Swedish technology could make geothermal as mainstream as wind and solar

Austria rolled out the KlimaTicket, an annual pass that gives the holder access to all forms of public transportation in the country, to encourage increased use of public transport with an eye toward climate change mitigation. The uptake has exceeded expectations with 134,000 tickets sold within just the first two months, but it's still unclear what effect the program will have on the country's carbon emissions.

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

With the prices of solar technology dropping and the opportunity to save drastically on energy usage and costs, businesses and organizations across the country are investing more in solar infrastructure for their buildings and facilities. The Better Buildings Initiative of the US Department of Energy is helping by providing guidance and documenting effective approaches and financing for renewables installations - from hotels, to schools, to big box retail.

The University of Nevada at Reno’s DeLaMare Library houses a ‘maker space’ which houses creative tools ranging from whiteboards to laser cutters to microprocessors. It is the library’s hope that this space allows students and the general public to fabricate their ideas and form new, innovative collaborations.

A weatherproof tent for homeless families performed well in a pilot, winning design awards and public praise, even before becoming commercially available. The tent requires no tools to set up and can fit two adults and three children. For one family, it was their first home together after six years of living separately in single-gender shelters.

Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

Virtual reality is being used as part of medical education providing a way for nurses and other medical workers to better understand how a patient may experiencing their surroundings. Virtual reality modules have been created for blind, colorblind, dementia, and dying patients.

Math requirements are a common barrier preventing students from successfully graduating from community college in Washington state. Schools are offering a new way for non-STEM majors to earn the credit; Statway teaches students accessible statistics mixed with real-world examples as an alternate to the traditional algebra-precalculus trajectory.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."

Solar energy is a clean, cheap, renewable, and land-efficient resource, making it a valuable technology to scale up in the face of climate concerns and clean energy. Diversifying the supply chain for creating and sourcing solar panels can help make solar energy more reliable when faced with geopolitical and human rights issues.
