Germany Solar Boom is accelerating amid energy security pressures, with photovoltaic capacity surging as renewables displace gas. Policy incentives, grid upgrades, and storage, plus agrivoltaics and rooftop systems, position solar as cornerstone of decarbonization.

Key Points

Germany Solar Boom is rapid PV growth enhancing energy security, cutting emissions, and expanding domestic, low-carbon electricity.

✅ Targets 250 GW PV by 2032 to meet rising electricity demand.

✅ Rooftop, agrivoltaics, and BIPV reduce land use and grid stress.

✅ Diversifies supply chains beyond China; boosts storage and flexibility.

Europe is in crisis mode. Climate change, increasing demand for energy, the war in Ukraine and Russia's subsequent throttling of oil and gas deliveries have pushed the continent into a new era.

Germany has been trapped in a corner. The country relies heavily on cheap imported natural gas to run its industries. Some power plants also use gas to produce electricity. Finding enough substitutes quickly is nearly impossible.

Ideas to prevent a looming power crisis in Germany have ranged from reducing demand to keeping nuclear power plants online past their official closing date at the end of the year. Large wind turbines are doing their part, but many people don't want them in their backyard.

Green activists have long believed renewable energies are the answer to keeping the lights on. But building up these capabilities takes time. Now many experts once again see solar power as a shining light at the end of the tunnel, as global renewables set fresh records worldwide. Some say a solar boom is in the making.

Before the war in Ukraine put energy security at the forefront, the new German government had already pledged that renewable sources — wind and solar — would make up 80% of electricity production by 2030 instead of 42% today. By 2035, electricity generation should be carbon neutral.

It is an ambitious plan, but the country seems to be on its way. July was the third month in a row when solar power output soared to a record level, trade publication pv magazine reported, and clean energy's share reached about 50% in Germany according to recent assessments. For the month, photovoltaic (PV) systems generated 8.23 ​​terawatt hours of power, around a fifth of net electricity production. They were only behind lignite-fired power plants, which brought in nearly 22% of net production.

Last year, Germany added more than 5 gigawatts of solar power capacity, 10% more than in 2020. That took the total solar power capacity to 59 gigawatts, overtaking installed onshore wind power capacity in Germany, pv magazine said in January. Last year's solar production was about 9% of gross electricity consumption, according to Harry Wirth, who is head of photovoltaic modules and power plant research at the Fraunhofer Institute for Solar Energy Systems in Freiburg.

"For 2032, the government target is around 250 gigawatts of solar energy. According to their estimates, electricity consumption will increase to 715 terawatt hours by 2030," Wirth told DW. A different study by consultancy McKinsey says this is the lower limit. "So if we assume 730 terawatt hours for 2032, we would be at around 30% photovoltaic electricity in gross electricity consumption," he added. 

The energy expert also envisions great potential to install more solar panels without taking up valuable land. Besides adding them on top of parking garages or buildings, photovoltaic parts can be integrated into the exterior of buildings or even on the outside of e-vehicles. This would "not only produce electricity on surfaces already in use, but it would also create synergies in its own application," said Wirth.

Foreign investment in German solar
It is not just researchers that are taking note. Big businesses are stepping in too. In July, Portuguese clean energy firm EDP Renovaveis (EDPR) announced it had agreed to take a 70% interest in Germany's Kronos Solar Projects, a solar developer, for €250 million ($254 million).

The Munich-based company has a portfolio of 9.4 gigawatts of solar projects in different stages of development in Germany, France, the Netherlands and the UK, according to the press release announcing the purchase. Germany represents close to 50% of the acquired solar portfolio.

EDPR, which claims to be the fourth-largest renewable energy producer worldwide, said it generated 17.8 terawatt hours of clean energy in the first half of 2022.

Miguel Stilwell d'Andrade, chief executive of EDPR and its parent EDP, said they have great expectations from Germany in particular as "it is a key market in Europe with reinforced renewable growth targets." 

Fabian Karthaus is one of the first farmers in Germany to grow raspberries and blueberries under photovoltaic panels. His solar field near the city of Paderborn in northwestern Germany is 0.4 hectares (about 1 acre), but he would like to expand it to 10. He could then generate enough electricity for around 4,000 households — and provide more berries for supermarkets.

Germany was once a leader in solar power. For many years the country enjoyed a large share of the world's total solar capacities. A lot of that early success had to do with innovative government support. That support, however, proved too successful for some as a fall in wholesale electricity prices in Northern Europe hurt the profits of power companies, leading to calls for a change in the rules.

Updated regulations, and changes to the Renewable Energy Sources Act that reduced feed-in tariffs slowed things down. Feed-in tariffs usually grant long-term grid access and above-market price guarantees in an effort to support fledgling industries.

With less direct financial incentives, the industry was neglected leaving it open for competitors. The pace of solar infrastructure growth has also been hampered by issues of red tape, supply chain backlogs, a lack of skilled technicians and, despite solar-plus-storage now undercutting conventional power in Germany, a shortage of storage for electricity produced when it is not needed.

Now the war in Ukraine and Europe's dependency on Russia is refocusing efforts and "will strengthen the determination for an ambitious PV expansion," said Wirth. But the biggest challenge to the region's solar industry remains China.

Public buildings can play a big role, not just because of their size, but because the government is in charge of them

An overreliance on China
China took an early interest in photovoltaic technology and soon galloped past countries like the US, Japan and Germany thanks to huge state subsidies that manufacturers enjoyed. Today, it has become the place to go for all things solar, even as Europe turns to US solar equipment suppliers to diversify procurement.

A new report from the International Energy Agency puts it into numbers. "China has invested over $50 billion in new PV supply capacity — 10 times more than Europe — and created more than 300,000 manufacturing jobs across the solar PV value chain since 2011."

Today China has over 80% of all solar panel manufacturing capacity and is home to the top-10 suppliers of photovoltaic manufacturing equipment. Such a high concentration has led to some incredible realities, like the fact that "one out of every seven panels produced worldwide is manufactured by a single facility," according to the report.

These economies of scale have brought down costs, and the country can make solar components 35% cheaper than in Europe. This gives China outsized power and makes the industry susceptible to supply chain bottlenecks. To diversify the industry and get back some of this market, Europe needs to invest in innovation and make solar growth a top priority.

Germany has several high-tech photovoltaic manufacturers and research institutes. But it only has one manufacturer of solar cells specializing in high-performance heterojunction technology, says Wirth. Yet even though the European photovoltaic industry is fragmented and not what it once was, he is still counting on big demand for solar technology in the foreseeable future, with markets like Poland accelerating adoption across the region.

DOE LNG Export Approvals expand flexibility for Cheniere's Sabine Pass and Corpus Christi to ship to non-FTA countries, boosting U.S. supply to Europe while advancing methane emissions reductions and strengthening global energy security.

Key Points

DOE LNG export approvals authorize Sabine Pass and Corpus Christi to sell full-capacity LNG to non-FTA markets.

✅ Exports allowed to any non-FTA country, including Europe

✅ Capacity covers Sabine Pass and Corpus Christi terminals

✅ DOE targets methane reductions across oil and gas

The U.S. Department of Energy (DOE) today issued two long-term orders authorizing liquefied natural gas (LNG) exports from two current operating LNG export projects, Cheniere Energy Inc.’s Sabine Pass in Louisiana and Corpus Christi in Texas, following a recent deep freeze that slammed the American energy sector.

The two orders allow Sabine Pass and Corpus Christi additional flexibility to export the equivalent of 0.72 billion cubic feet per day of natural gas as LNG to any country with which the U.S. does not have a free trade agreement, including all of Europe, such as the UK natural gas market as well.

While U.S. exporters are already exporting at or near their maximum capacity, with today's issuances, every operating U.S. LNG export project has approval from DOE to export its full capacity to any country where not prohibited by U.S. law or policy constraints in place.

The U.S. is now the top global exporter of LNG and exports are set to grow an additional 20% beyond current levels by the end of this year as additional capacity comes online, even as a domestic energy crisis influences electricity and gas markets.  In January 2022, U.S. LNG supplied more than half of the LNG imports into Europe for the month.

With the expected rise in LNG exports, DOE is particularly focused on driving down methane emissions in the oil and gas sector both domestically and abroad, leveraging the deep technical expertise of the Department, and supporting nuclear innovation as well.

U.S. LNG remains an important component to global energy security worldwide and DOE remains committed to finding ways to help our allies and trading partners, including support to Ukraine and others with the energy supplies they need while continuing to work to mitigate the impact of climate change.

U.S. Offshore Wind Power Strategy leverages UK offshore wind lessons, contract auctions, and supply chains to scale renewable energy, build wind farms, cut emissions, create jobs, and modernize the grid to meet 2030 climate goals.

Key Points

U.S. plan to scale offshore wind via UK-style contracts, turbines, and supply chains to meet 2030 clean energy goals

✅ Contract-for-difference price guarantees de-risk projects

✅ Scale turbines and ports to cut LCOE and boost capacity

✅ Build coastal grids, transmission, and workforce by 2030

As President Joe Biden’s administration puts its muscle behind wind power with plans to develop large-scale wind farms along the entire United States coastline, the administration can look at how the windiest nation in Europe is transforming its energy grid for an example of how to proceed.

In the search for renewable sources of energy, the United Kingdom has embraced wind power. In 2020, the country generated as much as 24 percent of its electricity from wind power across the grid — enough to supply 18.5 million homes, according to government statistics. 

With usually reliable winds, the U.K. currently has the highest number of offshore turbines installed in the world, with China at a close second.

Experts and industry leaders say it offers valuable lessons on creating a viable market for wind power at the ambitious scale the Biden administration hopes to meet in order to confront climate change and help transition the U.S. economy to renewable energy.

“The U.S. is going to benefit hugely from the early investment that European governments have put into offshore wind,” said Oliver Metcalfe, a wind power analyst at BloombergNEF in London, an independent research group.

Big American plans
On Oct. 13, the White House announced ambitious offshore wind plans to lease federal waters off of the East and West Coasts and Gulf of Mexico to develop commercial wind farms.

The move is part of Biden’s goal to have 30,000 megawatts of offshore wind power produced in the United States by 2030, with projects such as New York's record-setting approval highlighting the momentum. The White House says that would generate enough electricity to power more than 10 million homes and in the process create 77,000 jobs. 

But there is a chasm between where the U.S. is now and where it wants to be within the next decade when it comes to offshore wind power.

“We’re the first generation to understand the science and implications of climate change and we’re the last generation to be able to do something about it.”

The U.S. is not new to wind power; onshore wind in states such as Texas, Oklahoma and Iowa supplied 8.2 percent of the country’s total electricity generation in 2020, according to the U.S. Department of Energy. 

But despite its long coastlines, offshore wind has been a largely untapped resource in the U.S. With a population of about 332 million people, the U.S. currently has just two operational offshore wind farms — off Rhode Island and Virginia — with the capacity to produce 42 megawatts of electricity between them, far from the 1 gigawatt on-grid milestone many are watching. 

In contrast, the U.K., with a population of 67 million people, has 2,297 offshore wind turbines with the capacity to produce 10,415 megawatts of electricity.

Power station or a park?
Just outside of central Glasgow, the host city for the U.N. climate change conference known as COP26, the fruits of years of effort to move away from fossil fuels can be seen and heard

International financiers, including the World Bank are helping developing countries scale wind projects to meet climate goals.

Whitelee Windfarm, the U.K.’s largest onshore wind farm, spreads across 30 square miles on the Eaglesham Moor and includes more than 80 miles of trails for walking, cycling and horseback riding.

With its 539 megawatt capacity, it generates enough electricity for 350,000 homes — more than half the population of Glasgow. 

On a recent gusty fall day, Ian and Fiona Gardner, both 71, were walking their dogs among the wind farm’s 360-foot-tall turbines  

“This is a major contribution to Scotland, to become independent from oil by 2035,” Ian Gardner, an accountant, said. 

Thanks to the rapid technological advances in turbine technology, this wind farm that was completed in 2009, is now practically old school. The latest crop of onshore turbines typically generate double the current capacity of Whitelee’s turbines.

“It took us 20 years to build 2 gigawatts of power. And we’re going to double that in five  years,” said McQuade, an economist. “We can do that because machines are big, efficient, cheap and the supply chain is there.” 

The biggest operational offshore wind farm in the world right now, Hornsea Project One, is about 75 miles off England’s Yorkshire coast in the North Sea.

Owned and operated by Orsted, a former Danish oil and gas giant, in partnership with Global Infrastructure Partners, its 174 turbines have the capacity to generate 1.2 gigawatts — enough to power over 1 million homes and roughly equivalent to a nuclear power plant. 

Benj Sykes, Vice President of U.K. Offshore Wind at Orsted, called Hornsea One a “game changer” in a recent phone interview, citing it as an example of how the industry has scaled up its output to compete with traditional power plants.

But massive projects like Hornsea One took decades to get up and running, as well as government help. According to Malte Jansen, a research associate at the Centre of Environmental Policy at Imperial College London, the British government helped facilitate a “paradigm shift” in renewable energy in 2013.

The electricity market reform policy set up a framework to incentivize investment in offshore wind farms by creating an auction system that guarantees electricity prices to developers in 15-year contracts, alongside new contract awards that add 10 GW to the U.K. grid. 

This means there is no upside in terms of market price fluctuation, but there is no downside either. The policy essentially “de-risked the investment,” Jansen said.

The state contracts allowed the industry to innovate and learn how to develop even larger and more efficient turbines with blades that stretch as long as 267 feet, about three-quarters the size of a U.S. football field. 

While this approach helped companies and investors, it will also have an unintended beneficiary — the U.S., Metcalfe from BloombergNEF said. 

Developers are “taking the lessons they’ve learned building projects in Europe, the cost reductions that they’ve achieved building projects in Europe and are now bringing those to the U.S. market,” he said.

Oxford Battery Energy Storage Project will store surplus renewable power near South-West Oxford and Woodstock, improving grid stability, peak shaving, and reliability, pending IESO approval and Hydro One transmission interconnection in Ontario.

Key Points

A Boralex battery project in South-West Oxford storing surplus power for Woodstock at peak demand pending IESO approval.

✅ 2028 commercial operation target

✅ Connects to Hydro One transmission line

✅ Peak shaving to stabilize grid costs

A Quebec-based renewable energy company is proposing to build a battery energy storage system in Oxford County near Woodstock.

The Oxford battery energy storage project put forward by Boralex Inc., if granted approval, would be ready for commercial operation in 2028. The facility would be in the Township of South-West Oxford, but also would serve Woodstock businesses and residences, supported by provincial disconnect moratoriums for customers, due to the city’s proximity to the site.

Battery storage systems charge when energy sources produce more energy than customers need, and, complementing Ontario’s energy-efficiency programs across the province, discharge during peak demand to provide a reliable, steady supply of energy.

Darren Suarez, Boralex’s vice-president of public affairs and communications in North America, said, “The system we’re talking about is a very large battery that will help at times when the electric grid has too much energy on the system. We’ll be able to charge our batteries, and when there’s a need, we can discharge the batteries to match the needs of the electric grid.”

South-West Oxford is a region Boralex has pinpointed for a battery storage project. “We look at grid needs as a whole, and where there is a need for battery storage, and we’ve identified this location as being a real positive for the grid, to help with its stability, a priority underscored by the province’s nuclear alert investigation and public safety focus,” Suarez said.

Suarez could not provide an estimated cost for the proposed facility but said the project would add about 75 jobs during the construction phase, in a sector where the OPG credit rating remains stable. Once the site is operational, only one or two employees will be necessary to maintain the facility, he said.

Boralex requires approval from the Independent Electricity System Operator (IESO), the corporation that co-ordinates and integrates Ontario’s electricity system operations across the province, for the Oxford battery energy storage project.

Upon approval, the project will connect with an existing Hydro One transmission line located north of the proposed site. “[Hydro One] has a process to review the project and review the location and ensure we are following safety standards and protocols in terms of integrating the project into the grid, with broader policy considerations like Ottawa’s hydro heritage also in view, but they are not directly involved in the development of the project itself,” Suarez said.

The proposal has been presented to South-West Oxford council. South-West Oxford Mayor David Mayberry said, “(Council) is still waiting to see what permits are necessary to be addressed if the proposal moves forward.”

Mayberry said the Ministry of Natural Resources and Forestry also would be reviewing the proposed project.

Thornton Sand and Gravel, the location of the proposed facility, was viewed positively by Mayberry. “From a positive perspective, they’re not using farmland. There is a plus we’re not using farmland, but there is concern something could leak into the aquifer. These questions need to be answered before it can be to the satisfaction of the community,” Mayberry said.

An open house was held on Sept. 14 to provide information to residents. Suarez said about 50 people showed up and the response was positive. “Many people came out to see what we planned for the project and there was a lot of support for the location because of where it actually is, and how it integrates into the community. It’s considered good use of the land by many of the people that were able to join us on that day,” Suarez said.

The Quebec-based energy company has been operating in Ontario for nearly 15 years and has wind farms in the Niagara and Chatham-Kent regions.

Boralex also is involved in two other battery storage projects in Ontario. The Hagersville project is a 40-minute drive northwest of Hamilton, and the other is in Tilbury, a community in Chatham-Kent. Commercial operation for both sites is planned to begin in 2025.

South-West Oxford and Woodstock will see some financial benefits from the energy storage system, Suarez said.

“It will help to stabilize energy costs. It will contribute to really shaving the most expensive energy on the system off the system. They’re going to take electricity when it’s the least costly, taking advantage of Ontario’s ultra-low overnight pricing options and utilize that least costly energy and displace the most costly energy.”

US Plug-in EV Miles 2021 highlight BEV and PHEV growth, DOE and Argonne data, 19.1 billion electric miles, 6.1 TWh consumed, gasoline savings, rising market share, and battery capacity deployed across the US light-duty fleet.

Key Points

They represent 19.1 billion electric miles by US BEVs and PHEVs in 2021, consuming 6.1 TWh of electricity.

✅ 700 million gallons gasoline avoided in 2021

✅ $1.3 billion fuel cost savings estimated

✅ Cumulative 68 billion EV miles since 2010

Plug-in electric cars are gradually increasing their market share in the US (reaching about 4% in 2021), which starts to make an impact even as the U.S. EV market share saw a brief dip in Q1 2024.

The Department of Energy (DOE)’s Vehicle Technologies Office highlights in its latest weekly report that in 2021, plug-ins traveled some 19.1 billion miles (31 billion km) on electricity - all miles traveled in BEVs and the EV mode portion of miles traveled in PHEVs, underscoring grid impacts that could challenge state power grids as adoption grows.

This estimated distance of 19 billion miles is noticeably higher than in 2020 (nearly 13 billion miles), which indicates how quickly the electrification of driving progresses, with U.S. EV sales continuing to soar into 2024. BEVs noted a 57% year-over-year increase in EV miles, while PHEVs by 24% last year (mostly proportionally to sales increase).

According to Argonne National Laboratory's Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010–2021, the cumulative distance covered by plug-in electric cars in the US (through December 2021) amounted to 68 billion miles (109 billion miles).

U.S. Department of Transportation, Federal Highway Administration, December 2021 Traffic Volume Trends, 2022.

The report estimates that over 2.1 million plug-in electric cars have been sold in the US through December 2021 (about 1.3 million all-electric and 0.8 million plug-in hybrids), equipped with a total of more than 110 GWh of batteries, even as EV sales remain behind gas cars in overall market share.

It's also estimated that 19.1 billion electric miles traveled in 2021 reduced the national gasoline consumption by 700 million gallons of gasoline or 0.54%.

On the other hand, plug-ins consumed some 6.1 terawatt-hours of electricity (6.1 TWh is 6,100 GWh), which sounds like almost 320 Wh/mile (200 Wh/km), aligning with projections that EVs could drive a rise in U.S. electricity demand over time.

The difference between the fuel cost and energy cost in 2021 is estimated at $1.3 billion, with Consumer Reports findings further supporting the total cost advantages.

Cumulatively, 68 billion electric miles since 2010 is worth about 2.5 billion gallons of gasoline. So, the cumulative savings already is several billion dollars.

Those are pretty amazing numbers and let's just imagine that electric cars are just starting to sell in high volume, a trend that mirrors global market growth seen over the past decade. Every year those numbers will be improving, thus tremendously changing the world that we know today.

California Electric School Bus Mandate 2035 sets zero-emission requirements, outlines funding, state reimbursement, fleet electrification, infrastructure, and cost estimates, highlighting exemptions for frontier districts and alignment with clean transportation and climate policy goals.

Key Points

California's 2035 policy requires all new school buses be zero-emission, with funding and limited rural exemptions.

✅ Mandates zero-emission purchases for new school buses from 2035

✅ Estimates $5B transition cost with state reimbursement support

✅ Frontier districts may apply for 5-year extensions

California Governor Gavin Newsom has signed a new legislation requiring that from 2035, all newly ordered or contracted school buses must be zero-emission, a move aligned with California's push for expanded EV grid capacity statewide.

The state estimates that switching to electric school buses will cost around five billion dollars over the next decade, a projection reflecting electric bus challenges seen globally. That is because a diesel equivalent costs about 200,000 dollars less than a battery-electric version, as highlighted by critical analyses of California policy. And “the California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state.”

There are about 23,800 school buses on the road in California. About 500 are already electric, with conversion initiatives expected to expand the total, and 2,078 electric buses have been ordered.

There are – as always- exceptions to the rule. So-called “frontier districts,” which have less than 600 students or are in a county with a population density of less than ten persons per square mile, can file for a five-year extension, drawing on lessons from large electric bus fleets about route length and charging constraints. However, they must “reasonably demonstrate that a daily planned bus route for transporting pupils to and from school cannot be serviced through available zero-emission technology in 2035.”

Califonia is the fifth US state to mandate electric school buses, and jurisdictions like British Columbia are deploying electric school buses as well. Connecticut, Maryland, Maine, and New York implemented similar legislation, while California continues broader zero-emission freight adoption with Volvo VNR electric trucks entering service across the state.
