#14 - Innovations that push the boundaries of fossil free energy

Hello! Today: Climate change and keen competition are the main driving forces behind more sustainable and efficient energy solutions. And only innovations that offer both can last long-term. In this issue, THE EDIT explores the four elements in search for innovations beyond traditional renewables. Plus: High-flying plans for flight, deep-diving drones, and the importance of digital twins.

Four technologies that could reshape the future of renewable energy

What to know: With global demand for fossil-free electricity set to double in the coming decade, the need for new solutions is intensifying. Could innovations such as space-based solar reflectors, algae biofuels, sand batteries and high-altitude wind turbines soon become viable options for the energy sector?

Why it matters: Innovations are catalysts for change, pushing societies to redefine what is possible. Pioneering solutions like these, which explore novel ways of utilising the natural elements – sun, air, earth and water – are crucial for driving progress in the energy sector and reduce our reliance on fossil fuels.

3 x quick updates from the energy world

The balcony boom

Germany has long been one of the leading nations in terms of generating solar power from residential homes, especially rooftop panels. Now, the government is encouraging people to install solar power on their balconies. (euronews.com)

A heat pump revolution

Air conditioning units in the windows of brownstone houses and skyscrapers have been one of the iconic features associated with New York. However, they may soon be replaced by heat pumps. (wired.com)

Final countdown for coal

For much of the 20th century, coal was the United Kingdom's primary source of electricity production. But over the past 20 years, coal power stations have been shut down one by one. Now it is time to say a last goodbye. (theguardian.com)

And finally...

How footsteps reduce CO2 footprint

Small kinetic movements can have big energy effects, as shown by a pioneering energy project in Paris. A system engineered by students from the Junia Graduate School of Science and Engineering, which converts turnstiles into mini turbines, utilised the movement of 27,000 daily commuters to generate electricity. This technology could potentially reduce Paris´s CO2 emissions by 30,000 tons annually.
