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…
The main biomass fuel that is well known is wood and byproducts. The min method to produce biomass energy is from the thermal treatment (i.e. incineration, gasification and pyrolysis), biomedical processing and chemical treatment. 1.2 Why solar energy Project related to solar energy is selected here because it has too many advantages over other conventional and renewable energies some of them are stated here 1.2.1 Renewable energy Solar energy is a renewable energy source this means that we cannot run out of solar energy as conflicting to non renewable energy source. 1.2.2 Abundant The prospective of solar energy is afar thoughts. The surface of earth receives 120,000 terawatts of solar radiation which is 20,000 times more than what is desirable to supply the entire world [2]. 1.2.3 Sustainable As abundant and renewable energy source is also sustainable. Sustainable energy source meet the requirements of the present without compromising the capability of future generations to assemble their needs. 1.2.4 Environmental friendly Harnessing solar energy does not cause pollution. However their emissions connected with the mechanized, shipping and setting up of solar power system are almost nothing compared to most conventional energy…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
