The Sun’s energy is effectively limitless. While resources such as coal or gas are finite, if you are able to capture and use solar power it doesn’t prevent anyone else from also using as much sunshine as they need. Except that isn’t quite the full story.
This means that in a reliable electric power system (one that already meets its planning and operating reserve requirements) the addition of wind or solar requires no additional generation capacity to accommodate variability of wind or solar.
The key cost arises from the storage and transportation of solar power and an inherent contradiction of solar energy. The issue or contradiction of solar energy is that it generates power when there is sunlight but it is at this time that we need the least power.
In our recent study, we used a computer program to model the Earth system and simulate how hypothetical enormous solar farms covering 20% of the Sahara would affect solar power generation around the world. A photovoltaic (PV) solar panel is dark-coloured and so absorbs much more heat than reflective desert sand.
Studies and recent operational experience have found that when providing active power control, wind and solar can provide a verylarge fraction of a system’s energy without a reduction in reliability .
