Worked Solution & Example Answer:The photograph shows a dam and hydroelectric station on an Irish river - Junior Cycle Geography - Question Question 1 - 2006
Step 1
Name one economic benefit and one environmental benefit of hydroelectricity.
Answer
An economic benefit of hydroelectricity is that it provides a clean source of power, helping to reduce reliance on fossil fuels. Additionally, it creates job opportunities when building and maintaining the power stations.
An environmental benefit is that hydroelectric power generation does not produce harmful emissions, contributing to cleaner air and a reduction in pollution.
Step 2
Outline two objections which might be made to the development of a hydroelectric scheme such as the one shown.
Answer
One objection is that the construction of dams can destroy local ecosystems and habitats, adversely affecting fish populations, such as salmon, which cannot migrate upstream.
Another objection is that such developments can lead to flooding of surrounding farmland, displacing communities and affecting agricultural production.
