what is renewable energy Flashcards
1
Q
advantage of renewable energy
A
renewable energy resources are sustainable as they can be replenished constantly
they produce little carbon dioxide and fewer air pollutants. this helps minimise the impacts of global warming and air pollution
no extraction activities are involved to obtain renewable energy resources. soil erosion and land degradation are thus avoided
2
Q
limitations of renewable energy
A
most renewable energy is site-specific, not all places are suitable for development. for instance, wind farms need a windy location
the amount of electricity generated varies with weather conditions
lower electricity output may not meet the demand for economic development
the start-up cost is relatively high as compared to the use of fossil fuels
