can hardly imagine human history without energy.
The earliest humans used wood for energy - and in Egypt in 300 B.C.,
wind-using sailors appeared. Humans rapidly turned from wood to coal
in the 18th century - a period of both high population growth and
expansion of the fossil fuel industry. Dangerous lamps (candles) using
animal oil of kerosene were replaced in the 19th century with Edison's
electric lamp invention. The demand for oil energy skyrocketed in
the 20th century along with the high development of the automobile
industry to the point that after WWⅡ. It was difficult
to control the soaring consumption of oil. Thus, humans imprudently
began the consumption of energies that had been stored on earth for
a long time.
|The answer will probably be renewable energies that are available at any
place - such as inexhaustible sunlight, bio-fuels, wind and geothermal energy.
Other examples include devices such as fuel cells using hydrogen fuels.
Many countries are investing a considerable labor force and financial resources
to solve the energy issue. Korea established the goal to provide more than
20 percent of our total energy needs with modern renewable energies by 2050
and is turning its support policies in that way.
|The Energy Science & Engineering Department of DGIST wants to pursue research
and a practical education system to deal with both human history and energy's
destiny. To realize that global interest, it is working on the improvement
of new renewable energies such as solar energy conversion, bio-fuels, fuel
cells, secondary batteries for a more efficient use, geothermal energy,
and on low-carbon gas energy production.
|The chosen motto, "Beyond Future Energies", tells how much the department
considers the work on future eco-friendly energies with trustworthy students
as its mission.
