Solar Energy

Solar energy is radiant light and heat from the sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, and artificial photosynthesis.

Key Concepts

1. Sunlight as a Renewable Resource: The sun is an abundant and renewable source of energy, providing a sustainable alternative to fossil fuels.
2. Photovoltaic (PV) Cells: These cells convert sunlight directly into electricity using the photoelectric effect.
3. Solar Thermal Energy: This technology uses the sun’s energy to generate heat, which can be used for heating water, space heating, and industrial processes.
4. Solar Architecture: Designing buildings to harness and utilize solar energy efficiently through features such as solar panels and passive solar design.
5. Artificial Photosynthesis: This is a research field that aims to replicate the natural process of photosynthesis to produce energy-rich molecules from sunlight, water, and carbon dioxide.

Advantages of Solar Energy

• Renewable and Sustainable
• Reduces Greenhouse Gas Emissions
• Low Operating Costs
