This paper investigates the connection between marketing communication and citizen information with renewable energy sources. Marketing professionals through marketing channels, and with the help of various marketing communication tools in combination, have the task of conveying the message to the desired market or the market in general. A marketing communication tool can be anything from advertising, personal selling, direct marketing, sponsorship, communication, and sales promotion to public relations (Ay, Aytekin, & Nardali, 2010). Marketing management is key to the successful management of a company and its strategic development. The essence is to investigate how marketing communication is related to informing citizens about renewable energy sources (RES), what is the advantage of RES in relation to the shortcomings of the so-called. "Green energy" taking into account several factors from production to disposal of waste from this type of technology compared to other types. Thus, to investigate the existing theoretical assumptions of marketing communication and prove the impact on citizens' awareness of RES. In assessing public attitudes towards renewable energy, the information gathered clarified respondents' attitudes towards issues such as general knowledge about renewable energy and energy production, government and personal incentives, a comparison of fossil fuel and renewable energy use, and opinions on subsidies. Based on the analysis of previous research and the implementation of independent research, the author confirmed the working hypothesis which reads: Systematic management of marketing communication channels RES are perceived in the minds of consumers as "green energy", cheap energy that does not pollute or harm the environment. The limitations of this research lie in the fact that a small number of respondents were surveyed, so the number of people being surveyed should be increased in the future.
