World total primary energy supply of 155,505 TWh (or 13,371 Mtoe) by fuels in 2012 (IEA, 2014)
World total primary energy supply of 155,505 TWh (or 13,371 Mtoe) by region in 2012 (IEA, 2014)
Primary energy is an energy form found in nature that has not been subjected to any conversion or transformation process. It is energy contained in raw fuels, and other forms of energy received as input to a system. Primary energy can be non-renewable or renewable.
Total Primary Energy Supply (TPES) is a term used to indicate the sum of production and imports subtracting exports and storage changes.
The concept of primary energy is used in energy statistics in the compilation of energy balances, as well as in the field of energetics. In energetics, a primary energy source (PES) refers to the energy forms required by the energy sector to generate the supply of energy carriers used by human society.
Primary energy sources should not be confused with the energy systems (or conversion processes) through which they are converted into energy carriers.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
Food Chains is a 2014 American documentary film about agricultural labor in the United States. It was the Recipient of the 2015 James Beard Foundation Award for Special/Documentary.
In Immokalee, Florida, migrant farmworkers pick fruits and vegetables that are sold to large US food wholesalers. However, their working conditions are shown to be less than favorable. As a result, they form the Coalition of Immokalee Workers (CIW) to raise awareness and improve their circumstances. Specifically, they go on a hunger strike to pressure Publix, a Florida-based food wholesaler, to pay them one penny more per pound of tomato. Meanwhile, the documentary also shows farmworkers in the vineyards of the Napa Valley.
The film was produced by actress and Democratic fundraiser Eva Longoria, Fast Food Nation author Eric Schlosser, and heiress Abigail Disney, among others.
It was presented at the Berlin Film Festival, the Tribeca Film Festival and the Napa Valley Film Festival. Shortly after, Screen Media purchased the distribution rights for North America. A Spanish version, narrated by actor Demián Bichir was released.
In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.
Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

SALE TODAY: Learn Piano on iOS http://bit.ly/PianoAppSale Mahalo biology expert Mary Poffenroth talks about trophic structure, including the hierarchy of the system. The trophic levels of living organisms shows their placement in a food chain, and the order of consumption and energy transfer throughout the environment. Producers, mainly green plants and some types of bacteria, can be found at the bottom of the food chain; they convert solar energy into food consumable by living organisms. Consumers are living organisms that feed on producers and other consumers.http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/biogeography/trophic_levels_and_food_chains.html While plants principally make up the first trophic level, or the producers, organisms that eat plants and meat make up the h...

In this video, we are going to look at a food chain and the different roles within that. So we will discover exactly what each of these words mean: food web, food chain, trophic level, producer, consumer, herbivore, carnivore, omnivore, insectivore, decomposer. A food chain shows the sequence of organisms in a habitat that are dependent on the one before as a source of food. So in a woodland, one food chain would be grass at the bottom, which is eaten by rabbits, which are then eaten by foxes. The arrows represent the energy flow through the chain. A food web shows all of the interconnected food chains in an ecosystem, and are much more complex. In every food chain, there are trophic levels. All organisms in a particular trophic level are the same number of energy transfers away from...

What is an ecosystem? An ecosystem is everything that interacts in a specific area. That includes plants, animals, sun, air, water, and even rocks! In a healthy ecosystem, every part gets what they need - food, water, shelter, light - and all of the parts work together. Unfortunately, an ecosystem can become unbalanced through natural or manmade disturbances. The good news? Ecosystems can recover if we just help them out a little!

All living things need food to have energy which help them to grow and move.A food chain tells how each living thing gets its food and how most of living beings are dependent on each other for their energy requirement.It is also called food web or energy pyramid.A food chain always starts with a producer, which in most of the cases is a plant and it ends with a predator,it is at the top of the food chain. Consumers, scavengers,herbivores and decomposer form important constituents of a food chain.
Autotrophs vs Heterotrophs Producers vs Consumers An autotroph is an organism that can self feed.The word autotroph comes from the Greek autos self and trophe nourishing. Autotrophs are the producers in a food web. Some common examples would include…. Autotrophs produce their energy from the sun in a chemical process called photosynthesis They take Carbon Dioxide plus water and sunlight and produce sugar and oxygen Autotrophs form the base of the energy pyramid. A heterotroph comes from the greek word meaning heteros = another, different and trophe = nutrition Heterotroph get their energy by eating other plants and animals. They use Sugar + oxygen to produce carbon dioxide + water and energy in the form of ATP C6H12O6 + 6 O2 yield 6 CO2 + 6 H2O + Energy This process is ...
This video covers the topics of nutrient cycling and energy flow in marine ecosystems. We discuss the concepts of producers, consumers and decomposers as well as the "10% Rule". This rule states that approximately 10% of the caloric energy content is passed to the next "step" in the food chain. Additionally, about 10% as many organisms exist at each level compared to the level immediately below it. Enjoy and thanks for stopping by! Avoid plagiarism, cite BOGObiology! [BOGObiology].

Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of chemical compounds as its source of energy. Almost all life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae are primarily responsible. Primary production is distinguished as either net or gross, the former accounting for losses to processes such as cellular respiration, the l...

From the CISR video library (http://www.cisr.us) Dr. Kang G. Shin, University of Michigan E-MiLi: Energy-Minimizing Idle Listening in Wireless Networks February 3, 2012 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT The WiFi interface is a primary energy consumer in mobile devices, and idle listening (IL) is the dominant source of energy consumption in WiFi. Most existing protocols, such as 802.11 power-saving mode (PSM), attempt to reduce the time spent in IL by sleep scheduling. However, through an extensive analysis of real-world traffic, we found that more than 60% of energy is consumed in IL, even with PSM enabled. To remedy this problem, we propose E-MiLi (Energy-Minimizing idle Listening), which reduces the power consumption in IL, given that the time spent in IL ...

If you listen to the media and all its experts, we’re in an energy crisis, which includes a mad dash to find new “sources” of fuels that the public has been convinced by “experts,” will run out eventually, if not sooner. Politicians – not “leaders” – justify hostile, aggressive military action, sending young men and women to foreign countries to enforce scarcity-based energy policies, which, is increasingly appearing to be unnecessary, as evidence is mounting that sad shortages themselves are unfounded. Such is the conversation that awaits Talk For Food listeners as Adam visits with Peter Lindemann, PhD., at his home in Spokane, Washington.

Jeffrey Peters explains how the electricity sector plays a crucial role in the global economy. The sector is a major consumer of fossil fuel resources, producer of greenhouse gas emissions, and an important indicator and causal factor for economic development. As such, the sector is a primary target for policy-makers seeking to address these issues. The sector is also experiencing rapid technological change in generation (e.g. renewables), primary inputs (e.g. horizontal drilling and hydraulic fracturing), and end-use efficiency. This work seeks to further our understanding of the role of the electricity sector as part of the dynamic global energy-economy, which requires significant research advances in both database construction and modeling techniques. First, we identify useful engineeri...

Kang G. Shin 2013-2014 Seminar Series January 9, 2014 WiFi interface is known to be a primary energy consumer in mobile devices, and idle listening (IL) is the dominant source of energy consumption in WiFi. Most existing protocols, such as the 802.11 power-saving mode (PSM), attempt to reduce the time spent in IL by sleep scheduling. However, through an extensive analysis of real-world traffic, we found more than 60% of energy is consumed in IL, even with PSM enabled. To remedy this problem, we propose two effective schemes. The first is E-MiLi (Energy-Minimizing idle Listening) that reduces the power consumption in IL, given that the time spent in IL has already been optimized by sleep scheduling. Observing that radio power consumption decreases proportionally to its clock-rate, E-...
What generates almost 11% of the world's electricity with almost no greenhouse gas emissions? It's nuclear power. Since its widespread use began more than 30 years ago, nuclear power has had it critics and advocates. The USA is a large producer of nuclear power with over 100 reactors in 30 states powering almost 20% of nation's electricity. With the recent downturn in the economy causing weakened demand for electricity combined with lower natural gas prices, interest in investments in nuclear power plants slowed but this trend may be changing. In 2012, the US approved plans to construct two new nuclear power plants that are expected to be operational in 2020. Disasters in Three Mile Island (USA, 1979), Chernobyl (Ukraine, 1986), and Fukushima (Japan, 2011) bring to mind safety concer...
