Experts confirm that current and future needs for electricity may soon exceed our global supply. New AI-driven data centers, electric vehicle charging stations, energy-intensive manufacturing operations, and a growing volume of internet connections are placing an increasing strain on outdated electric grids. This looming reality has since challenged utilities, grid operators, technologists, and regulators to reconcile existing electric capacity with rising demand.

It subsequently comes as no surprise that interest in renewable energy sources and related green technologies continues to grow. These solutions reduce carbon footprints, enhance global sustainability, and combat the effects of climate change.

Energy industry professionals have been addressing the disparity between electric supply and demand in various ways. Solutions include everything from increasing overall reliance on renewable energy sources to employing IoT-enabled automation devices to optimize electric distribution, reduce waste, and enhance overall electric efficiency, reliability, and performance.

A Green Energy Revolution

As utilities continue to integrate renewable energy sources into their mix, numerous engineering advancements are helping them meet energy supply targets and align with the United Nations’ Sustainable Development Goals for 2030.

In the solar power arena, scientists are working with a highly responsive family of crystalline compounds called perovskites to deliver more power from existing solar panel devices. Based on their ability to analyze massive amounts of real-world data, quantum computing and AI are also being harnessed to help achieve more efficient solar cell design. Thanks to these technological achievements, solar energy has become more affordable, with costs dropping by some 90% in the last decade. Based on this and other factors, the World Economic Forum predicts that solar power is on track to be the world’s dominant power source by 2050.

The Future of Sustainable Energy

Though wind turbines are currently a less prevalent source of renewable energy worldwide than solar power, advancements in these devices are similarly helping to make them more powerful, efficient, and accessible. An engineering team at England’s University of Birmingham recently used AI to test more than 2,000 different blade designs and “explore design possibilities beyond the scope of traditional human experimentation.” Their research led to the development of the ‘Birmingham Blade,’ an optimally shaped and weighted blade that’s up to seven times more efficient than existing designs and scheduled to be commercially available later this year. The computational powers of AI also accelerated the blade design process, reducing development time from years to weeks.

As a result of these and other breakthroughs in the green energy industry, renewable energy sources are growing globally. In 2024, all renewable energy sources combined – including wind, solar, hydropower, biomass, and geothermal – provided over 32% of the world’s electricity, nearly double the level that renewable sources represented 25 years earlier. In the U.S., the use of renewables accounted for over 24% of total electricity production in 2024, up 4% from 2023.

Smart Grid innovations

On top of the growing use of renewable energy sources, utilities are increasingly relying on intelligent “edge devices” to optimize electricity usage. This category includes the use of IoT-driven sensors and smart two-way meters to provide continuous monitoring and enable real-time insights into grid conditions. By tracking each user’s energy consumption patterns, these smart devices promote informed decision-making that allows utilities and users to optimize their energy usage and better integrate solar, wind, and other renewable sources into their energy portfolio. The additional ability to store this energy through battery energy storage systems (BESS) further helps to address supply shortfalls and stabilize/optimize the grid.

Transportation and Sustainability

Other technological developments are also making great strides towards reducing our global reliance on fossil fuels and combatting climate change. In the transportation sector, ongoing advancements in electric vehicle design, regenerative braking, and electric drive train technology continue to deliver instant power, greater efficiency, and zero tailpipe emissions relative to conventional internal combustion engines.

The world is responding in kind, with global sales of electric vehicles hitting a record 17 million in 2024 (a 25% growth over 2023 levels). This trend will continue to reduce the world’s carbon footprint. According to the European Environment Agency (EEA), electric vehicles emit 30% less greenhouse gases than traditional gasoline-fueled cars and their lifecycle emissions could decrease by at least 73% by 2050. In the U.S. alone, experts believe that the widespread use of EVs will lower the country’s CO2 pollution by two-thirds.

plants-generate-electricity

While the global pandemic has created an uncertain future for renewables, new discoveries are giving researchers hope for a greener tomorrow. According to a pair of recently published studies from Tel Aviv University, two naturally abundant resources—plants and humidity—may revolutionize renewable energy in the future by generating electricity.

Can Plants Generate Electricity?

One of the studies revealed that plants, which contain chlorophyll, may be able to act as natural solar panels. However, scientists are still determining how the electrical currents of plants can be “plugged into” man-made devices.

“At home, an electric current can be wired to many devices. Just plug the device into a power outlet,” Iftach Yacoby, head of The Laboratory of Renewable Energy Studies at Tel Aviv University’s Faculty of Life Sciences, told CTECH. “But when you want to do it in plants, it’s about the order of nanometers. We have no idea where to plug the plugs. That’s what we did in this study.”

By using a hydrogen-producing enzyme to “sit in the socket” of  the plant cell, the researchers proved that they possess a socket for everything—even though it was nanotermically-sized. Previously just a theory, the researchers believe they will now be able to engineer any type of plant or kelp with the purpose of energy production.

Yacoby told CTECH that he wants to use plant enzymes to create ammonia, a compound traditionally used in fertilizers, that doesn’t pollute the environment. “If we can get plants to produce ammonia on their own, we don’t need to produce fertilizer at all. We can give up nitrogen fertilizer and allow plants to use nitrogen in the air without fertilizer,” he said.

While the technology is promising, it won’t be economical for at least another ten years. 

Water Vapor May One Day Charge Batteries

According to another study from Tel Aviv University, water vapor from the atmosphere may one day be harnessed to charge batteries.

Water is able to naturally generate electricity. For example, during thunderstorms, lightning forms along the various stages of cloud formations—beginning with water vapor and then transitioning to droplets and ice. 

In the 1800s, physicist Michael Faraday revealed that metal surfaces can be charged with water droplets when there is friction between them.

Knowing that water vapor can create electrical charges during molecular collisions and generate static electricity through friction, the researchers performed an experiment to identify the voltage between two separate metals when exposed to humidity. They exposed one of the metals to high relative humidity, while keeping the other metal grounded. When the air was dry, there was no charge. When they elevated the humidity to over 60%, however, it did generate a voltage. This voltage then dissipated when they lowered the humidity.

The findings contradict traditional thinking about humidity as it pertains to electricity. While water is considered an effective conductor of electricity, it has not traditionally been seen as a way to produce charges on surfaces. “However, it seems that things are different once the relative humidity exceeds a certain threshold,” Professor Colin Price told Science Daily. 

According to the findings, it may be possible for humid air to charge metal surfaces to roughly a single volt. 

“If a AA battery is 1.5V, there may be a practical application in the future: to develop batteries that can be charged from water vapor in the air,” Price said. “The results may be particularly important as a renewable source of energy in developing countries, where many communities still do not have access to electricity, but the humidity is constantly about 60%.”

In other words, given the abundance of humidity in warmer climates, the technology could potentially serve as an endless source of renewable energy in poorer regions that need it the most.

Smart grid technology is enabling the effective management and distribution of renewable energy sources such as solar, wind, and hydrogen. The smart grid connects a variety of distributed energy resource assets to the power grid. By leveraging the Internet of Things (IoT) to collect data on the smart grid, utilities are able to quickly detect and resolve service issues through continuous self-assessments. Because utilities no longer have to depend on customers to report outages, this self-healing capability is vital component of the smart grid.

Smart Grid Management of Renewable Energy

The relationship between the smart grid and renewable energy revolves around gathering data. For example, wind farms use mechanical gears that require each link to support multiple sensors. Each sensor is able to note current climate and environmental conditions. This information is then quickly sent though the grid to alert the utility of any issues, which improves both the quality of service and safety.

“You’ve got this story of this invisible, dangerous commodity that travels at the speed of light that we call electricity and for the last hundred-plus years most people could interact with it in only the most rudimentary ways,” says Mark Feasel, vice president of smart grid for Schneider Electric. Companies are now deploying much more advanced sensing devices. According to Feasel, some devices can continually capture information on electricity up to 60,000 times per second.

Semiconductor materials, such as silicon, are supporting the creation of green energy with smart grid technology. Due to their ability to hold millions of minuscule transistors, these materials have enabled IoT advancement. In turn, this advancement has allowed the smart grid to link up devices throughout the system, which ensures that the supply of energy is equal to the demand. It also keeps the current evenly distributed.

Smart grids equipped with parts made from semiconductor material reduce the usage of electricity. For example, electric vehicles can charge at night— a time when offices and homes are not typically using much electricity. Lights switches and furnaces can also automatically power on and off. In this way, energy usage becomes “smart” by not using more than what is needed.

Renewable Energy with Smart Grid Technology Initiatives

As smart grid technology becomes more promising, both local and federal governments are exploring potential grid improvements.

Thailand

By 2037, Thailand wants a third of its energy to be generated by renewable energy sources. This means that Thailand’s grid will need to be modernized to handle the varying levels of energy provided by renewable sources. Any modernization plans will also need to take the country’s growing demand for electric vehicles (EVs), which is predicted to grow in coming years.

“When we have more renewable energy, the grid will become more difficult to manage, and then we will need to give them more flexibility with the digital to make it smarter,” says Dr. Surat Tanterdtid, Chief of Enterprise Architecture of the Electricity Generating Authority of Thailand. Smart grid technology can help monitor and predict the supply of renewable energy into Thailand’s grid. This may allow the country to anticipate power outages and prepare accordingly.

New York

The New York State Energy Research and Development Authority is currently holding a competition in order to improve the state’s energy distribution. The Future Grid Challenge, which began in July, is part of a push to transition the state’s electric grid to renewable energy. A new statewide act includes requirements for a clean or carbon-free electricity sector by 2040 as well as an 85% greenhouse gas emissions drop by 2050.

The first round of funding will provide up to $6 million USD to projects that partner with Con Edison and Orange & Rockland Utilities. The goal of the competition is to improve data analytics, grid stability, and forecasting while reducing system losses. 

Modernizing the Smart Grid

One of the biggest frontiers in electrical engineering today is the development and implementation of smart grid technology. Fueled by the global demand for greener technologies and alternative fuels, environmentally-friendly smart grid technology has the ability to stimulate stagnant economies as well as change the way power is delivered to electricity consumers around the world.
