Abstract copyright UK Data Service and data collection copyright owner. To collect information on current energy use in council houses, concentrating on families in the Hull area, and to relate technical and behavioural data concerning domestic energy use. Main Topics: Variables Data was obtained on three types of house: pre-war improved, modern gas-fired radiators, and modern gas-fired warm air. Data collected included central heating usage, other heating, water system use, behavioural aspects of energy use, window opening and general ventilation, insulation appliance ownership, estimated fuel expenditure, patterns of home use, socio-economic details, temperature and weather data, and actual fuel expenditure. The data were analysed to obtain the main factors causing variations in fuel expenditure, and combined with technical data on house types in order to construct a predictive model of household energy use.

Today apartment dwellers generally tend to be individualistic righteously urban middleclass society in general. Unlike the situation in the neighborhood, where the level of socialization on the surrounding community is still quite high due to the surrounding community still likes hanging out with the neighbors, especially in the afternoon. Issues raised here is the lack of socialization that occurs between the residents in the apartment. Garden Living means “life park”. Garden is a garden that is as a place of socialization for residents and surrounding communities. Garden Living itself is to make the park as a place to socialize and interact with fellow residents of the apartment and the garden is also a gathering place for the general public. Lack of facilities to accommodate the occupants to socialize the reason the construction of an apartment that has an garden and is expected to become a place to socialize for the residents of the apartment. For the people who live around the apartment also will be built a public park so that people can still socialize and gather together. Taking the concept of Green Architecture or Sustainable Architecture, the building is minimal in consumption of natural resources, including energy, water, materials, and minimal negative impact on the environment. By the way of utilizing rain water and Deli river water and uses sunlight as a power source. 100406064

Global warming has become an increasingly important issue around the world today due to the rise of anthropogenic greenhouse gases emission, which gives several negative impacts on human life. There are some techniques have been studied and assessed i.e. physical mechanism by injected CO2 to the geological formations, chemical mechanism with artificial tree technology and biological mechanism by increasing the primary production through iron enrichment in high nutrient-low chlorophyll (HNLC) waters as well as mixing of water column below the sea surface. Those technologies, which are well known as Carbon Capture Storage ‘(CCS) technology, are expected to be applied to reduce the oncentration of anthropogenic CO2 in the atmosphere and to minimize the global warming. The Center of Environmental Technology, Agency for the Assessment and Application of Technology (BPPT) will carry out a research concerning CO2 reduction by a phytoplankton culture in a photobioreactor in three years. The main objective of this research is to assess the CO2 uptake capability of tropical phytoplankton. In this paper, we would showed the creteria and design to assembly a photobioreactor esspesially a air lift photobioreactor. To improve performance photobioreaktor, the materials included design criteria and the dynamics of fluids in fotobioreaktor have to considered propoerly. Other the hand, the selection of the most productive species and selection of appropriate media and economically also important to be done.

This study considered the current situation of solid and liquid biomass fuels in Finland. The fact that industry consumes more than half of the total primary energy, widely applied combined heat and power production and a high share of solid biomass fuels in the total energy consumption are specific to the Finnish energy system. Wood is the most important source of bioenergy in Finland, representing 20% of the total energy consumption in 2007. Almost 80% of the woodbased energy is recovered from industrial by-products and residues. As a member of the European Union, Finland has committed itself to the Union’s climate and energy targets, such as reducing its overall emissions of green house gases to at least 20% below 1990 levels by 2020, and increasing the share of renewable energy in the gross final consumption. The renewable energy target approved for Finland is 38%. The present National Climate and Energy Strategy was introduced in November 2008. The strategy covers climate and energy policy measures up to 2020, and in brief thereafter, up to 2050. In recent years, the actual emissions have exceeded the Kyoto commitment and the trend of emissions is on the increase. In 2007, the share of renewable energy in the gross final energy consumption was approximately 25% (360 PJ). Without new energy policy measures, the final consumption of renewable energy would increase to 380 PJ, which would be approximately only 31% of the final energy consumption. In addition, green house gas emissions would exceed the 1990 levels by 20%. Meeting the targets will need the adoption of more active energy policy measures in coming years. The international trade of biomass fuels has a substantial importance for the utilisation of bioenergy in Finland. In 2007, the total international trading of solid and liquid biomass fuels was approximately 77 PJ, of which import was 62 PJ. Most of the import is indirect and takes place within the forest industry’s raw wood imports. In 2007, as much as 21% of wood energy was based on foreign-origin wood. Wood pellets and tall oil form the majority of export streams of biomass fuels. The indirect import of wood fuels peaked in 2006 to 61 PJ. The foreseeable decline in raw wood import to Finland will decrease the indirect import of wood fuels. In 2004– 2007, the direct trade of solid and liquid biomass fuels has been on a moderate growth path. In 2007, the import of palm oil and export of bio-diesel emerged, as a large, 170 000 t/yr biodiesel plant came into operation in Porvoo.

As sentinels of climate change and other anthropogenic forces, freshwater lakes are experiencing ecosystem disruptions at every level of the food web, beginning with the phytoplankton, a highly responsive group of organisms. Most studies regarding the effects of climate change on phytoplankton focus on a potential scenario in which temperatures continuously increase and droughts intersperse heavy precipitation events. Like much of the conterminous United States in 2019, the Muskegon River watershed (Michigan, USA) experienced record-breaking rainfall accompanied by unusually cool temperatures, affording an opportunity to explore how an alternate potential climate scenario may affect phytoplankton. We conducted biweekly sampling of environmental variables and phytoplankton in Muskegon Lake, a Great Lakes Area of Concern that connects to Lake Michigan. We compared environmental variables in 2019 to the previous eight years using long-term data from the Muskegon Lake Observatory buoy, and annual monitoring excursions provided historical phytoplankton data. Under cold and wet conditions, diatoms were the single dominant division throughout the entire growth season – an unprecedented scenario in Muskegon Lake. In 10 of the 13 biweekly sampling days in 2019, diatoms comprised over 75% of the phytoplankton community in the lake by count, indicating that the spring diatom bloom persisted through the fall. Additionally, phytoplankton seasonal succession and abundance patterns typically seen in this lake were absent. In a world experiencing reduced predictability, increased variability, and regional climate anomalies, studying periods of extreme weather events may offer insight into how natural systems will be affected and respond under future climate scenarios.

Water scarcity is a current problem in many parts of the planet and there is a worldwide concern about water availability to meet future water demand. In countries like Brazil, where most of the electricity is produced by hydroelectric power plants, water scarcity directly impacts energy production. The water–energy nexus is directly related and impacted by CO2 emissions and its climate consequences, which calls to a broader approach: energy–carbon–water nexus. In this context, the Sustainable Water and Energy Consumption (SWEC) Program was developed to mitigate water and energy supply problems in a railway company in Brazil. The actions took place in four main areas: (a) users conscientization, (b) consumption diagnosis, (c) indicators for evaluating water and energy consumption, and (d) evaluation of implementing alternative cleaner water and energy sources. The per capita consumption of water and energy were reduced by 10% and 19%, respectively. Permanent results were achieved by the SWEC Program, such as the acquisition of two photovoltaic systems with a total capacity of 96.5 kWp. The investment made provided an average monthly reduction in energy consumption of 56% in 2022. This work contributed to the UN Agenda 2030 and the findings may help companies and industries, and other institutions, such as universities and schools, to improve their water and electricity consumption.

Population growth and economic development, aggravated by climate change, will increase pressure on energy and water resources. Integrated planning can make the most of these two essential and scarce resources. Thirsty Energy, a World Bank initiative, helps countries address these issues and ensure sustainable development of both resources. This note focuses on the water needs of the power sector and particularly answers the following questions: Why is this issue important? Do power plants need all that much water? What about other types of plants? What are the challenges? and, What are our options?

Now and in the future we will consider more and more ecological aspects. The car industry already has a strong commitment to environmental care, but I have decided to investigate how we can go a step further. Imagine a car taking advantage of new and upcoming technologies to reduce its footprint. This vehicle will demonstrate a new method to mass produce cars by simplifying the workflow and reduce the amount of component. The main idea is to be energy efficient while you build it and drive it.

- Source of electrical energy is currently the main problems in Singkawang city, this is because the number of population density increased annually. Besides, the problem of the amount of waste continues to rise, these two problems can be solved with one solution to convert a renewable energy that makes a potential where trash converted into power plant of waste to energy. To determine whether the waste can be a solution to the energy crisis by conducting a study of potential waste or garbage into fuel power plant. writing this essay described how rubbish can produce electrical energy for 24833.76 kWh / day if operating for one year amounted to 9,064,322.4 kWh / year or 9064.32 MWh / year, The first step is to know the total amount of organic waste per day, the number of calories in the organic waste, the amount of energy (kWh) / day, the capacity of power generation, the power output of the boiler, steam turbine net power.
