? What is “green technology” and how will it change the earth in the future
Climate change has awakened humanity's awareness of a planet filled with pollution and carbon dioxide in the atmosphere, and the world is now striving to get rid of these problems, so that our future will be greener.
Science has been employed in the service of the planet and the environment in what is known as green technology. So what is this technology? What is its role in development? How will it change the
? future of the Earth
? What is green technology
Green technology can be clarified as a comprehensive term that refers to how technology and science in general are employed to protect and preserve the environment. Reviving a damaged ecosystem and bringing it back to life; Therefore it can be called clean technology as well.
The birth of green technology
The year 2010 is considered the date of the popularity of the term green technology in a large way, but it has been used since the end of the industrial revolution in conjunction with the concerned manufacturers’ efforts to reduce the negative effects of external factors by relying on changes to the production process, including by-products.
Despite this, the matter remained relatively inactive until the nineties. In 2018, the United Nations issued a report revealing the percentage of global investment in the field of renewable and green energy (environmentally friendly); It invests $200 billion in 2017, while in solar and wind energy projects, $2.9 trillion has been invested since 2004 and many more.
Green technology and its role in sustainable development
The world is quickly adopting green technology technologies, and is relentlessly striving to develop them to be environmentally sustainable, and it has become possible to see many examples of them in our daily lives, which indicates the seriousness of the world in developing these technologies for the great role they play in development.
Among the most famous of these examples:
Wastewater treatment, water purification and recycling to be suitable for drinking or other purposes.
Waste management and recycling.
Converting waste into energy.
Programmable thermostats, in which temperatures are programmed to save energy when no one is at home.
LED lights.
vertical farming.
Convert food waste into compost.
Using ocean waves to generate electricity
green technology future
In addition to the aforementioned green technology applications, other technologies are being developed that are expected to become more widespread in the near future.
environmental repair
Environmental reform is to get rid of all the causes of pollutants to the elements of the environment such as water, air and soil, and the processes vary between chemical, biological and others. It drains and exhausts the environment.
Low carbon green buildings
The world is moving towards constructing buildings that do not emit carbon dioxide throughout their lifespan. They use environmentally friendly materials such as bamboo and hemp in their construction, and produce a small percentage of waste and pollutants. They produce their own energy through solar panels on their roofs, and include sufficient insulation to reduce the need for energy needed for cooling and air conditioning, thus becoming the ideal buildings for a green future.
Photovoltaic cells combined with buildings
It is not possible to talk about green buildings without referring to photovoltaic cells, but it seems that integrating them with building blocks in the facades of buildings or roofs is the future trend. These systems, called Integrated Building Photovoltaic (BIPV) systems, are solar panels that mimic the look and function of traditional roofing materials, in addition to generating electrical energy, thus saving building materials and electricity.
Carbon capture and storage
Removing carbon from the atmosphere is the most important step in eliminating global warming and preventing global warming. And in the world's quest to do so, technologies have already existed to remove carbon from the atmosphere. These technologies include drawing carbon from the atmosphere and capturing it and storing it underground for use in making synthetic fuels.
These technologies are still under development, and are not widely applicable, especially as they are expensive, but scientists are optimistic about them, and it is expected that they will be one of the future green technologies.
Renewable Energy Storage
The world is widely adopting renewable energy technologies, but faces the problem of storing this energy and obtaining it in the absence of its sources, as happens when the sun goes out behind clouds for days, or when the wind stops spinning turbines for weeks. The solution to the problem lies in developing batteries that can store large amounts of energy for a long time and at the lowest possible cost
hydrogen fuel
The transportation sector consumes a large proportion of fossil fuels, producing huge amounts of carbon in the atmosphere. As the world turns to green technologies, it is imperative to replace it with clean and renewable fuels, and the appropriate alternative is hydrogen fuel, as vehicles running on it do not produce any harmful emissions and operate in a more efficient manner. More than 400 million cars are expected to run on hydrogen in 2050.
Recycling
Specialists around the world are looking for ways to recycle the waste on our planet, turning it into anything possible from fuel and fertilizer to clothes, bikes and more.
nuclear fusion reactors
Fusion reactors are so energy-intensive that an entire house can be powered for a day with just a 5-second reaction, and are a future candidate for non-fossil-fueled power generation.
Inside these reactors deuterium and tritium are released into superheated plasma, where they are fusing together in a reaction that produces helium, neutrons, and of course energy. This reaction produces a very large amount of energy from small amounts of reactants, and these reactors are sources that cities can rely on in the future to provide their energy needs.
Artificial intelligence
Artificial intelligence has entered a wide range of fields; This is due to its ability to perform tasks with great accuracy and speed, while reducing the huge amounts of waste that results from it, especially in industrial fields, because it can automate many steps in the production chain, thus it enters the field of green technologies.
bioplastics
Some companies have begun producing plant-based plastics that can be completely biodegradable and have better properties than the currently manufactured plastics, as they are made from sugary plant materials obtained from sugarcane, wheat and corn, as well as non-food crops such as agricultural waste. These materials undergo a series of chemical reactions to obtain the basic substance, which is polyethylene furanoate (PEF); It is a type of plastic called polyester.
sustainable phones
Smartphones have become one of the most resource intensive products on the planet. It emits millions of tons of carbon dioxide into the atmosphere, and includes toxic metals such as lead, mercury, arsenic, cadmium, chlorine and bromine in its manufacture.
In order to make mobile phones environmentally sustainable, the US company Teracube is developing phones made from 25% recycled polycarbonate, and it encourages repair, not replacement, and its frame is made to be biodegradable, and its packaging is made of recycled paper and printed Ink from soybeans.
electric cars
Electric cars are the clearest picture of the future of green technology, as car production companies are racing to manufacture them, and stop producing cars that run on internal combustion engines and consume fossil fuels. These companies are still developing more efficient batteries, but it is believed that wireless technology will provide them with electrical power. All electric vehicles will be fitted with devices capable of receiving power from a distance by transmitting an electromagnetic field from cables installed under the road.
