WORD COUNT: 6664 ENERGY SECURITY: CHALLENGES AND PROSPECTS IN BOTSWANA INTRODUCTION 1. Security is an important factor in life on a daily basis‚people require one form of security in a particular way or the other. There are issues of crime‚ terrorism‚ poverty‚ displacement‚ health‚ education and many others which a nation has to ensure that its citizens are satisfied with. Any longer interruption of a steady and plenty flow of energy‚ particularly modern energy would massively harm a

Energy Nothing can live without energy. People‚ animals and plants need energy to live and machines need energy to work. Today‚ most of the energy we use still comes from fossil fuels like coal‚ oil and gas‚ which have been formed underground over millions of years. We called these non-renewable forms of energy because they can only be used once. Because of this‚ we need to reduce our use of non-renewable fuel and use more renewable forms of energy like that from the sun‚ wind or geothermal

Nuclear energy… Boon or Bane ? Nuclear energy? Nowadays these two words are always sticking on the society’s mouth‚ but do they know the actual meaning of it? Nuclear energy is basically defined as the energy released by the reaction within the nuclei‚ as in nuclear fission or fusion. The core reason of using nuclear energy is to generate electric power to satisfy human needs. Usage of the nuclear power plant as an energy generator came together with several boons and banes. As quoted by the

Renewable energy is energy from natural resources such as sunlight‚ wind‚ rain‚ tides‚ and geothermal heat‚ these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five

Energy Outline A. Benefits Of Solar Energy • Does not release green house gases • Production of solar energy does not produce smoke‚ gas‚ or any other chemical byproducts • Solar energy contributes to about 4 percent of the world’s electricity • Italy’s Montalto di Castro solar park: o good example of how solar contributes to the decrease in emissions o Decreases the carbon emissions by about 20‚000 tons per year compared to fossil fuel energy production. • Money! o Except for the initial

Heat Heat is the transfer of energy from a hot object to a colder object‚ such as when toasting a slice of bread. The heat transfers onto the slice of bread which results in warm toast. When the slice of bread is heated‚ many things change; for example‚ the texture turns crunchy‚ the bread hardens‚ and the colour darkens. Where does the toast get its heat from? The toaster. Toaster A toaster is an electric small appliance designed to toast sliced bread by exposing it to heat. When a slice of bread

Alternative Energy Alternative Energy whether used for transportation or utilities such as generating electricity for home or business is a very significant subject going on right now because of the benefits it would provide for us‚ such as environmental‚ economic‚ job security and energy security. I believe alternative energy would be beneficial to our society‚ especially if it is used in transport; there is many other better‚ leaner and reusable energy sources out there‚ for example fuel for

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

I will be informing you about nuclear energy. Prior to giving this information‚ let’s look at some history. Ancient Greek philosophers were the first to come up with the idea that matter is made up of invisible particles. The Greeks called these invisible particles "atoms"‚ which is Greek for invisible. Scientists studied this idea in the 18th and 19th centuries. After many experiments physicists found out that atoms contain a large amount of energy. Ernest Rutherford‚ a British scientist

This rings true when talking about energy drinks. These products promise to provide heightened awareness‚ more energy‚ more endurance some even reference to the consumer you will have wings. So when consuming these products what are you really drinking? Do they provide the energy boost they promise? Are they harmful? Should the FDA do more investigating into the safety of these so-called energy drinks? These are questions I had going into this as a consumer of energy drinks myself‚ I was interested
