The dominant form of particulate matter from coal-fired plants is coal fly ash, but secondary sulfate and nitrate also comprise a major portion of the particulate matter from coal-fired plants. [26] Coal fly ash is what remains after the coal has been combusted, so it consists of the incombustible materials that are found in the coal.
Science, technology, society and environment (STSE) education, originates from the science technology and society (STS) movement in science education. This is an outlook on science education that emphasizes the teaching of scientific and technological developments in their cultural, economic, social and political contexts.
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).
Carbon taxes can motivate consumption to shift to energy sources with fewer emissions of carbon dioxide, such as solar power, wind power, hydroelectricity or nuclear power while avoiding cars with combustion engines, jet fuel, oil, fossil gas and coal. On the other hand, taxes on all energy consumption can reduce energy use across the board ...
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.
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.
Technology education is an offshoot of the Industrial Arts tradition in the United States and the Craft teaching or vocational education in other countries. [4] In 1980, through what was called the "Futuring Project", the name of "industrial arts education" was changed to be "technology education" in New York State; the goal of this movement was to increase students' technological literacy.

The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.
