How do renewable energy sources work?
What renewable energy sources are, what physical phenomena they are based on, and how they operate within the power system. The lesson helps students understand the key advantages of renewable energy sources, debunks common myths about them, and shows the challenges associated with the development of renewable energy.
The lesson plans for high school classes were prepared by Jakub Wiech—a lawyer, journalist, and columnist specializing in the energy sector, editor-in-chief of the Energetyka24.com website, a popularizer of knowledge in this field, and the creator of the “Elektryfikacja” podcast.
After the lesson, students should know the answers to the following questions:
What are renewable energy sources, and how do they differ from fossil fuels?
How do photovoltaics, wind turbines, hydropower plants, and geothermal energy convert energy from the environment into usable energy?
Why do renewable energy sources have a low carbon footprint and low marginal cost of energy production?
What does the variability of renewable energy production mean, and why must the power system be flexible?
What are the most common myths about renewable energy sources, and how can they be verified?
Why are recycling, lifespan, and energy payback time of renewable energy installations important when assessing their environmental impact?
What role do energy storage systems, pumped-storage power plants, and demand-side management play in a system with a high share of renewables?
What is a prosumer, and how do distributed energy sources change the traditional energy model?
What technical, social, and spatial barriers hinder the development of renewable energy sources?
How can the development of renewable energy be reconciled with the need for stable, affordable, and secure electricity supply?
