Natural energy resources

Renewable energy

  • Wind
  • Solar
  • Hydroelectric
  • Tidal
  • Geothermal
  • Biomass

Non-Renewable energy

  • Oil
  • Coal
  • Gas
  • Peat

Natural resources are things in the world that are useful to people.

There are two types of natural resources

  • Renewable (infinite)
  • Non-renewable (finite)

Renewable resources

  • Can be used over and over again.
  • Won't run out( if used in a sustainable way).
  • example: water, fish, wind, wood.

Non- renewable resources

  • Can only be used once.
  • They will eventually run out.
  • examples: oil, coal, peat, gas.

3 positives

  • It combats climate change.
  • It can decrease pollution.
  • It is a reliable source of power.

3 negatives

  • It... (More)

Renewable energy: Solar Energy

Solar energy is the heat and light from the sun that is harnessed and converted directly into other forms of energy, such as electricity.

How solar energy works:

  1. Solar panels convert sun's energy into electricity.
  2. A converter changes this electricity, enabling it to power electrical items.
  3. The electricity passes through a breaker box to sockets in the building.
  4. Items such as refrigerators, computers and TVs can be plugged into the sockets for power.
  5. Any extra electricity created during very 'sunny days' can be credited [used later]

Advantages of solar energy:

  • renewable
  • clean, with no waste product
  • solar panels are inexpensive... (More)

How acid rain forms and its damage to farmlands and forests.

How acid rain forms:

1. Acidic gases [ Sulphur dioxide and nitrogen oxide ] are released into the atmosphere by factories, etc.

2. Gases get carried by the wind.

3.These gases gets dissolved in rain water to form acid rain.

4. Acid rain kills plant life, pollutes rivers and streams and erodes stonework.

Damage to farmlands and forests:

Acid rain leaches plant nutrients available to them from the soil and so affects agricultural productivity. Acid rain also affects the quality of agricultural products. It can damage the leaves of vegetables such as spinach and destroy tomatoes.

Acid rain weakens... (More)

Climate Change By Natural Causes

Climate change can result from natural processes and factors.

Examples of natural factors include:

  • Changes in the Suns intensity (strenght) e.g sunspots
  • Slow changes in the earths orbit (path) around the sun
  • Volcanic Eruptions

Changes in the Suns Intensity

  • Scientists have identified changes in the amount of energy coming from the sun that is linked to sunspots.
  • Sunspots are black areas that appear from time to time on the surface of the sun.
  • Sunspots occur on an eleven-year cycle where they rise to a peak number and then fall to a minimum number. This is known as a sunspot cycle.... (More)
