Energy is used in everything we do, but some examples are........in our food::all food has energy or in a light bulb or something electrical.
Geothermal energy might be a good energy sources and it might be commonly used in the future because there are clearly no disadvantages to geothermal energy.
Electricity!
we might be used to it, or its better to some people
wind power energy may be used by using it to brush your teeth because it helps the energy of the water create wind from the water/wind power energy.
Electromagnetic energy is just a name used to describe various forms of energy that are related to electricity & magnetism. So electromagnetic energy might include the kinetic energy of moving charges, or the potential energy between charges or magnets or it might refer to the energy of radiation, which is neither kinetic or potential energy.
Other factors that might affect energy usage include the type of appliances and electronics used, the energy efficiency of the building or home, the climate and weather conditions, the number of occupants, and energy-saving habits of the occupants.
A Biochemist might study how energy is used in athletes during competition since they study chemical processes, and reactions in living organisms.
The equipment might have circuits which remain energised when it is in an off-cycle, but the energy used would probably be less than 1% of the energy used in the on-cycle.
Magma can be a source of energy through geothermal power plants, which harness the heat from magma beneath the Earth's surface to generate electricity. This process involves tapping into the high temperatures of magma to produce steam, which then drives turbines connected to generators to create electricity.
Growing plants to use for energy uses land that can be used for growing food.Burning plants produces greenhouse gases.
It seems there might be a typo in your question. If you meant "calorie," it is a unit of energy used to measure the energy content of food and beverages. Calories are essential for providing the energy our bodies need to function.
"Renewable energy" refers to any type of energy that can be used for thousands of years, and that won't run out in a few generations, as will eventually happen with petroleum (oil). It might include things such as solar energy, eolic (wind) energy, hydraulic energy, wave energy, and geothermal energy.
