Scientists have made a fundamental breakthrough in their attempts to replicate photosynthesis – the ability of plants to harvest the power of sunlight – in the hope of making unlimited amounts of green energy from water and sunlight alone.

The researchers have assembled genetically modified viruses into wirelike structures that are able to use the energy of the sun to split water molecules into their constitute parts of oxygen and hydrogen, which can then be used as a source of chemical energy.

If the process can be scaled up and made more efficient, it promises to produce unlimited quantities of hydrogen fuel, a clean source of energy that can be used to generate electricity as well as acting as a portable, carbonfree fuel for cars and other vehicles.

Replicating photosynthesis – in which plants convert sunlight into a store of chemical energy – has been a dream of the alternative energy business for decades. The drive was given an extra boost with warnings by the U.S. military that there could be serious global oil shortages by 2015.

Splitting water molecules into oxygen and hydrogen is seen as a critical first step in this process of artificial photosynthesis. Although it is possible to split the molecules using solar electricity, the process is not very efficient. In the latest study, scientists were able to split water directly with sunlight, without using solar panels.

Plants convert sunlight into chemical energy using the green chlorophyll pigment found in leaves, which traps packets of light and uses the energy to transport electrons from one molecular complex to another within the plants cells. The end result is the conversion of carbon dioxide and water into glucose, which can be stored as starch or as other forms of plant carbohydrates.

Some researchers have tried to emulate this natural photosynthetic process by using the appropriate parts of plants but these structures tend to be unstable. Instead, Angela Belcher at the Massachusetts Institute of Technology borrowed the method rather than using the components of plants.

The scientists genetically engineered a harmless virus called M13, which normally infects bacteria, so that it would bind to a catalyst called iridium oxide and a biological pigment, zinc porphyrins. The viruses naturally arranged themselves into wirelike structures and the catalyst and pigments effectively harvested sunlight to split the oxygen from the water molecules.

Professor Belcher said that the role of the pigment was to act like an antenna to capture the light and then transfer the energy down the length of the virus. She said: The virus is a very efficient harvester of light, with these porphyrins attached. We use the components people have used before but we use biology to organize them for us, so you get better efficiency.

So far, the team has only been able to split off oxygen, which is the most challenging part of the watersplitting process. The hydrogen splits into its component parts, protons and electrons, and the next stage is to complete the task of bringing these together in order to collect gas separately, Professor Belcher said.

The study, published in the journal Nature Nanotechnology, is only the first stage of a much longer process of development. In addition to refining the hydrogensplitting part of the reaction, the scientists still have a long way to go to increase the efficiency at which sunlight is converted into chemical energy. Nevertheless, Professor Belcher predicted that it should be possible to develop the idea into a prototype commercial product that can carry out the entire watersplitting process in a durable, selfsustaining way within two years.

Professor Thomas Mallouk of Pennsylvania State University, said the research was an extremely clever piece of work that addressed one of the most difficult problems in artificial photosynthesis by organizing molecular components in a manner that could control the critical transfer of electrons, just like real photosynthesis.

He said: There is a daunting combination of problems to be solved before this or any other artificial photosynthetic system could be useful for energy conversion. For a start, it needs to be at least 10 times more efficient than natural photosynthesis, to use less expensive material and to be able to repeat chemical reactions over and over, billions of times.

Professor Mallouk said: This is unlikely to happen in the near future. Nevertheless, the design idea illustrated in this [study] could ultimately help with an important piece of the puzzle.

How Ukraine Will Keep the Lights On This Winter

Ukraine Winter Energy Strategy strengthens the power grid through infrastructure repairs, electricity imports, renewable integration, nuclear output, and conservation to ensure reliable heating, blackout mitigation, and grid resilience with international aid, generators, and transmission lines.

 

Key Points

A wartime plan to stabilize Ukraine's grid via repairs, imports, renewables, and nuclear to deliver reliable electricity.

✅ Repairs, imports, and demand management stabilize the grid.

✅ Renewables and nuclear reduce outage risks in winter.

✅ International aid supplies transformers, generators, expertise.

 

As Ukraine braces for the winter months, the question of how the country will keep the lights on has become a pressing concern, as the country fights to keep the lights on amid ongoing strikes. The ongoing war with Russia has severely disrupted Ukraine's energy infrastructure, leading to widespread damage to power plants, transmission lines, and other critical energy facilities. Despite these challenges, Ukraine has been working tirelessly to maintain its energy supply during the cold winter months, which are essential not only for heating but also for the functioning of homes, businesses, hospitals, and schools. Here's a closer look at the steps Ukraine is taking to keep the lights on this winter and ensure that its people have access to reliable electricity.

1. Repairing Damaged Infrastructure

One of the most immediate concerns for Ukraine's energy sector is the extensive damage inflicted on its power infrastructure by Russian missile and drone attacks. Since the war began in 2022, Ukraine has faced repeated attacks targeting power plants, substations, and power lines, including strikes on western regions that caused widespread outages across communities. These attacks have left parts of the country with intermittent or no electricity, and repairing the damage has been a monumental task.

However, Ukraine has made significant progress in restoring its energy infrastructure. Government agencies and energy companies have been working around the clock to repair power plants and transmission networks. Teams of technicians and engineers have been deployed to restore power to areas that have been hardest hit by Russian attacks, often under difficult and dangerous conditions. While some areas may continue to face outages, efforts to rebuild the energy grid are ongoing, with the government prioritizing critical infrastructure to ensure that hospitals, military facilities, and essential services have access to power.

2. Energy Efficiency and Conservation Measures

To cope with reduced energy availability and avoid overloading the grid, Ukrainian authorities have been encouraging energy efficiency and conservation measures. These efforts are particularly important during the winter when demand for electricity and heating is at its peak.

The government has implemented energy-saving programs, urging citizens and businesses to reduce their consumption and adopt new energy solutions that can be deployed quickly. Measures include limiting electricity use during peak hours, setting thermostats lower in homes and businesses, and encouraging the use of energy-efficient appliances. Ukrainian officials have also been promoting public awareness campaigns to educate people about the importance of energy conservation, which is crucial to avoid grid overload and ensure the distribution of power across the country.

3. Importing Energy from Abroad

To supplement domestic energy production, Ukraine has been working to secure electricity imports from neighboring countries. Ukraine has long been interconnected with energy grids in countries such as Poland, Slovakia, and Hungary, which allows it to import electricity during times of shortage. In recent months, Ukraine has ramped up efforts to strengthen these connections, ensuring that it can import electricity when domestic production is insufficient to meet demand, and in a notable instance, helped Spain during blackouts through coordinated cross-border support.

While electricity imports from neighboring countries provide a temporary solution, this is not without its challenges. The cost of importing electricity can be high, and the country’s ability to import large amounts of power depends on the availability of energy in neighboring nations; officials say there are electricity reserves and no scheduled outages if strikes do not resume. Ukraine has been actively seeking new energy partnerships and working with international organizations to secure access to electricity, including exploring the potential for importing energy from the European Union.

4. Harnessing Renewable Energy Sources

Another key part of Ukraine's strategy to keep the lights on this winter is tapping into renewable energy sources, particularly wind and solar power. While Ukraine’s energy sector has historically been dependent on fossil fuels, the country has been making strides in integrating renewable energy into its grid. Solar and wind energy are particularly useful in supplementing the national grid, especially during the winter months when demand is high.

Renewable energy sources are less vulnerable to missile strikes compared to traditional power plants, making them an attractive option for Ukraine's energy strategy. Although renewable energy currently represents a smaller portion of Ukraine’s overall energy mix, its contribution is expected to increase as the country invests more in clean energy infrastructure. In addition to reducing dependence on fossil fuels, this shift is aligned with Ukraine’s broader environmental goals and will be important for the long-term sustainability of its energy sector.

5. International Aid and Support

International support has been crucial in helping Ukraine keep the lights on during the war. Western allies, including the European Union and the United States, have provided financial assistance, technical expertise, and equipment to help restore the energy infrastructure, though Washington recently ended some grid restoration support as priorities shifted. In addition to rebuilding power plants and transmission lines, Ukraine has received advanced energy technologies and materials to strengthen its energy security.

The U.S. has sent electrical transformers, backup generators, and other essential equipment to help Ukraine restore its energy grid. The European Union has also provided both financial and technical assistance, supporting Ukraine’s efforts to integrate more renewable energy into its grid and enhancing the country’s ability to import electricity from neighboring states.

6. The Role of Nuclear Energy

Ukraine’s nuclear energy plants play a critical role in the country’s electricity supply. Before the war, nuclear power accounted for around 50% of Ukraine’s total electricity generation, and for communities near the front line, electricity is civilization that depends on reliable baseload. Despite the ongoing conflict, Ukrainian nuclear plants have remained operational, though they face heightened security risks due to the proximity of active combat zones.

In the winter months, nuclear plants are expected to continue providing a significant portion of Ukraine's electricity, which is essential for meeting the country's heating and power needs. The government has made efforts to ensure the safety and security of these plants, which remain a vital part of the country's energy strategy.

Keeping the lights on in Ukraine during the winter of 2024 is no small feat, given the war-related damage to energy infrastructure, rising energy demands, and ongoing security risks. However, the Ukrainian government has taken proactive steps to address these challenges, including repairing critical infrastructure, importing energy from neighboring countries, promoting energy efficiency, and expanding renewable energy sources. International aid and the continued operation of nuclear plants also play a vital role in ensuring a reliable energy supply. While challenges remain, Ukraine’s resilience and determination to overcome its energy crisis are clear, and the country is doing everything it can to keep the lights on through this difficult winter.

Electricity rates are about to change across Ontario

Ontario Electricity Rate Changes lower OEB Regulated Price Plan costs, adjust Time-of-Use winter hours and tiered thresholds, and modify the Ontario Electricity Rebate, affecting off-peak, mid-peak, and on-peak pricing for households and small businesses.

 

Key Points

OEB updates lowering RPP prices, shifting TOU hours, adjusting tiers, and modifying the Ontario Electricity Rebate.

✅ Winter TOU: Off-peak 7 p.m.-7 a.m.; weekends, holidays all day.

✅ Tiered pricing adds 400 kWh at lower rate for residential users.

✅ Ontario Electricity Rebate falls to 11.7% from 17% on Nov 1.

 

Electricity rates are about to change for consumers across Ontario.

On November 1, households and small businesses will see their electricity rates go down under the Ontario Energy Board's (OEB) Regulated Price Plan framework.

Customer's on the OEB's tiered pricing plan will also see their bills lowered on November 1, a shift from the 2021 increase when fixed pricing ended, as winter time-of-use hours and the seasonal change in the killowatt-hour threshold take effect.

Off-peak time-of-use hours will run from 7 p.m. to 7 a.m. during weekdays, including the ultra-low overnight rates option for some customers, and all day on weekends and holidays. On-peak hours will be from 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. on weekdays, and mid-peak hours from 11 a.m. to 5 p.m. on weekdays.

The winter-tier threshold provides residential customers with an extra 400 kilowatt-hours per month at a lower price during the colder weather, alongside the off-peak price freeze in effect.

The Ontario Electricity Rebate - a pre-tax credit that shows up at the bottom of electricity bills - will also see changes as a hydro rate change takes effect on November 1. Starting next month, the rebate will drop from 17 per cent to 11.7 per cent.

For a typical residential customer, the credit will decrease electricity bills by about $13.91 per month, according to the OEB.

Under the board's winter disconnection ban, electricity providers can't turn off a residential customer's power between November 15, 2022 and April 30, 2023 for failing to pay, and earlier pandemic relief included a fixed COVID-19 hydro rate for customers.

China's electric power woes cast clouds on U.S. solar's near-term future

China Power Rationing disrupts the solar supply chain as coal shortages, price controls, and dual-control emissions policy curb electricity, squeezing polysilicon, aluminum, and module production and raising equipment costs amid surging post-Covid industrial demand.

 

Key Points

China's electricity curbs from coal shortages, price caps, and emissions targets disrupt solar output and materials.

✅ Polysilicon and aluminum output cut by power rationing

✅ Coal price spikes and power price caps squeeze generators

✅ Dual-control emissions policy triggers provincial curbs

 

The solar manufacturing supply chain is among the industries being affected by a combination of soaring power demand, coal shortages, and carbon emission reduction measures which have seen widespread power cuts in China.

In Yunnan province, in southwest China, producers of the silicon metal which feeds polysilicon have been operating at 10% of the output they achieved in August. They are expected to continue to do so for the rest of the year as provincial authorities try to control electricity demand with a measure that is also affecting the phosphorus industry.

Fellow solar supply chain members from the aluminum industry in Guangxi province, in the south, have been forced to operate just two days per week, alongside peers in the concrete, steel, lime, and ceramics segments. Manufacturers in neighboring Guangdong have access to normal power supplies only on Fridays and Saturdays with electricity rationed to a 15% grid security load for the rest of the time.

pv magazine USA reported that a Tier 1 solar module manufacturer warned customers in an email that energy shortages in China have forced it to reduce or stop production at its Chinese manufacturing sites. The company warned the event will also affect output from its downstream cell and module production facilities in Southeast Asia.

The memo said that in order to recover from the effects of the “potential Force Majeure event,” it may delay or stop equipment delivery or seek to renegotiate contracts to pass through higher prices.

Raw material sourcing
With reports of drastic power shortages emerging from China in recent days, the country has actually been experiencing problems since late June, and similar pressures have seen India ration coal supplies this year, but rationing is not unusual during the peak summer hours.

What has changed this time is that the outages have continued and prompted rationing measures across 19 of the nation’s provinces for the rest of the year. The problems have been caused by a combination of rising post-Covid electricity demand at a time when the politically-motivated ban on imports of Australian coal has tightened supply; and the manner in which Beijing controls power prices, with the situation further exacerbated by carbon emissions reduction policy.

Demand
Electricity demand from industry, underscoring China’s electricity appetite, was 13.5 percentage points higher in the first eight months of the year than in the same period of 2020, at 3,585 TWh. That reflected a 13.8% year-on-year rise in total consumption, following earlier power demand drops when coronavirus shuttered plants, to 5.47 PWh, according to data from state energy industry trade body the China Electricity Council.

Figures produced by the China General Administration of Customs tell the same story: a rebound driven by the global recovery from the pandemic, as global power demand surges above pre-pandemic levels, with China recording import and export trade worth RMB2.48 trillion ($385 billion) in January-to-August. That was up 23.7% on the same period of last year and 22.8% higher than in the first eight months of 2019.

With Beijing having enforced an unofficial ban on imports of Australian coal for the last year or so – as the result of an ongoing diplomatic spat with Australia – rising demand for coal (which provided around 73% of Chinese electricity in the first half of the year) has further raised prices for the fossil fuel.

The problem for Chinese coal-fired power generators is that Beijing maintains strict controls on the price of electricity. As a result, input costs cannot be passed on to consumers. The mismatch between a liberalized coal market and centrally controlled end-user prices is illustrated by the current situation in Guangdong. There, a coal price of RMB1,560 per ton ($242) has pushed the cost of coal-fired electricity up to RMB0.472 per kilowatt-hour ($0.073). With coal power companies facing an electricity price ceiling of around RMB0.463/kWh ($0.071), generators are losing around RMB0.12 for every kilowatt-hour they generate. In that situation, rationing electricity supplies is an obvious remedy.

The crisis has been worsened by the introduction of China’s “dual control” energy policy, which aims to help meet President Xi Jinping’s climate change pledge of hitting peak carbon emissions this decade and a net zero economy by 2060, and to reduce coal power production over time. Dual control refers to attempts to wind down greenhouse gas emissions at both a national level and in more local areas, such as provinces and cities.

Red status
With the finer details of the carbon reduction policy yet to be ironed out, government departments and provincial and city authorities have started to set their own emission-reduction targets. In mid-August, state planning body the China National Development and Reform Commission (NDRC) published a table of the energy control situation across the nation. With nine provinces marked red for their energy consumption, and a further 10 highlighted as yellow, officials received another motivation to introduce power rationing.

The current approach of rolling blackouts seems unlikely to be a sustainable solution, as surging electricity demand strains power systems worldwide, given the damage it could inflict on industry and the resentment it would cause in parts of the nation already preparing for winter.

The choice facing China’s policymakers is whether to ramp up coal supplies to force prices down by using decommissioned domestic supplies and halting the ban on Australian imports, or to raise electricity prices to prompt generators to get the lights back on. While the drawbacks of raising household electricity bills seem obvious, the first approach of using more coal could endanger the nation’s climate change commitments on the even of the COP26 meeting in Glasgow, Scotland, in November. Sources close to the NDRC have suggested the electricity price may be set to rise soon.

GDP
What is clear is the effect the energy crisis is having on the Chinese economy and on the solar supply chain. Leading up to a  national day holiday in China, the coal price in northern China rose to around RMB2,000 per ton ($310), three times higher than at the beginning of the year.

Investment bank China International Capital Corp. blamed the dual control emission reduction policy for the electricity shortages. It predicted a 0.1-0.15 percentage point impact on economic growth in the last quarter of 2021.  Morgan Stanley has put that figure at 1% in the current quarter, if industrial output restrictions continue. And Japan’s Nomura Securities revised down its annual forecast on Chinese growth from 8.2% to 7.7%. It now expects GDP gains in the third and fourth quarters to cool from 5.1% to 4.7%, and from 4.4% to 3%, respectively.

New clean energy investment in developing nations slipped sharply last year: report

Developing Countries Clean Energy investment fell as renewable energy financing slowed in China; solar and wind growth lagged while coal power hit new highs, raising emissions risks for emerging markets and complicating climate change goals.

 

Key Points

Renewables investment and power trends in emerging nations: solar, wind, coal shifts, and steps toward decarbonization.

✅ Investment fell to $133b; China dropped to $86b

✅ Coal power rose to 6,900 TWh; 47% generation share

✅ New coal builds declined to 39 GW, decade low

 

New clean energy investment slid by more than a fifth in developing countries last year due to a slowdown in China, while the amount of coal-fired power generation jumped to a new high, reflecting global power demand trends, a recent annual survey showed.

Bloomberg New Energy Finance (BNEF) surveyed 104 emerging markets and found that developing nations were moving towards cleaner, low-emissions sources in many regions, but not fast enough to limit carbon dioxide emissions or the effects of climate change.

New investment in wind, solar and other clean energy projects dropped to $133 billion last year from $169 billion a year earlier, mainly due to a slump in Chinese investment, even as electricity investment globally surpasses oil and gas for the first time, the research showed.

China’s clean energy investment fell to $86 billion from $122 billion a year earlier, with dynamics in China's electricity sector also in focus. Investment by India and Brazil also declined, mainly due to lower costs for solar and wind.

However, the volume of coal-fired power generation produced and consumed in developing countries increased to a new high of 6,900 terrawatt hours (TWh) last year, even as renewables are poised to eclipse coal globally, from 6,400 TWh in 2017.

The increase of 500 TWh is equivalent to the power consumed in the U.S. state of Texas in one year, underscoring how surging electricity demand is putting power systems under strain. Coal accounted for 47% of all power generation across the 104 countries.

“The transition from coal toward cleaner sources in developing nations is underway,” said Ethan Zindler, head of Americas at BNEF. “But like trying to turn a massive oil tanker, it takes time.”

Despite the spike in coal-fired generation, the amount of new coal capacity which was added to the grid in developing countries declined, with Europe's renewables crowding out gas offering a contrasting pathway. New construction of coal plants fell to its lowest level in a decade last year of 39 gigawatts (GW).

The report comes a week ahead of United Nations climate talks in Madrid, Spain, where more than 190 countries will flesh out the details of an accord to limit global warming.

Nuclear helps Belgium increase electricity exports in 2019

Belgium Energy Mix 2019 shows strong nuclear output, rising offshore wind, net electricity exports, and robust interconnections, per Elia, as the nuclear phaseout drives 3.9GW new capacity needs after improved reactor availability.

 

Key Points

High nuclear share, offshore wind, net exports, interconnections; 3.9GW capacity needed amid nuclear phaseout.

✅ Nuclear supplied 48.8% of generation in 2019.

✅ Net exporter: 1.8 TWh, aided by interconnections.

✅ Elia projects 3.9GW new capacity for phaseout.

 

Belgium's electricity transmission system operator, Elia, said that the major trends in 2019 were a steady increase in (mainly offshore) renewable power generation, illustrated by EU wind and solar records across the bloc, better availability of nuclear-generating facilities and an increase in electricity exports.

In 2019, 48.8% of the power generated in Belgium came from nuclear plants. This was in line with the total for 2017 (50%) and significantly more than in 2018 (31.2%) when several reactors were unavailable amid stunted hydro and nuclear output in Europe as well.

Belgium exported more electricity in 2019, as neighbors like Germany saw renewables overtake coal and nuclear generation, with net exports of 1.8TWh (2.1% of the energy mix), in contrast to 2018 when Belgium imported 17.5TWh (20%).

Elia said this “should be viewed in its wider context, of declining nuclear capacity in Europe and regional market shifts, against the backdrop of an increasingly Europeanised market, and can be explained primarily by the good availability of Belgium's generating facilities (especially its nuclear power stations).”

The development of interconnections was also a key factor in the circulation of these electricity flows, as seen with Irish grid price spikes highlighting regional stress, Elia noted.

“Belgium had not been a net exporter of electricity for almost 10 years, the last time being in 2009 and 2010, when total net exports represented 2.8% and 0.2% respectively of Belgium’s energy mix,” it said.

Belgian has seven nuclear reactors – three at Tihange near Liege and four at Doel near Antwerp – and, regionally, nuclear-powered France faces outage risks that influence cross-border reliability.

In 2003, Belgium decided to phase out nuclear power and passed a law to that effect, with neighbors like Germany navigating a balancing act during their energy transition, which was reaffirmed in 2015 and 2018.

A commission appointed to assess the impact of the nuclear phaseout is scheduled to be completed in 2025 but has yet to report any findings.

Elia estimates that some 3.9GW of new power generating capacity will be needed to compensate for Belgium's nuclear phaseout.

China's Data Centers Alone Will Soon Use More Electricity Than All Of Australia

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

 

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

 

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."
