Switch (2012 film)

Switch (2012 film) is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Switch (2012 film) rather than just read about it. In short: Switch is a documentary film on global energy directed by Harry Lynch, produced and distributed by Arcos Films, and featuring Scott W. Tinker, a geologist and energy researcher who runs the Bureau of Economic Geology, a 200-person research unit of The University of Texas at Austin. and is a professor at the Jackson School of Geosciences.

Key takeaways

  • Switch (2012 film) belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Switch (2012 film) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Switch (2012 film) from memory before moving on to harder problems.

Reference excerpt

Switch is a documentary film on global energy directed by Harry Lynch, produced and distributed by Arcos Films, and featuring Scott W. Tinker, a geologist and energy researcher who runs the Bureau of Economic Geology, a 200-person research unit of The University of Texas at Austin. and is a professor at the Jackson School of Geosciences. The film is part of a larger energy education and efficiency project, which also includes the Switch Energy Project website, with additional video content and educational programs. The website includes interviews with energy policy analysts such as Ernie Moniz, former under secretary of energy, Steven E. Koonin, deputy executive director of the International Energy Agency, Richard Jones, and physicist Richard A. Muller. The film aims to be a nonpartisan, scientifically based exploration of the energy transition from the traditional energies of coal and oil to future energies. It has been accepted by many environmental groups, government agencies, fossil and renewable energy companies and academic institutions. Switch premiered at the 2012 Environmental Film Festival in Washington DC to positive reviews, then played at 12 other international festivals, most of them environmentally focused, and at 6 international geology conferences, before opening in theaters in New York in September 2012.

Synopsis Switch begins in Norway, where Dr. Tinker explores an electricity system built on renewable hydropower. There, he asks the central question of the film: what will the energy transition look like for the rest of us. Over the following 90 minutes, he travels the world to find out. His first step is to calculate how much energy the average person uses in a year, including all the energy embodied in the food and products we consume, the roads and public buildings we share. He uses that figure to measure and compare each energy type he visits. Tinker starts with the big conventional energies, coal and oil, trying to determine their futures. Can coal be clean? Will we keep using it? Will oil price keep rising? Will we run out of it? He then examines the energies that may replace them. For oil, those are biofuels, natural gas and electricity. For coal, they are geothermal, solar, wind, natural gas and nuclear. With each type, he visits various facilities, talks to the experts in the Department of Energy, universities, and gives an analysis of each resource’s major pros and cons. After his journey, he assembles his findings to map out the likely energy future. While coal and oil will continue to play a large role especially in developing countries, a global transition to where their alternatives become dominant will happen in about 50 years. Renewables see by far the largest growth rate, while natural gas makes up the largest portion of the replacement, with nuclear approximately equal in share to renewables. Tinker ends by emphasizing that energy efficiency, including personal energy conservation, will play a vital and growing role in a successful energy future: “The most important thing is to change the way we think about energy, so we can change the way we use it.”

Reviews "Switch is refreshingly free of hot air. It’s almost shocking in the way it sidesteps the kind of issue advocacy made commonplace by filmmakers Michael Moore, Davis Guggenheim and the like. Lynch’s film tries (and largely succeeds) in taking a scrupulously neutral tack between extremes." - The Washington Post "Sidestepping the usual eco-docu strategy, Switch takes a far less hysterical route. Lynch’s method gives a rational evaluation of where the world is heading. It’s considerably more honest, and manages to be quite effective. Tech credits are tops, particularly the seamless editing and the often beautiful photography.” - Variety "Tinker comes across as affable, reasonable, and unfailingly curious. His interview subjects are technicians, business executives, scientists, government officials. It insures a tone of dispassionate seriousness and good will." - Boston Globe "Tinker takes us along for this beautifully shot ride, excellent in its details, and mixes a kind of gee-whiz wonderment at the way energy is produced with pithy, on-the-mark observations about the realities of those sources. He foresees the increasing use of renewables, natural gas and nuclear power in the US. But he also offers a sobering forecast of why we’re unlikely to shake coal and oil for a long time." - Austin American-Statesman "There's no one solution to solving the energy crisis, but that's where Switch provides a valuable resource. In addition to the film, the Switch Energy Project also provides a deep video archive of the many interviews Dr. Tinker captured and used throughout the film." - TreeHugger

Education As of 2013, Switch is currently screening at university campuses as part of an energy awareness and efficiency program sponsored by the Geological Society of America. The website mentions an upcoming primary education program being co-developed with the American Geosciences Institute.

Worked examples

Example 1 — a first encounter with Switch (2012 film)

Start with the simplest possible case. Write down what Switch (2012 film) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Switch (2012 film) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Switch (2012 film) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Switch (2012 film)

In research
Switch (2012 film) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Switch (2012 film) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Switch (2012 film) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2012 American films, 2012 films, American documentary films, so understanding it makes those chapters shorter.
In everyday life
Look for Switch (2012 film) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
