An energy flow chart or "atlas" for 136 countries has been constructed from data maintained by the International Energy Agency (IEA) and estimates of energy use patterns for the year 2007. Approximately 490 exajoules (460 quadrillion BTU) of primary energy are used in aggregate by these countries each year. While the basic structure of the energy system is consistent from country to country, patterns of resource use and consumption vary. Energy can be visualized as it flows from resources (i.e. coal, petroleum, natural gas) through transformations such as electricity generation to end uses (i.e. residential, commercial, industrial, transportation). These flow patterns are visualized in this atlas of 136 country-level energy flow charts.
Suburban neighbourhoods pose challenges to decarbonisation, due to high car-dependency and relatively large and energy inefficient homes. Home ownership dominates suburbia, thus putting responsibility on households to adopt measures to decarbonise their domestic lives and transportation. This paper examines household perspectives on the feasibility of such measures. We ran a survey and focus groups in Perth (Scotland) during the energy crisis. Whilst we found high levels of concern about climate change, energy costs, and growing engagement with cleaner technologies (e.g. heat pumps), most residents felt decarbonisation options were limited. Barriers like technologies’ up-front costs, worsened with the cost of living crisis. Participants had low familiarity with sharing economy approaches like car clubs. Despite high (non-electric) bike ownership and prevalence of storage space (garages), cycling was more perceived as a leisure activity than a regular transport mode. There were shared views that the state should take a stronger role in coordinating and implementing systemic changes required for energy transition, including measures affecting residents directly, like reducing car traffic into the city centre. We conclude that despite the economic privilege of high home and car ownership in suburbia, few felt financially able to decarbonise and most seem locked into high-carbon suburban lifestyles.
Approximately 11,000 trillion British Thermal Units (trBTUs) of electricity and fuels were used throughout the United States residential sector in lighting, electronics, air conditioning, space heating, water heating, washing appliances, cooking appliances, refrigerators, and other appliances. The residential sector is powered mainly by electricity and natural gas. Other fuels used include petroleum products (fuel oil, liquefied petroleum gas and kerosene), biomass (wood), and on-premises solar, wind, and geothermal energy. The flow patterns represent a comprehensive systems view of energy used within the residential sector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
