1. What are the main differences between renewable and non-renewable resources?
Renewable means something can be replaced in a short time while on the other hand, non-renewable requires millions of years to develop. Renewable resources mainly reflect lower emission values and thus are part of sustainable development while on the other, side non-renewable resources increase the emission levels and thus have negative environmental impacts.
2. Why is renewable energy important for the future?
Renewable energy is essential to decrease the emission of greenhouse gases, improve energy security and address climate change. They are also sustainable because they reduce reliance on oil and gas and support the emergence of new climate technologies.
3. What are some examples of renewable resources?
Some of these are; solar energy, wind energy, hydropower, biomass, and geothermal energy. Photovoltaic cells are used in solar energy to convert the sun’s energy while wind power employs wind turbines. Hydropower involves the conversion of flowing water to electricity, biomass relies on organic materials to produce energy while geothermal energy is extracted from the earth’s heat.
4. What are the environmental impacts of non-renewable resources?
The sources include fossil fuels (coal, oil, natural gas), and nuclear and the associated negative effects are air and water pollution, loss of habitats and greenhouse gases. They cause negative environmental impacts, pollute the ecosystem, decrease the levels of biological diversity, and influence people’s health adversely.
5. How can individuals contribute to the use of renewable resources?
People can encourage the use of renewable energy by installing solar panels in houses, buying power from renewable sources, pushing for policies on the use of renewable energy, and observing power conservation. The utilisation of localised renewable energy projects and funding of green technology also reduces the shift of the dependency on energy.
6. What are the main types of non-renewable resources?
The main types of non-renewable resources are fossil fuels (coal, oil, and natural gas) and nuclear energy (derived from uranium). These resources exist in finite quantities and cannot be replenished within a human timescale.
7. What is meant by "peak oil" and how does it relate to non-renewable resources?
"Peak oil" refers to the point at which global oil production reaches its maximum rate, after which production will gradually decline. This concept highlights the finite nature of non-renewable resources and the eventual decline in their availability and production.
8. How do renewable and non-renewable resources differ in terms of energy density?
Non-renewable resources, particularly fossil fuels, generally have higher energy density, meaning they can produce more energy per unit volume or mass. Renewable resources often have lower energy density, requiring larger areas or volumes to produce equivalent amounts of energy.
9. What is the concept of "energy return on investment" (EROI) and how does it differ between renewable and non-renewable resources?
EROI is the ratio of energy produced to the energy required to extract, process, and deliver that energy. Non-renewable resources like oil historically had high EROI, but this is declining as easily accessible reserves are depleted. Renewable sources initially had lower EROI, but this is improving with technological advancements.
10. What are the challenges in transitioning from non-renewable to renewable energy sources?
Challenges include high initial costs for infrastructure, intermittency of some renewable sources (e.g., solar and wind), energy storage limitations, and resistance from established fossil fuel industries. Additionally, some renewable technologies require rare earth elements, which can have their own environmental impacts.
11. What are some examples of renewable energy sources?
Renewable energy sources include solar power, wind energy, hydroelectric power, geothermal energy, biomass, and tidal energy. These sources are naturally replenished and can be harnessed for electricity generation or other forms of energy use.
12. How does the use of renewable resources contribute to mitigating climate change?
Renewable resources produce significantly fewer greenhouse gas emissions compared to non-renewable sources. By replacing fossil fuels with renewable energy sources, we can reduce the amount of carbon dioxide and other greenhouse gases released into the atmosphere, helping to mitigate climate change.
13. What is the "energy transition" and why is it significant?
The energy transition refers to the global shift from fossil fuel-based systems of energy production and consumption to renewable energy sources. It's significant because it's crucial for reducing greenhouse gas emissions, mitigating climate change, and ensuring long-term energy sustainability.
14. How does the concept of "energy payback time" apply to renewable and non-renewable resources?
Energy payback time is the time required for an energy system to generate the same amount of energy used in its production. Renewable technologies like solar panels have a payback time of a few years, after which they produce net positive energy. Non-renewable resources don't have a traditional payback time as they don't regenerate within human timescales.
15. How do renewable and non-renewable resources compare in terms of water usage?

33. What is "energy poverty" and how might the shift from non-renewable to renewable resources affect it?
Energy poverty refers to lack of access to modern energy services. The shift to renewables could help alleviate energy poverty by providing decentralized, off-grid solutions in remote areas. However, the transition must be managed carefully to ensure energy remains affordable and accessible to all.
34. How do renewable and non-renewable resources compare in terms of their resilience to climate change impacts?
Renewable energy systems are generally more resilient to climate change impacts. For example, distributed solar and wind systems are less vulnerable to extreme weather events than centralized fossil fuel power plants. However, some renewables (e.g., hydropower) may be affected by changing precipitation patterns.
35. What is the "resource curse" and how does it relate to non-renewable resources?
The resource curse refers to the paradox that countries with an abundance of natural resources, particularly non-renewables like oil, often have less economic growth and worse development outcomes than countries with fewer natural resources. This is less applicable to renewable resources, which are more evenly distributed globally.
36. How do renewable and non-renewable resources differ in their potential for energy storage?
Non-renewable resources like fossil fuels are effectively a form of energy storage, easily transported and used on demand. Renewable energy often requires separate storage solutions (e.g., batteries, pumped hydro) to match supply with demand, which is an active area of technological development.
37. What is "energy return on carbon" (EROC) and how does it differ between renewable and non-renewable resources?
EROC measures the amount of energy produced per unit of carbon emissions. Renewable resources generally have a much higher EROC than non-renewables, producing more energy for each unit of carbon emitted over their lifecycle.
38. How do renewable and non-renewable resources compare in terms of their impact on air quality?
Non-renewable resources, particularly fossil fuels, often lead to significant air pollution through the release of particulate matter, sulfur dioxide, and nitrogen oxides. Renewable resources like solar and wind produce no direct air pollutants during operation, leading to improved air quality.
39. What is the concept of "energy democracy" and how does it relate to renewable vs. non-renewable resources?
Energy democracy refers to the idea of decentralizing energy production and giving communities more control over their energy systems. Renewable energy, particularly small-scale solar and wind, aligns well with this concept. Non-renewable resources typically involve centralized, corporate-controlled production.
40. How do renewable and non-renewable resources differ in their potential for circular economy practices?
Renewable energy technologies have greater potential for circular economy practices. For example, solar panels and wind turbines can be recycled at the end of their life. Non-renewable resources are inherently linear (extract-use-dispose), though some byproducts can be repurposed.
41. What is "energy intensity" and how does it relate to the use of renewable vs. non-renewable resources?
Energy intensity is the amount of energy used per unit of GDP. Transitioning from non-renewable to renewable resources often goes hand-in-hand with improving energy efficiency and reducing energy intensity, as it encourages the adoption of more efficient technologies and practices.
42. How do renewable and non-renewable resources compare in terms of their impact on human health?
Non-renewable resources, particularly fossil fuels, often have significant negative health impacts due to air and water pollution. Renewable resources generally have fewer direct health impacts, though there can be concerns with specific technologies (e.g., noise from wind turbines).
43. What is "energy colonialism" and how does it relate to renewable and non-renewable resources?
Energy colonialism refers to the exploitation of resources in less developed countries to meet the energy needs of more developed countries. This has historically been associated with non-renewable resources like oil, but there are concerns about similar patterns emerging with some renewable resources (e.g., lithium for batteries).
44. How do renewable and non-renewable resources differ in their vulnerability to cyber attacks?
Centralized non-renewable energy systems can be more vulnerable to large-scale cyber attacks. Distributed renewable energy systems, while not immune to cyber threats, often have built-in resilience due to their decentralized nature.
45. What is "energy justice" and how does it apply to the transition from non-renewable to renewable resources?

49. What is "energy sovereignty" and how does it relate to renewable vs. non-renewable resources?
Energy sovereignty refers to the right of people to make their own decisions about energy generation, distribution, and consumption. Renewable energy, particularly at the community scale, can enhance energy sovereignty. Non-renewable resources often involve dependence on external suppliers or large corporations.
50. How do renewable and non-renewable resources compare in terms of their impact on global geopolitical power dynamics?
Non-renewable resources, particularly oil, have historically shaped global power dynamics, with resource-rich nations wielding significant influence. The shift to renewables could redistribute global energy influence, potentially reducing the geopolitical power of traditional fossil fuel exporters.
51. What is "energy burden" and how might it be affected by the transition from non-renewable to renewable resources?
Energy burden refers to the percentage of household income spent on energy costs. The transition to renewables could reduce energy burden in the long term through lower operating costs, but care must be taken to manage transition costs and ensure energy remains affordable for all.
52. How do renewable and non-renewable resources differ in their potential for energy independence at the national level?
Renewable resources can enhance energy independence as they're locally available in most regions. Countries reliant on imported fossil fuels can reduce their dependence by developing domestic renewable resources. However, some renewable technologies require rare earth elements, which could create new forms of resource dependence.
53. How do renewable and non-renewable resources compare in terms of their scalability to meet global energy demands?
Non-renewable resources have historically been able to scale up quickly to meet growing energy demands, but are ultimately limited by finite supplies. Renewable resources have the theoretical potential to meet global energy demands many times over, but face challenges in rapid scaling due to infrastructure needs and intermittency issues.
54. What is "energy return on water invested" (EROWI) and how does it differ between renewable and non-renewable resources?
EROWI measures the amount of energy produced per unit of water used. Many non-renewable energy processes, particularly thermal power plants and hydraulic fracturing, have low EROWI. Some renewable sources like wind and solar photovoltaics have very high EROWI, while others like hydropower and some biofuels can have lower EROWI.
