Hewlett-Packard (HP) is getting more detailed in how it analyzes the energy efficiency of its customers' datacenters.

HP introduced Thermal Zone Mapping, a new feature of its HP Services business that calculates how to improve server cooling while keeping electric bills down.

HP Services already analyzes datacenters by physically inspecting them and producing two-dimensional thermal photographs that show hot spots in red and cool spots in blue. It also creates three-dimensional photos that highlight airflow patterns from air conditioning vents and around server racks.

Thermal Zone Mapping goes beyond that with computer modeling, allowing datacenter managers to run scenarios, testing the effect on cooling demand of moving server racks or air conditioning vents to different locations. The mapping identifies "zones of influence" where the air is coldest, for example, said Brian Brouillette, vice president, of HP mission-critical, network, and education services within HP Services.

The mapping may show that one area is cooler than the rest of the room because it gets air from three air conditioning vents. "Maybe that's where I should be putting my most mission-critical servers... because it's got three times redundancy," Brouillette said. "(Planning) is no longer random."

HP is one of many technology companies touting energy-efficient products, services, or corporate commitment to green technology.

A 2006 survey of IT professionals by IDC showed that about one-fifth of them cited power and cooling as the number one issue they face in their datacenters, a greater proportion than cited disaster recovery, security, staffing, or any other issue.

Datacenters in the United States use 59 billion kilowatt hours of electricity per year, costing $4.1 billion and generating 864 million metric tons of carbon dioxide (CO2) emissions, said Thomas Goepel, program manager for adaptive infrastructure solutions in the HP Technology Solutions Group.

The mapping tool announcement follows another HP service unveiled in November 2006, Dynamic Smart Cooling (DSC). With DSC, small temperature monitors attached to each server rack detect if the temperature is rising because the server is doing more computations and increases the air conditioning aimed at that rack. When the server workload goes down, the air conditioning is dialed back. Wachovia Bank is testing a DSC installation at one of its datacenters, HP said.

IBM unveiled its Project Big Green initiative May 10, pledging to spend $1 billion every year to improve the energy efficiency of corporate datacenters.

Also, processor maker Advanced Micro Devices said it has surpassed goals it set in 2001 for reducing CO2 emissions and electricity usage at its own facilities. AMD set a goal of reducing CO2 by 40 percent but reached 50 percent at the end of 2006, and reduced electricity use by 40 percent, a third more than its 30 percent goal, said Steve Groseclose, director of global environmental health and safety at AMD.

AMD has set new goals to reduce CO2 emissions by another 33 percent and electrical usage by another 40 percent by 2010.

US Electricity Prices Rise Most in 41 Years as Inflation Endures

US Electricity Price Surge drives bills as BLS data show 15.8 percent jump; natural gas and coal costs escalate amid energy crisis, NYISO warns of wholesale prices and winter futures near $200 per MWh.

 

Key Points

A sharp rise in power bills driven by higher natural gas and coal costs and tighter wholesale markets.

✅ BLS reports electricity bills up 15.8% year over year

✅ Natural gas bills up 33% as fuel costs soar

✅ NYISO flags winter wholesale prices near $200/MWh

 

Electricity bills for US consumers jumped the most since 1981, gaining 15.8% from the same period a year ago, according to the US Bureau of Labor Statistics, and residential bills rose 5% in 2022 across the U.S.

Natural gas bills, which crept back up last month after dipping in July, surged 33% from the same month last year, labor data released Tuesday showed, as electricity and natural gas pricing dynamics continue to ripple through markets. Broader energy costs slipped for a second consecutive month because of lower gasoline and fuel oil prices. Even with that drop, total energy costs were still about 24% above August 2021 levels.

Electricity costs are relentlessly climbing because prices for the two biggest power-plant fuels -- natural gas and coal -- have surged in the last year as the US economy rebounds from the pandemic and as Russia’s war in Ukraine triggers an energy crisis in Europe, where German electricity prices nearly doubled over a year. Another factor is the hot and humid summer across most of the lower 48 states drove households and businesses to crank up air conditioners. Americans likely used a record amount of power in the third quarter, according to US Energy Information Administration projections, even as U.S. power demand is seen sliding 1% in 2023 on milder weather.

New York’s state grid operator warned of a “sharp rise in wholesale electric costs expected this winter” with spiking global demand for fossil fuels, lagging supply and instability from Russia’s war in Ukraine driving up oil and gas prices, with multiple energy-crisis impacts on U.S. electricity and gas still unfolding, according to a Tuesday report. Geopolitical factors are ultimately reflected in wholesale electricity prices and supply charges to consumer bills, the New York Independent System Operator said, and as utilities direct more spending to delivery rather than production.

Electricity price futures for this winter have increased fourfold from last year, and potential deep-freeze disruptions to the energy sector could add volatility, with prices averaging near $200 a megawatt-hour, the grid operator said. That has been driven by natural gas futures for the upcoming winter, which are more than double current prices to nearly $20 per million British thermal units.

UK to End Coal Power After 142 Years

UK Coal Phase-Out signals an energy transition, accelerating decarbonization with offshore wind, solar, and storage, advancing net-zero targets, cleaner air, and a just transition for communities impacted by fossil fuel decline.

 

Key Points

A policy to end coal power in the UK, boosting renewables and net-zero goals while improving air quality.

✅ Coal electricity fell from 40% in 2012 to under 3% by 2022

✅ Offshore wind and solar expand capacity; storage enhances reliability

✅ Just transition funds retrain workers and support coal regions

 

The United Kingdom is poised to mark a significant milestone in its energy history by phasing out coal power entirely, ending a reliance that has lasted for 142 years. This decision underscores the UK’s commitment to combating climate change and transitioning toward cleaner energy sources, reflecting a broader global energy transition away from fossil fuels. As the country embarks on this journey, it highlights both the achievements and challenges of moving towards a sustainable energy future.

A Historic Transition

The UK’s relationship with coal dates back to the Industrial Revolution, when coal was the backbone of its energy supply, driving factories, trains, and homes. However, as concerns over air quality and climate change have mounted, the nation has progressively shifted its focus toward renewable energy sources amid a global decline in coal-fired electricity worldwide. The decision to end coal power represents the culmination of this transformation, signaling a definitive break from a past heavily reliant on fossil fuels.

In recent years, the UK has made remarkable strides in reducing its carbon emissions. From 2012 to 2022, coal's contribution to the country's electricity generation plummeted from around 40% to less than 3%, as policies like the British carbon tax took effect across the power sector. This dramatic decline is largely due to the rise of renewable energy sources, such as wind, solar, and hydroelectric power, which have increasingly filled the gap left by coal.

Environmental and Health Benefits

The move away from coal power has significant environmental benefits. Coal is one of the most carbon-intensive energy sources, releasing substantial amounts of carbon dioxide (CO2) and other harmful pollutants into the atmosphere. By phasing out coal, the UK aims to significantly reduce its greenhouse gas emissions and improve air quality, which has been linked to serious health issues such as respiratory diseases and cardiovascular problems.

The UK government has set ambitious net zero policies, aiming to achieve net-zero carbon emissions by 2050. Ending coal power is a critical step in reaching this target, demonstrating leadership on the global stage and setting an example for other countries still dependent on fossil fuels. This transition not only addresses climate change but also promotes a healthier environment for future generations.

The Role of Renewable Energy

As the UK phases out coal, renewable energy sources are expected to play a central role in meeting the country's energy needs. Wind power, in particular, has surged in prominence, with the UK leading the world in offshore wind capacity. In 2020, wind energy surpassed coal for the first time, accounting for over 24% of the country's electricity generation.

Solar energy has also seen significant growth, contributing to the diversification of the UK’s energy mix. The government’s investments in renewable energy infrastructure and technology have facilitated this rapid transition, providing the necessary framework for a sustainable energy future.

Economic Implications

While the transition away from coal power presents environmental benefits, it also carries economic implications. The coal industry has historically provided jobs and economic activity, particularly in regions where coal mining was a mainstay, a dynamic echoed in analyses of the decarbonization of Canada's electricity grid and its regional impacts. As the UK moves toward a greener economy, there is an urgent need to support communities that may be adversely affected by this transition.

To address potential job losses, the government has emphasized the importance of investing in retraining programs and creating new opportunities in the renewable energy sector. This will be vital in ensuring a just transition that supports workers and communities as the energy landscape evolves.

Challenges Ahead

Despite the progress made, the journey toward a coal-free UK is not without challenges. One significant concern is the need for reliable energy storage solutions to complement intermittent renewable sources like wind and solar. Ensuring a stable energy supply during periods of low generation will be critical for maintaining grid reliability.

Moreover, public acceptance and engagement will be crucial, as illustrated by debates over New Zealand's electricity transition and its pace, as the UK navigates this transition. Engaging communities in discussions about energy policies and developments can foster understanding and support for the changes ahead.

Looking to the Future

The UK’s decision to phase out coal power after 142 years marks a significant turning point in its energy policy and environmental strategy. This historic shift not only aligns with the country’s climate goals but also showcases its commitment to a cleaner, more sustainable future.

As the UK continues to invest in renewable energy and transition away from fossil fuels, it sets an important example for other nations, including those on China's path to carbon neutrality, grappling with similar challenges. By embracing this transition, the UK is not only addressing pressing environmental concerns but also paving the way for a greener economy that can thrive in the decades to come.

Electricity Shut-Offs in a Pandemic: How COVID-19 Leads to Energy Insecurity, Burdensome Bills

COVID-19 Energy Burden drives higher electricity bills as income falls, intensifying energy poverty, utility shut-offs, and affordability risks for low-income households; policy moratoriums, bill relief, and efficiency upgrades are vital responses.

 

Key Points

The COVID-19 energy burden is the rising share of income spent on energy as bills increase and earnings decline.

✅ Rising home demand and lost wages increase energy cost share.

✅ Mandated shut-off moratoriums and reconnections protect health.

✅ Fund assistance, efficiency, and solar for LMI households.

 

I have asthma. It’s a private piece of medical information that I don’t normally share with people, but it makes the potential risks associated with exposure to the coronavirus all the more dangerous for me. But I’m not alone. 107 million people in the U.S. have pre-existing medical conditions like asthma and heart disease; the same pre-existing conditions that elevate their risk of facing a life-threatening situation were we to contract COVID-19. There are, however, tens of millions more house-bound Americans with a condition that is likely to be exacerbated by COVID-19: The energy burden.

The energy burden is a different kind of pre-existing condition:
In the last four weeks, 22 million people filed for unemployment. Millions of people will not have steady income (or the healthcare tied to it) to pay rent and utility bills for the foreseeable future which means that thousands, possibly millions of home-bound Americans will struggle to pay for energy.

Your energy burden is the amount of your monthly income that goes to paying for energy, like your monthly electric bill. So, when household energy use increases or income decreases, your energy burden rises. The energy burden is not a symptom of the pandemic and the economic downturn; it is more like a pre-existing condition for many Americans.

Before the coronavirus outbreak, I shared a few maps that showed how expensive electricity is for some. The energy burden in most pronounced in places already struggling economically, like in Appalachia, where residents in some counties must put more than 30 percent of their income toward their electric bills, and in the Midwest where states such as Michigan have some families spending more than 1/5 of their income on energy bills. The tragic facts are that US families living below the poverty line are far more likely to also be suffering from their energy burden.

But like other pre-existing conditions, the impacts of the coronavirus pandemic are exacerbating the underlying problems afflicting communities across the country.

Critical responses to minimize the spread of COVID-19 are social distancing, washing hands frequently, covering our faces with masks and staying at home. More time at home for most will drive up energy bills, and not by a little. Estimates on how much electricity demand during COVID-19 will increase vary but I’ve seen estimates as high as a 20% increase on average. For some families that’s a bag of groceries or a refill on prescription medication.

What happens when the power gets turned off?
Under normal conditions, if you cannot pay your electric bill your electricity can get turned off. This can have devastating consequences. Most states have protections for health and medical reasons and some states have protections during extreme heat or cold weather. But enforcement of those protections can vary by utility service area and place unnecessary burdens on the customer.

UCS
Only Florida has no protections of any kind against utility shut-offs when health or medical reasons would merit protection against it. However, when it comes to protection against extreme heat, only a few states have mandatory protections based on temperature thresholds.

The NAACP has also pointed out that utilities have unceremoniously disconnected the power of millions of people, disproportionally African-American and Latinx households.

April tends to be a mild month for most of the country, but the South already had its first heat wave at the end of March. If this pandemic lasts into the summer, utility disconnects could become deadly, and efforts to prevent summer power outages will be even more critical to public health. In the summer, during extreme summer heat families can’t turn off the A/C and go to the movies if we are following public health measures and sheltering in place. Lots of families that don’t have or can’t afford to run A/C would otherwise gather at local community pools, beaches, or in cooling centers, but with parks, pools and community groups closed to prevent the virus’s spread, what will happen to these families in July or August?

But we won’t have to wait till the summer to see how families will be hard hit by falling behind on bills and losing power. Here are a few ways electricity disconnection policies cause people harm during the pandemic:

Loss of electricity during the COVID-19 pandemic means families will lose their ability to refrigerate essential food supplies.
Child abuse guidance discusses how unsanitary household conditions are a contributing factor to child protective services involvement. Unsanitary household conditions can include, for example, rotting food (which might happen if electricity is cut off).

HUD’s handbook on federally subsidized housing includes a chapter on termination, which says that lease agreements can be terminated for repeated minor infractions including failing to pay utilities.
Airway machines used to treat respiratory ailments—pre-existing conditions in this pandemic—will not work. Our elderly neighbors in particular might rely on medicine that requires refrigeration or medical equipment that requires electricity. They too have fallen victim to utility shut-offs even during the pandemic.

Empowering solutions are available today

Decisionmakers seeking solutions can look to implement utility shut off moratoriums as a good start. Good news is that many utilities have voluntarily taken action to that effect, and New Jersey and New York have suspended shut-offs, one of the best trackers on who is taking what action has been assembled by Energy Policy Institute.

But voluntary actions do not always provide comprehensive protection, and they certainly have not been universally adopted across the country. Some utilities are waiving fees as relief measures, and some moratoriums only apply to customers directly affected by COVID-19, which will place additional onerous red tape on households that are stricken and perhaps unable to access testing. Others might only be an extension of standard medical shut off protections. Moratoriums put in place by voluntary action can also be revoked or lifted by voluntary action, which does not provide any sense of certainty to people struggling to make ends meet.

This is why the US needs mandatory moratoriums on all utility disconnections. These normally would be rendered at the state level, either by a regulatory commission, legislative act, or even an emergency executive order. But the inconsistent leadership among states in response to the COVID-19 crisis suggests that Congressional action is needed to ensure that all vulnerable utility customers are protected. That’s exactly what a coalition of organizations, including UCS, is calling for in future federal aid legislation. UCS has called for a national moratorium on utility shut-offs.

And let’s be clear, preventing new shut-offs isn’t enough. Cutting power off at residence during a pandemic is not good public policy. People who are without electricity should have it restored so residents can safely shelter in place and help flatten the curve. So far, only Colorado and Wisconsin’s leadership has taken this option.

Addressing the root causes of energy poverty
Preventing shut-offs is a good first step, but the increased bill charges will nevertheless place greater economic pressure on an incalculable number of families. Addressing the root of the problem (energy affordability) must be prioritized when we begin to recover from the health and economic ramifications of the COVID-19 pandemic.

One way policymakers can do that is to forgive outstanding balances on utility bills, perhaps with an eligibility cap based on income. Additional funds could be made available to those who are still struggling to pay their bills via capping bills, waiving late payment fees, automating payment plans or other protective measures that rightfully place consumers (particularly vulnerable consumers) at the center of any energy-related COVID-19 response. Low-and-moderate-income energy efficiency and solar programs should be funded as much as practically possible.

New infrastructure, particularly new construction that is slated for public housing, subsidized housing, or housing specifically marketed for low- and moderate-income families, should include smart thermostats, better insulation, and energy-efficient appliances.

Implementing these solutions may seem daunting, let us not forget that one of the best ways to ease people’s energy burden is to keep a utility’s overall energy costs low. That means state utility commissions must be vigilant in utility rate cases and fuel recovery cost dockets to protect people facing unfathomable economic pressures. Unscrupulous utilities have been known to hide unnecessary costs in our energy bills. Commissions and their staff are overwhelmed at this time, but they should be applying extra scrutiny during proceedings when utilities are recovering costs associated with delivering energy.

What might a utility try to get past the commission?
Well, residential demand is up, so for many people, bills will increase. However, wholesale electricity rates are low right now, in some cases at all-time lows. Why? Because industrial and commercial demand reductions (from social distancing at home) have more than offset residential demand increases. Overall US electricity demand is flat or declining, and supply/demand economics predicts that when demand decreases, prices decrease.

At the same time, natural gas prices have set record lows each month of this year and that’s a trend that is expected to hold true for a while.

Low demand plus low gas prices mean wholesale market prices are incredibly low. Utilities should be taking advantage of low market prices to ensure that they deliver electricity to customers at as low a cost as possible. Utilities must also NOT over-run coal plants uneconomically or lean on aging capacity despite disruptions in coal and nuclear that can invite brownouts because that will not only needlessly cost customers more, but it will also increase air pollution which will exacerbate respiratory issues and susceptibility to COVID-19, according to a recent study published by Harvard.

Imported coal volumes up 17% during Apr-Oct as domestic supplies shrink

India Thermal Power Coal Imports surged 17.6% as CEA-monitored plants offset weaker CIL and SCCL supplies, driven by Saubhagya-led electricity demand, regional power deficits, and varied consumption across Uttar Pradesh, Bihar, Maharashtra, and Gujarat.

 

Key Points

Fuel volumes imported for Indian thermal plants, tracked by CEA, reflecting shifts in CIL/SCCL supply, demand, and regional power deficits.

✅ Imports up 17.6% as domestic CIL/SCCL deliveries lag targets

✅ Saubhagya-driven demand lifts generation in key beneficiary states

✅ Industrial slowdowns cut usage in Maharashtra, Tamil Nadu, Gujarat

 

The receipt of imported coal by thermal power plants, where plant load factors have risen, has shot up by 17.6 per cent during April-October. The coal import volumes refer to the power plants monitored by the Central Electricity Authority (CEA), and come amid moves to ration coal supplies as electricity demand surges, a power update report from CARE Ratings showed.

Imports escalated as domestic supplies by Coal India Ltd (CIL) and another state run producer- Singareni Collieries Company Ltd (SCCL) dipped in the period, after earlier shortages that have since eased in later months. Rate of supplies by the two coal companies to the CEA monitored power stations stood at 80.4 per cent, indicating a shortfall of 19.6 per cent against the allocated quantity.

According to the study by CARE Ratings, total coal supplied by CIL and SCCL to the power sector stood at 315.9 million tonnes (mt) during April-October as against 328.5 mt in the comparable period of last fiscal year.

The study noted that growth in power generation during the April-October 2019, with India now the third-largest electricity producer globally, was on account of higher demand from Pradhan Mantri Sahaj Bijli Har Ghar Yojana or Saubhagya Scheme beneficiary states. Providing connection to households in order to achieve 100% per cent electrification has in part helped the sector avert de-growth, as part of efforts to rewire Indian electricity and expand access.

Large states namely Uttar Pradesh, Bihar, Punjab, West Bengal and Rajasthan have recorded over five per cent growth in consumption of power. These states along with Odisha, Madhya Pradesh and Assam accounted for 75 per cent of the beneficiaries under the Saubhagya Scheme (Household Electrification Scheme). The ongoing economic downturn has led to a sharp fall in electricity demand from industrialised states. Maharashtra, which is also the largest power consuming state in India, recorded a decline in consumption of 5.6 per cent.

Other states namely Tamil Nadu, Telangana, Gujarat and Odisha too recorded fall in power consumed, echoing global dips in daily electricity demand seen later during the pandemic. These states house large clusters of mining, automobile, cement and other manufacturing industries, and a decline in these sectors led to fall in demand for power across these states. - The demand-supply gap or power deficit has remained at 0.6 per cent during the April-October 2019. North-East reported 4.8 per cent of power deficit followed by Northern Region at 1.3 per cent. Within Northern Region, Jammu & Kashmir and Uttar Pradesh accounted for 65 per cent and 30 per cent respectively of the regions power supply deficit.

Canada's nationwide climate success — electricity

Canada Clean Electricity leads decarbonization, slashing power-sector emissions through coal phase-out, renewables like hydro, wind, and solar, and nuclear. Provinces cut carbon intensity, enabling electrification of transport and buildings toward net-zero goals.

 

Key Points

Canada Clean Electricity is the shift to low-emission power by phasing out coal and scaling renewables and nuclear.

✅ 38% cut in electricity emissions since 2005; 84% fossil-free power.

✅ Provinces lead coal phase-out; carbon intensity plummets.

✅ Enables EVs, heat pumps, and building electrification.

 

It's our country’s one big climate success so far.

"All across Canada, electricity generation has been getting much cleaner. It's our country’s one big climate success so far,"

To illustrate how quickly electric power is being cleaned up, what's still left to do, and the benefits it brings, I've dug into Canada's latest emissions inventory and created a series of charts below.

 

The sector that could

Climate pollution by Canadian economic sector, 2005 to 2017My first chart shows how Canada's economic sectors have changed their climate pollution since 2005.

While most sectors have increased their pollution or made little progress in the climate fight, our electricity sector has shined.

As the green line shows, Canadians have eliminated an impressive 38 per cent of the climate pollution from electricity generation in just over a decade.

To put these shifts into context, I've shown Canada's 2020 climate target on the chart as a gray star. This target was set by the Harper government as part of the global Copenhagen Accord. Specifically, Canada pledged to cut our climate pollution 17 per cent below 2005 levels under evolving Canadian climate policy frameworks of the time.

As you can see, the electricity sector is the only one to have done that so far. And it didn’t just hit the target — it cut more than twice as much.

Change in Canada's electricity generation, 2005 to 2017My next chart shows how the electricity mix changed. The big climate pollution cuts came primarily from reductions in coal burning, highlighting the broader implications of decarbonizing Canada's electricity grid for fuel choices.

The decline in coal-fired power was replaced (and then some) by increases in renewable electricity and other zero-emissions sources — hydro, wind, solar and nuclear.

As a result, Canada's overall electricity generation is now 84 per cent fossil free.

 

Every province making progress

A primary reason why electricity emissions fell so quickly is because every province worked to clean up Canada's electricity together.

Change in Canadian provincial electricity carbon intensity, 2005 to 2017

My next chart illustrates this rare example of Canada-wide climate progress. It shows how quickly the carbon-intensity of electricity generation has declined in different provinces.

(Note: carbon-intensity is the amount of climate pollution emitted per kilowatt-hour of electricity generated: gCO2e/kWh).

Ontario clearly led the way with an amazing 92 per cent reduction in climate pollution per kWh in just twelve years. Most of that came from ending the burning of coal in their power plants. But a big chunk also came from cutting in half the amount of natural gas they burn for electricity.

Manitoba, Quebec and B.C. also made huge improvements.

Even Alberta and Saskatchewan, which were otherwise busy increasing their overall climate pollution, made progress in cleaning up their electricity.

These real-world examples show that rapid and substantial climate progress can happen in Canada when a broad-spectrum of political parties and provinces decide to act.

Most Canadians now have superclean electricity

As a result of this rapid cleanup, most Canadians now have access to superclean energy.

Canadian provincial electricity carbon intensity in 2017

 

Who has it? And how clean is it?

The biggest climate story here is the superclean electricity generated by the four provinces shown on the left side — Quebec, Manitoba, B.C. and Ontario. Eighty per cent of Canadians live in these provinces and have access to this climate-safe energy source.

Those living in Alberta and Saskatchewan, however, still have fairly dirty electricity — as shown in orange on the right — and options like bridging the electricity gap between Alberta and B.C. could accelerate progress in the West.

A lot more cleanup must happen here before the families and businesses in these provinces have a climate-safe energy supply.

 

What's left to do?

Canada's electricity sector has two big climate tasks remaining: finishing the cleanup of existing power and generating even more clean energy to replace fossil fuels like the gasoline and natural gas used by vehicles, factories and other buildings.

 

Finishing the clean up

Climate pollution from Canadian provincial electricity 2005 and 2017

As we saw above, more than a third of the climate pollution from electricity has already been eliminated. That leaves nearly two-thirds still to clean up.

Back in 2005, Canada's total electricity emissions were 125 million tonnes (MtCO2).

Over the next twelve years, emissions fell by more than a third (-46 MtCO2). Ontario did most of the work by cutting 33 MtCO2. Alberta, New Brunswick and Nova Scotia made the next biggest cuts of around 4 MtCO2 each.

Now nearly eighty million tonnes of climate pollution remain.

As you can see, nearly all of that now comes from Alberta and Saskatchewan. As a result, continuing Canada's climate progress in the power sector now requires big cuts in the electricity emissions from these two provinces.

 

Generating more clean electricity

The second big climate task remaining for Canada's electricity is to generate more clean electricity to replace the fossil fuels burned in other sectors. My next chart lets you see how big a task this is.

 

Clean electricity generation by Canadian province, 2017

It shows how much climate-safe electricity is currently generated in major provinces. This includes zero-emissions renewables (blue bars) and nuclear power (pale blue).

Quebec tops the list with 191 terawatt-hours (TWh) per year. While impressive, it only accounts for around half of the energy Quebecers use. The other half still comes from climate-damaging fossil fuels and to replace those, Quebec will need to build out more clean energy.

The good news here is that electricity is more efficient for most tasks, so fossil fuels can be replaced with significantly less electric energy. In addition, other efficiency and reduction measures can further reduce the amount of new electricity needed.

Newfoundland and Labrador is in the best situation. They are the only province that already generates more climate-safe electricity than they would need to replace all the fossil fuels they burn. They currently export most of that clean electricity.

At the other extreme are Alberta and Saskatchewan. These provinces currently produce very little climate-safe energy. For example, Alberta's 7 TWh of climate-safe electricity is only enough to cover 1 per cent of the energy used in the province.

All told, Canadians currently burn fossil fuels for three-quarters of the energy we use. To preserve a safe-and-sane climate, most provinces will soon need lots more clean electricity in the race to net-zero to replace the fossil fuels we burn.

How soon will they need it?

According to the most recent report from the International Panel on Climate Change (IPCC), avoiding a full-blown climate crisis will require humanity to cut emissions by 45 per cent over the next decade.

 

Using electricity to clean up other sectors

Finally, let's look at how electricity can help clean up two of Canada’s other high-emission sectors — transportation and buildings.

 

Cleaning up transportation

Transportation is now the second biggest climate polluting sector in Canada (after the oil and gas industry). So, it’s a top priority to reduce the amount of gasoline we use.

Canadian provincial electricity carbon intensity in 2017, plus gasoline equivalent

Switching to electric vehicles (EVs) can reduce transportation emissions by a little, or a lot. It depends on how clean the electricity supply is.

To make it easy to compare gasoline to each province's electricity I've added a new grey-striped zone at the top of the carbon-intensity chart.

This new zone shows that burning gasoline in cars and trucks has a carbon-intensity equivalent to more than 1,000 gCO2e/kWh. (If you are interested in the details of this and other data points, see the geeky endnotes.)

The good news is that every province's electricity is now much cleaner than gasoline as a transportation fuel.

In fact, most Canadians have electricity that is at least 95 per cent less climate polluting than gasoline. Electrifying vehicles in these provinces virtually eliminates those transportation emissions.

Even in Alberta, which has the dirtiest electricity, it is 20 per cent cleaner than gasoline. That's a help, for sure. But it also means that Albertans must electrify many more vehicles to achieve the same emissions reductions as regions with cleaner electricity.

In addition to reducing climate pollution, switching transportation to electricity brings other big benefits:

It reduces air pollution in cities — a major health hazard.

It cuts the energy required for transportation by 75 per cent — because electric motors are so much more efficient.

It reduces fuel costs up to 80 per cent — saving tens of thousands of dollars.

And for gasoline-importing provinces, using local electricity keeps billions of fuel dollars inside their provincial economy.

As an extra bonus, it makes it hard for companies to manipulate the price or for outsiders to "turn off the taps.”

 

Cleaning up buildings

Canada's third biggest source of climate pollution is the buildings sector.

Burning natural gas for heating is the primary cause. So, reducing the amount of fossil gas burned in buildings is another top climate requirement.

Canadian provincial electricity carbon intensity in 2017, plus gasoline and nat gas heating equivalent

Heating with electricity is a common alternative. However, it's not always less climate polluting. It depends on how clean the electricity is.

To compare these two heating sources, look at the lower grey-striped zone I've added to the chart.

It shows that heating with natural gas has a carbon-intensity of 200 to 300 gCO2 per kWh of heat delivered. High-efficiency gas furnaces are at the lower end of this range.

As you can see, for most Canadians, electric heat is now the much cleaner choice — nearly eliminating emissions from buildings. But in Alberta and Saskatchewan, electricity is still too dirty to replace natural gas heat.

The climate benefits of electric heat can be improved further by using the newer high-efficiency air-source heat pump technologies like mini-splits. These can heat using one half to one third of the electricity of standard electric baseboard heaters. That means it is possible to use electricity that is a bit dirtier than natural gas and still deliver cleaner heating. As a bonus, heat pumps can free up a lot of existing electricity supply when used to replace existing electric baseboards.

 

Electrify everything

You’ve probably heard people say that to fight climate breakdown, we need to “electrify everything.” Of course, the electricity itself needs to be clean and what we’ve seen is that Canada is making important progress on that front. The electricity industry, and the politicians that prodded them, all deserve kudos for slashing emissions at more than twice the rate of any other sector.

We still need to finish the cleanup job, but we also need to turn our sights to the even bigger task ahead: requiring that everything fossil fuelled — every building, every factory, every vehicle — switches to clean Canadian power.

Energy-insecure households in the U.S. pay 27% more for electricity than others

Community Solar for Low-Income Homes expands energy equity by delivering renewable energy access, predictable bill savings, and tax credit benefits to renters and energy-insecure households, accelerating distributed generation and storage adoption nationwide.

 

Key Points

A program model enabling renters and LMI households to subscribe to off-site solar and save on utility bills.

✅ Earn bill credits from shared solar generation.

✅ Expands access for renters and LMI subscribers.

✅ Often paired with storage and IRA tax credit adders.

 

On a square-foot basis, the issue of inequality is made worse by higher costs for energy usage in the nation. Efforts like community solar programs such as Maryland community solar are underway to boost low-income participation in the cost benefits of renewable energy.

The Energy Information Administration (EIA) shows that households that are considered energy insecure, or those that have the inability to adequately meet basic household energy costs, are paying more for electricity than their wealthier counterparts. 

On average in the United States in 2020, households were billed about $1.04 per square foot for all energy sources. For homes that did not report energy insecurity, that average was $0.98 per square foot, while homes with energy insecurity issues paid an average of $1.24 per square foot for energy. This means that U.S. residents that need the most support on their energy bills are stuck with costs 27% higher than their neighbors on square-foot-basis.

EIA said energy-insecure households have reduced or forgone basic necessities to pay energy bills, kept their houses at unsafe temperatures because of energy cost concerns, or been unable to repair heating or cooling equipment because of cost.

In 2020, households with income less than $10,000 a year were billed an average of $1.31 per square foot for energy, while households making $100,000 or more were billed an average of $0.96 per square foot, said EIA. Renters paid considerably more ($1.28 per square foot) than owners ($0.98 per square foot). There were also considerable differences between regions, with New England solar growth sparking grid upgrade debates, ethnic groups and races, and insulation levels, as seen below.

The energy transition toward renewables like solar has offered price stability, amid record solar and storage growth nationwide, but thus far energy-insecure communities have relatively been left behind. A recent Berkeley Lab report, Residential Solar-Adopter Income and Demographic Trends, indicates that even though the rate of solar adoption among low-income residents is increasing (from 5% in 2010 to 11% in 2021), that segment of energy consumers remains under-represented among solar adopters, relative to its share of the population.


Community solar efforts

As such, the United States is targeting communities most impacted by energy costs that have not benefitted from the transition, highlighting “Energy Communities” that are eligible for an additional 10% tax credit through funds made possible by the Inflation Reduction Act.

Additionally, a push for community solar development is taking place nationwide to extend access to affordable solar energy to renters and other residents that aren’t able to leverage finances to invest in predictable, low-cost residential solar systems. The Biden Administration set a goal this year to sign up 5 million community solar households, achieving $1 billion in bill savings by 2025. The community solar model only represents about 8% of the total distributed solar capacity in the nation. This target would entail a jump from 3 GW installed capacity to 20 GW by the target year. The Department of Energy estimates community solar subscribers save an average of 20% on their bills.

California this year passed AB 2316, the Community Renewable Energy Act takes aim at four acute problems in the state’s power market: reliability amid rising outage risks, rates, climate and equity. The law creates a community renewable energy program, including community solar-plus-storage, supported by cheaper batteries, to overcome access barriers for nearly half of Californians who rent or have low incomes. Community solar typically involves customers subscribing to an off-site solar facility, receiving a utility bill credit for the power it generates.

“Community renewable energy is a proven powerful tool to help close California’s clean energy gap, bringing much needed relief to millions struggling with high housing costs and utility debt,” said Alexis Sutterman, energy equity program manager at the California Environmental Justice Alliance.

The program has energy equity baked into its structure, working to make sure Californians of all income levels participate in the benefits of the energy transition. Not only does it open solar access to renters, the law ensures that at least 51% of subscribers are low-income customers, which is expected to make projects eligible for a 10% tax credit adder under the IRA.

“The money’s on the table now,” said Jeff Cramer, president and chief executive of the Coalition for Community Solar Access. “While there are groups pushing for solar access for all, and states with strong legislation, there are other pockets of interest in surprising places in the United States. For example, Louisiana has no policy for community solar or support for low-income residents going solar but the city of New Orleans has its own utility commission with a community solar program. In Nebraska, forward-looking co-operatives have created community solar projects.

Community solar markets are active in 22 states, with more expected to come online in the future as states pursue 100% clean energy targets across the country. However, the market is expected to require strong community outreach efforts to foster trust and gain subscribers.

“There is a distrust of community solar initially in LMI communities as many have been burned before by retail energy false promises,” said Eric LaMora, executive director, community solar, Nautilus Solar on a panel at the Solar Energy Industries Association Finance, Tax, and Buyers seminar. “People are suspicious but there really are no hooks with community solar.”

LMI residents are leery to provide tax records or much documents at all in order to sign up for community solar, LaMora said. “We were surprised to see less of a default rate with LMI residents. We attribute this to the fact that they see significant savings on their electric bill, making it easier to pay each month,” he said.
