Renewable Energy Resources_ Part 2 _ GCSE Physics

The video discusses geothermal and solar energy. Geothermal energy is derived from radioactive decay heating rocks, which can heat water to produce steam for electricity generation. It is environmentally friendly but geographically limited. Solar energy uses cells to convert light into electricity, suitable for remote areas but currently costly and inefficient. However, solar technology is becoming more affordable over time.
