CBSE Class 10 Science Notes Chapter 14: Sources of Energy

Science Chapter 14 CBSE Class 10 Notes are based on the latest CBSE guidelines and latest syllabus, these notes will help students to revise the topics they have studied in brief. The chapter is important to teach how the energy is formed, what is the process and what are the sources, all types of sources, and the power plants to convert the sources into energy or electricity, thermal power plants use heat energy to produce electricity, hydroelectric power plant use water flow to produce energy, and windmills are used to convert airflow into electricity, solar panels, etc. Some of the sources are renewable and some are non-renewable. Some sources are also hazardous to the environment like fossil fuels when burnt they produce a lot of air pollution and it is also one of the biggest causes of global warming.
