how can renewable energy replace fossil fuels?
features
pros
may help avoid climate change
easily accessible
zero greenhouse gas emissions
unlimited supply
low cost
no concerns over warfare
if someone doesn't live in an area where the sun shines a lot (no solar power) the wind could most likely make up for that (wind turbines) and if they don't live in an area with lots of wind, water could make up for that (hydropower)
cons
forms of renewable energy
solar power
how it works
generates electricity
goes into solar panel which generates energy
allows photons to knock electrons free from atoms
features specific to solar power
pros
solar panels will work even if it's cloudy or rainy
saves a lot of money
no maintenance required for solar panels
solar panels can last for over 30 years
reduces the cost of electric bills
little to no concerns over warfare because everyone has sunlight
cons
what if it's really cloudy for a long time?
you have to hire a professional to install a solar panel, and the cost may be high
solar panels could get damaged in storms
you wouldn't be able to plug devices in at night unless you stored potential energy
wind energy
how it works
propellers turn a rotor
rotor is connected to main shaft
main shaft spins a generator to generate electricity
the wind turns propellers on a wind turbine
features specific to wind energy
pros
won't pollute the air because it is the air
not everyone has to install a wind turbine in their yard
much cheaper because everyone has wind
electricity will still work even during a bad storm
especially if it's really windy
if it's really windy during a storm you would probably even get more energy
instead of toxic nuclear factories, we would have wind farms where there's just a large field of wind turbines
easily accessible form of energy
cons
what if people live in an area where there is very little to no wind?
people might move to very windy areas for energy and the areas could become overpopulated
most windy places are far away from cities
birds could be killed by accidentally flying into a spinning rotor
hydropower
how it works
captures the motion of water
turbine converts that kinetic energy into mechanical energy
generator turns the mechanical energy into electrical energy
features specific to hydropower
pros
no pollution
reliable source of energy
very cheap
doesn't emit any gasses
safe
cons
could cause droughts
could cause flooding
could mess up ecosystems
modifies water sources
expensive to build
how could it help the environment?
no pollution
practically unlimited source of energy
reliable source of energy
much cheaper than fossil fuels
how could we replace fossil fuels?
replace with solar energy
tear down fossil fuel factories
replace those with solar energy related buildings
neighborhood powered by solar panels
solar panel factory
powered by solar panels
sunlight farm
huge field of solar panels to collect energy
energy is transmitted to nearby homes
no air pollution from chemicals anymore
replace with wind power
tear down fossil fuel factories
replace with wind power relate buildings
neighborhood powered by wind turbines
wind turbine factory
powered by wind energy
wind farm
huge field of wind turbines to collect energy
energy is transmitted to nearby homes
no air pollution from chemicals anymore
replace with hydropower
tear down fossil fuel factories near a large body of water
replace with hydropower related buildings
neighborhood powered by hydropower
hydropower generator factory
powered by hydropower
hydropower plant
no more air or water pollution
replace with all 3
tear down all fossil fuel factories
replace fossil fuel factories with renewable energy related buildings
sunlight farm
solar panel factory
wind farm
wind turbine factory
hydropower generator factory
hydropower plant
homes
homes could have solar panels on roof
backup source of energy if it's dark could be wind turbines
wind farm generates energy
stores energy in case of emergency
people who live on or near a beach could have hydropower as their main source
beach houses should also have solar panels on roof
wind energy could be last option
