Rubbish can power Africa's cities
Energy generated from rubbish could power an estimated 40 million households across Africa by 2025, proposes a study.
"Our analysis shows that waste, and in particular municipal solid waste, is a renewable energy resource that could provide a meaningful share of both gross energy consumption and electricity on the African continent," says study author Fabio Monforti-Ferrario, from the European Commission's in-house science service, the Joint Research Centre.

Eskom update: Summer holidays seem bright, low chance of outages
The national power utility Eskom, has boasted that through teamwork and the public’s mindfulness of electricity consumption, the utility has achieved 99 consecutive days without power outages, apart from a two hour and twenty minute lapse in September.

Organic solar panels — a smarter way to a truly brighter future
These organic photovoltaics differ from silicon solar cells as they can be made entirely from synthesised organic materials, which are deposited on to cheap substrates such as PET, a form of polyester used in soft drink bottles and crisp packets. This material is lighter, more flexible and can be tuned to provide different colours — who said solar cells have to be black?
Critically, it takes just one day for organic photovoltaics to earn back the energy invested in their manufacture, known as "energy payback time", which compares to about one to two years for regular silicon solar cells.

Eskom must find way of becoming part of renewables "in a big way"
A senior Eskom official has made the case for the utility playing a more active role in deployment of large and small-scale renewable-energy solutions in South Africa, suggesting that previous arguments against its participation in the sector were becoming less relevant.
In fact, Barry MacColl, who is GM for Eskom’s research, testing and consulting business, said on Thursday that the state-owned utility’s very survival would depend on its ability to adapt to changes being brought about in the electricity sector as a result of the rapid growth of renewables, as well as by the increased integration of information and communication technologies, and changing customer preferences.
