Question

Amy’s electric bill is far too expensive. To save costs, she decides to:

a) Switch to energy-efficient appliances
b) Negotiate a lower electricity rate
c) Install solar panels
d) Use fewer electronic devices

Answer 1

To save costs on the electric bill, Amy can switch to energy-efficient appliances, negotiate a lower electricity rate, install solar panels, and use fewer electronic devices.

Step-by-step explanation:

The motivation to save energy has become more compelling with its ever-increasing price. Armed with the knowledge that energy consumed is the product of power and time, you can estimate costs for yourself and make the necessary value judgments about where to save energy. Either power or time must be reduced. It is most cost-effective to limit the use of high-power devices that normally operate for long periods of time, such as water heaters and air conditioners. This would not include relatively high power devices like toasters, because they are on only a few minutes per day. It would also not include electric clocks, in spite of their 24-hour-per-day usage, because they are very low power devices. It is sometimes possible to use devices that have greater efficiencies-that is, devices that consume less power to accomplish the same task. One example is the compact fluorescent light bulb, which produces over four times more light per watt of power consumed than its incandescent cousin.
