      This is a great question!

      It is possible that at some point we will have to depend on that type of energy since fossil fuels could eventually run out. Also, solar power is ‘clean energy’ and we really want to keep our Earth as it is.

      The other type of energy that people might try and use is fusion power. This is where 2 light atomic nuclei fuse to make a heavier nuclei and this releases a bigger amount of energy than it took to make the heavier nuclei. This reaction is kind of like the reaction that happens in the sun to release energy. However, it is realllyy tricky to do and there is also some radioactive waste which isn’t ideal.

      I personally like the idea of having a house roof which is made of solar panels and a wind mill in my garden!

      P.S. Aw thanks! That would be great. I hope you are enjoying asking questions and the live chats-I’m having loads of fun!
