Energy is the ability to do work. It is essential
for powering various activities in our daily lives. The Sun provides solar
energy, plants use it to make food, and flowing water generates hydropower for
electricity. Wind turbines convert wind energy into electricity, while coal and
natural gas are burned to produce heat and power. Energy comes in forms like
heat, light, electrical, and mechanical. Heat energy warms things; light energy
helps us see. Electrical energy powers devices.
