1.Has only recently been tapped as a usuable source of energy
2.Is a type of renewable energy source that does not damage the environment
3.Is limited by its location- sources only occur in areas of the world that have volcanoes
-The downsides of renewable energy are that
1.They are difficult to generate power on the same large scale as  fossil fuels
2.Building wind farms and dams can disrupt wildlife and migration patterns, leadind to ecological destruction
3.Both solar and wind energy can be intermittent, only generating power when the sun is shining or when the wind is blowing

While non-renewable resources will run out after use

renewable resources are not very efficient in producing energy in larger scales but non-renewable resources are known for their efficiency in producing energy.

renewable resources have a higher maintenance cost compared to non-renewable resources]]> 2019-02-12 13:13:27 UTC https://padlet.com/Imelda/ytkiainb6ey5/wish/330303708 https://padlet.com/Imelda/ytkiainb6ey5/wish/330364981 1)Energy is unlimited. 2)There are 8 types of powers which are solar power, wind power, coal power, water power, oil power, wood power, nuclear power and geothermal power (not in any order) 3) I also learnt that there are different types/sources of energy.
