Renewable Energy Systems - Research Paper Example

astest power manufacturing segments of the world now and there is urgent necessity to minimise the maintenance and operation costs of electricity production. This research essay will make an earnest attempt to elucidate the wind and hydropower generation of manoeuvres of both Australian and Bangladesh government, in particular, to minimise the global warming and of that USA, China, Brazil, Russia and Canadian governments in general by giving unique attention to various empirical studies and eminent authors’ views on the subject.

1-Introduction Both wind energy and hydropower comprises of the renewable energy mix, these bring a lot of economic, technical and environmental advantages both to the developed and developing nations. Energy policy makers all around the world are now paying great attention to harness the renewable energy as they have a duty to safeguard the environment thereby by restricting greenhouse gas emissions into the atmosphere. Both wind energy and hydropower are resources which are abundantly available all around the globe, the technology has been well advanced and proven technology, are having longest plant life and lowest operating cost and the plant life can be extended at minimal costs .

This research essay will analyse the hydropower and wind energy capabilities of Australia and Bangladesh in an exhaustive manner and that of USA, China, Russia, Brazil and Venezuela in a crisp. 2-“What is Hydropower?” As of date, hydropower is the largest renewable-energy source and about 16% of the globe’s electricity needs is catered by the hydropower and hydropower occupies about 80% of the globe’s renewable-energy resource. For 90% of their electricity needs, about 25 countries in the globe are now relying on the hydropower.

For example, about 99.3%. 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 to enhance the socioeconomic growth of these remote regions.

This paper makes a conclusion that Hydropower as one of the renewable energy helps to avoid about 225 million tons of CO2 emissions in the atmosphere in the USA, and this is equivalent to taking about 42 million cars out of the American roads. According to satellite imagery , the pacific Northwest which is the home of the majority of the hydropower projects in USA is an island of low carbon emission, and this is conclusive proof that hydropower can reduce the CO2 emission into the atmosphere.

Thus, renewable energy like wind energy and hydropower are the energies of the future and both Australian and Bangladesh government energy policy makers should give more priority in the near future to these sectors so as to afford a clean, economical and environmental friendly energy to its citizens.
