Hi Sivasubramanian,
I agree that the energy topic is a very critical one as Mike was
mentioning, and it is important for researchers to be working on it.
I know that Engineering for change has a course on renewable that is
good: 
https://www.youtube.com/watch?v=n0nMC_laVvI (and more info like
this in our monthly newsletter here 
http://gg.gg/locnet-newsletter)
If there are innovations in energy generation and provision that would
be great to get out, test and share (and I want to help on that, so
please share !).
Sustainability is a multidimentional problem where enery is one of those
dimentions, among governance, finantial, usage, expansion.
Also, my cautious self would say that we need to facilitate technologies
so Communities can have as many options as possible, that we need to
listen their needs and work for them in order to find solutions that are
suitable to their needs, and try the most we can not to have a
technocratic view at the matter.
I feel that in order to co-design we need spaces were the communities
and the technicians sit down together to hear each other.

 Dear Michael,
 
 There is ample potential to BUILD IN sustainability as Community
 Networks are relatively (and considerably) new, and we could design
 anew, as from a blank sheet of paper if necessary. If 99% of the energy
 is consumed by the infrastructure, we could think of design innovations
 such as inland cable landing stations and low power Point to Point
 towers and wifi routers. 
 
 ( Aside from the power issues, there is the issue of radiation from
 towers and mobile phones which for some reason or other, does not get
 attention )

     Hi Siva,
 
     Something I argued in the 2017 DC3 report is that CNs, by their
     nature, have to consider energy and other elements of sustainability
     within the design of the network. Energy, however, is but one of the
     factors involved in sustainability. I'd love to hear from others who
     actually deploy networks, though, to hear what you think.
 
     Best,
     -Michael

         The so called 5G would take the mobile phone technology further
         high above as a disproportionately high-energy technology.  The
         Stanford article seems to focus on "prioritizing and
         constructing high-energy systems", NOT on sustainable
         technologies and NOT on addressing the social costs of the
         high-energy mobile phone technology. Is there any research done
         on the comparable energy requirements of Community Based
         Networks? As we are relatively in the early phases of deploying
         Community Networks, there is potential to build energy
         sustainability in the design of large scale community networks.

             Hi everyone,
 
             I want to share this article
             <https://ssir.org/articles/entry/scaling_power_for_global_prosperity#>
             with you all about ending energy poverty and what is needed
             to address electrification. I particularly liked this
             paragraph (emphasis mine):
 
             /"The mobile phone revolution is often cited as an example
             that can be replicated for energy. But mobile communications
             technology actually exemplifies the need for high-energy
             systems. Charging phone batteries accounts for less than 1
             percent of the energy required for a smartphone to operate.
             The other 99 percent is needed by the wider economy to
             manufacture the phone, and to run the cell towers and data
             centers that enable the phone to function. *The mobile phone
             is a high-energy technology masquerading as a low-energy one*."/
 
             Best,
             -Michael
