This presentation gives the result of the emerging issues analysis of the SESTI project on the energy domain in 2010. It provides the questions around 5 of the less well known future sustainable options/risks that were discussed in the project. The topics that were addressed are still worth while to review today.
These topics were :
1. Enhancement of the photosynthetic cycle on global scale to provide all food, energy and maintain biodiversity (briefly biomimics)
2. Use of desert areas for gaining solar energy (the DESERTEC scheme)
3. Hybrid nuclear fission-fusion to speed up nuclear fusion
4. The unknown risks of going deeper and further for energy mining
5. The unknown risks of and hydrogen leaking economy

15. Figure ES.1 North American carbon sources and sinks (million tons of carbon per year) in 2003. Height of a bar indicates a best estimate for net carbon exchange between the atmosphere and the indicated element of the North American carbon budget. Sources add CO2 to the atmosphere; sinks remove it. Error bars indicate the uncertainty in that estimate, and define the range of values that include the actual value with 95% certainty. See Chapter 3 and Chapters 6-15 of this report for details and discussion of these sources and sinks .

Solar cell (and furnace) parks in desert areas like the Sahara could provide the electricity for the whole world , even if they would cover only a small part of the desert Desertec is about 2500 Km2 supplying the whole sahar region of electricity needed also to develop agriculture of the rest of the desert Further to supply Europe
