My model is of a rentable bike rack. It’s use is to encourage the people to ride bikes and save on fuel and cut down on emissions. Alana and her mom use the bikes a lot because they cannot afford a car. 
This is an example of a solar bikeway in an effort to provide more sustainable living in larger cities such as Caracas. Since bike lanes and solar panels are about the same width, the perfect opportunity arises to place solar panels on the existing roadways. The integration of solar panels from an oil-dominant economy can provide infrastructure job opportunities and diversify the economy.
This is our local bus stop, here awaited all the people who are trying to go to work. We drive our cars to a local parking lot and we board the bus here. The most common transportation method in Urban Brazil is the bus so as seen in the image there are a lot of people waiting. IF everyone drove their car it would be a mess and a giant cluster and clog
This is the fire department of Havana, Cuba and it has been updated by adding solar panels so the fire department will be powered by clean energy.
Despite Honduras’s long history of having unreliable and unsafe transportation (changing bus routes, regular hijacking and armed robberies of vehicles, etc.), in 2041, the city of Tegucigalpa is taking matters into its own hands and starting by improving the bus stops around the city. This bus stop is a mock-up for a safer and more sustainably run El Rey Transportation bus stop towards the outside of town. The design includes soft benches and an accessible bathroom (complete with a shower) allowing for travelers and houseless individuals to rest/ clean themselves as they need, in a safe place. The lights, security cameras, and its opening concept and location are meant to ensure that patrons are waiting for the bus or using the restroom. The bathroom, lights, and the outlets (found along the side of the benches) are all powered with solar energy collected from the panels on the roof. Additionally, the water used in the bathroom is sourced responsibly as it is filtered rainwater collected in the basin attached to the back of the bus stop. The water is collected and filtered before recycled and purified before it is sent through the pipes to be used. After it is used and goes down the drain it is filtered once more and used in the mini garden growing in the wall alcove. Currently, the majority of the plants in there are simple greenery and cannot be eaten, the goal will eventually be to have bus stops with food grown in them for the community to share. In the meantime, these new bus stops are meant to help travelers have a more positive experience, help welcome houseless community members, and do so in a way that is sustainable and efficient so that they can continue to be used for years to come without adverse affect
This is a representation of the AMA bus transportation in Puerto Rico. It has been updated in such a way that it is now electric instead of gas. This emits a portion of pollution.
The Public service I improved was a bus stop.  Again, the focus here was on small-scale agriculture.  The bus stop is designed to accommodate the growth of several plants, with many parts being made of glass to allow proper amounts of sunlight to reach within.  In practice, it is a sort of small-scale greenhouse.  Not only will it assist in agricultural efforts, but it will also serve to beautify the city, and hopefully inspire a strong sense of community.
A simple and sustainable bus stop. On top of the bus stop are native plants and solars panels. The plants will help to filter air and benefit a green transition, the solar panels are used to power the stop and then send excess energy to the main grid. Inside the stop, we have 2 benches, recycling bins, and a water fountain. On the sides of the stop, we also see two moveable solar panels collecting excess energy.
This is one of the local fire stations located in Juan’s neighborhood on the outskirts of Mexico City.  The fire station made upgrades to be more sustainable in 2041 with the edition of several solar panels on the roof, as well the fact that the fire trucks were upgraded to hybrid fire trucks in an attempt to limit fossil fuel use.
This is a futuristic bus stop, built by yours truly Micheal Johnson. I’ve inserted air conditioning as well as benches to make the wait for the bus a comfortable one.
Transported by trucks from the farm/homestead, the crops are now stored in a warehouse on the Argentinian border. Here they will be loaded onto freight trains to be transported to other Argentinian cities and ports. They will be consumed domestically or shipped abroad on the international market; particularly to the US, China, and Brazil. The money made is used to stimulate the Argentinian economy and lift up impoverished people.
The mass public transportation system will be run on solar energy. Solar panels are on the roof of the bus. Bus stops will be all around the city to make sure each citizen has access.
This model is a school in Texas that runs solely on solar power.

This Firehouse located in Panama City, Panama has adapted to its current times to continue operating in a more sustainable way. We can see the green wall that is growing on the firehouse naturally, although it is maintained otherwise it gets out of control. We are also able to see the solar panels on the roof of the firehouse. This is how the firehouse gets its electricity and how they charge their electric fire trucks.
Santiago is home to a variety of public service systems. Near Maddy’s house, there is a large bus station that provides public transport. This allows for there to be less air pollution in the area, clear roadways, and economic benefits to the community. Public transportation overall benefits the environment by improving air quality, reducing oil consumption, and allowing for the creation of better land-use policies. There is also a wide range of bicycle lanes available in the area. There are bicycles for rent available as well. This allows for people to completely remove gas-vehicle transportation altogether. There are also large sidewalks that allow people to walk with ease in Santiago. This not only keeps the planet healthy but people physically healthy as well. 
This is one of the more frequently used bus stations in Asuncion and it has been made more sustainable by adding more green space, having solar panels, and the addition of electric buses.
The buses that run through the community have solar panels and charge the batteries for the bus to run. Rather than using gas and sending toxic fumes from fossil fuels in the air my bus is good for the environment. El Salvador is a very sunny place and it’s not a hassle for my bus to get a charge whenever it’s needed!
