Alternate Energy Source
By jose
Wind
- Wind makes the turbine spine powering an electric generator
- Clean energy source
- Preserves land for other uses
- Not constant in some places
- Turbines alter the landscape and natural aesthetics
Solar
- The heat from the sun is captured in solar panels
- Available anywhere the sun shines
- Clean and quiet
- Only harnessed during the day
- Solar panels are only about 20% efficient
Hydroelectricity
- Water flow is used to power turbines that generate energy
- Clean energy source no chemical reaction
- Water flow can be regulated to match demand
- Dams are expensive to build
- Dams can destroy animal habitats
Geothermal energy
- Heat is mixed with water to create steam which power turbines to make electricity
- It is clean and quiet energy source
- There is more then what humans can consume
- Locations are limited by drilling is limited so it can only be drilled where the heat is close to the earths surface
- Outside fuel is needed to power machines used to produced it
Biomass
- Essential solar energy stored in plants during photosynthesis
- Can turn waste into energy
- Keeps methane out of the atmosphere
- Lots of water needed to produce biomass energy
- It can emit air pollution and green house gases
Nuclear energy
- Splitting a uranium atom and taking the energy
- There are 4 nuclear power plants in the US
- 17% of the nuclear electricity is produced in the US
- Power plants produce energy or electricity
- Splitting an atom is called fission.
