Non-Renewable Energy Resources | GCSE Physics | Doodle Science
 
01:23
Follow me!: https://twitter.com/DoodleSci Doodle Science teaches you high school physics in a less boring way in almost no time! Script: Fossil fuels are non-renewable energy resources; these are coal, oil and natural gas. They were formed from the remains of living organisms millions of years ago and they release heat energy when they are burned. This heat is used to turn water into steam, which is used to turn a turbine, which then drives a generator to generate electricity. There are downsides however, fossil fuels release sulphur dioxide and carbon dioxide which lead to acid rain and an increase in global warming. Another form of non-renewable energy is Nuclear. The main nuclear fuels are uranium and plutonium. The nuclei of these large atoms are split in a process called nuclear fission to release a great deal of heat. The heat energy is again used to boil water. The kinetic energy in the expanding steam spins turbines, which then drive generators to produce electricity. Unlike fossil fuels, nuclear fuels do not produce carbon or sulphur dioxide. However, they do have the risk of a fault where large amounts of radioactive material could be released into the environment such as the disaster of Chernobyl in 1986.

Can We Rely on Wind and Solar Energy?

Is green energy, particularly wind and solar energy, the solution to our climate and energy problems? Or should we be relying on things like natural gas, nuclear energy, and even coal for our energy needs and environmental obligations? Alex Epstein of the Center for Industrial Progress explains.

There’s a lot of sun and a lot of wind. They’re free. They’re clean. No CO2 emissions. So, what’s the problem? Why do solar and wind combined provide less than 2% of the world’s energy? To answer these questions, we need to understand what makes energy, or anything else for that matter, cheap and plentiful. For something to be cheap and plentiful, every part of the process to produce it, including every input that goes into it, must be cheap and plentiful. Yes, the sun is free. Yes, wind is free. But the process of turning sunlight and wind into useable energy on a mass scale is far from free. In fact, compared to the other sources of energy -- fossil fuels, nuclear power, and hydroelectric power, solar and wind power are very expensive. The basic problem is that sunlight and wind as energy sources are both weak (the more technical term is dilute) and unreliable (the more technical term is intermittent). It takes a lot of resources to collect and concentrate them, and even more resources to make them available on-demand. These are called the diluteness problem and the intermittency problem. The diluteness problem is that, unlike coal or oil, the sun and the wind don’t deliver concentrated energy -- which means you need a lot of additional materials to produce a unit of energy. For solar power, such materials can include highly purified silicon, phosphorus, boron, and a dozen other complex compounds like titanium dioxide. All these materials have to be mined, refined and/or manufactured in order to make solar panels. Those industrial processes take a lot of energy. For wind, needed materials include high-performance compounds for turbine blades and the rare-earth metal neodymium for lightweight, specialty magnets, as well as the steel and concrete necessary to build structures -- thousands of them -- as tall as skyscrapers. And as big a problem as diluteness is, it’s nothing compared to the intermittency problem. This isn’t exactly a news flash, but the sun doesn’t shine all the time. And the wind doesn’t blow all the time. The only way for solar and wind to be truly useful would be if we could store them so that they would be available when we needed them. You can store oil in a tank. Where do you store solar or wind energy? No such mass-storage system exists. Which is why, in the entire world, there is not one real or proposed independent, freestanding solar or wind power plant. All of them require backup. And guess what the go-to back-up is: fossil fuel. Here’s what solar and wind electricity look like in Germany, which is the world’s leader in “renewables”. The word erratic leaps to mind. Wind is constantly varying, sometimes disappearing completely. And solar produces little in the winter months when Germany most needs energy.

Nuclear Energy Explained: Risk or Opportunity
 
04:06
Please Read Below For More Information Anything with the word nuclear next to it usually comes with a fair bit of misunderstanding. Hopefully this video demystifies the process of how nuclear fuels are turned into electricity and how we can use them in combination with renewables in order to reduce greenhouse gas emissions and the effects on the climate that come with high levels of them. Of course, there are many things that have been left out this video as nuclear energy, just as with any other source, has many different factors that need to be taken into account when making decisions. In order to fully understand the situation and make decisions, I highly recommend that you do some research of your own on the topic, rather than simply base your opinion on a four-minute YouTube video. It should also be noted that this video has been made from the perspective of the United States in general. Every area on Earth has different natural resources and environments that determine what works best there.

What if I also told you that this energy source was cheap, plentiful, and reliable? Well, there is such a source. You probably know it as fossil fuel. Oil. Natural gas. Coal. But wait? Don’t fossil fuels pollute our environment and make our climate unlivable? That, of course, is what we’re told…and what our children are taught. But let’s look at the data. Here’s a graph you’ve probably never seen: the correlation between use of fossil fuels and access to clean water. More fossil fuel. More clean water. Am I saying the more we that we have used fossil fuel, the cleaner our water has become? Yes, that’s exactly what I’m saying. In the developed world, we take clean water for granted. We turn on a tap and it’s there. But getting it there takes a massive amount of energy. Think of the man-made reservoirs, the purification plants, the network of pipes. In the undeveloped world, it’s a much different story. They lack the energy, so they lack clean water. More fossil fuel. More clean water. The same is true of sanitation. By the use of cheap, plentiful, and reliable energy from fossil fuels, we have made our environment cleaner. Take a look at this graph. More fossil fuel. Better sanitation. Okay, what about air quality? Here’s a graph of the air pollution trends in the United States over the last half century based on data from the Environmental Protection Agency. Note the dramatic downward trend in emissions, even though we use more fossil fuel than ever. How was this achieved? Above all, by using anti-pollution technology powered by…fossil fuel: oil, natural gas and coal. But even without modern pollution control technology, fossil fuel makes our air cleaner. Indoor pollution—caused by burning a fire inside your house, cabin, hut or tent to cook and keep warm—was a deadly global problem until the late 19th century when cheap kerosene, a fossil fuel byproduct, became available in America and Europe. Indoor pollution is still a major issue in the developing world today. The best solution? Fossil fuel. And now we come to the biggest fossil fuel concern of all—global warming. On this very sensitive topic we need to get our terms straight: There is a big difference between mild global warming and catastrophic global warming. We can all agree on that, right? The issue isn’t: does burning fossil fuel have some warming impact? It does. The issue is: is the climate warming dangerously fast? In 1986 NASA climate scientist James Hansen—one of the world’s most prominent critics of the use of fossil fuels—predicted that “if current trends are unchanged,” temperatures would rise 2 to 4 degrees in the first decade of the 2000s. But as you can see from this graph, since 2000 the trend line is essentially flat—little or no warming in the last 15 years. That’s probably why we hear much less talk about “global warming” and much more talk about “climate change.” For the complete script, visit https://www.prageru.com/videos/fossil-fuels-greenest-energy

What is energy for kids | Learn about Energy Sources | Renewable Energy |  الطاقة | エネルギー | zaffron
 
12:32
This video represents a good explanation of What is energy for kids. You will gonna learn about Energy Sources for kids, How we use Energy ( how to save energy ) and a brief understanding about different types of Renewable Energy resources as well as the nonrenewable ones. ► What is energy ? The best definition of energy, that every children should know, is that the Scientists define energy as the ability to do work. Modern civilization is possible because people have learned how to change energy from one form to another and then use it to do work. We use energy to move cars along roads and boats through water, to cook food on stoves, to make ice in freezers, and to light our homes. Energy comes in different forms: Heat (thermal), Light (radiant), Motion (kinetic), Electrical, Chemical, Nuclear energy and Gravitational Energy. People use energy for everything from making a jump shot to sending astronauts into space. There are two types of energy: ( Stored (potential) energy + Working (kinetic) energy ). For example, the food a person eats contains chemical energy, and a person's body stores this energy until he or she uses it as kinetic energy during work or play. Energy sources can be categorized as renewable or nonrenewable When people use electricity in their homes, the electrical power was probably generated by burning coal, by a nuclear reaction, or by a hydroelectric plant on a river, to name just a few sources. Therefore, coal, nuclear, and hydro are called energy sources. When people fill up a gas tank, the source might be petroleum refined from crude oil or ethanol made by growing and processing corn. Energy sources are divided into two groups: 1- Renewable (an energy source that can be easily replenished) 2- Nonrenewable (an energy source that cannot be easily replenished). ► Renewable energy and nonrenewable energy for kids : Renewable and nonrenewable energy sources can be used as primary energy sources to produce useful energy such as heat or used to produce secondary energy sources such as electricity. When people use electricity in their homes, the electrical power was probably generated from burning coal or natural gas, a nuclear reaction, or a hydroelectric plant on a river, to name a few possible energy sources. The gasoline people use to fuel their cars is made from crude oil (nonrenewable energy) and may contain a bio-fuel (renewable energy) like ethanol, which is made from processed corn. ► Moreover, you will gonna learn What is renewable energy for kids ? There are five main renewable energy sources: 1- Solar energy from the sun 2- Geothermal energy from heat inside the earth 3- Wind energy 4- Biomass from plants 5- Hydro power from flowing water ► What is Nonrenewable energy ? Most of the energy consumed in the United States is from nonrenewable energy sources: ( Petroleum products - Hydrocarbon gas liquids - Natural gas - Coal - Nuclear energy ). Crude oil, natural gas, and coal are called fossil fuels because they were formed over millions of years by the action of heat from the earth's core and pressure from rock and soil on the remains (or fossils) of dead plants and creatures like microscopic diatoms. Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal. Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. By watching this video, you will gonna learn how to conserve energy resources ( energy saving ) by understanding how energy conservation mechanism work as well as much knowledge about alternative energy resources. Enjoy watching and have a great time learning about energy sources for children.

√√ Origins of Fossil Fuels | Energy | iitutor
 
12:08
https://www.iitutor.com/ Fossil fuels such as coal, oil and natural gas are non-renewable energy sources that are derived from the remains of fossil plants and animals. Usually, when a plant or animal dies, it decays and is broken down by bacteria mainly into carbon dioxide and water. However the plant and animal remains may be buried beneath sediment before complete decomposition has taken place. The resulting material contains substantial amounts of carbon and hydrogen. Over a period of millions of years these carbon compounds may be converted into fossil fuels by the action of heat and pressure resulting from various geological processes. Essentially fossil fuels are mixtures of hydrocarbons, compounds containing only carbon and hydrogen, with small proportions of other compounds. Fossil fuels have chemical potential energy that is released when they are burned in air. The source of energy locked in these natural resources can ultimately be traced back to the solar energy captured millions of years ago by prehistoric plants. Coal is by far the most abundant fossil fuel. Most of the earth’s coal deposits were formed between 350 and 225 million years ago during the Carboniferous and Permian periods. Coal is produced by the accumulation of plant material in conditions where decomposition by oxidation is negligible. The stagnant waters often associated with swamps, marshes and mangroves are an ideal environment for this process. During the Carboniferous and Permian periods there was an abundance of plant life. Plant debris including leaves, bark and wood accumulated in these ancient swamps and was buried beneath more plant material. Initially the organic matter is converted into peat, a soft, spongy material containing large amounts of water. With increased pressure and temperature, peat is converted into brown coal (lignite) then black coal (bituminous coal) and finally anthracite. The first stage in the formation of coal is biochemical decomposition caused by anaerobic bacteria. This results in the loss of volatile compounds, with an overall increase in the relative carbon content. The second phase, coalification, occurs when the peat is buried and compressed by the deposition of sediments. In coalification the combined effects of temperature and pressure over long periods of time reduce the oxygen content and hydrogen content. This results in increasing carbon content through the sequence peat lignite bituminous coal anthracite. The type of coal produced is dependent on the degree to which the original material has been changed. For example, low grade peat can contain carbon, hydrogen and oxygen in the atomic ratios 1:2:1 while in high grade anthracite the carbon:hydrogen ratio can be as high as 5:2, with virtually no oxygen present. In summary the stages on the formation of different ranks of coal are: 1. Under the influence of pressure and heat, the buried plant material is first converted to peat (55% carbon), which can be used as a fuel source after excavation and drying. 2. Lignite (brown coal, ~67% carbon) is gradually formed from peat as long periods of heat and pressure from overlying sediments chemically alter the remains. 3. Black coal (85% carbon) is formed as compression and heating continue to drive off volatile material. 4. Anthracite coal (93% carbon) is the most metamorphosed form of coal with the lowest percentage of volatile materials (such as water). Coal contains numerous impurities particularly sulfur and sediments such as mud, deposited and buried with plant material. When the coal is burnt, these impurities form pollutants including sulfur dioxide and ash. The pollution associated with the combustion of fossil fuels is discussed later. The sulfur content of Australian coals is fairly low and our coal is therefore in great demand. The Latrobe Valley in Victoria contains some of the world's richest deposits of brown coal and vast deposits of black coal are found in the Sydney Basin, including the Hunter Valley, Lithgow and Wollongong. Petroleum is an organic mixture composed mainly of closely related hydrocarbons. The term petroleum refers to natural gas and crude oil, or mixtures of both, depending on its source. This is the starting point for the petrochemical industry, being the raw materials or ‘feedstocks’ for thousands of essential products. These include synthetic fibres, plastics, and agricultural chemicals, as well as substances used in the manufacture of pharmaceuticals, solvents, paints and detergents. Petroleum is initially formed in plants that convert sunlight into chemical energy by photosynthesis. The remains of plants and animals (organic matter) sink into an environment where it is protected from decomposition by aerobic microbes, such as at the bottom of deep stagnant swamps or on the continental shelf of the ocean.

Renewable energy: can it ever replace fossil fuels, or do other sources have to be explored?
 
06:00
For more information, transcripts and to join the discussion, visit: http://www.commentvisions.com/2008/05/01/topics/alternative-energies/solar-energy/air-conditioning-from-the-sun/ Renewable energy has been both praised and derided as an alternative source of power over the past two decades. To its detractors it is inefficient, unreliable and economically unsound. To its advocates it is free, clean, and unlimited in its potential. With global reliance on dwindling oil reserves an international political priority, attention continues to focus on renewable energy and its applications. This months Comment Visions examines the developments in renewable energy by talking to a man whose work harnesses the power of the sun to produce cooling technology. Dr Ahmet Lokurlu is a Turkish engineer and scientist whose company produces air conditioning systems run by solar power. Generating energy from the sun and turning it into cold air in countries where fuel-hungry air conditioning accounts for more than 40% of totally energy use vividly demonstrates the innovative solutions renewable sources can provide. The 2007 Road Map for Renewable Energy agreed by EU member states set the target of 20% of energy to be provided by renewable sources by 2020, highlighting the importance of the issue within the broader debate over energy challenges. As Dr Lokurlus work demonstrates it is technological development rather than political will, which will set the course for renewable energy in the future. This interview takes a fascinating look at this development and the role innovation can play in changing how we power the planet.

Oil and gas companies are facing major technological disruption
 
14:49
Pressure to reduce carbon emissions is putting the future of fossil fuel giants in jeopardy. Their survival plans involve carbon storage and floating wind farms. Meanwhile, one small German village is showing how large companies aren't always essential. Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 Over 80% of the world's energy needs are provided by coal, oil and gas. Although technologies to extract fossil fuels may have changed over the decades, the core products themselves have never been challenged. Until now. Pressure to reduce carbon emissions is putting the future of fossil fuel giants in jeopardy. Encouraging the growth of alternative methods to generate and distribute power. In just eight years, the value of the world's biggest power companies has halved. Leaving industry giants scrambling to redefine their role in this new energy world. Across the world, old industries are facing disruption on an unprecedented scale. The pressure to adapt has never been greater. Known as the Paris Accord, 195 countries agreed to a legally binding climate deal to reduce carbon emissions. This 5 trillion dollar industry may be facing a seismic shift but that doesn't mean it's ready to ditch the dirty fossil fuels that made it rich. Instead, many companies are banking on new methods to clean up an old process. Norwegian oil and gas giant, Statoil, struck it rich in the North Sea in the late 1960s. Over four decades later, at its Sleipner gas rig, the company is attempting to make fossil fuel production cleaner. Statoil's business still relies on the harmful burning of fossil fuels by its customers but at least the company is trying to reduce its own carbon footprint. It's transformed some of its offshore rigs with technology that enables engineers to separate the carbon dioxide and pump it underground. Statoil's Sleipner gas rig is the world's first offshore carbon capture storage plant. Each year, Statoil stores 1 million tonnes of CO2 making extraction less carbon intensive. They believe that prioritising gas over more harmful fossil fuels will further reduce global warming and keep them relevant for decades to come. Wind and solar are cleaner but depend on subsidies. To take on the consistency of fossil fuels they face a huge challenge - The unpredictable weather. In Bavaria, a tiny village has used those subsidies to take up the challenge. This community believes it's found a way to produce a steady energy supply just from renewable sources, raising the real prospect of a future free from fossil fuels. Norbert and Kristina Bechteler's family farm has been providing the local community with dairy products for over 200 years but they now have a new income from solar energy. Producing your own energy with solar panels isn't revolutionary but in this village, they're combining solar with other renewables in an attempt to achieve the Holy Grail of a steady energy supply. And they're prepared to use anything to do it. The Deputy Mayor has helped drive the village's pioneering efforts to make renewable energy a realistic option. There's one renewable that never disappears as it can be sourced from the decay of virtually any organic matter and it's called biogas. Of the four biogas plants in the village, Farmer Einsiedler runs the largest. Combining these different sources has been so successful the village now generates five times more energy than it needs. But that is just part of the challenge of turning renewables into a credible energy supply. The Disrupters is an original series exploring how major industries – from music and cars to hospitality – are currently being disrupted by the latest wave of digital innovation. As well as enjoying privileged access into the world biggest tech start ups we show how industry giants respond when faced with such tech-driven innovation - do they adapt - or die?

Renewable Energy: It Uses Practically No Water Compared to Fossil Fuels
 
01:18
The Energy Information Administration (EIA) recently highlighted a little-discussed benefit of using renewables like wind and solar to produce electricity: Unlike most power sources, they require “almost no water.” This is remarkable because thermoelectric power generation is the leading use of water in America. (That said, only three percent of power generation's 133 billion gallons a day of water is considered “consumptive use,” as the U.S. Geological Survey says, “meaning it is lost to evaporation or blowdown during generation.”) According to the latest U.S. Geological Survey (USGS) data from 2015, 41 percent of the water used in America is for power generation. The next highest use is irrigation for agriculture, accounting for 37 percent of U.S. water use (and close to two-thirds of that is consumptive). The Union of Concerned Scientists was raising this alarm in 2012 when the nonprofit created an infographic focused on the “energy-water collision,” which “refers to the range of issues that can crop up where our water resources and our power sector interact.” That can include increased competition for dwindling water sources and problems when the water going into or out of power plants is too warm. Why does producing electricity require so much water? As the Department of Energy (DOE) notes: “The main demand for water within a thermoelectric power plant is for condensing steam. Thermoelectric power generation typically converts the energy in a fuel source (fossil, nuclear, or biomass) to steam and then uses the steam to drive a turbine-generator.” This varies somewhat for natural gas, depending on the type of turbine. With many areas of the world, including large parts of America, already dealing with droughts and water shortages — problems expected to be exacerbated by climate change — the water intensity of power sources becomes another factor for local, state, and regional planners to consider. Coal’s Decline Brings Slight Progress The recent topline analysis from the EIA about water use for all energy sources in America is encouraging. Since 2014 the amount of water used to produce energy has been steadily declining. USGS data show this has been the trend since 2005: “The 2015 estimates put total withdrawals at the lowest level since before 1970, following the same overall trend of decreasing total withdrawals observed from 2005 to 2010.” Over a five year period from 2010 to 2015, water use for power generation dropped 18 percent. Much of this drop can be attributed to the decline in coal as a fuel source for electricity generation, as well as power plant closures and new plants implementing more water-efficient technologies. However, while the decline of the coal industry has meant power plants overall are using less water in the U.S., some of the power sources that are replacing coal, namely natural gas, are still highly dependent on water. While the natural gas industry’s claim that methane-rich gas is a cleaner “bridge fuel” to the future — an argument thoroughly debunked when accounting for globe-warming methane leaks in the supply chain — water use is another reason to consider wind and solar power over natural gas. Due to the various technologies used in natural gas power plants, some are more highly dependent on water than others. This variation makes it difficult to quantify just how much water natural gas power generation uses as a sector compared to coal. However, it is safe to say that natural gas power production uses less water than coal in general. Thus, the switch from coal to gas is contributing to the overal decline in water use for power generation, as the USGS and DOE say. As solar and wind become increasingly cost competitive with natural gas for electric power generation — especially in water-constrained areas of the country — they have the added advantage of being a water smart choice.

Renewable Energy Sources, Working of A solar cell, and Biomass fuels
 
05:37
The World currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never run out. After 40 years, the fossil fuels will get exhausted and we will have to use these methods to generate power.
