Museum2you: Energy content A sneak preview of the Energy content
in our Museum2you program, available for hire to communities
across NSW. Energy: Adding fuel to environmental challenges We
use energy for almost everything we do— turning on a light,
using the computer or taking a bus. This energy comes from a
variety of sources which can all be grouped into two categories:
non-renewable and renewable. Non-renewable energy comes from
fossil fuels such as coal, oil and natural gas. Fossil fuels
take millions of years to form beneath the earth, so they take
just as long to replenish themselves. If we continue to use them
at our current rate, we will eventually run out. Burning fossil
fuels is the biggest contributor to human-made climate change.
The fuels are burned (or combusted) to release the energy they
store. However, this process also releases greenhouse gases,
particularly carbon dioxide, into the atmosphere. Although
greenhouse gases occur naturally in the environment, extra gases
are gradually making the
