In pursuit of carbon neutrality, one of the key challenges lies in our continued reliance on fossil fuels. Fossil fuels, such as oil, natural gas, and coal, are finite resources that are predicted to deplete within several decades to a little over a century at our current consumption rates. Furthermore, the extraction and utilization of fossil fuels significantly contribute to environmental pollution, releasing greenhouse gases and harmful substances that exacerbate problems like global warming, acid rain, and respiratory diseases. To address these issues, a transition to renewable energy sources, as well as a reduction in energy consumption, is imperative.
Renewable energy sources, derived from natural elements like sunlight, wind, and water, offer an alternative to fossil fuels. They possess the advantage of being both sustainable and environmentally friendly, as they do not deplete like fossil fuels and have a lower ecological footprint. However, renewable energy does have its limitations, including intermittent energy production, higher costs, and the requirement for large-scale infrastructure. To foster the use of renewable energy, technological advancements and policy support are necessary.
Energy Consumption Reduction:
Supplementing the shift to renewable energy, curbing energy consumption is equally essential. Energy consumption reduction encompasses the practice of minimizing wasteful energy usage, such as conserving electricity, gas, water, and employing energy-efficient appliances. This approach not only reduces the consumption of fossil fuels but also offers economic benefits through cost savings.
Fossil fuels not only have detrimental environmental impacts but also pose a risk of future depletion. Therefore, transitioning to renewable energy and implementing measures to reduce energy consumption are crucial steps toward achieving a sustainable, carbon-neutral future.
Hydrogen, a versatile form of energy, has garnered significant attention as a means to reduce carbon dioxide emissions. It can be produced through various methods, offering a substantial advantage in terms of energy security. When produced domestically, it reduces the reliance on foreign energy sources, and when sourced internationally, it ensures accessibility from any location. Consequently, hydrogen contributes to a more stable energy supply. Moreover, hydrogen can be generated using renewable energy sources from water or through carbon capture in conjunction with fossil fuels. This makes it a viable option as a non-contributory energy source to global warming.
We enjoy the abundance of many goods, but it relies on the existence of factors such as environmental destruction. Abnormal heavy rainfall and record-breaking heat due to global warming have become major concerns. Issues like extreme heat, cold damage due to changes in ocean currents, diminishing tropical rainforests due to development, desertification, increasing wildfires, marine pollution, more powerful and destructive typhoons, and soaring food prices are all part of the environmental problems we face… the list goes on.
Particularly, the root cause of global warming is the burning of fossil fuels, which are hidden beneath the Earth’s surface, resulting in an increase in atmospheric carbon dioxide. Furthermore, our heavy dependence on fossil fuels, combined with the predicted depletion of these resources within this century, necessitates a swift shift to alternative methods that do not involve fossil fuels. This transition is becoming a global movement.
*Fossil fuels are fuels extracted from the Earth’s surface, such as coal, oil, and natural gas. They are not to be confused with actual fossils like dinosaur remains. The name “fossil fuels” is due to the fact that they take millions to hundreds of millions of years to form. Among fossil fuels, coal (of plant origin) can be extracted in solid form, oil (of animal origin) in liquid form, and natural gas (of animal origin) in gaseous form. Various geological conditions affect their formation over time.
One of the globally recognized choices for the energy shift ahead is hydrogen. This is because it is considered a crucial tool for achieving carbon neutrality.
To achieve carbon neutrality, substantial reductions in greenhouse gas emissions, primarily CO2, are necessary, along with the ability to absorb any remaining emissions. Hydrogen is anticipated to provide a feasible approach to achieve this goal due to its unique characteristics.
