While it may be unpopular, nearly everyone has had to do homework. Yet for those living in communities with no or intermittent access to electricity, the ability to study at home is sometimes a luxury.
Often, children have no choice but to use harmful kerosene lamps to provide light so that they can study during the evening. This is far from ideal. There are a raft of respiratory and health risks associated with using kerosene in the home. The Climate and Clean Air Coalition has stated that, "Users of kerosene lamps pay a huge price in terms of human well-being."
With such conditions, progress at school inevitably stagnates.
In Cambodia, French non-profit association Lumières sur le Mékong – or Lights on the Mekong – has been using renewable energy to try and provide an alternative to kerosene lamps as study aids.
The organization provides solar panels to schools in rural Cambodia, where around 90 percent of the country's poor and near-poor live, according to the World Bank.
These panels are used to power lamps and batteries in schools, as well as charge portable lamps that children can take home to use as study aids. Pupils bring the lamps – which are provided by Lumières sur le Mékong and manufactured by Khmer Solar – back to school the next day to re-charge.
