  • A Utility's Effort to Boost EV Use--Before and After Tax Credit Loss
    Feb 28 2026

    Since 2021, Public Service Electric & Gas (PSE&G), New Jersey's largest utility, has added 30,000 electric vehicles (EV) to its system, in part by offering rebates and other incentives. Before January 2026, the growth rate was double digit, but is now flat, becuase of the loss of the federal EV tax credit and changes in the market.

    Dawn Neville, senior manger of electric transportation at PSE&G, describes the program's successes and challenges. How to get more chargers installed at multi-family housing complexes? How much do demand response programs for EV drivers help out in the summer? And how might a new time-of-use rate that varies from 9 cents/kWh (off peak) to 60 cents/kWh (on peak) help save money for people who charge at home?

    About the guest:

    Dawn Neville, an environmental engineer who transitioned from working on hazardous waste sites to transportation electrification at PSE&G's EV charging program

  • How Does Floating Solar Affect Birds, Alligators and Other Animals?
    Feb 11 2026

    Elliott Steele, a researcher at the UC Davis Wild Energy Center, is now studying how a floating solar array at the Nelson Family Vineyards in Mendocino County, Calif. affects birds. He's also studying how a 6-MW floating solar array–Califronia's largest– in Sonoma County is influencing wildlife. In Florida, he says, alligators and other animals hang out on the solar systems.

    Wildlife can also affect the floating solar panels, by defecating on them, for example, and lowering the solar output.

    This is a follow up to my last podcast episode about Nelson Family Vineyards' floating solar array.

  • Vineyard's Floating Solar To Slash its Utility Costs in Northern California by About $90k/Year
    Jan 29 2026

    Nelson Family Vineyards in Mendocino County, Calif., will soon power up its floating solar system, deployed on pontoons on an irrigation pond, expecting to cut utility costs, which jumped 180% over the last three years, by about $90,000 annually.

    Researchers at the University of California Davis are studying how the system will affect wildlife–the focus of our next podcast, which will touch on how songbirds at the farm are affected by the system–and how alligators in Florida climb onto these systems.

    The Nelsons are looking into selling or transferring a 30% investment tax credit to help pay for the system.

  • These Farmers Want to Use Agrivoltaics to Supply Healthy Food to their Community
    Jan 6 2026

    Itanna and Yosafe Murphy are working to use agrivoltaics--co-locating solar PV energy production with agricultural activities on their 160-acre farm--to provide healthy, fresh and tasty food to their community, along with STEM education and energy resilience.

    In addition to agrivoltaics, the project, located in Oregon's Willamette Valley, will integrate vertical farming and hydroponics. Oregon State University, Ecotrust, the National Renewable Energy Laboratory and others have joined the effort as technical partners.

    Despite the loss of funding sources from the federal government under the Trump administration, the pair are moving forward with a "blank canvas and a really big idea," hoping to create a model for other farmers.

  • Hay Farming Doesn't Pay the Bills. Agrivoltaics Does--and Helps Address Climate Warming
    Dec 15 2025
    Byron Kominek, founder of Jack's Solar Garden in Boulder, Colo., an agrivoltaics site that attracts thousands of visitors annually, says hay farming doesn't pay the bills. But installing solar panels above crops and selling the solar to the utility is a revenue generator for the solar garden. Not only can agrivoltaics--the practice of co-locating solar panels with agricultural activities-- generate revenue, but it can also address climate warming by providing shade. Kominek educates students and community members about the benefits of agrivoltaics as director of the Colorado Agrivoltaics Learning Center. It's important to think long-term about how to adapt to climate change, said Kominek, who received an Ashoka Fellowship for his work as a social entrepreneur.

  • What's Needed to Accelerate Virtual Power Plant Adoption to Meet Growing Energy Demand?
    Dec 1 2025

    A virtual power plant (VPP) is a collection of small-scale energy resources that, aggregated and coordinated with grid operations, can provide the same reliability and economic value to the grid as a traditional power plant, according to the nonprofit organization RMI.

    And VPPs can help utility customers earn money. Large energy users can earn up to $100,000 a year through CPower Energy's program, said Mike Smith, CEO of CPower.

    A recent report from RMI identified some of the gains VPPs have made recently. For example, 10 legislatures introduced VPP bills and four states passed VPP legislation in 2024. But more action is needed to meet the organization's goal of ensuring all US electricity consumers have access to VPP programs by 2035. Action is also needed to accelerate VPP adoption to meet booming energy demand.

    Gabriela Olmedo, head of policy and regulatory affairs at EnergyHub.

    Mike Smith, CEO at CPower.

  • Small Farmer Has Bragging Rights For Charging EV with Solar, He Says
    Nov 11 2025

    Tim Nesbitt, former chief of staff to Oregon Governor Ted Kulongoski, claims bragging rights for charging his Chevy Bolt EV solely with solar power on his small farm, which is carbon neutral--and sometimes carbon negative. He has 84 ground-mounted solar panels that generate 18-19 kWh daily. Batteries provide some resilience for critical systems such as the internet and refrigeration.

    Nesbitt's friend, another farmer, is earning $1,500 per acre for selling solar installed on his farm by a third party--more than he can make by growing certain crops.

    Through the EVmath program, Nesbitt tells his story to help other rural residents understand the benefits of driving EVs.

  • How "Junk" Data Boosts Data Center Energy Costs
    Oct 24 2025

    Whether you're a consumer who hoards old photos or a company that hangs onto unusable data, you're boosting data centers' energy costs.

    By focusing on reducing hoarded--or "junk" data--and improving efficiency, data centers can slash power consumption by 40% to 60%, according to Simon Ninan, senior vice president, business strategy, Hitachi Vantara.

    Ninan provides details about how data centers can achieve this kind of savings.
