Voith Siemens' opens new workshop in Shanghai

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."

UK Marine Energy and Climate Resilience can counter sea level rise and storm surge with tidal power, subsea turbines, heat pumps, and flood barriers, delivering renewable electricity, stability, and coastal protection for the United Kingdom.

Key Points

Integrated use of tidal power, barriers, and heat pumps to curb sea level rise, manage storms, and green the UK grid.

✅ Tidal bridges and subsea turbines enhance baseload renewables

✅ Integrated barriers cut storm surge and river flood risk

✅ Heat pumps and marine heat networks decarbonize coastal cities

IN concentrating on electrically driven cars, the UK’s new ten-point energy plans, and recent UK net zero policies, ignores the elephant in the room.

It fails to address the forecast six-metre sea level rise from global warming rapidly melting the Greenland ice sheet.

Rising sea levels and storm surge, combined with increasingly heavy rainfall swelling our rivers, threaten not only hundreds of coastal communities but also much unprotected strategic infrastructure, including electricity systems that need greater resilience.

New nuclear power stations proposed in this United Kingdom plan would produce radioactive waste requiring thousands of years to safely decay.

This is hardly the solution for the Green Energy future, or the broader global energy transition, that our overlooked marine energy resource could provide.

Sea defences and barrier design, built and integrated with subsea turbines and heat pumps, can deliver marine-driven heat and power to offset the costs, not only of new Thames Barriers, but also future Severn, Forth and other barrages, while reducing reliance on high-GWP gases such as SF6 in switchgear across the grid.

At the Pentland Firth, existing marine turbine power could be enhanced by turbines deployed from new tidal bridges to provide much of UK’s electricity needs, as nations chart an electricity future that replaces fossil fuels, from its estimated 60 gigawatt capability.

Energy from Bluemull Sound could likewise be harvested and exported or used to enhance development around UK’s new space station at Unst.

The 2021 Climate Change Summit gives Glasgow the platform to secure Scotland’s place in a true green, marine energy future and help build an electric planet for the long term.

We must not waste this opportunity.

THERE is no vaccine for climate change.

It is, of course, wonderful news that such progress is being made in the development of Covid-19 vaccines but there is a risk that, no matter how serious the Covid crisis is, it is distracting attention, political will and resources from the climate crisis, a much longer term and more devastating catastrophe.

They are intertwined. As climate and ecological systems change, vectors and pathogens migrate and disease spreads.

What lessons can be learned from one to apply to the other?

Prevention is better than cure. We need to urgently address the climate crisis, charting a path to net zero electricity by the middle of the century, to help prevent future pandemics.

We are only as safe as the most vulnerable. Covid immunisation will protect the most vulnerable; to protect against the effects of climate change we need to look far more deeply. Global challenges require systemic change.

Neither Covid or climate change respect national borders and, for both, we need to value and trust science and the scientific experts and separate them from political posturing.

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.

eRex Biomass Power Plant will deliver 300 MW in Japan, offering stable baseload renewable energy, coal-cost parity, and feed-in tariff independence through economies of scale, efficient fuel procurement, and utility-scale operations supporting RE100 demand.

Key Points

A 300 MW Japan biomass project targeting coal-cost parity and FIT-free, stable baseload renewable power.

✅ 300 MW capacity; enough for about 700,000 households

✅ Aims to skip feed-in tariff via economies of scale

✅ Targets coal-cost parity with stable, dispatchable output

Power supplier eRex will build its largest biomass power plant to date in Japan, hoping the facility's scale will provide healthy margins, a strategy increasingly seen among renewable developers pursuing diverse energy sources, and a means of skipping the government's feed-in tariff program.

The Tokyo-based electric company is in the process of selecting a location, most likely in eastern Japan. It aims to open the plant around 2024 or 2025 following a feasibility study. The facility will cost an estimated 90 billion yen ($812 million) or so, and have an output of 300 megawatts -- enough to supply about 700,000 households. ERex may work with a regional utility or other partner

The biggest biomass power plant operating in Japan currently has an output of 100 MW. With roughly triple that output, the new facility will rank among the world's largest, reflecting momentum toward 100% renewable energy globally that is shaping investment decisions.

Nearly all biomass power facilities in Japan sell their output through the government-mediated feed-in tariff program, which requires utilities to buy renewable energy at a fixed price. For large biomass plants that burn wood or agricultural waste, the rate is set at 21 yen per kilowatt-hour. But the program costs the Japanese public more than 2 trillion yen a year, and is said to hamper price competition.

ERex aims to forgo the feed-in tariff with its new plant by reaping economies of scale in operation and fuel procurement. The goal is to make the undertaking as economical as coal energy, which costs around 12 yen per kilowatt-hour, even as solar's rise in the U.S. underscores evolving benchmarks for competitive renewables.

Much of the renewable energy available in Japan is solar power, which fluctuates widely according to weather conditions, though power prediction accuracy has improved at Japanese PV projects. Biomass plants, which use such materials as wood chips and palm kernel shells as fuel, offer a more stable alternative.

Demand for reliable sources of renewable energy is on the rise in the business world, as shown by the RE100 initiative, in which 100 of the world's biggest companies, such as Olympus, have announced their commitment to get 100% of their power from renewable sources. ERex's new facility may spur competition.

2040 Energy Outlook projects a shifting energy mix as renewables scale, EV adoption accelerates, and IEA forecasts plateauing oil demand alongside rising natural gas, highlighting policy, efficiency, and decarbonization trends that shape global consumption.

Key Points

A data-driven view of future energy mix, covering renewables, fossil fuels, EVs, oil demand, and policy impacts.

✅ Renewables reach 16-30% by 2040, higher with strong policy support.

✅ Fossil fuels remain dominant, with oil flat and natural gas rising.

✅ EV share surges, cutting oil use; efficiency curbs demand growth.

Which is more plausible: flying taxis, wind turbine arrays stretching miles into the ocean, and a solar roof on every house--or a scorched-earth, flooded post-Apocalyptic world? 

We have no way of peeking into the future, but we can certainly imagine it. There is plenty of information about where the world is headed and regardless of how reliable this information is—or isn’t—we never stop wondering. Will the energy world of 20 years from now be better or worse than the world we live in now? 

The answer may very well lie in the observable trends.

A Growing Population

The global population is growing, and it will continue to grow in the next two decades. This will drive a steady growth in energy demand, at about 1 percent per year, according to the International Energy Agency.

This modest rate of growth is good news for all who are concerned about the future of the planet. Parts of the world are trying to reduce their energy consumption, and this should have a positive effect on the carbon footprint of humanity. The energy thirst of most parts of the world will continue growing, however, hence the overall growth.

The world’s population is currently growing at a rate of a little over 1 percent annually. This rate of growth has been slowing since its peak in the 1960s and forecasts suggest that it will continue to slow. Growth in energy demand, on the other hand, may at some point stop moving in tune with population growth trends as affluence in some parts of the world grows. The richer people get, the more energy they need. So, to the big question: where will this energy come from?

The Rise of Renewables

For all the headline space they have been claiming, it may come as a disappointing surprise to many that renewable energy, excluding hydropower, to date accounts for just 14 percent of the global primary energy mix. 

Certainly, adoption of solar and wind energy has been growing in leaps and bounds, with their global share doubling in five years in many markets, but unless governments around the world commit a lot more money and effort to renewable energy, by 2040, solar and wind’s share in the energy mix will still only rise to about 16 to 17 percent. That’s according to the only comprehensive report on the future of energy that collates data from all the leading energy authorities in the world, by non-profit Resources for the Future.

The growth in renewables adoption, however, would be a lot more impressive if governments do make serious commitments. Under that scenario, the share of renewables will double to over 30 percent by 2040, echoing milestones like over 30% of global electricity reached recently: that’s the median rate of all authoritative forecasts. Amongst them, the adoption rates of renewables vary between 15 percent and 61 percent by 2040.

Even the most bullish of the forecasts on renewables is still far below the 100-percent renewable future many would like to fantasize about, although BNEF’s 50% by 2050 outlook points to what could be possible in the power sector. 

But in 2040, most of the world’s energy will still come from fossil fuels.

EV Energy

Here, forecasters are more optimistic. Again, there is a wide variation between forecasts, but in each and every one of them the share of electric vehicles on the world’s roads in 2040 is a lot higher than the meagre 1 percent of the global car fleet EVs constitute today.
Related: Gas Prices Languish As Storage Falls To Near-Record Lows

Government policy will be the key, as U.S. progress toward 30% wind and solar shows how policy steers the power mix that EVs ultimately depend on. Bans of internal combustion engines will go a long way toward boosting EV adoption, which is why some forecasters expect electric cars to come to account for more than 50 percent of cars on the road in 2040. Others, however, are more guarded in their forecasts, seeing their share of the global fleet at between 16 percent and a little over 40 percent.

Many pin their hopes for a less emission-intensive future on electric cars. Indeed, as the number of EVs rises, they displace ICE vehicles and, respectively, the emission-causing oil that fuels for ICE cars are made from.  It should be a no brainer that the more EVs we drive, the less emissions we produce. Unfortunately, this is not necessarily the case: China is the world’s biggest EV market, and its solar PV expansion has been rapid, it has the most EVs—including passenger cars and buses—but it is also one of the biggest emitters.

Still, by 2040, if the more optimistic forecasts come true, the world will be consuming less oil than it is consuming now: anywhere from 1.2 million bpd to 20 million bpd less, the latter case envisaging an all-electric global fleet in 2040. 

This Ain’t Your Daddy’s Oil

No, it ain’t. It’s your grandchildren’s oil, for good or for bad. The vision of an oil-free world where renewable power is both abundant and cheap enough to replace all the ways in which crude oil and natural gas are used will in 2040 still be just that--a vision, with practical U.S. grid constraints underscoring the challenges. Even the most optimistic energy scenarios for two decades from now see them as the dominant source of energy, with forecasts ranging between 60 percent and 79 percent. While these extremes are both below the over-80 percent share fossil fuels have in the world’s energy mix, they are well above 50 percent, and in the U.S. renewables are projected to reach about one-fourth of electricity soon, even as fossil fuels remain foundational.

Still, there is good news. Fuel efficiency alone will reduce oil demand significantly by 2040. In fact, according to the IEA, demand will plateau at a little over 100 million bpd by the mid-2030s. Combined with the influx of EVs many expect, the world of 20 years from now may indeed be consuming a lot less oil than the world of today. It will, however, likely consume a lot more natural gas. There is simply no way around fossil fuels, not yet. Unless a miracle of politics happens (complete with a ripple effect that will cost millions of people their jobs) in 2040 we will be as dependent on oil and gas as we are but we will hopefully breathe cleaner air.

Lockdown Electricity Demand Trends reveal later mornings, weaker afternoons, and delayed peaks as WFH, streaming, and video conferencing reshape energy demand curves, grid forecasting, and residential electricity usage across Europe, New York, Tokyo, and Singapore.

Key Points

Shifts in power use during lockdowns: later ramps, weaker afternoons, and higher, delayed evening peaks.

✅ Morning ramp starts later; midday demand dips

✅ Evening peak shifts 1-2 hours; higher late-night usage

✅ WFH and streaming raise residential load; industrial demand falls

Life in lockdown means getting up late, staying up till midnight and slacking off in the afternoons.

That’s what power market data in Europe show in the places where restrictions on activity have led to a widespread shift in daily routines of hundreds of millions of people.

It’s a similar story wherever lockdowns bite. In New York City electricity use has fallen as much as 18% from normal times at 8am. Tokyo and three nearby prefectures had a 5% drop in power use during weekdays after Japan declared a state of emergency on April 7, according to Tesla Asia Pacific, an energy forecaster.

Italy’s experience shows the trend most clearly since the curbs started there on March 5, before any other European country. Data from the grid operator Terna SpA gives a taste of what other places are also now starting to report, with global daily demand dips observed in many markets as well.

1. People are sleeping later

With no commute to the office people can sleep longer. Normally, electricity demand began to pick up between 6 a.m. and 8 a.m. Now in Germany, it’s clear coffee machines don’t go on until between 8 a.m. and 9 a.m., said Simon Rathjen, founder of the trading company MFT Energy A/S.

Germany, France and Italy -- which between them make up almost two thirds of the euro-zone economy -- all have furlough measures that allow workers to receive a salary while temporarily suspended from their jobs. The U.K. also has a support package. Many of these workers will be getting up later.

"Now I have quite a relaxed start to the morning,” said David Freeman, an analyst in financial services from London. "I don’t get up until about half an hour before I need to start work.”

2. Less productive afternoons

There is a deeper dip in electricity use in the afternoons. Previously, power use rose between 2pm and 5pm. Now it dips as people head out for a walk or some air, according to UK demand data from National Grid Plc

It’s "as though we are living through a month of Sundays”, said Iain Staffell, senior lecturer in sustainable energy at Imperial College London.

3. Evenings in

From 6pm electricity use begins to rise steeply as people finish work and start chores. Restrictions like work and home schooling that prevent much daytime TV watching lifts in the early evening. This following chart for Germany shows the evening peak for power use coming during later hours.

The evening is when electricity use is highest, with most people confined to their homes. Netflix Inc reported a record 15.8 million paid subscribers – almost double the figure forecast by Wall Street analysts. Video-streaming services like Netflix and YouTube have found a captive audience. The new Disney+ service surpassed 50 million subscribers in just five months, a faster pace than predicted.

Internet traffic is skyrocketing, with a surge in bandwidth-intensive applications like streaming services and Zoom. This may mean that monthly broadband consumption of as much as 600 gigabytes, about 35% higher than before, according to Bloomberg Intelligence.

In Singapore, electricity use has dropped off significantly since the country’s "circuit-breaker” efforts to keep people at home began April 7. Electricity use has fallen and stayed low during the day. But late at night is a different story, as power demand fell sharply immediately after the lockdown began, it has steadily crept back in the past two weeks, perhaps a sign that Tiger King and The Last Dance have been finding late-night fans in the city state.

In Ottawa, COVID-19 closures made it seem as if the city had fallen off the electricity grid, according to local reports.

4. Staying up late

We’re going to bed later too. Demand doesn’t start to drop off until 10pm to 12am, at least an hour later than before.

"My children are definitely going to bed later,” said Liz Stevens, a teaching assistant from London. "Our whole routine is out the window.”

It’s challenging for those that need to predict behaviour – power grids and electricity traders. Forecasting is based on historical data, and there isn’t anything to go into the models gauging use now.

The closest we can get is looking at big events like football World Championships when people are all sitting down at the same time, according to Rathjen at MFT.

"Forecasting demand right now is very tricky,” said Chris Kimmett, director of power grids at Reactive Technologies Ltd. "A global pandemic is uncharted territory."

What normal looks like when the crisis passes is also an open question. Different countries are set to unravel their measures in their own ways, and global power demand has already surged above pre-pandemic levels in some analyses, with Germany and Austria loosening restrictions first and Italy remaining under tight control. Some changes may be permanent, with both workers and employers becoming more comfortable with working from home.

5. Different sectors consume more

In China, which is further along recovering from the pandemic than Europe or the US, the sharp contraction in overall power output masks a shift in daily routines.

Eating habits have changed. Restaurants are expanding delivery and even offering grocery services as the preference for dining at home persists. Household electricity consumption in China probably increased from activities such as cooking and heating, according to IHS Markit, which said that residential demand rose by 2.4% in the first two months as people stayed in.

The increase in technology use also drove China’s power demand from the telecom and web-service sectors to rise by 27%, the consultancy said.

Overall, China power demand in the first quarter of the year fell 6.5% from the same period in 2019 to 1.57 trillion kilowatt-hours, China’s National Energy Administration said last week. Industry uses about 70% of the country’s electricity, while the commercial sector and households account for 14% each. – Bloomberg
