Can We Rely on Wind and Solar Energy?
 
04:24
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.

Renewable energy from offshore wind farms - Infineon Technologies
 
07:33
http://www.infineon.com/energy-efficiency - Energy means life: It heats houses, powers cars and lights megacities. The global appetite for energy is voracious, while resources are dwindling. One third of the energy consumed worldwide is electricity and the trend is rising. The name of the key energy source of the future is energy efficiency. Optimal electricity use is achieved by harnessing smart semiconductor technology: Innovative chip solutions fine-tune cars, industrial plants, consumer and household electronics to use less energy. And smart meters permit evaluation of every kilowatt hour with to-the-minute accuracy, helping to save electricity. The future of Wind Energy can be identified in offshore areas worldwide. Looking just at the North- and Baltic Sea, around 30 offshore wind farms are planned to come up in the next few years. Tomorrow's electricity grids will be smart The electricity grids of the future will feed themselves locally from wind, sun and water. However peaks and troughs are inevitable. Smart grids will control the power supply and demand thus ensuring a reliable flow of current. Employing Infineon's innovative semiconductor solutions means that electricity comes from the socket with low losses. Our power electronics transmit energy from the power station to the consumer efficiently, over thousands of kilometers.

Each passing day, we come up with alternative ingenious renewable energy solutions that are cleaner, more efficient, sustainable, and renewable. Here are some ingenious alternatives! Subscribe for more! ► https://goo.gl/pgcoq1 ◄ Stay updated ► https://goo.gl/JyGcTt https://goo.gl/5c8dzr ◄ For copyright queries or general inquiries please get in touch: [email protected] Be Amazed at these top 10 renewable energy solutions! Algae - Though a green eyesore on the water, algae’s potential was first suggested in 1942 as a source of food and fuel. It wasn’t taken seriously till the 1970s, however, when oil prices surged due to the oil embargo, forcing the US government to look into it. Carnegie Wave Energy - Australians have taken their love of surfing above the waves to another level – harnessing the power of waves below the surface thanks to Carnegie’s CETO technology. Tidal Power - A few other ways of harnessing tidal power include using Horizontal Axis Tidal Turbines . Osmotic Power - Osmotic power is generated when salt water meets fresh water – something that happens in nature when rivers flow to the sea. Solar and Wind Power - Why use solar panels when you have to deal with the night, bad weather, and cloudy days? By putting a solar array in space, we can have unlimited access to solar power which can be transmitted to homes in much the same way as cable channels. Human Power - While pedal power has been around for a while, foot power is new thanks to Pavegen – a company that harnesses the power of footsteps. Lava Geothermal Generators - Iceland already uses geothermal energy from its many steam vents, but in 2014, it accidentally dug directly into a magma chamber. Turbulent Micro Hydro Power Plant - Turbulent came up with a simple whirlpool turbine that can power dozens of homes using the power of rivers and canals without harming fish. Batteries - The problem with solar and wind power lies in the fact that these sources of energy tend to be generated when they aren't always needed. Windmills - Texas prides itself on big things, but researchers at the University of Texas Arlington bucked that trend with micro-windmills .

Future Alternative / Renewable Energy : Solar, Wind, Biomass, Ocean,  Hydro Power ... (Top Truths)
 
04:27
Future Alternative /Renewable Energy : Solar, Wind, Biomass, Ocean, Hydro Power ... (Top Truths) Future of Electric Power - Renewable Clean Energy - Go Green - Alternative Energy Perhaps one of the most pressing issues we humans must all face in the coming years is how to continue to power our lives whilst our limited resources like coal and oil are eventually exhausted. Fortunately, there have been many developments in the field of renewable energy. The most commonly known forms are of course solar and wind energy, but there are many more possible alternatives, too. Collectively, these will shape The Future Of Electric Power. Fuel Cells Fuel cells produce energy through chemical reactions that combine hydrogen with oxygen. When a hydrogen-rich fuel such as natural gas or biogas flows through a fuel cell and reacts with oxygen, it produces electricity, heat and water. Fuel cells, which emit about half of the emission of a fossil fuel power plant, aren’t cheap enough to become a primary power source, but they are being used by a growing number of companies to provide backup power as well as reduce their carbon footprints. Fuel cells are also making their way into the automotive world to create zero-emissions cars. Geothermal Power Humans have been harnessing the power of super-hot steams underneath the Earth’s surface for as long as records show, but the first geothermal power generator wasn’t built until 1904 in Italy. The first geothermal power plant in the United States came online in 1921 to help run a hot spring resort at The Geysers in northern California. The Geysers, which covers almost 20,000 acres, is the world’s largest geothermal field and is now home to nearly a dozen power plants. Geothermal power makes up just 3% of the USA’s renewable energy supply. Ocean Power The rhythmic and powerful movements of the ocean current and waves can drive electric generators to produce a steady stream of vast amounts of power, which would then be transported to land via cables. This presents an extremely hopeful promise for clean energy. The catch? Developing the equipment that would effectively capture all of that mechanical energy whilst withstanding the corrosive salt water and other natural elements out in the ocean is proving to be highly challenging. There are currently no commercial ocean energy power plants in the US, though a number of research and pilot projects have taken place in California, Oregon, Hawaii and New Jersey. Those projects test equipment designs, which resemble everything from giant jellyfish to a snake, to see how well they perform in the rough environment and whether they could efficiently produce enough energy to justify the steep costs of installing and operating them. Hydropower The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. However, hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine. Hydropower is one of the oldest sources of electricity in human history and is used by every state in the USA. The world’s first commercial hydropower plant came online on the Fox River of Appleton, Wisconsin, in 1882. Hydropower is also the largest source of renewable energy, accounting for just over 6% of US electricity generation and 92% of renewable energy production. Washington state, in particular, relies on hydropower for more than 70% of its electricity. Biomass Electricity produced by plants or animal by-products is known as biomass energy. Biomass power plants directly burn feedstock such as wood chips, agricultural waste, some types of garbage or animal manure in order to produce electricity. It’s also possible to convert the materials into combustible gases and then burn them to generate power. Biomass power accounts for 12% of the USA’s renewable energy supply. Biomass is used in almost every nation in the world for electricity generation. Sweden, for example, relies on biomass for 30% of its energy. https://www.facebook.com/toptruths/ https://www.toptruths.com https://www.advexon.tv LIKE / SHARE / SUBSCRIBE Playlists: TOP Educational: http://bit.ly/TTEducational TOP 10: http://bit.ly/TOPTruthsTop10 TOP Cotroversial: http://bit.ly/TOPTruthsControversial TOP Science & Tech: http://bit.ly/TOPTruthsScTech

34. Renewable Energy
 
48:03
The Atmosphere, the Ocean and Environmental Change (GG 140) Renewable energy sources are discussed. These include wind energy, solar energy, biomass energy and geothermal energy. Energy from wind is acquired through the use of large wind turbines. These turbines ideally need to be located in areas where there is strong wind and low atmospheric turbulence. Solar power is collected using both photovoltaic solar cells and concentrated solar power. Energy from biomass can be produced in two ways: burning biomass to generate electricity or fermentation to produce fuel ethanol. Geothermal energy is produced by pumping water below the earth's surface into areas of hot rocks which heats the water and creates steam. This steam is then run through a turbine to produce power. 00:00 - Chapter 1. Renewable Energy Sources 02:20 - Chapter 2. Wind Energy 35:19 - Chapter 3. Solar Power 42:18 - Chapter 4.

Breakthrough in renewable energy - VPRO documentary - 2016
 
46:11
It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy. In countries like Brazil, Australia, Chile and parts of the United States people consider renewable energy because of financial reasons. The price of solar and wind energy will continue to drop and in more countries renewable energy will occur. A surprising newcomer on the market is Morocco, where the government expects that in 2020 more than 40 percent of the energy could come from solar energy.

Wind and solar energy is growing in India
 
06:54
Today coal accounts for approximately 57% of India's total energy consumption and is responsible for 67% of India's increased carbon emissions. But renewable energy alternatives are growing rapidly throughout the country. Solar technology, wind power and other natural resources sources have been utilised to produce electricity, bringing power to those who would otherwise be without. The abundance of natural resources in India uncover its potential as a world leader in renewable energy and prove that increased coal exports from Australia are unjustified and harmful.

[BBC Technology Documentary] Renewable Energy - NEW  Science Documentary HD
 
40:15
[BBC Technology Documentary] Renewable Energy - NEW Science Documentary HD Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.[2] Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.[3] Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. Both, modern renewables, such as hydro, wind, solar and biofuels, as well as traditional biomass, contributed in about equal parts to the global energy supply. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.[4] Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.[5] In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power.[6] At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.[7] While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development.[8] United Nations' Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity ========================================wbr= Watch more :http://goo.gl/MccsMM *** *** *** *** ========================================wbr= Thanks for Watching Please Like and Subscribe to watch more videos

GREEN ENERGY IN CHINA
 
04:48
On average, Chinese people use a third of the energy used by a person in a developed nation, yet China is one of the world’s largest emitters of greenhouse gases. So how will China fulfil the responsibilities agreed in the UN Paris Agreement (CMA1)? Let’s take a look at how China plans to reduce its energy consumption, introduce new technologies and the different energy sources used - hydropower, wind power, solar power, geothermal energy and nuclear power. China’s goal is that 20% of its energy will come from non-fossil fuel energy by 2030. So where will it come from? China not only possesses the largest installed hydropower capacity in the world, but also the most advanced hydropower technology. China’s wind power industry is the fastest growing in the world with two wind turbines installed per hour in 2015. China’s biggest plant has more than 3,500 turbines. But next, China needs to improve the grid to make sure it can use all the wind power that it generates. China can make more solar energy than anywhere else on earth and also supports the development of solar power worldwide with advanced technology and equipment. In 2020, the country’s solar panel installation capacity will reach 110 million kilowatts – which can provide electricity for 80 million people. It is particularly valuable in rural provinces, where more and more people are turning to home solar systems for energy. Turning agricultural residue into pellets has kick-started a national biogas industry in China. 120 kilometres south of Beijing, China has developed its first smoke-free city - Xiong County, which has become a model for other parts of China. 95% of its heating comes from geothermal sources. As China has one sixth of the world’s geothermal resources, this resource will help to increase China’s use of non-fossil fuel energy from 12% to 15%. Nuclear power currently accounts for 3% of China’s total power generation. China’s nuclear power units in operation have never had accidents at or above Level 2 on the International Nuclear Accident Classification scale. But China’s plans to reduce carbon emissions don’t just focus on clean energy – it plans to reduce its energy consumption and introduce new technology and approaches. China has become the world’s largest electric and hybrid vehicle market and is subsidizing the industry to make it more attractive for manufacturers and consumers. And in 2017, China introduced the world’s largest carbon-trading market encouraging companies to curb emissions.

Renewable Energy Resources: Part 1 | GCSE Physics | Doodle Science
 
01:48
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.

Examples of Renewable Resources
 
02:07
Visit us/get in touch at: http://wastersblog.com/1653/examples-of-renewable-resources/ We provide Examples of Renewable Resources: A renewable resource is one that replaces itself normally at a rate equal to or higher than human usage. The term normally refers to renewable energies, which are self-sustaining in time. There are 5 primary kinds of renewable resources, solar, wind, hydropower, geothermal and biomass. Many countries today are increasing their use of renewable energies to change fossil fuels, such as coal and petroleum, which take thousands and occasionally millions of years to change themselves, making them non-renewable resources. Examples of non-renewable resources are fossil fuels, like coal, oil, natural gas and soil, rocks, minerals. As soon as they have been gotten rid of from a mine or removed it takes a very long time indeed for them to re-form. We have actually counted on fossil fuels for our energy requires because, traditionally, these fuels have actually been reasonably inexpensive, and rewarding for designers. With increasing fuel costs, issues about ecological effect and growing political concerns about oil providers, renewable energy is acquiring in importance. Renewable resources are natural sources that can not be diminished. Examples consist of solar, wind, hydroelectric, biomass and geothermal. Fossil fuels like coal, oil and even clean-burning gas do not exist in unrestricted supply. One day they will be gone. In additional to unending availability, renewable resources create less environmental impact, specifically pollution. Generally speaking renewable resources can be categorized as natural renewable resources and non-organic renewable resources. Plant and animal species are the examples of natural renewable resources whereas gases like oxygen and water are the examples of non-organic renewable resources. Birds or animals getting extinct have now become a regular function. Although some species have actually disappeared from the earth's surface due to natural tragedies, most of them have actually become extinct due to excessive hunting and poaching. Examples of renewable resources are fresh water, fish, and soil. Non-renewable resources such as oil and minerals are irreplaceable, and they do not effectively regrow once they are consumed. Renewable energy describes power created by a renewable source. When the energy is generated, the resource is not exhausted or consumed. They are naturally replenished, and can either be managed so that they last permanently, or their supply is so enormous human beings can never ever meaningfully deplete them. Unlike fossil fuels, renewable energy sources do not release carbon dioxide as a byproduct into the atmosphere. As the quantity of nonrenewable fuel source resources in the world lowers, it is ending up being increasingly essential to discover and make use of alternative fuels. In the US, Alternative Energy is made use of and in general it implies the like renewable, implies any thing besides deriving energy through Fossil Fuel combustion. Alternative energy is likewise a natural deposit ends up being a renewable resource when it is replaced by natural processes at a rate which is quicker than its consumption rate by human beings. Solar radiation, tides, winds and hydroelectricity are the sources which are of lasting accessibility. Renewable resources may include mean products like wood, paper, and leather, if their harvesting is carried out in a sustainable way. So, to summarize, we will certainly just say that renewable resource is a natural resource that can replaced with biological or other natural processes and renewed after a long time. They are part of natural environment however they are threatened by commercial developments and development. Solar radiation, biomass, tides, geothermal, and winds are examples of renewable resources.

Grid Integration of Intermittent Renewable Energy Resources
 
51:39
Speaker/Performer: Solomon Abebe Asfaw, UC Berkeley Sponsors: CITRIS (Ctr for Info Technology Research in the Interest of Society), i4Energy Center Energy storages are expected to play a significant role in increasing grid penetration of intermittent renewable resources. In this presentation, I will show that -, based on various hourly simulations,- storage design and dispatch plays a significant role in our ability to transition to a grid that can accommodate very large intermittent renewable systems. First, I will describe the result of an hourly simulation performed for an island Israeli grid. This will be followed by a brief discussion of the case of an interconnected grid using an hourly load data and the corresponding simulated wind and solar output for the state of California. This study shows that to design such a grid, we will be required to consider a new operational policy. In this talk, I will also discuss other complications related to designing such a power grid. ---------- Solomon Abebe Asfaw received his undergraduate degree in Physics from Bahir Dar University, Bahir Dar, Ethiopia; an M.Sc. degree in Physics from the Norwegian University of Science and Technology, Trondheim, Norway; a second M.Sc. and PhD degree specializing in energy system modeling from Ben-Gurion University of the Negev, Sede Boqer, Israel. He was a recipient of the 2010 wolf prize for outstanding PhD students in Israeli Universities. He is currently a postdoctoral fellow at University of California - Berkeley. Solomon's research interests include: very high grid penetration of intermittent renewable energy resources (Solar and Wind) with and without energy storage; the role of storage design and dispatch; long term planning of power grid, etc. His findings have been published in peer-reviewed journals, as book chapters, and conference proceedings.
