Mirroring Policy from the Lens of Global Trade and Environmental Sustainability

Renewable energy has evolved over time. It incorporates various technologies to harness energy from natural resources like wind, sunlight, water, and geothermal heat. This integration aims to mitigate climate change, reduce greenhouse gas emissions, and promote sustainable development by leveraging these clean and renewable sources.

The future of sustainable energy is unfolding at an unprecedented pace, driven by the global shift towards a low-carbon economy. As the world transitions to cleaner, more efficient energy sources, groundbreaking advancements in renewable energy technology continue to accelerate.

The evolution of renewable energy systems are largely impacted by regulatory changes. The 1970s oil crisis sparked a surge of interest in alternative energy sources, laying the groundwork for the modern renewable energy landscape. Today, the industry continues to innovate, driven by the urgent need to address climate change and reduce greenhouse gas emissions.

Renewable Energy Trends 

Renewable energy is a driving force behind the sustainable energy revolution. It offers a cleaner, more efficient alternative to traditional fossil fuels. Some of the key trends to watch in renewable energy are:

1. Wind Energy: The energy demand is rapidly increasing, putting the world on the verge of a global energy crisis. Moreover, the extensive use of conventional energy sources is polluting the environment and causing global polluting. On the other hand, wind and other renewable energy sources are viable and clean alternatives to fossil fuels. Low operating cost and extensive availability make wind one of the most advantageous and effective renewable energy sources. Thus, larger, more efficient turbines are being.? developed, and offshore wind farms are becoming more prevalent.

2. Solar Energy: The solar industry is developing steadily all over the world. The high demand for energy while major energy source, fossil fuel is limited.
   It is a tool to develop economic status of developing countries and to sustain the lives of many underprivileged people.

3. Hydrokinetic Energy: Hydrokinetic energy harnesses the power of moving water, such as ocean tides and currents, to generate electricity. This renewable energy technology has the potential to provide a significant source of clean and predictable energy. With benefits like predictability, reliability, and low visual impact, hydrokinetic energy can contribute to a more sustainable energy future. However, it is important to address challenges like technological development, environmental impact, and cost. As the technology evolves, hydrokinetic energy is expected to play a growing role in the transition to a low–carbon economy.

Energy Storage Innovations 

The widespread adoption of renewable energy hinges on effective energy storage solutions, which ensure a stable and reliable power supply. Breakthroughs in this field are revolutionizing the way we store energy with key innovations including:

1. Hydrogen Fuel Cells: A fuel cell-based energy storage system allows separation of power conversion and energy storage. It functions enabling each function to be individually optimized for performance, cost or other installation factors. This ability to separately optimize each element of an energy storage system can provide significant benefits for many applications. Various fuel cell/electrolyzer-based energy storage concepts and applications that employ these concepts using hydrogen are examined here.

2. Battery Technology: The rapid advancement of battery technology stands as a cornerstone in reshaping the landscape of transportation and energy storage systems..

3. Pumped Hydro Storage: The use of macro storage technologies has been widely studied in the literature with pumped hydro energy storage (PHES). It emerges as the main option for its high stability and low environmental impact. Additionally, in recent years researchers have focused on combining a micro storage system with a photovoltaic and/or wind system that serves to increase self-consumption.

Sustainable Energy Innovations 

Effective energy storage is crucial for the widespread adoption of renewable energy. It ensures a stable and reliable power supply despite the intermittent nature of solar and wind energy. Some of them include: 

1. Floating Wind Turbines: The global floating offshore wind energy industry is rapidly maturing. It has several technologies installed at pilot and demonstration scales. As the industry progresses to full array-scale deployments, the optimization of marine activities related to installation, operation and construction construction maintenance, and decommissioning presents a significant opportunity for cost reduction. Floating wind turbines are installed in waters, opening up new areas for offshore wind development.

2. Advanced Geothermal Systems: the Advanced Energy Storage systems provides an innovative approach that can help supply energy demand at-large scales. They operate by injection of heat collected from various sources into an existing well in low temperature subsurface to create an artificial and sustainable well. Also, they can tap into heat deeper in the Earth’s crust, providing a promising source of renewable energy.

3. Bifacial  Solar Panels: Bifacial solar photovoltaics (PV) is a promising mature technology that  increases the production of electricity per square meter of PV module through the light absorption from the albedo. Bifacial tsolar panels can generate electricity from both the front and back sides of the panel, increasing energy output.

Global Actions: Regions Leading The Change

Some regions are pioneering the transition to sustainable energy through innovative policies and initiatives. Examples include:

European Union: The European Union has established bold objectives5: to cut down on greenhouse gas emissions and boost renewable tenergy output. The Real for Europe seeks to transform Europe into the world’s first climate-neutral continent by 2050.

United Kingdom: The UK has established a goal to reach net-zero emissions by 2050 and is actively supporting the growth of renewable energy sources, including offshore wind and solar power, through targeted policies and initiatives.

Germany: The Energiewende program aims to decrease greenhouse gases and expand clean energy production.

United States: In the US, state-level renewable portfolio standards and federal tax incentives are driving the growth of renewable energy, with pioneers like California and Hawaii pushing the boundaries with ambitious clean energy targets.

Policy Directions

Countries and regions are pursuing several key policy strategies to drive the shift to sustainable energy, including:

1. Tax Credits: Tax credits can incentivize sustainable energy projects by lowering development costs, helping countries achieve their clean energy goals.their electricity from renewable sources.

2. Renewable Portfolio Standards:  Renewable Portfolio Standards (RPS) mandate that utilities produce a specified percentage of electricity from renewable sources like solar, wind, or hydroelectric power.

3. Research and Development: Governments are funding research and development to advance innovative sustainable energy technologies and enhance the performance of current ones.

4. Grid Modernization: Upgrading the grid can facilitate the seamless integration of renewable energy sources, ensuring a stable and efficient energy supply.

Sustainable energy’s future is bright, driven by rapid advancements in renewables, storage, and smart grids. As the world transitions to a low-carbon economy, these innovations will play a significant role.
