How does the resource create energy?
Blades of a wind turbine convert moving air, called
wind, into a spinning motion that spins the turbine.
The turbine spins a magnet inside a coil of wire to
produce electricity.
Mirrors focus the sun’s rays to heat water tanks. The
water boils to make steam. The steam is then used to
generate electricity
A dam holds water back creating a reservoir or lake.
The intake gate opens and gravity pulls the water
through the penstock.
The water strikes and turns large blades of the turbine
which powers the generator. The generators make
electricity.
Hot water is pumped from deep underground through
a well under high pressure. When the water reaches
the surface, the pressure is dropped, which causes
the water to turn into steam. The steam spins a
turbine, which is connected to a generator that
produces electricity. The steam cools off in a cooling
tower and condenses back to water. The cooled water
is pumped back into the Earth to begin the process
continues to repeat again.
Crops
Biofuels
Wood can be burned directly as fuel.
Starchy crops like corn, sugar cane can be ground
down to make alcohol which is added to gasoline to
make the fuel gasohol.
Use bacteria that produce methane gas by breaking
down biomass. This gas can heat buildings.
Soybeans can produce oil which can produce the fuel
biodiesel.
