A school replaces 60-watt incandescent light bulbs with 13- watt compact fluorescent bulbs in each classroom. If there are no other changes in how the lights are used, how will the electricity use compare, after changing the light bulbs?

The school will use less electricity after the change.

The school will use more electricity after the change.

The school will create more waste than before the change to compact fluorescent light bulbs.

The school will need more light bulbs to generate the same amount of light as before the change.

Though hydroelectric energy provides 58% of the Unites States' renewable energy and has many advantages, one disadvantage of this form of energy is that it

requires building a dam, destroying nearby ecosystems.

is costly to maintain, reducing the amount of energy it can produce.

must burn plant matter, which disrupts the wind needed to produce renewable energy.

must use Earth's internal heat, which counteracts the needed gravitational force.
