Economic Trends in Renewable Energy

#Solar is beating all expectations ☀️ Since the first commercially viable silicon solar cell was invented in 1954, it took 68 years for the world to surpass the first terawatt. It then took just two years to achieve the second terawatt. The amount of solar in the world has been roughly doubling every three years, but because it's coming off a low base, the effects aren't so obvious yet. Solar currently provides 6% of the world's electricity. At current rates, that would reach 12% in three years, 24% in six years and 48% in less than a decade. That is, assuming manufacturing and the grid can keep up. No other energy-producing technology has grown this quickly. Individual solar cells are becoming more and more efficient, and also more economical to produce at scale. The cost of a solar system nowadays is about 1/820th what it was in 1975. Prices have consistently fallen faster than predictions, passing several thresholds that were once thought impossible. Since 2000, the price of solar modules has already fallen from $20/W to $0.20/W. How long will it be before the world is installing 1 TW of solar a year? It's probably time to start scaling that recycling industry.. #energy #sustainability #renewables #energytransition

Our latest paper on market value of wind and solar energy With Clemens Stiewe, Alice Lixuan Xu and Anselm Eicke In the paper, we empirically study cross-border effects on the value of renewable energy: On one hand, interconnection is a flexibility resource that allows to export energy when it is locally abundant, benefitting renewables. On the other hand, wind and solar patterns are correlated between countries, so neighboring supply adds to the local one to depress domestic prices. We estimate both effects, using spatial panel regression on electricity market data from 2015 to 2023 from 30 European bidding zones. We find that, if wind market share increases both at home and in neighboring markets by one percentage point, the value factor of wind energy is reduced by just above 1 percentage point. For solar, this number is almost 4 percentage points.

Interesting graph from S&P Global Commodity Insights on the "Break-even estimates for 10-year PPAs starting in 2026". The average forecast price is for a pay-as-produced PPA 2026-2035 to recover new build, operating and financing costs. Unsurprisingly, we see quite large difference for solar, from 38 €/MWh in Spain to 115 €/MWh in Finland (some places are indeed sunnier). Wind is more stable and around 60 to 80 €/MWh. But how these prices compare with the capture prices? For solar, the capture prices were in 2024: 42 €/MWh in Spain, 47 €/MWh in Germany, and 39 €/MWh in France. So, for France and Germany, the capture prices are already quite well lower in 2024. The questions are: - Will the solar capture prices continue their downward trend? With the current expansion plan, it is likely that it will continue, in my opinion. - Or will consumption and storage compensate enough and offer some relief? - Will we still observe an appetite for more solar (both on corporate PPA and on government-back support such as Contract-for-difference)? Most probably, solar will increasingly be associated with storage in order to increase the capture rate. But how much storage compared to solar? This is certainly a dynamic question that will keep evolving with evolving costs and market prices. In any case, I believe that solar should also start providing power reserves in order to have another source of revenues.

South Korea just made solar panels mandatory for all big parking lots. New regulation: Any parking lot with over 80 spaces must install solar canopies. Not just new builds-existing sites too. It is a mandate, backed by the Ministry of Trade, Industry and Energy. The law covers both public and private land. Key drivers: → Grid resilience: Solar canopies add distributed generation capacity, supporting local grids and reducing peak load risks. → Land use efficiency: Parking lots are idle land. Solar carports turn them into energy assets without taking up new space. → Job creation: The policy will generate demand for solar and construction jobs, supporting local economies. For drivers, the benefits are immediate: • Protection from rain, snow, and extreme heat. • Cooler interiors, extending car lifespans and reducing AC demand-especially for EVs. • Onsite charging, making EV adoption easier and lowering range anxiety. Implementation starts now and projects will launch this month. Other markets are testing similar ideas. Arizona’s 657 kW solar carport system offsets emissions from 185,000 vehicles. New York is opening 400 million square feet of parking space for solar and EV charging. Germany has incentives for commercial rooftops, with clear impact on national energy independence. The common thread: More renewable energy generation means less reliance on fossil fuels, more energy sovereignty, and greater resilience against shocks. Takeaway for business leaders: Solar mandates for “idle” infrastructure are becoming common. They deliver measurable benefits-energy, economics, and public comfort. What should be the strategic response by businesses and boards? Prepare for regulatory shifts, assess asset portfolios, and act early to capture value. #renewableenergy #solar #energytransition #sustainability #policy #futureofenergy #businessstrategy

Energy security isn't a pipeline or a tanker: it's a rooftop - and Pakistan proves it While experts panic over the Strait of Hormuz and oil shocks from the Iran war, Pakistan is quietly winning. How? A massive, bottom-up solar revolution that Big Oil didn't see coming >25% of households now solar-powered >Solar energy share exploded from 3% to 32% in just 5 years >At least $12b saved in fuel imports since 2018 >$6.3b more saved this year alone It wasn't a master plan. It was millions of regular people, farmers, and businesses choosing cheap, reliable PV over expensive, volatile fossil fuels. Pakistan’s decentralized solar grid today acts as a national insurance policy https://buff.ly/yfABdFV

The energy transition is in full swing. But what happens when the wind doesn’t blow and the sun doesn’t shine? Germany aims for a nearly climate-neutral electricity supply by 2035. Political initiatives like the Renewable Energy Act (EEG) and the EU Green Deal are accelerating this shift, pushing for greater integration of renewables. To achieve this, integrating renewable energy sources isn’t enough—we need efficient ways to store energy. 🔋⚡ That’s where Battery Energy Storage Systems (BESS) come in. A recent study by the Technical University of Munich found that BESS can compensate for up to 80% of energy production fluctuations. This makes them a game changer for grid stability and energy security. By providing short-term (daily) storage, BESS helps balance grid fluctuations in real-time, ensuring that energy is available exactly when it’s needed. I see it firsthand in conversations with our partners: manufacturers looking for ways to stabilize their energy supply, municipalities trying to make the most of their solar power, or businesses facing rising electricity costs. They all have the same challenge: How can we store energy efficiently and use it exactly when we need it? The answer lies in intelligent battery storage, and we are helping to turn this potential into real-world solutions. Why does this matter? → Storing energy efficiently lowers costs for businesses and households. → When production fluctuates, battery storage ensures energy is still available—whether for a factory in full operation or a hospital that can’t afford downtime. → The more renewable energy we store, the less we rely on fossil fuels. → Battery storage adapts to different needs, from factories to family homes. Looking ahead, Power-to-X (P2X) technologies will play an important role in complementing battery storage. While BESS ensures stability in the short term, P2X can provide long-term energy storage by converting surplus renewable energy into hydrogen, synthetic fuels, or other energy carriers. This enables seasonal storage and supports industries with high energy demands, further strengthening the resilience of our energy system. ❓How do you see the role of energy storage in the transition to a climate-neutral future? Let me know in the comments below or let’s talk at Hannover Messe 2025—because the time for sustainable energy storage is now. #EnergyTransition #BatteryStorage #Sustainability #Innovation

Why are Indian solar generators selling electricity for free? India's solar capacity hits record generation of 12.3 billion units in May 2025. The result? Electricity prices are crashing toward zero during peak solar hours. Here's what's happening: 🦆 The "Duck Curve" hits India Midday solar output peaks while demand drops 30% Rajasthan's 18 GW solar capacity could only export 5% of midday power in May 2025 (down from 12% in 2024) 🌍 Global parallels everywhere: Germany: 475 hours of negative pricing in 2024 Australia: 24-26% of hours with negative prices California: 13% negative pricing hours in 2024 🔋 The obvious fix? Battery Storage. The problem? Economics. India had just 220 MWh of battery storage as of March 2024 - practically nothing for thousands of MW of daily surplus. Battery costs fell to $120/kWh, but upfront investments remain massive. 🎯 Why this matters beyond today's grid: As we scale toward 100% renewable energy globally, the battery storage constraint becomes the ultimate bottleneck. Without solving energy storage economics, the renewable transition hits a ceiling - no matter how cheap solar panels become. ⚡ Policy experiments underway: ✅ Time-of-day pricing trials in few states ✅ Massive transmission projects to move surplus between states ❌ Progress remains slow due to regulatory hurdles and costs The irony is perfect: solar has become so successful that we have too much cheap, clean electricity. As India targets 500 GW renewables by 2030 (requiring 40 GW annual solar additions), solving the "abundance problem" becomes critical. Sometimes success creates new challenges. 🔋 *** At Opten Power, we help clients procure clean energy and deploy capital in green assets. #RenewableEnergy #Solar #India #EnergyTransition #CleanTech

Going into RE+, always excited to see the latest Marketplace Report from EnergySage. Solar installations that were driven from referrals and were cash pay were able to maintain pricing that was close to the record-low median price of $2.48 per watt in H1 2025. We need to do much more of this and drive this to sub-$2/W, already achieved in Texas/Florida. Folks are seeing strong demand for cash sales through the end of the year using 25D while the TPO players are positioning themselves using 48E financing post 12/31/2025. "92% of contractors expected the loss of the federal solar tax credit to harm their business, while 70% anticipated negative impacts from potential equipment tariffs. With 36% already reporting reduced profitability from higher interest rates, 84% citing higher labor rates in the past year, and 79% heavily dependent on solar-related revenue, many installers must adapt their business models to prepare for the post-tax credit environment." https://lnkd.in/eGAVUCEH

It’s increasingly clear that bold climate action is the smartest business choice. Climate impacts are already hitting every part of supply chains, from sources of materials, to how products are transported and where they are sold. Companies risk seeing 7% carved off corporate earnings annually by 2035 due to climate impacts.   But there’s also good news – the global clean energy transition is booming, set to hit US$2 trillion this year alone, even if we need to see its huge benefits shared far more widely.   Setting ambitious goals to decarbonize and achieving them, and investing in adaptation and resilience, makes total business sense.   According to a recent report by the World Economic Forum: 👉 Industries can reduce 10-60% of their emissions at no or limited additional cost. 👉 Companies can expect up to $19 in benefits for every $1 invested in adaptation and resilience.   Climate-proofing is no longer optional for businesses. It is a necessity. And a massive opportunity too good to miss.

The Strait of Hormuz crisis has laid bare the fragility of global energy dependence. With oil flows disrupted and freight costs soaring, India’s clean energy transition emerges as the backbone of economic resilience. Even as war slows infrastructure delivery, it accelerates India’s strategic imperative to scale renewables.   Clean energy is a national security priority, anchored in three decisive levers.   1. Financing as Structural Reinforcement: The Union Budget’s 30% increase in the Ministry of New and Renewable Energy (MNRE) allocation, to ₹32,915 crore, is the anchor of India’s energy financing strategy. This sovereign clarity channels capital into solar manufacturing, rooftop deployment under PM Surya Ghar, and storage integration. Financial institutions are reinforcing this momentum: the Asian Development Bank (ADB)’s $1.2 billion loan adds scale to the government’s push. Its $331 million deal with ReNew last year in Andhra Pradesh underscores global confidence in India’s ability to deliver amid Asia’s energy vulnerability.   2. Storage as National Security: Storage has moved to the centre of grid resilience. Capacity is set to expand tenfold—from 507 MWh to 5 GWh in 2026—even as commodity price shocks threaten economics. This can set the ball rolling on diversification: pumped hydro as a hedge, and high fossil fuel prices tilting competitiveness toward green hydrogen.   3. Manufacturing as Industrial Strength: Supply chain delays and freight costs highlight the risks of import dependence. India’s financing push into domestic solar manufacturing reduces vulnerability. Inventory buffers provide near-term protection, while localisation ensures the 500 GW renewable target by 2030 is treated as a floor, not a ceiling.   The crisis in West Asia may slow delivery, but it paradoxically accelerates India’s strategic imperative for renewables. Clean energy is no longer ambition—it is resilience and economic strength. #EnergySecurity #ReNewTheFuture
