Transitioning to a world powered by renewable energy is key to tackling climate change. Here you can find the latest good news related to our clean energy transition, covering wind, solar, green hydrogen, hydropower, and more.
These algae solar panels generate green energy while cleaning the air
The solar panels of the future could be a lot greener (literally) than the ones currently adorning our rooftops and fields. At least that’s the vision of 23-year-old Mexican biotechnologist Adán Ramirez Sánchez, whose solar energy invention puts algae under the spotlight. Green energy from Read More...
Electric cars on Scottish island can now be powered entirely by the sea
After more than five years of powering local homes and businesses, tidal energy turbines in the Shetland Islands of Scotland are now charging electric vehicles. Car owners living on the island of Yell can now charge their vehicles using sea-generated energy harvested by Nova Innovation’s tidal Read More...
US announces measures to expand offshore wind energy production
We recently shared how the US is making progress towards its first utility-scale offshore wind farm in Massachusetts. Now, the country is ramping up wind power even further with the announcement of a New Wind Energy Area between Long Island and the New Jersey coast. The new project is part Read More...
New hydrogen fuel method also cleans up pharmaceutical waste
We recently wrote about how hydrogen power could be used to clean up commercial ammonia production. Now, another group of researchers is also exploring the symbiotic cleaning powers of this green energy source. A team of engineers has come up with a catalyst that could remove pharmaceutical toxins Read More...
New blade design has the potential to reduce wind energy costs
As an increasing amount of evidence suggests, the world could be powered entirely by renewables a soon as 2050. But to make sure that happens, we need to continue to develop new, innovative designs that will streamline the transition to clean energy. That’s exactly what a team of scientists in Read More...
This grassroots renewable energy organization is powered by local moms
One by one, more cities are banning natural gas in new construction projects. One grassroots organization leading the transition to fully-renewable in Cambridge, Massachusetts is HEET, the Home Energy Efficiency Team. HEET advocates for replacing old gas infrastructure with geothermal micro Read More...
Transparent solar cell greenhouses could grow food and produce energy
Solar power is one of the fastest-growing forms of renewable energy, so there are many initiatives that are trying to see how solar can be combined with other industries, like agriculture, to become even more effective. We at The Optimist Daily have already written about agrivoltaic farming, Read More...
Floating seawater reservoirs could help Helsinki become carbon neutral
As humans, we pride ourselves on our ability to innovate and adapt to a variety of environments. This has led us to develop technology that can support civilization, even in extreme environments. However, this technology largely relies on fossil fuels. Now, there’s a global push to put human Read More...
Microwave boilers could help cut heating emissions
Heating is responsible for 14 percent of the UK’s carbon footprint, posing a major hurdle in the country’s journey to reach net-zero emissions by 2050. As the country plans to phase out the use of gas boilers in homes by 2030, more sustainable heating technologies — such as green hydrogen — Read More...
World's first airport for flying cars launches this year
Coventry, UK is set to go down in history as the location of the world’s first airport for autonomous delivery drones and electric flying cars. The project, conceived by Urban Air Port, won the British government’s Future Flight Challenge and received a substantial grant of £1.2 million to Read More...
