Sustainable development is essential for our future and our host, our Earth, needs it desperately. All of the eight UN Millennium Development Goals rely directly or indirectly to the availability of sustainable energy. Sustainable energy means not only that the energy conversion technology be safe, secure, clean, minimal resource intensive and cost-competitive but also that a maximum of the energy converted can be used in non-energy applications as agriculture, transport, health care, economic development, education and many other activities.

The global annual energy flow as today cannot be sustained during this century and beyond. Internalising all the external costs associated with energy conversion, especially relating to health and environmental impact, will be discrediting especially the fossil-fueled energy conversion technologies. 

The future of the energy system is nowadays mostly debated in the context of climate change and thus the abatement of GHG-emissions. Though, a sustainability evaluation of our energy balance requires a truly systems view encompassing more than only the GHG-emissions dimension. Sustainable development for the world requires willingness to revisit, develop and deploy innovation in urbanisation, transport, labour organisation, water management, supply chains, agriculture and in the overall ecosystem as a whole.

The growing electrification during the 20th century is set to accelerate during this century. Even today, about 1,3 billion people lack household electricity directly and indirectly impacting family's comfort, security, health, education and overall well-being. Electrification helped to improve overall efficiency in industry, in the residential sector and services sector (some 6% of today's electricity being used to the IT-infrastructure worldwide) and is set to become a game-changer in the transport sector during the coming decades. 

"Let's Energise Sustainability" is the title of our book to be published during Q2/2016 by mapping out the system scenarios towards sustainable futures 'fueled' by sustainable energy. Part of our ongoing analysis will be already provided though this website and open for discussion.

Nuclear energy is today among the most sustainable energy conversion technologies and is considered by many countries and investors as a relevant option for today's and tomorrow's sustainable energy mix.

Any use of nuclear energy has to comply with four objectives to cope with the technical-economic and the socio-political values to be ensured for sustainable energy systems:

  1. Safe and Secure development and operation;
  2. Cleanliness by minimising overall resource-use, waste-arising and stewardship longeivity;
  3. Reliable through performing design, engineering and operation and application;
  4. Affordable by matching the market conditions.

Today's nuclear energy use was mostly developed in western countries though currently experiencing a stagnated and essentially replacement market within these countries while the main deployment potential occurs today in Asia and soon in other world regions. Today's nuclear energy use worldwide and anticipated use for the foreseeable future is visualized below based on our databases and available for download and consultation using the Tableau-application.

After more than 50 years of R&D and industrialisation of nuclear energy, multiple options are available to further the sustainability of nuclear energy. Nuclear energy scenarios assessments are undertaken by many where we're among the referenced nuclear energy scenario contributors mainly based on the use of DANESS as our main modeling tool to assess nuclear energy system scenarios.

Nuclear Energy Scenarios

Many scenarios for nuclear energy use are envisageable though the main intra-nuclear scenarios are sketched in the following figure. 

An indicative timeline shows the envisageable introduction dates, on world-level, of certain nuclear reactor technologies and the main material flows for the uranium and plutonium as well as thorium in those scenarios. All of these scenarios are detailed in our specific web-section on nuclear energy system scenarios as an international referenced discussion forum on nuclear energy scenarios.
