Venezuela is not the exception. The oil industry, the one that gives us the biggest income is the one which contaminates the most. One big and true evidence of oil contamination is the Lake of Maracaibo, which contains large ammounts of oil spills that have destroyed most of the nature down there. The other problem comes from our principal electricity provider: the Guri Dam. It's water level is going down very fast, and by adding the unfixed problems of the the Hydroelectric Power station, we got a big problem. Methodology : Methodology We start our solution from our slogan: "the answer is up there", and our answer is: Solar Energy. The sun provides tons and tons of energy everyday and we don't take advantage of it. Solar power is the generation of electricity from sunlight. This can be direct as with photovoltaics (PV), or indirect as with concentrating solar power (CSP), where the sun's energy is focused to boil water which is then used to provide power. Solar power has the potential to provide over 1,000 times total world energy consumption in 2008, though it provided only 0.02% of the total that year Solution : Solution Our proposal is to get solar power via Parabolic troughs, Solar Panels, Solar Towers and Compact Linear Fresnel Reflectors SOLUTION ONE: PARABOLIC TROUGHS : SOLUTION ONE: PARABOLIC TROUGHS A parabolic trough is a type of solar thermal energy collector. It is constructed as a long parabolic mirror (usually coated silver or polished aluminum) with a Dewar tube running its length at the focal point. Sunlight is reflected by the mirror and concentrated on the Dewar tube. The trough is usually aligned on a north-south axis, and rotated to track the sun as it moves across the sky each day. SOLUTION ONE: PARABOLIC TROUGHS : SOLUTION ONE: PARABOLIC TROUGHS SOLUTION TWO: SOLAR CELLS : SOLUTION TWO: SOLAR CELLS A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect.[19] This is based on the discovery by Alexandre-Edmond Becquerel who noticed that some materials release electrons when hit with rays of photons from light, which produces an electrical current SOLUTION TWO: SOLAR CELLS : SOLUTION TWO: SOLAR CELLS SOLUTION TWO: SOLAR CELLS : SOLUTION TWO: SOLAR CELLS Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity. Slide 12: SOLUTION TWO: SOLAR CELLS SOLUTION THREE: SOLAR UPDRAFT TOWER : SOLUTION THREE: SOLAR UPDRAFT TOWER The solar updraft tower is a proposed type of renewable-energy power plant. It combines three old and proven technologies: the chimney effect, the greenhouse effect, and the wind turbine. Air is heated by sunshine and contained in a very large greenhouse-like structure around the base of a tall chimney, and the resulting convection causes air to rise up the updraft tower. This airflow drives turbines, which produce electricity. A successful research prototype operated in Spain in the 1980s, and many modelling studies have been published as to optimization, scale, and economic feasibility. SOLUTION THREE: SOLAR UPDRAFT TOWER : SOLUTION THREE: SOLAR UPDRAFT TOWER SOLUTION FOUR: Compact Linear Fresnel Reflector : SOLUTION FOUR: Compact Linear Fresnel Reflector A Concentrating Linear Fresnel Reflector (CLFR) – also referred to as a Compact Linear Fresnel Reflector - is a specific type of Linear Fresnel Reflector (LFR) technology. Linear Fresnel Reflectors use long, thin segments of mirrors to focus sunlight onto a fixed absorber located at a common focal point of the reflectors. These mirrors are capable of concentrating the sun’s energy to approximately 30 times its normal intensity[1]. This concentrated energy is transferred through the absorber into some thermal fluid. The fluid then goes through a heat exchanger to power a steam generator. As opposed to traditional LFR’s, the CLFR utilizes multiple absorbers within the vicinity of the mirrors.
