  • The Cost of Going Solo in Solar

    Three decades. That is how much time is left to decarbonize the world’s energy systems to limit global warming to 1.5°C, according to the latest Intergovernmental Panel on Climate Change (IPCC) report. Achieving this feat requires renewable energy systems be deployed at an unprecedented speed and scale. While daunting, however, the good news is that this transformation may not cost as much as many expected just a decade ago, thanks to rapid cost declines in renewable energy technologies.

  • Responsible Research Won’t Be Enough to Control Solar Geoengineering

    Guest Contributor  //  July 12, 2022  //  By Whit Henderson

    As climate change worsens, the once-unimaginable power to use technology to cool the planet—a method known as “solar geoengineering”—has quietly entered the realm of possibility. Yet the prospect of developing such planet-altering technologies has launched an intense debate: Can this be achieved responsibly? Should it be attempted at all?

  • Could Renewable and Nuclear Energy Be the Key to Fighting Climate Change?

    “Today we face two existential threats: nuclear annihilation and catastrophic climate change,” writes Daniel Poneman, former Deputy Secretary of the Department of Energy, in his book, Double Jeopardy: Combating Nuclear Terror and Climate Change. “Both stem from human origins. We need to fight both threats aggressively.” At a recent event hosted by the Wilson Center, Poneman discussed his book. While the dangers of nuclear energy are clear from incidents like Fukushima and Chernobyl, Poneman proposes policies that aim to encourage a safe, non-carbon baseload power that responds to the Intergovernmental Panel on Climate Change (IPCC) 2018 report and keeps our global temperature rise below 2 degrees Celsius above pre-industrial levels, per the 2015 Paris Climate Agreement.

  • Coal Communities Struggle to Diversify

    Blanketed by freshly fallen snow, mountains of the Teton Range loomed above as I explored the picturesque town of Jackson, Wyoming. A native Bostonian, I had no experience in the heart of the country, but that week I wasn’t the only outsider wandering Jackson’s icy streets. In November 2018, experts from all over the world gathered in Jackson to attend the Jackson Hole Center for Global Affairs Forum with one common goal: to identify the challenges and opportunities for coal communities worldwide as they transition their economies away from coal.

  • Chinese Solar Shines at Home and on the Road

    China Environment Forum  //  March 7, 2019  //  By Margaret Jackson

    For solar industry professionals in China, May 31, 2018, is a day that will live in infamy. At the beginning of 2018, Chinese domestic solar developers were riding a high after reaching a record 53 GW of newly installed solar capacity the previous year. Most sources projected this breakneck pace of new solar construction would continue through 2018. On June 1, 2018, however, the National Development and Reform Commission, Ministry of Finance, and National Energy Agency announced a new policy to lower the solar feed-in-tariff, halt subsidized utility-scale development, and implement a quota for distributed projects. Industry professionals refer to the infamous policy as “531” for May 31, 2018, the day that the solar industry ground to a temporary halt or “freezing point.”

  • The Dark Side of the Sun: Avoiding Conflict Over Solar Energy’s Land and Water Demands

    ›
    October 2, 2018  //  By Olivia Smith

    The 73-megawatt Lopburi solar power plant in central Thailand is the largest solar photovoltaic project in the world.  It will be central to Thailand's efforts to generate  energy from renewable sources.

    Solar farms—just like regular farms—cover large swaths of land, requiring between 3.5 to 16.5 acres per MW of generating capacity. The largest solar plant in the world, the 648 MW Kamuthi facility in Tamil Nadu, India, covers ten square kilometers. But it will be dwarfed by the 3,450 MW facility under construction on China’s Tibetan Plateau, which will span 298 square kilometers when completed. Building these large plants requires fundamentally changing how the land they sit on is used, which—without careful planning—could have negative impacts on the environment and local communities that could potentially lead to conflict. The backlash could not only derail solar projects, but could also fuel resistance to future renewable energy development.

  • Energy Innovation in Remote Arctic Communities

    Energy

    Without connections to wider electrical grids, communities in the remote, rural Arctic depend on diesel generators for power—which makes electricity “ten times more expensive” than in the rest of Canada or the United States, said Martha Lenio of the World Wildlife Fund-Canada Arctic Team during a recent Wilson Center Ground Truth Briefing. In addition, spilled diesel “can harm wildlife, impact food and water security, and compromise permafrost integrity,” said Lenio. These challenges have led some communities in the Arctic to seek cheaper, safer, and more innovative energy solutions, said panelists during the briefing organized by the Wilson Center’s Polar Initiative and Canada Institute.

  • Indian Military Recognizes Environment as “Critical” Security Issue, But Response Is Still Fragmented

    For the first time, the Joint Doctrine of the Indian Armed Forces acknowledges that the “environment has emerged as a critical area of the security paradigm,” and warns that if environmental degradation and related issues increase security risks, the military will need to respond. Released in 2017, the doctrine lists a series of non-traditional security challenges linked to the environment that could influence conflict and war, including “climate change, ecosystem disruption, energy issues, population issues, food-related problems, economic issues of unsustainable modes of production, and civil strife related to environment.” While the military has taken steps to address its impacts on the environment, it can do much more to support the nation’s environmental goals and mitigate environment-related security risks.
