We have seen some of the issues involved in the conservation and sustainable use of resources like forests, wild-life and water. These can meet our needs perpetually if we were to use them in a sustainable manner. Now we come to yet another important resource – fossil fuels, that is, coal and petroleum, which are important sources of energy for us. Since the industrial revolution, we have been using increasing amounts of energy to meet our basic needs and for the manufacture of a large number of goods upon which our lives depend. These energy needs have been largely met by the reserves of coal and petroleum. The management of these energy sources involves slightly different perspectives from those resources discussed earlier. Coal and petroleum were formed from the degradation of bio-mass millions of years ago and hence these are resources that will be exhausted in the future no matter how carefully we use them. And then we would need to look for alternative sources of energy. Various estimates as to how long these resources will last us exist and one is that at present rates of usage, our known petroleum resources will last us for about forty years and the coal resources will last for another two hundred years.

CBSE class 10 Science - Sources of energy - Petroleum, Coal, Natural Gas are all known as the fossil fuels. Formation of fossil fuels happened millions of years ago. The dead plants and animals got buried into the oceans and rivers, and with the effect of Pressure and Temperature broke down into simpler products and the final product was the fossil fuels. Coal was formed by the remains of the plants whereas the Petroleum was formed by aquatic marine life. Since it takes millions of years in the formation of the fossil fuels hence these are non-renewable sources of energy. Petroleum products are generally used for running the vehicles and the coal is majorly used in the thermal plants to generate electricity.

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.

A explanation of fossil fuels and nuclear energy for AP Environmental Science students.
Views: 517 Lisa Bagley
The flick of a switch, that’s how easy it is to get electricity, right? If you’re one of the lucky ones, then yes. But in 2017 there are still over 1 billion people who do not have access to electricity. In this video we will discuss how electricity is generated and transferred to our homes, for those of us fortunate enough to have it. There are a variety of ways in which electricity is generated or made. How many can you think of? Solar panels, Wind turbines, Biomass, hydroelectric, nuclear and fossil fuels And then there is also geothermal energy, tidal power and wave power as well. Except for burning fossil fuels and nuclear, the rest are renewable sources of energy. Currently about 80% of the world’s energy comes from fossil fuels. First, we’re going to have a look at burning fossil fuels in power stations, to generate energy. And then we’ll look at the national grid - which is relevant for both non-renewable and renewable energies. Fossil fuels in power stations. Most power stations use coal as an energy source, and they work in the following way. Coal is burned in a power station. The heat produced as the coal burns is used to heat water. The water boils and turns into steam. This steam is used to turn the blades of a turbine. A turbine looks like a fan or a wind turbine. The turbine turns a generator. Inside, wires turn within magnets to generate electricity. So that was a fossil fuel power station. These next steps are for energy generated from any source - whether it’s fossil fuels or renewable like wind-powered substations or biomass fuelled. The electricity, whether renewable or not, is passed through transformers and wires, within the national grid, that carries it to our homes. So, what exactly is the National Grid? The National Grid is a system of cables and transformers linking power stations to consumers. Have you ever felt an electrical wire and noticed it gets hot? This is because some energy travelling through the wire is lost as heat. In order to lose as little energy as possible, transformers are used. When the electricity leaves the power station it passes through a step-up transformer. Power station @ 25,000 V A step-up transformer increases the voltage and reduces the current. National grid cables @ 275,000 V Reducing the current makes the transfer of electricity more efficient, as less energy is lost as heat. Before the electricity gets to our homes, the voltage needs to be reduced back down to a safe level. The electricity therefore passes through a step down transformer. Household @ 230 V So, now you know how electricity is generated and sent to our homes, it’s not quite as simple as flicking a switch. Quite a lot of infrastructure is needed.

In which Stan Muller subs for John Green and teaches you about energy and humanity. Today we discuss the ideas put forth by Alfred Crosby in his book, Children of the Sun. Historically, almost all of the energy that humans use has been directly or indirectly generated by the sun, whether that be food energy from plants, wind energy, direct solar energy, or fossil fuels. Stan looks into these different sources, and talks about how humanity will continue to use energy in the future as populations grow and energy resources become more scarce.

America, under President Donald Trump, is securing its “energy independence” with oil and gas. But unlike fossil fuels, renewables will not increase global warming —and China is moving fast. Click here to subscribe to The Economist on YouTube: https://econ.st/2xvTKdy Oil moves the world around and creates powerful countries. Oil is such a vital commodity that it provoked wars throughout the 20th century. The few countries that produce it, try to keep control of it to ensure its riches stay at home. Those who do not have it, strive to get it. In the 1930s Saudi Arabia was one of the poorest countries in the world but the discovery of oil transformed it and Saudi Arabia has amassed $515.6 billion in sovereign wealth funds. It has become the linchpin of a powerful cartel that sometimes rations oil to push up prices. The United States is now the biggest producer of oil and gas owing to its shale revolution. It has tapped abundant reserves through fracking - a technology that uses high-pressure water and sand to fracture rock deep below the ground to extract hydrocarbons. This shale revolution has helped the United States become less dependent on oil imported from Saudi Arabia, Venezuela, Iraq, and other OPEC countries. More oil and gas on global markets has also benefited the world's energy consumers by pushing down costs. Oil still remains the primary fuel, supplying almost 1/3 of the world's energy but its heyday may soon be over, despite growing demand. By 2040 the world's global energy use is set to increase by 30 percent. That energy must be much cleaner if the world wants to prevent catastrophic global warming. In the past coal and gas were less expensive than renewable technology but their costs have come down dramatically. There is now a race among some nations to create more efficient renewable technologies to reduce pollution and be more energy self-sufficient. China is the world's largest consumer of coal and the second largest of oil but it also now leads the world in clean energy. one third of the world's new wind power and solar panels is installed in China, and it sells more electric cars than any other country. The quest for energy self-sufficiency is a big motivation for many countries. China is moving fast, and America under President Donald Trump, is securing its energy independence with oil and gas. But unlike oil and gas renewables will not increase global warming. The long term transition to clean energy will throw up new global challenges. It will create tensions in unstable parts of the Middle East as oil revenue starts to dry up. Another challenge is that wind and sun are intermittent. renewables may require vast shared electricity grids spanning boarders to make them more efficient. To stop global warming the world needs a huge collaboration over our shared energy future. If we fail, wars over scarce resources could be even worse in the 21st century than in the 20th.

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

Full-length film: http://youtu.be/RejAjfRkVuc The world gets through a lot of fossil fuels: • 7,896.4 million metric tons of coal in 2013 (21.6 million metric tons per day, 250 metric tons per second) • 91,330,895 barrels of oil per day in 2013 (168 m3 per second) • 3,347.63 billion m3 of natural gas in 2013 (9.2 km3 per day, 106,082 m3 per second) This film tries to make those numbers physically meaningful – to make the quantities ‘real’; more than ‘just numbers’. All the graphics in the film are based on real quantities. • The coal we use each day would form a pile 236 metres high and 673 metres across. We could fill a volume the size of the UN Secretariat Building with coal every 17 minutes. • At the rate we use oil, we could fill an Olympic swimming pool every 15 seconds. We could fill a volume the size of the UN Secretariat Building with oil every 30 minutes. • The rate at which we use natural gas is equivalent to gas travelling along a pipe with an internal diameter of 60 metres at hurricane speeds (135 km/h / 84 mph). We could fill a volume the size of the UN Secretariat Building with natural gas in under 3 seconds. We use a cubic kilometre of gas every 2 hours 37 minutes and a cubic mile of the stuff every 10 hours 54 minutes. The world’s use of fossil fuels is increasing, not decreasing. Renewable energy will help, but it cannot keep up with the demand for energy. The International Renewable Energy Agency’s most optimistic road-map suggests that renewables will not displace fossil fuels for decades, which is a problem because we are adding carbon dioxide to the atmosphere at an increasing rate.

Happy Thanksgiving! While you’re taking time to be thankful for your friends, family, food, drinks, and other luxuries, perhaps you should take a moment to say thank you to the resources that make this holiday so wonderful: fossil fuels. Watch to learn just how much oil, natural gas, and coal bring to the table during the holiday season (and every other day of the year) VISIT Clear Energy Alliance https://clearenergyalliance.com/ FOLLOW us! Facebook: https://www.facebook.com/ClearEnergyAlliance Twitter: https://twitter.com/clearenergy Instagram: https://www.instagram.com/clearenergyalliance For list of sources and downloadable transcript: https://clearenergyalliance.com/project/thanks-fossil-fuels/ Script: Here’s an unexpected twist on Thanksgiving. While we’re expressing our gratitude for family, friends, food, jobs and other good stuff, let’s include something extremely important that we mostly take for granted. This Thanksgiving let’s acknowledge oil, natural gas, and coal, for without them life would be much shorter, way harder and a lot less fun. Let’s get real here. By historical standards, most of us are living in amazing, exciting future-land. We could spend hours, days really, talking about all the ways that fossil fuels make our lives healthy, productive, comfortable, safe and generally pretty great. But, for the sake of brevity, let’s just take a quick look at look at how we enjoy the Thanksgiving holiday. For starters, very few of us actually have to work on Thanksgiving or the day after, or Saturday and Sunday. It’s a four-day holiday! For about 99.9 percent of human existence, four days of doing nothing but eating, shopping and goofing off would have been unthinkable. The only reason we can take such a long break is that we invented all kinds of machines to do our work for us and all of those machines were manufactured and are powered by fossil fuels. Just imagine all the cars, trucks, trains, planes and ships that were used to bring all that good food to your home, as well as all those important people in your life. Most of the meat, vegetables, breads, beverages, and sweet confections came from hundreds or even thousands of miles away. And don’t forget about the big machines that produced all that food in the first place. Fossil fuels aided by some strong hands did that work. And, by the way, natural gas and oil were used as feedstocks for all the plastics, rubber, lubricants and a multitude of petrochemicals used to package your Thanksgiving feast. Don’t forget about the natural gas range and the electric oven that are used to cook the food and keep it warm. Fossil fuel electricity also powers the lights, the air conditioning, furnace, the TV, phones, and tablets. The water heater is there for everything from meal prep through the clean-up, as is the refrigerator and the dishwasher is pretty handy, too. Ok. I know. You get it. I don’t need to mention that oil, natural gas, and coal were used to bring you the seemingly countless football, basketball and hockey games.... or that lots of fossil fuel will be used when buying up everything under the sun on Black Friday. Although… I guess I just did. Yes... let’s recognize it’s not just fossil fuels that are deserving of our gratitude. Nuclear, hydropower and other renewables deserve some credit as well. But, since fossil fuels pull 80 percent of our energy load, which includes manufacturing all other energy technologies, that’s why fossil fuels should get the bulk of our praise. Of course, be thankful for your family and friends, your faith, your country, your job, and even your favorite beer. But while you’re feeling grateful, give thanks to those hard-working people that produced the fossil fuels that work so hard for you on Thanksgiving and every other day of the year. Happy Thanksgiving. For the Clear Energy Alliance, I’m Mark Mathis. Power On.

1. A major advantage of fossil fuels is their capacity to generate huge amounts of electricity in just a single location. 2. Fossil fuels provide a large amount of concentrated energy for a relatively low cost. 3. Safe to transport: Because fossil fuels are safe and stable, they can be transported easily and efficiently over long distances. 4. Easier to Find: Fossil fuels are actually very easy to find. They occur all over the world, usually in very rich veins deep inside the earth, which means that, once we have committed to getting coal or gas out of the ground or out from under the sea, we are guaranteed to get a lot of resources from that particular area. 5. When coal is used in power plants, they are very cost effective. 6. Oil can be transported through the use of pipes, allowing it to be transported relatively easily. 7. Massive economic benefits 8. Generate Thousands of Jobs: Fossil fuels generate hundreds of thousands of jobs every year. 9. Power stations that make use of fossil fuel can be constructed in almost any location. 10. High calorific value 11. Useful by product

You might be wondering what a high school student can do to help address climate change. In his fascinating talk on his experimental research into energy independence, Dhruvik Parikh offers unique theories in the form of agricultural waste and “close-looped” systems where the waste of production can be used to fuel the next round of production creating local systems that are self-sustaining. Dhruvik also addresses concepts for community access to clean water and energy storage where whole communities work to develop their own collective renewable energy system. By examining the environmental and economic considerations of harnessing energies already available, Dhruhvik sees a future where cities can be self-sustaining and communities can thrive.

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.

Fossil fuel: fuels which are obtained from the remains of plants and animals are called fossil fuels. Ex- coal and petroleum. Fossil fuels are non-renewable sources of energy so we need to conserve them. Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years. Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Other commonly used derivatives include kerosene and propane. Fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. Methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates. Harmful effects of fossil fuels The oxides of carbon, nitrogen and sulphur that are released on burning fossils fuels acidic oxides. These lead to acid rain which affects our water and soil resources. The problem air pollution and the green house effect of gases like carbon dioxide. The pollution caused by burning fossil fuels can be reduced by increasing the efficiency of the combustion process and using various techniques to reduce the escape of harmful gases and ashes into the surroundings

The difference between renewable and non-renewable resources can be done on the basis of their usage life, carbon emission, quantity available, maintenance cost, environment friendly nature, land area required for installation and much more. The energy resources which cannot be exhausted and can be used again and again are called renewable energy resources. For example solar energy, wind energy, tidal energy and hydroelectric etc. The energy resources which can be exhausted one day and cannot be used repeatedly are called non-renewable energy resources. The example of non-renewable energy resources are coal, petroleum, natural gases etc. 1. The renewable energy resources can be depleted and used again and again. But the non-renewable resources are limited in number and can be depleted one day. 2. The carbon emission in renewable energy resources are very low and prevent global warming. In non renewable resources the carbon emission is large and contributes in global warming. 3.The renewable resources are cheaper and present in unlimited quantity but the non- renewable resources are costlier and present in limited quantity. 4. The life of renewable resources is infinite. In case of non-renewable resources the life is finite. 5. The maintenance cost for the power plant of renewable energy resources is low but it is high in the case of non-renewable energy resources. 6. Solar energy, wind energy, tidal energy and geothermal energy are called as renewable resources. Coal petroleum, natural gas, are called non-renewable resources. The wait is finally over.

EXPERTS POINT TO PROBLEMS. HAS ANYONE OFFERED A PLAN TO FIX THE PROBLEMS? THE FOUNDATION HAS A PLAN. We empower the consumer to create change. We introduce an economic movement with environmental benefits. We compete with fossil fuel resources to stop the profits that cause unsafe practices, toxic products, and environmental carnage. We rebuild the middle class, alleviate poverty, and promote global trade without sacrificing the environment or public. We can do all of this by changing the resources we manufacture products with and by making you aware of the power of protest through purchase to ensure big business supports it. We all can simply boycott fossil fuel products. However, we must first build cost effective alternatives to compete with fossil fuels, or we will be stuck in that area that where passion isn't enough to compete with profit. Few will give up their toxic iphones or plastic bottles for change without an affordable substitute.

Renewable Coal, Oil and Natural Gas? Does it matter? Well, Yeah. All three were formed many hundreds of millions of years ago before the time of the dinosaurs - hence the name fossil fuels. The age they were formed is called the Carboniferous Period. Abiotic Theory. There is an alternative theory about the formation of oil and gas deposits that could change estimates of potential future oil reserves. According to this theory, oil is not a fossil fuel at all, but was formed deep in the Earth's crust from inorganic materials. The abiogenic origin of petroleum deposits would explain some phenomena that are not currently understood, such as why petroleum deposits almost always contain biologically inert helium. Abiogenic petroleum origin is a term used to describe a number of different hypotheses which propose that petroleum and natural gas are formed by inorganic means rather than by the decomposition of organisms.
