WARNING SOME OF THIS IS ON KEYNOTE
SOO YEAH
What is a ditcher
A ditcher is used to dig drains to dry out the bog, as the water content is usually around 95%
What is a grader
A grader is then used to level the bog, which in turn makes it easier to harvest peat
What is a miller
A miller harvests peat by scraping loose a thin layer on the top of the bog
What is a harrow
A harrow is used to dry out the loose peat on the surface
What is a ridger
A ridger gathers the loose dried peat into ridges
Why are bogs good for wind farms
Cut-away bogs are ideal locations for wind farms
- The land is flat therefore easily accessible
- The exposed landscape means there is no shelter from the wind
- There are few residential areas nearby, so there would be little objection to construction of a wind farm
- The existing power station previously run off peat could be adapted to use wind energy
Why are bogs a good wildlife sanctuary
Bogs are unique habitat and preserving them is important in order to maintain biodiversity.Creating a wildlife sanctuary would attract tourists to the area.This would also ensure the boglands keep their natural characteristics
Why are bogs good for forestry
Coniferous trees could be planted and used in the construction industry and to make furniture
why are bogs good for grassland
Grass could be planted, allowing for grazing of cattle and sheep
Give me five examples of renewable energy sources
- Hydroelectric power (HEP)
- Solar energy
- Geothermal energy
- Tidal energy
- Wind energy
What is HEP
hydroelectric power is created using the force of falling water.A dam is built across a river to trap the water.When part of the dam is opened the water rushes in.The water is used to turn a turbine which generates electricity.An example of hydroelectric power station in Ardnacrushu, in Co.Clare
What is solar energy
Solar energy is created using the heat and light from the sun.Solar cells on solar panels capture the heat and light and convert them to energy.Solar panels can be seen on many private houses
What is geothermal energy
Geothermal energy is created using the heat form the earths crust.Water is pumped deep into the Earths crust and heated by rocks.The heated water is pumped back to the surface where it can be used to heat homes.The hot water can also be converted to steam which is used to turn turbines to crate electricity.Iceland produces huge amounts of geothermal energy `
What is tidal energy
the power of the rising and falling tides can be used to turn turbines.This tidal energy creates electricity
