Energy Conservation

Which is NOT a way to conserve energy?

• Using a desktop computer rather than a laptop
• Consolidating errands while to make fewer car tips
• Replacing incandescent bulbs with compact fluorescent bulbs
• Using a power strip for electronics
• Lowering thermostats during cold months

A tiered rate system for electricity use charges customers

• increasingly higher rates as the system uses more resources that are not renewable.
• different rates based on the square footage of the dwelling or business.
• lower rates for the first increments of electricity used and higher rates as usage rises.
• different rates based on peak usage times.
• according to their income status.
