Sports drinks: Hype or help? Date updated: April 03‚ 2007 Content provided by Revolution Health Group Energy drinks‚ sports drinks‚ recovery drinks…call them what you will‚ their names still suggest that they’re designed for hard-working athletes. These days‚ however‚ it seems that everyone is tipping them back. But who really needs them? "I recommend sports drinks for intense exercise that lasts for more than an hour‚" says Suzanne Farrell‚ R.D.‚ a registered dietitian and spokesperson for

using renewable energy to replace fossil fuel. In addition‚ renewable energy is generated by natural resources such as sunlight‚ wind and biomass which produce less or no pollution when generate energy. Furthermore‚ renewable energy will be demanded for approximately half of the worldwide electricity supplies to reduce CO2 emissions by 2050‚ which it is estimated by The International Energy Agency (Cited in Shi 2010). This essay will focus on two forms of renewable energies which are solar

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 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

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

Clean Energy is Possible First of all‚ energy comes from many sources like oil‚ coal‚ nuclear and wood. These four sources and others are dirty energy. There is clean energy like the solar‚ wind‚ water‚ and kinetic energy. Both of them cause bad or good problems I agree with writer with some points and I disagree with hem on other points. First I agree with him with the point the one that he talks about burning wood and coal causes a lot of pollution in the atmosphere also burning oil is dirty
