    Environmental technology or envirotech, also called green technology or clean technology, applies theories from environmental science, green chemistry, environmental monitoring and energy conservation to provide better ways for humans to interact with the world. Green technology is apart of sustainable development. Recycling, water purification, air purification, sewage treatment, environmental remediation, solid waste management, renewable energy and energy conservation are all included in green technology. New technology becomes available every year that challenges the old world thinking of how to use resources.

    Biofiltration is one pollution control technique that uses living materials to capture and biologically degrade process pollutants, such as those in waste water. This technology helps to remove both air and water pollution. In most applications, biofiltration treats malodoros compounds and water-soluble volatile organic compounds often found in food and animal products.

    Electricity by hydropower is another example of green technology, where electrical power is created through the use of gravitational force of falling or flowing water. Hydroelectricity is used as a renewable form of energy in many societies. This technology produces hardly any direct waste and produces a lower level of greenhouse gas carbon dioxide. 

    Solar power is one of the most recognized green technologies. Using sunlight, solar panels convert the light into electricity, either by photovoltaics or concentrated solar power. Concentrated solar power use lenses or mirrors to focus large portions of sunlight into a small beam. Photovoltaics convert light into electric currents using what is known as the photoelectric effect. Solar power is becoming more common and even comes with tax benefits for those who install solar panels in homes and businesses.

    There are new forms of energy conservation technology being developed every year. Engineers work exclusively on projects to create different energy conservation applications, such as electronic ballasts for high-intensity gas discharge lamps for use along public roads. Other gadgets include solar powered clocks and new energy efficient washing machines are also a focus in the green technology sector.
