Rooftop solar should pay for itself

AWS Renewable Energy Projects deliver new wind power for AWS data centers in Ireland, Sweden, and the US, adding 229 MW and 670,000 MWh annually, supporting 100% renewable targets and global cloud sustainability.

Key Points

AWS projects add wind power in Ireland, Sweden, and the US to supply clean energy for AWS data centers.

✅ 229 MW new wind capacity; 670,000 MWh annual generation

✅ Sites: Donegal (IE), Backhammar (SE), Tehachapi (US)

✅ Advances 100% renewable goal for global AWS infrastructure

 Amazon has announced three new clean energy projects as part of its long-term goal to power all Amazon Web Services (AWS) global infrastructure with renewable energy. These projects – one in Ireland, one in Sweden, and one in the United States – will deliver wind-generated energy that will total over 229 megawatts (MW) of power, with expected generation of over 670,000 megawatt hours (MWh) of renewable energy annually. The new projects are part of AWS’s long-term commitment to achieve 100 percent renewable energy for its global infrastructure. In 2018, AWS exceeded 50 percent renewable energy for its global infrastructure.

Once complete, these projects, combined with AWS’s previous nine renewable energy projects, reflect how renewable power developers benefit from diversified sources and are expected to generate more than 2,700,000 MWh of renewable energy annually – equivalent to the annual electricity consumption of over 262,000 US homes, which is approximately the size of the city of Nashville, Tennessee.

“Each of these projects brings us closer to our long-term commitment to use 100 percent renewable energy to power our global AWS infrastructure,” said Peter DeSantis, Vice President of Global Infrastructure and Customer Support, Amazon Web Services. “These projects are well-positioned to serve AWS data centers in Ireland, Sweden, and the US. We expect more projects in 2019 as we continue toward our goal of powering all AWS global infrastructure with renewable energy.”

Amazon has committed to buying the energy from a new wind project in Ireland, a 91.2 MW wind farm in Donegal. The Donegal wind farm project is expected to deliver clean energy no later than the end of 2021.

“AWS’s investment in renewable projects in Ireland illustrates their continued commitment to adding clean energy to the grid and it will make a positive contribution to Ireland’s renewable energy goals,” said Leo Varadkar, An Taoiseach of Ireland. “As a significant employer in Ireland, it is very encouraging to see Amazon taking a lead on this issue. We look forward to continuing to work with Amazon as we strive to make Ireland a leader on renewable energy.”

Amazon will also purchase 91 MW of power from a new wind farm in Bäckhammar, Sweden, which is expected to deliver renewable energy by the end of 2020.

“Sweden has long been known for ambitious renewable energy goals, and this new wind farm showcases both our country’s leadership and AWS’s commitment to renewable energy,” said Anders Ygeman, Sweden’s Minister for Energy and Digital Development. “This is a significant step in Sweden’s renewable energy production as we work toward our target of 100 percent renewable energy by 2040.”

California leads the United States in renewable electricity generation from non-hydroelectric sources, as US solar and wind growth accelerates, and the state’s Tehachapi Mountains, where AWS’s wind farm will be located, contain some of the largest wind farms in the country. The wind farm project in Tehachapi is expected to bring up to 47 MW of new renewable energy capacity by the end of 2020.

“This announcement from AWS is great news, not just for California, but for the entire country, as it reaffirms our role as a leader in renewable energy and allows us to take an important step forward on deploying the clean energy we need to respond to climate change,” said California State Senator Jerry Hill, San Mateo and Santa Clara Counties, a member of the Senate Standing Committee on Energy, Utilities and Communications.

Beyond the sustainability initiatives focused on powering the AWS global infrastructure, Amazon recently announced Shipment Zero, which is Amazon’s vision to make all Amazon shipments net zero carbon, with 50 percent of all shipments net zero by 2030. Additional sustainability programs across the company include Amazon Wind Farm Texas, which adds more than 1 million MWh of clean energy each year, alongside Amazon Wind Farm US East that is now fully operational, demonstrating scale. In total, Amazon has enabled 53 wind and solar projects worldwide, which produce more than 1,016 MW and are expected to deliver over 3,075,636 million MWh of energy annually, while peers like Arvato's solar power plant underscore broader momentum across the industry. These projects support hundreds of jobs, while providing tens of millions of dollars of investment in local communities, with Iowa wind power offering a strong example. Amazon has also set a goal to host solar energy systems at 50 fulfillment centers by 2020. This deployment of rooftop solar systems, aided by cheap batteries that enhance storage, is part of a long-term initiative that will start in North America and spread across the globe. Amazon also implemented the District Energy Project that uses recycled energy for heating Amazon offices in Seattle.

Newfoundland and Labrador electricity rate hike examines a proposed 18.6% increase under the PUB's Rate Stabilization Plan, driven by oil prices at Holyrood, with Consumer Advocate concerns over rate shock and use of RSP balances.

Key Points

A proposed 18.6% July 2017 increase under the RSP, driven by oil prices, now under PUB review for potential mitigation.

✅ PUB flags potential rate shock from proposed adjustment

✅ RSP balances cited to offset increases without depleting fund

✅ Oil-fired Holyrood volatility drives fuel cost uncertainty

How much of a rate hike is reasonable for users of electricity in Newfoundland and Labrador?

That's a question before the Public Utilities Board (PUB) as it examines an application by Newfoundland and Labrador Hydro, which could see consumers pay up to 18.6 per cent more as of July 1, reflecting regional pressures seen in Nova Scotia, where regulators approved a 14% rate hike earlier this year.

"The estimated rate increase for July 2017 is such a significant increase that it may be argued that it would cause rate shock," said the PUB, asking the company to revise its application.

NL Hydro said the price adjustment is part of what happens every year through the Rate Stabilization Plan (RSP), which is used to offset the ups and downs of oil prices.

"The cost of fuel is volatile and as long as we rely on oil-fired generation at Holyrood, customers will continue to be impacted by this electricity price uncertainty," said the company in a statement to CBC News.

It noted that customers received a break from RSP adjustments in 2015 and 2016, even as costs from the Muskrat Falls project begin to be reflected.

The PUB noted that under the rate stabilization plan, prices have gone up or down by about 10 per cent in the past.

The regulatory board said the impact of the latest request would be a 27.6 per cent hike to Newfoundland Power, with "an estimated average end customer impact of 18.6 per cent."

Hydro's estimates are based on an average price for oil of $81.40 per barrel from July 2017 to June 2018, according to the PUB.

'Unacceptable' burden: Consumer Advocate

"To burden ratepayers with an 18 per cent rate increase is unacceptable," said Consumer Advocate Dennis Browne, echoing pushback in Nova Scotia, where the premier urged regulators to reject a 14% hike at the time.

Browne is arguing that there is money in the RSP to reduce the proposed increase, including the possibility of a lump-sum bill credit for customers.

"These ratepayer balances — which, according to NL Power, totals $77.4 million — are not the property of Hydro," he wrote in a letter to the PUB.

"No utility has the right to squirrel away ratepayers' money to be used by that utility for some future purpose. The Board has jurisdiction over those balances," Browne said.

Browne also wants the RSP overhauled so that it can be applied to price fluctuations every quarter, as opposed to annually.

Hydro has expressed concern that depleting the rate stabilization fund would lead to other, more significant, rate increases in the future.

It said several alternatives to mitigate high rates have been provided to the PUB, which has final say, similar to how Manitoba Hydro scaled back a planned increase in the next year.

Wall Street backs Rick Perry’s $19 billion nuclear-powered data center venture, Fermi America, combining nuclear energy, AI infrastructure, and data centers to meet soaring electricity demand and attract major investors betting on America’s clean energy technology future.

What is "Wall Street Backs Rick Perry’s $19 Billion Nuclear-Powered Data Center Venture”?

Wall Street is backing Rick Perry’s $19 billion nuclear-powered data center venture because it combines the explosive growth of AI with the promise of clean, reliable nuclear energy.

✅ Addresses AI’s massive power demands with nuclear generation

✅ Positions Fermi America as a pioneer in energy-tech convergence

✅ Reflects investor confidence in long-term clean energy solutions

Former Texas Governor and U.S. Energy Secretary Rick Perry has returned to the energy spotlight, this time leading a bold experiment at the intersection of nuclear power and artificial intelligence. His startup, Fermi America, headquartered in Amarillo, Texas, went public this week with an initial valuation of $19 billion after its shares surged 55 percent above the opening price on the first day of trading.

The company aims to tackle one of the most pressing challenges in modern technology: the staggering energy demand of AI data centers. “Artificial intelligence, which is getting more and more embedded in all parts of our lives, the servers that host the data for artificial intelligence are stored in these massive warehouses called data centers,” said Houston Chronicle energy reporter Claire Hao. “And data centers use a ton of electricity.”

Fermi America’s plan, Hao explained, is as ambitious as it is unconventional. Fermi America has a proposal to build what it claims will be the world’s largest data center, powered by what it asserts will be the country’s largest nuclear complex. So very ambitious plans.”

According to the company’s roadmap, Fermi aims to bring its first mega reactor online by 2032, followed by three additional large reactors. In the meantime, the firm intends to integrate natural gas and solar energy by the end of next year to support early-stage operations.

While much of the energy sector’s attention has turned toward small modular reactors, Fermi’s approach focuses on traditional large-scale nuclear technology. “What Fermi is talking about building are large traditional reactors,” Hao said. “These very large traditional reactors are a tried and true technology. But the nuclear industry has a history of taking a very long time to build them, and they are also very expensive to build.” She noted that the most recent example, completed in 2023 by a Georgia utility, came in $17 billion over budget and several years late.

To mitigate such risks, Fermi has recruited specialists with international experience. “They’ve hired folks that have successfully built these projects in China and in other countries where it has been a lot smoother to build these,” Hao said. “Fermi wants to try to make it a quicker process.”

Perry’s involvement lends both visibility and controversy. In addition to co-founding the company, Griffin Perry, his son, plays a role in its management. The firm has hinted that it might even name reactors after former President Donald Trump, under whom Perry served as Secretary of Energy. Perry has framed the project as part of a national effort to regain technological ground. “He really wants to help the U.S. catch up to countries like China when it comes to delivering nuclear power for the AI race,” Hao explained. “He says we’re already behind.”

Despite the fanfare, Fermi America is still a fledgling enterprise. Founded in January and announced publicly in June, the company reported a $6.4 million loss in the first half of the year and has yet to generate any revenue. Still, its IPO exceeded expectations, opening at $21 a share and closing above $32 on the first day.

“I think that just shows there’s a lot of hype on Wall Street around artificial intelligence-related ventures,” Hao said. “Fermi, in the four months since it announced itself as a company, has found a lot of different ways to grab people’s attention.”

For now, the project represents both a technological gamble and a test of investor faith — a fusion of nuclear ambition and AI optimism that has Wall Street watching closely.

Solar-Wind-Water West Africa integrates hydropower with solar and wind to boost grid flexibility, clean electricity, and decarbonization, leveraging the West African Power Pool and climate data modeling reported in Nature Sustainability.

Key Points

A strategy using hydropower to balance solar and wind, enabling reliable, low-carbon electricity across West Africa.

✅ Hydropower dispatch covers solar and wind shortfalls.

✅ Regional interconnection via West African Power Pool.

✅ Cuts CO2 versus gas while limiting new dam projects.

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, amid IEA investment needs for universal access, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades - which many countries now want to rid themselves of."

Solar and wind power generation is increasing worldwide and becoming cheaper and cheaper. This helps to keep climate targets in sight, but also poses challenges. For instance, critics often argue that these energy sources are too unpredictable and variable to be part of a reliable electricity mix on a large scale, though combining multiple resources can enhance project performance.

"Indeed, our electricity systems will have to become much more flexible if we are to feed large amounts of solar and wind power into the grid. Flexibility is currently mostly provided by gas power plants. Unfortunately, these cause a lot of CO2 emissions," says Sebastian Sterl, energy and climate expert at Vrije Universiteit Brussel (VUB) and KU Leuven. "But in many countries, hydropower plants can be a fossil fuel-free alternative to support solar and wind energy. After all, hydropower plants can be dispatched at times when insufficient solar and wind power is available."

The research team, composed of experts from VUB, KU Leuven, the International Renewable Energy Agency (IRENA), and Climate Analytics, designed a new computer model for their study, running on detailed water, weather and climate data. They used this model to investigate how renewable power sources in West Africa could be exploited as effectively as possible for a reliable power supply, even without large-scale storage, in line with World Bank support for wind in developing countries. All this without losing sight of the environmental impact of large hydropower plants.

"This is far from trivial to calculate," says Prof. Wim Thiery, climate scientist at the VUB, who was also involved in the study. "Hydroelectric power stations in West Africa depend on the monsoon; in the dry season they run on their reserves. Both sun and wind, as well as power requirements, have their own typical hourly, daily and seasonal patterns. Solar, wind and hydropower all vary from year to year and may be impacted by climate change, including projections that wind resources shift southward in coming years. In addition, their potential is spatially very unevenly distributed."

West African Power Pool

The study demonstrates that it will be particularly important to create a "West African Power Pool", a regional interconnection of national power grids to serve as a path to universal electricity access across the region. Countries with a tropical climate, such as Ghana and the Ivory Coast, typically have a lot of potential for hydropower and quite high solar radiation, but hardly any wind. The drier and more desert-like countries, such as Senegal and Niger, hardly have any opportunities for hydropower, but receive more sunlight and more wind. The potential for reliable, clean power generation based on solar and wind power, supported by flexibly dispatched hydropower, increases by more than 30% when countries can share their potential regionally, the researchers discovered.

All measures taken together would allow roughly 60% of the current electricity demand in West Africa to be met with complementary renewable sources, despite concerns about slow greening of Africa's electricity, of which roughly half would be solar and wind power and the other half hydropower - without the need for large-scale battery or other storage plants. According to the study, within a few years, the cost of solar and wind power generation in West Africa is also expected to drop to such an extent that the proposed solar-wind-water strategies will provide cheaper electricity than gas-fired power plants, which currently still account for more than half of all electricity supply in West Africa.

Better ecological footprint

Hydropower plants can have a considerable negative impact on local ecology. In many developing countries, piles of controversial plans for new hydropower plants have been proposed. The study can help to make future investments in hydropower more sustainable. "By using existing and planned hydropower plants as optimally as possible to massively support solar and wind energy, one can at the same time make certain new dams superfluous," says Sterl. "This way two birds can be caught with one stone. Simultaneously, one avoids CO2 emissions from gas-fired power stations and the environmental impact of hydropower overexploitation."

Global relevance

The methods developed for the study are easily transferable to other regions, and the research has worldwide relevance, as shown by a US 80% study on high variable renewable shares. Sterl: "Nearly all regions with a lot of hydropower, or hydropower potential, could use it to compensate shortfalls in solar and wind power." Various European countries, with Norway at the front, have shown increased interest in recent years to deploy their hydropower to support solar and wind power in EU countries. Exporting Norwegian hydropower during times when other countries undergo solar and wind power shortfalls, the European energy transition can be advanced.

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”

US Power Grid Blackouts highlight aging infrastructure, rising outages, and declining reliability per DOE and NERC data, with weather-driven failures, cyberattack risk, and underinvestment stressing utilities, transmission lines, and modernization efforts.

Key Points

US power grid blackouts are outages caused by aging grid assets, severe weather, and cyber threats reducing reliability.

✅ DOE and NERC data show rising outage frequency and duration.

✅ Weather now drives 68-73% of major failures since 2008.

✅ Modernization, hardening, and cybersecurity investments are critical.

The United States power grid has more blackouts than any other country in the developed world, according to new data and U.S. blackout warnings that spotlight the country’s aging and unreliable electric system.

The data by the Department of Energy (DOE) and the North American Electric Reliability Corporation (NERC) shows that Americans face more power grid failures lasting at least an hour than residents of other developed nations.

And it’s getting worse.

Going back three decades, the US grid loses power 285 percent more often than it did in 1984, when record keeping began, International Business Times reported. The power outages cost businesses in the United States as much as $150 billion per year, according to the Department of Energy.

Customers in Japan lose power for an average of 4 minutes per year, as compared to customers in the US upper Midwest (92 minutes) and upper Northwest (214), University of Minnesota Professor Massoud Amin told the Times. Amin is director of the Technological Leadership Institute at the school.

The grid is becoming less dependable each year, he said.

“Each one of these blackouts costs tens of hundreds of millions, up to billions, of dollars in economic losses per event,” Amin said. “… We used to have two to five major weather events per year [that knocked out power], from the ‘50s to the ‘80s. Between 2008 and 2012, major outages caused by weather, reflecting extreme weather trends, increased to 70 to 130 outages per year. Weather used to account for about 17 to 21 percent of all root causes. Now, in the last five years, it’s accounting for 68 to 73 percent of all major outages.”

As previously reported by Off The Grid News, the power grid received a “D+” grade on its power grid report card from the American Society of Civil Engineers (ASCE) in 2013. The power grid grade card rating means the energy infrastructure is in “poor to fair condition and mostly below standard, with many elements approaching the end of their service life.” It further means a “large portion of the system exhibits significant deterioration” with a “strong risk of failure.”

“America relies on an aging electrical grid and pipeline distribution systems, some of which originated in the 1880s,” the 2013 ASCE report read. “Investment in power transmission has increased since 2005, but ongoing permitting issues, weather events, and limited maintenance have contributed to an increasing number of failures and power interruptions.”

As The Times noted, the US power grid as it exists today was built shortly after World War II, with the design dating back to Thomas Edison. While Edison was a genius, he and his contemporaries could not have envisioned all the strains the modern world would place upon the grid and the multitude of tech gadgets many Americans treat as an extension of their body. While the drain on the grid has advanced substantially, the infrastructure itself has not.

There are approximately 5 million miles of electrical transmission lines throughout the United States, and thousands of power generating plants dot the landscape. The electrical grid is managed by a group of 3,300 different utilities and serve about 150 million customers, The Times said. The entire power grid system is currently valued at $876 billion.

Many believe the grid is vulnerable to an attack on substations and other threats.

Former Department of Homeland Security Secretary Janet Napolitano once said that a power grid cyber attack is a matter of “when” not “if,” as Russians hacked utilities incidents have shown.
