Sunrise brief: Solar can help with marijuana’s green problem

Also on the rise: Maryland community solar install to take just nine weeks. Debunking solar myth about land use. And more.

Car batteries can optimize the power grid

Australian researchers have found that if 10% of vehicles are electric and utilize V2G connections, they could reduce peak electricity demand at local substations by 6% and save car owners hundreds of dollars per year on charging costs.

A look at the great transformer shortage affecting U.S. utilities

An NREL team finds that lead times for transformers has grown fourfold in three years, with orders sometimes taking two years. Additionally price increases of four to nine times have been reported in the past 3 years.

Solar now accounts for over 50% of new electricity capacity added to the U.S. grid

Looking back at the first full year since passage of the Inflation Reduction Act, the U.S. Solar Market Insight, Year-in-Review 2023 shows that the legislation has skyrocketed the industry and will have a lasting economic impact in terms of energy, jobs and investment opportunity.

Solar generated 5.5% of U.S. electricity in 2023, a 17.5% increase

Solar generation grew by 17.5% compared to 2022, albeit at a lower rate, adding just over 33 TWh of generation compared to the 40 TWh added in 2022.

Calculating potential impact of EPA’s $7 billion Solar for All program

Solar for All can jumpstart the solar market and expand the benefits of solar far beyond the initial five years of the program. Clean Energy States Alliance notes that after the award decisions are announced, additional states will be evaluating strategies and more households will benefit from this funding over time.

MIT research provides roadmap to perovskite passivation

In previous work, research teams developed methods for passivation, but there wasn’t clear understanding of how the process works. The new MIT study provides details on how to passivate the material’s surface so that the perovskite no longer degrades so rapidly or loses efficiency.

U.S. solar up 52% in 2023 as nation deploys 35.3 GW of capacity

Bloomberg NEF says U.S. clean energy generation grew by 0.9%, with wind and hydro generation falling and solar generation growing 15.4%.

NREL finds 100% renewable scenario improves LA air quality and health

NREL modeled that LA and surround counties could save over $4 billion from improved health outcomes. The most significant reductions in emissions resulted from electrification and infrastructural changes to the non-power sector, such as transportation and buildings.

Beaming radio frequency solar power from space

Researchers at the California Institute of Technology successfully beamed solar power from space to Earth in July. The experimental microwave-beaming satellite was tested for eight months, uncovering existing strengths and weaknesses that will guide future developments of space solar power.
