What are the negatives of using oil as an energy source
- Limited supply
- Produces pollutants
- Is expensive and dangerous to transport oil
What are the positives of using gas as an energy source
- Ready-made fuel
- Relatively cheap
- There is and abundant supply
- No waste
What does the negatives of using gas as an energy source
- Although abundant, the supplies Ltd
- Although it is cleaner than coal and oil it’s still pollutes
- Requires expense pipelines to deliver
What are the positives of using coal as an energy source
- Ready-made fuel
- Relatively cheap
- Relatively safe and inexpensive to mine for
- Can easily be converted into energy
What does the negatives of using coal as an energy source
- Nonrenewable
- Very polluting
- Transportation is expensive
What are the positives of using wood as an energy source
- Readily available
- Could never run out of trees are planted
- Local
What are the negatives of using wood as an energy source
- Trees must be planted as often as cut
- Inefficient-doesn’t produce much energy
What are the positives of using solar as an energy source
- Gives off no pollutants
- Quiet
- Once installed there is very little cost and energy is free
- No greenhouse gas emissions
- No moving parts required
- Requires minimal maintenance
What are the negatives of using solar as an energy source
- Not available at night or on the clouds
- Requires a very sunny environments
- Relatively low efficiency
- Require space for panels and converter
What are the positives of using waves as an energy source
- Free energy
- No fuel needed or waste produced
- Not expensive to operate or maintain
- Can produce a lot of energy
What are the negatives of using wave as an energy source
- Depends on waves-unreliable source
- Some can be very noisy
- Must be able to withstand waves
What are the positives of using nuclear as a energy source
- Little radioactive material produces a lot of energy
- Cheap materials
- Doesn’t give off pollutants
What are the negatives of new using nuclear as an energy source
- Expensive to run reactors
- Wasters toxic-storing safely is expensive
- Leakage of nuclear materials is very damaging
What are the positives of using HEP as a energy source
- Reliable in most cases
- Renewable
- Doesn’t pull it or use fuels and is very safe
What are the negatives of using H EP as an energy source
- Can affect wildlife and fails and droughts
- Expensive and there are a limited amount of reservoirs
What is the positives of using wind as an energy source
- renewable
- no fuel necessary and no waste gases
- potential for massive amounts of energy
- space efficient and getting cheaper
What are the negatives of using wind as an energy source
- noisy and ugly and threat to wildlife
- unreliable
- large upfront cost
What are the positives of using geothermal as an energy source?
- renewable
- no fuel costs and no harmful polluting gases
- simple and reliable
What are the negatives of using geothermal as an energy source
- areas which I are suitable are rare
- high construction costs
What are the positives of using biomass as an energy source
- Cheap and readily available-could be InfiNet
- Widely available
- Low-cost
- Doesn’t pollute badly
- Converts waste into energy
What are the negatives of using biomass as a energy source
- Little energy again
- Energy intensive to produce
What are the positives of using tidal as an energy source
- Renewable energy source
- Environmentally friendly-no gas is omitted
- Takes up a little space
- Effective at low speeds
What are the negatives of using tidal as an energy source
- Effectiveness of title plant has not been determined
- Could potentially be awful for environment
- Must be constructed close to land
What are the positives of using oil as energy
- Ready-made fuel
- Cheap to convert into electrical energy
- Is a reliable energy source
