As missiles fly and oil traders panic, one thing is becoming brutally clear: a world powered by more renewables is a world less exposed to political violence, fuel blackmail by Iran and Saudi Aramco, and petro-instability that have long haunted the Middle East.

According to the International Renewable Energy Agency (IRENA), a UN-like energy body based in Abu Dhabi, the world added a record 692 gigawatts (GW) of renewable power capacity in 2025, bringing the global total to 5,149 GW.

Renewables made up 85.6% of all new power capacity added worldwide, while fossil fuel and other non-renewable additions continued to shrink in relative importance. That matters far beyond climate, I believe.

When countries generate more of their own electricity from solar, wind, hydro and bioenergy, they become less vulnerable to oil and gas chokepoints, tanker wars, Red Sea Houthi pirates, Iranian mullahs, price spikes, and the geopolitics of regimes and armed movements that have historically benefited from fossil fuel dependence. Renewables do not solve extremism on their own, but they do weaken the leverage of fuel-dependent systems that have helped finance instability across the region.

“In the midst of uncertain time, renewable energy remains consistent and steadfast in its expansion,” said Francesco La Camera, IRENA’s Director-General. “A more decentralised energy system, with a growing share of renewables and more market players, is structurally more resilient.”

IRENA, headquartered in Abu Dhabi, is the world’s leading intergovernmental agency for the renewable energy transition. It has 171 members and additional countries in accession, and serves as a technical and policy hub for governments trying to decarbonize while improving energy security. Abu Dhabi is its permanent headquarters.

The biggest gains in 2025 came from solar power, which added 511 GW, followed by wind at 159 GW. Together, those two technologies accounted for 96.8% of all new renewable additions globally.

Asia dominated, contributing 74.2% of all new renewable capacity, with 513.3 GW added. China remained the giant, especially in solar, wind, and hydropower, according to IRENA. This doesn’t mean they are a green economy however, because as China grows so does its dependence on fossil fuels. They are not regulated in any way for carbon emissions and tend to do what they want while the rest of the world plants trees and trades carbon credits.

India also posted strong wind and hydro gains. In Africa, renewable capacity rose by 15.9%, its fastest jump yet, led by Ethiopia, South Africa, and Egypt. The Middle East recorded its highest annual growth too, rising 28.9%, led by Saudi Arabia. The House of Saud knows they cannot survive on oil alone in the future. They have also been investing in green hydrogen.

The map is wildly uneven. Europe now holds 934 GW in total renewable capacity, while Central America and the Caribbean remain stuck at just 21 GW. That imbalance is not just unfair; it is also dangerous. Countries with low renewable penetration remain more exposed to imported fuel shocks, debt, and fragile grids.

The world’s next focus should be obvious: grid expansion, battery storage solutions, off-grid solar, and finance for poorer countries. It is not enough to install panels in China as its economy keeps building endless factories and call it a transition.

“This not only indicates market preference but also makes a strong case for renewable energy resilience with brutal clarity,” La Camera said. And in a world where oil routes can still trigger global panic overnight, resilience is no longer a climate luxury, it is national security.

Web hosting can make or break your online presence. SiteGround has been a popular choice for years, but price increases and feature restrictions have many users looking elsewhere. Here are five hosting providers that offer comparable or better services, with GreenGeeks leading the pack.

GreenGeeks Takes the Top Spot

GreenGeeks has earned its position as the best SiteGround alternative through a combination of fast servers, eco-friendly operations, and competitive pricing. Independent tests from 2025 show GreenGeeks loading WordPress sites in 1 to 2 seconds, even under stress from 50 or more concurrent users.

The company runs on LiteSpeed servers with built-in LSCache technology. This setup consistently delivers lower time-to-first-byte measurements than SiteGround’s Google Cloud infrastructure. While SiteGround can load static pages in 0.3 seconds, its real-world WordPress performance ranges from 1.4 to 2.5 seconds on entry-level plans.

GreenGeeks offers unlimited storage, bandwidth, and websites on all plans. SiteGround limits these based on your chosen tier. The entry-level GreenGeeks plan starts at $2.95 per month and renews at $10.95. SiteGround’s comparable plan costs $2.99 initially but jumps to $16.99 on renewal.

Environmental Leadership Sets GreenGeeks Apart

GreenGeeks purchases renewable energy certificates for 300% of the power it uses. This means for every unit of electricity the company consumes, it funds three units of wind or solar power generation. SiteGround makes no environmental offset claims beyond the efficiency of its Google Cloud platform.

The environmental certifications are verified and audited. Each hosting account directly supports certified renewable energy projects. This commitment has earned GreenGeeks industry recognition for sustainability leadership in 2025.

The latest Renewable Energy Statistics 2025 report from the International Renewable Energy Agency (IRENA) based in the United Arab Emirates reveals a widening global divide in the renewable energy transition. While Asia added the lion’s share of new renewable energy capacity in 2024—an astounding 71%—regions such as Africa, Central America, and the Caribbean collectively contributed only 2.8% to global growth.

Africa, in particular, expanded its renewables capacity by just 7.2%, despite its vast untapped resources and pressing need for energy access.

This imbalance poses a serious challenge to the global goal of tripling renewable capacity by 2030, as agreed at COP28. If the current growth trajectory continues, the world will reach only 10.3 terawatts (TW) of installed renewables by 2030—falling 0.9 TW short of the 11.2 TW target. To stay on course, annual capacity must grow by at least 16.6% over the next five years.

Francesco La Camera, Director-General of IRENA, underscores the urgency of closing this investment and infrastructure gap. “The renewable energy boom is transforming global energy markets, driving economies and creating vast investment opportunities,” La Camera said. “However, the growing regional divide highlights that not everyone is benefiting equally from this transition.”

Indeed, countries that have succeeded in attracting renewable investment—particularly in Asia and parts of Europe—are now reaping broader economic rewards, including increased energy security, job creation, and industrial growth.

The 2024 data also highlights the overwhelming dominance of solar and wind energy, which accounted for 97.5% of all net renewables additions. Solar energy alone contributed 453 GW, reinforcing its position as the most cost-competitive and rapidly scalable clean energy source on the planet. Wind followed with 114 GW.

With renewables now representing 46.2% of global installed power capacity—nearly equal to fossil fuels at 47.3%—the economic and environmental case for continued investment is stronger than ever. Renewable electricity generation grew by 5.6% in 2023 compared to 2022, reaching 8,928 terawatt-hours, while non-renewable generation grew by only 1.2%.

Still, the benefits of this energy revolution are not evenly shared. As La Camera notes, “Bridging the divide and closing the investment gap between countries and regions is critical. It requires targeted policies, international financing, and partnerships that unlock capital and technology where they are needed most.”

UN Climate Change Executive Secretary Simon Stiell echoed this call to action: “To deliver on the global agreement at COP28 to triple renewables by 2030, we need to move much further and faster, and make more progress on the key enablers for vulnerable developing countries. The investments required will pay huge dividends—cutting emissions, driving economic growth, creating jobs, and supporting affordable, secure energy for all.”

The message is clear: the green energy future is well underway, but unless more inclusive policies and financing mechanisms are put in place, the clean energy divide could become the defining inequity of the 21st century.

Meet Yosef Abramowitz, CEO of Gigawatt Global, bringing clean solar energy to millions around the world

Yosef Abramowitz, known also as Kaptain Sunshine, is an American-Israeli solar activist and developer.  As a child, Abramowitz lived in Israel. However, during a brief couple of years back in America during the Yom Kippur War, Abramovitz faced confusion. Outside his Massachusetts window sat a gas station with a line wrapping around the block. The long line was a result of the conflict in the Middle East and the 1973 Arab Oil Embargo. Abramowitz’s confusion stemmed from this: how could America and the rest of the world rely on an unrenewable energy source as volatile as this? After this moment, Yosef sought change. While Jimmy Carter was installing solar panels in the White House, Abramowitz was working on early science fair solar projects. Eventually, his work and passion for Israel led him back to the country where he would do his most impactful work yet.

In 2006, after arriving at Kibbutz Ketura to attend the Arava Institute for Environmental Studies, Yosef Abramowitz stepped out of his van with the last rays of the golden sun shining down on the scorching Arava Desert. In the dying sunset, he found his light. Abramowitz and his associates founded the Arava solar fields. During its 2010 inception, students, researchers, and other individuals from over 58 countries came to learn. Out of this work came Gigawatt Global and the company’s mission of being a “…multinational renewable energy company focused on the development and management of utility-scale solar fields in emerging markets.”

The goal was clear. Bring climate justice to the communities that need it most.

Gigawatt Global and its CEO, Abramowitz, have brought power to some of the most impoverished and energy-deficient countries in the world, with Rwanda, Nigeria, and South Sudan being just a few examples of the hard-to-reach places where they work.

Through his work, Abramowitz has had a significant impact. In Burundi, one of the world’s poorest countries, Abramowitz and his team successfully brought solar energy to half a million people. Another example of the extent of his beneficial humanitarian work comes from Rwanda, where he brought power to the Agahozo-Shalom Youth Village. The village is home to orphans of the Rwandan genocide. “It’s both a mitzvah and a business,” Abramowitz says.

So, how does he do it? Abramowitz used to get support from the American Government. However, a majority of his funding comes from Blended Finance. This means that his monetary support comes from both public and private donors and investors. Abramowitz is always seeking international support, as well as funding from financial institutions such as the World Bank.

Abramowitz employs what he calls the Quadruple Bottom Line Impact Platform when bringing solar energy to countries with limited resources and infrastructure. While not the primary driver, each project must provide returns for investors. While these returns may not turn a massive profit, projects must ensure financial viability. Second, every project contributes to climate mitigation. Using solar energy not only provides energy to those in need but also reduces carbon emissions and air pollution associated with previously used, dirty, combustible fuels. Third is the humanitarian and social impact that a project will provide for its community. Finally, solar development can strengthen relationships between countries. It can build trust in fragile states and open doors for diplomacy.

Why does he do it? It may be hard to understand why someone would want to take on the challenges that Abramowitz does. He is not taking the easy projects. He is not developing solar fields in Europe, the Americas, or other developed nations. Abramowitz is going places that nobody else is going to. Not because of money, even though it is there, but because of his values. Abramowitz values Tikkun Olam, the act of repairing the world. Through his solar projects, he is helping the most vulnerable people on Earth, doing his part to make a difference. He emphasized the privilege that Western countries have. He also realizes that there are already help and resources available for these places and that there are numerous opportunities to do good outside of the established market.

It is not all sunshine for Kaptain Sunshine. Many of the places he is going are politically and infrastructurally fragile. This means that Abramowitz and his associates need to remain steadfast in their morals. It is essential to Abramowitz that he bring power to those in need. However, he will walk away if the corruption and values of those he is helping cannot align with his values.

However, Abramowitz strongly emphasized that the people he meets in Africa and around the world —the ordinary people —are the reason he does what he does. When the going gets tough, he remembers who he is working for. Not for a nation, government, or political party. For the people.

There is a significant intersectionality at play in Abramowitz’s work. He described how bringing power to a country uplifts it in many other ways. Food storage, communication, and information are just a few benefits that come with energy. With these benefits, many are given a chance to succeed. In places where terror runs rampant, energy projects are run through communities to prevent them from becoming corrupted.

Yosef Abramowitz is a visionary, humanitarian, and innovator. Not only did Abramowitz help facilitate Israel’s transition to become more environmentally friendly. He helped make the world not only a cleaner place by introducing solar energy, but also a better place by bringing it to those who need it most. Following Theodor Herzl’s idea that “If you will it, it is no dream,” Abramowitz continues his dream of bringing energy to all.

As tensions over water intensify across Iraq and the wider Middle East, the 5th Baghdad International Water Conference has cast a timely spotlight on the country’s fragile water future—and its ancient hydrological past.

Held in the heart of Mesopotamia—where early civilizations once mastered the art of water management—the conference drew regional experts and leaders to Baghdad to confront a crisis that’s becoming more urgent by the year: water scarcity. With rivers running dry and modern agricultural systems straining under the pressure, Iraq finds itself at a crossroads between its hydraulic heritage and an increasingly parched present.

The land between the Tigris and Euphrates was once a wellspring of invention. Thousands of years before modern irrigation, the Sumerians, Akkadians, Babylonians, and Assyrians carved canals, engineered flood basins, and developed qanat systems—ingenious underground channels that carried water from mountain springs to distant farms.

These systems weren’t just technical achievements; they were the lifeblood of cities, temples, and trade. Water determined everything—from the rise of empires to the poetry etched into clay tablets.

But today, the once-mighty rivers that sustained those ancient cultures are shrinking. Dams upstream, salinization, climate shocks, and mismanagement have left Iraq’s water infrastructure overburdened and outdated. Agriculture now consumes over 90% of Iraq’s water, yet crop yields are falling. Some estimates suggest that without reform, wheat and barley yields could drop by half by 2050.

How a qanat works

These aren’t just numbers. Iraq’s rural communities—many of whom still rely on traditional farming—are already being uprooted by water shortages. Marshlands, once teeming with biodiversity and cultural life, are evaporating. The disappearance of water from ancestral lands threatens to sever ties to history, religion, and identity.

This has ignited conflict—not just between nations sharing river systems, but within Iraq itself. Disputes over water rights are rising, and in some areas, violence has already erupted. A younger generation, particularly women and smallholder farmers, are being left with few options: adapt or leave.

Despite the severity of the situation, Iraq isn’t without solutions. The country is rediscovering the value of its past while cautiously embracing modern technologies. Sometimes, like in Afghanistan the outcome can be dubious. Opium farmers now use solar powered water pumps to cultivate poppies.

Remote sensing tools, such as those used in the WaPOR programme, are helping farmers monitor water use and optimize irrigation. Solar-powered systems, being piloted in neighboring Egypt and Tunisia, offer hope for regions where diesel pumps are no longer viable. Community-led water user associations—reminiscent of ancient collective water governance structures—are being revived to restore trust and accountability.

If you picture an eco-village, you might imagine a simple dwelling with permaculture gardens and a very slow, rural pace of life. While often true, this rustic image undermines the technology that is increasingly being used to achieve their sustainability – technology that we shouldn’t be frightened of or avoid, but use to harness a greener way of life.

Energy solutions

Energy independence is a big part of eco villages. While solar panels are the visible, sung heros here, the real magic lies in integrated systems underpinning them. Smart microgrids are used to manage locally generated power from diverse mix of sources like solar, micro-hydro, or even wind. They balance loads and incorporate battery banks for storage, which reduces the reliance on external grids. 

Advanced solar integration can be expressed through Building-Integrated Photovoltaics (BIPV), in which the solar cells become part of the building fabric itself. The real MVPs, though, are the energy efficiency monitoring systems, such as smart meters and community dashboards, which can track both generation and consumption. Through finding patterns, or possibly using machine learning, it’s possible to better align the two so there’s no waste (this is even more important when many dwellings share energy).

Intelligent water management systems

Water is life, and eco-villages treat it as such through age-old conservation and reuse techniques. Rainwater harvesting isn’t just barrels, it means having integrated roof catchments feeding into systems with first-flush diverters that automatically discard the initial, most contaminated runoff. Water then passes through staged filtration, like sediment traps, then by sand or gravel, before collection in large cisterns. Again, IoT sensors are often used to help determine and notify of capacity and cleanliness levels.

For accessing this water, particularly for irrigation, choose a submersible pump for its efficiency – this can quickly transfer water in a reliable way. Further along the cycle might be constructed wetlands, which are carefully designed shallow beds. They’re planted with aquatic vegetation and use natural microbial processes within their gravel and sand substrates to purify greywater (sometimes even pre-treated blackwater), making it safe for irrigation with minimal energy input.

Waste not, want not

“Waste” is a resource that’s awaiting transformation. Composting techniques like vermicomposting (using worms) or Bokashi (fermentation) help process organic matter into rich soil amendments. Of course, these are old techniques that don’t require much technology.

However, investing in some innovative technology can open more doors to transformation, as not all transformation can be naturally captured. Some communities employ anaerobic biogas digesters, which are sealed tanks that break down food scraps and animal manure in an oxygen-free environment. This produces methane gas for cooking or heating as well as a nutrient-rich liquid fertilizer. IoT sensors, again, can track microbial activity to help boost gas yields.

Technology as the invisible foundation

Energy, water, and waste are the three flows that need to be managed by intelligent technologies. This infrastructure is frequently “unseen” because it’s designed to be integrated and harmonious with natural systems, rather than intrusive (it’s not consumption-led). Harmony between dwellings can be difficult, and this is where integrated systems can communicate. It goes to show that such communities are not anti-technology, but instead are simply selective about only using technology that benefits them and aligns with their values.

Raven reviews the e-trike from Mooncool in her off-grid forest

I was contemplating how to ready myself for old age, using the body wisely, and still attending to daily routines. Such was the state of inner asking when grace responded with the arrival of MoonCool, an e-trike. Silence is what I did not wish to disturb for me, the forest, and its creatures.

SOMBRA, a name fusing the Latin words for sun (sol) and shade (umbra), is more than a temporary pavilion—it’s a living laboratory. Shaped like a heliodon, the structure mimics how the sun moves through the sky, providing an intuitive experience of solar patterns.

It operates without motors, electronics, or external energy. Instead, it breathes, opens, and closes using only passive physical principles. A similar shade system was developed by Dutch engineers in the Gulf region — see the startup Airshade. And this group has partnered on the Venice exhibit.

Measuring just 30 square meters, SOMBRA is a compact marvel of climate-sensitive architecture. The pavilion’s six metal ribs, angled to correspond with the solar angles of the summer and winter solstices, support triangular shading panels made of perforated MD Formatura screens by Metadecor.

These panels respond autonomously to sunlight: opening when skies are overcast to maximize views, and closing during intense sunlight to offer shade.

The core innovation lies in the Airshade system. The pavilion hides small air canisters within its ribbed frame. When sunlight heats a canister, air pressure increases, inflating a miniature airbag. Inspired by soft robotics, the airbag acts like a muscle, countering the spring hinge to close the shading panel. As clouds pass and temperatures drop, the air deflates and the panel reopens.

This poetic movement mimics a living organism, giving the pavilion an animated presence as it reacts to its environment—without consuming any operational energy.

As MVRDV partner Bertrand Schippan explains: “With the climate crisis accelerating, it’s clear that we need new architecture that is more in tune with the environment. SOMBRA is a demonstration of one approach among many to this philosophy: an architecture that senses its environment and reacts to it in much the same way that plants do.”

SOMBRA’s narrative is layered in symbolism. Its circular floor plate is engraved with the polar sun path chart used to guide its geometry. Underneath the ribs, over 200 translations of the words “sun and shade” remind visitors that the sun connects all of humanity—a shared experience cutting across cultures, geographies, and languages.

Remember 15 years ago when cargotecture was the “thing” and our resident architect blew the lid off the premise of upcycled ship containers being safe and eco friendly? There is such a lag on the concepts of design and the time it takes to make a dream reality –- meaning we are still seeing new cargotecture concepts brought to life, even though, maybe, it wasn’t such a great idea in hot countries. And some of the containers contained hazardous materials that should not be in contact with people. But what about decommissioned wind turbines?

Time for a new eco obsession? How about living in a wind turbine blade that has fulfilled its purpose of collecting energy? A new report from the US Department of Energy, the DOE, outlines recommendations that could increase the recycling and reuse of decommissioned wind energy equipment and materials to create a more circular economy and sustainable supply chain.

The research reveals that existing US infrastructure could process 90% of the mass of decommissioned wind turbines. However, the remaining 10% will need new strategies and innovative recycling methods to achieve a more sustainable wind energy industry. This research will help guide over $20 million in investments previously announced from the Bipartisan Infrastructure Law to advance technologies that address this gap.

Looking for recycling innovators and funding them too

“The US already has the ability to recycle most wind turbine materials, so achieving a fully sustainable domestic wind energy industry is well within reach,” said Jeff Marootian, principal deputy assistant secretary for the Office of Energy Efficiency and Renewable Energy. “Innovation is key to closing the loop, and this research will help guide national investments and strategies aimed at advancing technologies that can solve the remaining challenges and provide more affordable, equitable, and accessible clean energy options to the American people.”

The new Recycling Wind Energy Systems in the United States report provides an assessment of research, development, and demonstration (RD&D) needs and gaps in existing wind energy-related supply chains to support the transition to a more sustainable and circular US wind energy industry. This is research that could easily be applied to other wind energy markets.

A team of researchers, led by the National Renewable Energy Laboratory with support from Oak Ridge National Laboratory and Sandia National Laboratories, developed the report. The effective reuse and recycling of wind system components, parts, and materials will rely on a combination of measures, including:

• Improved end-of-life decommissioning collection and scrap sorting practices.
• Strategic siting of recycling facilities.
• Expanded and improved recovery and recycling infrastructure.
• Substitution of hard-to-recycle and critical materials with more easily separable and affordable materials, improved component designs and manufacturing techniques, or the development of modular system components.
• Optimized properties of recovered materials for second-life applications.
• Greater access to wind energy waste streams and the equipment required to disassemble wind energy components.

Towers, foundations, and steel-based subcomponents in drivetrains offer the greatest potential currently to be successfully recycled, whereas blades, generators, and nacelle covers are likely to prove more difficult. Unless you want to live inside a wind turbine nacelle?

A nacelle is a streamlined container for aircraft parts such as engines, fuel or equipment. You can see one above.

Recovering critical materials and alloying elements from generators and power electronics, such as nickel, cobalt, and zinc, will be crucial in establishing a circular economy for wind systems.

Short-term strategies for decommissioning include promoting blade production using more easily recyclable thermoplastic resins and reusing these resins in cement production, they write.

Thermoplastic-based blade recycling technologies, such as pyrolysis and chemical dissolution, could be viable medium- and long-term options. Other medium- and long-term solutions include high-yield techniques for separating compounds found in power electronics and hybrid methods for recycling permanent magnets.

Regional factors—such as material demand, disposal fees, transportation distances, and an available skilled workforce—will play vital roles in ensuring the success and cost-competitiveness of recycling wind energy components.

Funding for Wind Turbine Recycling

Research used to compile this report will be used to guide the development of the Wind Energy Recycling Research, Development, and Demonstration program funded by the Bipartisan Infrastructure Law.

DOE recently announced an investment of $20 million to improve the recycling of wind energy technologies. This effort, which focuses on enabling sustainable wind turbine components, enabling wind turbine material recycling and reuse processes, and qualifying recycled and recyclable material, will help increase the sustainability of wind energy materials and bolster the domestic supply chain. If you have a recycling solution, apply!

Applications are due on Feb. 11, 2025. You could make a new company out of a bold idea.

But let’s look at a consumer product for inspiration. Living in a wind turbine? As of today that’s possible.

The energy company Vattenfall and design studio Superuse converted a nacelle, the top part of a wind turbine, into a tiny house. This nacelle is 4 yards wide, ten yards long and three yards high and comes from a turbine that stood in Austria for 20 years.

With the tiny house, Vattenfall demonstrates how materials can be reused in innovative ways. The tiny house was on display during Dutch Design Week from 19 to 27 October.

Jos de Krieger, partner Superuse and Blade-Made: “At least ten thousand of this generation of nacelles are available, spread around the world. Most of them have yet to be decommissioned. This offers perspective and a challenge for owners and decommissioners. If such a complex structure as a house is possible, then numerous simpler solutions are also feasible and scalable.”

In collaboration with Reliving, the tiny house was furnished with sustainably produced and second-hand furniture, including a table made of circuform that incorporates material from a recycled wind turbine blade. The electrical installation was installed by Vattenfall subsidiary Feenstra.

The nacelle used for construction was taken from a V80 2MW turbine built at the Austrian Gols wind farm in 2005. During 20 years of faithful service, the turbine produced 73GWh of electricity, enough to power more than 29-thousand households for a year. The nacelle once stood at a height of 100 metres.

Dutch company Business in Wind decommissioned the wind farm and made the nacelle available for this project.
