As the need for alternative forms of energy increases, the need for cost-effective alternatives increases as well. Cost is one of the biggest concerns that most nations have with alternative energy resources. The majority of alternatives have relatively high start-up and maintenance costs, which can make them unsuitable as a cost effective energy source.

Waste incineration has been around for a long time.  From the time that humans first discovered fire, people have tended to burn what was not needed.  During the 20th century, people began to understand that they could in effect kill two birds with one stone.  People could rely on waste incineration as a means of disposing of refuse they did not need, rather than creating larger landfills, and they could also use the process of incineration itself to create energy.

Green or renewable energy is fast becoming a source of great concern in the United Kingdom. The National Energy Foundation is actively seeking ways that it can widely promote renewable energy and sustainable development. Several different projects are currently underway in the area of renewable energy.

The need for an energy alternative has most nations looking in all directions, and one of those is coal as an energy source. Many experts see coal as viable alternative source of energy. It is not known as the cleanest means of producing energy, but it is a cheaper alternative.
