Wind power is a key component of renewable energy utilisation. Implementation of building integrated wind turbines contributes positively to the environment as a climate change mitigation option.

The sun is a powerful energy source, and even though we are not able but to collect a fraction of this energy, yet harnessing this power by installing solar panels can make a significant difference to the planet.

Increase the number of ways of accessibility throughout the city which reduces traffic congestion. Not only that, it also decreases the risks of accidents to cyclists, benefits their health and less emission of pollutant to the air.

Public transportation contributes to a healthier environment by improving air quality and reducing oil consumption, and through better land-use policies. It also helps to expand business development and work opportunities. And, it is critical for emergency situations requiring safe and efficient evacuation.

As the world's population has increased, particularly in urban centers, cities have turned increasingly frequently to underground transportation systems to help solve problems of traffic congestion, noise and air pollution, and densely built-up urban areas.

Green Vehicles are the solution to overcome from air pollution at certain level. A green vehicle, is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels.

The street facilities in the city is powered by solar energy such as street lights and bus stops because it allows reduced dependence on conventional energy, conservation of energy and less reliance on the national grid.

Benefits of vertical farming include the creation of a sustainable urban environment that encourages good health for all who choose to live there; new employment opportunities, fewer abandoned lots and buildings, cleaner air, safe use of municipal liquid waste, and an abundant supply of safe drinking water.

Helping cities better protect nature by managing their stormwater runoff, which is one of the fastest-growing threats to our waterways. During a rainstorm, water washes over roadways, collecting dirt, oil and debris which flushes those pollutants into our sewer systems and, ultimately, our rivers and oceans.
