Simple tech could store energy by lifting and dropping giant bricks

We’ve previously written about how gravity can serve as an incredible ally in our quest to find viable solutions to storing excess renewable energy. Now, using a similar principle, Swiss startup Energy Vault has come up with a simple technology that can collect excess energy by lifting giant Read More...

Thought Leader Series: Julian Spector on Hawaii's renewable future

This Thought Leader Series piece was originally published in Canary Media's August 19, 2021 Newsletter. BY Julian Spector Last week I visited Oahu, Hawaii's most populous island, which is currently girding itself for the closure of the state's last coal plant. My mission: to figure out how Read More...

Solar power in Australia overtakes coal for the first time

Coal plants are some of the largest contributors to the energy sector’s hefty environmental footprint. Transitioning the sector away from these dirty fossil fuels can go a long way in helping us become a carbon-neutral world. While Australia still has a considerable number of coal plants, Read More...

This device combines solar and human energy to generate electricity

An average person creates 100 to 150 watts of power while riding a stationary bike. That energy, however, usually remains untapped, causing users to miss out on a great opportunity to generate their own green electricity. In fact, by harnessing the biomechanical power generated by a stationary Read More...

Volvo will soon use fossil-free steel to make its electric trucks

Earlier this year, Volvo pledged to go all-electric by 2030, while making its entire business operations (including its supply chain) climate-neutral by 2050 — all in a bid to do its part in the fight against the climate crisis. To that end, the carmaker has recently made a deal with Swedish Read More...

New tidal energy design harvests double the energy from ocean waves

Tidal energy could soon hit record conversion efficiency thanks to a new development from scientists at Australia’s RMIT. The engineers have developed a novel design for a convertor that they claim operates with far greater efficiency than current systems. They hope the breakthrough could pave Read More...

Remote Northern Ireland island aims to become carbon neutral by 2030

A UK island has just committed to becoming carbon neutral by the end of the decade. Lying six miles off the coast of Northern Ireland, Rathlin Island has only been connected to the electricity grid since 2007. About 150 people live on the island and they want to produce their own wind and wave Read More...

California’s new energy codes push an all-electric housing future

As more cities embrace natural gas-free futures, the US’ most populous state is giving the concept of all-electric homes a big legislative push. California has approved new energy codes that will incentivize electric appliances and efficient heating and cooling systems. Approved by the Read More...

The Optimist View: Building Circularity into Electric Vehicles

To eliminate the concept of waste means to design things-products, packaging, and systems-from the very beginning on the understanding that waste does not exist.  - William McDonough BY Kristy Jansen and Sam Suh Earlier this year, I became the proud owner of an all-electric car一a used Read More...

The world’s first all-electric tugboat to put to sea in 2023

According to the International Maritime Organization (IMO), maritime transport emits around 940 million tonnes of CO2 annually and is responsible for about 2.5 percent of global greenhouse gas (GHG) emissions. As engineers are working to green up cargo ships with the help of low-carbon fuels, Read More...
