Using energy-efficient LED light bulbs would minimize the energy used to light a building compared to incandescent or halogen bulbs. LED bulbs consume less electricity and have a longer lifespan, making them a more sustainable and cost-effective lighting option for buildings.
When a light bulb is turned on, electrical energy is transformed into light (radiant) energy and heat energy. This conversion process results in changes in energy form but the total energy remains constant, following the law of conservation of energy.
The energy in a flashlight changes form in the following order: chemical energy stored in the batteries is converted into electrical energy, which powers the light bulb to produce light energy.
A bonfire produces mainly thermal energy in the form of heat and light. The burning of the wood releases stored chemical energy in the form of heat and light energy.
Building a bonfire involves converting chemical energy stored in the wood into thermal energy (heat) and light energy through combustion. Initially, the potential energy in the wood is transformed into kinetic energy as the wood is broken and arranged. When ignited, this stored chemical energy is released through a chemical reaction, producing heat and light as byproducts.
In a flashlight, the energy transfer occurs in the following order: chemical energy from the battery is converted into electrical energy by the circuit, which then powers the light bulb to produce light energy and heat energy.

Light retrofitting can improve energy efficiency in a commercial building by replacing outdated lighting fixtures with energy-efficient LED lights. LED lights consume less energy, produce less heat, and have a longer lifespan compared to traditional lighting options. This can result in reduced energy consumption and lower electricity bills for the building, ultimately leading to improved energy efficiency.
Nuclear energy is the only energy that the human body does not produce.
Chloroplasts are the organelles that carry out photosynthesis in plant cells, converting light energy into chemical energy in the form of glucose.

A photon is a fundamental particle of light that carries energy. It behaves both as a particle and a wave, and is the basic unit of light. When light is emitted or absorbed, it is done in discrete packets of energy called photons. In essence, photons are the building blocks of light.
