Dr. Surekha Deshmukh holds a Ph.D in Electrical Engineering and is a Domain Consultant at the IoT and Digital Engineering Unit of TATA Consultancy Services (TCS) in Pune, India. She is a Senior member of IEEE and has been a member of the IEEE Power and Energy Society for more than 20 years, serving in many leadership roles. Along with being a Chair of the IEEE Pune Section, Dr. Deshmukh also contributes to IEEE's global initiatives serving as chair of the IEEE Smart Cities Committee's Women in Engineering (WIE) group and the Web Presence Subcommittee of the IEEE AdHoc Committee on Technology for a Sustainable Climate.

Dr. Deshmukh addresses the future of power grid innovations and the promising technologies supporting it.
Before we go into specific questions, here is the context of the energy transition trends, and what it means for the future power grid.
The transition from fossil fuels to renewable energy is no longer just a vision, it is a rapidly progressing reality. According to the International Energy Agency (IEA), by 2030, the global share of electricity generated from fossil fuels is expected to fall to 73% . In contrast, according to The International Renewable Energy Agency (IRENA), renewable energy sources are set to supply around 77% of global electricity by 2050 . Countries such as the United States, Australia, China, Japan, Europe, and the UK are leading this shift by investing in Distributed Energy Resources (DER), as models to support dynamic energy shifts.

Technologies like energy storage systems and biofuel backup generators are ensuring the constant availability of power. Investments in DER are growing, estimated to increase from $141billion in 2023 to over $240 billion in 2028. The E-mobility sector is also transforming, and Electric vehicles (EVs) are becoming more affordable, supported by favorable policies that encourage adoption. According to the IAE, there are about 40 million EVs on the road today, with EVs projected to be more than 35% of total car sales by 2030. As a result, the global market for vehicle-charging stations is expected to increase. Approximately 8 million public charging points were installed worldwide by the end of 2023, a 40% increase over 2022.

The widespread electrification required to support the growing needs of consumers will significantly increase the demand on the electricity distribution network. Meeting this demand will necessitate costly upgrades to local infrastructure, which may face resistance from residents, who are likely to bear the financial burden. Additionally, expanding the power distribution network alone is not a sustainable solution. Prioritizing energy efficiency measures to reduce overall demand will enable consumers to achieve more with less energy.

Therefore, it is crucial to fully comprehend the impact and the implications of integrating low-carbon renewable energy sources into smart grid systems in the coming years. IEEE offers education and credentialing in Distributed Energy Systems.

Storage systems enhance the reliability of green energy through a variety of solutions like flow batteries and compressed air energy storage.

Optimizing the techno-economics of these hybrid systems is key to their commercial success. Trust in energy storage is driving the reliable operation of renewable energy portfolios.
How are microgrids and virtual power plants (VPPs) redefining energy resilience and decentralization, and what role do they play in the broader context of the energy transition?
The energy landscape is changing rapidly due to socio-political factors, regulatory changes, and advancements in technology. Microgrids and virtual power plants (VPPs) are at the forefront of this transformation, contributing to decentralized energy systems that are both resilient and adaptable. Microgrids, which generate and consume power locally, offer operational advantages such as improved energy efficiency, enhanced reliability, and continuous power supply.

Electric vehicles and fleets are now capable of acting as virtual power plants, providing immediate backup to the grid and helping balance the energy demand. With reduced power loss and deployed grid-edge technologies, microgrids have demonstrated their ability to operate independently while also offering the potential to integrate with larger networks when needed.

The ability of microgrids to scale according to demand, combined with their comparatively low investment costs, makes them a key player in the fast-tracked energy transition. Microgrids are a viable solution to meet the growing demand for decentralized power, ensuring reliability while enabling renewable energy to thrive.
In what ways are predictive analytics transforming grid operations, from load forecasting to predictive maintenance, and what benefits do they bring to managing renewable energy variability?
The application of predictive analytics is revolutionizing the way utility companies manage the grid. With the increased integration of renewable energy sources, AI and data-driven insights are becoming critical for optimizing grid operations.

AI-powered predictive models can forecast energy demand, solar power generation, and even potential equipment failures based on historical data. These models help utilities make informed decisions, reduce downtime, and improve grid reliability. Predictive analytics is also playing a role in energy trading, where accurate predictions of power availability and pricing can mitigate risks and optimize transactions.
How is the development of hydrogen and Power-to-X technologies contributing to the decarbonization of power grids, and what are the potential benefits and challenges of these innovations?
Hydrogen and Power-to-X technologies are set to play a pivotal role in decarbonizing the power grid. As we move towards cleaner energy solutions, hydrogen is emerging as one of the most promising alternatives. Depending on its production method, hydrogen can be classified as gray, blue, or green, with green hydrogen being the cleanest form.

Power-to-X technologies convert surplus renewable energy into other forms of energy, such as heat or fuel (like methane or methanol). These technologies not only support grid decarbonization, but also provide innovative ways to capture and store carbon, thus reducing the overall environmental impact of energy production.

The commercial viability of hydrogen and Power-to-X technologies is still evolving, but they hold great potential for transforming the energy landscape.

How Engineers Can Help Protect Earth From Worsening Climate Change Technologies such as SaaS and IoT can play major roles

# data[].attributes.attachment_link.readable_text
Earth Day, which is celebrated annually on 22 April, aims to drive transformative change by educating people about what they can do to help. The day reminds us of the need to protect our planet and its ecosystems against the worsening climate crisis.

Our planet is no longer the same as it was even just a decade ago. The climate crisis is threatening people across the world, as well as every species of animal and plant life. We need to address the crisis now in a sustainable way. Fortunately, we still have a narrow window of opportunity to alter the Earth's climate path, and I believe we can do it.

Climate change is a global societal crisis that is causing devastating consequences. Its costs have been projected as high as US $23 trillion in reduced annual global economic output, according to Swiss Re, a reinsurance company. Multifaceted collective efforts are necessary to address the crisis.

Engineers and technologists can and should play major roles in creating a greener planet, creating tools that address environmental degradation.
HOW THE CRISIS AFFECTS US
In the past few years, we've witnessed devastating cases of extreme weather all over the world, including deadly floods, massive forest fires, and severe droughts. Lives and businesses are being severely affected, and the cost of recovering after each event continues to mount.

The climate crisis is also having a severe effect on the planet, which is being battered by pollution, deforestation, and soil degradation.

About 7 million people every year die from diseases caused by air pollution, such as chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections, according to the World Health Organization. Ninety-nine percent of the global population breathes in air that exceeds WHO-guideline limits on pollutants, with low- and middle-income countries suffering from the highest exposures. More than half the world's people live in urban areas, yet only 12 percent of cities achieve WHO guidelines for air quality. To create a sustainable environment, we need to contain air pollution.

Deforestation is contributing to climate change. Trees capture and store atmospheric carbon and help cool the globe's temperature. Deforestation has caused the Amazon rainforest and similar areas to lose their ability to recover from disturbances such as drought, wildfires, and human development, according to a recent article published in Scientific American. The loss of the Amazon rainforest would cause large-scale drying across the region. In response, the circulation of the atmosphere could change-which would alter weather patterns around the world, the article says.

About 95 percent of food production relies on topsoil. The soil also helps to address the climate crisis, as it stores more carbon than the world's plants combined. The microbes and minerals in soil systems regulate water, cycle nutrients, filter pollutants, physically support plants, and sequester greenhouse gasses.

But Earth's soil is being spoiled and degraded, presenting us with several risks. According to a 2017 United Nations -supported study, a third of the planet's land is severely degraded, and fertile soil is being lost at an alarming rate.

The climate crisis has serious health consequences, the WHO warned in its recent COP24 report. Direct health impacts include an increase in respiratory and cardiovascular disease and injuries or death due to extreme weather events. Climate change also causes indirect effects on health, such as food and water insecurity, the spread of climate-sensitive infectious diseases, and population displacement.
TECHNOLOGICAL SOLUTIONS
There are many ways that IEEE members from the technical and scientific community can help. Engineers and computer professionals can use information technologies such as cloud-based software-as-a-service (SaaS), Earth's digital twin, and the Internet of Things (IoT) to help make buildings, energy production, farms, health care, and manufacturing greener.

SaaS platforms, such as Project Canary of Denver, help energy companies track, measure, and score the impact of methane and other volatile organic compounds on the environment across the energy supply chain. Canary uses high-fidelity spectroscopy-based methane detection and emissions quantification for the oil and gas sectors. The SaaS platform also uses laser-based gas analyzers to detect methane, formaldehyde, and more.

The IoT has vast potential to address sustainability by making energy systems more connected, improving their operational efficiency, and reducing the carbon intensity of buildings, manufacturing, and transportation. It also can lower energy consumption through smart operations and improve resource utilization. By using IoT-equipped sensors, deforestation and poaching can be monitored. IoT food container tags can reduce food and water waste.

Engineers and technologists can and should play major roles in creating a greener planet with technology that addresses environmental degradation.

Using a digital model of the Earth-or digital twin-environmental impacts can be studied. A new model developed by the European Commission's Destination Earth initiative is designed to track the impact of humans on water, food, and energy management. Data collected through the digital twin can help predict environmental impacts and enable remedial measures to be taken.

Artificial intelligence, data science, and distributed ledger technology can play major roles as well.

Researchers are developing smart materials, next-generation batteries, autonomous vehicles, carbon capture and storage, hydrogen-powered fuel cells, precision agriculture, and 4D printing that might help solve environmental problems.

Although information technologies and similar tools leave their own environmental footprint, they are often small compared with their positive contribution toward creating a greener planet. And efforts are underway to make the technologies greener.
CALL TO ACTION
Undoubtedly, environmental degradation is a complex, global problem and the defining challenge of our time. Our inaction could jeopardize the well-being of current and future generations.

We must envision and ensure a sustainable future through responsible planning, development of effective solutions leveraging technological advances, actionable regulations, and sound practices. We need an environmental mindset as well as systemic transformation and individual behavioral changes.

Let's be optimistic in what we do. Optimism can drive us to achievement. As German poet Johann Wolfgang von Goethe said: "Knowing is not enough; we must apply. Willing is not enough; we must do."

If we don't care about our environment and the future of our planet, then who will? Let's treat every day as Earth Day. Let's invest in creating and sustaining a better environment than the one we inherited.

Let's pledge-and act now-to create a cleaner, greener planet. If not now, when?
