Geothermal energy needs to be near a heat source, typically from the Earth's mantle, that can produce hot water or steam to drive turbines and generate electricity. Additional factors like permeable rock formations are also important for successful geothermal energy operations.
Geothermal energy faces challenges such as location constraints, high initial investment costs, and uncertainty in resource availability. The technology also requires specialized skills and expertise for development and operation, further limiting its widespread adoption as a main energy source compared to other renewable energy sources like solar or wind.
Fossil fuels are the main source of energy for many people because they are relatively inexpensive to extract and produce large amounts of energy when burned. They are also widely available and have a long history of use, making them a familiar and convenient choice for meeting energy needs. Additionally, existing infrastructure for extracting, transporting, and using fossil fuels makes them a preferred choice for many energy systems.
Nuclear energy is the second largest source of energy after fossil fuels. It generates electricity through nuclear reactions, providing a significant portion of the world's energy needs.

The ultimate source of energy for everything on Earth is the Sun. Plants convert solar energy into chemical energy through photosynthesis, which is then transferred through the food chain to other organisms for their energy needs.
Since we are dealing with a wave in a medium, therefore energy is needed to move the mass of the medium.The source of the energy varies - an earthquake, tapping a drumskin, your vocal chords, the wind on the ocean, a violin string and so on.
Red blood cells (RBCs) primarily rely on glucose for their energy needs. Glucose is metabolized through a process called glycolysis to produce ATP, which is the main source of energy for RBCs to carry out their functions, such as transporting oxygen throughout the body.

India primarily uses coal as the main source of energy for its needs.

Because the plant needs the leaves to absorb sunlight and turn it into energy, it takes a lot of energy to produce the fruit, so it needs a lot of leaves to produce that energy.
A person needs a motor when there is a need for mechanical energy with availability of a power source.
