Land based Wind Farms



Kinetic energy in the wind connects to a generator
10 mph min
No toxic emissions
Wave and Tidal Energy



More expensive than other sources
No pollution
Not commonly used source
Requires body of moving water
Turbines are set in the ocean to ‘catch’ the motion of the waves
Renewable
Environmental impacts: hard to install, and impacts the environment (fish movement)
challenging maintenance in the salt water
Where found? European countries
Uber



Compared to taxis more efficient because drivers going on their way
Taxi’s are more expensive than Uber
Energy gas, electric, quicker,
Carpooling


Efficient
Social
Save gas
Saving maintenance
Taking cars off the road
Too many people in the car-distraction
Non-renewable fuel
Floating Wind Farms



efficient
Eco friendly – no emissions
6 million kWh per turbine per year
But they kill birds
Eye sore…
Subways/Mass Transit





Energy-fossil fuels—rails
Less emissions than individuals driving a car
Reduces traffic
Not a stop where everyone needs them
Still using fossil fuels
Nuclear Energy






Only use about 5% of the power provided possible energy
Most often used reactant uranium
Environmental risks—radioactive waste
Environmental pros—little to no emissions
Meltdown
Cement lined trenches-for waste
Hybrid Cars



Still use fossil fuels
Release toxins
Expanded to other transportation: planes, boats
Microwave

Need water to move the molecules.
Very small amounts of metal can go in. (clips on end of hamburger/sausage)
Not metal in china—can’t work with this metals
No plastic in microwave
No Styrofoam
Cheaper alternative
Use less energy
Non-renewable
Bicycles







Pros-no emissions
Low maintenance
Less expensive
Healthy
Cons-difficult in inclement weather
Takes long to travel
Few bike trails/get hurt on roads
Geothermal

Pros-enviromentally friendly









Little pollution—few emissions
Geo thermal replenished easily
Cons-minor environmental issues (earthquakes)
Heavy upfront costs
renewable if reservoirs are properly managed
10% of worlds energy
US is a leader in geothermal
Individual home use available everywhere
Electric plants—location specific—W. Coast/Hawaii
Hoover Dam



Pros-electricity to 1.3 m homes, no pollution, renewable energy, reliable, controls flooding
Cons-ecological systems destroyed, location specific (only around water sources)
Dam lifespan
