Wind Energy
What is a benefit of wind energy?
It’s clean and doesn't require fuel.
Why is solar energy renewable?
The sun provides constant energy.
What is biomass energy?
Energy made from plants or organic waste.
What is renewable energy?
Energy that comes from sources that don’t run out.
How do wind turbines produce energy?
By converting wind into electricity.
True or False: Hydro-Power can provide energy 24/7.
True, unlike solar and wind
How do solar panels work?
They capture sunlight and turn it into electricity.
Biomass and biofuel can be used to power what?
Transportation and heating systems
Why is renewable energy better for the environment?
It doesn’t cause as much pollution as other forms of energy.
Why are wind farms built in open areas?
Wind blows stronger and more steadily there.
Why is water used in hydroelectric power?
It can turn turbines as it flows.
What is one challenge of solar energy?
It only works well with enough sunlight.
True or False: Biomass and Biofuel cannot create air pollution.
False: They can still can create some air pollution when burned.
What makes a resource sustainable?
It can be used without running out.
Some people are concerned that wind turbines can harm what animal?
Birds
What does a hydroelectric dam do?
It uses flowing water to spin turbines.
How do engineers improve solar power?
By making panels more efficient or investigating storage solutions.
Biofuel is created through a process called what?
Biodigestion
Why are cities using more renewables?
To reduce pollution and save resources.
A 2,000 kW wind turbine avoids about how many tons of carbon emissions a year?
4,000-4,500 tons of carbon emissions yearly!
Which NJ Dam produces 30 million kilowatt-hours a year, enough to power about 11,000 homes?
Great Falls in Paterson NJ
A 10kW solar roof can eliminate about how many tons of carbon emissions a year?
4 tons of carbon emissions annually!
Biomass & Biofuel have the potential to reduce carbon emissions from which percent?
40-90%, depending on source.
Why are fossil fuels not renewable?
They take millions of years to form.
