The Science of Energy: Resources and Power Explained

Energy is without doubt the foundation of It is the engine that powers the universe. It’s the engine that powers life and The fuel for evolution of human civilization.

Read the complete description

But energy is not the only thing that matters. and Most non-scientists are unable to understand how it works. Take this example:

Where is the most? of Where does our energy come? and What is the source?
How do energy technologies, both primitive and Cutting-edge technology that generates power
How do we store energy—and Will there be enough to satisfy our future needs?
What are the pros and cons? and Cons behind the forms of Are we currently able to access energy?
How could we harness the potential energy from future sources like earthquakes and supervolcanoes?

These questions are often answered with polemics. and controversy. These are just a few examples of the controversy. and Other questions can be discussed in a scientific, factual perspective. The The truth is that understanding the fundamental science behind energy will help you better see the many issues around energy in 21st century. You need reliable sources that will give you the facts that you need to make educated decisions.

In the 24 lectures of The Science of Energy: Resources and Power ExplainedProfessor, awarded and Michael E. Wysession, expert geophysicist of Washington University, St. Louis provides an objective investigation into the energy resources that power our world. Illustrations, graphs, animations, and in-studio demonstrations are all part of this vibrantly illustrated book. and Other visuals that support scientific research and It is possible to grasp mathematical concepts and understandable, The Science of Energy is a window into the inner workings of the body. of You will be constantly engaged with energy.

Professor Wysession guides you through a large portfolio of renewable and Non-renewable energy sources include coal, oil and natural gas as well as solar, wind, and geothermal. and nuclear fission. You’ll examine how these sources work, the engineering marvels that adapt them to human needs, the economic and environmental consequences of These can be used to your advantage and more. Whatever exciting, rapid changes await us in the coming decades (from food production to public transportation to industrial manufacturing), they’ll most certainly require lots of power. This is why and Many more. This course contains essential information that any educated citizen should know. of the world—whether you’re powering a major city or simply turning on the bathroom light.

Evoking energy from every element

The Science of Energy offers a clear, understandable introduction into the basics of Different energy sources are available, which we take for granted. You should pay the same attention to details. and Accessibility is what makes Professor Wysession one of The Great Courses’ most popular science instructors, his lectures offer a fascinating way to grasp the essentials of the world’s varied energy sources.

Fossil fuels: Coal and Petroleum is responsible for remarkable industrial transformation of Human culture over the past several centuries. A sedimentary rock, coal develops in stages with progressively mOdere carbon—which determines how “dirty” or “clean” Coal is an example of what happens when coal is burned. Petroleum, however, comes from the fossils of Once-living ocean organisms (mostly single-celled plankton), tens of Millions of Years old.
Hydroelectricity: Hydropower is an estimated 1/6 of the world’s total electricity. The It works by the following principle: water that falls through the power station’s power plant will convert its gravitational energy into kinetic energy of The motion of The water is what turns the turbines of A generator.
Nuclear energy: When most people talk about nuclear power, they’re referring to nuclear fission, or the splitting of To release energy, large atoms are required. Nuclear energy can produce almost unlimited power relative to the human time scales. It is made by processing ocean water for uranium (only small amounts). of This is what is required to generate electricity.
Solar energy: Solar energy’s main engineering marvels are photovoltaic solar panels that convert sunlight directly into electricity using semiconducting materials that exhibit a photoelectric effect. While solar energy is constantly renewable, it’s also very geographically dependent; for example, solar power is less effective in a place like Seattle, where it rains a lot.
Wind energy: The power of wind energy has been harnessed by people of Wind for thousands of Years with technology like sailing ships and windmills. The technology to convert wind into a reliable energy source has improved with the advancements in civilizations.and Renewable) power source. Wind turbines can be thought of as plane propellers. The natural wind blows through the rotating rotors. and The engine is then powered by a force.

Find out how energy shapes our lives

“Humans consume an enormous amount of energy,” Professor Wysession: “and countless decisions are made every day—locally, nationally, internationally—to make sure our supply of energy remains available, affordable, and uninterrupted.” Explore the science as you go of energy sources, you’ll also delve into their impact on everything from economic trade agreements to geographical dependency to environmental pollution. The Ziel of these lectures is not to choose a particular side in the energy debate; rather, it’s to illustrate just how far-reaching this science is in our lives. There is much more. of The second half of this course is devoted to probing fascinating questions about energy’s role and Influence in a variety of ways of Natural science subjects and From sociology to nuclear science and meteorology.
