The coal industry uses the term "clean coal" to describe technologies designed to enhance both the efficiency and the environmental acceptability of coal extraction, preparation and use, [43] but has provided no specific quantitative limits on any emissions, particularly carbon dioxide.
Most coal is used as fuel. 27.6% of world energy was supplied by coal in 2017 and Asia used almost three-quarters of it. [79] Other large-scale applications also exist. The energy density of coal is roughly 24 megajoules per kilogram [ 80 ] (approximately 6.7 kilowatt-hours per kg).
With the development of the steam engine in the United Kingdom in 1769, coal came into more common use, the combustion of which releases chemical energy that can be used to turn water into steam. [5] Coal was later used to drive ships and locomotives. By the 19th century, gas extracted from coal was being used for street lighting in London. In ...
An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
Energy resources may be used in various different ways, depending on the specific resource (e.g. coal), and intended end use (industrial, residential, etc.). Energy production and consumption play a significant role in the global economy. It is needed in industry and global transportation.
Cambodia's domestic energy supply in 2021 was 9,255 GWh, with 44% hydro, 41% coal, 8% fuel oil, and 6% solar. [5] Many rural communities are making use of solar power to access electricity. Cambodia had 305 MW of solar installed at the end of 2021, with seven grid-connected projects. Another 700 MW was planned or under construction. [5]

In this context, it is essential for education to adopt a humanistic approach, particularly in light of the increasing prominence of digital technologies. [7] An example of the application of innovative technology in education is the implementation of an AI-based tutoring system at an entry-level IT school in Pensacola by the U.S. Navy.
