 Abstract
 Most energy resources that are currently being used are based on fossil fuels. However if continuously consumed at this amount, there are only enough reserves left for 40 years of oil consumption, 200 years of coal consumption and 60 years of LNG consumption. To prepare for the future, there is a great need for the development and expansion of new renewable energy. Due to global environmental regulations and soaring price of oil the development, expansion of an alternative energy source is in full swing. To fulfill the climate agreement a worldwide energy revolution from fossil fuels to low carbon, clean energy is taking place. Countries are focused on reducing fossil fuel consumption and on expanding the new renewable energy industry. The International Energy Agency (IEA) predicts 12 trillion dollars of investment in fields like new renewable energy, electric vehicles, energy storage system (ESS), and smart grids(intelligence power grids). In the case of South Korea, the importance of new renewable energy is on the rise, connected to the current government policy of suppressing nuclear power and reducing ultra fine dust particles. To prepare for this situation our only option would be to replace fossil fuels with solar, wind, geothermal, and tidal energy. New renewable energy can be renewed unlike fossil fuels and is non depletable. Also it is a environmentally friendly clean energy that has low carbon emissions. Compared to fossil fuels new renewable energy requires higher initial development costs and continuous research and development. However there are less constraints on where they can be installed. Renewable energy consists of renewable energy like sunlight, solar , geothermal, water, wind, marine, bio, and waste and also new energy like fuel cell, liquid coal gas, and hydrogen energy. The investment and attention for solar and wind energy is especially high which is noteworthy. Solar energy is a very important future energy source and combined with our world class semi conductor technology, it could create high added value as a next generation strategic export industry. To achieved this goal the promotion of an institutional strategy and the development of key technologies is necessary. The technological development of wind power generation began in the early 1990s. It is drawing the most attention world wide because wind energy has the fastest tech growth and lowest unit generation cost among other clean energy sources. In 2004 7,976MW of energy was generated from win power world wide. It is growing 20% annually and it is estimated the 4GW of wind energy is reserved after 2010. South korea has announced that they plan to generate 20% of the nations’s energy from wind power by 2020. Thereupon, the need for a green energy tower, an urban-type power plant that converges solar and wind power for stable power production and energy storage through ESS, has come to the fore. However there is no utility in wind power generation in the inland and urban areas because South Korea’s average wind speed in falls short of 4m/sec. Therefore excluding the coastal and high mountain areas the installation and usage of wind power generators is nonexistent As you can see from South Korea’s plans for wind power generation, there is an urgent need for research and measures for inland and urban wind power generation. Therefore my research is on an urban-type green energy tower equipped with an energy storage system and Information & Communication Technology (ICT) control system, that converges solar power with an urban-type wind power generator that utilizes the difference in height and a wind augmentation device. For theoretical and experimental study, an experiment tower with a wind augmentations device and 1.5 KW and 3 KW vertical win turbines was constructed in Byeongcheon-myeon, Cheonan-si, Chungcheongnam-do. After conducting a MOCK-UP for one year, positive data was drawn. From this MOCK-UP experiment, it was found that efficient energy can be produced in the inland through a wind augmentation device that can generate power based on kinetic theory of gas, a vertical turbine that applies lift and drag, management of a gear box, and a stable energy storage system. Recently, vertical wind power generation has been used not only on the top of buildings, top of the Corral, streetlight but has been applied and utilized in various ways depending on where they are installed. Vertical wind power generators have simple inner structures and are easy to install and therefore globally many cases of commercialized vertical wind power generators with designs harmonious to urban buildings have been appearing. The purpose of this research is to demonstrate and present the effectiveness and validity of urban-type green energy towers utilizing solar power and wind augmentation devices.
