REP Sustainability Practices & Environmental Impact 5

Question 1

Which concept describes designing products so that materials can be continuously cycled back into production, eliminating waste?

Accepted Answer

Circular economy

Answer

The circular economy model aims to keep materials in use for as long as possible through reuse, remanufacturing, and recycling, eliminating the concept of waste.

Question 2

What environmental benefit does demand response (DR) provide in a grid with high renewable penetration?

Accepted Answer

It reduces curtailment of renewable generation during overproduction periods

Answer

Demand response shifts electricity consumption to periods of high renewable output, reducing curtailment and improving the overall utilization of clean generation.

Question 3

Which factor most significantly determines a wind project's annual carbon offset potential?

Accepted Answer

The carbon intensity of the grid it displaces

Answer

The carbon offset per MWh generated depends on the emissions intensity of the displaced grid electricity, which varies significantly by region and fuel mix.

Question 4

The Social Cost of Carbon (SCC) is used in regulatory analysis primarily to:

Accepted Answer

Monetize the economic damages from emitting one additional ton of CO2

Answer

The SCC estimates the economic harm caused by releasing one additional metric ton of CO2, enabling cost-benefit analysis of emission reduction policies.

Question 5

Which practice is considered a key principle of 'just transition' in the context of decarbonizing the energy sector?

Accepted Answer

Ensuring fossil fuel workers and communities receive support and economic opportunities during the shift to clean energy

Answer

A just transition ensures that the move away from fossil fuels does not disproportionately burden workers and communities that depend on those industries.
