Solar and Thermal Energy

Dr. Forrester introduces solar and thermal energy, explaining heat transfer methods: conduction, convection, and radiation. The video covers solar energy conversion into electricity and heat, using photovoltaic cells and solar panels. It concludes with a DIY solar oven project, demonstrating practical applications of solar energy.
