This factfile gives an introduction to the various types of solar power available.
Sunlight is the world’s largest energy source (170,000 TWth) and the amount that can be readily accessed with existing technology greatly exceeds the world’s primary energy consumption. Sunlight is free, clean, endless and technically exploitable in most of the inhabited earth. Whilst today in the UK solar power is only economic in high value niche applications, growth is being achieved where subsidies are available. Projections show the potential to achieve economic viability for a significant generation share, particularly in emerging economies.
