Abstract The provision of sustainable energy can be achieved using renewable energy sources due to the fact that renewable energy sources are unlimited. Furthermore renewable energy sources are naturally replenished on a human time scale. This report will comprise of a brief overview of renewable energy sources, namely solar, hydropower, geothermal and bioenergy and a further detailed report on the use, availability, utilisation and provision of wind as a renewable energy source. Lastly the various advantages and disadvantages of such a resource will be examined. 1.
These primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your home and business. 7 Types of Renewable Energy Sources 1. Solar Energy One of the first renewable sources of energy is sunlight. It is the reason why life on the planet Earth has flourished and is the one truly renewable source of energy. About 70% of sunlight gets reflected back into the space and we have only 30% of sunlight to meet up our energy demands.
Nuclear would play a large role in reducing the greenhouse emissions and solve the climate problem in order to assure that there would not be an escalation in global warming (Knapp et al, 2010). Some suggest that renewable energy sources would be able to achieve the same ends as nuclear power in providing a clean energy source to reduce emissions for the environment; however, they would be unable to meet the increasing energy demands. Compared with nuclear energy, the renewable sources are unable to replicate the type of power generation that is needed to power the grids making nuclear energy a better choice. Loudermilk (2011), a research associate for the Institute for National Strategic Studies, warns that “On the global level, without nuclear power, carbon dioxide emissions
There is diversity of energy we use in general, which is necessity in the society. So of course there are several area filling with energy generating factory to generate and some chemical materials from generating as well. In these days, especially nuclear became effective and important high technology to generate energy, however there are also negative aspects. You can imagine positive way but you need to consider both ways to accept nuclear power to be a safe energy source. This paper will provide mainly both positive and negative benefits from nuclear, what is nuclear, how it effects to human body and health, how it should be and solution.
By harnessing energy from the sun, dependence on more environmentally harmful sources as oil and coal can be decreased.This is a great alternative to these nonrenewable resources. Solar energy reduces the destruction of pristine forests.These forest make carbon dioxide to clean up the toxins in the air. Without all of these forest the climate changes rapidly. Solar power keeps this from happening. A positive effect of solar power is that it saves you money.
Although currently methods of obtaining energy may not significantly alter lifestyles throughout the world, society needs to remain attentive to consequences of non-renewable energy and seek productive ways of accessing renewable energy to help improve the environment and conserve fossil fuels. For many years, fossil fuels provided a cheap and reliable source of energy, but in recent years, scientists began to question the safety and supply of the energy sources. Many scientists attribute the controversial topic of Global Warming to the high amount of carbon released from fossil fuels. If Global Warming concerns scientists about the environment, one of the options to reduce the amount of Global Warming stems from a transition to renewable energies. Along with the environmental effects of fossil fuels, rates at
Almost none of the fuel sources that we could use provide Co2 or other pollutants. Economic values could also come from renewable energy. Most of the Energy projects are located away from big cities. These benefits could bring local service as well as tourism. Although the pros are very big there are some cons.
Renewable energy is known to be a ‘cleaner’ form of energy as consumption of this kind of energy will not produce carbon based emission gases that contribute to global warming. Moreover, renewable energy sources are abundant in supply as they are self replenishing. However, there are still limitations associated with its use. The first being its cost. Renewable energy plants need to be substantially large, much larger than a fossil fuel plant, in size in order to supply the needed amount of energy9.
Natural gas emits some of green house gases too like carbon dioxide which cause change in climate and cause global warming. Non-conventional energy source (renewable): Non-conventional energy sources are the one which are called as renewable resources too because they can be renewed. Examples of renewable resources are solar energy, bio-energy, wind energy and tidal energy. Biomass: Biomass is a renewable resource which can be renewed easily and is formed from organic matter. It occurs in the form of living or recently living plants and waste and is contained inside the plants and animals.
