From trees and plants to bugs and birds, every living thing on Earth is a form of energy. And all living organisms create energy, too, in the form of their waste. The energy of living things is called biomass, and it can be used to power the things that we need in our everyday lives, from washing machines, cars, and computers to the heating and lighting used in our buildings. Find out more about biomass, how it is sourced and used, and why this form of energy could help us find a more sustainable way to power our lives in the future.

We live in an energy-rich age, in which we can turn on a light with the flick of a switch or drive anywhere by turning a key. But, our vehicles, factories, and power stations, which create the electricity needed to light and heat our buildings, pump carbon dioxide into Earth’s atmosphere. Carbon dioxide overload from these human activities is making our planet hotter and hotter - and is causing the Earth's climate to change. Find out what scientists are doing to find sustainable new forms of energy that will secure our planet’s future.
Earth has a limited supply of fossil fuels, and in the near future this supply will come to an end. However, more people live on the planet than ever in its history - and they all need energy.
