If we are eating plants, we are consuming a primary source of energy, as these organisms use photosynthesis to capture the sun’s energy, which is then stored in their cells. When we eat food, we are consuming a form of stored chemical energy. We can find available energy all over the world. But the energy we use in everyday life comes from a variety of sources that have captured and stored this initial energy. Ultimately, nearly all energy comes from the sun, where nuclear fusion reactions create massive amounts of energy as atoms are fused in the core and released out towards Earth. Even when we are not paying attention to it, energy is present, regulating body functions while at rest or powering your household appliances even if they are turned off.Įnergy is all around us. In society, energy is needed for everything from driving to watching television to keeping homes and businesses lit with artificial light.Įnergy is needed for almost anything and everything in life. Going a little deeper into the human body, energy is needed to produce enzymes, contract and move muscles, and carry electrical impulses between cells. It repairs cells and body tissue, is used to build muscle, and is necessary to maintain homeostasis - and the harsher the environment, the more energy is needed to maintain this. Energy is in everything that we eat, consume, or use.Įnergy fuels and regulates the body’s natural internal functions. First and foremost, it is needed to simply stay alive. It’s also necessary in abundance for all types of modern conveniences, from light bulbs to appliances to vehicles. Energy is necessary for getting up out of bed, walking down the street, or even lifting your finger. We use energy to not only heat our human-made structures but we use it to cool them as well. Why Is Energy So Important in Our Lives?Įnergy is so important in our daily lives because it is a basic human need. This energy may come directly, such as in the form of photosynthesis, or indirectly, such as in the form of fossil fuels, which long ago trapped the energy of the sun that is released when burned. ![]() On Earth, the sun is the ultimate source of all energy that is available and used by people, animals, plants, and microorganisms. Why Is Energy Important?Įnergy is essential for all life and all processes that occur across the entire universe. It is actually transferred between states and from one form or object to the next, always doing work on the objects in the process. It can be measured and stored in various ways, but it is not a material substance, even though it can be converted directly into matter.Īlthough we often hear or read about energy consumption, it’s never really consumed. E nergy is the quantitative amount of work that must be done to an object to create these components.Įnergy is also a conserved quantity with a finite amount in the universe, though there is a near limitless supply. ![]() There are three main components of work: force, displacement, and cause. Work in this context is when a force acts upon an object to cause a displacement of the object. Simply put, energy is the ability to do work. But what is energy? Though we are constantly surrounded by it, the nature of this elusive yet omnipresent force is often misunderstood - or not thought about at all. It’s responsible for making everything happen, whether you want to use any household appliance, take a walk through the park, drive your car across town, or do anything that involves movement or activity.
