From which type of energy can electrical energy be derived?

Electrical energy can be derived from several sources, but in the context of the options provided, light energy is a key source, particularly through processes such as photovoltaic effects. This is the principle behind solar panels, where light energy from the sun is converted into electrical energy.

Photovoltaic cells contain materials that generate electrical current when exposed to light. This conversion is a fundamental mechanism in renewable energy production, showcasing how light energy can directly lead to the generation of electrical energy.

The other forms of energy listed still have applications in energy generation. For instance, thermal energy can be converted to electrical energy through steam turbines in power plants, chemical energy is converted to electrical energy in batteries, and sound energy is generally less efficient and is not commonly utilized for electrical generation in practical applications. However, the focus on light energy highlights a very modern and increasingly important method of deriving electrical energy.
