A Utopian city or world is a world where there is no sickness, violence, death, war and misery. But those events are inevitable, well most of them are. However the world would be better if people use less energy. Think of it this way, you need to pay less money if you save energy and you also get to live longer. And not just energy, sources as well. Recycle paper to save trees, they give us oxygen. Recycle plastic, some animals mistake them for food and if they ate plastic they would die of suffocation or toxic. A lot of countries are using solar, wind and water energy. But a lot is not enough, make it all. Remember, there is limited energy in the world, use it wisely.
