How many percentage contribution of non renewable resources in climate change and global warming?5answers
Non-renewable resources significantly contribute to climate change and global warming. Oil, a non-renewable energy source, accounts for 37% of the world's energy consumption . Greenhouse gas emissions from burning non-renewable sources are a major cause of global warming, emphasizing the need to transition to renewable energy sources to combat climate change . Agriculture, a sector heavily reliant on non-renewable resources, contributes about 10%-12% of global anthropogenic greenhouse gas emissions, with direct livestock emissions alone causing 19% of total warming in 2010 . Additionally, the excessive use of non-renewable resources like fertilizers in agriculture contributes to greenhouse gas emissions, with agriculture responsible for 20% of the annual increase in anthropogenic emissions, mainly methane and nitrous oxide . Therefore, reducing the reliance on non-renewable resources is crucial in mitigating climate change and global warming.
What are the four primary benefits of using non-renewable energy sources?4answers
The four primary benefits of using non-renewable energy sources are: 1. Reduced pollutant emissions and fuel costs compared to large-scale conventional power plants, due to the smaller size of non-renewable distributed generators. This leads to improved efficiency and reliability of the power system .2. Improved security of critical loads and reduction in transmission losses, as electricity is generated closer to the load points .3. Non-renewable distributed generators can be used in areas with unpredictable renewable sources or where renewable energy technology is not mature enough for reliable operation .4. Non-renewable and economic growth increase carbon dioxide (CO2) emissions, while renewable energy consumption lessens CO2 emissions. Therefore, non-renewable energy sources can contribute to economic development, but renewable energy sources should be preferred to decrease CO2 emissions and improve environmental quality .
Is gold a renewable resource?5answers
Gold is not a renewable resource . It is a non-renewable resource that is extracted from the Earth through mining of ores . The extraction of gold depletes the reserves, and current production processes are depleting South Africa's gold reserves at an unsustainable rate . The depletion of gold reserves in South Africa is projected to reach a plateau by the mid-2020s . Therefore, it is important to consider the limited availability of gold and implement measures to prolong the lifespan of the gold reserves .
2.What are the environmental impacts of extracting and using non-renewable resources, and how can these impacts be mitigated?3answers
The extraction and use of non-renewable resources, such as coal, gas, and oil, have significant environmental impacts. These resources contribute to the emission of greenhouse gases, such as carbon dioxide and sulfur dioxide, which contribute to climate change and air pollution . Additionally, the extraction of these resources can lead to habitat destruction, water pollution, and the depletion of natural resources . However, these impacts can be mitigated through the use of renewable energy sources. Renewable energy, such as wind power, hydropower, photovoltaic, and geothermal energy, have lower water consumption, greenhouse gas emissions, and more favorable social impacts . By transitioning to renewable energy sources, we can reduce our reliance on non-renewable resources and minimize their negative environmental effects. Furthermore, promoting sustainable practices, such as controlling land use and promoting the exploration and use of renewable resources, can help mitigate the depletion of natural resources and lead to a more sustainable future .

Is energy related to the issue of transboundary river disputes?4answers
Energy is intricately linked to transboundary river disputes, as highlighted in the research papers. The management of water resources, especially in the context of transboundary waters, is crucial due to its connection to energy development . Cooperation in international river basins is often challenged by conflicts over water allocation, which is closely tied to the energy sector . Studies have shown that energy resources significantly impact the likelihood of militarized conflict, water-related conflicts, and cooperative river treaties between states . Additionally, the water-energy-food nexus plays a vital role in transboundary contexts, affecting water allocation and resource management, thus influencing the dynamics of transboundary river basins . Therefore, energy plays a significant role in transboundary river disputes, emphasizing the need for integrated approaches to address these complex challenges.
What are the key nutrients found in PHAs rich SCP?4answers
Polyhydroxyalkanoates (PHAs) rich single-cell protein (SCP) contains key nutrients such as nitrogen, phosphorus, iron, glucose, and salinity, which play crucial roles in the production of PHAs.

What do female and male entrepreneurs value in business accelerators?5answers
Female and male entrepreneurs value different aspects of business accelerators, reflecting their unique needs and challenges in the entrepreneurial ecosystem. Research indicates that women entrepreneurs place a higher value on knowledge transfer benefits, such as business skills education, compared to their male counterparts, who prioritize networking opportunities more . This difference is particularly pronounced in early-stage ventures, while in high-growth ventures, both genders equally value these services, with women placing greater emphasis on access to potential investors or funders . Additionally, female entrepreneurs benefit significantly from top accelerators, which help mitigate the challenges they face in acquiring venture financing and human capital, although they tend to fare worse in larger cohorts . Female founders also seek to enhance their entrepreneurial knowledge, network building, and self-efficacy more than male founders, although they report less progress in gaining legitimacy and accessing capital . Coaching services provided by accelerators are also valued differently; women emphasize the accessibility and guidance of these services more than men, reflecting differences in entrepreneurial learning and support needs . Despite these differences, both genders find accelerator programs valuable for improving business outcomes, with knowledge- and culture-related resources contributing significantly to their perceived value . Female entrepreneurs, however, are less likely to participate in accelerator programs initially, although their entrepreneurial self-efficacy and intentions improve over time, especially when they are part of teams with a higher proportion of women . The overall value of accelerators is also seen in their ability to provide smart capital, which includes both financial and non-financial resources, leading to significant value-added outcomes at both the individual and firm levels . This comprehensive support system helps level the playing field for first-time startup founders and female entrepreneurs, although gender disparities in benefits still exist .
