What is used to generate electricity in Trinidad and Tobago?
Natural gas
What are two (2) cons of using wind turbines to generate electricity.
They occupy a lot of space.
They generate a lot of noise.
They pose a risk to wild life (kill or injure birds).
Where are solar panels placed on houses and why?
On roofs mainly to increase the amount of sunlight they are exposed to.
Why is wind energy considered a renewable energy?
Wind is not depleted when it is used to create electricity.
How is hydroelectric energy generated?
Flowing water pushes and turns the blades of a turbine spinning a generator which produces electricity.
Name two (2) bad things about using non-renewables for energy?
They pollute the environment and they are a limited resource and we can run out of them one day.
What is a problem that can be caused by building dams for hydroelectric power?
Negatively affects wildlife.
It can cause flooding.
Why is solar energy best suited for use in the Caribbean?
Because we have unlimited access to sun during all seasons throughout the year.
How is wind converted into wind energy using wind turbines?
Wind moves the wind turbines creating kinetic energy which is converted into electrical energy by wind turbines.
Why is hydroelectric energy considered to be renewable energy?
Hydroelectric energy uses the energy of running water to produce electricity without reducing its quantity to produce power.
What does it mean if a energy sources (eg. coal and gas) is non-renewable?
It means that they are depleted when used to create energy and do not replenish quickly so we can run out of them.
Name three (3) advantages of solar energy.
It’s renewable, clean, and reduces electricity bills.
