A:
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.
Q: What is meant by "peak oil" and how does it relate to non-renewable resources?
A:
"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.
Q: How do renewable and non-renewable resources differ in terms of energy density?
A:
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.
Q: What is the concept of "energy return on investment" (EROI) and how does it differ between renewable and non-renewable resources?
A:
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.
Q: What are the challenges in transitioning from non-renewable to renewable energy sources?
A:
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.
