An ideal sustainable city would have to have many factors. First off, fossil fuels have to come to an end for the city to be sustainable. This would impact many things including means of transportation, construction/road work, daily household items like the air conditioner or heater, and refineries/factories. Another change would be sustainable farming and food supplies. Because agriculture is mainly seasonal I would recommend an “indoor farm” where we can simulate the conditions needed for higher demand foods as well as increase the space because we could expand vertically. A third change would be and a very important change would include sustainable energy. As I covered earlier we need to get rid of fossil fuels and other harmful ways to acquire energy. Some new ways that would be widespread throughout all of the community would be 1. Solar energy; solar energy is an amazing and simple way to get electricity from the sun without harming the environment. 2. Wind turbines; wind turbines are also a very nice and simple way to acquire energy by using wind to spin and create electricity. 3. Hydroelectric power; Hydroelectric power is the same concept as a wind turbine where instead, the water pushes the blades instead of wind. These are the cheapest and some of the most sustainable ways for humans to harness energy and use it for themselves.
