Saving energy provides benefits like saving money and helping the environment. It helps preserve natural resources like coal, oil, and gas that are used to generate energy. Considering a product's entire life cycle, from production to use to disposal, can help reduce energy usage. For example, lighter packaging for products like water bottles requires less fuel to transport. There are many ways to save energy at home, such as reducing heating, using more efficient light bulbs, and choosing products with lightweight packaging. Lighter objects also reduce the energy needed for transportation.

2. Saving energy
 Saving energy means decreasing the
amount of energy used while achieving a
similar outcome of end use. Using less
energy has lots of benefits – you can
save money and help the environment.
Generating energy requires precious
natural resources, for instance coal, oil or
gas. Therefore, using less energy helps
us to preserve these resources and make
them last longer in the future.

3. “Life-cycle’’
 What does “life-cycle” mean? What does it have to do
with energy use?
Nearly all everyday products have an impact in terms of
energy, especially when you consider their energy
requirements across the whole life-cycle: production,
use and end-of-life. In many cases the use phase is
dominating. Plastics, for example, are one of the most
resource-efficient materials available. In their use
phase, plastics products help to save more energy than
is needed to produce them: For example, when you
choose a bottle of water packaged in a light weight
material such as plastic, remember that lighter
packaging requires less energy for transport. Thus, less
fuel was used to power the truck that delivered those
plastic bottles.

4. Ways to save energy
 What can I do to save energy?
There are many sources on the web that give you ideas of
what you can do to save energy. Here are a few ideas to get
you started:
 Change your travel behaviour, think more in terms of public
transportation, if possible, walk or ride your bicycle instead of
taking the car
 Reduce your house heat by 1C, keep the windows closed while
heating, dress warmly
 Choose products that come with lightweight packaging
 Turn off lights and appliances when you are not using them,
use energy-saving light bulbs
 Reuse plastic bags for shopping and storage
 Use a microwave instead of a stove to reheat food
 Use rechargeable batteries instead of disposable batteries

5. The effect
 What effect do materials have on the
environment?
In our daily life, we rely on many materials. Wood,
metal, glass and plastics all have environmental
consequences. Think about the impact of every
product you use. For example, the lighter an object,
the less fuel is required to transport it. A heavy
suitcase in the boot of a car will require the car to
consume more fuel during its journey. The same
goes for all product packaging. Therefore, buying
food wrapped in lightweight materials thus helps
the environment.
