Chapter 1 Introduction 1.1 Renewable Energy Resources Self regenerative resources found in nature are called renewable. Energy that is resulting from natural process that is replenished constantly, Resources of renewable energy are sunlight, wind, tides and geothermal heat. Renewable energy exists continuously and abundant in the environment, ready to be harnessed, clean alternative to fossil fuels. Renewable energy put conventional energy in key four areas: Hot water/space heating, electricity production and transportation and off-grid energy services. The major renewable energy resources are the following. 1.1.1 Water Water energy or hydro energy is one of the renewable energy sources. Hydro energy is divided into three main categories: the …show more content…
Solar air heater is used to heat or condition air for building or process heat applications. Space heating for housing and commercial use can be done by the use of solar air heating technology to save money and energy. Solar air heater converts solar energy into thermal energy directly using solar collectors. The basic types of solar air heaters are single pass solar air heater and double pass solar air heaters and special modifications are used nowadays. • Single pass solar air heater is a simplest and distinctive form of air heaters. In single pass solar air heater, air enters through one end, flows in a single straight duct, absorbs heat and then heated air go out at the other end of the duct. There is a single straight channel of air. This is the simplest form of heater which is usually …show more content…
The air heater is made to work on solar energy which is a renewable form of energy. The process of room heating is must for every home and other residential and commercial area. The space heating with conventional fuels has turned out to be costly due to the raging fuel crisis. Hence an efficient solar air heating device must be created which can be used in residential and commercial areas. 1.5 The purpose of the study The purpose of the study is to understand the needs of humans in daily life and fulfill these needs by resources which are available in the universe. One of the resources which are free for everyone is solar energy. It is renewable form of energy. Solar energy is the most effective and useful energy nowadays to fulfill human needs. By using solar energy we fabricate solar air heater to give us more energy which has a lot of uses in industries and space heating for residential and commercial uses. 1.6 Objective • To design and fabricate double pass solar air heater. • The implementation of solar air heater for a normal
Fracking: The Fracturing of America (Introduction) Shaking wakes you up during the middle of the night. You open your eyes to scan the entire room searching for someone. No one to be found. The shaking continues and it grows stronger.
A solar panel can be used for many things, but the biggest thing is used for capturing the sun's energy in order to make it useful provide energy to the house, buildings even be sold back to the city or town you live in etc.. It works by collecting the sunlight throughout the day, then converts into energy that's usable, then the electricity travels to the net meter then the energy is used for anything. When having the solar panel on a roof you can use it for personal use or even sell it back to the electrical company and they’ll pay you. There are about 73,000 terawatts of energy shining down that's 10,000 times then what we use on daily bases. Perks of having solar panels it's a tax 30% tax write off, doesn’t need any fuel combustion, Securing your energy and not depending on National
Renewable energy sources have been emerging quickly in Iowa in recent years. There are three main examples renewable energy resource throughout the state which include wind, hydroelectric and solar energy,
When using a straight stream, water comes out of the hose in a solid column with a low amount of surface area. A straight stream absorbs more heat because of its low surface area. All substances will heat up faster, the larger the surface area a substance has. Think of wood for instance, sawdust has a greater surface area than a log of wood. Sawdust will burn up much faster than a log because of the amount of surface area absorbing heat.
Hydraulic Fracturing, otherwise known as fracking is the process of injecting large amounts of sand, water, and other chemicals into the shale rocks deep beneath the ground in order to flow natural gas back onto the surface of the well. This process was invented in the early 1900s, and has been controversial ever since. There are two sides to the debate, one being that fracking is known to be horrible for the environment. Fracking has caused families to need to be displaced, and emitted thousands of toxic chemicals into the air causing major public health issues. At the same time, fracking has reduced the reliability on coal, which is known to be horrible for the environment; it has also brought hundreds of thousands of gallons of natural gas
It can store and transport energy from any energy source. Hydrogen is not freely available in universe and it can be produced from water and other compounds. If hydrogen is producing from water, the energy which is required to produce it costs more than one can easily recover it from burning it.
Due to these issues, renewable resources should become our primary source of energy. First, there are many issues with the energies sources we use now, but one of the major ones is that nonrenewable resources cannot replenish fast enough to replace what is being consumed. Energies made from fossils are the most common types of nonrenewable resource. Specifically, the three main types of fossil fuels are coal, natural gas, and oil.
You may think that solar energy isn’t enough but we can use it with other clean energy. It is a wise choice to use solar energy because solar energy is renewable and abundant, it is environmentally friendly, and it is also available around the world. Solar is the most abundant energy resource on Earth. In Taiwan, a three-story building with solar panels can produce three to four families’ electricity.
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3)
Fossil fuels Fossil fuels are NOT a renewable energy resource it will finish up one day As once we 've burned them all, there isn 't any more, and our consumption of fossil fuels has nearly doubled every 20 years since 1900. This is a particular problem for Oil, because we also use it to make plastics and many other products Coal, Oil and Gas are called "fossil fuels" because they have been formed from the fossilized remains of prehistoric plants and animals.
For many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills..
2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
Water is one of the most important and vital substance on earth. All life forms on earth require water to survive. If there will be no water there would be no life on earth. Aside from drinking water to survive, people have many other uses for water.
