Energy Resources
Energy resources refer to the various natural sources of power that can be harnessed to produce energy. These resources include fossil fuels such as coal, oil, and natural gas, as well as renewable sources like wind, solar, hydroelectric, and geothermal energy. The use and management of energy resources have significant environmental, economic, and geopolitical implications.

In physics, energy is defined as the capacity to do work, which is measured as the potential energy or the kinetic energy. Contrarily, in economics, energy is regarded as fuel (Martinás, 2005). Energy is valuable only when it is effortlessly convertible to useful work, andfossil fuels account for most of the world’s convertible energy, thereby playing an important part in affecting human civilization. Sun is the primary source of energy on earth providing all living things, including our bodies, the capability to live, grow, repair tissue, reproduce, and do work. As it does so, energy changes from one form to another, i.e., from electromagnetic radiation flowing through space to chemical energy stored in plants, to heat that keeps us warm, to potential energy as we climb a mountain, and to kinetic energy as we move back down again. In order to heat our houses, produce our electricity, and drive our vehicles,we usesolarenergy that plants gathered and stored long ago. It is continuously converted from one form to another as the energy works its way through nature and human societies...

...Economic activities take place in particular localities for a reason. One of these reasons is access to resources. Just from looking at a map or thinking about geography, it is apparent that the resource endowment, or resource repertoire, varies across different locations. Different regions offer very different resources. Some locations have an abundance of certain resources while they are completely absent elsewhere. In the earliest eras of economic geography that focused around empirical description, mapping the presence of resources in different places was a key disciplinary objective. However, looking more closely and more conceptually at this issue, one finds that resources link to space to different extents. Some resources are completely bound to a place and cannot be easily moved whereas others can. A few resources are found almost everywhere: there is no particular source. Traditional Weberian location theory developed a couple of useful stylized concepts around this (Weber 1909). It says that inputs (resources) are either localized (accessible at a given point on the map) or ubiquitous (accessible everywhere at the same cost). The fact that a resource is “localized” does not mean that it is unique to one specific place. It could actually be available from several different sites. A good example is iron ore. It is a localized resource, but there is not just one mine on earth. In reality, most resources are localized to some extent (accessible at a given point on the map), but many of them, like iron ore, can also be moved or transported to other regions, although this incurs a cost. A localized resource has a source, and there is a cost to moving it or accessing it from distant locations. Iron ore has therefore one key characteristic that it shares with other localized resources: the cost of accessing it can be assumed to vary across space. In this sense, we can think of space – geographical distance – as a friction that limits access to localized resources...

...The European Union ranks first in biomass power generation in terms of scale. Geothermal energy is a general term for thermal energies in the Earth’s crust. It is categorized mainly into categories such as hot water type, steam type, ground pressure type, hot dry rock type, and lava type. It is estimated that the workable reserves of global geothermal energy is equivalent to 5 billion tons of standard coal, mainly distributed in the Pacific Rim geothermal belt, the Mediterranean–Himalaya geothermal belt, the Atlantic midocean ridge geothermal belt, and the Red Sea–Aden–East African Rift Valley geothermal belt. Heat utilization and geothermal power generation are two major means of utilizing geothermal energy. As at the end of 2013, the installed capacity of global geothermal power generation reached approximately 11.71 GW. 1.4. Energy Development in the Arctic and Equatorial Regions In terms of the distribution of world clean Energy Resources, the Arctic Circle and its surrounding areas (the Arctic region 12) are found to have rich wind Energy Resources, while solar Energy Resources are also abundant at the Equator and its vicinity (the equatorial region 13). Centralized development of wind resource in the Arctic and solar resources at the Equator will be an important direction of development for world resources. Resources will be delivered to load centers across the continents via ultra-high voltage and other electric power transmission techniques in mutual support for large energy bases and distributed generation to ensure a safer and more reliable supply of clean energy. 1.4.1. Energy Development in “The Arctic Region” 1.4.1.1. Overview of Resources Wind Energy Resources are rich and widely distributed in the Arctic region, with a technologically developable capacity of 100 TW or 20% of global onshore wind resources. Wind resources are most abundant in the Kara Sea, the Barents Sea, the Bering Strait, and Greenland along the Arctic Ocean...

...6 Resources Introduction When armed with a vision of what geography is about (as discussed in Chapter 1), the nature and quality of the ‘resources’ (materials) that we use in the classroom are of fundamental importance. Geography classrooms are usually, and understandably, ‘resource rich’ – full of imagery of all kinds including maps, all designed to bring the subject alive in the classroom. As David Rayner (2017: 150) describes in the Geographical Association’s Handbook for Secondary Geography, teachers have never had so much choice of materials in our digital age. However, this can be a double-edged sword; resource rich classrooms are not always conducive to effective, worthwhile geographical learning! Resources are not ends in themselves – they need to be selected and used with care and serve the purposes of the curriculum. There should be a very close relationship between the planning processes described in Chapters 2 and 3, and the selection and preparation of resources. When selecting resources or preparing new resource materials of your own, you should have a clear idea of their purpose. In other words, the resources needed are determined by: the geography you want pupils to learn; the teaching strategies and learning activities you planned to use; the curriculum goals that these serve. On the other hand, it is occasionally true that the discovery of a particular resource may itself provide the source of inspiration for a lesson or sequence of lessons (see Chapter 2 for discussion on especially significant resources called ‘curriculum artefacts’)...
