Rikers Island, the world’s largest penal colony, could become a solar farm. While this is a significant step toward a healthier future, certain considerations must be taken into account to ensure the transition is just and equitable.

The zero-carbon energy transition is the solution to the 2022 energy crisis and a fundamental part of the solution to the global climate crisis. Two new reports not only identify the main roadblocks to investment in renewables, but also provide actionable recommendations to governments.

Decarbonization is largely unpredictable, but there are some elements we can predict.

Increasingly extreme weather has the potential to derail renewable energy projects — but there are a few things we can do to keep moving forward.

Some environmental groups are prioritizing local, smaller-scale conservation over the critical goal of combatting global climate change.

While fossil fuels will be needed for a generation as we transition to renewables, they will ultimately be driven from the marketplace by price, pollution, and the performance of renewable energy.

A new study analyzes the impacts of climate change and variations in water availability on the hydropower sector, a key source of cost-effective renewable energy for many countries around the world.

As the nation moves toward decarbonization, it will be challenging to produce enough renewable energy to meet the increased demand for electricity. What’s standing in the way?

Better renewable energy technology will make greenwashing an idiotic strategy, and audited disclosure rules would make carbon-related greenwashing illegal.
