Energy resources

• Energy can come from fossil fuels, oil and natura gas
• A renewable energy source is one of that is being or can be replenished as it is used meaning you wont run out of it
• an example of non renewable energy resource is fossil fuels : coal and oil and natural gas
• Fossil fuels can be burned to heat water. This produces steam the steam turn the turbine which powers a generator
• Advantages of fossil fuels is that its more reliable
• Disadvantages of fossil fuels is that its bad for the environment
• When fossil fuels are burned we call this reaction combustion

  fuel + oxygen= co2 + water
• Most fuels including coal contain carbon and hydrogen and may also contain some sulfur
• Burning fuels can result in carbon dioxide and carbon monoxide which is harmful for humans as it binds to blood cells around the body
• Nuclear fuels release energy through nuclear reactions which can break the atomic nuclei … proton and neutrons
• Energy released through the nuclear reaction is used to heat energy to produce steam similar to burning fossil fuels
• Nuclear energy leads to radioactive waste and is expensive but it isnt bad for the environment or emit any greenhouse gases
• A non renewable resource cant be replenished
• sulfur dioxide links to acid rain
• Biofuels have lower co2 emissions but require expensive Specialist equipment
• Wind is renewable but can be noisy and look uglt
• Hydro electric power is renewable and doesnt release pollutant gases but can harm the environment by flooding
• Geothermal is renewable because the Core remains hot
• Tidal is renewable and reliable
• Solar energy is renewable but is unreliable and expensive
• Water waves is renewable and doesnt release green house gases but can be expensive and machines can be damaged by storms or bad weather
