Here's your chance not just to be the mayor, but the original city planner as well! Imagine a medium sized city that would be developed with modern, low carbon transportation in mind, and other strategies to reduce the average citizens' carbon footprints.
What would that city look like? Would that make you more likely to want to live there?

comment here to help us solve some problems about sustainable cities
Problems:
- Wind Turbines = Loud, no one wants to live near them.
- Solar Panels = Cannot store energy = No energy at night
- Hydropower = Limited energy, only works on dams
- Eco-Friendly Materials = Expensive, hard to acquire
Question: Can we replace all houses with sustainable houses?
pls comment ways to solve the problems / suggest more problems we have to solve about sustainable cities
Windows facing the Sun should be coated with solar films in order to generate electricity.
Hi Ray, if we continue not use that much solar panels, it will soon die out!
creating solar panels cost a LOT of energy
Solar panels are really expensive!
Solar panels are expensive but their maintenance cost is lower than electricity. Solar panels cut back on harmful pollutants including sulfur oxides, nitrogen oxides, and pollutants as well as greenhouse gas emissions like CO2. And what some people do is that in the day they use the sunlight instead of using the solar panels. Then, when it starts to get dark the solar panels have already stored their energy from the day and they can use it at night. I have solar panel lights in the balcony in my house and that's what they do.
sorry. one of the problems i listed in the solar panels part, is wrong
turns out solar panels can store energy now.
sorry
When people are building wind turbines they usually build them in distant places where people don't usually live. They build them in areas like grasslands, places near the ocean, and mountains. Offshore wind turbines can contribute to the development of habitats for fish (turbine reefs) and other marine species.
WIND TURBINE IS EXPENSIVE. It is 4000 dollars to 8000 dollars per rated kilowatt.
I found out that there is something called concentrating solar thermal power. People build mirrors around a receiver and those mirrors reflect sunlight to the receiver to create heat and then into electricity. These things don't use direct sunlight so they can store energy when there is no sunlight or very little sunlight while regular solar panels can't. Still, people choose regular solar panels because they are cheaper.
