Harvesting Energy from the Sun

The sun is crucial as a source of energy for living things, including plants, animals, and humans. It is an abundant, free, and inexhaustible source of energy, except at the time of judgment. The word "sun" is mentioned 25 times in the Quran and is the name of one of the chapters mentioned by Allah in the Quran. This suggests that Allah intended to signal that there is something for humans to explore through the sun (Asy-Syams).

An American Muslim and environmental activist, Ibrahim Abdul Matin (2012), in his book Green Deen: What Islam Teaches about Protecting the Planet, refers to renewable energy as energy from heaven. According to him, energy from heaven originates from above, meaning it is not extracted from the earth and is renewable. "Extraction causes imbalance (causes climate change), while energy from above is like energy from heaven." 

By 2024, solar power production will reach 453 GW. With wind power generation added, the two sources will account for 97.5% of the total renewable energy, making them the dominant renewable energy source. With wind power production reaching 114 GW, or about a quarter (25%) of solar power, solar energy is crucial due to its competitive cost and rapid development. China is currently the world's leading producer of solar PV. 

China's ambition is to build a "solar great wall" designed to meet Beijing's energy needs. The multi-year project, expected to be completed by 2030, will be 400 kilometers (250 miles) long, 5 kilometers (3 miles) wide, and reach a maximum generating capacity of 100 gigawatts. Currently, the project is reported to have reached a capacity of 5.4 gigawatts. Since 2024, China has led the world in electricity production from solar panels. As of June 2024, China led the world in operating solar power generation capacity with 386,875 megawatts, representing about 51 percent of the global total, according to Global Energy Monitor's Global Solar Power Tracker. The United States ranked second with 79,364 megawatts (11 percent), followed by India with 53,114 megawatts (7 percent). 

Even Elon Musk has been saying it for years, and it's something solar energy pioneers already know: the sun has enough energy to meet all our energy needs. The problem lies not only in ensuring that people have the technology to harvest the sun through solar panels, but in cities and urban centers, one of the biggest issues is storage and what to do with excess energy when the sun is shining, which is why batteries for storing that energy are so important. Consumers and businesses, when possible, typically feed energy back into the grid, where they receive cash or credits for their contribution.

But harvesting solar energy is of course not only done with solar panels (solar PV). Trees or plants also harvest solar energy and convert it into other energy sources, namely biomass-based. Renewable energy sources derived from plants (bio-energy) are also in line with QS. Yaasin (36): 80. To produce these energy sources, whether such as wood, fruit, seeds or other parts of the plant, plants carry out photosynthesis. In addition to water and carbon dioxide (CO2), this photosynthesis process requires sunlight. 

Plants, through the process of photosynthesis, store energy from the sun in the form of biomass, and this is likened to a battery. This green battery of plants can be used as a very large energy source; for more details, read here. Unlike harvesting solar energy with solar panels (solar PV), which is highly dependent on the weather, resulting in intermittent electricity supply, or likewise with wind, which sometimes does not blow, biomass energy from plants will produce stable electricity. Once converted into biomass and harvested as an energy source, the energy will always be available. And to generate electricity from solar panels (solar PV) to overcome weather problems and prevent intermittent electricity supply, very large batteries are required, and currently not available. 

Indonesia is believed to be a tropical country, the biomass heaven. This needs to be translated into more concrete terms so that it can be understood, implemented, proven, and optimally utilized. Its potential is immense and should be used to support the well-being of its people. The simple diagram below illustrates the many possibilities in this tropical "biomass heaven." 

The availability of raw materials is a vital and absolute must for various biomass processing processes to be carried out and be sustainable. On the other hand, there is a huge potential for land that can be utilized for this purpose, amounting to tens of millions of hectares, namely critical land / marginal land, dry land and post-mining land (coal mines, tin mines, nickel mines, copper mines, gold mines and so on). In more detail, it is estimated that for critical / marginal land reaches 24.3 million hectares (Times Indonesia, 2017), while dry land reaches 122.1 million ha consisting of dry acid land covering 108.8 million ha and dry climate dry land covering 13.3 million ha and post-mining damaged land reaching 8 million hectares. Energy plantations or biomass plantations need to be created in these areas and can even be used for various food crops. In fact, currently there are plant species that can only be economically viable in these lands. 

The Quran, as a source of knowledge, teaches how to obtain renewable and sustainable energy that will save humanity and the earth. By delving into and studying the verses of the Quran in detail, we will uncover various important guidance for navigating life. This should motivate and inspire humans, especially Muslims, to conduct beneficial scientific research. Applying existing resources, in line with Quranic guidance, and developing and refining efforts to harvest solar energy must continue. Furthermore, the Quran provides a solid moral, ethical, and legal basis for the balanced and responsible development of science and technology. 

The Quran explicitly emphasizes the importance of knowledge. This is evident in the first verses revealed to the Prophet Muhammad (peace be upon him), which contain the command to read, and the story of Adam being taught the names of all things, signifying humanity's superiority through knowledge. The Quran encourages travel and observation, thus opening minds to scientific discoveries. The Quran provides guidelines to ensure that the knowledge developed is used for good and does not conflict with moral values.

The Urgency of a Justice Energy Transition part 2

The sun is the source of energy for all living things on Earth. It is an abundant, free, and inexhaustible source of energy, except at the end of the world. The word "sun" is mentioned 25 times in the Quran and is one of the chapters mentioned by Allah in the Quran. This indicates that Allah wants to signal that there is something that humans need to explore through the sun or asy-syams. Utilizing the sun for electricity production has attracted the attention and focus of scientists worldwide. And Muslim scientists, in particular, with this divine motivation from the Quran, should be motivated and driven to research and implement it. This driving force is especially strong in the era of decarbonization, or the substitution of fossil fuels for renewable energy to address climate change and global warming.

Ibrahim Abdul Matin (2012), a Muslim from the United States (US) and environmental activist, in his book Green Deen: What Islam Teaches about Protecting the Planet, refers to renewable energy as energy from heaven. According to him, energy from heaven comes from above, meaning it is not extracted from the earth and is renewable. "Extraction causes imbalance (causes climate change), while energy from above is like energy from heaven."

In practice, solar energy has been widely utilized to generate electricity. Humanity is challenged to develop the best science and technology to maximize the harvest and utilization of solar energy. Technology and supporting infrastructure have even been widely used as a powerful weapon to address climate change and global warming. However, in practice, not all implementations of this technology have been successful and yield significant financial returns. The Ivanpah project in California, USA, is one such project. The electricity production project, utilizing solar heat with CSP (Concentrated Solar Plant) technology, failed to achieve its business objectives and lost out to the more accessible and affordable solar PV (photovoltaic) technology.

CSP technology, or solar thermal technology, uses mirrors to concentrate sunlight, generating heat to produce steam to drive turbines, generating electricity. Meanwhile, in solar PV, the solar panels will directly absorb sunlight using semiconductor materials. The Ivanpah project, which cost 2.2 billion USD (more than 35 trillion rupiah), became a bitter pill for the development of solar energy utilization technology. The Pacific Gas & Electric (PG&E) company, as the main buyer, even terminated its long-term contract (PPA / Power Purchase Agreement) for purchasing electricity from the previous 14-year agreement from the Ivanpah project, forcing 2 of its 3 units to shut down. This was because the Ivanpah project with CSP technology was unable to produce adequate performance or performance, even for its operations still with additional natural gas.

For solar PV power generation, China is currently the world's leader or largest producer of solar power. China's ambition is to build a "solar great wall" designed to meet Beijing's energy needs. The multi-year project, estimated to be completed in 2030, will be 400 kilometers (250 miles) long, 5 kilometers (3 miles) wide, and reach a maximum generating capacity of 100 gigawatts. Currently, the project is reported to have reached a capacity of 5.4 gigawatts. Since 2024, China has led the world in electricity production from solar panels. As of June 2024, China led the world in operating solar power generation capacity with 386,875 megawatts, representing about 51 percent of the global total, according to Global Energy Monitor's Global Solar Power Tracker. The United States ranked second with 79,364 megawatts (11 percent), followed by India with 53,114 megawatts (7 percent).

In the coming decades, large-capacity batteries, up to several MW, are predicted to be widely used in solar PV power plants. These batteries will enable solar PV power plants to continue supplying electricity at night or on cloudy days. Research and development of these batteries is ongoing, and it would be preferable if some of the battery components were derived from renewable sources, such as electrodes made from biographite (which is made from biochar), rather than synthetic graphite derived from fossil fuels, which are currently dominated by China.

Climate and weather factors significantly influence the operation of solar PV power plants. When weather conditions, such as cloudy days without sunlight, occur, electricity production is hampered or intermittent. Furthermore, the use of large-capacity batteries is not yet available and requires considerable time. This is why renewable energy sources that are ready at any time and are not affected by the weather are highly needed. Biomass energy sources such as wood pellets are one such energy source. Renewable energy sources derived from plants (bio-energy) are also in line with QS. Yaasin (36): 80. To produce these energy sources, whether from wood, fruit, seeds, or other parts of the plant, plants carry out photosynthesis. In addition to water and carbon dioxide (CO2), this photosynthesis process requires sunlight. The sun is very important as an energy source for living things, especially for plants. Renewable energy sources from biomass (bio-energy) are like "green batteries" that have great potential as a means of capturing solar energy, and for more details, please read here.
