  • The Hottest Amenity From Developers? A Power Plant Made of Batteries.

    An apartment complex in Utah includes a solar battery in every apartment allowing the resident, power utility, and building developer to save costs for generating electricity. Through a unique partnership, the power systems can provide 12.6 megawatts of power for the building, which translates into residents saving up to 40 percent on the energy bills. This setup might not be easy to scale, but the developer plans to expand the model in other states.

  • It looks like the Batmobile, works on solar energy, and could be the future of cars

    Aptera Motors, a California-based startup, is poised to roll out the first mass-produced solar vehicle this year: for $25,900. The car is a three-wheel, aerodynamic electric vehicle covered in solar cells that can provide energy to drive about 40 miles. The model is not 100 percent efficient with some energy lost in its electrical current conversion and in its drive system, but the creators say it is four times more effect than an average electric vehicle. Still, when the company started taking preorders, they sold out of its first 330 vehicles in 24 hours.

  • Electric car batteries with five-minute charging times produced

    Batteries that can be fully charged in five minutes have been created for the first time, allowing electric cars to recharge faster. The Israeli company StoreDot produced 1,000 of these new lithium-ion batteries, which can be recharged for 1,000 cycles while retaining 80 percent of the original capacity. It could be a few years before they are mass produced, but the CEO of the company says that this feat “demonstrates it is feasible and it’s commercially ready.”

  • How sunshine can make the railways greener

    As a way to reduce the amount of diesel fuel that powers trains, governments and transit companies around the world are turning to solar panels as a way to utilize renewable energy. In Australia, a solar train launched in 2017 that uses lithium-ion batteries that are charged by solar panels on the roof of the carriages. And a rail line in the United Kingdom uses energy from a solar farm to keep the train running. Scaling solar panels for nation-wide transit systems can be challenging, but many countries are committed to eliminating the use of fossil fuels on their rail networks.

  • A pollution solution where the rubber meets the road

    The Tyre Collective, a project by four recent graduate students in London, is seeking to capture vehicle tire pollution, the microplastics that go into the air from the friction of tires. They have been developing a device that attaches to the bottom of a car and uses electrostatic charges and airflow to collect up to 60 percent of tire particles as the car is driven. To reduce the amount of tire pollution, tire companies are seeking to balance safety requirements, tire durability, and making them out of more sustainable materials.

  • The revolutionary boat powered by the ocean

    Since the Philippines relies on boats to transport people and goods across the island nation, a shipbuilding company is designing a new low-carbon alternative of the bangka — a traditional Filipino boat — that uses the waves of the ocean to power it instead of fossil fuels. The ship, known as the trimaran, uses wave energy that converts into electricity for the ship. However, a typhoon and the COVID-19 pandemic have delayed the project, and there are also cost and design challenges. But the trimaran’s use of wave energy could be a step toward reducing the country’s greenhouse gas emissions.

  • A New Weapon Against Climate Change May Float

    Floating wind turbines off the coast of Portugal is one of the latest experiments to convert wind energy into electric power. These machines can generate electricity for a city of up to 60,000 people. While it will take more financing and time to scale the project, investors are impressed with the results and see it as a viable financial return to combat climate change.

  • This Philly-made "fruit hacking" tool fights food waste and saves farmers thousands

    Monitoring spikes in ethylene allows produce distributors to reduce food waste. The Philadelphia based company, Strella Biotech, uses sensors and the Internet of Things (IoT) to track when produce begins to emit ethylene and ripen. By paying closer attention to the status of their produce, distributors partnering with Stella Biotech have reduced food waste and saved money in the process.

  • Wildfires and blackouts mean Californians need solar panels and microgrids

    Localized, distributed energy systems are popping up around California. As the larger electricity system becomes less reliable in the face of wildfires, more individuals are turning to microgrids and solar energy with help from organizations like Clean Coalition and Stone Edge Farm Microgrid. While still happening on a small scale, such energy systems may become more popular as its sustainability in a changing climate shows to be more resilient.

  • Step by Powerful Step, Citizens Lead Puerto Rico into Its Solar Future

    After Hurricane Maria hit Puerto Rico, knocking out power across the country, solar energy has stepped in to be a sustainable possibility. Such efforts have included lobbying local legislatures to incentivize communities to create their own solar project and training residents to install solar panels on their own. Many of the solar initiatives that have started have been community-led and hyper-local, meaning that what many deem a basic right – access to energy and electricity – are more accessible than ever.
