The developing economies of the world are largely located in geographical regions that have abundant renewable energy resources, be they solar, wind, hydro or in some cases geothermal, yet paradoxically at the individual and rural community level, access to energy is often a very real issue. Establishing a continuous chain of temperature controlled cold environments from the point of harvest to the marketplace and on into the home, a ‘cold chain’, is what is required in order to avoid produce spoilage and to connect farmers with higher value market options in distant urban centres or overseas.
