How Solar Is Helping Keep the Lights On This Summer

On the fastest-growing power source, Hawaii’s climate settlement, and friendly monkeys

Current conditions: China issued a rainstorm warning for its already-sodden southern provinces • Two people were killed in severe storms in Moscow • America’s brutal heat wave will shift into the Mid-Atlantic this weekend.

THE TOP FIVE

1. Solar to provide one-fifth of global electricity during peak summer hours

During the sunniest hours of the longest days of the year, solar power can now provide about 20% of the world’s electricity, according to new estimates from energy think tank Ember. That’s up from 16% last year. Throughout the entire month of June, solar will account for roughly 8.2% of global electricity, up from 6.7% in the same month last year, and higher than the 5.5% annual average across the whole of 2023. The report underscores the rapid expansion of solar, which is now the fastest-growing source of electricity. “As solar continues to expand, it is poised to further transform the power sector and accelerate the world’s transition to renewable energy,” the authors said.

2. Hawaii agrees to ‘groundbreaking’ settlement with youth climate activists

The state of Hawaii has committed to decarbonizing its transportation system by 2045 as part of a settlement in a lawsuit brought by a group of young climate activists. The “groundbreaking” agreement, which can be enforced in court, also calls for a youth council to be created to advise the transportation department. The 13 plaintiffs – most of whom are Indigenous – filed their lawsuit in 2022, accusing Hawaii’s department of transportation of harming their health and infringing on their right to a clean environment, thus violating the state constitution. “You have a constitutional right to fight for life-sustaining climate policy and you have mobilized our people in this case,” said the state’s governor, Josh Green. Denise Antolini, an emeritus professor of law at the University of Hawaii Law School, told The Guardian the settlement is important because of its focus on transportation specifically, which is a huge source of emissions but “tends to get ignored.”

  • 3. Report connects climate change to recent Mexico heat wave

    A report from World Weather Attribution concluded that the oppressive heat wave that baked Central America, Mexico, and some Southwestern states in recent weeks was made 35 times more likely due to climate change caused by burning fossil fuels. The analysis was packed with other statistics that tell an unsettling story:

    • 125 – degrees Fahrenheit reached in the Sonoran Desert last week, the hottest day in Mexican history.
    • 2.5 – degrees Fahrenheit by which climate change made the heat dome hotter.
    • 3 – degrees Fahrenheit by which climate change increased nighttime temperatures during the heat wave.
    • Every 15 years – the frequency with which this kind of extreme heat is now expected to occur.
    • Every 60 years – the frequency with which this kind of extreme heat was expected to occur in the year 2000, when global temperatures were lower.
    • 125 – number of people who are known to have died in the heat wave.

    4. Startup plans to use methane to make graphite

    A California-based startup called Molten Industries is trying to transform natural gas into a key component for making lithium-ion batteries. The company has “developed a specialized technique to break methane into graphite and hydrogen, the latter of which can be used as a source of clean energy,” Bloombergreported. Graphite is used to make batteries, but most of it comes from China, so Molten wants to onshore production at a competitive cost. The company says its graphite production was a sort of happy accident. “Our original focus was just to make the lowest-cost hydrogen with the most energy-efficient reactor possible,” said co-founder and CEO Kevin Bush. Molten announced this week a $25 million series A round of funding led by Breakthrough Energy Ventures. It plans to use the money to build its first modular commercial reactor.

    5. Amazon to replace plastic ‘air pillows’ in packages with recycled paper filler

    Amazon announced this week it will stop using plastic “air pillows” to protect the packages it ships in North America and instead switch to recycled paper. The shift will be completed by the end of 2024, and will mean 15 billion plastic air pillows are removed from use each year. The move is driven in part by support among investors for cutting waste, but it’s helped by the fact that Amazon discovered recycled paper protects packages better than the plastic pillows anyway.

    THE KICKER

    A new study found that monkeys living on an island off Puerto Rico responded to the destruction from 2017’s Hurricane Maria by becoming less aggressive and more cooperative with one another in order to share scarce resources, and that this shift in social behavior helped boost their survival.

    Here Are the Grants EPA Canceled

    The agency provided a list to the Sierra Club, which in turn provided the list to Heatmap.

    Officials at the Environmental Protection Agency remain closed-lipped about which grants they’ve canceled. Earlier this week, however, the office provided a written list to the Sierra Club in response to a Freedom of Information Act request, which begins to shed light on some of the agency’s actions.

    The document shows 49 individual grants that were either “canceled” or prevented from being awarded from January 20 through March 7, which is the day the public information office conducted its search in response to the FOIA request. The grants’ total cumulative value is more than $230 million, although some $30 million appears to have already been paid out to recipients.

    The New Campaign to Save Renewables: Lower Electricity Bills

    Defenders of the Inflation Reduction Act have hit on what they hope will be a persuasive argument for why it should stay.

    With the fate of the Inflation Reduction Act and its tax credits for building and producing clean energy hanging in the balance, the law’s supporters have increasingly turned to dollars-and-cents arguments in favor of its preservation. Since the election, industry and research groups have put out a handful of reports making the broad argument that in addition to higher greenhouse gas emissions, taking away these tax credits would mean higher electricity bills.

    The American Clean Power Association put out a report in December, authored by the consulting firm ICF, arguing that “energy tax credits will drive $1.9 trillion in growth, creating 13.7 million jobs and delivering 4x return on investment.”

    Current conditions: Severe thunderstorms are expected across the Mississippi Valley this weekend • Storm Martinho pushed Portugal’s wind power generation to “historic maximums” • It’s 62 degrees Fahrenheit, cloudy, and very quiet at Heathrow Airport outside London, where a large fire at an electricity substation forced the international travel hub to close.

    1. Trump issues executive order to expand critical mineral output

    President Trump invoked emergency powers Thursday to expand production of critical minerals and reduce the nation’s reliance on other countries. The executive order relies on the Defense Production Act, which “grants the president powers to ensure the nation’s defense by expanding and expediting the supply of materials and services from the domestic industrial base.”
