*****If you are having trouble accessing this page use the root URL at https://www.coursehero.com/study-guides/earthscience ***** Earth science is the study of our home planet and all of its components: its lands, waters, atmosphere, and interior. In this book, some chapters are devoted to the processes that shape the lands and impact people. Other chapters depict the processes of the atmosphere and its relationship to the planet’s surface and all our living creatures. For as long as people have been on the planet, humans have had to live within Earth’s boundaries. Now human life is having a profound effect on the planet. Several chapters are devoted to the effect people have on the planet. Chapters at the end of the book will explore the universe beyond Earth: planets and their satellites, stars, galaxies, and beyond.

In this course you will start by identifying the different steps a HVAC (Heating, Ventilation and Air Conditioning) engineers need to follow to come to a proper design while collaborating with the architect.

You will then learn how to distribute heat and cold using air and water systems, what temperature levels to use in both and how that relates to the type of energy supply and to the thermal quality of the building construction. You will further deepen your knowledge on air handling units and how to humidify and dehumidify air when needed and what that does mean for the energy consumption. As ventilation systems are often responsible for local thermal discomfort, you will also discover how different distribution systems lead to different comfort experiences and different indoor air qualities and you will know which simple control techniques can be applied.

Finally you will study a modern complex system consisting of an aquifer thermal storage, heat pump, boiler, solar collector, PV-cells, air handling unit, water and air distribution systems. This will allow you to develop skills to catch the complexity of such HVAC systems and to understand the basic rules of how to control them to get the best out of them and how to use data from the Building Energy Management System to help you in this task.

Young children are not likely to think past their piggy banks when it comes to safe places to set money aside for those special items. In this short course from our Ella's Adventures series, your students will learn that a bank account offers security and a return on their savings.

Much of the general population believes that the energy sources we depend on are perpetual. While people believe that energy use is the culprit for environmental damage, they are not aware of the methods and principles by which energy conversion devices operate. This course will provide you with knowledge and information on the main operating principles of devices/appliances in common use and will help you in making energy efficient and economical choices. The objective of the course is to expose you to energy efficiency in day to day life in order to save money and energy and thereby protect the environment. I hope the information in this course will help you become an environmentally-responsible individual of this Global Village.

This course examines the choices and constraints regarding sources and uses of energy by households, firms, and governments through a number of frameworks to describe and explain behavior at various levels of aggregation. Examples include a wide range of countries, scope, settings, and analytical approaches. This course is one of many OCW Energy Courses, and it is a core subject in MIT’s underGraduate / Professional Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

Building design strongly influences the quantity of heating, cooling and electricity needed during building operation. Therefore, a correct thermal design is essential to achieve low energy and low carbon buildings, with good indoor air quality.

This course will enable you to understand the basic principles of the energy chain: demand, supply and distribution; and how they relate to design principles for sustainable and energy-efficient buildings.

Second, you will discover what type of heat losses and gains take place in buildings’ operations. You will learn how to estimate these flows using simple meteorological data and construction properties. You will acquire knowledge on how to estimate heat transfer through construction, ventilation, solar radiation or caused by internal sources or heat storage in the construction.

Third, you will learn to make estimates of buildings’ energy needs on an hourly basis by using simple static energy balances: how much energy comes in and out and which air temperature is needed? When is there heating or cooling? How much electricity is needed?

Fourth, you will discover how to extend your estimates to yearly energy demand, which is essential to make sure that a building is energy efficient and to estimate energy savings and energy costs. You will then also be able to determine the size of the needed heating and cooling equipment (which determines the costs of equipment).

Finally, you will learn how to optimize building design and will be able to find out the optimal window size or the optimum insulation thickness for your building. You will know why putting windows on the south façade is not always energy-efficient. You will understand the thermal interactions between building components and be able to make informed decisions on how to increase the energy efficiency of new and existing buildings.

This course is part of the PCP Buildings as Sustainable Energy Systems. In the other courses in this program you can learn how to choose low carbon energy supply, how to create a comfortable indoor environment, and how to control and optimize HVAC systems.

The goal of this course is to provide analytical and hands-on skills on defining and testing power losses in powertrain systems of electric vehicles (EV) and hybrid-electric vehicles (HEV).

The course contains introductory lectures to present power losses and energy efficiency in EV and HEV. Laboratory experiments and computer workshops, the main portion of the course, follow the lectures. The laboratory test modules are built with the use of hardware and tests including ordinary and planetary gear sets, gear power loss test rig, electric motors, two unmanned ground vehicles with individual wheel drives (3-wheeler and 4-wheeler), etc. National Instruments LabVIEW and myRIO are in use for practical laboratory work. Computer workshops facilitate the understanding of HE concepts and operational modes and develop skills in simulating vehicle characteristics.

We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires combining many smaller systems that each perform a function well, and making smart decisions about the sources of power we use. Through five lessons on the topics of heat transfer, circuits, daylighting, electricity from renewable energy sources, and passive solar design, students learn about the science, math and engineering that go into designing energy-efficient components of smart housing that is environmentally friendly. Through numerous design/build/analyze activities, students create a solar water heater, swamp cooler, thermostat, model houses for testing, model greenhouse, and wind and water turbine prototypes. It is best if students are concurrently taking Algebra 1 in order to complete some of the worksheets.

With increasing public awareness of the multiple effects of global environmental change, the terms water, energy, and food crisis have become widely used in scientific and political debates on sustainable development and environmental policy. Although each of these crises has distinct drivers and consequences, providing sustainable supplies of water, energy, and food are deeply interrelated challenges and require a profound understanding of the political, socioeconomic, and cultural factors that have historically shaped these interrelations at a local and global scale.

Energy policy sits at the crossroads of science and policy. And now, energy and climate policy are inextricably linked; the policies we choose have very real consequences for our climate. This intersection of science and policy is chaotic and bustles with activity motivated by various competing (and conflicting) interests and factors. We must understand the motivations driving them and bridge the divides between our reliance on fossil fuels and our need to transition to less carbon-intensive and renewable alternatives. While the science and math behind these problems is often fairly straightforward, the politics and behavioral changes are not. Come stand at this busy intersection with us as we navigate toward progressive climate policy alternatives at all scales of governance!

In this course, you will discover the supply side of buildings’ energy chain.

The first step is to consider how to convert natural resources into the energy needed by buildings: what are the options to create heat, cold and electricity? You will learn about efficiency and use this concept to estimate building’s primary energy use and carbon emissions. This concept is widely used in many national and international policies and building regulations, and is essential to counteract climate change.

You will study the performances of single heating systems like electrical heating, gas, or renewables like biomass, solar boilers and geothermal heat, followed by single cooling systems like evaporative cooling and environmental cold.

We will also examine the systems that concurrently produce heat and cold. Do you know for instance that a heat pump and a cooling machine are identical devices? You will learn about the basic working principles of heat pumps and how to make sure they achieve high performance levels. After this course you will know how an Aquifer Thermal Storage makes smart use of the ground to deliver cold in summer and heat in winter.

Diverse electricity generation methods using turbines (wind, hydro), photovoltaics or hydrogen fuel cells will also be examined. You will learn how cogeneration of heat and power works and why this is important for the rational use of energy resources. You will also know why heat pumps are often combined with boilers or to which extent it is worth to invest in batteries for your solar panels.

By the end of the course you will be able to decide on how to combine energy conversion systems at building level in order to match buildings’ energy demand while keeping costs acceptable, using a minimum of natural resources and producing a minimum of carbon emissions.

This course is part of the program Buildings as Sustainable Energy Systems. In the other courses in this program you can learn how to design buildings with low energy demand, how to create a comfortable indoor environment, and how to control and optimize HVAC systems.
