Introduction to Personal Project Being a Grade 10 student at the American International School of Mozambique,I am required to do my Personal Project to complete the MYP curriculum before moving onto IB. I have chosen the environment as my topic for my personal project and I haveresearched on renewable energy. I have always tried to preserve nature because Iunderstand the importance of maintaining our environment. There have been numerousoccasions where our society has been very careless about sustaining resources. In thecoming years, the future generation of our world will be facing tremendous amounts ofadversities if we do not start to preserve mother nature immediately. Several countries andorganizations have already started to support this cause and have also started to takeaction. Our society has to start using renewable energy at any cost. My aim for this project to enlighten people on why it is crucial to understand therelevance of this topic. I will be discussing several advantages of renewable energy. I willtry to give advice on the basis of what I have learnt and researched about until now. If Isucceed in educating people on renewable energy, I will have achieved my goal.
Introduction to Renewable Energy Energy has two main forms: nonrenewable energy and renewable energy. “Nonrenewable energy is a natural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate, once depleted there is no more available for future needs.”(en.wikipedia.org) “Renewable Energy is any naturally occurring, theoretically inexhaustible source of energy, as biomass, solar, wind, tidal, wave, and hydroelectric power, that is not derived from fossil or nuclear fuel.” (dictionary.reference.com) In simple words, renewable energy is energy which can be reused whereas nonrenewable energy is energy which cannot be reused. Our resources such as coal and petroleum will soon be depleted and unless we already have a well – developed energy production system, our world might not survive such circumstances. (climatepedia.org) The rate at which we are consuming sources of energy is growing consistently and the prices of energy resources have also risen due to their decreasing abundance. (climatepedia.org) A relevant portion of our world is dependent on jobs pertaining to resources and if these people lose their jobs due to the curtailing energy sources, it will only add to the world’s economic crisis where thousands of people are still unemployed. (climatepedia.org) At this point of time, it is important to begin saving energy in any way we can to reduce the impacts of the diminishing resources in the future. (climatepedia.org)
History andBackgroundRenewable energy hascome a long way eventhough its relevance inour world was discoveredin the last few centuries. (blogs.triplealearning.c om) Fire was probably mankinds first discovery ever and also the first usage of renewable energy. As ape-man discovered fire, they used to burn dw.de/image/0,,15952422_401,00. jpg biomass which is leaves More than 2000 years ago, and wood to create fire. people living in India, China, (2greenenergy.com) and Rome built watermills to grind grains. The usage of hydrokinetics is still upheld in several unindustrialized parts of (4to40.com our world. The real difference ) today is extracting the same renewable energy without (top-alternative-energy- sources.com) harming aquatic life abound in the rivers and oceans.

Biomass It is energy obtained through organic material. Power plants burn biomass fuel (wood, landfill trash, and leaves) to heat water. The water transforms into steam which turns in a steam turbine to produce electricity. Cow manure is also being converted into biomass for production of energy. Solar Wood is the largest source of biomass fuel since everyone uses it, even in Power their homes. Photovoltaic cells, also known as solar Organic components from industrial cells, absorb the suns radiation using wastes are also being tried to be silicon. converted into biomass. This process involves the movement (greenenergychoice.com) and displacement of electrons to produce electricity. (renewableenergyworld.com) Large – scale mirrors are also used to absorb heat. The mirrors aid in heating water or producing steam to generate electricity (hydropower) (greenenergychoice.com)
Hydropower About 73% of all renewable energy sources Generated by flowing water Water pushes through a piping called a penstock which turns the generator on. Consists of wave and tidal energy Scientists are trying to control energy produced by the movement of the ocean. Geothermal Dams are constructed to exploit the flowing water. Energy E.g.: The largest dam in the US – The In other words, it is the heat from the Hoover Dam earth. (greenenergychoice.com) Extremely pure and sustainable Geothermal energy is trapped underground. It rises above the surface and produces heat or steam which is harnessed to generate electricity. (greenenergychoice.com) (renewableenergyworld.com)
Wind Power Oth A simple process which involves the ers movement of wind turbines to Ocean energy: produce energy. - It produces two types of energy – The energy is supplied into a thermal and mechanical energy. generator which is converted once - Thermal energy is obtained from the again into electricity. suns rays on the surface of the water. The electricity is stored in power - Mechanical energy is obtained grids supplied to the power station. through the tides and waves of the ocean. Wind power had the most potential - The ocean is the world’s largest since there is a huge amount of sunlight collector since it covers 70% land including consistent wind of the earth. movements. - Energy is stored using hot vapors from the warm water of the ocean. (greenenergychoice.com) - In some systems, the water is boiled and the steam is collected through turbines which is converted into energy. - In mechanical energy, the tides are controlled by the gravitational pull of the moon, and the waves are controlled by wave. - Mechanical devices are used for the energy created by the waves and tides.
Advantages The renewable resources are nearly infinite. Renewable energy sources have low carbon emissions and thus, a lower impact on the environment. Fossil fuel have virulent effects on the environment such as “smog, acid rain, and global warming”. (climatepedia.org) Its usage aids in creating job opportunities for the people. Economic growth is assured. The non – renewable energy sources will diminish in a couple years, leaving us without any established resources. You do not have to rely on other countries for these resources as they can be easily found in any country. The price of electricity will rise since the prices of crude oil are likely to rise as well. A better energy resource would be needed immediately when this happens. People who support environmental friendly ways can receive special advantages such as tax waivers and credit deductions. Less maintenance is needed in renewable energy wind farms than in mechanical machines. (solarschool.net) (conserve-energy-future.com)
Disadvantages Sunlight is only found during the daytime which makes it inconvenient to use at night. Geothermal energy has damaging side effects since if the toxins found in the surface of the earth emerge, they can become hazardous. The initial costs of setting up a plant are quite expensive. The cost of the construction of dams is not cheap. Wildlife and the natural flow of water is affected by the construction of dams. Wind energy is not as reliable as it seems since an ideal location must be chosen to create the wind farm. The wind farms will most certainly have an impact on the bird population since they can prove to be fatal. It might be a bit difficult to produce a large amount of energy which will sustain a large population. Renewable energy depends on the weather greatly which makes it difficult to obtain during different circumstances. An example would be the necessity of rain to produce energy in hydroelectric dams. A clear sky would be needed for solar energy. (solarschools.net)
IEA (International EnergyAgency) Based in Paris, it is a self-governed organization which was established in 1974 due to the oil crisis which occurred in 1973. It serves as an informational source about the international energy sectors. There are 28 member states but it cooperates with non- members as well such as India, China, and Russia. Its main focus has been summarized in the 3E’s or three policies which are energy security, economic development, and environmental protection. Energy security is the promotion of flexibility and diversity in all energy sectors. Environmental awareness handles the knowledge of climate changes and problems acquainted with it. Engagement worldwide is the collaboration of member states, the producers and consumers, to resolve energy
The Future “The future belongs to renewable energy” (Brad Collins, Executive Director of the American Solar Energy Society) The advantages of renewable energy sources must overrule the disadvantages of the non – renewable energy sources. Our future generations will suffer a lot if we do not take action immediately. We must realize that energy is precious and that an equilibrium is required in all aspects of life. We must use renewable in abundance and non – renewable energy sources in limitations. We will save quite a lot of money if we implement environmental friendly ideas. We will be able to effectively reduce air pollution which is a growing concern in today’s world. (botany.uwc.ac.za)
