Thermal power generation burning fossil fuels such as coal, petroleum, and natural gas has been used to produce electric energy. However, there are some problems. Environmental pollution is one of the main disadvantages of fossil fuels. When fossil fuels are burnt to generate electric energy, it generates carbon dioxide, which is one of the major causes of global warming. Global warming Rise in temperature of the earth cause in melting of polar icebergs, as a result submerging low area by rising in sea levels (Rinkesh, n.d). Besides, it is also well known that extracted with dinosaurs or ancient plants, fossil fuels will be finished in the near future. According to the Energy Information Administration (EIA, 2009)., It is estimated that they will have disappeared in 30 to 40 years. In other worlds, since they are non-renewable, their costs will gradually increase until there is nothing more left. …show more content…
Fossil fuels are being consumed continuously by human even at this moment. We have to implement renewable energy sources such as sunlight, wind, rain, waves, and geothermal heat and substitute fossil fuels we use for them. Renewable Energy policy Network for the 21st century[REN21](4 September, 2014) explains that renewable energy amounted to 19 percent to humans ' global energy consumption in 2012 and occupies 22 percent of released electric energy in 2013. In addition, they also show that advanced countries invest developing renewable energy more than US$214 billion in 2013
