World Energy Outlook, IEA has projected that the world primary energy demand is increasing by 1.5% per year between 2007 and 2030, from just over 12,000 to 16,800 million tonnes of oil equivalent (Mtoe) with an overall rise of 40% . Figure 1.3 shows the world energy mix in 2008  and 2030  in the Reference Scenario based on current policies. Assuming similar rates of consumption and the economic conditions in the future, World Oil indicates that oil reserves in the world would be depleted more or less in 43 years, coal in 417 years, and natural gas in 167 years . The total energy mix size is projected to increase from
II, 294.9 Mtoe in 2008 to 17,014 Mtoe in 2030 in the Reference Scenario with the current policies as estimated by the IEA ...Read More
Energy plays the most vital role in the economic growth, progress and development, poverty eradication, and security of any nation. Uninterrupted energy supply is a vital issue for all countries today. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible, and environmentally friendly. Security, climate change, and public health are significantly dependent on the energy as schematically shown in Fig. 1.1. Abundant, cheap, and clean energy are prerequisites for decent human living conditions and a healthy economy...Read More
Access to electricity considered as a fundamental human need is still very biased in the twenty-first century. Numerous developing countries are deprived of electricity, while such an issue is generally inexistent in developed countries; nevertheless, the energy sources that made the development possible are mainly based on fossil fuels that raise more and more environmental concerns.
Renewable energies are a good option to equilibrate this situation and provide a real opportunity for a better environment. Their successful implementation cannot be followed unless governments adopt adequate favorable policies that should necessarily go along with good education...Read More
