- 3) Gas
Where Do fossil fuels come from and What Are They Used For?
- Fossil Fuels Form Underground For Over Millions Of Years.
- They Were Burnt To Provide Energy.
State The Steps Of How The Fuels Get To The Nation Grid and State The Energy Transfers Between Them?
- 1) The Fuel Goes Into The Boiler as Is Transferred As Heat.
- 2) Then The Fuel Turns Into Steam and Is The Transfer As Movement as it Move Around.
- 3) Then It Goes Through a Generator and Turns as Electricity to the national grid
What’s The Acronym To Remember The Steps Of How Fuels Get To The National Grid?
- B - Boiler
- S - Steam
- T - Turbine
- G - Generator
- G - Grid
Name 2 Pros Of Fossil Fuels?
- 1) Fossil Fuels are Reliable At The Moment There’s Enough To Meet The Current Demand.
- 2) Running Costs Of Power Plants And Extraction costs Are Quite Low.
Name 3 Cons Of Fossil Fuels?
- 1) They’re Finite They Will Run Out.
- 2) The Extraction Of Fossil Fuls Has Social and Environmental Impacts.
- 3) They Release Greenhouse Gases Which Cause Environmental Problems.
What Percentage Of Fossils Fuels Did The Uk Use In 2018?
- 77%
What Percentage Of Nuclear Power Did The Uk Use In 2018 and How Is It Produced?
- 1 Fifth
- A huge amount of energy can be produced through using a relatively small amount of
uranium
. The energy is produced as heat through the
fission
process.
Name 3 Pros Of Nuclear?
- 1) Nuclear Power Is Reliable.
- 2) Nuclear Fuel Is Quite Cheap.
- 3) Nuclear Power Is Very Clean- It Produces Low Levels Of Green Houses Gases.
Name 4 Cons Of Nuclear?
- 1) It Uses Fuel Sources That Are Finite.
- 2) Nuclear Power Plants Cost a Lot To Build and Maintain.
- 3) The Waste They Produces Is Very Dangerous and Difficult To Dispose Of.
- 4) They Carry Risk Of Major Catastrophe.
What Does Finite Mean?
- That It Will Run Out 1 Day (Non-Renewable Energy Sources)
What Percentage Of The Uk Used Renewable Energy Sources?
- a Third
What Does Non- Finite Mean?
- That It Will Not Run Out (Renewable Energy Sources)
(___________) Generate Electric Currents Directly From Sunlight.
- Solar Cells
How Does Tidal Barrages Work and Where Will They Be Placed?
- They Are Big Dams That Are Built Across River Estuaries With Turbines In Them The Flow Of The Tide Thean Spins The Turbines And Generates Electricity.
Write a Definition Of Nesting?
- Its Cutting Very Specifically and Minimize Raw Materials.
Name 3 Pros Of Renewable Energy Sources?
- 1) Renewable Energy Sources Generally Have a Smaller Environment Impact Than Other Energy Sources.
- 2) They Provide Clean Energy.
- 3) Once Set Up Costs The Energy Provided Is Usually Free.
Name 4 Cons Of Renewable Energy Sources?
- 1) Initials Costs Are Often Quite High They Also Don’t Produce As Much Energy Sources As Finite Sources So The Time Taken Is Quite Long.
- 2) They Really on external factors like sun,wind so they are less reliable.
- 3) They Spoil The Landscape and Look Ugly Also They Can Be Very Loud For People Living In The Local Community.
- 4) It Can Causes Possible Habitat Loss.
Name 2 Types Of Batteries?
The two main types of batteries that are commonly used are single-use and rechargeable.
Where Is Alkaline Batteries Sold
They Are available in supermarkets and shops.
What Are Tiny Batteries Know As And What Are They Used In?
- They are Know As
button-cell batteries. - They Are Used In power calculators and hearing aids.
What are Large Batteries Used In?
- Cars and Trucks.
Name The 3 Common Forms Of Batteries Which Are Found In Homes?
-1) AA
-2) AAA
-3) PP3
How Much Volts Does AA and AAA
Both contain?
- 1.5 Volts
How Much Volts Does PP3 Contain?
- 8 Volts
How Does Alkaline Batteries Help The Environment?
- It Helps The Environment Because They Leak Less Than Disposable Batteries Meaning Less Environmental Impact.
Name 3 Pros Of Rechargeable Batteries?
- 1) Are more economical in the long term.
- 2) Have a Limited lifespan.
- 3) Can Be Recharged.
Name 1 Con Of Rechargeable Batteries?
- 1) They Are More Expensive Than Single Hand Use Batteries.
What Will Happen If Batteries Are Not recycled correctly?
- They Will end up in Landfilled Sites And The Chemical Could Leak into the ground causing it to destroy wildlife and plants.
Write a Definition Of Kinetic-Pumps Storage System?
A kinetic-pumped storage system is a fast-acting electrical energy storage system Which Supplies Energy To The National Grid When The Demand Is at its Lowest.
How Does The Pump Storage System Work?
- It Works By Having 2 Reservoirs and a Hydroelectric Dam System.
What Happens At Night at The Storage System and What Happens To The Cost?
During night Time excess electricity is produced by other electrical energy stations, meaning the cost of the electricity is much lower, so a kinetic-pump plant will pump the water from a lower reservoir up to a higher reservoir.
