Smart City Environment and Energy

Uncover the environmental impacts of smart city technology

For a smart city to live up to its name, using technology to foster sustainable growth is essential. Cities must push toward a wiser use of resources, from implementing sensors that detect leakage to using behavioral economics and gamification to encourage citizens to make thoughtful decisions on resource use.

Case studies

Take a closer look at how cities, agencies, and companies around the world are implementing these smart city environment, energy, and sustainability strategies.

Copenhagen has installed a growing network of wireless streetlamps and sensors. LED streetlamps brighten when vehicles approach but dim after they pass. The city aims to be the first carbon-neutral capital city by 2025.

The sensor-enabled light fixtures will also serve as a means of capturing data and coordinating services. For instance, the same sensors will alert the sanitation department to empty trash cans. Further, sensors can sense a bicyclist coming and shed extra light for safety as the cyclist transverses road.

Alex Laskey and Dan Yates created a company, Opower, with a single goal in mind: to use the power of behavioral economics to motivate people to save energy. They created a customer engagement platform designed to help electric utilities deliver more energy efficiency programs to their customers. Opower’s primary products are home energy reports based on user data and behavioral science principles. The company uses a mix of utilities data on user consumption patterns as well as crowdsourced data from energy users themselves. Its online scoreboard encourages friends to discuss and compare their household electricity use.

Opower then gamifies the experience by allowing energy users to complete challenges, participate in groups, and earn points and badges tied to reduced energy use. Using data from these interactions, Opower constantly tweaks its processes to keep energy users engaged. The company now partners with more than 100 utilities and claims that its model generates energy savings of two to four percent, translating into hundreds of millions of kilowatt-hours saved.

Gravity Recovery and Climate Experiment (GRACE) mission, launched in 2002, uses two spacecraft to map variations in the Earth’s gravity field. The gravitational research is, in part, collecting relevant agricultural data on factors such as groundwater availability and stress as they relate to global agricultural production areas. Maps developed using the GRACE data can identify the difference between climate-related drought conditions and the depletion of aquifers through groundwater extraction that exceeds recharge.

However, currently, this information is typically only available in specialized scientific journals. By making this information more available to farmers, the Internet of Things, drawing on GRACE as a sensor, could help farmers make more efficient and effective use of water resources.

Recyclebank has turned recycling into a game: By recycling, households can earn points that can be redeemed for real prizes, such as vacations and discounts on products from hundreds of companies. The number of points earned by each household is calculated by a radio-frequency identification device (RFID) sensors on recycling bins. The sensors record how much waste each household recycles. The more you recycle, the more points you get.

The company rewards with additional points if households complete interactives, slideshows, and quizzes related to recycling hosted on the company’s website. In just a few short years, Recyclebank has gone from an interesting idea to a company operating in hundreds of cities, with a membership of more than four million households.

Internet of Things applications promise to make conservation campaigns even easier and more effective by tracking progress and offering—or even automating—new ways to conserve. Simply giving consumers more insight into when or where they use water and how they compare to neighbors can encourage conservation, as the Municipal Water Department in East Bay (California) recently demonstrated.

Partnering with WaterSmart, the department saved five percent in water consumption by giving 10,000 customers access to a web portal that showed how each stacked up against families of comparable size, as well as by providing ideas for improving water conservation.
