We use energy all the time, for things we might take for granted; heating our homes, working on the computer, running machines in hospitals, and keeping food chilled in shops. As the world population increases we are using more and more energy, most of which is generated by burning fossil fuels that release high levels of carbon dioxide into the atmosphere — not good for climate change. However, there are lots of renewable sources of energy that are much better for the environment, like solar, water or wind.

In this zone you will meet one scientist who works with the council to work out the best way to use bioenergy on the roads, one who is researching how nuclear waste reacts with the environment and another who is trying to find ways of producing fuels from plant reserves. There is also a scientist trying to find new materials in order to stop global warming, and someone researching alternatives to oil so we can save more energy, food and water.
