Kodutöö 1 17.09 1. What is site-specificity and Genius Loci (spirit of place)? Site-specificity is an abstract understanding of place/site what is used to manifest “best” qualities of it. Usually this term is used when nature, vocation and all spheres what around the place are analyzed and object (art object, building or installation) fits perfect in this place. Object needs to be in harmony (balanced) with the environment. Site-specificity is place character or atmosphere what human can feel but can’t scientifically measured. As I understood site-specificity is all what surrounds it: nature as greenery, nature as weather (climate), traditions of humans, history of the place, etc. Genius Loci is the spirit of place. How I understood Genius Loci is the idea that every a human has his own place in this world and every human needs to identify himself. Before modern timeline human was in opposite with the place where he lived, he tried to identify himself by self-realization and

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil
Green Energy Program paid for and brought to by -Anja Bananja -Franz the Manz - And Just Chadrick Overview- What is Green Energy? Different Types? What is sustainability? German Green Energy Cost and Efficiency Recycling What is Green Energy? -It is energy resources that are renewable -Can be naturally replenished -Clean, Safe and not harmful to the environment (aka mother earth) Types of Green Energy Green Energy going cute Solar Power · Is produced by using photovoltaic cells, which capture sunlight and turns that into energy. Problems ? -The sun has got to shine -The cost of solar panels and the systems range between $20k-40k -The light from the sun produces a very small amount of energy Wind Power -These giant pinwheels spin from strong winds which spins a turbine of a generator to produce energy.

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. Does not harm the environment. Click to edit Master text styles Second l
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 permeable structures). It is refined and separated
