SharedSolar: Mobiles and Micro-Grids For More Efficient Energy

It is an unfortunate irony that often the poorest people pay the most for the lowest quality energy. In many areas, the rural poor pay as much as 5 USD per month for kerosene or battery power. SharedSolar is a project that attempts to develop the technology, and business case to connect these populations to better, more traditional energy sources. It does so by leveraging existing mobile networks. 

With SharedSolar, rural poor consumers make payments based on their usage by using a scratch card and adding credit via SMS. The system uses a micro-grid network to connect consumers to power, and each household uses a unique prepaid metering system. A group of up to 20 consumers (individuals, households, small businesses, or schools) are all located within a 50 meter radius of a single, central power source -- such as solar panels -- connected via an underground wire. 

At the same time, the SharedSolar team is testing and developing its business model to show that a case exists for micro-grids and mobile energy payment. The team launched an initial pilot in 2010 in Pelengana, Mali and currently has systems set up in Uganda and Tanzania. 

MobileActive.org spoke with Matt Basinger, project lead for SharedSolar, to learn more about the overlap of mobile technology and rural power.

Safer Facebook

Facebook has more 500 million users, half of which access the site through their mobile phones. Being able to communicate your message to an audience this large is exceptionally valuable. At the same time your activities on the site generate very detailed information about you and your networks. If you are concerned about surveillance, this information can put you at risk.

Assess Your Facebook Mobile Risks

Like Twitter, Facebook is a way to get your messages to a potentially large audience. It is not a secure method of communication for sensitive information.

This article offers advice about how to mitigate risks when using Facebook as a dissemination and organizing tool. In particular, we consider the following risks:

  • The risk that your public activities on Facebook reveal compromising information about you or your networks - for example, revealing the identity of supporters or identifying people who were present at a particular event.
  • The risk of your private information being revealed to a third party without your consent.
  • The risk that your account details (username and password) are discovered, and that someone may impersonate you.
  • The risk of your account being deleted or suspended.
  • The risk that Facebook is blocked or becomes inaccessible.

in general, you should only use Facebook to share information that you consider public. Public information can be freely distributed by you, your organization, and your supporters, without any risk to individuals or organizational operations. In communicating public information, you can send and receive this information without taking any precautions.
