Question

explain the origin of solar energy ​

Answer 1

In theory, solar energy was used by humans as early as 7th century B.C. when history tells us that humans used sunlight to light fires with magnifying glass materials. Later, in 3rd century B.C., the Greeks and Romans were known to harness solar power with mirrors to light torches for religious ceremonies.

Answer 2

Answer:

Solar energy is the radiant heat and light from the Sun that is captured by a variety of technologies, including solar architecture, solar thermal energy (including solar water heating), and solar power to produce electricity.

Explanation:

• It is a crucial source of renewable energy and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies are often classified as passive solar or active solar.
• Utilizing photovoltaic systems, concentrated solar electricity, and solar water heating are examples of active solar approaches.
• A building's orientation toward the Sun, the use of materials with favourable thermal mass or light-dispersing qualities, and the creation of naturally ventilated rooms are all examples of passive solar approaches.

Because of how much solar energy is available, it is a very alluring source of electricity. Since 2021, solar energy has been less expensive than fossil fuels.
