Green technology is also used as sustainable or environmental technology. It takes into account the long and short-term impact of something on the environment. Green technologies are environmentally friendly by definition. It includes energy efficiency, recycling, health and safety concerns, renewable resources and more.

Harmful energy policies, excessive use of resources, scarcity of water resources, global climate change and deforestation are just a few of the issues that experts say people need to address in order to achieve sustainable life on this planet. By 2025, 2.9 billion more people will be forced to access water resources, and according to the United Nations, the world's energy needs will increase by 60 percent in 2030. LiveScience refers to 10 technologies that can help make the future a little brighter, some new, some new and some extraordinary.

• Getting Fat from Everything: All kinds of carbon-based waste, from turkeys to used tires, can be converted into oil by adding enough heat and pressure to a process called thermo-depolymerization.
• Obtaining Salt From Sea Water: Removal of salt and minerals from sea water, desalination is a way to provide drinking water in some parts of the world where resources are limited.
• Green Technology Effect with the Power of Hydrogen: The use of hydrogen fuel cells is promoted as a pollution-free energy source (Hydrogen Energy) as an alternative to using fossil fuels.
• New Ideas about Solar Energy and Green Technology Move: The energy of the Sun that hits the Earth in the form of photons can be converted into electricity or heat.
• Heat Energy Conversion from the Oceans: The largest solar collector in the world is our ocean mass. The oceans absorb heat from the sun, equaling the thermal energy contained in 250 billion barrels of oil from the sun.
• Green Technology Transformation with Tides: Oceans cover more than 70 percent of the Earth's surface. The waves contain a lot of energy that can be directed to turbines that can convert this mechanical power into electricity
• Growing Plants on Roofs: Roof gardens help reduce the carbon dioxide effect by absorbing heat, taking CO2 and giving oxygen, absorbing rainwater and reducing the use of air conditioning in the summer.
• Allowing Plants and Microbes to Clean: It involves cleaning nitrates with the help of microbes in contaminated water and using plants to remove arsenic from contaminated soil (such as Arabidopsis in the picture above) in a process known as phyto-regulation.
• Embedding Harmful Gases: After CO2 is separated from other emission gases, it can be buried in abandoned oil wells, salt water reserves and rocks.
• Producing Ageless Paper: A paper that can be designed from electronic paper, which is a flexible screen that is very similar to real paper but can be used repeatedly.
