Sustainable Energy 1. How can electricity be defined? Electricity can be defined as the flow of electrical power or charge. It is a type of energy fuelled by the flow of electrons from positive and negative points within a conductor. 2. What is an electrical circuit? 3. What components are required to create an electrical circuit? In order to create an electrical circuit‚ you need: a) A source of electric power (battery or generator) b) A load to absorb the power (lamp

Energy conservation helps ensure available resources for future generations and also helps prevent pollution. Most of our current energy sources today are not renewable‚ which means that they will eventually deplete. As a member of the Home Owner’s Association I believe that it is extremely important for us to educate our community about the importance of energy conservation. Teaching the community that energy is not a right but a privilege will educate‚ empower‚ and make us aware of the importance

Energy Lab On November 13th‚ we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time‚ we weighed : a marble‚ a bouncy ball‚

Question: Energy is the main culprit of environmental degradation. Energy usage is undeniably a major contributor of environmental degradation‚ as large quantities of carbon dioxide and other waste products are emitted that ultimately causes a multitude of environmental problems‚ especially global warming. Energy and the environment are inextricably linked due to a carbon dynamics‚ where energy usage results in carbon dioxide emissions which accumulate in the atmosphere (Appendix A). Over time

Renewable sources of energy Wind energy Wind Energy‚ energy contained in the force of the winds blowing across the earth’s surface. When harnessed‚ wind energy can be converted into mechanical energy for performing work such as pumping water‚ grinding grain‚ and milling lumber. By connecting a spinning rotor (an assembly of blades attached to a hub) to an electric generator‚ modern wind turbines convert wind energy‚ which turns the rotor‚ into electrical energy. Because wind is a clean and

behind Energy Drinks 1. When we say that something gives us "energy”‚ what does that mean? What is a biological definition of energy? When we say that something gives us “energy” it means we can get sugars or carbohydrates and lipids from that. Humans need to eat carbohydrates and lipids to provide fuel for our body’s metabolism. Human body must have these chemicals in order to function and different food sources provide different types of energy. The biological definition of energy is the

we have had a certain amount of new "alternative energy resources" been introduced to us. These new energy sources range from using almost all natural resources as suppliers. Some are quite complex while others just needed a little brainpower. One quite complex energy source is one of geothermal energy. Harnessing geothermal energy is an art in itself. It is the process of capturing the Earth’s internal heat in the core. This and many other energy sources are being implemented today to build a better
