What You Need To Know About 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.

How Can We Use the Energy in Biomass? There are a wide variety of uses for the energy in biomass, including basic life functions, direct combustion, and charcoal, liquid fuel, or gaseous fuel production. We are all familiar with the use of biomass for basic life functions by all animals and humans. All the food we eat contains biomass, whether vegetables, animals, or products derived from them. The energy in these foods is what sustains life in all living organisms. The focus of this Web site is more on the production of energy for residential, commercial, or industrial applications than for food.

What are the Many Forms of Energy? Energy is commonly defined as the capacity of a system or a body to do work. There are many forms of energy (to be described later), but any of them can be used to do work. For example the chemical energy in gasoline can be burned in an automobile engine to make the car move. Electrical energy can be used to turn a motor and make machinery move.

Solar Energy Basics Solar Energy Basics. Solar is the Latin word for sun—a powerful source of energy that can be used to heat, cool, and light our homes and businesses. That's because more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings.

Sources of Energy We use renewable energy sources mainly to make. electricity. Electricity and hydrogen are different from the other energy sources because they. are secondary sources of energy. Secondary sources of energy—energycarriers— are used to store, move, and deliver energy in easily usable form.

Water-Energy Connection The use of water and the use of energy are intricately intertwined. The extraction, treatment, distribution, and use of water followed by the collection and treatment of wastewater require a lot of energy; likewise, the production of energy—particularly hydroelectric and thermometric power generation— requires a lot of water. Saving Energy Saves Water. Water is used to turn turbines for hydropower, to produce steam for thermoelectric power, and to cool equipment by absorbing the waste ...

How the Body Uses Energy Energy System 1: Ready fuel for immediate energy. The Immediate Energy system, or ATP-PC, is the system the body uses to generate immediate energy. The energy source, phosphocreatine (PC), is stored within the tissues of the body. When exercise is done and energy is expended, PC is used to replenish ATP.

ATP ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.
