What are tree common challenges in managing nonrenewable resources?
How can we make them last longer? How can we distribute them fairly? How can we find more coal, oil, and natural gas?
Challenges for using alternative renewable energy resources include:
* producing enough wind and solar energy to make them financially efficient
* storing excess energy to use when needed
* producing biomass resources that don't pollute or take needed food products away from the hungry.
