More Than 40% of World’s Electricity Came From Zero-Carbon Sources in 2023

Zero-carbon technologies comprised more than 40% of global electricity generation for the first time in 2023, according to a report released Tuesday from BloombergNEF.

Renewable energy sources like wind and solar made up 17% of total electricity generation, and hydroelectric and nuclear power contributed 24%. Fossil fuels including coal and natural gas produced 57% of global electricity last year.

“We’ve consistently seen the penetration of renewables rising every year, and this year we hit quite a few milestones that had felt harder to reach in past years,” said Meredith Annex, head of clean power at BNEF.

One such milestone: Solar and wind represented more than 90% of global energy capacity additions last year, a step up from 2022. Global wind capacity also crossed the one-terawatt threshold. And Brazil, the country with the cleanest power mix of the G-20 economies, hit 88% renewable power generation in 2023.

“It just shows the momentum that the space is having. A lot of that does tie into the investment story, where you’ve got rising—skyrocketing, honestly—investment into solar,” Annex said.

Mainland China accounted for almost a third of total renewable energy output last year. The country recently reached its 2030 target for wind and solar energy six years early, according to a statement from its National Energy Administration, and it has pulled back on permits for new coal-fired power plants. The country’s rapid deployment of renewables has some analysts wondering if it will reach peak fossil fuel consumption this year. Declining emissions in China would signal a turning point because it is the world’s largest polluter, comprising nearly a third of global greenhouse gas emissions, according to the International Energy Agency.

Despite rapid growth in renewables, countries’ current commitments aren’t sufficient to limit global warming to 1.5 degrees Celsius, the goal outlined in the 2015 Paris Agreement, according to the IEA. Advanced economies would need to slash emissions by 80% by 2035 to meet the goal.

At last December’s COP28, a global climate conference hosted by the United Nations, participating countries agreed to triple renewable energy capacity by 2030. BNEF has forecast that achieving this goal would require investments in renewables to increase to 1.6 times 2023 levels from 2024 to 2030.

So far, that increase hasn’t materialised. Global investments in renewables are roughly on par with 2023 levels, at $313 billion in the first half of 2024, according to the new BNEF analysis. “We’re expecting steady growth, but steady growth does not get you to net zero,” Annex said.

The topline numbers obscure bigger changes under the surface. Average spending in the U.S. is up by about 63% compared with levels before the 2022 Inflation Reduction Act, which offers generous subsidies and tax breaks to promote decarbonisation. And while Chinese investment is actually down 4% from the same period in 2023, Annex said the dip is due to cheaper equipment for wind and solar, not a decline in demand.

The second half of this year will be a “defining moment,” for the investment landscape, Annex said. Steady growth “is definitely a positive, and it could be a sign that the industry as a whole is reaching a new kind of status quo, but we need to help expand even faster if we’re going to be in line with net zero.”

Berkshire began liquidating its big stake in the banking company in mid-July—and has already unloaded about 15% of its interest. The selling has been fairly aggressive and has totaled about $6 billion. (Berkshire still holds 883 million shares, an 11.3% interest worth $35 billion based on its most recent filing on Aug. 30.)

The selling has prompted speculation about when CEO Warren Buffett, who oversees Berkshire’s $300 billion equity portfolio, will stop. The sales have depressed Bank of America stock, which has underperformed peers since Berkshire began its sell program. The stock closed down 0.9% Thursday at $40.14.

It’s possible that Berkshire will stop selling when the stake drops to 700 million shares. Taxes and history would be the reasons why.

Berkshire accumulated its Bank of America stake in two stages—and at vastly different prices. Berkshire’s initial stake came in 2017 , when it swapped $5 billion of Bank of America preferred stock for 700 million shares of common stock via warrants it received as part of the original preferred investment in 2011.

Berkshire got a sweet deal in that 2011 transaction. At the time, Bank of America was looking for a Buffett imprimatur—and the bank’s stock price was weak and under $10 a share.

Berkshire paid about $7 a share for that initial stake of 700 million common shares. The rest of the Berkshire stake, more than 300 million shares, was mostly purchased in 2018 at around $30 a share.

With Bank of America stock currently trading around $40, Berkshire faces a high tax burden from selling shares from the original stake of 700 million shares, given the low cost basis, and a much lighter tax hit from unloading the rest. Berkshire is subject to corporate taxes—an estimated 25% including local taxes—on gains on any sales of stock. The tax bite is stark.

Berkshire might own $2 to $3 a share in taxes on sales of high-cost stock and $8 a share on low-cost stock purchased for $7 a share.

New York tax expert Robert Willens says corporations, like individuals, can specify the particular lots when they sell stock with multiple cost levels.

“If stock is held in the custody of a broker, an adequate identification is made if the taxpayer specifies to the broker having custody of the stock the particular stock to be sold and, within a reasonable time thereafter, confirmation of such specification is set forth in a written document from the broker,” Willens told Barron’s in an email.

He assumes that Berkshire will identify the high-cost Bank of America stock for the recent sales to minimize its tax liability.

If sellers don’t specify, they generally are subject to “first in, first out,” or FIFO, accounting, meaning that the stock bought first would be subject to any tax on gains.

Buffett tends to be tax-averse—and that may prompt him to keep the original stake of 700 million shares. He could also mull any loyalty he may feel toward Bank of America CEO Brian Moynihan , whom Buffett has praised in the past.

Another reason for Berkshire to hold Bank of America is that it’s the company’s only big equity holding among traditional banks after selling shares of U.S. Bancorp , Bank of New York Mellon , JPMorgan Chase , and Wells Fargo in recent years.

Buffett, however, often eliminates stock holdings after he begins selling them down, as he did with the other bank stocks. Berkshire does retain a smaller stake of about $3 billion in Citigroup.

There could be a new filing on sales of Bank of America stock by Berkshire on Thursday evening. It has been three business days since the last one.

Berkshire must file within two business days of any sales of Bank of America stock since it owns more than 10%. The conglomerate will need to get its stake under about 777 million shares, about 100 million below the current level, before it can avoid the two-day filing rule.

It should be said that taxes haven’t deterred Buffett from selling over half of Berkshire’s stake in Apple this year—an estimated $85 billion or more of stock. Barron’s has estimated that Berkshire may owe $15 billion on the bulk of the sales that occurred in the second quarter.

Berkshire now holds 400 million shares of Apple and Barron’s has argued that Buffett may be finished reducing the Apple stake at that round number, which is the same number of shares that Berkshire has held in Coca-Cola for more than two decades.

Buffett may like round numbers—and 700 million could be just the right figure for Bank of America.
