Necessities of self-sufficient skyscraper are realized due to increasing demand of energy as well as shelter for each individual of such a huge population. The word ‘self-sufficient’ for a building or a tower explains that it is a building designed to be worked independently by harvesting all its energy requirements using onsite renewable energy generators and lessening the burden over other power sources. The main significant feature of self-sufficient towers is to minimize different problems related to global warming and environmental pollution and to design a sustainable architecture that would not be dependent on conventional energy sources and can become an independent point source of energy production for its own use. Here is a list of 10 such planned self-sufficient towers:

1. Farm Tower in London

The concept of farm tower was proposed by Dickson Despommier in the year 2000 in which a project of cultivation of agriculture foodstuffs and livestock in multi-storey building structures, those will be introduced within urban areas, was kept ahead. These buildings will also be the solution of residential problems for the urban population. Such a farm tower was designed to be built in London by Brandon Martella. The building will offer a total area of one million cubic feet for farming purpose, in which the production of a variety of fruits and vegetable can be done. The building will be capable to harvest rain water as well as solar energy for farming whereas large vertical axis turbine will ensure the generation of power by utilizing wind energy.
2. Eco Skyscraper

The concept of Eco Skyscraper was put forward by Vikas Pawar to fulfill the necessities of potable water, food and green energy by a tower to the people of Noida, India. The building would be equipped with enormous solar cells and wind turbines to harvest solar and wind energies. Two spiral shaped towers, connected each other through a bridges, will also make available the place for growing daily vegetables. The rain water is harvested as well as recycled to prevent its loss.
3. The Oasis Tower

The Oasis Tower was designed by Rahul Surin and set to be located at Zabeel Park, Dubai. The idea of Oasis Tower was developed after viewing the shortage in the amount of land available for farming as well as increasing population in Dubai. The tower would make available a solution for urban farming along with sustainable accommodation. The project of Oasis Tower is designed in such a way that it would ensure the availability of food enough to feed approximately 40,000 people every year. The tower system will be capable to generate the electricity requirements by own by harvesting solar and wind energies.
4. Gyre – A self-sufficient underwater tower

Gyre is an underwater skyscraper design that generates required energy by harvesting solar, wind and tidal energy proposed by Zigloo. The construction will be located at a depth of 400 meters with having few hundred meters up water enlargements that will offer a comfortable accommodation and working atmosphere, together with large space for shopping malls, restaurants and recreation.
5. Wind Tower

Fully green ‘Wind Tower’ is another self-sufficient skyscraper to be used as a luxury resort. It contains the solar cells and wind turbine to harvest the natural energy. Swimming pools are multifunctional as these are also utilized as water reservoirs, fire fences and catch basins along with their usual function. Indoor gardens are also available to maintain inside atmosphere clean and cool.
6. Aviapolis Tower

The model of Aviapolis Tower was proposed by K2S architects with a height 70 meters. An energy square, equipped with a series of solar panels and wind generators, has separately been designed to make up the energy demand. The square is located between the main building and highway. Even in its aesthetic point of view, the tower will be a milestone of its specific shape.
7. Tata Tower

Tata tower is an answer to the increasing parking problem in Mumbai, India, which was conceptualized by Seth Ellsworth & Jayoung Kim. It will be a self-sufficient tower with having vertical parking facility for nearly 4,001 cars at a time. Along with parking facility, the building will accommodate 930 employees of Tata Company.
8. Botanical Tower

Botanical Tower is proposed to taking shape beside to the River Lea in U.K. having a concept of vertical farming and gardens. Rainwater harvesting system is sufficient for nearly all the water need. Along with that, it would be able to develop its green energy by large windmills and solar panels.
9. Fibrous Tower

It is also a self-sufficient and sustainable tower designed for minimize the load over traditional electric power grids, which is conceptualized by Kokkugia, a New York based architecture. As name states itself, the tower will be constructed using fibrous framework to increase its durability.
10. BURJ AL-TAQA

Burj Al-Taqa is an enormous type of self-sufficient skyscraper with pure green design and producing 100% of own electricity. The cylindrical shaped building will have 68 storeys covered with sunshields to minimize sunlight exposure resulting into reduced need for air conditioner. Although solar and wind energy will be used to fulfill the energy need, additional requirement is harvested by hydrogen fuel that was produced from seawater.
