If we used renewable resources within time all the nonrenewable resources we used would be replenished. I also think this would be the right thing to do because, for example if we used solar or wind energy we wouldn't waste energy as much as we do now days.
However if we were to use this. The cost for using renewable energy would be money. These days solar energy is very expensive, if we were to start using it we would spend a lot of money. Another thing is we would have to make sure that we are storing some energy in case the weather conditions are bad. (solar energy)
