5. Pros of Solar Energy -lots of it. -It is environmentally friendly.
-it is all over the world.
-Solar energy is sustainable because there is no way we can over-consume.
-it is renewable.
-It is environmentally friendly and does not cause pollution.
- reduces energy cost
-low maintenence

6. Cons Of Solar Energy -Solar energy is very expensive.
-Energy storage is expensive.
-Requires lots of space.
-not steady

-storege is expensive

7. Solar Energy

10. Pros carbon free if using h2 and o2 can use renewable resources
does not need recharging
not much noise
not much moving parts
can run forever as long as fuel is supplied

11. Cons requires fuel that to be made prior
high cost due to expensive materials
hydrogen fuel not always available
not much reliability because its a new concept
little but growing infrastructure for delivery
low density fuel compared to gasoline
could become irelivent if batteries become reliable enough
safety concerns about hydrogen (less dangerous than gasoline)

12. In a fuel cell a oxidant and hydrogen cells come together to form a electronic compound.this form of energy can be used to even power a laptop of a small machine.
