Question 1

What makes hydropower a renewable energy source?

Accepted Answer

Hydropower is considered a renewable energy source because it utilises the natural water cycle to generate electricity. It harnesses the energy from flowing or falling water, which is continuously replenished by rainfall and snowmelt.

Question 2

How does hydropower compare to fossil fuels in terms of environmental impact?

Accepted Answer

Unlike fossil fuels, which release greenhouse gases and other pollutants into the atmosphere when burned, hydropower produces little to no emissions during operation. This makes it a cleaner alternative that significantly reduces the carbon footprint associated with energy generation.

Question 3

What is the lifespan of hydropower facilities?

Accepted Answer

Hydropower facilities generally have long lifespans, often exceeding 50 years with proper maintenance. Many can continue to operate for decades beyond their initial expected lifespan, contributing to their sustainability.

Question 4

Are hydropower facilities durable and sustainable?

Accepted Answer

Yes, hydropower facilities are designed to be durable, with robust infrastructure capable of withstanding various environmental conditions. Their sustainability is further enhanced by the ability to adapt and modernise technology to improve efficiency and reduce environmental impacts.

Question 5

What are the economic benefits of hydropower?

Accepted Answer

Hydropower can be cost-effective due to its low operational costs once established. Additionally, it creates jobs in construction, maintenance, and operation of facilities, contributing to local economies and providing a reliable source of energy at a relatively stable price.
