Passive systems, on the other hand, do not require any mechanical components and instead harness natural convection to distribute heat. These systems are often designed into building architecture to maximize energy efficiency.

The applications range from residential water heating to powering large-scale solar thermal power plants. Converting sunlight into thermal energy is particularly beneficial in regions with high solar insolation, where the demand for hot water or space heating aligns perfectly with energy supply. Thus, the impetus to expand solar thermal energy adoption is increasing, driven by the pressing need for sustainability and energy efficiency in our contemporary lifestyles.

4. CHEMICAL ENERGY FROM SOLAR POWER

Chemical energy production through solar energy represents an innovative approach to energy storage and conversion. Processes such as artificial photosynthesis, solar fuels, and thermochemical energy conversion exemplify how sunlight can drive chemical reactions, creating fuels like hydrogen or hydrocarbons. This transformation is critical for storing energy generated from intermittent renewable sources and for enabling the transition from fossil fuels.

In artificial photosynthesis, researchers simulate natural photosynthesis processes to combine sunlight, water, and carbon dioxide to create hydrocarbon fuels or hydrogen. This technique has the potential to produce carbon-neutral fuels, greatly reducing greenhouse gas emissions. Solar fuel systems not only utilize solar energy efficiently but also provide a pathway to decarbonizing energy consumption, which is essential in mitigating climate change.

Thermochemical energy conversion processes also use concentrated solar power to drive heat-intensive chemical reactions, producing syngas or other fuels.
