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...
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 thousa...

Environmental problems today Nowadays we need to stand face to face against the environmental problems in spite of our everyday routine, that may affect the nature. 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 i...

The environment in realtion to mobility/transport in Europe Air pollution is problem all over the world. Through some pollution comes from these natural sources, most pollution is the result of human activity. The biggest causes are the operation of fossil fuel- burning power plants and automobiles that combust fuel. Combined, these two sources are responsible for about 90% of all air pollution in the United States. All kind of pollutions can lead us to serious health problems. For example, air pollution is increasingly being cited as the main cause of lung conditions such as asthma - twice as many people suffer from asthma today compared to 20 years ago. Every year, 3.2m Europeans are diagnosed with cancer - the most common cause of death after heart disease. Most widespread are cancers of the lungs, breast and colon. Diseases such as bronchitis, lung cancer and heart diseases may all eventually appear in people exposed to a...
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...

We live in a constantly changing world There seems to be no stability or certanity about anything. Nations rise and fall, governments come to power and tumble, armies march and retreat, healthy people become sick and on and on the world goes. On the one hand the world we are living in is amazing, because science, medicine, technology, and so on are advancing at an ever-increasing pace. It has made our lives much easier than it was 100 years ago. For example we have phones, television, fast cars, eco towns, highrise buildings and so on. But on the other hand the world can also be frightful. People are starving, and do not have water to drink nor wash themselves. But somewhere someone has 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 vari...
3. slaid If we destroy some kind of spiece, we cant recreate it. 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.

Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2.1. Drivers of biofuels production Lal (2010) stated that "three inter-connected challenges face humankind in the 21st century": food security, climate change, and energy security. The world...
BARRIERS TO DISTRICT HEATING DEVELOPMENT IN SOME EUROPEAN COUNTRIES Abstract District heating (DH) offers low primary energy demand, high security of supply and small CO 2 emissions. Barriers to DH in the UK, Ireland, France, Romania and the Czech Republic have been compiled through publications and interviews. DH systems require large investments, have negative initial cash flow and long payback time, which obstructs financing. One actor should control DH from source to consumption. If the value chain is fragmented, contracts are required between the links. It increases risks and financing costs, like in the UK and Ireland, where DH is not established. There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provid...

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and perme...
