There has been a recent shift in the UK away from fossil fuels and towards renewable energy sources.

19% of the UK’s electricity in 2014 came from renewable sources.

The main renewable energy sources are wind and bioenergy, but the usage of solar and hydroelectric are also beginning to increase.

This shift is because of increased awareness of environmental issues as well as reduced supplies of coal, oil and gas in the UK.

Energy surplus and deficit

Global energy consumption is uneven

  • People in developed countries (e.g. USA, UK, Sweden) can afford to consume more energy. Almost everyone in these countries has access to electricity and many use energy-intensive devices (e.g. cars).
  • People in less developed countries (e.g. Burkina Faso, Mongolia, Nepal) can afford to consume less energy. Access to electricity is more limited and people are less dependent on consuming large amounts of energy.
  • Countries that have large energy reserves and enough money to exploit them produce lots of energy.
    E.g. Iran - large oil reserves.
    E.g. Russia - large oil and gas reserves.
  • Countries that have few resources or can’t exploit what they do have because of finance or political issues produce little energy.
    E.g. Sudan - politically unstable and financially poor.
    E.g. Ireland - very few reserves.

Economic development
Recently, the wealth of some _______ countries has increased. This means that more people are buying more ______ goods that use energy (e.g. cars, TVs etc.)

Technological advances
The rise of … has resulted in massive increases in energy demands.

A

The global demand for energy is increasing for 3 main reasons:

Increasing global population size
More people naturally means that more energy is needed.
In 2011, the global population was about 7 billion. This figure is expected to rise to 9 billion by 2040.

Economic development
Recently, the wealth of some poorer countries has increased. This means that more people are buying more material goods that use energy (e.g. cars, TVs etc.)

Technological advances
The rise of computers, mobiles and tablets has resulted in massive increases in energy demands.

E.g. ____ has large reserves of ______ but is unable to develop nuclear power plants.

A

Factors Affecting Energy Supply

Physical factors

Supplies of fossil ____ will eventually run out.
Some countries have fewer resources than others.
Some resources are harder to access than others.

Technological factors

Some countries may not be able to afford the technology required to exploit their energy resources.
E.g. Niger has large reserves of uranium but is unable to develop nuclear power plants.

49
Q

negative impacts of energy insecurity:

Exploration of ______ and environmentally ______ areas is becoming more necessary as …
Such exploration increases the … production and can also cause environmental ______.

Reduced industrial output
When energy is scarce, factories …

A

negative impacts of energy insecurity:

Exploration of difficult and environmentally sensitive areas is becoming more necessary as fossil fuel reserves get used up.
Such exploration increases the costs of energy production and can also cause environmental damage.

Reduced industrial output
When energy is scarce, factories produce less or relocate to somewhere that has better energy security.

50
Q

renewable energy source:

Biomass
Burning ____, ____ or _________ for power, or using these materials to produce ______.
A good choice for low-income countries because burning biomass is relatively ______.
Only renewable if the biomass is sustainably managed.

Hydro
Hydro involves …
Disadvantages are that building dams is very _________ and can destroy __________.

Geothermal
Geothermal power involves …
Geothermal power is ____ to set up but only works really well in areas that are ________ active.

A

renewable energy source:

Biomass
Burning wood, plants or animal waste for power, or using these materials to produce biofuels.
A good choice for low-income countries because burning biomass is relatively low-tech.
Only renewable if the biomass is sustainably managed.

Hydro
Hydro involves harnessing the energy of falling water by trapping it in dams then letting it fall through tunnels that contain turbines.
