The issues of using renewable resources
By Ridhwan Sabur

The following report discusses the issues that could occur through the use of renewable energy sources. The impact of energy sources on global warming and climate change is escalating, this creates the debate whether to use renewable energy or not. However, these alternatives come at a cost. In a world that is rapidly industrialising and ...view middle of the document...

Fossil fuel is a type of energy that took billions of year to occur, the moment they run out, it will be very difficult to get them again.

2. Non-renewable energy sources contribute air pollution.
Combustion of fossil fuels produces toxic gases like SO2, CO, NOx, HC and CO2 out of which CO, NOx and HC (vehicles’ exhaust) are the primary causes of pollution in urban areas (Bose, 2010). Only 1% of cities’ NO2 are formed naturally, while the remaining amounts of NO2 is formed through burning of fossil fuels and from vehicle exhaust (about80%) (Australian Department of the Environment, 2013). NO2 is said to have unfavourable effects on humans’ respiratory system weakening the immunity of lungs, which causes problems such as wheezing, coughing, colds, flu and bronchitis (Australian Department of the Environment, 2013). NO2 with the combination of SO2, cause acid rain that destroys vegetation. SO2 also easily reacts with other matter to form up unsafe compounds like sulfuric acid, sulfurous acid and sulfate particles. Almost all of this gas is from human sources (coal, oil and gas) and affects human health in a negative way (Australian Department of the Environment, 2013).

Since Renewable energy has an extensive availability and is one of the cleanest energies, they are receiving more consideration in this world. However, meeting targets on renewable energy is assumed to have many economic, social and environmental costs (Michalena & Hills, 2012). These include significant impacts within local infrastructure. Even though, renewable energy sources are clean and inexhaustible, they cannot entirely be considered as ideal dupes for fossil fuels, in terms of efficiency. Furthermore, despite the fact that renewable energy sources like solar energy and wind energy comes absolutely free, considering the total cost of building and operating a generating plant, using these energy sources can be comparatively costly. Additionally, generating energy through renewable sources can affect wildlife and plant life undesirably.
1. Renewable energy sources in certain ways can be very expensive.
The relatively higher cost of most forms of alternative energy compared to fossil fuel sources of energy is one of the most dominant disadvantages of renewable energy sources. This is hindering the use of clean energy compared to non-renewable sources of energy. Generation and implementation of solar panels, hydro-electric power plants, geothermal plants and wind farms can be costly (BBC, 2013). It is said that it usually costs approximately a $3.5 – 6 million for a solar plant to manufacture 1 Megawatt which is seemingly too high (Shah, 2011). Upfront charges related to public notifications, hearings and environmental-impact studies may demand up to a several thousand dollars (Chua, 2008). Bio fuel is perhaps the most popular renewable energy source. It is thought to be a clean and an ideal energy source and a good alternative for fossil fuels. This type of...
