Cuba will begin production this year of solar-powered freezers, after successfully manufacturing a prototype in 2010. This appliance ensures considerable savings of electrical energy. The new freezer will be a boon to hotels and to isolated homes, and can operate for a short time even in adverse conditions like storms because they can store energy.

Geovanny Rojas, vice-president for technology development at the Ministry of Steel's industrial group for refrigeration and heating, confirmed to Tierramérica that the first batch for 2011 includes 10 eco-freezers.

Each unit allows savings of 700 kilowatts/hour annually compared to conventional freezers.
