TED-ED: How to create cleaner coal - Emma Bryce

The video explores the role of coal in electricity generation and its environmental impact, including pollutants and climate change. It introduces cleaner coal technologies and Carbon Capture and Sequestration (CCS) as methods to reduce emissions. Despite the availability of these technologies, challenges such as cost and regulation hinder their widespread adoption. The video emphasizes the need for creative solutions and regulatory measures to mitigate coal's negative effects.
