Teaching method

Theorico-practical classes in classrooms with oral communication of the teaching programme and resolution of problems. Teaching activity supprted by a webpage in Moodle@FCT platform where all the teaching materials are available (slides of classes; solved problems; additional problems; tests). Also, group works are done in order to promote the autonomous team work.

Evaluation method

Three group works are performed during the semester, each one with a relative weight of 20% in the final score. One final individual test is done with a relative weight of 40% in the final score.

Subject matter

1. Significance of the bioenergy in a global energy market. Biomass definitions. Bioenergy definitions. Political and legislative instruments. Strategic objectives. Sustainability, security, competitiveness and infrastructures.
