Raton, a town once surrounded by eight coal mines, now has a main street of boarded-up buildings. There is reason for optimism as the town diversifies its local economy, betting on "a mix of small manufacturing businesses, health care and specialty services, and hospitality for travelers" to endure the sudden decline in mining revenue. Its calculated revitalization may hold lessons for other towns.

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.

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.

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.

Philanthropies are funding “tough tech” startups that are developing technologies to cut greenhouse gas emissions and mitigate the effects of climate change. Since 2014, the nonprofit Prime Coalition has channeled more than $24 million from wealthy donors and foundations to 10 ventures focused on that goal. Not all of their investments, though, have paid off. Yet, some of these initial investments could lead to widespread solutions to the world’s climate crisis.

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.
