False
What are Fossil Fuels are made of?
fossils, ancient plants and animals, dinosaurs
Does Solar Energy decrease or increase your T&TEC electricity bill and why?
Decreases because it uses less power from T&TEC to power devices, it used solar energy to reduce the consumption
What would the Greeks and Romans use Solar Energy for?
light torches for the gods
What does PV Cell stand for?
Photovoltaic
What is a solar farm?
Large groups of solar panels typically in a wide open area
What is the non-renewable source used to Cool and give energy to houses in T&T?
Natural Gas
Where does Solar Energy come from and how does solar panels work?
Solar energy comes from the sun, its works when Photon or light energy from the suns knocks electrons from the panel and causes them to flow.
What device would Ancient people use to harness Solar Energy?
Magnifying Glass
Photo _______ ________ make up this technology used to harvest the suns energy.
Voltaic Cells
Name 2 effects that often occur in the environment from non-renewable resources.
pollution; acid rain; disruption to plants and animal ecosystems
What causes a flow of electrons to create energy in PV cells?
The action of electrons knocking other electrons loose and moving into other spaces for other electrons causes a of flow of energy.
What are Solar Panels manufactured with?
hazardous material For example
When was Solar Energy first used AND for what purpose?
7th Century B.C. To light fires using magnifying glass
What role dose pv cells play in Solar panels?
helps absorb energy helping the solar panels generate it into electricity
What 4 different types of Renewable Energy?
Solar, wind, Hydropower, Geothermal, Hydroelectric, Hydrogen, Biomass
____ is the year readily available oil will be used up

what are the 2 types of silicon?
n-type and p-type
What does Solar Energy reduce and why?
What are Greenhouse Gases, Sun light energy is used, not nonrenewable forms of energy that will pollute the environment.
Name 5 devices or technology that can incorporate or utilize solar power
Calculators, solar chargers, Solar powered vehicles, solar cooker, solar water heater, Solar watch.
What is the difference between Renewable and Non-Renewable Energy, with 2 examples of each?
Renewable energy harnesses natural energy to produce energy that we can consume. For example, wind's natural kinetic energy is used to turn a generator, which produces electricity. And since the wind will continue to blow, it cannot be "used up." Nonrenewable resources can only be used once, and we can't produce more to replace what we use eg Natural Gas & Oil.
Explain why an electric car is not always good for the environment
depending on the source of electricity that charges the car- using fossil fuels and coal would be bad but using solar or wind would be good
