Home solar power offers affordable, safe electricity in Cambodia

Article: Home solar power offers affordable, safe electricity in Cambodia

In the developed world, renewable energy technologies have to compete with existing infrastructure based on fossil fuels or nuclear power. In the developing world, however, power grids and centralized power stations are often in poor shape or non-existent, so technologies like solar and wind play on a much more level playing field. Cambodia’s grid was relatively primitive from the start, and decades of warfare have degraded it even further; as a result, over 11 million people have no access to it.

In this kind of setting, solar power often works as a safe, affordable means of providing the most basic electric “luxury”: lighting.
