Alternative Energy

In a recent time, one of the biggest problems in the world is becoming shortage of sufficient energy. People warn about possible exhaustion of stocks of oil, gas other major resources such as iron and copper. For about forty years after the end of Second World War, the mineral raw materials provided almost all energy for humanity; as a result, people consumed it in big amounts. From the beginning of the twenty first century, the world power is based on non-renewable energy sources. Today the main energy resources are oil, gas and coal. New prospects of development of power are connected with searching the best parity of energy. High hopes in the world are assigned to the alternative energy sources, which advantage that it is infinitive and non-polluting environment; and now such sources are solar, wind and water energy. This research project will include Solar Power, Wind Power and Hydrogen Power, also in which areas of Kazakhstan they will be more useful.

As Jan Null, an adjunct professor of meteorology at San Francisco State University and a Certified Consulting Meteorologist with Golden Gate Weather Services said, “The world’s increasing need for clean, renewable energy has given greater momentum to efforts to build the next generation of solar-powered devices for both small and large-scale use. In a world where experts say humans need to reduce their carbon footprint, solar energy is a win-win proposition. Not only is it an inherently clean technology, but every megawatt of power produced by solar energy is one less that needs to be produced by fossil fuel”; humanity has to use renewable sources of energy, to more secure future and keep our world clean.

Previous generation also used solar energy in their daily life. One e...

Wind power could be most effective energy source in Kazakhstan. Wind energy is particularly promising in Kazakhstan at the Djungar Gate, 600 km northeast of Almaty and next to China’s Xinjiang Uigur Autonomous Region, the province with the highest installed wind capacity in China (Lewis 2007). Annual wind speed velocities average 10 meters per second (m/s) at a hub height of 50-60 meters (Johannes 2005), providing the potential for 1000 MW of wind capacity (Energy Sector Management Assistance Programme (ESMAP) 1997). A year-long Danish study of wind speeds describes the Djungar Gate region as the “best wind climate in the world”—the turbines would operate at a full load for over half the year (Petersen 1999).
