Which of the following is NOT a challenge of renewable energy?
a) low impact on landscapes
b) economics
c) geography
d) intermittancy
a) Low impact on landscapes is not a challenge of renewable energy; it is actually a benefit compared to non-renewable sources like fossil fuels.
b) Economics can be a challenge when implementing renewable energy technologies, as they may require high initial investments and may not always be cost-competitive with conventional sources.
c) Geography can also be a challenge, as certain renewable energy sources (such as solar and wind power) may only be viable in certain regions.
d) Intermittency is a challenge of renewable energy, as sources like solar and wind power are dependent on weather conditions and may not always generate power on a consistent basis.
Therefore, the answer is a) low impact on landscapes.
