US Renewable Energy Transition is the shift from fossil fuels to wind, solar, and nuclear, targeting net-zero emissions via grid modernization, battery storage, and new transmission to replace legacy plants and meet rising electrification.

 

Key Points

The move to decarbonize electricity by scaling wind, solar, and nuclear with storage and transmission upgrades.

✅ Falling LCOE makes wind and solar competitive with gas and coal.

✅ 4-hour lithium-ion storage shifts solar to evening peak demand.

✅ New high-voltage transmission links resource-rich regions to load.

 

Generating electricity to power homes and businesses is a significant contributor to climate change. In the United States, one quarter of greenhouse gas emissions come from electricity production, according to the Environmental Protection Agency.

Solar panels and wind farms can generate electricity without releasing any greenhouse gas emissions, and recent research suggests wind and solar could meet about 80% of U.S. demand with supportive infrastructure. Nuclear power plants can too, although today’s plants generate long-lasting radioactive waste, which has no permanent storage repository.

But the U.S. electrical sector is still dependent on fossil fuels. In 2021, 61 percent of electricity generation came from burning coal, natural gas, or petroleum. Only 20 percent of the electricity in the U.S. came from renewables, mostly wind energy, hydropower and solar energy, according to the U.S. Energy Information Administration, and in 2022 renewable electricity surpassed coal nationwide as portfolios shifted. Another 19 percent came from nuclear power.

The contribution from renewables has been increasing steadily since the 1990s, and the rate of increase has accelerated, with renewables projected to reach one-fourth of U.S. generation in the near term. For example, wind power provided only 2.8 billion kilowatt-hours of electricity in 1990, doubling to 5.6 billion in 2000. But from there, it skyrocketed, growing to 94.6 billion in 2010 and 379.8 billion in 2021.

That’s progress, as the U.S. moves toward 30% electricity from wind and solar this decade, but it’s not happening fast enough to eliminate the worst effects of climate change for our descendants.

“We need to eliminate global emissions of greenhouse gases by 2050,” philanthropist and technologist Bill Gates wrote in his 2023 annual letter. “Extreme weather is already causing more suffering, and if we don’t get to net-zero emissions, our grandchildren will grow up in a world that is dramatically worse off.”

And the problem is actually bigger than it looks, even as pathways to zero-emissions electricity by 2035 are being developed.

“We need not just to create as much electricity as we have now, but three times as much,” says Saul Griffith, an entrepreneur who’s sold companies to Google and Autodesk and has written books on mass electrification. To get to zero emissions, all the cars and heating systems and stoves will have to be powered with electricity, said Griffith. Electricity is not necessarily clean, but at least it it can be, unlike gas-powered stoves or gasoline-powered cars.

The technology to generate electricity with wind and solar has existed for decades. So why isn’t the electric grid already 100% powered by renewables? And what will it take to get there?

First of all, renewables have only recently become cost-competitive with fossil fuels for generating electricity. Even then, prices depend on the location, Paul Denholm of the National Renewable Energy Laboratory told CNBC.

In California and Arizona, where there is a lot of sun, solar energy is often the cheapest option, whereas in places like Maine, solar is just on the edge of being the cheapest energy source, Denholm said. In places with lots of wind like North Dakota, wind power is cost-competitive with fossil fuels, but in the Southeast, it’s still a close call.

Then there’s the cost of transitioning the current power generation infrastructure, which was built around burning fossil fuels, and policymakers are weighing ways to meet U.S. decarbonization goals as they plan grid investments.

“You’ve got an existing power plant, it’s paid off. Now you need renewables to be cheaper than running that plant to actually retire an old plant,” Denholm explained. “You need new renewables to be cheaper just in the variable costs, or the operating cost of that power plant.”

There are some places where that is true, but it’s not universally so.

“Primarily, it just takes a long time to turn over the capital stock of a multitrillion-dollar industry,” Denholm said. “We just have a huge amount of legacy equipment out there. And it just takes awhile for that all to be turned over.”

 

Intermittency and transmission
One of the biggest barriers to a 100% renewable grid is the intermittency of many renewable power sources, the dirty secret of clean energy that planners must manage. The wind doesn’t always blow and the sun doesn’t always shine — and the windiest and sunniest places are not close to all the country’s major population centers.

Wind resources in the United States, according to the the National Renewable Energy Laboratory, a national laboratory of the U.S. Department of Energy.

The solution is a combination of batteries to store excess power for times when generation is low, and transmission lines to take the power where it is needed.

Long-duration batteries are under development, but Denholm said a lot of progress can be made simply with utility-scale batteries that store energy for a few hours.

“One of the biggest problems right now is shifting a little bit of solar energy, for instance, from say, 11 a.m. and noon to the peak demand at 6 p.m. or 7 p.m. So you really only need a few hours of batteries,” Denholm told CNBC. “You can actually meet that with conventional lithium ion batteries. This is very close to the type of batteries that are being put in cars today. You can go really far with that.”

So far, battery usage has been low because wind and solar are primarily used to buffer the grid when energy sources are low, rather than as a primary source. For the first 20% to 40% of the electricity in a region to come from wind and solar, battery storage is not needed, Denholm said. When renewable penetration starts reaching closer to 50%, then battery storage becomes necessary. And building and deploying all those batteries will take time and money.

UK to fast-track vital grid connections

UK Grid Connection Fast-Track would let the Energy Secretary instruct network operators and National Grid ESO to accelerate substation upgrades and transmission links for Tata's gigafactory, electric arc furnaces, and ready-to-build renewable projects.

 

Key Points

A UK plan letting the energy secretary fast-track grid connections via priority substation and transmission upgrades.

✅ Prioritizes substations and lines for strategic projects

✅ Supports Tata gigafactory and electric arc furnace conversions

✅ Complements Ofgem queue reforms and National Grid ESO changes

 

The UK energy secretary could be handed powers to fast-track connecting electricity-hungry projects, such as Jaguar Land Rover’s owner Tata’s planned electric battery factory, to the grid, under plans being discussed between government and regulators as part of the government’s green industrial revolution strategy.

Amid concerns about supply delays of up to 15 years in hooking up large schemes, the Guardian understands the move would allow Claire Coutinho to request that energy network companies accelerate upgrades to substations and power lines to connect specific new developments.

It is understood that the government and the regulator Ofgem have told National Grid’s electricity systems operator that they are “minded” to adopt its grid reform proposals to change the model for connections, which now moves at a pace set by each network operator.

A source said: “Foreign investors need assurances that, if these things are going to be built, then they can be hooked up quickly. There are physical assets, like substations and cross-Channel cables that transmission companies will need to build or upgrade.”

The government is belatedly attempting to tackle a logjam that has resulted in some developments facing a 10- to 15-year wait for a connection to the grid. Ofgem announced on Monday plans to remove “zombie” projects from the queue to connect up to speed up those ready to produce renewable power for the grid, with wind leading the power mix.

Although no equivalent queue exists for those looking to take power from the grid, ministers and officials are concerned that large projects could struggle to secure final investment and proceed without guarantees over their connection to the electricity supply.

Sources said changes to the rules had been proposed with several big projects in mind: Tata’s new £4bn electric battery factory, expected to be built in Somerset; and the switch to electric arc furnaces at Britain’s biggest steelworks at Port Talbot in south Wales, also owned by the Indian group.

The £1.25bn plan from British Steel, which is owned by China’s Jingye, to replace two blast furnaces at Scunthorpe steelworks, with an electric arc furnace at the north Lincolnshire plant and another at a site in Teesside, North Yorkshire, has also formed part of the proposals. Negotiations over the closure of blast furnaces at Port Talbot and Scunthorpe are expected to lead to thousands of job losses.

All three projects are likely to involve significant investment from the UK government, where a state-owned generation firm has been touted as a cost-saving option, alongside the companies’ overseas owners.

Britain has 10 distribution network operators, including National Grid and Northern Powergrid, which operate monopolies in their regions and handle transmission of power from the grid to end users.

Sources said the move could be announced as soon as this month, and may be included within the “connections action plan”, a broader overhaul of Britain’s network connections.

The plan, which is expected to be announced alongside the chancellor’s autumn statement next week, will rebalance the planning system to help speed up the connection of new solar and windfarms to the grid, as the biggest offshore windfarm begins UK supply this week.

3 ways to tap billions in new money to go green - starting this month

Inflation Reduction Act Energy Credits help households electrify with tax credits and rebates for heat pumps, EVs, rooftop solar, battery storage, and efficiency upgrades, cutting utility bills, reducing carbon emissions, and accelerating home electrification nationwide.

 

Key Points

Federal incentives offering tax credits and rebates for heat pumps, EVs, solar, and efficiency to cut emissions.

✅ 30% rooftop solar and storage credit; $2,000 annual cap for heat pumps

✅ Up to $7,500 EV tax credit; price, income, and assembly rules apply

✅ Low-income rebates and discounts available via states starting mid-2023

 

Earlier this year, Congress passed the biggest climate bill in history — cloaked under the name the “Inflation Reduction Act,” a historic climate deal by any measure.

Starting in the new year, the bill will offer households thousands of dollars to transition over from fossil-fuel burning heaters, stoves and cars to cleaner versions as renewable electricity accelerates. On Jan. 1, middle-income households will be able to access over a half-dozen tax credits for electric stoves, cars, rooftop solar and more. And starting sometime in mid-2023, lower-income households will be able to get upfront discounts on some of those same appliances — without having to wait to file their taxes to get the cash back. This handy online tool shows what you might be eligible for, depending on your Zip code and income.

But which credits should Americans focus on — and which are best for the climate? Here’s a guide to the top climate-friendly benefits of the Inflation Reduction Act, and how to access them.


Heat pumps — the best choice for decarbonizing at home

Tax credit available on Jan. 1: 30 percent of the cost, up to $2,000

Income limit: None

Ah, heat pumps — one of the most popular technologies of the transition to clean energy and to net-zero electricity systems. “Heat pump” is a bit of a misnomer for these machines, which are more like super-efficient combo air conditioning and heating systems. These appliances run on electricity and move heat, instead of creating it, and so can be three to five times more efficient than traditional gas or electrical resistance heaters.

“For a lot of people, a heat pump is going to be their biggest personal impact,” said Sage Briscoe, the federal senior policy manager at Rewiring America, a clean-energy think tank. (Heat pumps have become so iconic that Rewiring America even has a heat pump mascot.)

Heat pumps can have enormous cost and carbon savings. According to one analysis using data from the National Renewable Energy Laboratory, switching to a heat pump can save homeowners anywhere from $100 to $1,200 per year on heating bills and prevent anywhere from 1 to 8 metric tons of carbon dioxide emissions per year. For comparison, going vegan for an entire year saves about 1 metric ton of CO2 emissions.

But many consumers encounter obstacles when switching over to heat pumps. In some areas, it can be difficult to find a contractor trained and willing to install them; some homeowners report that contractors share misinformation about heat pumps, including that they don’t work in cold climates. (Modern heat pumps do work in cold climates, and can heat a home even when outdoor temperatures are down to minus-31 degrees Fahrenheit.) Briscoe recommends that homeowners look for skilled contractors who know about heat pumps and do advance research to figure out which models might work best for their home.


Electric vehicles — top choice for cutting car emissions

Tax credit available on Jan. 1: Up to $7,500 depending on the make and model of the car

Income limit: <$150,000 for single filers; <$300,000 for joint filers

If you are like the millions of Americans who don’t live in a community with ample public transit, the best way to decarbonize your transport, as New Zealand's electricity transition shows, is switching to an electric car. But electric cars can be prohibitively expensive for many Americans.

Starting Jan. 1, a new EV tax credit will offer consumers up to $7,500 off the purchase of an electric vehicle. For the first few months, Americans will get somewhere between $3,751 and $7,500 off their purchase of an EV, depending on the size of the battery in the car.

There are limitations, per the new law. The vehicles will also have to be assembled in North America, where Canada's electricity progress is notable, and cars that cost more than $55,000 aren’t eligible, nor are vans or trucks that cost more than $80,000. This week, the Internal Revenue Service provided a list of vehicles that are expected to meet the criteria starting Jan. 1.

Beginning about March, however, that $7,500 credit will be split into two parts: Consumers can get a $3,750 credit if the vehicle has a battery containing at least 40 percent critical minerals from the United States (or a country that the United States has a free-trade agreement with) and another $3,750 credit if at least 50 percent of the battery’s components were assembled and manufactured in North America. Those rules haven’t been finalized yet, so the tax credit starting on Jan. 1 is a stopgap measure until the White House has ironed out the final version.

Joe Britton, the executive director of the EV industry group Zeta, said that means there will likely be a wider group of vehicles eligible for the full tax credit in January and February than there will be later in 2023. Because of this, he recommended that potential EV owners act fast in 2023.

“I would be buying a car in the first quarter,” he said.


Rooftop solar — the best choice for generating clean energy

Tax credit available now: 30 percent of the cost of installation, no cap

Income limit: None

For those who want to generate their own clean energy, there is always rooftop solar panels. This tax credit has actually been available since the Inflation Reduction Act was signed into law in August 2022. It offers a tax credit equal to 30 percent of the cost of installing rooftop solar, with no cap. According to Rewiring America, the average 6 kilowatt solar installation costs about $19,000, making the average solar tax credit about $5,700. (The Inflation Reduction Act also includes a 30 percent tax credit for homeowners that need to upgrade their electricity panel for rooftop solar, and a 30 percent tax credit for installing battery storage to support the shift toward carbon-free electricity solutions.)

Solar panels can save homeowners tens of thousands of dollars in utility bills as extreme heat boosts electricity bills and, when combined with battery storage, can also provide a power backup in the case of a blackout or other disaster. For someone trying to move their entire home away from fossil fuels, solar panels become even more enticing: Switch everything over to electricity, and then make the electricity super cheap with the help from the sun.

For people who don’t own their own homes, there are other options as well. Renters can subscribe to a community solar project to lower their electricity bills and get indirect benefits from the tax credits.


Tips, tricks and words of caution
There are many other credits also coming out in 2023: for EV chargers (up to $1,000), a boon for expanding carbon-free electricity across the grid, heat pump water heaters (up to $2,000), and even cash for sealing up the doors and windows of your home (up to $1,200).

The most important thing to know, Briscoe said, is whether you qualify for the upfront discounts for low- and moderate-income Americans — which won’t be available until later in 2023 — or the tax credits, which will be available Jan. 1. (Try this tool.) If going the tax credit route, it’s better to spread the upgrades out across multiple years, since there is an annual limit on how many of the credits you can claim in a given year. And, she warned, it is not always going to be easy: It can be hard to find the right installers and the right information for how to make use of all the available government resources.

Peer-to-peer energy breakthrough could allow solar and wind energy sources to be shared

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

 

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

 

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

 

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

 

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

Biden's proposed tenfold increase in solar power would remake the U.S. electricity system

US Solar Power 2050 Target projects 45% electricity from solar, advancing decarbonization with clean energy, wind, nuclear, hydropower, hydrogen, and scalable energy storage, while modernizing the grid and transmission to cut emissions and create jobs.

 

Key Points

A goal for solar to supply ~45% of US electricity by 2050, backed by energy storage and other low-carbon generation.

✅ Requires 1,050-1,570 GW solar and matching storage capacity

✅ Utility-scale buildout uses ~10M acres; rooftop 10-20% of capacity

✅ Complemented by wind, nuclear, hydropower, hydrogen, and flexible turbines

 

President Joe Biden has called for major clean energy investments as a way to curb climate change and generate jobs. On Sept. 8, 2021, the White House released a report produced by the U.S. Department of Energy that found that solar power could generate up to 45% of the U.S. electricity supply by 2050, compared to less than 4% today, with about 3% in 2020 noted by industry observers. The Conversation asked Joshua D. Rhodes, an energy technology and policy researcher at the University of Texas at Austin, what it would take to meet this target.

Why such a heavy focus on solar power? Doesn’t a low-carbon future require many types of clean energy, even though wind and solar could meet about 80% of demand according to some research?
The Energy Department’s Solar Futures Study lays out three future pathways for the U.S. grid: business as usual; decarbonization, meaning a massive shift to low-carbon and carbon-free energy sources; and decarbonization with economy-wide electrification of activities that are powered now by fossil fuels.

It concludes that the latter two scenarios would require approximately 1,050-1,570 gigawatts of solar power, which would meet about 44%-45% of expected electricity demand in 2050, even as renewables approach one-fourth of U.S. generation in the near term. For perspective, one gigawatt of generating capacity is equivalent to about 3.1 million solar panels or 364 large-scale wind turbines.

The rest would come mostly from a mix of other low- or zero-carbon sources, including wind, nuclear, hydropower, biopower, geothermal and combustion turbines run on zero-carbon synthetic fuels such as hydrogen. Energy storage capacity – systems such as large installations of high-capacity batteries – would also expand at roughly the same rate as solar, with record growth in solar and storage anticipated by industry in coming years.

One advantage solar power has over many other low-carbon technologies is that most of the U.S. has lots of sunshine. Wind, hydropower and geothermal resources aren’t so evenly distributed: There are large zones where these resources are poor or nonexistent.

Relying more heavily on region-specific technologies would mean developing them extremely densely where they are most abundant. It also would require building more high-voltage transmission lines to move that energy over long distances, which could increase costs and draw opposition from landowners – a key reason the grid isn't yet 100% renewable according to experts – in many regions.

Is generating 45% of U.S. electricity from solar power by 2050 feasible?
I think it would be technically possible but not easy. It would require an accelerated and sustained deployment far larger than what the U.S. has achieved so far, even as the cost of solar panels has fallen dramatically, and wind, solar and batteries are 82% of the utility-scale pipeline across the country. Some regions have attained this rate of growth, albeit from low starting points and usually not for long periods.

The Solar Futures Study estimates that producing 45% of the nation’s electricity from solar power by 2050 would require deploying about 1,600 gigawatts of solar generation. That’s a 1,450% increase from the 103 gigawatts that are installed in the U.S. today, even as wind and solar trend toward 30% of U.S. electricity in some outlooks. For perspective, there are currently about 1,200 gigawatts of electricity generation capacity of all types on the U.S. power grid.

The report assumes that 10%-20% of this new solar capacity would be deployed on homes and businesses. The rest would be large utility-scale deployments, mostly solar panels, plus some large-scale solar thermal systems that use mirrors to reflect the sun to a central tower.

Assuming that utility-scale solar power requires roughly 8 acres per megawatt, this expansion would require approximately 10.2 million to 11.5 million acres. That’s an area roughly as big as Massachusetts and New Jersey combined, although it’s less than 0.5% of total U.S. land mass.

I think goals like these are worth setting, but are good to reevaluate over time to make sure they represent the most prudent path.

Why a green recovery goes far deeper than wind energy

Scotland Green Recovery Strategy centers on renewable energy, onshore wind, energy efficiency, battery storage, hydrogen, and electric vehicles, alongside public transport and digital infrastructure, local manufacturing, and grid flexibility to decarbonize industry and communities.

 

Key Points

A plan to cut emissions by scaling renewables, efficiency, storage, and infrastructure for resilient, low-carbon growth.

✅ Prioritize energy efficiency retrofits in homes and workplaces

✅ Invest in battery storage, hydrogen, and EV charging networks

✅ Support local manufacturing and circular economy supply chains

 

THE “green recovery” joins the growing list of Covid-era political maxims, while green energy investment could drive recovery, suggesting a bright and environmentally sustainable post-pandemic future lies ahead.

The Prime Minister once again alluded to it recently when he expressed his ambition to see the UK become the “world leader in clean wind energy”. In his typically bombastic style, Boris Johnson declared that everything from our kettles to electric vehicles, with offshore wind energy central to that vision, will be powered by “breezes that blow around these islands” by the next decade.

These comments create a misleading impression about how we can achieve a green recovery, particularly as Covid-19 hit renewables and exposed systemic challenges. While wind turbines have a key role to play, they are just one part of a comprehensive solution requiring a far more in-depth focus on how and why we use energy. We must concentrate our efforts and resources on reducing our overall consumption and increasing energy capture.

This includes making significant energy efficiency improvements to the buildings where we live and work and grasping the lessons of lockdown, including proposals for a fossil fuel lockdown to accelerate climate action, to ensure we operate in a more effective and less environmentally-damaging fashion. Do we really want to return to a world where people commute daily half way across the country for work or fly to New York for a two-hour meeting?

Businesses will need to adapt to new ways of operating outwith the traditional nine-to-five working week to reduce congestion and pollution levels. To make this possible requires Government investment in critical areas such as public transport and digital infrastructure, alongside more pylons to strengthen the grid, across all parts of Scotland to decentralise the economy and enable more people to live and work outside the main cities.

A Government-supported green recovery must rest on making it financially viable for businesses to manufacture here to reduce our reliance on imported goods. This includes processing recycleable materials here rather than shipping them abroad. It also means using locally generated energy to support local jobs and industry. We miss a trick if Scotland simply becomes a power generator for the rest of the UK.

MOVING transport from fossil fuels to renewable fuels will require a step-change that also requires support across all levels. The increased use of electric vehicles and hydrogen fuel cells are all encouraging developments, but these will rely on investment in infrastructure throughout the country if we’re to achieve significant benefits to our environment and our economy.

This brings us to the role of onshore wind power; still the cheapest form of renewable energy, and a sector marked by wind growth despite Covid-19 around the world today. Repowering existing sites with newer and more efficient turbines will certainly increase capacity rapidly, but we must also invest into development projects that will further enhance the capacity and efficiency of existing equipment. This includes improving on the current practice of the National Grid paying operators to switch off wind turbines when excess electricity is produced and instead developing new and innovative means to capture this energy. Government-primed investment into battery storage could help ensure we achieve and further reduce our reliance on traditional, non-sustainable sources.

We need a level playing field so that all forms of energy are judged on their lifetime cost in terms of emissions as well as construction and decommissioning costs to ensure fiscal incentives are applied on a fairer basis.

Turning the maxim of a green recovery into reality will require more than extra wind turbines, and the UK's wind lessons underscore the importance of policy and scale. We need a significant investment and commitment from business and government to limit existing emissions and ensure we capture and use energy more efficiently.

Canada's race to net-zero and the role of renewable energy

Canada Net-Zero demands renewable energy deployment, leveraging hydropower to integrate wind, solar, and storage, scaling electrification, cutting oil and gas emissions, aligning policy, carbon pricing, and investment to deliver a clean grid by 2050.

 

Key Points

A national goal to cut emissions 40-45% by 2030 and reach economy-wide net-zero by 2050 through clean electrification.

✅ Hydropower balances intermittent wind and solar.

✅ Policy, carbon pricing, and investment accelerate deployment.

✅ Clean energy jobs surge as oil and gas decline.

 

As the UN climate talks draw near, Canada has enormous work left to do to reach its goals of reducing greenhouse gas emissions. Collectively, Canadians have to cut overall greenhouse-gas emissions by 40 to 45 per cent below 2005 levels by 2030 and achieve net-zero by 2050 across the economy.

And whereas countries like the U.K. have dramatically slashed their emissions levels, Canada's one of the few nations where emissions keep skyrocketing, and where fossil fuel extraction keeps increasing every year despite our climate targets.

As Trudeau seeks to cement his political legacy, these are the MPs he’s considering for cabinet
By Andrew Perez | Opinion | October 25th 2021
In the upcoming online Conversations event on Thursday, 11 a.m. PT/2 p.m. ET, host and Canada's National Observer deputy managing editor David McKie will discuss how cleaning up Canada's electricity and renewable energy can put the country on track to hitting its targets with Clean Energy Canada executive director Merran Smith, Canadian Institute for Climate Choices senior economist Dale Beugin, and WaterPower Canada CEO Anne-Raphaëlle Audouin.

Getting to net-zero grid through renewable electricity
“If we wanted to be powered by 100 per cent renewable electricity, including proposals for a fully renewable electricity grid by 2030, Canada is one of the countries where this is actually possible,” said Audouin.

She says for that to happen, it would take a slate of clean energy providers working together to fill the gaps, rather than competing for market dominance.

“You couldn't power Canada just with wind and solar, even with batteries. That being said, renewables happen to work very well together ” she said. “Hydropower already makes up more than 90 per cent of Canada’s renewable generation and 60 per cent of the country’s total electricity needs are currently met thanks to this flexible, dispatchable, abundant source of baseload renewable electricity. It isn’t a stretch of the imagination to envision hydropower and wind and solar working increasingly together to clean up our grid. In fact, hydropower already backs up and allows intermittent renewable energies like wind and solar onto the grid.”

She noted that while hydropower alone won't be the solution, its long history and indisputable suite of attributes — hydroelectricity has been in Canada since the 1890s — will make it a key part of the clean energy transition required to replace coal, natural gas and oil, which still make up around 20 per cent of Canada's power sources.

Canada's vast access to water, wind, biomass, solar, geothermal, and ocean energy, and a federal government that has committed to climate goals, makes us well-positioned to lead the way to a net-zero future and eventually the electrification of our economy. So, what's holding the country back?

The new reality for renewables
According to Clean Energy Canada, it's possible to grow the clean energy sector, but only if businesses invest massively in renewables and governments give guidance and oversight informed by the implications of decarbonizing Canada's electricity grid research.

A recent modelling study from Clean Energy Canada and Navius Research exploring the energy picture here in Canada over the next decade shows our clean energy sector is expected to grow by about 50 per cent by 2030 to around 640,000 people. Already, the clean energy industry provides 430,500 jobs — more than the entire real estate sector — and that growth is expected to accelerate as our dependence on oil and gas decreases. In fact, clean energy jobs in Alberta are predicted to jump 164 per cent over the next decade.

Currently, provinces with the most hydropower generation are also the ones with the lowest electricity rates, reflecting that electricity has been a nationwide climate success in Canada. Wind and solar are now on par, or even more competitive, than natural gas, and that could have big implications for other major sectors of the economy. Grocery giant Loblaws (which owns brands including President's Choice, Joe Fresh, and Asian grocery chain T&T) deployed its fleet of fully electric delivery trucks in recent years, and Hydro-Québec just signed a $20-billion agreement to help power and decarbonize the state of New York over the next 25 years.

In The New Reality, Smith writes that many carbon-intensive industries, such as the mining sector, could also potentially benefit from the increased demand for certain natural resources — like lithium and nickel — as the world switches to electric vehicles and clean power.

“Oil and gas may have dominated Canada’s energy past, but it’s Canada’s clean energy sector that will define its new reality,” Smith emphasized.

Despite its vast potential to be one of the world's clean energy leaders, Canada has a long way to getting on the path to net zero. Even though the country is home to some of the world's leading cleantech companies, such as B.C.-based clean hydrogen fuel cell providers Ballard Power and Loop Energy and Nova Scotia-based carbon utilization company CarbonCure, the country continues to expand fossil fuel extraction to the point that emissions are projected to jump to around 1,500 MtCO2 worth by 2030.
