Solar Appreciation Day 2022: Here’re Some Unique Use of Solar Technologies Worldwide to Combat Energy Crisis
India’s budget for FY2022-23 clearly highlights the country’s priority to double down for ‘green’ and renewable energy, particularly solar, to combat climate change and meet the emission reduction targets set for 2030.
Moreover, as the Ukraine-Russia war continues, coal and natural gas prices are surging sharply across the globe. With the soaring power bills, several European and Asian countries are seeking alternatives to Russian supplies. And using technologies based on solar energy is a comparative quick fix to the energy crisis.
Meanwhile, Solar Appreciation Day 2022 is here, which is celebrated globally on every second Friday of March. The day has become all the more significant amid the ongoing climate and energy crisis. On this day, here are some unique solar technologies that demonstrate the immense potential of solar technologies to address the needs of the modern world.
Solar trolley invented by a farmer from Haryana
Pradeep Kumar, a farmer from Haryana, has built a mobile solar plant with panels mounted on a trolley that can be moved on demand. The trolley is custom made as per the user’s requirements.
In an interview with The Better India, Pradeep said, “the devices come in two sizes and carry solar panels which provide electricity of 2 HP and 10 HP. The trolley can also be mounted to the back of a tractor and has sturdy wheels that allow it to move over uneven surfaces.”
The cost-effective technology has benefitted over 2000 farmers so far.
Bihar’s floating solar power plant
The Mithila region in North Bihar is called the ‘Land of Ponds’ and is taking complete advantage of its gift. A floating solar plant is set to be commissioned in the region, consisting of 4,004 solar modules. Each module lodged in a pond can generate 505-megawatt peak (MWp) electricity and nearly 2 MW of green and clean energy. The plant can supply electricity to 10,000 people in the state.
The main benefit of a floating solar power plant is that the water cools the solar panels, ensuring their efficiency when temperatures rise, resulting in increased power generation. It also minimises evoporation of freshwater and aids fishery.
This innovation has hit two birds with one stone: producing green energy from solar panels and promoting fish farming underwater.
South Korea’s solar shade
In South Korea, a highway runs between Daejon and Sejong and its entire bike lane on the 32 km stretch is covered with solar roof panels. Not only do they generate sufficient electricity, but they also isolate cyclists from traffic and protect them from the sun.
The two-way bike lane is constructed right in the middle of the road, while there are three other lanes for vehicles to travel on either side. This also obstructs the high beam lights of oncoming cars.
Using the technology, the country can intern produce clean, renewable energy.
Solar-powered desalination technique by Chinese and American researchers
Desalination process is considered to be among the most energy-intensive activities. Now researchers have developed a solar desalination process that can treat contaminated water and generate steam for sterilizing medical instruments without requiring any power source other than sunlight itself.
The design includes a dark material that absorbs the sun’s heat and a thin water layer above a perforated material that sits atop a deep reservoir of salty water such as a tank or a pond. The holes allow for a natural convective circulation between the warmer upper layer of water and the colder reservoir below and draw the salt from the water.
Not only is the solar-powered desalination method efficient but also highly cost-effective.
Saudi Arabia’s goal of sustainable development using solar technology
Dry-climate arid regions are prone to droughts and often face water scarcity. While local food production would have been a distant dream for countries that host mostly deserts, scientists in Saudi Arabia have developed a unique solution using solar technology.
In an experiment, they designed a solar-driven system that could successfully cultivate spinach using water drawn from the air while producing electricity. This proof-of-concept design has demonstrated a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.
“Our goal is to create an integrated system of clean energy, water, and food production, especially the water-creation part in our design, which sets us apart from current agrophotovoltaics,” says senior researcher Peng Wang.

Middle East renewable energy ambitions face new challenges
The de-facto shutdown of much of the global economy in the first four months of 2020 caused by measures to stop the spread of coronavirus (Covid-19) is challenging many of the drivers of business growth and investment in the Middle East and North Africa. The collapse of oil prices and fall in tourism and consumer spending has raised deep questions about some of the region’s highest growth sectors.
One sector that shows no sign of disappearing is renewables. While the supply chain for projects has been disrupted, and the commercial model for privately finance power plants has been upset, the region remains committed to diversifying is energy sources and lowering its costs through renewables.
With about 28GW of renewable energy production capacity installed across the Middle East and North Africa (Mena), of which by far the biggest component is hydropower with 21GW, renewable energy represents only 7 per cent of the region’s power generation capacity. But with electricity demand rising at about 5 per cent a year, and with a shortage of readily available natural gas supplies, expanding renewables capacity is now one of the top policy priorities for governments in the region.
Boosted by falling technology costs and the drive to reduce carbon dioxide emissions, most countries are planning and procuring solar and wind projects. Across the region, governments have set ambitious clean energy targets, with Dubai the most aggressive, aiming for 75 per cent of its energy to come from clean sources by 2050. At the start of 2020, about 98GW of new renewable energy generation capacity was planned across the region, with 39GW of additional capacity due to come on stream by 2025.
The latest edition of Abu Dhabi’s World Future Energy Summit (WFES) in January 2020, highlighted the strides that have been taken in the region, and particularly by the UAE, to play a leading role in the transition from unsustainable carbon-production to sustainable renewable energy.
Completion of the GCC’s first utility-scale renewables projects has increased confidence among governments, developers and financiers. This has reduced the cost of financing and delivering projects. The market also expects greater adoption of small and medium-scale schemes such as rooftop solar.
At present, it is countries with hydropower capabilities that have the highest renewables capacity. The landscape is changing rapidly however as a series of large-scale solar and wind projects are being delivered. But as renewables move from the fringes to the centre of the region’s energy eco-system, regulators, investors and consumers must overcome several structural and technical obstacles.
Regulatory reform is the biggest challenge facing renewables. Merging renewable energy, primarily photovoltaic solar power, into power grids requires policy adjustments and new regulations. This includes ensuring grid flexibility and stability, integrating new technologies such as battery-storage and electric vehicles, and establishing commercially-attractive business models. Another challenge is to break the link between electricity and water production that is hard-coded into the region’s utilities.
The hydrocarbon producing countries of the MENA region believe in their preeminent albeit shrinking source of revenues for decades. But, as shown by some counties of the Gulf net-zero recent pledge, they see economic and political opportunities in moving to the green energy transition. Accelerated renewables-based electrification paves the way for a post-fossil future by Nature Energy explains how the world and particularly the EU in order to achieve its climate and geopolitical goals, it will need to substantially increase its engagement with Gulf states.
Accelerated renewables-based electrification paves the way for a post-fossil future
The research was published in Nature Energy.
Cost-slashing innovations are underway in the electric power sector and could give electricity the lead over fossil-based combustion fuels in the world’s energy supply by mid-century. When combined with a global carbon price, these developments can catalyze emission reductions to reach the Paris climate targets, while reducing the need for controversial negative emissions, a new study finds.
“Today, 80 percent of all energy demands for industry, mobility or heating buildings is met by burning—mostly fossil—fuels directly, and only 20 percent by electricity. Our research finds that relation can be pretty much reversed by 2050, making the easy-to-decarbonise electricity the mainstay of global energy supply,” says Gunnar Luderer, author of the new study and researcher the Potsdam Institute for Climate Impact Research. “For the longest time, fossil fuels were cheap and accessible, whilst electricity was the precious and pricier source of energy. Renewable electricity generation—especially from solar photovoltaics—has become cheaper at breath-taking speed, a pace that most climate models have so far underestimated. Over the last decade, alone prices for solar electricity fell by 80 percent, and further cost reductions are expected in the future. This development has the potential to fundamentally revolutionize energy systems. Our computer simulations show that together with global carbon pricing, green electricity can become the cheapest form of energy by 2050, and supply up to three quarters of all demand.”
The reasons lie mainly in the ground-breaking technological progress in solar and wind power generation, but also, in the end, uses of electric energy. Costs per kilowatt hour solar or wind power are steeply falling while battery technology e.g. in cars is improving at great speed. Heat pumps use less energy per unit of heat output than any type of boiler and are becoming increasingly competitive not only in buildings, but also in industrial applications. “You can electrify more end-uses than you think and for those cases actually reduce the energy consumption compared to current levels,” explains Silvia Madeddu, co-author and also researcher at the Potsdam Institute.
“Take steel production: Electrifying the melting of recycled steel, the so-called secondary steel, reduces the total process energy required and lowers the carbon intensity per ton of steel produced,” says Madeddu. “All in all, we find that more than half of all energy demand from industry can be electrified by 2050.” However, some bottlenecks to electrification do remain, the researchers point out. Slowest in the race to decarbonisation are long-haul aviation, shipping, and chemical feedstocks, i.e. fossil fuels used as raw materials in chemicals production.
Limiting the reliance on negative emissions
The scale of the technological progress holds great opportunities for countries to leapfrog and for investors alike. However, not every technology is a success story so far. “In this study, we constrained the reliance on technologies which aim at taking carbon out of the atmosphere, simply because they have proven to be more difficult to scale than previously anticipated: Carbon Capture and Storage has not seen the sharp fall in costs that, say, solar power has. Biomass, in turn, crucially competes with food production for land use,” Luderer lays out. “Interestingly, we found that the accelerated electrification of energy demands can more than compensate for a shortfall of biomass and CCS, still keeping the 1.5 degrees Celsius goal within reach while reducing land requirements for energy crops by two thirds.”
Era of electricity will come—but global climate policy must accelerate it to meet climate goals
“The era of electricity will come either way. But only sweeping regulation of fossil fuels across sectors and world regions—most importantly some form of carbon pricing—can ensure it happens in due time to reach 1.5 degrees,” Luderer says. Indeed, the simulations show that even if no climate policy at all is enacted, electricity will double in share over the course of the century. Yet in order to meet the goals of the Paris Agreement of limiting global warming to well below two degrees, decisive and global political coordination is crucial: pricing carbon, scrapping levies on electricity, expanding grid infrastructure, and redesigning electricity markets to reward storage and flexible demands. Here, hydrogen will be a crucial chain link, as it can flexibly convert renewable electricity into green fuels for sectors that cannot be electrified directly. “If these elements come together, the prospects of a renewables-based green energy future look truly electrifying,” says Luderer.
Greening deserts in which India powers renewable energy ambitions with solar push could be a good inspiring move for all those countries of the MENA region. An initiative commensurate with this country’s Prime Minister’s words at the COP26.

The arid state of Rajasthan sees 325 sunny days each year, making it perfectly placed for the solar power revolution
As camels munch on the fringes of Thar desert, an oasis of blue solar panels stretches further than the eye can see at Bhadla Park—a cornerstone of India’s bid to become a clean energy powerhouse. Currently, coal powers 70 percent of the nation’s electricity generation, but Indian Prime Minister Narendra Modi has pledged that by 2030, India will produce more energy through solar and other renewables than its entire grid now.
“First, India will increase its non-fossil energy capacity to 500 gigawatts… Second, by 2030, 50 percent of our energy requirements will come from renewable resources,” Modi told the COP26 climate summit in Glasgow.
The arid state of Rajasthan, where Bhadla Park takes up an area almost the size of San Marino, sees 325 sunny days each year, making it perfectly placed for the solar power revolution, officials say.
Once an expanse of desert, authorities have capitalised on the sparsely populated area, claiming minimal displacement of local communities. Today robots clean dust and sand off an estimated 10 million solar panels, while a few hundred humans monitor.
This pursuit of a greener future is fuelled by necessity.
India, home to 1.3 billion people and poised to overtake China as the most populous country, has a growing and voracious appetite for energy—but it is also on the frontline of climate change.
In the next two decades, it has to add a power system the size of Europe’s to meet demand for its swelling population, according to the International Energy Agency (IEA), but it also has to tackle toxic air quality in its big cities.
“India is one of the most vulnerable countries in the world for climate change and that is why it has this big push on renewables to decarbonise the power sector, but also reduce air pollution,” Arunabha Ghosh, climate policy expert from the Council on Energy, Environment and Water, told AFP.
But experts say the country—the world’s third-biggest carbon emitter—is some way from reaching its green targets, with coal set to remain a key part of the energy mix in the coming years.
Although India’s green energy has increased five-fold in just over a decade to 100GW this year, the sector now needs to grow by the same proportion again to meet its 2030 goals.
“I believe this is more of an aspirational target… to show to the world that we are moving in the right direction,” Vinay Rustagi from renewable energy consultancy Bridge to India, told AFP.
“But it would be a big stretch and seems highly unrealistic, in view of various demand and supply challenges,” Rustagi said.
Proponents point to Bhadla Solar Park, one of the largest in the world, as an example of how innovation, technology, and public and private finance can drive swift change.
“We’ve huge chunks of land where there’s not a blade of grass. Now you don’t see the ground anymore. You just see solar panels. It’s such a huge transformation,” Subodh Agarwal, Rajasthan’s additional chief secretary for energy, told AFP.
Authorities are incentivising renewables firms to set up in the region, known as the “desert state”. Agarwal says demand has “accelerated” since 2019.
“It will be a different Rajasthan. It will be the solar state,” he said of the next decade.
If this surge is sustained then coal-fired power for electricity generation could peak by 2024, according to Institute for Energy Economics and Financial Analysis (IEEFA) projections.
Currently, solar power accounts for four percent of electricity generation. Before Modi’s announcement the IEA estimated solar and coal will converge at around 30 percent each by 2040 based on current policies.
India’s billionaires, including Asia’s two richest men Mukesh Ambani and Gautam Adani, are pledging huge investments, while Modi is setting up a renewables park the size of Singapore in his home state of Gujarat.
Show me the money
But reshaping an entire power network takes time and money, analysts warn.
“India expects developed countries to provide climate finance of $1 trillion at the earliest. Today it is necessary that as we track the progress made in climate mitigation, we should also track climate finance,” he told more than 120 leaders at the critical talks.
Farmer and doctor Amit Singh’s three-acre family farmland in Rajasthan’s Bhaloji village was running out of water and hit by frequent power outages.
“I always saw the sun and its rays and wondered… why not harness it to generate electricity?,” he said.
Singh first installed rooftop panels at his small hospital which generated half of its energy needs.
He then invested family savings into a government-linked project on his land.
The mini-solar farm cost 35 million rupees ($450,000) and Singh sells electricity to the grid for 400,000 rupees a month.
“It’s the ultimate source of energy, which is otherwise going to waste… I feel I’m contributing to the developmental needs of my village,” he added.
Ghosh said it was vital to bring down costs.
“When a farmer is able to generate power from their solar plant near their farm and pump out water—we are then able to bring the energy transition closer to the people,” he added.
Pratibha Pai, the founder-director of Chirag Rural Development Foundation which has brought solar to more than 100,000 villagers, believes in clean energy’s transformative role.
She said: “We start with solar power… we end with safe drinking water, power for dark village roads, power for little rural schools which will hopefully script the story of a ‘big’ India.”
The World Economic Forum (WEF)’s article is a snapshot, at this conjecture, of the current vital decarbonisation awareness process throughout the world. In it, Ekaterina Miroshnik and Adam Sieminski ask How can we get hydrocarbon-rich nations to board the EV wagon? So here are the authors’ answers.
How can we get hydrocarbon-rich nations to board the EV wagon?
As the fourth largest source of carbon emissions, global transport must decarbonize.
Near-term reductions are most feasible in the light-duty vehicle sector.
Supply-side policies could be more effective in encouraging hydrocarbon-rich states to participate.
Hydrocarbon fuels account for more than 80% of commercially traded energy consumption. The abundance, convenience and affordability of fossil fuels have generated economic growth and made life better for billions of people. But the emissions and climate challenges associated with combustion are significant, and policy-makers around the world must limit the rise in global temperatures caused by greenhouse gas (GHG) emissions.
Global transport is the fourth largest source of GHGs, producing about 23% of global energy-related CO2 emissions. About 73% of transport emissions come from road vehicles including cars and trucks, 22% from planes and ships, and 1% from trains. GHG emissions reduction in transport is expected to significantly contribute to meeting the Paris Agreement goals.
GHG emission reduction from long-range heavy-duty transportation (trucks, trains, ships, planes) will likely require substantial R&D breakthroughs and policy interventions, because green technologies for these vehicle segments are not yet commercial. The majority of near-term GHG emission reductions in the transport sector are projected to come from electrification of light-duty vehicles (LDVs) as well as buses, where such technology is already commercial.
Governments globally have adopted various policies to support LDV electrification. Tax and other incentives to reduce the upfront price of electric cars are among the most commonly used policy levers. Using such a model, Norway, a hydrocarbon-rich economy, achieved the highest penetration of EVs in Europe. However, such measures can be expensive. The cost of reducing tailpipe CO2 through subsidies to EV alternatives can be as high as $1,000 per ton, significantly higher than other approaches to reducing carbon.
Demand-side measures can incentivize consumers, but also act to spur the automotive industry by helping the automakers recover their R&D investments on EVs and by allowing them to charge relatively higher prices for EVs. These incentives are part of governmental energy and environment policy, and industrial policies, designed to support local innovation and manufacturing.
Incentivizing the fossil fuel hubs
Demand-side policies are difficult to justify in countries without a local EV manufacturing industry, as is currently the case with countries in the Middle East and North Africa (MENA) region. Additionally, market barriers to EVs in the MENA region and in Eurasia are exacerbated by the policies that tend to favour hydrocarbon fuels use, reducing consumer incentives to adopt electric vehicles by lowering their operational cost advantage. Though government support for fossil fuels is phasing out over time in most MENA countries, economies in Eurasia have been taking very slow steps in this area.
An alternative approach for the regions with an abundance of fossil fuels, especially if the goal is long-term GHG emissions reduction that is also highly cost-effective, is to emphasize technology-neutral supply-side policies, such as fuel economy standards. Such policies are based on a combination of more stringent technology-neutral performance standards with credit-based mechanisms to incentivize the uptake of lower emission vehicles. Such technology-neutral standards offer the possibility of utilizing high-efficiency gasoline-electric hybrids or high-compression internal combustion engine vehicles as affordable interim solutions. In the longer term, there is the possibility of utilizing alternative technologies once they become available, including mobile carbon-capture technology.
Saudi Arabia, led by the Saudi Energy Efficiency Center, is among the first MENA countries to have adopted fuel economy standards. Outside the region, another example includes the recent revision in the European Union’s CO2 emission standards for LDVs. In such a case, the speed and extent of GHG emissions reduction depends on how stringent the implemented standards prove to be.
While an EV is emission-free on the road, it is useful to calculate the net carbon emissions associated with using one by considering the energy mix that provides the electricity to charge it. Ideally, the energy used to charge EVs should be generated from low-carbon or carbon-neutral sources, so that EV deployment results in overall net emissions lower than levels generated by internal combustion (ICE) engine vehicles.
Countries possessing significant shares of renewable energy like hydro, solar and wind in their energy mix are better suited for EV deployment. For example, countries such as Georgia and Tajikistan (both have a substantial share of hydropower) have increased investments in electric urban transport recently.
This does not mean that countries with inexpensive and abundant fossil fuels cannot still adopt EVs and reduce emissions. Hydrocarbon-rich nations can shift their generation from marginal sources toward lower-emission alternatives. For example, Saudi Arabia has announced an ambitious target aiming to generate 50% of its power needs using renewable energy by 2030, with the remainder provided by natural gas. Renewable electricity costs as well as battery costs for EVs, have been falling sharply. If the trend continues, EVs may eventually be suitable for general use in emerging markets, including in the MENA and Eurasia regions.
However, a rapid increase in demand for the core battery materials (e.g. cobalt, lithium), combined with constrained supply, may lead to significant increases in the cost of raw materials. Such increases could increase battery prices and ultimately electric vehicles prices, which could act as a barrier to EV adoption in the short term.
Another barrier is the lack of widespread EV charging infrastructure. Going forward, it we must build roads with an eye to a future where a significant proportion of vehicles could be EVs. This means that at the planning and design phase, road corridors need to be equipped with high-capacity EV chargers within existing fueling stations. To do so, in many cases it might be important to upgrade the local electrical grids and substations to handle these fast chargers, which consume significant energy.
Challenges like air pollution in cities continue to worsen, which should lead electorates exercising more pressure on local authorities to advance green policies. Cities are likely to become the e-mobility change champions in Eurasia (e.g., in Kazakhstan, Uzbekistan, Azerbaijan) with many embracing green development concepts and preparing green city action plans (GCAPs). GCAPs will focus on developing e-mobility strategies and prioritizing investments in electric transport (buses, trolleybuses, taxis, metro and light rail transport systems). The bottom-up pressure will encourage mayors and city councils to speed up electrification of transport, while greening electricity supply.
With the right policy mix and synergy between the power and transportation sectors, as well as supportive investment by multilateral development banks to eco-responsible governments, all countries – including those who most rely on fossil fuels – have an opportunity to reduce their transportation-based GHG emissions.
