Some questions that i am still not sure:Where can we buy solar panels.

Things i have learnt: There are many disadvantages in using fossils fuels and natural resources to generate electricity as they are limited and pollutes the environment. 

Things i have agreed with:Using solar energy is a lot more environmental friendly and that it is not available all the time so we still should have an alternate source of energy for backup.
