In the fight against climate change, wind and solar power have always held the greatest promise. Despite their ability to offer clean and plentiful electricity, the high cost of installation and the variable nature of their generation have always been a challenge.
In late February, a bipartisan group of 17 governors signed the "Governors' Accord for a New Energy Future," a joint commitment to take action to promote clean energy, clean transportation choices, a modern electrical grid, and a plan for a new energy future.
Separated from the U.S. mainland’s electric supply by an ocean, Hawaii is working toward a goal mandated by Hawaii’s Renewable Portfolio Standard (RPS), which requires 40 percent of the state’s electricity to be derived from clean-energy sources by 2030.
Scientists at the University of Southern California (USC) have developed an organic, rechargeable battery that could be scaled up for use in power plants, making the energy grid more resilient and efficient by creating large-scale capacity to store energy for use as needed.
