Hi everyone ! My name is Sophie. Today, I'm going to talk about solar energy. Solar energy, which radiates light and heat from the Sun, has been harnessed by humans since ancient times using an ever-evolving range of technologies. Solar radiation, along with solar secondary resources such as wind and wave power, water power, and biomass, make up most of the renewable energy available on Earth. Only a very small fraction of the available solar energy is used. Solar power means electricity generation based on heat engines and photovoltaic cells. Solar energy use is limited only by human ingenuity. Partial list of solar applications for space heating and cooling through solar architecture, through drinking water distillation and disinfection, daylighting, solar hot water , solar cooking, and high temperature process heat for industrial purposes. To collect solar energy, the most common way is to use solar panels. volume. A solar chimney (or thermal chimney, in this context) is a passive solar ventilation system consisting of a vertical shaft connecting the interior and exterior of a building. Due to the heating of the chimney, the air inside is heated causing an updraft that pulls the air through the building. Efficiency can be improved by using glass and thermoset materials in a way that mimics a greenhouse. Solar energy can be used in a stable water pond to treat wastewater without chemicals or electricity. An added environmental advantage is that algae grow in such ponds and consume carbon dioxide during photosynthesis, although algae can produce toxic chemicals that render the water unusable.
Thanks for your listening !
