Big data and AI algorithms help utilities make quick decisions in real-time because the electricity system is one of the most complicated infrastructures. In the renewables industry, AI has applications beyond grid analytics and management, such as power demand predictions and proactive maintenance of renewable energy sources. Additionally, it makes it possible for grid capacity forecasting apps and time-based autonomous trading and pricing to operate. Virtual power plants (VPP) are a supplement to the energy generation from utilities thanks to advancements in cloud computing. Start-ups also use data analytics and machine learning to build and evaluate the success of renewable energy models.

DESS localises the production and storage of renewable energy, addressing production irregularities. Start-ups provide a variety of battery and battery less solutions depending on the needs of the market and other factors. For instance, solid-state batteries are light and offer great energy density, but flow batteries use low and fluctuating energy. Capacitors and super capacitors are also utilised in applications that demand a lot of energy in a short amount of time. Start-ups are developing battery-free storage options such pumped hydro and compressed air technologies in response to worries about discharging, safety, and environmental contamination. The Power-to-X (P2X) technology, on the other hand, transforms excess energy into other types of energy, including heat or methane, for storage and reconversion.

The energy that comes from moving water is known as hydropower. Hydro energy is predictable and therefore more dependable than solar and wind energy. Hydroelectric dams offer high energy density while lowering reliance on traditional sources. Ocean-based energy derived from tides, currents, and waves is another option. The advancements made to these renewable energy sources' components and energy converters are aimed at increasing the efficiency of energy collection. Decentralized energy production is made possible by small-scale hydroelectric dams and tidal barrages in the hydro power sector. Through the use of the temperature gradient that is formed between the surface and deep water, ocean thermal energy conversion (OETC) captures energy. A small number of businesses are also using the salinity gradient created by the osmotic pressure difference between river and seawater as a source of useful energy.

Despite being one of the most ancient energy sources, wind energy is one of the primary trends due to its industry's quick evolution. To meet the need for land-based wind energy, start-ups are developing offshore and aerial wind turbines. Innovations in this area frequently connect with other energy sources like solar, tidal, or floating wind turbines. The aerodynamic designs of the blades are always improving to increase efficiency even more. Additionally, start-ups create effective turbines and generators for high energy conversion. One of the difficulties the industry is currently facing is the sustainability of blade material. Start-ups are developing bladeless technology and recyclable thermoplastic materials to make blades as a solution to this problem.

Bioenergy is a type of renewable energy derived from biomass sources. A liquid biofuel of gasoline-like quality is directly mixed for use in the vehicle. To achieve this quality, companies are improving their biofuel processes and processing technology. The majority of biofuel conversion processes such as hydrothermal liquefaction (HTL), pyrolysis, plasma technology, milling, and gasification use heat conversion to produce biofuels. In addition, improved techniques such as cryogenic, hydrate, in situ and membrane separation are used to remove sulfur and nitrogen content. Likewise, the fermentation process produces bioethanol, which can be easily mixed with gasoline. Fermentation also has the ability to convert waste, grains, and plants into bioethanol, providing feedstock versatility. Energy-dense raw materials, on the other hand, lead to optimal fuel quality. For this reason, start-ups and large companies are looking at algae and microalgae feedstock for use in the conversion processes described above.

Grid integration technologies primarily include transmission, distribution, and stabilization of renewable energy. Scaling up variable renewable energy generation is often far from demand centers which result in transmission and distribution losses. To overcome this, energy-efficient, grid electronic technologies such as Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductors are leveraged. The challenge of frequency and voltage fluctuation due to variable renewable energy generation is solved through microcontroller-based solutions. Despite these technologies, stabilization of the grid is a huge challenge due to intermittent energy usage. Vehicle to grid(V2G) technology empowers stabilization of the grid during peak hours while grid-to-vehicle (G2V) solutions leverage the vehicle as a storage unit. As a result, both the energy and transportation industry benefits.

Hydrogen gas has the highest energy density of any fuel and emits almost no greenhouse gases (GHG). However, most hydrogen comes from non-renewable sources in the form of gray or brown hydrogen. Over the last decade, the development of renewable energy and fuel cells has driven the switch to green hydrogen. Although clean, it also addresses the low energy conversion efficiency and transportation challenges of fuel cells. For these reasons, green hydrogen development focuses on improving hydrogen storage, transport and distribution.

The Department of Climatology, Atmospheric Sciences deals with the expression of weather and the assessment of the causes and realistic consequences of climate change and adaptation. Climatology deals with the same atmospheric approach as meteorology. However, it also attempts to recognize slower effects and long-term semantic adjustments. B. A small but measurable version of ocean movement and solar radiation at depth. It begins with the origins of Greek science in the 6th century BC. In 2000 BC, climatology developed along major lines. They are local climatology and body climatology. The first is to examine discrete and characteristic climatic phenomena in selected continental or sub-continental regions. The second involves a detailed study of the statistical analysis of many components of climate, primarily temperature, humidity, pressure, and wind speed, and the simple relationships between these components. Since the 1960s, a third subject, dynamic meteorology has emerged. It is generally useful for numerical simulations of weather and climate change, primarily using models of atmospheric approaches based entirely on the essential equations of dynamic meteorology. Other major subfields of climatology include bioclimatology and paleoclimatology.

Geothermal power trends are a promising technology as they have proven to be a clean and renewable resource that has provided energy in many forms from hot springs around the world for centuries. With the exception of certain areas with hot spring signs, you can feel the warmth of the earth wherever you go. Modern uses of geothermal energy include power generation, industrial heat source applications, and commercial and residential HVAC with geothermal heat pumps. The trend in geothermal power shows plants that utilize ground fluids obtained by drilling wells into geothermal reservoirs. Such plants present three main challenges when using geothermal energy to generate electricity.

1.High cost and risk of well exploration and drilling (approximately $10 million per well)
2.Low temperature (typically in the range of 80-300°C)
3.Disposal or re-injection of toxic brines from geothermal reservoirs

Whenever hot superheated steam is available directly from a geothermal source, it can be used in a steam turbine to generate electricity. However, this is not the case for low-temperature geothermal reservoirs. Cold ground fluids require the use of organic Rankine cycle (ORC) turbines with a heat exchange mechanism. This increases the cost of geothermal power plants compared to those using steam turbines, in addition to the cost of wells. However, the high cost of drilling wells can be avoided by choosing abandoned wells with depleted hydrocarbon reserves.
