Controversy over alternative energy
Nature is an entropy, in chaos you may say, but with the Sun it's our Universe. The Earth here around is a unique place and it's like nowhere else with ecosystems whose life takes place and gets created like by magic. It's where every part of it is important. You'll find also by the fact that you are not God, and you can't replicate or create life on Earth and you better take care of it.
When we're referring to alternative energies we are talking about an alternative energy to a previous form of energy like fossil fuel, wood, even whale oil, and nuclear. And that, for the biggest part we would prefer an alternative source of energy to the fossil fuel responsible for the poisonous greenhouse gases, health diseases, and global warming. It could be also an alternative to the scarcity of wood and the destruction of forests and the preservation of nature. It could be also that we would like to get rid of the danger of the nuclear and its nuclear wastes. All of this has many objectives and many goals like saving the trees or just to clean up the atmosphere for world health problem issues.
When we think of alternative energies, renewable energies or clean energies, we may think of them as perfect alternative solutions to fossil fuel, but it's not the case. Even those technologies have many direct and indirect effects on the environment. Some pollute also, some make noises, and they are not by far magic solutions that will solve all our problems.
