Energy is needed in transport, heating, industry and electricity production.
Energy sources can be divided into renewable and non-renewable energy sources.
Fossil fuels (oil, natural gas, coal) are the most widely used sources of energy on the planet. They are cheap and simple to use, but they contribute to climate change.
In the future, energy production should become dependent on renewable energy sources, such as water power, wind power, solar power and biofuels.
Key words: energy consumption, non-renewable energy sources, renewable energy sources, fossil fuels, peat, nuclear power, bioenergy, water power, wind power, solar power.
