The Future of Clean Energy & Technology

 

With climate change causing somewhat of a meltdown across the globe, the world is rapidly transitioning towards clean energy sources to offset the negative effect humans are having on Earth. This seismic shift is more than a trend. It's a necessity. It's a step towards a greener and cleaner future driven by the catastrophe of climate change, depleting fossil fuel reserves and a global quest for energy independence. Previously confined to academic articles and research labs, the phenomenon of green energy has now become a revolution. 

Climate change is now causing a massive reconsideration in industries and economics. It's also triggering a psychological revolution, changing human mindsets to reimagine our relationship with our planet.

But the question remains – what exactly is the future of clean energy and technology? Well, to answer it, we have written a comprehensive piece covering everything from what clean energy is, where it currently stands and what's its future. We will also explore the latest cleantech trends, technologies and innovations.

What Is Clean Energy?

The answer to the question—what is clean energy—in the simplest terms, is the energy that is produced through means that have little to no impact on the environment.

It's the energy that doesn't release toxic gases in the air, pollute our waters with harmful chemicals, or displace millions of acres of earth so we can charge our phones. Instead, it's about collaborating with nature and tapping into the endless power of sun, air and water.

So is clean energy just a trendy term used by companies as a marketing booster? Or is it really the lifeline we need for the next generation? Well, even if we leave the whole “climate change is real or not” debate aside and be pragmatic for a second, at the rate we are burning fossil fuel, it'll all be depleted by 2060. Even if we find new sources, they will only take us to the next century, to say the most. Then what? 

Yes, clean energy promises a better, cleaner future, but more importantly, it's the only way we have to survive in the future. So, no matter if you believe in climate change or not, you should still believe in clean energy—there is no way around it.

The Nuanced Nature of Clean Energy

Even though solar and wind power are often considered to be the only two sources of 100% clean energy transition, the reality is far more diverse. Hydroelectric power, for example, has long been the foundation of renewable energy. As per the available records, the first ever hydroelectric farm was developed in 1887 by William Armstrong in England. Even though it only powered a single arc lamp, it laid the foundation for some of the most gigantic megastructures the human race has ever made.

Three Gorges Dams in China and Guri Dam in Venezuela, for example, are two of the biggest dams in the world. Combined, they produce over 136 TWh of electricity annually. That's equivalent to the energy generated by burning approximately 55 million metric tonnes of coal and releasing 106 million metric tonnes of CO2 and other toxic gases in the air.

However, these massive hydropower plants do come with their own environmental and economic challenges. They require massive land coverage and impact underground water levels on river paths. They also have a negative impact on marine life and weather patterns. These drawbacks have led to a growing interest in small-scale or run-of-river systems that have a much smaller footprint.

Geothermal power generation is another clean energy source that is often overlooked. It revolves around using the Earth's internal heat to generate power and holds immense potential. Even though it's a relatively novel technology, countries like Iceland have long been using their unique geological position to harness this power, with geothermal providing about 25% of the country's total electricity production. With recent innovations and advancements in EGS, or Enhanced Geothermal Systems, this technology is now becoming more viable in regions where it was once thought unsuitable.

Biomass energy sourced from the decomposition of organic materials offers a complex but viable source of renewable energy. Although biomass energy offers a renewable replacement for fossil fuels in heating and manufacturing, concerns related to land utilisation and growing food impact have triggered continued disagreements among environmentalists and regulatory authorities about its large-scale use.

Apart from these, other sources of renewable, clean energy include the following.

• Ocean Thermal Energy Conversion (OTEC)

• Bio Energy

• Salinity Gradient Energy

• Piezoelectric Energy

• Wave Energy

• Tidal Power

• Hydrogen Energy

Renewable Energy Growth in the US

• Technological advancements

• Large-scale investments

• Rapid adoption by businesses

• Supportive government policies 

The growth of the renewable energy industry in the US is mostly driven by wind and solar power. The US now has solar power capacity of around 164,502 gigawatts in 2023 compared with a mear 17,691 just 10 year ago in 2014. While wind has also drastically increased from 181.66 terawatts to 425.24 terawatts in the same timeframe. Apart from solar and wind, the government and business have also paid significant attention to other renewable energy sectors, such as the following.

• Hydropower - 233.96 TWh

• Biomass - 47 Billion KWh

• Geothermal - 16 Billion KWh

As this renewable energy grows at such a rate, it's not just about economic or ecological viability; it's creating jobs and helping states work to fix their employment numbers. In fact, today, the renewable energy sector employs more than 3 million Americans.

Importance of Clean Energy in Today's World

The importance of clean energy extends way beyond environmental factors. Clean energy offers a solid path to sustainability as we face multiple challenges. First of all, today's geopolitical landscape featuring wars on multiple fronts have given rise to energy price fluctuations and compromised supply chains. This uncertainty is pushing governments to rethink their energy security strategies and invest in long-term solutions such as clean energy.

Clean energy solutions play a vital role in sustainable development goals (SDGs), which were set by the United Nations in 2015. These goals include universal access to affordable and reliable energy sources across the globe. Besides, other goals, such as reducing air pollution, developing and promoting new economic opportunities and improving public health, can all be achieved by tapping into the potential offered by clean energy.

The clean energy sector has also become a powerhouse for economic growth and job creation. At the end of 2023, 13.7 million jobs were created by the renewable agency sector, according to the International Renewable Energy Agency (IRENA). That's a considerable number, considering other major sectors have struggled during the last 5 years to maintain the availability of job opportunities.

The Role of Clean Energy Charging in Sustainable Development

So, what is clean energy charging? Clean energy charging stands at the intersection of renewable power generation and storage to use the energy produced by clean energy sources to power electric vehicles and other instruments. 

Simply put, it's about exclusively using clean energy to power mainly electronic vehicles. If the electricity used to charge EVs comes from traditional fossil fuels, it defeats the purpose. That's why clean energy charging is a vital connection between generating and actually using renewable energy.

The implementation of clean energy charging goes beyond simply plugging your vehicle or any electric tool in a plug. It requires a complex ecosystem featuring multiple technologies.

• On-site renewable energy generation

• Smart grid technologies

• Vehicle to grid technologies

• Energy storage systems

• Demand response systems

• Microgrids

However, we are at just the beginning, as there are several exciting innovations on the horizon. Wireless charging, for instance, holds massive potential in the near future. These wireless charging systems can be embedded into parking spaces or directly into roads, thus charging your vehicle as you cruise through the highway or walk around Tesco.

Combine this with AI-assisted charging, and consumers will no longer be required to think of how much battery their vehicle has. These AI algorithms will automatically detect battery levels and charge your vehicle on the road when needed. Other exciting clean energy charging technologies near completion include mobile charging solutions, ultrafast charging stations and instant battery swaps.

What is Electrification?

Electrification is the process of powering systems, devices, or whole regions by electricity. So an example of this would be an electric vehicle. However, we need to be careful because we cannot solve the energy crisis issues solely through electrification. For instance, if we charge batteries using fossil fuel power, it is not renewable. So it’s important to keep in mind electrification is not the sole answer to the problems we face.

Electrification is a multifaceted process. It means strengthening electric infrastructure and developing tools and machinery to run on electricity generated from renewable resources. It also includes the conversion of non-electric technologies to electric. This covers a wide array of sectors, from transportation (e.g., electric vehicles) to heating and cooling, farming, and many more things.

Clean Technology & Cleantech Examples

Clean technology, often referred to as cleantech, represents a broad spectrum of technologies, products and services designed to optimise the production and usage of clean energy. These include.

• Renewable Energy Generation Technologies

These are systems like solar panels or wind turbines that convert natural resources, such as sunlight and wind, into clean electricity without emitting harmful pollutants.

• Smart building materials

Materials designed to improve energy efficiency in construction, such as self-healing concrete or windows that adjust tint based on sunlight, reduce energy consumption in buildings.

• Energy Storage Solutions

Technologies like advanced batteries or pumped hydroelectric storage that store excess energy for later use enable a reliable supply from intermittent renewable sources like solar and wind.

• Water Purification & Desalination Solutions

These are technologies that clean and remove salt from water, providing safe drinking water in areas where fresh water is scarce.

• Nuclear Energy

Provides a highly efficient and stable source of power with a minimum release of toxic gases in the air. However, it often faces challenges related to nuclear waste disposal.

Vehicles or infrastructure that reduce reliance on fossil fuels, such as electric cars, public transit systems, or bike-sharing networks, minimise carbon emissions and air pollution.

Clean Tech Empowering Innovation Across US Industries

Clean tech is at the forefront of innovation across industries, driving development in almost all sectors. Material science, for example, is gaining massive investments to develop green materials. For instance, MIT has recently developed a new material that can passively cool buildings without using any energy.

Artificial intelligence and machine learning are also at the forefront of the green energy revolution. AI tools like Google DeepMind are being used to optimise the useage of energy and have resulted in a 40% reduction in energy consumption of data centres.

In addition to these, innovations in clean energy storage solutions are improving energy efficiency and grid sustainability. Another sector that is rapidly innovating is transportation, incorporating new and improved technologies on a regular basis. These technologies include everything from ultrafast charging to electric plans, trains, and even boats.

Farming is also greatly influenced by clean energy, as it's now adopting sustainable clean technologies such as precision agriculture (using drones, sensors, and data to optimise watering and fertilisation), vertical hydroponic farming to save water and energy, renewable energy incorporation (biogas, solar, and wind power), electric tractors and transportation vehicles, and much more.

Energy Storage – The Backbone of Renewable Energy Growth

Batteries are the unsung heroes of the clean energy revolution. They're what allow us to store solar power for nighttime use, drive electric cars for hundreds of miles, and balance the electrical grid. And they're getting better by the day.

Lithium-ion batteries have been the workhorses of the battery world for years, but new technologies are emerging that could change the game.

• Solid-state batteries –  These promise higher energy density, faster charging, and improved safety compared to traditional lithium-ion batteries. Toyota plans to showcase a solid-state battery-powered vehicle at the 2025 World Expo.

• Sodium-ion batteries – Using abundant, cheap sodium instead of lithium, these could be a game-changer for grid-scale storage. Chinese battery giant CATL has already started producing them.

• Lithium-sulphur batteries – With the potential for much higher energy density than lithium-ion, these could dramatically increase the range of electric vehicles.

While EV batteries get a lot of attention, grid-scale storage is where batteries could have their biggest impact. As we rely more on variable renewable energy sources like wind and solar, large-scale battery systems will be crucial for storing excess energy and releasing it when needed.

Companies like Tesla, with its Megapack, are already deploying massive battery systems that can power thousands of homes. As these systems become more common and more advanced, they'll play a key role in enabling a 100% renewable energy grid.

Clean Energy Tech in the US Commercial Sector

The commercial sector is one of the biggest energy consumers out there, which means it's also one of the areas with the most potential for clean energy adoption. And businesses are starting to realise that going green isn't just good for the planet – it's good for the bottom line profit, too.

Solar Taking Over

Commercial solar installations are on the rise. From big commercial stores to office buildings, petrol stations, and hotels, many businesses are thinking about solar. Why? It's economically more viable. These renewable sources only require one time investment and occasional maintenance, providing a more affordable and sustainable energy solution for businesses. The only current challenge in this regard is industry storage. Half of the total cost of incorporating solar panels goes towards batteries, which are prone to damage and can require a complete overhaul. The world is waiting for an innovative battery solution that can be rapidly charged and keep on giving energy for prolonged periods of time.

Smart Energy Management

But it's not just about generating clean energy – it's about using it smartly too. Advanced energy management systems are helping businesses optimise their energy use in real-time. These systems can adjust lighting, heating, and cooling based on occupancy and time of day, dramatically reducing energy waste.

The Benefits Stack Up

The benefits of commercial clean tech for businesses go beyond just lower energy bills (though that's certainly a plus). There's also increased energy independence, improved brand image, and in many cases, government incentives to sweeten the deal.

Integrating AI & Machine Learning in Clean Energy Systems

Artificial intelligence (AI) and machine learning (ML) are more than designing images and helping you write social media posts. They’re also playing a crucial role in the optimisation of clean energy. One of the biggest challenges with clean energy is dealing with variability. The sun doesn't shine all day long, and the wind doesn't blow all year round – so we need to make sure the energy we do store is used resourcefully. 

That's where AI in clean energy can help by predicting production based on weather forecasts, historical data, and real-time conditions. We can then optimise consumption and adjust the grid accordingly to ensure an uninterrupted power supply, even on those cloudy or snowy days.

Smart AI-powered gadgets can also drastically reduce energy waste. Smart thermostats, for example, can learn your preferences and adjust in real-time without any external input to maintain the temperature at the right levels.

Looking ahead, the integration of AI and ML in clean energy innovation is only going to deepen. We're moving towards a future where every aspect of our energy system—from generation to transmission to consumption—is optimised in real-time by intelligent systems.

How Clean Energy Tech Is Transforming Commercial Buildings

Commercial buildings are energy hogs, eating a massive chunk of global energy production. Everything in a building, from heating, cooling, ventilating, and lighting to lifts and escalators, requires energy. Relying solely on traditional energy sources for buildings can be a burden on both the economy and environment. Clean energy and technology provide a more sustainable solution. It's helping us rethink how we build and operate these massive structures.

It starts with the design. Using modelling software, architectures can optimise buildings for energy efficiency right from the very beginning. These smart tools can simulate energy efficiency in buildings in different conditions, allowing designers to make informed decisions in real-time. Clean buildings are more airy and use natural lighting to minimise energy consumption. Plus they are better insulated to help cold or warmth out.

Next comes in clean or green materials. These are specially designed materials that can optimise the energy efficiency of a building to its maximum. These include everything from smart paints keeping the interior cooler to innovative insulations maintaining comfortable temperatures.

Then come innovative tools and gadgets. Smart windows can tint automatically to reduce heat gain, cutting cooling costs. Advanced LED lighting systems adjust based on natural light levels and occupancy. High-efficiency heat pumps provide both heating and cooling, often powered by rooftop solar panels. Energy recovery ventilators recapture heat from exhaust air, reducing the energy needed for heating and cooling fresh air.

But perhaps the biggest game-changer is the use of building management systems (BMS) that tie all these technologies together. These systems collect data from thousands of sensors throughout the building, using AI to optimise energy use in real-time.

The result? Buildings that are not just more energy-efficient but more comfortable and productive for the people who work in them.
