Solar power is energy harnessed from the sun that can be transformed into different forms of energy, primarily thermal and electricity. Technologies such as photovoltaics (PV) convert sunlight directly into electrical power, while solar thermal systems capture solar heat for heating or electricity generation. Solar power is a clean, renewable resource because it produces no harmful greenhouse gas emissions during operation and comes from an abundant natural source. Around 30% of incoming solar radiation is reflected back into space, while about 47% is absorbed by the Earth’s surface, making solar energy a substantial contributor to Earth’s energy balance. The sun delivers more energy to Earth in one hour than the entire world uses in a year, emphasizing the massive potential of solar power as a sustainable energy solution. Solar power plays an increasingly important role in reducing reliance on fossil fuels and mitigating climate change impacts.
