US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

 

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

 

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Solar and wind power curtailments are rising in California

CAISO Renewable Curtailments reflect grid balancing under transmission congestion and oversupply, reducing solar and wind output while leveraging WEIM trading, battery storage, and transmission expansion to integrate renewables and stabilize demand-supply.

 

Key Points

CAISO renewable curtailments are reductions in wind and solar output to balance grid amid congestion or oversupply.

✅ Driven mainly by transmission congestion, less by oversupply.

✅ Peaks in spring when demand is low and solar output is high.

✅ Mitigated by WEIM trades, new lines, and battery storage growth.

 

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation, as reported in rising curtailments, as it balances supply and demand during the rapid growth of wind and solar power in California.

Grid operators must balance supply and demand to maintain a stable electric system as advances in solar and wind continue to scale. The output of wind and solar generators are reduced either through price signals or rarely, through an order to reduce output, during periods of:

Congestion, when power lines don’t have enough capacity to deliver available energy
Oversupply, when generation exceeds customer electricity demand

In CAISO, curtailment is largely a result of congestion. Congestion-related curtailments have increased significantly since 2019 because California's solar boom has been outpacing upgrades in transmission capacity.

In 2022, CAISO curtailed 2.4 million megawatthours (MWh) of utility-scale wind and solar output, a 63% increase from the amount of electricity curtailed in 2021. As of September, CAISO has curtailed more than 2.3 million MWh of wind and solar output so far this year, even as the US project pipeline is dominated by wind, solar, and batteries.

Solar accounts for almost all of the energy curtailed in CAISO—95% in 2022 and 94% in the first seven months of 2023. CAISO tends to curtail the most solar in the spring when electricity demand is relatively low (because moderate spring temperatures mean less demand for space heating or air conditioning) and solar output is relatively high, although wildfire smoke impacts can reduce available generation during fire season as well.

CAISO has increasingly curtailed renewable generation as renewable capacity has grown in California, and the state has even experienced a near-100% renewables moment on the grid in recent years. In 2014, a combined 9.0 gigawatts (GW) of wind and solar capacity had been built in California. As of July 2023, that number had grown to 17.6 GW. Developers plan to add another 3.0 GW by the end of 2024.

CAISO is exploring and implementing various solutions to its increasing curtailment of renewables, including:

The Western Energy Imbalance Market (WEIM) is a real-time market that allows participants outside of CAISO to buy and sell energy to balance demand and supply. In 2022, more than 10% of total possible curtailments were avoided by trading within the WEIM. A day ahead market is expected to be operational in Spring 2025.

CAISO is expanding transmission capacity to reduce congestion. CAISO’s 2022–23 Transmission Planning Process includes 45 transmission projects to accommodate load growth and a larger share of generation from renewable energy sources.

CAISO is promoting the development of flexible resources that can quickly respond to sudden increases and decreases in demand such as battery storage technologies that are rapidly becoming more affordable. California has 4.9 GW of battery storage, and developers plan to add another 7.6 GW by the end of 2024, according to our survey of recent and planned capacity changes. Renewable generators can charge these batteries with electricity that would otherwise have been curtailed.

World Bank helps developing countries wind spurt

World Bank Offshore Wind Investment drives renewables and clean energy in developing countries, funding floating turbines and shallow-water foundations to replace fossil fuels, expand grids, and scale climate finance across Latin America, Africa, and Asia.

 

Key Points

A World Bank program funding offshore wind to speed clean power, cut fossil fuels, and expand grids in emerging markets.

✅ US$80bn to 565 onshore wind projects since 1995

✅ Pilot funds offshore wind in Asia, Africa, Latin America

✅ Floating turbines and shallow-water foundations enable deep resources

 

Europe and the United States now accept onshore wind power as the cheapest way to generate electricity, and U.S. lessons from the U.K. are informing policy discussions. But this novel technology still needs subsidising before some developing countries will embrace it. Enter the World Bank.

A total of US$80 billion in subsidies from the Bank has gone over 25 years to 565 developing world onshore wind projects, to persuade governments to invest in renewables rather than rely on fossil fuels.

Central and Latin American countries have received the lions share of this investment, but the Asia Pacific region and Eastern Europe have also seen dozens of Bank-funded developments. Now the fastest-growing market is in Africa and the Middle East, where West African hydropower support can complement variable wind resources.

But while continuing to campaign for more onshore wind farms, the World Bank in 2019 started encouraging target countries to embrace offshore wind as well. This uses two approaches: turbines in shallow water, which are fixed to the seabed, and also a newer technology, involving floating turbines anchored by cables at greater depth.

The extraordinary potential for offshore wind, which is being commercially developed very fast in Europe, including the UK's offshore expansion, China and the U.S. offshore wind sector today as well, is now seen by the Bank as important for countries like Vietnam which could harness enough offshore wind power to provide all its electricity needs.

Other countries it has identified with enormous potential for offshore wind include Brazil, Indonesia, India, the Philippines, South Africa and Sri Lanka, all of them countries that need to keep building more power stations to connect every citizen to the national grid.

The Bank began investing in wind power in 1995, with its spending reaching billions of dollars annually in 2011. The biggest single recipient has been Brazil, receiving US$24.2 bn up to the end of 2018, 30 per cent of the total the Bank has invested worldwide.

Many private companies have partnered with the Bank to build the wind farms. The biggest single beneficiary is Enel, the Italian energy giant, which has received US$6.1 bn to complete projects in Brazil, Mexico, South Africa, Romania, Morocco, Bulgaria, Peru, and Russia.

Among the countries now benefitting from the Banks continuing onshore wind programme are Egypt, Morocco, Senegal, Jordan, Vietnam, Thailand, Indonesia and the Philippines.

Offshore wind now costs less than nuclear power, and global costs have fallen enough to compete in most countries with fossil fuels. Currently the fastest-growing industry in the world, it continued to grow despite Covid-19 across most markets.

Persistent coal demand

Particularly in Asia, some countries are continuing to burn large quantities of coal and are considering investing in yet more fossil fuel generation unless they can be persuaded that renewables are a better option, with an offshore wind $1 trillion outlook underscoring the scale.

Last year the World Bank began a pilot scheme to explore funding investment in offshore wind in these countries. Launching the scheme Riccardo Puliti, a senior director at the Bank, said: Offshore wind is a clean, reliable and secure source of energy with massive potential to transform the energy mix in countries that have great wind resources.

We have seen it work in Europe we can now make use of global experience to scale up offshore wind projects in emerging markets.

Using data from the Global Wind Atlas, the Bank calculated that developing countries with shallow waters like India, Turkey and Sri Lanka had huge potential with fixed turbines, while others the Philippines and South Africa, for example would need floating foundations to reach greater depths, up to 1,000 metres.

For countries like Vietnam, with a mix of shallow and deep water, wind power could solve their entire electricity needs. In theory offshore wind power could produce ten times the amount of electricity that the country currently gets from all its current power stations, the Bank says.

UK Electric cars will cost more if Sunak fails to strike Brexit deal

UK-EU EV Tariffs 2024 threaten a 10% levy under Brexit rules of origin, raising electric vehicle prices, straining battery supply chains, and risking a price war for manufacturers, consumers, and climate targets across automotive market.

 

Key Points

Tariffs from Brexit rules of origin imposing 10% duties on EVs, raising UK prices amid battery and supply chain gaps.

✅ 10% tariffs if rules of origin thresholds are unmet

✅ Price hikes on UK EVs, led by Tesla Model Y

✅ Battery supply gaps strain UK and EU manufacturers

 

Electric cars will cost British motorists an extra £6,000 if Rishi Sunak fails to strike a post-Brexit deal with the EU on tariffs, industry bosses have told The Independent.

UK manufacturers warned of a “devastating price war” on consumers, echoing UK concern over higher EV prices across the market – threatening both the electric vehicle (EV) market and the UK’s climate change commitments – if tariffs are enforced in January 2024.

In the latest major Brexit row, the Sunak government is pushing the European Commission to agree to delay the costly new rules, even as the UK readies for rising EV adoption across the economy, set to come in at the start of next year as part of Boris Johnson’s Brexit trade deal.

But Brussels has shown no sign it is willing to budge – even as Washington has announced a 100% tariff on Chinese-made EVs this year – leaving business leaders in despair about the impact of 10 per cent tariffs on exports on Britain’s car industry.

The tariffs would increase the price of a new Tesla Model Y – the UK’s most popular electric vehicle – by £6,000 or more, according to a new report by the Independent Commission on UK-EU Relations.

“For the sake of our economy and our planet, the government has a responsibility to get round the table with the EU, fix this and fix the raft of other issues with the Brexit deal,” said commission director Mike Buckley.

The new rules of origin agreed in the Brexit trade and cooperation agreement (TCA) require 45 per cent of an electric car’s value, as the age of electric cars accelerates, to originate in the UK or EU to qualify for trade without tariffs.

The British auto industry has warned the 2024 rules pose an “existential threat” to sales because of the lack of domestic batteries to meet the rules, even as EV adoption within the decade is widely expected to surge – pleading for a delay until 2027.

The VDA – the lobby group for Germany’s car industry – has also called for an “urgent” move to delay, warning that the rules create a “significant competitive disadvantage” for European carmarkers in relation to China, where tariffs on Chinese EVs are reshaping global trade, and other Asian competitors.

The new report by the Independent Commission on UK-EU Relations – backed by the manufacturers’ body Make UK and the British Chamber of Commerce – warns that the January tariffs will immediately push up costs and hit electric vehicle sales, despite UK EV inquiries surging during the fuel supply crisis in recent years.

Feds announce $500M contract with Edmonton company for green electricity

Canada Renewable Energy Partnerships advance wind power and clean electricity in Alberta and Saskatchewan, cutting emissions and supporting net-zero goals through Capital Power and SaskPower agreements with Indigenous participation and 25-year supply contracts.

 

Key Points

Government-backed deals with Capital Power and SaskPower to deliver clean electricity and reduce emissions.

✅ 25-year renewable supply for federal facilities

✅ New Halkirk 2 Wind project in Alberta

✅ Emissions cuts with Indigenous participation

 

The Government of Canada has partnered with two major energy providers in Western Canada (Prairie provinces) on renewable energy projects.

Tourism Minister Randy Boissonnault appeared in Edmonton on Friday to announce a new Alberta wind-generation facility in partnership with Capital Power.

It's one of two new energy partnerships in Western Canada as part of the 2030 emissions reduction plan by Public Services and Procurement Canada.

On Jan. 1, the federal government awarded a contract worth up to $500 million to Capital Power to provide all federal facilities in Alberta with renewable electricity as part of Alberta's renewable energy surge for 25 years.

"We're proud to partner with the government of Canada to help them reach their 100 per cent clean electricity by 2025 goal," said Jason Comandante, Capital Power vice president of commercial services.

The agreement also includes opportunities for Indigenous participation, including facility development partnerships and employment and training opportunities.

"At Capital Power, we are committed to net-zero by 2045, and are proud to take action against climate change. Collaborative agreements like this help support our net-zero goals, provide us opportunities to meaningfully engage Indigenous communities, and help decarbonize Alberta's power grid," Comandante said.

Capital Power will provide around 250,000 megawatt-hours of electricity each year through existing renewable energy credits while the new Capital Power Halkirk 2 Wind facility is being developed.

Located near Paintearth, Alta., the proposed wind farm will have up to 35 turbines and generate enough power for the average yearly electricity needs of more than 70,000 Alberta homes.

The project is currently awaiting regulatory approval, within Alberta's energy landscape, with construction projected to begin this summer. When complete, it will supply 49 per cent of its output to the federal government.

"Through the agreement, the federal government is supporting the ongoing development of renewable energy infrastructure development within the province," Boissonnault said.

The new partnership will join another in Saskatchewan and complement Alberta solar facilities that have been contracted at lower cost than natural gas.

In 2022, the federal government signed an agreement with SaskPower to supply clean electricity to the approximately 600 federal facilities in Saskatchewan. That wind project is expected to come online by 2024.

Boissonnault said the two initiatives combined will reduce carbon dioxide emissions in Alberta and Saskatchewan by about 166 kilotonnes.

"That is the equivalent of the emissions from more than 50,000 cars driven for one year. So, if you think about that, that's a great reduction right here in Alberta and Saskatchewan," he said.

"These are concrete steps to ensuring that Canada remains a leader of renewable energy on the global stage and grid modernization projects to help the fight against climate change."

The government's 2035 electric vehicle mandate is delusional

Canada 2035 Zero-Emission Vehicle Mandate sets EV sales targets, raising concerns over affordability, battery materials like lithium and copper, charging infrastructure, grid capacity, renewable energy mix, and policy impacts across provinces.

 

Key Points

Mandate makes all new light-duty vehicles zero-emission by 2035, affecting costs, charging, and electric grid planning.

✅ 100% ZEV sales target for cars, SUVs, light trucks by 2035

✅ Cost pressures from lithium, copper, nickel; EVs remain pricey

✅ Grid, charging build-out needed; impacts vary by provincial mix

 

Whether or not you want one, can afford one or think they will do essentially nothing to stop global warming, electric vehicles are coming to Canada en masse. This week, the Canadian government set 2035 as the “mandatory target” for the sale of zero-emission SUVs and light-duty trucks as part of ambitious EV goals announced by Ottawa.

That means the sale of gasoline and diesel cars has to stop by then. Transport Minister Omar Alghabra called the target “a must.” The previous target was 2040.

It is a highly aspirational plan that verges on the delusional according to skeptics of an EV revolution who argue its scale is overstated, even if it earns Canada – a perennial laggard on the emission-reduction front – a few points at climate conferences. Herewith, a few reasons why the plan may be unworkable, unfair or less green than advertised.

Liberals say by 2035 all new cars, light-duty trucks sold in Canada will be electric, as Ottawa develops EV sales regulations to implement the mandate.

Parkland to roll out electric-vehicle charging network in B.C. and Alberta

Sticker shock: There is a reason why EVs remain niche products in almost every market in the world (the notable exception is in wealthy Norway): They are bloody expensive and often in short supply in many markets. Unless EV prices drop dramatically in the next decade, Ottawa’s announcement will price the poor out of the car market. Transportation costs are a big issue with the unrich. The 2018 gilets jaunes mass protests in France were triggered by rising fuel costs.

While some EVs are getting cheaper, even the least expensive ones are about double the price of a comparable product with an internal combustion engine. Most EVs are luxury items. The market leader in Canada and the United States is Tesla. In Canada the cheapest Tesla, the Model 3 (“standard range plus” version), costs $49,000 before adding options and subtracting any government purchase incentives. A high-end Model S can set you back $170,000.

To be sure, prices will come down as production volumes increase. But the price decline might be slow for the simple reason that the cost of all the materials needed to make an EV – copper, cobalt, lithium, nickel among them – is climbing sharply and may keep climbing as production increases, straining supply lines.

Lithium prices have doubled since November. Copper has almost doubled in the past year. An EV contains five times more copper than a regular car. Glencore, one of the biggest mining companies, estimated that copper production needs to increase by a million tonnes a year until 2050 to meet the rising demand for EVs and wind turbines, a daunting task given the dearth of new mining projects.

Will EVs be as cheap as gas cars in a decade or so? Impossible to say, but given the recent price trends for raw materials, probably not.

Not so green: There is no such thing as a zero-emission vehicle, even if that’s the label used by governments to describe battery-powered cars. So think twice if you are buying an EV purely to paint yourself green, as research finds they are not a silver bullet for climate change.

In regions in Canada and elsewhere in the world that produce a lot of electricity from fossil-fuel plants, driving an EV merely shifts the output of greenhouse gases and pollutants from the vehicle itself to the generating plant (according to recent estimates, about 18% of Canada’s electricity comes from coal, natural gas and oil; in the United States, 60 per cent).

An EV might make sense in Quebec, where almost all the electricity comes from renewable sources and policymakers push EV dominance across the market. An EV makes little sense in Saskatchewan, where only 17 per cent comes from renewables – the rest from fossil fuels. In Alberta, only 8 per cent comes from renewables.

The EV supply chain is also energy-intensive. And speaking of the environment, recycling or disposing of millions of toxic car batteries is bound to be a grubby process.

Where’s the juice?: Since the roofs of most homes in Canada and other parts of the world are not covered in solar panels, plugging in an EV to recharge the battery means plugging into the electrical grid. What if millions of cars get plugged in at once on a hot day, when everyone is running air conditioners?

The next few decades could emerge as an epic energy battle between power-hungry air conditioners, whose demand is rising as summer temperatures rise, and EVs. The strain of millions of AC units running at once in the summer of 2020 during California’s run of record-high temperatures pushed the state into rolling blackouts. A few days ago, Alberta’s electricity system operator asked Albertans not to plug in their EVs because air conditioner use was straining the electricity supply.

According to the MIT Technology Review, rising incomes, populations and temperatures will triple the number of air conditioners used worldwide, to six billion, by mid-century. How will any warm country have enough power to recharge EVs and run air conditioners at the same time? The Canadian government didn’t say in its news release on the 2035 EV mandate. Will it fund the construction of new fleets of power stations?

The wrong government policy: The government’s announcement made it clear that widespread EV use – more cars – is central to its climate policy. Why not fewer cars and more public transportation? Cities don’t need more cars, no matter the propulsion system. They need electrified buses, subways and trains powered by renewable energy. But the idea of making cities more livable while reducing emissions is apparently an alien concept to this government.

Biden's Climate Law Is Working, and Not Working

Inflation Reduction Act Clean Energy drives EV adoption and renewable power, but grid interconnection, permitting, and supply chain bottlenecks slow wind, solar, and offshore projects, risking emissions targets despite domestic manufacturing growth and tax incentives.

 

Key Points

An IRA push to scale EVs and renewables, meeting EV goals but lagging wind and solar amid grid and permitting delays.

✅ EV sales up 50%, 9.2% of 2023 new cars; growth may moderate.

✅ 32.3 GW added, below 46-79 GW/year needed for climate targets.

✅ Grid, permitting, and supply chain delays bottleneck wind and solar.

 

A year and a half following President Biden's enactment of an ambitious climate change bill, the landscape of the United States' clean energy transition, shaped by 2021 electricity lessons, presents a mix of successes and challenges. A recent study by a consortium of research organizations highlights that while electric vehicle (EV) sales have surged, aligning with the law's projections, the expansion of renewable energy sources like wind and solar has encountered significant hurdles.

The legislation, known as the Inflation Reduction Act, aimed for a dual thrust in America's climate strategy: boosting EV adoption, alongside EPA emission limits, and significantly increasing the generation of electricity from renewable resources. The Act, passed in 2022, was anticipated to propel the United States toward reducing its greenhouse gas emissions by approximately 40 percent from 2005 levels by the end of this decade, backed by extensive financial incentives for clean energy advancements.

Electric vehicle sales have indeed seen a remarkable uptick, with a more than 50 percent increase over the past year, as EV sales surge into 2024 across the market, culminating in EVs comprising 9.2 percent of all new car sales in the United States in 2023. This growth trajectory met the upper range of analysts' predictions post-law enactment, signaling a strong start toward achieving the Act's emission reduction targets.

However, the EV market faces uncertainties regarding the sustainability of this rapid growth. The initial surge in sales was largely driven by early adopters, and the market now confronts challenges such as high prices and limited charging infrastructure, while EVs still trail gas cars in overall market share. Despite these concerns, projections suggest that even a slowdown to 30-40 percent growth in EV sales for 2024 would align with the law's emission goals.

The renewable energy sector's progress is less straightforward. Despite achieving a record addition of 32.3 gigawatts of clean electricity capacity in the past year, the pace falls short of the projected 46 to 79 gigawatts needed annually to meet the United States' climate objectives. While there is potential for about 60 gigawatts of projects in the pipeline for this year, not all are expected to materialize on schedule, indicating a lag in the deployment of new renewable energy sources.

Logistical challenges are a significant barrier to scaling up renewable energy, especially as EV-driven electricity demand rises in the coming years. Lengthy grid connection processes, permitting delays, and local opposition hinder wind and solar project developments. Moreover, ambitious plans for offshore wind farms are hampered by supply chain issues and regulatory constraints.

To achieve the Inflation Reduction Act's ambitious targets, the United States needs to add 70 to 126 gigawatts of renewable capacity annually from 2025 to 2030—a formidable task given the current logistical and regulatory bottlenecks. The analysis underscores the urgency of addressing these non-cost barriers to unlock the full potential of the law's clean energy and emissions reduction ambitions.

In addition to promoting clean energy generation and EV adoption, the Inflation Reduction Act has spurred domestic manufacturing of clean energy technologies. With $44 billion invested in U.S. clean-energy manufacturing last year, this aspect of the law has seen considerable success, and permanent clean energy tax credits are being debated to sustain momentum, demonstrating the Act's capacity to drive economic and industrial transformation.

The law's impact extends to emerging clean energy technologies, offering tax incentives for advanced nuclear reactors, renewable hydrogen production, and carbon capture and storage projects. While these initiatives hold promise for further emissions reductions, their development and deployment are still in the early stages, with tangible outcomes expected in the longer term.

While the Inflation Reduction Act has catalyzed significant strides in certain areas of the United States' clean energy transition, including an EV inflection point in adoption trends, it faces substantial hurdles in fully realizing its objectives. Overcoming logistical, regulatory, and market challenges will be crucial for the nation to stay on course toward its ambitious climate goals, underscoring the need for continued innovation, investment, and policy refinement in the journey toward a sustainable energy future.
