  • Renewable and Non-Renewable Energy

  • There are two types of energy sources: Renewable and Non-renewable

  • If the energy cannot be made again in a short period of time it is non-renewable.

  • Here are some examples:Coal

  • Here are some examples:Gas

  • Here are some examples:Oil

  • Here are some examples:Nuclear

  • If the energy can be made again naturally it is renewable.

  • Here are some examples:Solar

  • Wind Power

  • Biomass

  • Tidal

  • Which one is better for the environment?Renewable energy sources!

    Why? Produces little to no waste products, so minimal impact on the environment

    It is more sustainable and will never run out

    There are two types of energy sources: Renewable and Non-renewable. If the energy cannot be made again in a short period of time it is non-renewable, but if the energy can be made again naturally it is renewable. Here are some examples:Non-renewable energy sources come out of the ground as liquids, gases and solids. Oil, coal, gas and their products (such as petrol and diesel) are called fossil fuels. 1. Coal is a solid. Australia has enormous amounts of coal particularly in central Queensland. Most of the electricity generated in Queensland comes from coal-fired power stations. In these power stations the energy in the coal is transformed into electrical energy. This happens in various stages:

    Coal is burnt to heat water The water boils and turns to steam The steam turns a turbine The turbine turns a generator and electricity is produced.

    2. Oil and Gas: Oil and Gas are fossil fuels which were formed millions of years ago by decaying plants and animals remains. We burn oil and gas in power stations today. 2. Oil and Gas: Oil and Gas are fossil fuels which were formed millions of years ago by decaying plants and animals remains. We burn oil and gas in power stations today. 3. Nuclear: Nuclear fuels such as Uranium only need small amounts to create large amounts of energy. This energy is created in a Nuclear Powerplant to produce electricity. Renewable energy sources can be used over and over again to produce electricity. To build an energy supply for the future, we need to switch from fossil fuels to renewable options. Key sources of renewable energy are: Sun: (show solar panels) The Sun releases an amazing amount of energy. Solar panels are used to convert the Suns energy into electricity. The Sun can also be used to heat water. Wind: Wind is used to turn wind turbines and make electricity. Biomass: Biomass uses the energy from plants and waste materials to make electricity. For example, wood or animal droppings can be burnt to make steam that turns turbines to make electricity. Oceans and Rivers: Waves are created by the wind blowing across the sea and by the force of the moon. Wave power uses the energy of the waves to turn turbines that make electricity.
