Virginia solar volunteers bring relief from heat, and energy costs, to horse farm

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.

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.

Solar power is a great advancement for renewable energy, but traditionally relies on connecting to a grid in order to function correctly. So when hurricanes hit Puerto Rico, even those with solar panels lost access to electricity. A micro-grid offers an alternative solution, however, by relying on battery power.

Innovative mine reclamation projects across five states in the Appalachian region allow local organizations, schools, and businesses to clean up and utilize abandoned mine land. From a school that's transforming abandoned mine land into a field of solar panels to a housing development project that uses abandoned mine federal grant money to build affordable and energy efficient housing, the Appalachian region is using a comprehensive approach to renew blighted mines.

Thanks to increased awareness and public pressure, Turkey has shifted from culling street animals to catching, neutering, and vaccinating them. Following social media campaigns and the work of activists, Turkey's government has changed its policies. Today, instead of being poisoned, street dogs are treated and tagged by animal welfare teams funded by the state. The vaccinations help reduce the risk of diseases like rabies, while neutering the animals avoids the use of chemicals potentially harmful to humans.

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."

For years, a rancher in Southern Oregon has been trying to keep a local pack of wolves from killing his livestock, and after many rounds of trial and error and collaborative efforts, a high-tech fence may be the solution. Although the fence isn't cheap, many came forward to help make this a possibility and show their support for a project that united people that historically have stood politically opposed.

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.
