''Sustainable Development Worldwide'' : eco-construction, green energy and renewable for all.

Explain your idea in details:

Affected by the pollution caused by cement and by the lack of energy, my idea is to build ecological houses and build autonomous electricity production systems, such as Micro dams, solar systems, wind turbines, ... Who let everyone have light. Note that, With 50% cement per m3 of concrete, the latter is one of the least ecological materials in its manufacture. According to the latest figures, the cement industry alone is responsible for nearly 5% of the planet's annual CO2 emissions. it is possible to define an ecological building as being a house with the objective of respecting the environment. To do this, it will be studied to reduce its environmental impact in terms of pollution and energy consumption. This general definition makes it possible to determine the contours of the concept of green building. These ecological houses make it possible to reduce its environmental impact, but also to preserve the health of its inhabitants. Beyond these qualities, we will offer electricity wherever sources are available. Note that the lack of electricity often leads to the slowdown of daily economic activity and has an impact on the daily life of residents. It has become essential to everyday life and constitutes an essential component to the development of the world. The energy deficit constitutes the major cause justifying the underdevelopment of Africa. That is why, the ambition to become an emerging country in a relatively short time necessarily passes by the development of energy resources very varied and widespread on its territory. The world's electricity needs and particularly those of Africa are continuing to increase. It is therefore imperative to solve this problem by proposing viable and less expensive solutions, therefore ecological houses and electricity for all, and wherever sources are available and above all, renewable.

Expected impact of your idea on sustainable development

know that to be recognized as ecological, these materials must meet several criteria: -They must be from a renewable source. -Their production must have a low impact on the environment, it must not generate greenhouse gases. -They must be materials that are safe for the workers who handle them. -These are materials that must not be toxic to the ecosystem and to living things. -They must limit the costs associated with transport and should therefore ideally come from a local sector. -Their installation must not generate additional energy production. -Their lifespan must be long enough not to require frequent renewal. -These materials must be recyclable. -They must improve the quality of life of the occupants of the house, by producing shade, light, improving indoor temperature, air quality, etc. The houses we build will have a great positive impact on the environment and the health of populations. Likewise, with our systems to produce electricity everywhere in order to decentralize the transport and distribution of the latter, the populations, even remote villages will be able to have electricity using their local natural and renewable resources, this will ensure the development and well-being of all.

Plans for implementation and sustainability

This concept is generally the concept that makes entrepreneurship, business, creativity, development, well-being, innovation, pollution reduction and human health protection interact. Being a fusion between modern construction and ecological construction, in Africa and all over the world, we aim, with other partners, to offer the best price-quality ratio of construction to all. Our objectives are to develop the world with the most advantageous constructions for the environment and we want to offer energy to everyone with local and decentralized micro-power plants. We aim to offer our services to all Africans and all over the world, even states and multinationals. We will form a team with engineers and experts from several fields in order to meet the expectations and requirements of everyone in order to contribute to the well-being of all .This action will strengthen cooperation between countries and continents.

Your profile

My name is NANA Elsa, I was born on May 12, 1999. I am a civil engineering student at the end of my training at the National Polytechnic School of Douala. I am passionate about everything that affects construction in general and sustainable development in particular. I am very hardworking, dynamic, rigorous I am also interested in the field of water and energy and also in the activities of blessing. For me, everyone has a right to happiness, this in a holy, green, renewable and diverse environment despite the differences of social class, gender and state of health. This is why the objectives of sustainable development have long since become my personal objectives. I participated in the "2016 technovation program" technology innovation competition and I and my team took the 3rd prize. subsequently I did several internships in the field of civil genie.

What's the point of being alive if you don't at least try to do something great? You only live once, if you live it right, once is enough.

I really support your idea completely.. your idea is unconventional.
never give up

Always remember, you have the strength, patience and passion to reach for the stars to change the world.
Your idea is great.
There is only one thing that makes a dream impossible to achieve: the fear of failure.

Every great dream begins with a dreamer. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world. Success is not final, failure is not fatal, It is the courage to continue that counts.

Your idea is very smart and practical.

Nice idea Elsa , very innovative good to see the youth working for a change but I would mention how you would find people willing to buy the house and how you will start with limited funds as real estate is a capital intensive business

Hi Nana Elsa. This is a great idea. If I were you I would add more information on how are you planning to activate demand for this new concepts of construction. Sometime people resist to change and it is important to strategize how we can influence them to change. Good luck and wish you success!

Good Idea Mr. Elsa keep it up, energy is one of the major problem specifically in African country coming up with this new solution could be of great importance. We as young we have to find a way to make the world suitable to every one. Wishing you all the best.

I am the contestant too but I am focused on Agriculture Improvement if you dont mind you can vist my Idea and leave your comments at

Great idea Elsa! I'm a Professional Civil Engineer and it's great to see that as a student you are already thinking of how to contribute greatly to the build environment. Kindly research more and highlight what material particularly you would want to replace a portion of cement with. Remember the material should not just be ecological but economical too. All the best.

thank you very much for the support Tommy Zheng. I am of the same opinion as yours, Bamboo is a very good ecological material that we must promote. we are in an area where, because of the consequences due to pollution, we really have to lean towards eco-construction and sustainable development. thankyou very much for your comment.

Merci beaucoup NANGA pour ce commentaire. Merci pour le soutien. Oui ce projet est \'un des projets auxquels je tiens vraiment. Développer le monde tout en protégeant la nature, en évitant de polluer l\'environnement et en protégeant la santé des personnes. Eco-contruction et énergie renouvelable, c\'est ce qu\'il faut pour le futur.

Très belle initiative, un projet qui résoudra de nombreux problèmes. Préserver notre environnement tout en participant au bien des populations. Je vote pour!!!

Great job! This definitely is a huge problem that needs a solution. I did a little bit of research and found that bamboo is actually one of the most eco friendly material to use for environmentally friendly construction, so maybe you can look into that to strengthen your idea. Good luck!
