Why would installing a solar energy system be the preferred choice for a remote village?

• Solar energy is expensive and not cost-effective

• Solar panels require a lot of maintenance and are not reliable

• Solar energy is only available during the day and not suitable for all locations

• Solar energy is renewable, abundant, and environmentally friendly. It reduces electricity bills and can be used in remote areas.

A household wants to reduce its electricity bill. Which answer best describes how energy efficiency plays a role in achieving this goal?

• Energy efficiency is the use of technology that requires less energy to perform the same function, such as LED lighting instead of incandescent bulbs.

• Energy efficiency is not important in reducing energy consumption, and households should focus solely on reducing usage hours.

• Energy efficiency has no impact on the environment or energy consumption, and households should not consider it in their plans.

• Energy efficiency is the use of technology that requires more energy to perform the same function, such as using older appliances.
