We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy.
Energy, greenhouse gas and climate change. Energy is an important part of our lives. We all use energy everyday for transportation, heating, cooling, lighting, manufacturing and entertainment. The choices we make about how we use energy impacts our environment and our lives. We use energy in lots of different forms such as electricity, heat and fuels, like petrol. In Victoria more than 90 per cent of our electricity comes from brown coal. Gas contributes around 4 per cent.
