Question: What is the role of renewable energy sources in powering machines?

Sample Answer (The AREA technique):

Answer: Renewable energy sources such as solar or wind power can play an important role in powering machines in the construction industry, reducing reliance on fossil fuels and mitigating environmental impacts.

Reason: The construction industry is a significant consumer of energy, and transitioning to renewable sources can help to reduce emissions and support sustainability goals.

Example: For instance, a construction site may use solar panels to power equipment such as lighting or air conditioning, while some manufacturers are developing electric or hybrid-powered machinery for construction use.

Alternative: However, it's important to recognize that the adoption of renewable energy sources may require significant investment or infrastructure changes, and it may be important to consider the economic and logistical feasibility of these options.
