   It’s not that hard to visit wikipedia to get information for homework answers rather than having other people do it for you.

   I am glad you are interested in this question because it is important that we should reduce our reliance on non-renewable resources. Future generations will not thank us for wasting such resources.

   Coal and oil are examples of non-renewable energy sources. They are fossil fuels obtained from the ground and were created millions of years ago during a phase in the earth’s development that is over. So as we use these resources less is available for the future. Furthermore burning fossil fuels creates pollution.
   Solar panels and wind mills are examples of renewable resources because collecting such energy has little or no impact on its availability for the future.

   But it may be worth pointing out that the term "renewable" is confusing. What we really mean is "sustainable".

   Best wishes for a more sustainable future.

   Building slightly on the last answer: Yes renewable technically refers to materials such as wood. so wood burning, is renewable energy because the stock is being renewed all the time…however when to take into account pollution and so forth it doesn’t really present itself as a ’sustainable’ energy source. But I imagine the answers you are looking for are
   renewable = solar, wind, hydro
   non-renewable = coal, crude oil (in it’s various forms)
   Now nuclear power is a questionable one. The power itself is sustainable…but to produce so much in the way of toxic byproducts mean it shouldn’t really be considered as an alternative to non-renewable sources. But that’s more of an eco issue than an answer.
