Potential for renewable energy–assisted harvesting of potatoes in Scotland

Depleting energy resources, enhancing energy security and energy access and approaching climate change related challenges are some of the present day challenges. Against this backdrop, renewable energy (RE)-based farming has been a topic of serious discussion within Great Britain and Scotland. There are multiple advantages in the development and applications of RE micro-grids for farming communities as often they are located in areas that are quite remote and hence their energy sustainability provides security of supply. In the present article, a large-scale RE system that included solar photovoltaic and wind turbine has been critically analyzed with respect to its fractional contribution toward the total energy budget of a potato farm that produces 8000 tons of crops annually, with 4500 tons of the produce in cold storage for up to 8 months. The findings and recommendations from these case studies will help renewable energy practitioners in erecting and analyzing similar installations.
