Solar Cost Hits World’s New Low
“Chile awarded a contract to sell solar power for $29.10 per megawatt hour (MWh), the lowest ever across the planet. This surpasses the record set in May of a $29.90 per MWh bid in Dubai for an 800 megawatt (MW) solar project. “
Five ways cities are acting on climate
Cities aren’t waiting for the rest of the world to make huge strides in confronting the climate crisis. In December 2015, almost the entire world (195 nations to be exact) agreed to reduce their greenhouse gas emissions and do their part to solve climate change as part of the landmark Paris Agreement. After years of negotiation and discussion, the world is closer than ever to finally shifting away from dirty fossil fuels and working together to reverse the dangerous upward trend in warming global temperatures.
Farming Solar Power in the Cosmos
What was then an implausible idea—collecting solar energy in space and sending it to Earth—is now the goal of scientists around the world, marking a new space race that could end reliance on dwindling fossil fuels, fundamentally shift power in the geopolitical conflicts they have sparked, and meet the rising demand for energy from the developing world. Paul Jaffe, a spacecraft engineer and principal investigator at the U.S. Naval Research Laboratory in Washington, D.C., has brought the U.S. closer to that goal with his work on space solar technology, which has drawn international attention—and for good reason: The innovation would have a profound impact on humanity.
What If All U.S. Coal Workers Were Retrained to Work in Solar?
The global economy is in a massive transition from a fossil-fuel-based energy system to one using sophisticated renewable energy technologies. For tens of thousands of fossil fuel workers, though, the energy industry outlook is not promising. For coal industry workers, the future looks particularly bleak. However, research I conducted with Edward Louie of Oregon State University offers hope for a better future based on retraining workers. Our study (published in the journal Energy Economics) quantified the costs and benefits of retraining coal workers for employment in the rapidly expanding solar photovoltaic industry—and it explores different ways to pay for this retraining.
