There’s still a long way to go, but it’s an important milestone.

Ten years ago, solar and wind didn’t even make up 1% of our global energy mix. Now, in just a decade, they’ve reached 10%. It may not seem like much, but becoming such a significant part of the global energy mix in such a short time is remarkable — though there’s still a long way to go.

The past couple of years have been horrendous in more ways than one, but that doesn’t mean all is bad in the world. In fact, renewable energy continued its impressive growth, according to research from Ember, a climate and energy think tank.

This doesn’t mean you need to don an ushanka and start marching. You can start taking collective action by focusing on community groups and connecting with climate leaders. This will likely help you solve other issues, too, like waste disposal, recycling, and community clean-up projects in your locale.

Conclusion

Combating climate change requires all of us to reconsider our individual and collective climate responsibility. As an individual, you can do your part and let others know what you are doing. It has never been easier to connect with the world and share than it is today. You can join others in writing letters to the editor of your local newspaper, or your local and national government representatives. You can join groups like Citizens’ Climate Lobby and learn how to engage policy decision-makers. And in your daily routines, you can lead by example.

Flooding is common in informal settlements in Bwaise, a neighbourhood in the Ugandan capital Kampala. Bwaise’s residents are largely excluded from planning and local decision-making processes, and have poor housing and limited access to sanitation and other essential services.

The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.

Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.

The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.

Every industry will be affected by quantum computing. They will alter the way business is done and the security systems in place which protect data, how we battle illnesses and create new materials, as well as how we tackle health and climate challenges.

As the race to build the first commercially functional quantum computer heats up, here we discuss a handful of the ways quantum computing will alter our world.

The Charles M. Schulz Sonoma County Airport had two solar power systems installed onsite and made them live in February. Over the course of their electricity-generating life spans, they will offset thousands of tons of CO₂ emissions and potentially save millions of dollars.

Sonoma County has been hit particularly hard by wildfires in the last several years. These natural disasters occur with some regularity on their own, but many believe the latest ones are connected to the effects of climate change. The county has been experiencing higher temperatures and droughts as well. As a result of these challenges, Sonoma County’s government set a goal for the county to be carbon neutral by 2030. The airport solar power installations fit within the carbon-free plan. (The California state government has a goal for California to be operating on clean, carbon-free electricity by 2045.)

Jon Stout, the Sonoma Airport Manager, and Rachel McLaughlin, ForeFront Power’s Vice President of Sales & Marketing, provided some insights to CleanTechnica about the new solar power systems. (The last three answers are from ForeFront.)

The classic arcade game Cyclone has attracted many players, along with their coins, thanks to its simple yet addictive gameplay. In its most basic form it consists of a light racing around a circular track, which the player then has to stop at exactly the right place. Arduino enthusiast [mircemk] made a home version of this game, which allows addicts to keep playing forever without running out of quarters.

Instead of an arcade cabinet, this smaller version has an upright 3D-printed ring that holds 60 WS2812 LEDs. A further six in the center of the ring act as a score counter. An Arduino in the base drives the LEDs and runs the game, which is based on an earlier iteration built by [oKeeg]. An interesting addition is a large homemade “arcade button”, which is large and sturdy enough to withstand any abuse inflicted on it by a frustrated player.

Engineers at the University of Cincinnati have developed a promising electrochemical system to convert emissions from chemical and power plants into useful products while addressing climate change.

UC College of Engineering and Applied Science assistant professor Jingjie Wu and his students used a two-step cascade reaction to convert carbon dioxide to carbon monoxide and then into ethylene, a chemical used in everything from food packaging to tires.

“The world is in a transition to a low-carbon economy. Carbon dioxide is primarily emitted from energy and chemical industries. We convert carbon dioxide into ethylene to reduce the carbon footprint.” Wu said. “The research idea is inspired by the basic principle of the plug flow reactor. We borrowed the reactor design principle in our segmented electrodes design for the two-stage conversion.”
