The article is devoted to the analysis of the research about the share of renewable energy in energy production as well as the use of solar energy for electricity generation in the Kazakh energy sector. The study results were compared with analogous data obtained in relation to Latvia and the European Union. The impact of electricity obtained from solar energy as well as energy efficiency impact on CO2 emissions reduction directly in food industry is calculated. During the study specific indicators in Latvia and Kazakhstan are compared using the comparison method. The study showed that Kazakhstan has great potential for solar energy in electricity production to cover part of the electricity consumed in the food industry.
