Question

all the sources of energy present on the earth are the outcomes of solar energy.justify this statement with examples.

Answer 1

The energy of the sun or solar energy is the original source of most of the energy found on earth.

• We get solar heat energy from the sun directly.
• sunlight can also be used to produce electricity from solar cells.
• The sun heats the earth's surface and the Earth heats the air above it, causing wind energy.
• plants undergo photosynthesis and prepare their own food. thus plants also get their energy from the sun.
• all the energy from plants flows through the food chain to animals at different levels so ultimately we all derive energy from the sun or solar energy.

hence, all the sources of energy present on the earth are the outcomes of solar energy.
