This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

Follow me!: https://twitter.com/DoodleSci Doodle Science teaches you high school physics in a less boring way in almost no time! Script: Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate. The wind is produced as a result of giant convection currents in the Earth's atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there's no electricity. Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.

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.

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

A explanation of fossil fuels and nuclear energy for AP Environmental Science students.
Views: 365 Lisa Bagley
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.

Importance of Renewable Energy -Types of Renewable Energy http://bit.ly/2Ng8DIl Importance of Renewable Energy and Types of Renewable Energy RENEWABLE ENERGY http://bit.ly/2Ng8DIl Renewable energies are sources of clean energy, inexhaustible and increasingly competitive. They differ from fossil fuels mainly in their diversity, abundance and potential for use anywhere on the planet, but above all because they do not produce greenhouse gases, which cause climate change, or pollutant emissions. Their costs are also declining and at a sustainable pace, while the overall trend of the cost of fossil fuels goes in the opposite direction despite their current volatility. The growth in clean energy is unstoppable, as reflected in the statistics produced in 2015 by the International Energy Agency (AIE): they accounted for almost half of all the new generation capacity installed in 2014, when they were the second largest source of electricity largest in the world, behind coal. According to the IEA, global electricity demand will have increased by 70% by 2040, its share of final energy use will increase from 18 to 24% during the same period, driven mainly by the emerging economies of India, China, Africa and Middle East. and Southeast Asia. Why do we need to use renewable energy? http://bit.ly/2Ng8DIl Since then, the shares of U.S. energy consumption from biofuels, solar, and wind energy have increased. ... Renewable energy plays an important role in reducing greenhouse gas emissions. Using renewable energy can reduce the use of fossil fuels, which are major sources of U.S. carbon dioxide emissions. What are the advantages of renewable energy? http://bit.ly/2Ng8DIl One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation. Why is it better to use renewable energy? A wealth of alternative energy sources, from wind and solar energy to hydroelectricity and biomass fuel offer a way to power homes, vehicles or businesses without using fossil fuels. That means renewable energy sources can help reduce the amount of greenhouse gas emissions we put into the air. Why do we need energy? http://bit.ly/2Ng8DIl Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body's most important nutrient, helps facilitate the chemical reactions that produce energy from food Why solar energy is important? Solar Is Clean and Safe. Solar is a safe alternative which can replace current fossil fuels like coal and gas for generation of electricity that produce air, water, and land pollution. ... Use of solar energy will eliminate these unsafe, unclean consequences from using conventional fossil fuels. Why is energy so important? http://bit.ly/2Ng8DIl Energy, defined as the capacity for work. It is almost the cause of so many things going on around us. When we eat, our bodies stored energy through the food and this energy turn into for allowing us to do action in any business. ... Energy is very important for world also our daily life Why is it important to save energy? It's a no-brainer: When we use less energy, we save precious natural resources and cut down on pollution. ... So, energy efficiency helps us keep more resources on the earth longer. Avoiding pollution: From power plants to cars, consuming energy can produce emissions that harm our environment. http://bit.ly/2Ng8DIl Importance of Renewable Energy - https://youtu.be/gN_-4Kp55s8

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.

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.

The world is driven by fossil fuels like oil and gas. This has some negative repercussions: Rising energy prices due to decreasing deposits, dependence on unstable oil and gas producing regimes and global warming. It becomes clear, that a revolution in the way how we produce and use energy is necessary. Central to this energy transition are new technologies, which produce energy from renewable sources such as wind or sun. With Germany as an example, this documentary video shows what renewable energies are and how they work as well as what the concept of energy transition means.

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. Student at Henry M. Jackson High School, Mill Creek, Washington. Participant in a variety of clubs including the Technology Student Association and MIT Launch Club. Co-founded startup, Travalot, at the prestigious MIT Launch startup incubator. Managed strategy and operations for the company. Interested in finding solutions to the energy storage conundrum. Developed a novel method of biodiesel production using winery waste and engineered a membrane for redox flow batteries for superior conductivity. Is passionate about "distributed energy" and the equitable rollout of new technologies in developing countries. Well versed in Java and Python.

Activate the subtitles in the player window, interviews are in French! For thousands of years biomass (organic matter) was the primary source of energy. Since the industrial revolution, the combustion of fossil fuels, accounting for 87% of today’s global energy package, has replaced biomass as the primary source. Yet issues surrounding energy and food production and sustainable development engender new perspectives on the production of bio-fuels, especially from by-products of agro-industry and forestry. Biomass, now supporting 10% of world energy consumption, could increase to provide 25% of global energy needs. This film combines figures, schematics, and interviews with professionals in the field (e.g. economist, farmer, mechanic, researcher, aircraft manufacturer...). The potential for biomass is evident, but its usage must be rational, optimized and adapted to local environments. A film by Gérard Goma (scientific advisor) and Mathias Fyferling

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.

Green Biologics are a renewable chemicals company who are not only changing the face of renewable chemicals, but are changing the world while they are at it. Dr Liz Jenkinson is one of the lead researchers at the company, and it is her work that is providing the answer to the question: is there an alternative to fossil fuels? Her work proves that the answer is yes, and that it only relies on three key components – bacteria, genetic engineering and sugar.

We generally assume that alternative energy production offsets fossil fuel use. But does it? http://GreenIllusions.org Subsidizing energy production expands energy supplies. We like that because it leads to lower energy costs. But, demand for energy subsequently increases. So we come right back to where we started with high demand and so-called insufficient supply. Well then we need more energy subsidies... And the cycle continues. About the book Green Illusions: We don't have an energy crisis. We have a consumption crisis. And this book, which takes aim at cherished assumptions regarding energy, offers refreshingly straight talk about what's wrong with the way we think and talk about the problem. Though we generally believe we can solve environmental problems with more energy—more solar cells, wind turbines, and biofuels—alternative technologies come with their own side effects and limitations. How, for instance, do solar cells cause harm? Why can't engineers solve wind power's biggest obstacle? Why won't contraception solve the problem of overpopulation lying at the heart of our concerns about energy, and what will? This practical, environmentally informed, and lucid book persuasively argues for a change of perspective. If consumption is the problem, as Ozzie Zehner suggests, then we need to shift our focus from suspect alternative energies to improving social and political fundamentals: walkable communities, improved consumption, enlightened governance, and, most notably, women's rights. The dozens of first steps he offers are surprisingly straightforward. For instance, he introduces a simple sticker that promises a greater impact than all of the nation's solar cells. He uncovers why carbon taxes won't solve our energy challenges (and presents two taxes that could). Finally, he explores how future environmentalists will focus on similarly fresh alternatives that are affordable, clean, and can actually improve our well-being.

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.

Hazards of Renewable Energy The facts are in and yes Renewable Energy and technologies are lowering the carbon footprint slowly over time. But let’s make it clear that All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. However, renewable sources such as wind, solar, geothermal, biomass, and hydropower also have environmental impacts, some of which are significant. For instance, the amount of land they take up, the sounds and vibrations are big complaint by nearby homeowners. There are also greenhouse gases caused by the manufacturing of these renewable manufactures of solar and wind farms. Not to mention the human dangers associated with going 100% renwable energy. Wind Turbines have the highest accident rate in the work place. The transportation of the giant Blades for these Wind Mills are challenging to transport. The manufacturing isn’t that safe either, and they seem to attract lightening which casuse severe damage to the turbine engines.
