REP Environmental Impacts of Renewables 5

Question 1

What is the purpose of an Environmental Impact Statement (EIS) for a large renewable energy project?

Accepted Answer

To systematically analyze potential environmental effects and identify mitigation measures

Answer

An EIS, required under NEPA, documents direct, indirect, and cumulative environmental impacts and evaluates alternatives, helping decision-makers weigh environmental costs against project benefits.

Question 2

Which water use strategy in concentrating solar power (CSP) plants has the greatest potential to reduce environmental impact in arid regions?

Accepted Answer

Switching from wet cooling towers to dry (air-cooled) condensers

Answer

Dry cooling eliminates the large volumes of water evaporated by wet cooling towers, making CSP far more viable and environmentally compatible in water-scarce desert environments.

Question 3

What is 'habitat fragmentation' and how do utility-scale solar projects contribute to it?

Accepted Answer

Dividing contiguous natural habitats into smaller, isolated patches with fences and access roads

Answer

Solar projects introduce fencing, roads, and cleared areas that break up continuous habitat, reducing genetic exchange between populations and making species more vulnerable to local extinction.

Question 4

Which migratory bird group faces the highest mortality risk from concentrated solar power (CSP) tower facilities specifically?

Accepted Answer

Aerial insectivores and waterbirds attracted to the 'lake effect'

Answer

CSP power tower 'solar flux' zones superheat the air around the central receiver, killing insects that attract insect-eating birds and waterbirds confused by glare that resembles water surfaces.

Question 5

How does the 'green paradox' apply to accelerating renewable energy deployment?

Accepted Answer

Building more renewables reduces electricity prices, which can increase total energy consumption

Answer

Lower energy prices driven by renewable abundance can stimulate higher overall electricity demand (the rebound effect), potentially offsetting some of the carbon savings from replacing fossil generation.
