Essays on Geothermal Energy

The development of human society is inextricably linked to the use of our planet's natural resources, with the consumption of various types of energy in ever-increasing scale. All the achievements of modern civilization - a huge variety of goods, different in speed and comfort, transportation, space travel, etc., are possible thanks to the huge amount of artificial energy, which produces humanity. The basis for the production of thermal and electric energy is the process of burning fossil fuels -coal, oil, gas. The scale of the production and consumption of fossil fuels, metals, water, air for the production of essential ...

Introduction

The concept of sustainable development was first introduced in 1987 by the United Nations as part of the Report of the World Commission on Environment and Development, in which it was stated that sustainable development implies “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (United Nations General Assembly, 1987). The World Conservation Strategy published in 1980 served as prelude to the conception of this notion, as the UN recognized the importance of minimizing the impact of human activity over the earth’s ecosystems and adopting models inclined towards sustainability ...

It used to be so easy. For tens of thousands of years, humans used wood-burning fire to heat their dwellings, to cook their food, to forge simple tools. Tens of thousands of years before that, human’s ancestors harnessed the power of fire, giving them a hunting advantage over other animals. Then, the population started to increase, especially after the Plague had ravaged much of the world’s population. Wood became scarce, especially in places of dense population, such as England. The increasing rarity of the resource made the demand for another source of energy greater than the demand ...

Introduction

Geothermal energy refers to natural heat stored underground beneath the earth’s crust. On the ground surface the energy is evident in form of hot and altered ground, hot springs and fumaroles. The energy is tapped by sinking geothermal wells underground. The high temperature and pressure fluid is extracted and through carefully built wells and designed network of pipes and channels the hot steam to the plant turbine to generate electricity. The steam and water are extracted at very high pressure and temperature. The application of geothermal energy has gained popularity globally because of its environmental friendliness. There are ...
