We all use electricity every day of our life. The use of electricity is simple and convenient and we all know that it comes straight from the socket. But how does it get there?
World Electricity Generation (2008 in %)

Electricity is generated in power stations and 42% of global electricity is coal-based. This substantial coal contribution has remained steady for many years. The IEA now projects that coal will become even more important and contribute over 45% to global electricity by 2030. Due to fast economic growth in developing countries, especially in China and India, but most of all because of its favorable price and availability, coal will continue to be the main source of electricity and even gain importance in the future. Coal combustion can only be replaced once mankind is in the position to employ solar energy for use in an efficient and cost-effective way.

Coal is readily available, reliable, can be easily produced and transported and at the same time is affordable in comparison to other energy sources. Thanks to the balanced distribution across all continents coal is also free from political pressure, which is probably one of the most important aspects for national energy security.
