Correct option is A
Energy can be harnessed from the following sources:
A. Sun: Solar energy is a major renewable energy source, harnessed through solar panels and other solar technologies.
B. Sea: Tidal and wave energy are forms of energy that can be harnessed from the sea. These involve capturing the kinetic energy of water movements for power generation.
C. Animal excreta: Biomass energy can be derived from animal waste, which can be used to generate biogas.
Information Booster:
Solar Energy (Sun): The sun is an abundant and clean source of energy. Solar panels and solar thermal systems convert sunlight into electricity or heat, making it one of the most widely used renewable energy sources globally.
Tidal and Wave Energy (Sea): The sea provides immense potential for generating energy through tidal and wave power. Tidal energy is harnessed from the rise and fall of ocean tides, while wave energy captures the motion of surface waves, both of which are used to generate electricity.
Biogas from Animal Excreta: Animal excreta is an essential source for biogas production. Through the process of anaerobic digestion, animal waste is converted into methane, which can be used for cooking, heating, and electricity generation. This process helps reduce waste and generates renewable energy.
Sustainability of Biomass: Animal excreta as a renewable resource supports sustainable waste management. Utilizing waste for energy reduces the environmental impact of traditional waste disposal methods and provides an eco-friendly alternative.
Energy Efficiency: Solar energy and biogas are key to reducing carbon footprints and promoting energy independence. Solar power systems, once installed, require minimal maintenance, while biogas systems provide a reliable source of energy from organic waste.
Additional Knoledge:
D. Soil: Soil itself does not directly generate energy. However, biogas production involves organic waste, including agricultural waste, which may be sourced from soil-related activities, but it is not a direct source of energy.
