Fusion

US scientists announced a breakthrough on fusion energy on Tuesday (Dec 13), potentially a step [blank] one day harnessing the process that fires the sun to generate carbon-free electricity as the world struggles with climate change. So, will fusion help fight climate change? Potentially. Besides vastly ramping up the energy [blank] fusion reactions, scientists need to produce them multiple times per second on a constant basis. Scaling that process up to a power plant and building plants big enough to cover a significant chunk of the world's growing electricity demand would take momentous efforts requiring materials, land and clear regulations for industry. Politicians supporting the existing fuels and infrastructure may be resistant to rapid change. As the quest [blank] fusion energy develops over a decade or potentially much longer, countries should continue aggressive moves into wind and solar power, energy storage, including batteries, next-generation fission power and other alternatives to [blank] dependence on fossil fuels, scientists and environmentalists say.
