The document discusses various energy sources, including both dirty sources like fossil fuels and nuclear that cause pollution but are currently cheap, as well as cleaner alternatives like solar, wind, and hydro. It also explores emerging sources such as geothermal, ocean, wave, and potential future sources that harness planetary forces. Finding a long-term sustainable energy solution is a global issue due to interconnectivity, the long timeline to transition, transboundary effects, and importance of meeting increasing power demand.

1. Alternative energy source By Hayden

2. Dirty Energy Sources Fossil Fuel Causes lots of pollution Cheap but resources are running out Not Sustainable Coal Causes lots of pollution Cheap but resources are running out Not Sustainable

3. Dirty Energy Sources Nuke Clear It has lots of radioactive waste Nuke clear power might seem Not Sustainable Timber Burning wood means cutting down the forest There is limited power provided Small scale power plant Not sustainable

4. Clean Energy Sources Solar Power Really clean (zero pollution) Energy efficient Simple design = less problems Wind Power Really Clean Generates moderate amount of power Requires windy locations

5. Clean Energy Sources Hydro Power Medium clean It provides massive amounts of power Expensive to build Bio Mass (Dirty to Clean) Biomass energy takes garbage, and natural gasses from landfill and converts them into electricity Still causes pollution Can produce quite a lot of energy

6. New Energy Sources Geothermal Geothermal energy takes the energy from the ground There is high potential of this power plant in the future because there is a lot of energy in side the earth Trade Wind (High altitude) Trade winds are much faster than ground winds there for having more power It is also consistent (somehow we must hang wind turbines high above our heads)

7. New Energy Sources Ocean current Using ocean currents can provide us with lots of power It is not hard Wave Using the up and down motion of the wave to harvest power Takes space

8. New Possible Energy Sources Gravitation forces (planetary) Using planetary gravitation forces we may be able to harness energy from it Rotational forces (planetary) Using the earths rotation we may be able to take some energy from it  Don’t stop the earth from moving 

9. Global Issue?? Interconnected – It connects to global warming Long acting – finding better power sources takes a long time and a long time to change Trans boundary – it affects not one country but the whole world Significant – finding a new power source is important especially when the demand for power increases
