Renewable Energy Resources and their Limitations Essay

Curiosity and desire have led man to the peak of material progress. Discontent has always prompted him to change his environments and living conditions. Change is fundamental law of life for no change no progress. The more the peoples of the world have tried to change and ameliorate and better their lot, the more they succeed. The magic wand behind the spectacular and sustained progress has been the scientific technology. When we survey the achievements of men in their historical perspective; we get a clear idea about technological development from the earliest days from simple to sophisticated. The Present era is the era where energy is the basic resource which is essential for living. The present age can easily be termed as Fossil Fuel†¦show more content†¦Renewable Energy Resources and their Limitations: It is commonly believed that world can fulfill easily through renewable sources of energy if the present energy resources are consumed completely. This is not true. It is estimated that renewable energy resources like wood fuel, farm wastes, solar heat etc. would be able to fulfill only 7 to 15% of the world’s energy requirements. The remaining resources i.e. wind and water power can only fulfill a very small percentage of energy needs while for solar energy, expensive infrastructure is required. Solar Energy As far as the solar energy and its usage are concerned, one major area is installation of photovoltaic solar panels, which will cost more than a consumer, can save in the form of electricity tariffs. However, a collaborative research that was conducted by the professors of University of Ferrara and Bologna revealed that the use of domestic solar PV panels can save up to 2000 kWh per square meter of energy and can work effectively for a period of 20 years. The following table gives a cost comparison of different energy resources.

Nevertheless,Show MoreRelatedIs Renewable Energy The Solution For Our Energy Problems?1453 Words   |  6 PagesIs renewable energy the solution to our energy problems? Energy that can be re-used or re-grown in a shorter period of time than, for example, a fossil fuel, is the simplest way of defining renewable energy. It is considered very eco-friendly as energy from resources such as oceans, the sun and the wind contribute very little to pollution overall when producing energy. The energy problem which we are faced with today is critical and governments, scientists and environmentalist continue to searchRead MoreAnalysis Of Renewables Or Bust And Its Effects On Our Health And Environment?1503 Words   |  7 PagesRenewables or Bust Many American cities have experienced the phenomenon of smog or haze at one point or another. This smog has led the general population, political leaders, and scientists to ask the question, â€Å"What produces this haze and what are the impacts on our health and environment?† (Fischetti). The average amount of energy consumed per person has dramatically increased over the past several hundred years (Christensen, 482). The prevalence of fossil fuel use in our world is a primaryRead MoreRenewable Energy Rural Areas Of China1520 Words   |  7 PagesRenewable Energy in Rural areas of China Introduction Currently , the development of renewable energy resources , reduce consumption of fossil energy , environmental protection and mitigation of global warming has become a common sense of every country in the world. Despite China as a developing country and its historically low emissions, China faces international pressure to control its carbon emissions, which China is already the world s largest carbon emitter, sharing 29% of global carbon emissionRead MoreWind Energy : One Approach From The Energy Crisis996 Words   |  4 PagesWind Energy: One Approach to the Energy Crisis Introduction The renewable energy from wind energy has become a popular method of producing energy. When the world realized fossil fuel emission are harmful to our atmosphere, many countries started to look toward renewable energy sources. In recent years the U.S. has given tax incentives and tax breaks for using a renewable energy sources. The U.S. has become the leaders in using wind energy for a renewable resources. Even though wind power energyRead MoreEssay about Renewable and Clean Energy1611 Words   |  7 Pagesthrough time, renewable and clean energy is increasingly the ideal solution to energy related problems we have to solve one way or another. Biofuel is currently one of the mainstream and highly supported solutions, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugarcane. Biofuels, unlike nonrenewable fossil fuels over extracted by people, contains the potential to tackle most of the problems people encounter when using fossil fuels. T his makes renewable fuels makingRead MoreCanada s Population Of Canada1182 Words   |  5 Pageskeeps raising, Canada’s energy demand will also increasing as expected in future. Natural resources and the human survival and reproduction are tightly linked together. The abundant resources can let human beings to live with a steady, and even better living environment and standard. Canada is a country which with plentiful resources, especially in crude oil, coal and other traditional energy are rich in reserves. Canada puts a lot of effort in promote clean energy and renewable energy’s research, developmentRead MoreThe Theory Of Going Green850 Words   |  4 Pageslive in, the paper we write on, the vehicles we drive, all need energy to be created or transformed from some natural resource to the final product. There are many ways in which we can reduce the negative impact in which we have on the environment, many of them are low or no cost actions that we can implement o n a daily basis. The whole theory of going green is so that we can all put forth an effort to switch to clean renewable energy sources. By purchasing products that can be recycled it show thatRead MoreGenerating Electricity1712 Words   |  7 Pagescharge. It is the most routinely and widely used energy. It is an energy carrier and a secondary source as we get electricity from the conversion of primary sources such as coal, gas, and solar energy. These primary sources are either renewable or non-renewable sources but electricity itself, is neither. The most common way to generate electricity is using fossil fuels such as coal, oil and natural gas. They are known as fuels because they release energy when they are burned and fossil fuels becauseRead MoreThe Wind Turbines Are A Dominant Method Of Harnessing Wind Power891 Words   |  4 PagesLondon, and make wind energy a sustainable energy resource. Three-blade wind turbines are a dominant method of harnessing wind power, but this t echnology has drawbacks which make it unsuitable for placement in London. Small Wind Turbines, owned by individuals and/or communities have attempted to fill the gap, but are only capable of supplying lower levels of power than a city demands. This paper assumes that wind power will continue be used in combination with other (renewable) energy sources, such asRead MoreMicrogrid Essay1312 Words   |  6 Pagesmicrogrids in the Kingdom of Saudi Arabia (KSA).
