Most Americans see climate change as a major threat. But income level seems to guide one’s willingness or ability to live a greener lifestyle.

Fifty-nine percent of high-income consumers always or often choose sustainable products, whereas that’s true for only 44% and 42% of mid- and low-income households, respectively, according to a new Deloitte survey. The poll was global, but the findings were consistent across individual countries such as the U.S., said James Cascone, partner at Deloitte.

A sustainable purchase would largely aim to reduce your planet-warming greenhouse gas emissions — for example, replacing a household appliance with a more energy-efficient counterpart or buying an electric vehicle.

Low earners were much more likely to cite cost as a barrier to an environmentally friendly purchase than high earners, Deloitte found.

“Cost is a big factor,” said Gregory Keoleian, director of the Center for Sustainable Systems at the University of Michigan.

High earners generally have the largest carbon footprints, noted Deloitte’s Cascone. They own bigger homes, have more vehicles and travel more by air, for example, but they can also more easily afford to change their behavior.

Sustainable products tend to carry a “green premium,” meaning they’re generally more expensive than the standard, experts said.

We're not reducing emissions fast enough, says professor

Even if a purchase would ultimately save money over the long term — due to lower household energy costs, for example — people living paycheck to paycheck generally can’t afford to invest in things such as new home insulation or efficient windows, said Katharine Hayhoe, chief scientist for the Nature Conservancy and professor at Texas Tech University.

A new national rebate program aims to ease or eliminate the cost burden of such investments, especially for lower-earning households. EV tax credits also seek to reduce net cost to buyers.

Here are some easy — and inexpensive or no-cost — ways to reduce your carbon footprint today, according to efficiency and environmental experts. You may even save money in the process.

1. Switch to LED lightbulbs ASAP

Switching out older lightbulbs in your home for LED bulbs as soon as possible is among the best actions you can take, according to Hayhoe.

“It’s a no-brainer,” she said.

Why? LED, which stands for light-emitting diode, is today’s most-efficient lighting technology, according to the U.S. Department of Energy.

LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs, for example, the Energy Department said. They also last about three to five times longer than compact fluorescent light bulbs.

As such, the average household saves about $225 in energy costs per year by switching to LED lighting, the Energy Department said. While LEDs are a bit more expensive, costs have decreased “dramatically” and prices are expected to fall further, officials say.

However, households start saving money very quickly after switching to LED lighting, meaning it makes sense from both a financial and environmental standpoint to switch now rather than later, Keoleian said.

2. Cut food waste

The average American wastes more than 400 pounds of food a year. In total, about 30% to 40% of edible food is wasted, Keoleian said.

Reducing such waste saves emissions across the food supply chain on agricultural production inputs such as fuel for tractors and fertilizers, and in other areas such as refrigeration and food distribution, he said.

Organic waste in landfills also generates methane, a greenhouse gas that is more than 25 times more potent than carbon dioxide at trapping heat in the atmosphere.

The U.S. Environmental Protection Agency publishes a list of ways to prevent food waste at home, such as planning meals for the week before shopping and properly storing fruits and vegetables.

Composting food scraps also “significantly” reduces methane emissions from waste. Check out this EPA list for tips on how to start composting at home.

3. Stop ‘energy vampires’

Many household appliances draw power from electrical outlets even when off or idle.

These “energy vampires” — which may include computers, hair dryers, cable boxes and coffee makers, among others — can add $100 to $200 a year to the average household energy bill, according to the Energy Department.

Unplug these devices when not in use. You can also plug them into a power strip or an outlet with a wall switch and switch the whole system on or off when you need to.

4. Seal any leaks

Heating and cooling accounts for nearly half the average home’s energy use, according to the Consumer Federation of America. In aggregate, small leaks around the house amount to leaving open a 3-foot-by-3-foot window, the group said.

“Simple steps” such as caulking windows and sliding draft guards under doors can save up to 20% on heating costs, the group said.

Even buying a clear, plastic film for windows helps insulate from heat and cold by adding a pocket of air between you and the outside, Hayhoe said. Indeed, she did this in her home.

5. Save water

Conserving water is important because water and wastewater treatment are carbon-intensive processes, as is heating that water at home, Keoleian said.

There are many ways to cut water use. For example, fully load machines such as dishwashers and clothing washers. Those who wash dishes by hand can be efficient by using two basins (one for cleaning and another for rinsing) instead of running the water.

Also, use cold water when possible. A washing machine spends 90% of its energy to heat water, for example, the Consumer Federation of America said. For drying, use a clothesline in warmer weather. On a related note, open the door at the end of a dishwasher’s wash cycle and let the dishes air dry.

Even putting something like a brick in your toilet tank will displace — and therefore save — water.

6. Tweak your diet, even slightly

Certain foods are more carbon-intensive than others.

Eating a more plant-based diet and cutting red meat intake is generally more environmentally friendly, as well as cheaper and healthier, experts said.

For example, beef’s greenhouse gas emissions per kilogram is about seven times higher than that of farm-raised fish, 10 times that of chicken and 230 times that of nuts or root vegetables. This is largely because cows produce a lot of methane.

While red meat — beef, pork and lamb — accounts for about 10% of the calories in an average diet, it contributes almost half the greenhouse gas emissions from agricultural production, Keoleian said.

Legumes, beans, nuts and lentils are very good protein substitutes, he said.

“You could still eat meat,” Keoleian said. “Just limit it and have a diversity of diet, which will be healthier.”

Of course, this might not be possible, he said. Food and diet are cultural, and not everyone likes plant-based proteins.

7. Use cars efficiently

Car owners — even those with gas guzzlers — can use their vehicles more efficiently.

For example, “trip chaining” means bundling trips. An example of this would be picking up groceries on the way home from work instead of making a one-off trip to the store.

Households with more than one car can also “rightsize,” a concept that matches the most efficient car with the trip. For example, that may mean commuting to work in a sedan instead of an SUV or pickup truck, Keoleian said.

Public transit, walking, biking and carpooling are other options, too, Hayhoe said.

8. Talk about it

Reducing individual carbon footprints can have an enormous influence on how businesses cut their greenhouse gas emissions, experts said. An industry will respond to consumer choices, sentiment and buying behavior, they said.

Consumers can therefore have a big effect by talking with friends, family and colleagues about how they saved money by living greener, Hayhoe said.

“The No. 1 thing that costs nothing and is most impactful is starting conversations about why this matters,” Hayhoe said.

“Do something — anything — and then talk about it,” she added. “Make it contagious in a good way.”

Tesla prototype sparks speculation: a Model Y, maybe slightly smaller

Tesla prototype sparks speculation: a Model Y, maybe slightly smaller

A new Tesla prototype was spotted again, reigniting speculation among Tesla shareholders, even though it’s likely just a Model Y, potentially a bit smaller, and the upcoming stripped-down, cheaper version.

Over the last few months, there have been several sightings of what appears to be a Model Y with camouflage around Tesla’s Fremont factory.

It sparked a lot of speculation about it being the new “affordable” compact Tesla vehicle.

There’s confusion in the Tesla community around Tesla’s upcoming “affordable” vehicles because CEO Elon Musk falsely denied a report last year about Tesla’s “$25,000” EV model being canceled.

Advertisement – scroll for more content

The facts are that Musk canceled two cheaper vehicles that Tesla was working on, commonly referred as “the $25,000 Tesla” in early 2024. Those vehicles were codenamed NV91 and NV92, and they were based on the new vehicle platform that Tesla is now reserving for the Cybercab.

Instead, Musk noticed that Tesla’s Model 3 and Model Y production lines were starting to be underutilized as the Company faced demand issues. Therefore, Tesla canceled the vehicles program based on the new platform and decided to build new vehicles on Model 3/Y platform using the same production lines.

We previously reported that these electric vehicles will likely look very similar to Model 3 and Model Y.

In recent months, several other media reports reinforced this, and Tesla all but confirmed it during its latest earnings call, when it stated that it is “limited in how different vehicles can be when built on the same production lines.”

Now, the same Tesla prototype has been spotted over the last few days, and it sent the Tesla shareholders community into a frenzy of speculations:

Electrek’s Take

As we have repeatedly reported over the last year, the new “affordable” Tesla “models” coming are basically only stripped-down Model 3 and Model Y vehicles.

They might end up being a little smaller by a few inches, and Tesla may use different model names, but they will be extremely similar.

If this is it, which is possible, you can see it looks almost exactly like a Model Y.

It’s hard to confirm if it’s indeed smaller because of the angle of the vehicle compared to the other Model Ys, but it’s not impossible that the wheelbase is a bit smaller – although it’s hard to confirm.

Either way, the most significant changes for these stripped-down, more affordable “models” are expected to be cheaper interior materials, like textile seats instead of vegan leather, no heated or ventilated seats standard, no rear screen, maybe even no double-panned acoustic glass and a lesser audio system.

As previously stated, the real goal of these new variants, or models, is to lower the average sale price in order to combat decreasing demand and maintain or increase the utilization rate of Tesla’s current production lines, which have been throttled down in the last few years to now about 60% utilization.

If this trend continues, Tesla would find itself in trouble and may even have to close its factories.

Ethereum is powering Wall Street’s future. The crypto scene at Cannes shows how far it’s come

Ethereum is powering Wall Street's future. The crypto scene at Cannes shows how far it's come

Ethereum succeeded beyond anyone's expectations, says network co-founder Vitalik Buterin at EthCC

CANNES — Wall Street’s new plumbing is being built on Ethereum and this week its architects took over the same French Riviera villas and red carpet venues that host the Cannes Film Festival in May.

The Ethereum Community Conference, or EthCC, took over the beachside town that was swarming with crypto founders, developers, and some of the institutional giants now building atop the infrastructure.

The crypto elite climbed the iconic red-carpeted steps of the Palais des Festivals — a cinematic landmark now repurposed as the stage for Ethereum’s flagship European event.

“The atmosphere this year was palpable in Cannes,” said Bettina Boon Falleur, the powerhouse behind EthCC for the past seven years. “The prestige of the location, combined with the quality of talks, has reinforced Ethereum’s stature and purpose in the wider ecosystem.”

Private parties sprawled across cliffside estates and exclusive resorts, but the conversations were less about price action and more about the blockchain’s evolving role as the back-end of global finance.

EthCC, now in its eighth year, has tracked Ethereum’s trajectory from scrappy experiment to institutional backbone.

“That impact was unmistakable this year,” Falleur said. “From Robinhood embracing decentralized finance infrastructure via Arbitrum to local governments like the City of Cannes exploring deeper integration with the crypto economy.”

Indeed, one of the boldest moves came this week from Robinhood, which became the first publicly traded U.S. company to launch tokenized stocks on-chain.

At a product showcase held inside a Belle Époque mansion overlooking the sea, Robinhood unveiled a sweeping new crypto strategy — including the ability for European users to trade tokenized U.S. stocks and ETFs via Arbitrum, a Layer 2 network built on Ethereum.

The announcement helped push Robinhood stock past $100 for the first time, capping off a week of fresh all-time highs and a more than 30% rally since being snubbed by the S&P 500 during a recent rebalance.

Inside the Palais des Festivals, ETHCC draws founders, developers, and institutions into the same halls that host the world’s biggest film premieres — this time, for the future of finance.

Ether, the token native to the Ethereum blockchain, was up nearly 6% on the week and several public equities tied to the blockchain have rallied alongside it.

BitMine Immersion Technologies, a company that mines bitcoin, gained more than 1,200% since announcing it would make ether its primary treasury reserve asset. Bit Digital, which recently exited bitcoin mining to “become a pure play” ethereum staking and treasury company, gained more than 34% this week. And SharpLink Gaming, which added more than $20 million in ether to its balance sheet this week, jumped more than 28% on Thursday.

Ether ETF inflows are rising again too — a sign that institutional investors are warming back up.

Ether is still down more than 20% this year and lags far behind bitcoin in market cap and adoption. But funds tracking ETH have seen two straight months of mostly net inflows, according to CoinGlass data. Still, ether ETFs total just $11 billion — compared to $138 billion in bitcoin ETFs.

Institutions aren’t betting on Ethereum for hype — they’re betting on infrastructure.

Even as prices stall and the network faces headwinds from slower base layer revenues and faster rivals like Solana, the momentum is shifting toward utility.

“Ethereum is getting plugged into these core transactional systems,” Paul Brody, global blockchain leader at EY, told CNBC on the sidelines of EthCC. “Investors, savers, people moving money — they are going to start shifting from some of the older mechanisms of doing this into Ethereum ecosystems that can do these transactions faster, cheaper, but also very importantly, with significant new functionality attached to it.”

Crypto founders and developers climb the iconic red-carpeted steps of the Palais des Festivals — a familiar backdrop for the Cannes Film Festival, now repurposed for Ethereum’s flagship European event.

Deutsche Bank recently announced it’s building a tokenization platform on zkSync — a faster, cheaper blockchain built on top of Ethereum — to help asset managers issue and manage tokenized funds, stablecoins, and other real-world assets while meeting regulatory and data protection requirements.

Coinbase and Kraken are also racing to own the crossover between traditional stocks and crypto.

Coinbase has filed with the SEC to offer trading in tokenized public equities, a move that would diversify its revenue stream and bring it into more direct competition with brokerages like Robinhood and eToro.

Kraken announced plans to offer 24/7 trading of U.S. stock tokens in select overseas markets.

BlackRock‘s tokenized money market fund, BUIDL — launched on Ethereum last year — offers qualified investors on-chain access to yield with redemptions settled in USDC in real time.

Stablecoins, meanwhile, continue to serve as the backbone of Ethereum’s financial layer.

Circle’s USDC — the second-largest stablecoin — still settles around 65% of its volume on Ethereum’s rails. According to CoinGecko’s latest “State of Stablecoins” report, Ethereum accounts for nearly 50% of stablecoin market share.

“The builders and contributors at EthCC aren’t chasing the next bull run,” Falleur said, “they’re laying the groundwork to make Ethereum home for the next billion users.”

Even as newer blockchains tout faster speeds and lower fees, Ethereum is proving its staying power as a trusted network.

Vitalik Buterin, Ethereum’s co-founder, told CNBC in Cannes that there is an assumption that institutions only care about scale and speed — but in practice, it’s the opposite.

Ethereum co-founder Vitalik Buterin delivers a keynote at ETHCC, laying out the network’s next steps — and its values test — as institutional adoption accelerates.

EthCC

“A lot of institutions basically tell us to our faces that they value Ethereum because it’s stable and dependable, because it doesn’t go down,” he said.

Buterin added that firms often ask about privacy and other long-term features — the kinds of concerns that institutions, he said, “really value.”

Tomasz Stańczak, the new co-executive director of the Ethereum Foundation, said institutions are choosing Ethereum for the same core reasons.

“Ten years without stopping for a moment. Ten years of upgrades, with a huge dedication to security and censorship resistance,” he said.

He added that when institutions send orders to the market, they want to be “absolutely sure that their order is treated fairly, that nobody has preference, that the transaction actually is executed at the time when it’s delivered.”

Those guarantees have become increasingly valuable as stablecoins and tokenized assets move into the mainstream.

The Senate’s recent passage of the GENIUS Act, along with Circle’s IPO, gave the industry a regulatory tailwind and helped reinforce Ethereum’s role as the infrastructure layer for tokenized finance.

Ethereum’s core values — neutrality, security, and censorship resistance — are emerging as competitive advantages.

The real test now is whether Ethereum can scale without losing its values.

“We don’t just want to succeed,” Buterin said from the mainstage of the Palais this week. “We want to be something that is worthy of succeeding.”

He said the hope is that future generations will look back and see a network that truly delivered openness, freedom, and permissionless access to the masses.

White-clad guests dance poolside at the rAAVE party in Cannes.

But the week didn’t end in the conference halls, it closed with tradition. On the balcony of Villa Montana, overlooking the Bay of Cannes, the rAAVE party lit up.

White-clad guests sipped cocktails as the DJ spun by the pool, haze curling from smoke machines.

This year, Chainlink co-founder Sergey Nazarov and DeFi icon Stani Kulechov, founder of Aave, stood atop the balcony overlooking the crowd and the light-dotted skyline of Cannes.

It was a fitting snapshot of the momentum behind Ethereum’s institutional rise and symbolic of Web3’s shift from niche experiment to financial mainstay.
