Why do we need energy in our daily activities?
Energy is an essential part of our daily lives! We use energy to heat and cool our homes, schools, and businesses. Animals and people eat the plants and use the energy that was stored. Food is fuel for our bodies’ energy needs like muscle power.
What is energy Why do we need energy?
Energy fuels your body’s internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body’s most important nutrient, helps facilitate the chemical reactions that produce energy from food.
Which body part uses most energy?
the brain
Why do we need energy giving food?
Foods and nutrients. A food is something that provides nutrients. energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
Where do we use energy?
We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
What is water energy?
Water energy is energy derived from the power of water, most often its motion. Energy sources using water have been around for thousands of years in the form of water clocks and waterwheels. A more recent innovation has been hydroelectricity, or the electricity produced by the flow of water over dams.

What are the uses of water energy?
Hydroelectricity is the application of hydropower to generate electricity. It is the primary use of hydropower today. Hydroelectric power plants can include a reservoir (generally created by a dam) to exploit the energy of falling water, or can use the kinetic energy of water as in run-of-the-river hydroelectricity.
What energy source is water?
Hydropower
Why is water energy important?
Hydropower is fueled by water, so it’s a clean fuel source, meaning it won’t pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions.
