Tidal Power vs. Oil
Transcript of Tidal Power vs. Oil
Environmental impacts are local not global
Smaller cost per unit of energy
No pollution to affect animals
Passing fish are pulled with the current and can avoid hitting the turbine's blades
Society is developing different renewable energy sources in place of non-renewable energy sources
By: Sara Hayden and Elsie Jones
Disadvantages of Tidal Power
Specific locations with high potential
Large turbines affect the movement of marine animals
Construction disturbs fish
Reduces mud flats (places where birds feed on fish)
Expensive to construct
Reduces shipping and recreation areas
High risk of oil spills
Oil spills kill many animals when they're exposed to it's toxic contents
Oil cleanups are expensive and disruptive to animals
Oil washes onto coastlines
Pollutes water and Soil
If you consume oil there are short and long term effects
How is Energy Gained?
Energy is generated from tides in the ocean pushing underwater turbines which activate a generator that produces energy.
Advantages of Oil
Less reliance on other countries
One of the easiest sources to convert to energy
Easy to distribute
Without oil companies, many people wouldn't have jobs
Advantages of Tidal Power
Future of Tidal Power and Oil
Renewable in Place of Non-Renewable
Renewable Energy vs Non-Renewable Energy
Energy sources that will
never run out.
Energy sources that
will eventually run out.
Energy from oil is generated when oil gets extracted from deep in the ground and is then burned. The burning oil heats water, which gives off high pressure steam, which turns turbines that produce electricity.
~Eventually the non-renewable resources will run out and if we don't make substitutes we will be left with little to nothing
~Non-renewable resources pollute globally and will, over time, create a very uncomfortable and unhealthy world
has a lot of potential for the future
Can be improved with small changes
More reliable and predictable than other energy sources
Tidal turbines could provide more than 20% of the nations demand for electricity
does not have a lot of potential for the future
Oil rigs can be changed to ensure less spills
Contribute to global warming
Oil will run out soon
