A shift to renewable energy is ‘hopeless’ without efficiencies, environmentalist says

Explorer and environmentalist Bertrand Piccard has called for a renewed focus on cutting energy waste, saying it’s “hopeless” to shift to renewables without improving efficiency.
Around three-quarters of the world’s energy is wasted, Piccard told an “IOT: Powering the Digital Economy” panel moderated by CNBC’s Silvia Amaro. This estimate is based on waste “due to inappropriate behaviour and inefficient systems or infrastructures,” he told CNBC separately via email.
Piccard, who is founder and chairman of the environmental non-profit organization Solar Impulse Foundation, said that “we live in a world of waste.”
“So if we try to replace fossil [fuel] energy with renewables without being efficient, without reducing the consumption, it’s hopeless,” he said.
Another issue Piccard highlighted was that some countries only consider wind and solar as alternative renewable energy sources.
Biogas, produced by the breakdown of organic matter such as food, has been “excluded … from the taxonomy” in Europe, he said, and people also forget about geothermal energy, which uses heat from the earth.
A report published in October by the European Commission showed that while bioenergy continued to be the main source of renewable energy in the EU in 2021 — at around 60% — biogas made up just 10% of this share. Geothermal energy accounted for just 2.7% of renewable energy consumption, while wind power was 13.2% and solar energy was 7.2%.
“So we focus on producing more, instead of consuming less, and in the production that we want to do, we forget a lot of different types of renewable energies that we don’t take into consideration,” he said.
As a result of these issues, Piccard said there’s a risk that green energy targets could be missed — as well as the opportunity to produce cheaper energy locally.
“So every country wants … energy independence, more competitiveness, and they forget that the only way to reach it is by energy efficiency, and renewables,” he said.
‘Paradox’ of China’s solar panel oversupply
Piccard also discussed the ongoing concerns about the potential oversupply of solar panels from China to the European market.
“It’s a bit of a paradox because the Chinese have killed the European solar industry, but they have saved the world by showing that solar energy can be so [much] cheaper than anything else,” he said.
There have been growing concerns in Europe and the U.S. that a surplus of subsidized clean energy products, including solar panels, from China is making it more difficult for their domestic industries to compete.
Earlier this month, the European Commission launched two investigations into Chinese solar panel manufacturers that it said could have benefitted from “potentially market distortive” subsidies.
Meanwhile, U.S. Treasury Secretary Janet Yellen said last week that she wouldn’t rule out possible tariffs on China’s green energy exports.
Piccard said it was also important to consider the potential advantages of Chinese solar panels in Europe, however. For example, he said that these panels could be used to generate cheaper electricity in the region, which could then be used to produce hydrogen locally.
“I think, instead of fighting against the obstacle, I think you need to use the situation to see how there will be outcomes on the side of the problem that can that can be beneficial for us,” he said.
Piccard added that when he initiated the Solar Impulse project over 20 years ago, solar energy was 40 times more expensive than it is today. Solar Impulse 2 became the first solar-powered electric airplane to circumnavigate the globe in 2016.
“So I’m sorry, maybe it’s not politically correct but I’m thanking China for the decrease [in] price of solar energy that has given a wonderful push to renewable energies — we would not be at this point without China,” he said.
China just laid out a plan to roll out over 100,000 ultra-fast EV charging stations by 2027 – and they’ll all be open to the public.
The National Development and Reform Commission’s (NDRC) joint notice, issued on Monday, asks local authorities to put together construction plans for highway service areas and prioritize the ones that see 40% or more usage during holiday travel rushes.
The NDRC notes that China’s ultra-fast EV charging infrastructure needs upgrading as more 800V EVs hit the road. Those high-voltage platforms can handle super-fast charging in as little as 10 to 30 minutes, but only if the charging hardware is up to speed.
China had 31.4 million EVs on the road at the end of 2024 – nearly 9% of the country’s total vehicle fleet. But charging access is still catching up. As of May 2025, there were 14.4 million charging points, or roughly 1 for every 2.2 EVs.
To keep the grid running smoothly, China wants new chargers to be smart, with dynamic pricing to incentivize off-peak charging and solar and storage to power the charging stations.
To make the business side work, the government is pushing for 10-year leases for charging station operators, and it’s backing the buildout with local government bonds.
The NDRC emphasized that the DC fast chargers built will be open to the public. This is a big deal because a lot of fast chargers in China aren’t. For example, BYD’s new megawatt chargers aren’t open to third-party vehicles.
As of September 2024, China had expanded its charging infrastructure to 11.4 million EV chargers, but only 3.3 million were public.

Find out more on today’s legally challenging episode of Quick Charge!
An arbitration “court” found that Tesla misled customers with its Full Self Driving product, and has now been forced to refund at least one person’s $10,000 payment (plus legal fees) for the not-quite autonomous driving software. France, too, is piling on claims of deceptive business practices – but there’s some good news for FSD fans! If you’re still willing to pay for it, Tesla will thrown in 0% financing on a brand new Cybertruck.
