| Term | Definition |
| Renewable energy | Comes from sources that will never run out.
E.g wind, solar and water |
| Non renewable energy | Comes from sources that will eventually run out.
E.g oil, coal and gas |
| Hydro electric power | Creation of electricity by using the force of falling water.
A dam is built to trap water, when it is opened, water gushes through. This spins a turbine that generates electricity. |
| Wind energy | Force of wind to turn turbines and create electricity. |
| Solar energy | Created using heat and light from the sun.
Solar cells on dollar panels capture the heat and light and convert it into electricity. |
| Geothermal energy | Energy created using heat from the earths crust.
Water is pumped into the earths crust and heated by rocks. |
| Biomass | Comes from organic material. Used to produce biofuels, which is used in machinery. |
| Hydroelectric power in Ireland | First and largest HEP station was built in Ardnacrushabin Co, Clare in 1927. |
| Advantages of HEP | Cheap, clean and renewable.
Water in dams can be a water supply for local areas.
Dams can prevent flooding.
Reservoir can be a leisure facility. |
| Disadvantages of HEP | Reservoirs mean loss of farmland.
Families may have to relocate.
Dams stop fish swimming upstream, which reduces fish stock. |
| Wind energy in Ireland | Strong winds come from the Atlantic Ocean, so Ireland has many wind farms.
Irelands largest wind farm is located in Galway wind park, which has 58 turbines. |
| Advantages of wind energy | Clean energy source,
Reduces our need to import energy.
Creates employment, |
| Disadvantages of wind energy | Wind is unreliable.
Expensive to build.
Noise and visual pollution.
Hazardous to local wildlife
Can lead to mass movement near bogs. |
| Consequences of energy production | Burning fossil fuels leads to:
Global warming
