Encyclopedia

From Wikipedia, the free encyclopedia

Environmental technology (abbreviated as envirotech) or green technology (abbreviated as greentech) or clean technology (abbreviated as cleantech) is the application of the environmental science to conserve the natural environment and resources, and to curb the negative impacts of human involvement. Sustainable development is the core of environmental technologies. When applying sustainable development as a solution for environmental issues, the solutions need to be socially equitable, economically viable, and environmentally sound.

Technologies

Sample Technologies

The technologies include, but are not limited to, the following areas:

Recycling
Is a Worldwide Phenomenon, which is a basic application towards the concept of Green Technology. It shows and encourages people to reuse items that can be reusable. Items like saving Cans of food or drinks, Paper etc have been encouraged by the governing bodies around America and rest of the world, to be recycled so that it can be used in the future for several other purposes. It can thus help protect the environment and cause less waste/pollution.[1]
Water Purification
The whole idea of having dirt/germ/pollution free water flowing throughout the environment. Many other phenomenons’ lead from this concept of Purification of water. Water Pollution is the main enemy of this concept, and various campaigns and activists have been organized around the world to help purify Water. Considering the amount of water usage that is under current consumptions, this Concept is of utter Importance.[2]
Sewage Treatment
Sewage Treatment is a concept that is really close to Water Purification. Sewage Treatments are very important as it purifies water in levels of its pollution. The more the water is polluted, it’s not used for anything, the least polluted water is supplied to places where Water is used affluently. It may lead to various other concepts of environmental protection, sustainability etc.[3]
Environmental remediation
Environmental remediation is the removal of pollutants or contaminants for the general protection of the environment. This is accomplished by various chemical, biological, and bulk movement methods, in conjunction with environmental monitoring. (encyclopedia of medical concepts)[4]
Solid Waste Management
The purification, Consumption, Reuse, Disposal and Treatment of solid waste that is looked after by the government or the ruling bodies of a city/town and its proper care is basically known as Solid Waste management.[5]
Renewable Energy
Energy that can be replenished easily is the easiest way to explain renewable energy. For years we have been using sources like wood, sun, water etc for means for producing energy. Energy that can be produced by natural objects like wood, sun, wind etc is considered to be renewable. (Nrel)[6]

Alternative and clean power

Principles

Scientists continue to search for clean energy alternatives to our current power production methods. Some technologies such as anaerobic digestion produce renewable energy from waste materials. The global reduction of greenhouse gases is dependent on the adoption of energy conservation technologies at industrial level as well as this clean energy generation. That includes using unleaded gasoline, solar energy and alternative fuel vehicles, including plug-in hybrid and hybrid electric vehicles.

Since electric motors consume 60% of all electricity generated[citation needed], advanced energy efficient electric motor (and electric generator) technology that are cost effective to encourage their application, such as the brushless wound-rotor doubly-fed electric machine and energy saving module, can reduce the amount of carbon dioxide (CO2) and sulfur dioxide (SO2) that would otherwise be introduced to the atmosphere, if electricity is generated using fossil fuels. Greasestock is an event held yearly in Yorktown Heights, New York which is one of the largest showcases of environmental technology in the United States.[7][8][9][10][11]

Criticism

Extreme radical environmentalism, exhibited in publications such as Green Anarchy, criticizes the concept of environmental technology. From this viewpoint, technology is seen as a system rather than a specific physical tool. Technology, accordingly, requires the exploitation of the environment through the creation and extraction of resources, and the exploitation of people through labor, specialization and the division of labor. Thus, no “neutral” form of technology; things are always created in a certain context with certain aims and functions. Green technology is rejected as an attempt to reform this exploitative system, merely changing it on the surface to make it seem environmentally friendly, despite continued unsustainable levels of human and natural exploitation.
