The term is also used to describe sustainable energy generation technologies such as photovoltaics, wind turbines, etc. Sustainable development is the core of environmental technologies. The term environmental technologies is also used to describe a class of electronic devices that can promote sustainable management of resources.
Water purification: The whole idea/concept of having dirt/germ/pollution free water flowing throughout the environment. Many other phenomena 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.[1]
Air purificationEdit
Air purification: Basic and common green plants can be grown indoors to keep the air fresh because all plants remove CO2 and convert it into oxygen. The best examples are: Dypsis lutescens, Sansevieria trifasciata, and Epipremnum aureum.[2] Besides using the plants themselves, some species of bacteria can also be added to the leaves of these plants to help remove toxic gases, such as toluene.[3][4]
Sewage treatmentEdit
Sewage treatment is conceptually similar to water purification. Sewage treatments are very important as they purify water per levels of pollution. The most polluted water is not used for anything, and 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.[5]
Environmental remediationEdit
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 methods.[6]
Solid waste managementEdit
Solid waste management is the purification, consumption, reuse, disposal and treatment of solid waste that is undertaken by the government or the ruling bodies of a city/town.[7]
Sustainable energyEdit

Concerns over pollution and greenhouse gases have spurred the search for sustainable alternatives to our current fuel use. The global reduction of greenhouse gases requires the adoption of energy conservation as well as sustainable generation. That environmental harm reduction involves global changes such as:
reducing air pollution and methane from biomass
virtually eliminating fossil fuels for vehicles, heat, and electricity, left in the ground.
widespread use of public transport, battery and fuel cell vehicles
more wind/solar/water generated electricity
reducing peak demands with carbon taxes and time of use pricing.
Since fuel used by industry and transportation account for the majority of world demand, by investing in conservation and efficiency (using less fuel), pollution and greenhouse gases from these two sectors can be reduced around the globe. Advanced energy efficient electric motor (and electric generator) technology that are cost effective to encourage their application, such as variable speed generators and efficient energy use, can reduce the amount of carbon dioxide (CO2) and sulfur dioxide (SO2) that would otherwise be introduced to the atmosphere, if electricity were 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.[8][9][10][11][12] Some scholars have expressed concern that the implementation of new environmental technologies in highly-developed national economies may cause economic and social disruption in less-developed economies.[13]
ExamplesEdit
The Tesla Roadster (2008) was the first all-electric sports car for sale and in serial production. It can completely recharge from the electrical grid in 4 to 48 hours depending on the outlet used.
Renewable energy is the energy that can be replenished easily. For years we have been using sources such as wood, sun, water, etc. for means for producing energy. Energy that can be produced by natural objects like the sun, wind, etc. is considered to be renewable. Technologies that have been in usage include wind power, hydropower, solar energy, geothermal energy, and biomass/bioenergy.
Energy conservationEdit
Energy conservation is the utilization of devices that require smaller amounts of energy in order to reduce the consumption of electricity. Reducing the use of electricity causes less fossil fuels to be burned to provide that electricity.
eGain forecastingEdit
Egain forecasting is a method using forecasting technology to predict the future weather's impact on a building.[14] By adjusting the heat based on the weather forecast, the system eliminates redundant use of heat, thus reducing the energy consumption and the emission of greenhouse gases.[15]
EducationEdit
Courses aimed at developing graduates with some specific skills in environmental systems or environmental technology are becoming more common and fall into three broads classes:
Environmental Engineering or Environmental Systems courses oriented towards a civil engineering approach in which structures and the landscape are constructed to blend with or protect the environment;
Environmental chemistry, sustainable chemistry or environmental chemical engineering courses oriented towards understanding the effects (good and bad) of chemicals in the environment. Such awards can focus on mining processes, pollutants and commonly also cover biochemical processes;
Environmental technology courses oriented towards producing electronic, electrical or electrotechnology graduates capable of developing devices and artefacts able to monitor, measure, model and control environmental impact, including monitoring and managing energy generation from renewable sources, and developing novel energy generation technologies.
