Because energy is considered to be essential for generation of wealth and economic development, it becomes an extremely significant resource to many countries in the world. When thinking about energy, we need to think of two main elements:
- energy demand and
- energy supply
Countries in this regard aim to have a balance and hence develop policies and strategies. When determining world energy consumption and production, many factors play a significant role such as technology development and population growth. There is an intimate connection between energy and the environment. A society that seeks a sustainable development must line toward approaches that have no environmental impact.
