Will renewable energy sources somehow stop global warming and renewable energy is important in energy and environmental sustainability?
Seria mais na questão de biocombustíveis, porque as energias renováveis não são 100%. Deste modo, deve haver um consórcio entre elas.
Renewable energy is energy produced from sources like the sun and wind that are naturally replenished and do not run out. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Sustainable energy, such as wind and solar energy, creates zero carbon emissions that can harm the atmosphere and contribute to global warming. It offsets the need for fossil fuels, which are actively increasing climate change and polluting our earth. We should use energy efficiency technologies (less energy use), use greening transportation means more efficient mass transportation systems, promote the use of renewable means natural source of energy (solar, wind, geothermal, etc) and reduces our use of fossil fuels especially carbon-intensive coals to reduce climate effects.Not only do they improve our health and economy, but also the environment. Using renewable energy over fossil fuels has a number of advantages. The most important advantage of renewable energy is that it puts an end to the production of greenhouse gases, most notably CO2 that causes global heating. Cheap electricity from renewable sources could provide 65 percent of the world's total electricity supply by 2030. It could decarbonize 90 percent of the power sector by 2050, massively cutting carbon emissions and helping to mitigate climate change. Derived from natural resources that are abundant and continuously replenished, renewable energy is key to a safer, cleaner, and sustainable world. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Renewable energy sources such as solar, wind, hydro, geothermal, and biomass can significantly contribute to sustainable development. We can reduce our reliance on finite and non-renewable resources like fossil fuels by harnessing these energy sources. They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases which cause climate change nor polluting emissions.
There is a great point in depending on renewable energy sources and reducing dependence on fossil fuel usage. However, what is see as red flags are the systems and materials used in their generation. are these systems and materials sustainable? what are their long-term effects on the environment? are they recyclable?
Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth are replenished by nature and emit little to no greenhouse gases or pollutants into the air. Renewable energy sources like wind energy, solar energy, and hydropower are sustainable forms of energy because they have a low environmental impact, are widely available, and are naturally replenished. For instance, when compared to coal-fired power plants, electricity from renewable energy sources emits between 90 and 99% less greenhouse gases (GHGs) and produces 70 to 90% less pollutants. These technologies also create jobs and stimulate economic growth, which is essential for sustainable development.Renewable energy plays a crucial role in making cities more sustainable by reducing air pollution, lowering carbon emissions, and improving the overall quality of life for urban residents. First of all, it is never going to end, we can use them for a long time and various purposes. Also, they generate energy in a large amount and efficiently. The most important benefit of renewable energy is that it is eco-friendly and don't contribute to environmental pollution. Renewable energy comes from sources that are constantly and naturally renewed (hence the name), such as wind power and solar power. Using renewable energy over fossil fuels has a number of advantages. The most important advantage of renewable energy is that it puts an end to the production of greenhouse gases, most notably CO2 that causes global heating. That's because renewable energy sources such as solar and wind doesn’t emit carbon dioxide and other greenhouse gases that contribute to global warming. Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels.
Availability of Renewable Energy Sources:
Concerning my research area, "biofuels," particularly fourth-generation biofuels, represent a promising frontier in the quest for sustainable energy solutions. These biofuels strive to outperform conventional sources by using cutting-edge feedstocks and optimisation techniques. Researchers are exploring innovative feedstocks, including non-food crops and waste materials, to diversify and enhance the sustainability of biofuel production. Additionally, engineered microorganisms through genetic engineering and synthetic biology are employed to optimise metabolic pathways, increasing biofuel yield and efficiency. Optimisation techniques extend beyond feedstock considerations and encompass improving overall process efficiency, downstream processing, and integrating systems for a more holistic and resource-efficient approach. Life cycle assessments play a crucial role in evaluating the environmental impact of fourth-generation biofuels, ensuring that the entire production process aligns with sustainability goals. As the focus shifts towards these advanced biofuels, their development holds great promise in contributing to a cleaner and more sustainable energy future, crucial for combating global warming.
