The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas in the atmosphere. These problems drive researchers and societies to search alternative energy such as switching to renewable energy or carbon-free energy to replace fossil fuels. For example Nakata et al., (2011:465) show ‘low-carbon society’ …show more content…
Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.
This essay focuses on two renewable energy resources. First of all, biofuel is now accepted as alternative energy in worldwide. The figures continue upward trend in the biofuel production. ‘An annual growth rate of 6.8% from 2006 to 2030 is expected for total biofuels consumption in the transport sector’ (International Energy Agency: 2008 cited in Zhou, et al., 2009:S11). Significant leaders of the biofuel market are Brazil, the United States and the European Union. The results of research indicated that 92% of the world’s ethanol is produced by Brazil and US together, while 90% of the world’s biodiesel manufactured by the EU. In addition, several developing countries in Asia such as Indonesia, Malaysia, Thailand, and the Philippines have an enormous potential for biofuel production. Now these countries are
