More than half of new U.S. electric-generating capacity in 2023 will be solar

Canada Electricity Decarbonization Costs indicate challenging greenhouse gas reductions across a fragmented grid, with wind, solar, nuclear, and natural gas tradeoffs, significant GDP impacts, and Net Zero targets constrained by intermittency and limited interties.

Key Points

Costs to cut power CO2 via wind, solar, gas, and nuclear, considering grid limits, intermittency, and GDP impacts.

✅ Alberta model: eliminate coal; add wind, solar, gas; 26-40% CO2 cuts

✅ Nuclear option enables >75% cuts at higher but feasible system costs

✅ National costs 1-2% GDP; reserves, transmission, land, and waste not included

Along with many western developed countries, Canada has pledged to reduce its greenhouse gas emissions by 40–45 percent by 2030 from 2005 emissions levels, and to achieve net-zero emissions by 2050.

This is a huge challenge that, when considered on a global scale, will do little to stop climate change because emissions by developing countries are rising faster than emissions are being reduced in developed countries. Even so, the potential for achieving emissions reduction targets is extremely challenging as there are questions as to how and whether targets can be met and at what cost. Because electricity can be produced from any source of energy, including wind, solar, geothermal, tidal, and any combustible material, climate change policies have focused especially on nations’ electricity grids, and in Canada cleaning up electricity is viewed as critical to meeting climate pledges.

Canada’s electricity grid consists of ten separate provincial grids that are weakly connected by transmission interties to adjacent grids and, in some cases, to electricity systems in the United States. At times, these interties are helpful in addressing small imbalances between electricity supply and demand so as to prevent brownouts or even blackouts, and are a source of export revenue for provinces that have abundant hydroelectricity, such as British Columbia, Manitoba, and Quebec.

Due to generally low intertie capacities between provinces, electricity trade is generally a very small proportion of total generation, though electricity has been a national climate success in recent years. Essentially, provincial grids are stand alone, generating electricity to meet domestic demand (known as load) from the lowest cost local resources.

Because climate change policies have focused on electricity (viz., wind and solar energy, electric vehicles), and Canada will need more electricity to hit net-zero according to the IEA, this study employs information from the Alberta electricity system to provide an estimate of the possible costs of reducing national CO2 emissions related to power generation. The Alberta system serves as an excellent case study for examining the potential for eliminating fossil-fuel generation because of its large coal fleet, favourable solar irradiance, exceptional wind regimes, and potential for utilizing BC’s reservoirs for storage.

Using a model of the Alberta electricity system, we find that it is infeasible to rely solely on renewable sources of energy for 100 percent of power generation—the costs are prohibitive. Under perfect conditions, however, CO2 emissions from the Alberta grid can be reduced by 26 to 40 percent by eliminating coal and replacing it with renewable energy such as wind and solar, and gas, but by more than 75 percent if nuclear power is permitted. The associated costs are estimated to be some $1.4 billion per year to reduce emissions by at most 40 percent, or $1.9 billion annually to reduce emissions by 75 percent or more using nuclear power (an option not considered feasible at this time).

Based on cost estimates from Alberta, and Ontario’s experience with subsidies to renewable energy, and warnings that the switch from fossil fuels to electricity could cost about $1.4 trillion, the costs of relying on changes to electricity generation (essentially eliminating coal and replacing it with renewable energy sources and gas) to reduce national CO2 emissions by about 7.4 percent range from some $16.8 to $33.7 billion annually. This constitutes some 1–2 percent of Canada’s GDP.

The national estimates provided here are conservative, however. They are based on removing coal-fired power from power grids throughout Canada. We could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset—available wind and solar energy might be lower than indicated by the available data. To take this into account, a reserve market is required, but the costs of operating such a capacity market were not included in the estimates provided in this study. Also ignored are the costs associated with the value of land in other alternative uses, the need for added transmission lines, environmental and human health costs, and the life-cycle costs of using intermittent renewable sources of energy, including costs related to the disposal of hazardous wastes from solar panels and wind turbines.

Bioo Soil-Generated Electricity turns biological batteries and photosynthesis into renewable energy, powering IoT sensors for smart farming and lighting, using microbe-powered soil electrochemistry to cut battery waste, reduce costs, and scale sustainable agritech infrastructure.

Key Points

Bioo Soil-Generated Electricity powers IoT sensors and lighting using soil microbes, delivering clean renewable energy.

✅ Microbe-driven soil batteries replace disposable chemical cells

✅ Powers IoT agritech sensors for moisture, pH, and temperature

✅ Cuts maintenance and costs while enabling sustainable farming

SCENES shines a spotlight on youth around the world that are breaking down barriers and creating change. The character-driven short films will inspire and amaze, as these young change-makers tell their remarkable stories.

Pablo Vidarte is a born inventor. At the age of eight, he was programming video games. By 16, he was challenging NASA and competing with the Spanish army to enhance the efficiency of external combustion engines. "I wanted to perfect a system that NASA did in 2002 oriented to powering cars. I was able to increase that efficiency by 60 per cent, which was pretty cool," Pablo explained. Aged 18, he created his first company specialising in artificial intelligence. A year later, he founded Bioo, a revolutionary startup that generates electricity from plants' photosynthesis.

"Imagine, being in the middle of a park or a street and being able to touch a plant and turn on the lights of that specific area," Pablo told Scenes. "Imagine storing the memories of humanity itself in nature. Imagine storing voice messages in a library that is an open field where you can go and touch the plants and communicate and interact with them. That's what we do at Bioo," he added.

The creation of Bioo, however, was not a walk in the park. Pablo relied on nanotechnology engineers and biologists volunteering their time to turn his idea of biological batteries, inspired by biological design, into a reality. It took a year for a prototype to be created and an investor to come on board. Today, Bioo is turning plants into biological switches, generating renewable energy from nature, and transforming the environment.

"We realised that we were basically killing the planet, and then we invented things like solar panels and solutions like peer-to-peer energy that we're able to prevent things from getting worse, but the next step is to be able to reverse the whole equation to revive that planet that we're starting to lose," the 25-year-old explained.

Batteries creating electricity from soil
Bioo has designed biological batteries that generate electricity from the energy released when organic soil decomposes. Like traditional batteries, they have an anode and a cathode, but instead of using materials like lithium to power them, organic matter is used as fuel. When microorganisms break down the organic soil, electrons are released. These electrons are then transported from the anode to the cathode, and a current of electricity is created. The batteries come in the shape of a rectangular box and can be dug into any fertile soil. They produce up to 200Wh a year per square metre, and just as some tidal projects use underwater kites to harvest energy, these systems tap natural processes.

Bioo's batteries are limited to low-power applications, but they have grown in popularity and are set to transform the agriculture industry.

Cost savings for farmers
Farmers can monitor their crops using a large network of sensors. The sensors allow them to analyse growing conditions, such as soil moisture, PH levels and air temperature. Almost 90 per cent of the power used to run the sensors come from chemical batteries, which deplete, underscoring the renewable energy storage problem that new solutions target.

"The huge issue is that chemical batteries need to be replaced every single year. But the problem is that you literally need an army of people replacing batteries and recalibrating them," Pablo explains. "What we do, it's literally a solution that is hidden, and that's nourishing from the soil itself and has the same cost as using chemical batteries. So the investment is basically returned in the first year," Pablo added.

Bioo has partnered with Bayer, a leading agricultural producer, to trial their soil-powered sensors on 50 million hectares of agricultural land. If successful, the corporation could save €1.5 billion each year. Making it a game-changer for farmers around the world.

A BioTech World
In addition to agriculture, Bioo's batteries are now being installed in shopping centres, offices and hospitals to generate clean power for lighting, while other companies are using ocean and river power to diversify clean generation portfolios.

Pablo's goal is to create a more environmentally efficient world, so shares his technology with international tech companies as green hydrogen projects scale globally. "I wanted to do something that could really mean a change for our world. Our ambition right now is to create a biotech world, a world that is totally interconnected with nature," he said.

As Bioo continues to develop its technology, Pablo believes that soil-generated electricity will become a leader in the global energy market, aligning with progress toward cheap, abundant electricity becoming a reality worldwide.

Accelerate Kootenays EV charging stations expand along Highway 3, adding DC fast charging and Level 2 plugs to cut range anxiety for electric vehicles in B.C., linking communities like Castlegar, Greenwood, and the Alberta border.

Key Points

A regional network of DC fast and Level 2 chargers along B.C.'s Highway 3 to reduce range anxiety and boost EV adoption.

✅ 13 DC fast chargers plus 40 Level 2 stations across key hubs

✅ 20-minute charging stops reduce range anxiety on Highway 3

✅ Backed by BC Hydro, FortisBC, and regional districts

The Kootenays are B.C.'s electric powerhouse, and as part of B.C.'s EV push the region is making significant advances to put electric cars on the road.

The region's dams generate more than half of the province's electricity needs, but some say residents in the region have not taken to electric cars, for instance.

Trish Dehnel is a spokesperson for Accelerate Kootenays, a multi-million dollar coalition involving the regional districts of East Kootenay, Central Kootenay and Kootenay Boundary, along with a number of corporate partners including Fortis B.C. and BC Hydro.

She says one of the major problems in the region — in addition to the mountainous terrain and winter driving conditions — is "range anxiety."

That's when you're not sure your electric vehicle will be able to make it to your destination without running out of power, she explained.

Now, Accelerate Kootenays is hoping a set of new electric charging stations, part of the B.C. Electric Highway project expanding along Highway 3, will make a difference.

No more 'range anxiety'

The expansion includes 40 Level 2 stations and 13 DC Quick Charging stations, mirroring BC Hydro's expansion across southern B.C. strategically located within the region to give people more opportunities to charge up along their travel routes, Dehnel said.

"We will have DC fast-charging stations in all of the major communities along Highway 3 from Greenwood to the Alberta border. You will be able to stop at a fast-charging station and, thanks to faster EV charging technology, charge your vehicle within 20 minutes," she said.

Castlegar car salesman Terry Klapper — who sells the 2017 Chevy Bolt electric vehicle — says it's a great step for the region as sites like Nelson's new fast-charging station come online.

"I guarantee that you'll be seeing electric cars around the Kootenays," he said.

"The interest the public has shown … [I mean] as soon as people found out we had these Bolts on the lot, we've had people coming in every single day to take a look at them and say when can I finally purchase it."

The charging stations are set to open by the end of next year.

UK Renewable Energy Auction secures 10 GW for the grid at record-low costs, led by offshore wind, floating wind, solar, and onshore wind, with inflation-indexed CfDs delivering £37/MWh strike prices and enhanced energy security.

Key Points

Government CfDs add 10 GW of low-cost renewables to the UK grid via offshore wind, floating wind, and solar.

✅ 10 GW capacity: 7 GW offshore wind, 2.2 GW solar, 0.9 GW onshore wind

✅ Record-low £37/MWh offshore; floating wind at £87/MWh CfD strikes

✅ 15-year indexed contracts cut exposure to volatile gas prices

The United Kingdom will add 10 gigawatts (GW) of renewable energy capacity to its power grid at one-quarter the cost of fossil gas after concluding its biggest-ever renewable energy auction for new renewable supplies.

The “remarkable new UK renewable auction” will meet one-eighth of the country’s current electricity demand at record low prices of just £37 per megawatt-hour for offshore wind and £87 for floating offshore systems (a dynamic echoed as wind power gains in Canada across other markets), tweeted Carbon Brief Deputy Editor Simon Evans.

“The government is increasing its reliance on a local supply of renewables amid soaring UK power prices driven by a surge in the cost of natural gas following Russia’s invasion of Ukraine,” Bloomberg Green reports. Offshore wind energy “will add about seven gigawatts of clean power capacity to the nation’s fleet from 2026, bringing Britain closer to its target of installing 50 gigawatts by the end of the decade.”

The awards also include 2.2 gigawatts (that’s 2.2 billion watts) of solar and 900 megawatts of onshore wind, even as the UK faces a renewables backlog on some projects, Bloomberg says.

“Eye-watering gas prices are hitting consumers across Europe,” said UK Business and Energy Secretary Kwasi Kwarteng. “The more cheap, clean power we generate within our own borders, the better protected we will be from volatile gas prices that are pushing up bills.”

Citing government figures, Bloomberg says wind generation costs came in 5.8% lower than the previous auction in 2019, reflecting momentum in a sector set to become a trillion-dollar business this decade. Some of the winning bidders included Ørsted, Iberdrola’s Scottish Power unit, Vattenfall, and a consortium of AB Ignitis Grupe, EDP Renovaveis, and Engie.

“Offshore wind power costs have fallen dramatically in recent years as the UK supported the industry to scale up and industrialize production of larger, more efficient turbines,” the news story states. Now, “the decline in price developers are willing to accept comes even after the cost of wind turbines rose in recent months as prices increased for key metals like steel and supply chain disruptions created expensive delays.”

The 15-year, fixed-price contracts will be adjusted for inflation when the turbines are ready to start delivering electricity, offering lessons for the U.S. wind sector on contract design.

California Gas Car Ban 2035 signals a shift to electric vehicles, raising grid reliability concerns, charging demand, and renewable energy challenges across solar, wind, and storage, amid rolling blackouts and carbon-free power mandates.

Key Points

An order ending new gasoline car sales by 2035 in California, accelerating EV adoption and pressuring the power grid.

✅ 25% EV fleet could add 232.5 GWh/day charging demand by 2040

✅ Solar and wind intermittency strains nighttime home charging

✅ Grid upgrades, storage, and load management become critical

On September 23, California Gov. Gavin Newsom issued an executive order that will ban the sale of gasoline-powered cars in the Golden State by 2035. Ignoring the hard lessons of this past summer, when California’s solar- and wind-reliant electric grid underwent rolling blackouts, Newsom now adds a huge new burden to the grid in the form of electric vehicle charging, underscoring the need for a much bigger grid to meet demand. If California officials follow through and enforce Newsom’s order, the result will be a green new car version of a train wreck.

In parallel, the state is moving on fleet transitions, allowing electric school buses only from 2035, which further adds to charging demand.

Let’s run some numbers. According to Statista, there are more than 15 million vehicles registered in California. Per the U.S. Department of Energy, there are only 256,000 electric vehicles registered in the state—just 1.7 percent of all vehicles, a share that will challenge state power grids as adoption grows.

Using the Tesla Model3 mid-range model as a baseline for an electric car, you’ll need to use about 62 kilowatt-hours (KWh) of power to charge a standard range Model 3 battery to full capacity. It will take about eight hours to fully charge it at home using the standard Tesla NEMA 14-50 charger, a routine that has prompted questions about whether EVs could crash the grid by households statewide.

Now, let’s assume that by 2040, five years after the mandate takes effect, also assuming no major increase in the number of total vehicles, California manages to increase the number of electric vehicles to 25 percent of the total vehicles in the state. If each vehicle needs an average of 62 kilowatt-hours for a full charge, then the total charging power required daily would be 3,750,000 x 62 KWh, which equals 232,500,000 KWh, or 232.5 gigawatt-hours (GWh) daily.

Utility-scale California solar electric generation according to the energy.ca.gov puts utility-scale solar generation at about 30,000 GWh per year currently. Divide that by 365 days and we get 80 GWh/day, predicted to double, to 160 GWh /day. Even if we add homeowner rooftop solar, and falling prices for solar and home batteries in the wake of blackouts, about half the utility-scale, at 40 GWh/day we come up to 200 GW/h per day, still 32 GWh short of the charging demand for a 25% electric car fleet in California. Even if rooftop solar doubles by 2040, we are at break-even, with 240GWh of production during the day.

Bottom-line, under the most optimistic best-case scenario, where solar operates at 100% of rated capacity (it seldom does), it would take every single bit of the 2040 utility-scale solar and rooftop capacity just to charge the cars during the day. That leaves nothing left for air conditioning, appliances, lighting, etc. It would all go to charging the cars, and that’s during the day when solar production peaks.

But there’s a much bigger problem. Even a grade-schooler can figure out that solar energy doesn’t work at night, when most electric vehicles will be charging at homes, even as some officials look to EVs for grid stability through vehicle-to-grid strategies. So, where does Newsom think all this extra electric power is going to come from?

The wind? Wind power lags even further behind solar power. According to energy.gov, as of 2019, California had installed just 5.9 gigawatts of wind power generating capacity. This is because you need large amounts of land for wind farms, and not every place is suitable for high-return wind power.

In 2040, to keep the lights on with 25 percent of all vehicles in California being electric, while maintaining the state mandate requiring all the state’s electricity to come from carbon-free resources by 2045, California would have to blanket the entire state with solar and wind farms. It’s an impossible scenario. And the problem of intermittent power and rolling blackouts would become much worse.

And it isn’t just me saying this. The U.S. Environmental Protection Agency (EPA) agrees. In a letter sent by EPA Administrator Andrew Wheeler to Gavin Newsom on September 28, Wheeler wrote:

“[It] begs the question of how you expect to run an electric car fleet that will come with significant increases in electricity demand, when you can’t even keep the lights on today.

“The truth is that if the state were driving 100 percent electric vehicles today, the state would be dealing with even worse power shortages than the ones that have already caused a series of otherwise preventable environmental and public health consequences.”

California’s green new car wreck looms large on the horizon. Worse, can you imagine electric car owners’ nightmares when California power companies shut off the power for safety reasons during fire season? Try evacuating in your electric car when it has a dead battery.

Gavin Newsom’s “no more gasoline cars sold by 2035” edict isn’t practical, sustainable, or sensible, much like the 2035 EV mandate in Canada has been criticized by some observers. But isn’t that what we’ve come to expect with any and all of these Green New Deal-lite schemes?

Global Renewable Capacity Additions 2023 surge on policy momentum, high fossil prices, and energy security, with solar PV and wind leading growth as grids expand and manufacturing scales across China, Europe, India, and the US.

Key Points

Record solar PV and wind growth from policy and energy security, adding 440+ GW toward 4,500 GW total capacity in 2024.

✅ Solar PV to supply two-thirds of additions; rooftop demand rising.

✅ Wind rebounds ~70% as delayed projects complete in China, EU, US.

✅ Grid upgrades and better permitting, auctions key for 2024 growth.

Global additions of renewable power capacity are expected to jump by a third this year as growing policy momentum, higher fossil fuel prices and energy security concerns drive strong deployment of solar PV and wind power, building on a record year for renewables in 2016, according to the latest update from the International Energy Agency.

The growth is set to continue next year with the world’s total renewable electricity capacity rising to 4 500 gigawatts (GW), equal to the total power output of China and the United States combined, and in the United States wind power has surged in the electricity mix, says the IEA’s new Renewable Energy Market Update, which was published today.

Global renewable capacity additions are set to soar by 107 gigawatts (GW), the largest absolute increase ever, to more than 440 GW in 2023. The dynamic expansion is taking place across the world’s major markets. Renewables are at the forefront of Europe’s response to the energy crisis, accelerating their growth there. New policy measures are also helping drive significant increases in the United States, where solar and wind growth remains strong, and India over the next two years. China, meanwhile, is consolidating its leading position and is set to account for almost 55% of global additions of renewable power capacity in both 2023 and 2024.

“Solar and wind are leading the rapid expansion of the new global energy economy. This year, the world is set to add a record-breaking amount of renewables to electricity systems – more than the total power capacity of Germany and Spain combined,” said IEA Executive Director Fatih Birol. “The global energy crisis has shown renewables are critical for making energy supplies not just cleaner but also more secure and affordable – and governments are responding with efforts to deploy them faster. But achieving stronger growth means addressing some key challenges. Policies need to adapt to changing market conditions, and we need to upgrade and expand power grids to ensure we can take full advantage of solar and wind’s huge potential.”

Solar PV additions will account for two-thirds of this year’s increase in renewable power capacity and are expected to keep growing in 2024, according to the new report. The expansion of large-scale solar PV plants is being accompanied by the growth of smaller systems. Higher electricity prices are stimulating faster growth of rooftop solar PV, which is empowering consumers to slash their energy bills, and in the United States renewables' share is projected to approach one-fourth of electricity generation.

At the same time, manufacturing capacity for all solar PV production segments is expected to more than double to 1 000 GW by 2024, led by China's solar PV growth and increasing supply diversification in the United States, where wind, solar and battery projects dominate the 2023 pipeline, India and Europe. Based on those trends, the world will have enough solar PV manufacturing capacity in 2030 to comfortably meet the level of annual demand envisaged in the IEA’s Net Zero Emissions by 2050 Scenario.

Wind power additions are forecast to rebound sharply in 2023 growing by almost 70% year-on-year after a difficult couple of years in which growth was slugging, even as wind power still grew despite Covid-19 challenges. The faster growth is mainly due to the completion of projects that had been delayed by Covid-19 restrictions in China and by supply chain issues in Europe and the United States. However, further growth in 2024 will depend on whether governments can provide greater policy support to address challenges in terms of permitting and auction design. In contrast to solar PV, wind turbine supply chains are not growing fast enough to match accelerating demand over the medium-term. This is mainly due to rising commodity prices and supply chain challenges, which are reducing the profitability of manufacturers.

The forecast for renewable capacity additions in Europe has been revised upwards by 40% from before Russia’s invasion of Ukraine, which led many countries to boost solar and wind uptake to reduce their reliance on Russian natural gas. The growth is driven by high electricity prices that have made small-scale rooftop solar PV systems more financially attractive and by increased policy support in key European markets, especially in Germany, Italy and the Netherlands.
