Is renewable energy an important topic today? Why?

Obviously the renewable energy is transforming in a very, very important topic lately and that the whole issue of global warming and pollution, we must begin to care for the world.

To consume and consume and consume energy only do harm to the environment, animals and ourselves, we must understand once and for all that the earth is also tired. I think we should start caring for the earth and one of the best ways is to use renewable energy.
Some of the best ways to do this could be for example using solar energy, with panels like those at the movies, or wind energy or tidal energy, and would take advantage of all these things very well endless :D
A curious fact: I was looking a little information to make the post and saw the symbol of renewable energy is the sunflower that leverages much sunlight ... Is interesting, isn’t it?
