1. UNDERSTANDING SOLAR ENERGY

Solar energy is the most abundant source of energy available on Earth. Every hour, the sun emits enough energy to satisfy global energy demands for an entire year. This remarkable potential has prompted advances in technology and policy aimed at efficiently harnessing this natural resource. Solar energy originates from nuclear fusion reactions in the sun’s core, where hydrogen atoms combine to form helium, releasing tremendous amounts of energy. This energy travels over 93 million miles to reach our planet, delivering sunlight that can be harnessed using various technologies, primarily through solar panels and solar thermal systems.

The two main technologies for capturing solar energy are photovoltaic (PV) cells and concentrated solar power (CSP). Photovoltaic cells convert sunlight directly into electricity using semiconductor materials, typically silicon. In contrast, CSP employs mirrors or lenses to concentrate sunlight, generating heat that drives steam turbines to produce electricity. Both methods have unique advantages and challenges, determining their application based on geographical location, energy demand, and technological capability.

2. TECHNOLOGICAL ADVANCEMENTS IN SOLAR ENERGY

Recent advancements in solar technology have markedly increased energy conversion efficiency and reduced production costs.
