Renewable 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

Wave-energy

1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over

Photographic camera

Full account of the principle including experiments with five lanterns outside a room with a small hole was given by The Islamic scholar and scientist Alhazen (Abu Ali al-Hasan Ibn al-Haitham) (c.965 - 1039) Two clear descriptions of the camera obscura were given (1490) in the notebooks of Leonardo Da Vinci. Many of the first camera obscuras were large rooms like that illustrated by the Dutch scientist Reinerus Gemma-Frisius in 1544 for use in observing a solar eclipse. The image quality was improved with the addition of a convex lens into the aperture in the 16th century and the later addition of a mirror to reflect the image down onto a viewing surface. Giovanni Battista Della Porta in his 1558 book Magiae Naturalis recommended the use of this device as an aid for drawing for artists. First photographs taken with camera obscura were mostly landscapes, the reason for that was a long exposure time. And because landscapes do not move it was a

Biogas – The source of future energy

Methane leaks from landfills are an ongoing problem, as is the production of biogas in poorly maintained compost piles, manure lagoons, and outhouses. Spontaneous fires and explosions caused by build-ups of gas have been recorded in many regions of the world, illustrating a major problem which needs to be confronted by waste management companies. When this gas is trapped, however, it can be made useful, instead of just being a nuisance. Trapped biogas can be used to power stoves for cooking and heating, in addition to other applications. By trapping the gases, people can prevent methane from reaching the atmosphere, thereby reducing degradation caused by methane gas. The ability to turn waste products into something which can be utilized is also rather convenient, especially in developing countries, where available resources may be limited. Furthermore, by turning biomass into biogas, people can address
