To meet the increasing global demand for energy, while reducing the risk of damage to the environment or contributing to global warming, it is important that:

Countries find new types of energy, whilst developing and expanding existing sources that are more sustainable than fossil fuels.
Industry and domestic users of energy use it more efficiently (ie stop wasting it).
MEDCs start to switch from fossil fuels to alternative sources.
As LEDCs start to use more energy they are encouraged to develop more sustainable sources of energy.
The purpose of sustainability is to manage resources or run projects or industries, so future generations can use the resources too.
International concern has led many countries to try to reduce their use and consumption of carbon-based fossil fuels. Many governments signed the Kyoto Protocol, committing them to reducing greenhouse gas emissions.

With energy consumption rising, it is important that industry, transportation and consumers in their homes use energy more efficiently, so that less is wasted. This will also save money on fuel bills. We can all help by making changes to our lifestyles and our houses.
Examples of energy efficiency
Walking, cycling, or using public transport rather than fossil-fuel powered cars.
Using smaller more energy-efficient cars.
Reducing the number of aircraft journeys taken (especially short-haul flights).
Switching off lights, power sockets, phone chargers and TVs when not in use.
Using energy-efficient light-bulbs and rechargeable batteries.
Recycling and reusing plastics and oil-based products.
Insulating house roofs, blocking drafts, using double-glazing and more efficient heating systems.
Considering introducing solar panels, or switching to an electricity supplier that supplies green electricity.
