GENEVA (IDN) – Amidst the gloomy news in the deteriorating climate change situation, is this bright spark – the cost of solar energy has been going down dramatically. This source of clean and renewable energy is seen as one of the major saviours that could help power the world without emitting greenhouse gases.
The drawback is that solar energy has traditionally been more expensive to use carbon-intensive coal or oil. But in recent years solar power has become much cheaper. Energy experts predict that its cost could match that of conventional fuels in the next few years in some areas.
