Alternative energy sources (AES) are a dynamic segment of innovative technologies that can replace conventional energy sources. SEVEn offers independent advice on the use of alternative energy sources, new policy development, analysis of technical-economic parameters of the solutions under consideration or technical assistance to investors in the preparation of specific projects (focused on electricity or heat generation or other forms of energy such as alternative fuels). SEVEn's primary goal is to find AES at the same or lower economic cost. SEVEn is engaged in renewable energy sources (RES) and secondary energy sources (SES), especially waste. Last but not least, SEVEn deals with alternative sources of energy in transport and eliminates barriers to their wider application.
