Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free.
Name at least 3 renewable energy sources. What consequence might there be if we use non-renewable energy too much? Which energy technology is the world's fastest growing? With what name is renewable energy also known as? Light Heat Electricity Generated from natural resources. Doesn't harm the environment. Can't be replenished Most of our energy. May cause global warming. Wind energy is the fastest growing. Most renewable energy comes from the sun. Hydroelectric energy is the oldest and largest source. Renewable energy a.k.a "green" energy. Thank you for listening! We use energy every day. It surrounds us in different forms, such as light, heat, and electricity. Our bodies use the energy stored in molecules of substances like carbohydrates and protein to move, breathe, grow, and think. We also use energy to do work and to play. Humans have invented thousands of machines and
Environment and renewable energy 1. How can we help bring about a change in behavior? * Renewable energy is the sun and the water that people use, but not yet so widely. Required on all homes, various stations, hypermarkets solar panels to use the potential energy, the stock of which is not completed within 5 billion years. * Renewable sources such as wind and solar are intrinsically unsuited to meeting the demand for continuous, reliable supply on a large scale – which comprises most demand in developed countries. The criteria for any acceptable energy supply will continue to be cost, safety, and security of supply, as well as environmental considerations. 2. How can we encourage sustainable development? * To encourage you in the following way. To allocate money for the construction of such
Natural resources-our treasure Natural resources are land or raw materials like minerals, fluids, gases, organic matters and also woods, groundwater, animals and so on, in other words it's everything that human hasn't created. These resources are also used in industry. We get natural resources from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources. Solar radiation, wind and hydroelectricity, are perpetual resources that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun

Hello My name is JOHN SMITH and I am here to talk about Hydroelectricity. Global energy use has risen by 70% since 1971 and continues to increase at the rate of 2% per year. There are many scenarios for future demand. One solution would be to use more hydropower. In 2005, renewable energy represented one-fifth of total power generation. Hydropower is the most advanced of the renewable and represents 87% of this production. 160 countries all over the world are using hydropower. Five countries make up more than half of the world's hydropower production. Those countries are: Brazil,Canada, China, Russia and the USA. (Production) *Most of the energy comes from the potential energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow
Which are the most problematic environmental problems and how can we avoid them ? To start with, the biggest problem is global warming. The temperature is rising due to air pollution, which is caused by smoke from factories and of rising levels of CO2 . As a result, smog and soot causes health problems. Also, a big problem is deforestation. Due to the fact that it is causing destruction of the rainforest, it contaminates the water. To solve these problems, we certainly should use renewable sources of energy and we need to avoid dangerous gases. For example, we should switch off lights every time when we leave a room. Moreover, we should take public transport more often and stop using CFC's. We can solve environmental problems only if we follow certain rules. that it is causing* ; renewable energy resources*; Therefore, we*; when we leave a room*; Moreover, we should take..* and stop using CFC's* We can solve environmental problems only if we follow certain rules.

Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos. Hydro-electricity has acquired great significance as a source of energy in the country in the present times and is being put to different uses
youtube.com/watch?v=B4VP129rWcY Peat properties Peat is an organic deposit formed from the accumulation of decomposed remains of plants in the oxygenpoor environment of excess water. Peat consists mainly of partially decomposed remains of plants and humus. The most essential indices of peat are decomposition degree, moisture content, mineral (ash) content, density and calorific value. Although peat is of biological origin, it is not considered a renewable biofuel usually, but a slowly renewable fuel of biological origin. The CO2 emitted to the atmosphere during its combustion is accounted as a greenhouse gas (GHG) similarly to fossil fuels.

owners and local government have taken measures to prepare for the worst. Additionally, many coastal states add sand to their beaches to offset shore erosion, and many property owners have elevated their structures in low-lying areas. As a result of the erosion and ruin of properties by large storms on coastal lands, governments have looked into buying land and having residents relocate further inland. How to help prevent global warming GREEN JOBS AND CLEAN ENERGY Choose renewable energy. Pick a Green-e-certified energy supplier that generates at least half of its power from wind, solar energy and other clean sources. If you don't have that option, look at your current electricity bill to see if you are able to support renewable energy in another way. DRIVE SMARTER CARS Choose an efficient vehicle: High-mileage cars such as hybrids and plug-in hybrids use less gas and save money. Over its lifetime, a 40-mpg car will save roughly $3,000 in fuel costs compared

The first windmill for electricity production was built in Scotland in 1887 to power the lighting in the cottage, thus making it the first house in the world to have its electricity supplied by wind power. During the Second World War, small wind generators were to recharge submarine batteries. In the 1990s, wind power became more important, because fossil fuels pollute the atmosphere and humanity needed alternative fuels. That's because wind power is so necessary. Wind power is also renewable energy and it doesn't cause greenhouse gases. Building windmills is actually quite expensive and they need repairing or replacing about every 12-15 years. And strong winds can also break the wind turbines. Considering these things the wind power cost more than the energy from fossil fuels. Also the turbines are unpleasant to look at and if you live near the wind farms then they make a bit noise. Wind farms take a lot of space which you can use for farming.
unlimited food and water and never thinks about those people who are in need. Due to the over consumption of water, gas, wood et cetera, we might be in a lack of mineral resources in the future. And if they run out, we need to find an alternative variant. Already today we have places on Earth were there are no clean water and fresh air. People are already trying to make the world a better place to live in but there are also people who still do not do anything to achieve it. People are using renewable energy (wind, sun), using less air pollutin fuels and recycyle as much as possible. It helps to maintain normal balance in the nature. Fast changes require us faster solutions for a normal life. We do not know what might happen in 10 or 100 years, but we are bound to consider, that life has to continue after us.

Air pollution in Japan Birgit Tohter Air pollution The presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. The effects of air pollution is global warming, heart problems, acid rains etc. There are solutions like public transport, cleaning smokestacks, laws, renewable sources, The history Industrial activity in Japan devoloped rapidly after the World War II. People became really sick and described it as more horrible suffering than death. In the 1970s Japan managed to clean up without sacrificing growth by investing in pollution-control technologies. They made new laws. It was the start of "Japan's Pollution Diet". Today, Japanese cities are among the world's least polluted, according to the World Health Organization. Air pollution in Japan
They carrie unique information which cant be restored. Maybe in the future, the technology will get so far that they can recreate some extincted spieces. Here is araucaria mirabilis which was living approximately 160 million years ago If we create some culture on the field or cut down some alder forest and replace it with spruces, will it have interaction to the whole world? It's extremely difficult to answer, because there are so many factors. 4. slaid Renewable resources have became metaphor with meaning that its easy way to produce energy. Its easy to destroy our forests but it changes our ecosystem. They cause blowdowns, erosions and so on. 5.slaid scope of history Forests sometimes need to be updated. We need to take down trees with diseases. But we cant cut down trees which have cultural information in them. There may have some text beaten in from thousands years ago.

change for the better. One way how to help the enviroment is saving energy. You should switch off anything, that uses electricity. If you’re not using it, then turn it off, it’s simple. This goes for lights, televisions and so on. Also try unplugging if possible, because even when an appliance is turned off, it still may use power. You could switch your light bulbs to LED light bulbs, because these are using less energy and even last longer. If you use renewable energy sources, you won’t cause burning fossil fuels, that causes pollution. Another way how to help the enviroment would be saving water. Turn off the water, when you’re not using it. People often leave water running, when they’re brushing teeth- turn if off between rinses! If you find a leak somewhere, fix it and in the meantime put a bowl orsm under the drip. Also you should conserve water. Take shorter showers, run your

person inhales about 20,000 litres of air. Every time we breathe. We risk inhaling dangerous chemicals that have found their way into the air. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for long time. To keep our environment to be cleaner we have to be more responsible. People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste and move to non-polluting renewable forms of energy production. Also, automobile-produced pollution can be decreased with highly beneficial results like a hybrid-cars. Many countries have green day weeks, when people don't use their cars, but they travel by buses or bicycles. Estonia has this week also. The 11tk edition of Green Week.

THE IMPORTANCE OF THE RAINFOREST The beauty, majesty, and timelessness of a primary rainforest are indescribable. It is impossible to capture on film, to describe in words, or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest. Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so

I chose this particular topic because I have always been interested in green energy. This topic gave me an excellent opportunity to improve my knowledge about these kinds of things. For me this report is a great challenge because I have not done anything like this before, especially in English. Primary goal for me is to improve my knowledge about renewable energy and also usage of English language. This report is going to talk about biogas. It provides a brief review of usage and future prospects of the biogas. I have tried to make this report as understandable as possible. By the end of this report I want to come to a conclusion whether biogas is the best source of future energy or are there any other sources that are better. What is biogas? Typically it refers to the gas produced by the anaerobic digestion or fermentation of
Kui neid toksilisi materjale ei käidelda korrektselt, siis võivad need üpriski ohtlikuks nii keskkonnale kui ka inimestele osutuda. 2.5. Globaalne soojenemine Kuigi päikeseenergiast elektri genereerimine ei põhjusta globaalset soojenemist, siis näiteks tootmine, materjalide vedu, installatsioon, hooldus ja demonteerimine võivad seda küll tekitada mingil määral.1 1 „Environmental Impacts of Solar Power“ [Võrgumaterjal]: http://www.ucsusa.org/clean_energy/our-energy- choices/renewable-energy/environmental-impacts-solar-power.html#.VEYyr7CsWKE 7 3. Päikeseenergia tootmine 3.1. Päikeseenergia ja elekter 17. sajandil kirjeldati esmakordselt elektrienergiat ka teaduslikult, ning alates sellest ajast on inimkonna elektrienergia kasutamine jõudsalt kasvanud. Seni pole meil päikeseenergiast aga peaaegu üldse toodetud elektrit, kuigi võimalused selleks on.
About 98% of Ireland's final energy demand is produced by burning coal, petroleum, peat, or natural gas. This over reliance on fossil fuels ( see liigne toetumine sisseostetavatele kütustele )-particularly oil - (eriti õli) has left Ireland vulnerable to international price fluctuations as it imports all of its oil needs. (on jätnud iirimaa haavatavaks tänu rahvusvahelistele hindande muutumisele ) There have been recent efforts in Ireland to use renewable energy such as wind energy with large wind farms being constructed in coastal counties such as Donegal, Mayo and Antrim. Flora Because of Irelands mild climate , many tropic species such as palm trees grow in Ireland. Much of the land is now covered with pasture(karjamaa) and there are many species of wild-flowers The country has been "invaded" by some grasses, such as Spartina anglica which you can see on the picture
In order to accomplish this, governments, scientists and environmentalists are using or testing a variety of methods aimed at reducing pollution. There are two main types of pollution control. Input control involves preventing a problem before it occurs, or at least limiting the effects the process will produce. Five major input control methods exist. People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste, and move to non-polluting renewable forms of energy production. Also, automobile-produced pollution can be decreased with highly beneficial results. Output control, the opposite method, seeks to fix the problems caused by air pollution. This usually means cleaning up an area that has been damaged by pollution. Input controls are usually more effective than output controls. Output controls are also more expensive, making them less desirable to tax payers and polluting industries.
surplus heat. The latter may, for example, be a by-product from production of automotive biofuel. District heating can provide cheap energy to consumers by using low-cost energy sources, such as wood, waste and surplus heat. Many of these resources can be of local origin and promote local business and industry. The main advantages with district heating are high security of supply through utilisation of domestic renewable energy resources, if available, low primary energy demand due to high conversion efficiency, as well as small CO2 emissions thanks to low fossil fuel use and the high energy efficiency. Incineration of waste with heat recovery to district heating may be used at very low cost. District heating also gives opportunity for cogeneration of power and heat with very high efficiency. District heating enables profitable heat supply with outstanding
proteins produced in your body and the proteins you eat. Another famous example of a polymer is DNA - the long molecule in the nuclei of your cells that carries all the genetic information about you. People have been using natural polymers, including silk, wool, cotton, wood, and leather for centuries. These products inspired chemists to try to create synthetic counterparts, which they have done with amazing success. Biopolymers (also called renewable polymers) are produced from biomass for use in the packaging industry. Biomass comes from crops such as sugar beet, potatoes or wheat: when used to produce biopolymers, these are classified as non food crops. Many types of packaging can be made from biopolymers: food trays, blown starch pellets for shipping fragile goods, thin films for wrapping. http://chemengineeringposts.wordpress.com/2012/04/15/polymer-raw-materials-history- continues/ (17.02.14) http://wiki
in their homeland. The Body Shop At HomeTM, the direct-selling arm, was launched in the UK in 1994, Canada in 1995, Australia in 1997, and USA in 2001. It has now rolled out in 48 states in the USA and is set to grow even bigger. The Body Shop continues to increase its environmental practices. In 2001, The Body Shop UK region and service centre head offices in Watersmead switched to Ecotricity providing them with energy from renewable sources. In addition, a number of The Body Shop® stores have now converted to green electricity while the rest of the stores are set to follow suit. Campaign successes include the Against Animal Testing campaign. The campaign led to a UK-wide ban on animal testing on cosmetic products and ingredients in November 1998 and led to the largest ever petition (four million signatures) being delivered to the European Commission in 1996.
