REP Sustainability Practices & Environmental Impact 4

Question 1

Which water-related environmental concern is most significant for concentrating solar power (CSP) plants using wet cooling in arid regions?

Accepted Answer

High freshwater consumption in water-scarce areas

Answer

Wet-cooled CSP plants consume large volumes of water for cooling, which is a critical concern in desert environments where water resources are scarce.

Question 2

Under the EPA's Scope 1, 2, 3 emissions framework, a company's electricity purchases from the grid are categorized as:

Accepted Answer

Scope 2 — indirect emissions from purchased energy

Answer

Scope 2 emissions cover indirect GHG emissions from the generation of purchased electricity, heat, or steam consumed by a company.

Question 3

What is the 'energy payback period' for a solar PV system?

Accepted Answer

Time for cumulative energy output to equal the energy used in manufacturing and installation

Answer

The energy payback period is the time required for a PV system to generate an amount of energy equal to what was consumed during its production and installation.

Question 4

Avian mortality from wind turbines is most effectively reduced through which mitigation strategy?

Accepted Answer

Curtailment during high-risk migration periods detected by radar

Answer

Radar-triggered curtailment, which temporarily halts turbines when large bird flocks are detected, has demonstrated significant reductions in avian mortality.

Question 5

Which international certification verifies that biomass feedstocks are sourced sustainably and meet environmental and social criteria?

Accepted Answer

Sustainable Biomass Program (SBP)

Answer

The Sustainable Biomass Program (SBP) provides a certification framework ensuring woody biomass for energy meets sustainability, legality, and carbon criteria.
