Natural resources like coal and oil are fossil fuels, which means there is a limited amount of them. After they run out, there is no more. Since we have based most of our energy needs around these two types of natural resources, what will our world do when they run out? This probably won't happen for many more hundreds of years, but it 99% of all scientists agree that it will happen. Your grandchildren's grandchildren may very well face some "Energy Blues".
Should we start working now to transition to other types of energy sources other than fossil fuels? What will happen if we wait until the last minute to make this transition? Post your comments about how we can stop the "Energy Blues" before they begin. Remember to follow the Blog Expectations. :-)
