RENEWABLE ENERGY
SOLAR ENERGYCan be used to:-Heat water-Heat spaces-Run electricity (electronics,
appliances)
Works from PHOTOVOLTAIC devices (PV)
P R O S
No pollution or CO2 emissions
When on buildings, they have minimal impact on the environment
RenewableSaves $Low maintenance
C O N S
Sunlight not always constant (weather, location)
Requires a large surface to collect sun energy to power a building
Installation is expensive
HYDROGEN
ENERGY
HYDROGEN ENERGY-Can be made from stored Hydrogen (not
common)-Can also come from fossil fuels, hydrocarbons,
biomass, and water, sunlight, wind, and nuclear sources.

HYDROGEN ENERGY
P R O S
-no pollution-no moving parts-operates at
higher efficiencies than normal fuels
C O N S
-More expensive-cars not built to
hold fuel cells-may still require
fossil fuels-H2 is hard to store
or transport-few refilling
stations
WIND ENERGY

WIND ENERGY
P R O S
-sustainable-Non-polluting-continual-low
maintenance cost
-proven effective
C O N S
-unreliable and depends on wind patterns, temp, time of year
-equipment is expensive
-initial expense is high
HYDROELECTRIC ENERGYP R O S
-sustainable-Non-polluting-controls flooding-recreational
opportunities-low expenses after
initial cost-lasts longer
C O N S
-changes to river ecosystem
-lowers water quality, pollutants back up in lake
-effects fish migration
-long construction process

ENERGY
WHAT IS IT?It’s heat energy from the earth

GEOTHERMAL ENERGYP R O S-sustainable-mostly non polluting-energy can be
produced non-stop-minimal expenses
AFTER initial costs-minimal impact on
stations that collect the energy
C O N S
-limited locations-constantly
replenishing water
-could contaminate groundwater
-CO2 and H2S could possibly be released
-pricey installation

BIOMASS FUELS
P R O S
-reduces/equals out greenhouse gases (CO2)
-gives an alternate to fossil fuels
-almost everywhere-reduces waste
products
C O N S
-uses food crops-increases price of
food and livestock
-takes more energy to produce then it makes
-expensive
