INTRODUCTION

Wind and solar energy forms are perhaps the most important natural sources of energy in the future economy.

Therefore, the optimization of such resources becomes the key goal, as the society becomes more involved in the process of using clean energy.

Optimization of wind and solar power generation is not only done in terms of making energy cheaper, but also in terms of reducing harm on the ecosphere, thereby making renewables even more realistic for mass application.

In this regard, advances in the contemporary technologies are delightful, challenging the way wind and solar power are collected, stored, and supplied to the market, to ensure that the ever-growing global energy demands are met effectively and with enhanced reliability.

Advances in Wind Energy

There are new breakthroughs in wind energy conversion which have greatly improved the resource and viability of wind energy conversion.

Among the improvements that have been made is usually the betterment of the speculations of wind turbines.

The evolving generation turbines are now adopting modularity in their construction to ease transportation, and ease of repair when necessary, thus cutting on periods of breakdown and repair.

These turbines can also be designed with modularity in the various components, and therefore may be easily fitted depending on the operation requirements.

Newer inventions such as the airborne wind turbines (AWTs), that are designed to work way above the ground, that is 1000 feet in the air, where wind is both more forceful and reliable.

This innovation strives to harness wind energy in a more efficient way, and in areas that are not suitable for conventional wind turbines.

Another encouraging development is floating wind energy. In their standard design,  the offshore wind turbines are grounded to the sea bed, and hence, their applicability is restrained to water that is shallow.

Nevertheless, FLOATING WIND TURBINES can be installed at significantly greater water depths – that is, to huge wind resources that have previously been unavailable.

Some of the development in this area has been recognized by the U. S. Department of Energy FLOWIN Prize, such as the Wind Float platform which has enhanced operation at deep water by incorporating a damping system.

These floating platforms are also in sections and can be built alongside, and towed to site to be joined together, thus making it easy to manufacture as well as install.

This innovation is important as it provides potential for improvement of offshore wind resources, where seabed condition or water depth preclude use of conventional turbines.

Innovations in Solar Energy

Solar energy, it can be seen that technological progress is now starting to be reflected by a great boost in the effectiveness of solar cells.

One of such developments is utilization of perovskite materials, where they have been incorporated in tandem solar cells.

It integrates the faith silicon with perovskite layers, which absorb more of the solar’s spectrum and therefore boosts the conversion efficiency of the relative energy.

Additionally, bifacial solar panels, which can capture sunlight from both sides, are being deployed more frequently, especially in areas with high albedo (reflectivity) like deserts, further boosting energy output. (https://www.ft.com/content/b7b7f8a0-cb06-11e7-8536-d321d0d897a3).

Another advanced technology at the cutting-edge, is that of the concentrated solar power (CSP,) which uses mirrors to focus the sun’s rays on a receiver that in turn warms up a fluid, thereby creating steam which powers a turbine.

CSP systems are capable of storing thermal energy, hence can produce electricity even during limited sunshine.

This capability makes CSP a potential solution for constant and reliable electricity supply, which can be used to support the fluctuating renewable power, such as wind and photovoltaic solar.

And as such, these technologies have the ability to make solar energy a more reliable and efficient part of global energy inventory.

These advances in wind and solar devices are entirely beneficial in the leadership of fresh renewable energies and moderation of fossil outcomes. They help in  making the existing renewable energy sources more efficient and open new areas to tap this clean source of energy.

Renewable Energy Storage

Energy storage solutions are vital to achieving the highest level of reliability coupled with much higher efficiency of wind and solar energy. Because the generated energy is irregular – solar energy can only be generated when the sun is up, and the wind energy during the windy periods – storage enables the excess energy produced during the day to be stored in a suitable technology to be used when needed.

This efficiency is brought about by recent innovative research in energy storage technologies.

Lithium-ion batteries currently retain the highest market share owing to their minimal energy density as well as the constantly declining prices.

However, there are new types of batteries that are in the development stages such as flow batteries and solid-state batteries that have far better features such as better cycle life and better safety features.

Of the various types of batteries, flow batteries are recently experiencing high levels of adoption for large-scale energy storage applications, because of their flexibility in scaling up power output through scaling up energy capacity and therefore suitable for utility scale applications.

Hence, hydrogen storage forms part of the assemblage that is currently being recognized in the renewable energy system.

Hydrogen can be produced using excess renewable energy through electrolysis and stored for long periods, providing a versatile option for both energy storage and fuel.

These innovations in energy storage are not only improving the efficiency of renewable energy utilization, but are also essential for the broader transition to a low-carbon economy, ensuring that renewable energy can be reliably integrated into the grid.

Smart Grids and Energy Management

The technological advancement in the distribution of electricity through smart grids is challenging, not only the traditional approach in the distribution of energy, but especially in the case of renewable energy.

Such sophisticated systems involve the use of digital technology to regulate the use of power, the supply of power, and the flow of power, from various sources such as renewable power supplies.

Integration of smart grid in renewable energy increases the effectiveness by creating an intelligent network of producers, consumers, and the grid.

Such a dynamic enables a much more effective demand response, where the consumers are able to flexibly use energy depending on their availability and price.

For example, in periods of excessive generation of renewable energy, smart grids can communicate to consumers to use more energy, and hence maximize the utilization of renewable energy.

Smart grids also include energy management systems that are also rather influential. Such systems can predict the energy demand; they can control the energy storage, and also can include electric cars into the grid, utilizing their batteries as storage.

This level of integration and optimization is essential for reducing energy waste and ensuring that renewable energy is used as effectively as possible. (https://www.iea.org/reports/technology-roadmap-smart-grids) (https://energy.ec.europa.eu/topics/research-and-technology/energy-storage_en).

Over time, these technologies shall be responsible for the global enhancement of efficiency and sustainability of energy, making the renewable energy sources more reliable.

Case Studies:

The Following Are Some Of The Examples Of Renewable Energy Efficiency:

The application of modern technologies in renewable energy for practical uses have further shown an instance of enhanced efficiency, especially in wind and solar energy.

A good example is the Gemini Solar Project in Nevada, which will be one of the largest solar power facilities in America after construction.

This project entails the use of high efficiency PV panels and storage, to produce the energy output in those times when demand is high.

The case is a showcase of innovative technologies of solar energy, and energy storage where modern innovations are key to achieving higher efficiency and reliability.

Concerning wind energy, one of the most distinguished projects is the Hywind Scotland – the world’s first floating wind farm.

This project is situated in the ocean and aims to capture wind energy for which it uses wind turbines that cannot be installed in deep waters.

It is worthy of note that while they have established that Hywind Scotland is a credible model for floating wind systems, the door has been opened for future offshore wind construction in areas of similar geographic characteristics. https://www.weforum.org/agenda/2022/03/solar-wind-power-renewable-energy-climate-change/).

The above examples showed that additional efficiency of technology that is used in wind and solar power is not only an increase in capacity, but also an opportunity to expand the use of renewable energy sources in different climatic conditions.

Conclusion

Sophisticated technologies continue to improve the extracting process of wind and solar energy; these sources of energy are becoming more usable by the public.

New concepts in turbines, floating wind farms, improved solar panel technology, coupled with smart energy storage, and smart grids are putting the energy world on a pedestal for a green energy future.

These technologies will only continue to grow in importance as we look towards the transition away from fossil fuels and combating climate change. Thus, the further development of renewable energy sources is quite possible, and constant creation contributes to the prospect of a bright future on the planet.
