Renewable Wind Power

A wind turbine is a device that converts kinetic energy of wind into mechanical energy. When mechanical energy is put to use directly in some equipment such as grinding stones or a pump, it is called a windmill. Instead, when it is converted to electricity for further use, the device is known as wind turbine or wind generator. Wind turbines are mounted at high elevation so as to receive a constant flow of wind power at higher average velocity. Usually, wind turbines need an average speed of 35 kilometer/hour or 11 meters/second. Wind velocity mapping is done before selecting a place for wind turbine. Higher the wind speeds, more are the chances to get continuous flow of electricity (Whitburn, 2012).
As terminology implies, 1- kW rated capacity wind turbine would generate theoretically maximum of 1 kW of power per hour, if continuous flow of wind with the average wind velocity is available at all the time; however, in all practical purposes it does not happen so because wind energy is intermittent. In the long run, wind turbines are found to generate electricity only at 10-40% of their rated capacity. This means that wind turbine with the rated capacity of 1 kW would generate between 2.4 kWh (1× 24× 0.10) and 9.6 kWh of power per day (1×24× 0.40) (Whitburn, 2012).
Wind turbines can be segregated on the basis of horizontal- and vertical-axis turbines. Horizontal-axis turbines have tail fins that keep blades facing the wind. A constant flow of wind keeps turning the rotor blades of the turbine, which is connected to the generator through a rotating shaft and gear-wheel assembly. ...

Renewable and Solar Power in the UK
The paper tells that the solar energy is an alternative for the more widespread fossil fuel based energy sources such as oil, gas and coal. The UK possesses 0.3% of global oil reserves. A peak for oil production in the UK occurred in 1999, and by 2010, this tailed off by 54%. There are indications however, that there could be an estimated 25 billion barrels of oil remaining in British waters. Tapping into these reserves however, would require a capital expenditure of around £60 billion so it would be very costly. As of 2010, oil production in the UK was 63 million tonnes, estimated reserves...

; (3) the power in the wind is proportional to the density of the air (Park, 1982). According to history, the practical use of wind power began with the Egyptians around 2800 BC when slaves were made to row overseas using sails which were further employed in lifting water and operating grain-grinding stones even to within the period when Persians built panemones or vertical-shaft windmills in 700 AD. Some other civilizations of the Middle East followed the same tradition whereas the Crusaders of the West are believed to have improved the windmill concept that led the Dutch to put up...

This essay stresses that Australian government has set a target of 20% of Australian electricity needs to be catered from the renewable- energy sources by the year 2020. As this is an ambitious target, this can be achieved by developing and harnessing more percentage of energies from hydropower and wind farms. Hydropower is environmental friendly as it creates no pollution and maintains the stream flow of the rivers and the ecological balance. With the help of micro hydropower projects, tiny villages and remote hilly areas can be given electricity through off-grid, which would definitely help...

In the past years, the increase in the petroleum prices, coupled with tendency of fossil fuel reserves and their dangerous effects that cannot be avoided and the lack of political stability in the sources of energy regions have led to the renewable energy systems study (Air-X, 2008). In this case, electrical energy is outputted by the systems of renewable energy systems like fuel cells and photovoltaic panels in direct current form. As a result, regardless of the fact that the electrical energy produced by the wind turbines is directly proportional to the wind velocity making it alternative...
