= Environmental Technology = Environmental technology or green technology is the development of technologies that are used to conserve or reduce the harm humans are causing on the environment. Environmental technologies are used to generate power with the use of different part of the environment. Examples of these technologies are solar power, wind power and hydroelectricity. Some features within these technologies are solar panels, wind turbines and water turbines.

Energy conservation
Energy conservation is "the prevention of wasteful use of energy, especially to ensure its continuing availability". Energy conservations main goal is to reduce certain aspects in ones daily life to help conserve energy. Examples of energy conservation is turning off the lights when walking out of a room, recycling etc.

Solar Power
Solar power is a popular form of energy that is used globally. Solar energy works with the use of solar panels placed in areas which sun is able to produce thermal energy. Solar panels work by producing energy through "particles of light, to knock electrons free from atoms, generating a flow of electricity". Solar panels then allow electricity to form from sunlight. Solar panels produce direct current (DC) electricity.

Wind Power
Wind power is a renewable energy source produced by wind turbines. Wind turbines are usually the size of 20 story buildings, with blades that are roughly 200 feet long. "The blades of a wind generator turning a shaft at 120 revolutions per minute might be stepped up to 24,000 rpm" with the use of a wind turbine. As the wind blows the blades spin and generate electricity. Large amounts of power is generated with the use of wind turbines and it is a very efficient use of renewable energy.

Hydroelectricity
Hydroelectricity works by tapping into different water systems and producing energy. Water is constantly moving around so in order to produce significant amounts of energy “a turbine… rotates a generator to generate electricity”. Though hydroelectricity is a great source of renewable energy because of the different species that live with in water hydroelectricity has a large effect of biodiversity. “Over 85% of biodiversity hotspots overlap with watersheds, and there are large dams in over 80% of those watersheds”.

Green Syndicalism
"Green syndicalism combines green concerns about ecological harmony with syndicalist concerns about ending the exploitation of workers." Green syndicalism originates from the blockades that stop ecological destruction. This principle is meant to help stop the exploitation of workers by combining these ideas with the ideas of ecology.

Sustainability
Sustainability is "the quality of causing little or no damage to the environment and therefore able to continue for a long time". Sustainability is a more modern concept, the idea of conserving or causing little damage to the environment is not new. The term mainly comes from the idea of meshing together different ideas of sustainable development. Sustainability mainly comes from the idea of bettering the earth for future generations to come. The United Nations created specific goals for sustainability to be reached by 2030 and each of these goals apply to specific countries or specific values throughout the globe ; some of these goals include ending poverty, gender equality, responsible consumption and productions, climate action, peace,justice and strong institutions, etc.

Three pillars of sustainability
Sustainability does not only have to do with the environment it also has to do with economics as well. The three pillars of sustainability have to do with people, the planet and profit for the planet and people. All three of the pillars mainly set goals for future generations.

1.Environmental sustainability

Environmental sustainability has to do with the earth. This means keeping the balance of all of the earth's natural resources in balance. Due to many of earth's ecosystems being damaged, these ecosystems are not able to recover. People who depend on natural ecosystems are mainly affected by damages caused by not sustaining a healthy environment. Helping with environmental sustainability will allow for a healthier environment and help with furthering a better future for newer generations.

2. Economic sustainability

Economic sustainability is "the use of various strategies for employing existing resources optimally so that a responsible and beneficial balance can be achieved over the longer term". Economic sustainability is meant to help balance out the financial aspects of the globe.

3. Social sustainability

Social sustainability are basic human rights and necessitates that are attainable by every human being, who are able to have access to resources to keep their lively hoods healthy and secure. "Social sustainability is about identifying and managing business impacts, both positive and negative, on people". Though social sustainability mainly has to do with people's basic rights, business also play a role in this section. Businesses help contribute to people's basic rights by contributing their resources.

Sustainable design
“The traditional definition of sustainability calls for policies and strategies that meet society's present needs without compromising the ability of future generations to meet their own need”. Sustainability involves a large range of things, including design and manufacturing. Sustainable design is promoted to reduce the negative impacts that are made on the environment. Some concepts that are associated with sustainable design are: to optimize size, conserve water, use environmentally safe products.

Sustainable Engineering
Sustainable engineering is the aspect of using sustainable products when engineering new builds, outdoor spaces, etc. This use of sustainable products is meant to help better the earth's water and air. Engineers today will have to take into account if the products they will be using are sustainable to today's environment. Some questions that can be asked by an engineer are: "Will it be made from recycled materials? How much energy will it use? Will it be able to be recycled at the end of its useful life? Will it have parts that contain toxic metals that must be disposed of?" References
