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

    Answer: High freshwater consumption in water-scarce areas

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

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

    Answer: Scope 2 — indirect emissions from purchased energy

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

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

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

    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.

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

    Answer: Curtailment during high-risk migration periods detected by radar

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

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

    Answer: Sustainable Biomass Program (SBP)

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

  6. The 'mitigation hierarchy' in environmental management follows which priority order?

    Answer: Avoid → Minimize → Restore → Offset

    Best practice requires first avoiding impacts, then minimizing unavoidable ones, restoring affected areas, and only then offsetting residual impacts.

  7. A Renewable Energy Certificate (REC) in the US represents:

    Answer: One megawatt-hour of electricity generated from a renewable source

    One REC is issued for each megawatt-hour of electricity generated and delivered to the grid from an eligible renewable energy source.
