vegetation in the form of shrubs that have flooded villages, fields and highways has become a big problem for society. Thus, the high-quality removal of unwanted vegetation is a relevant topic today. Felling shrubs and green spaces is a necessity that often occurs when “modernizing” a garden, putting in order on abandoned sites, clearing the area for construction, proper maintenance near roads and plantings in parks and botanical gardens, and also when landscaping in large cities and suburbs. For this purpose, a machine for cutting and chopping wood pulp was developed, with a trailed and mounted unit, which will allow collecting raw materials for wood chips, which can be used in the production of fuel briquettes, pallets for burning in boilers.

From the beginning of construction in the territory of Latvia there was an important issue that affected any house. How to get heat? As the territory of Latvia was always rich in forests, the answer was obvious - with firewood. This heating variant is also topical today. However, with the development of heating and the rhythm of human life, many classic heating, with wood, is not enough. Consequently, the author looks at the types of heating in Latvia's households and their development. As well as the consumption of wood fuel and its development trends. Wood specialty products, such as pellets, are nowadays a popular fuel. This article will be useful for those who are considering upgrading or converting a heating system that is going to build a new building, as well as producers of fuel and heating systems.
