Offshore drilling is a common practice for obtaining supplies of oil. Which best describes a concern with using offshore drilling to obtain oil?

Offshore drilling can lead to oil spills and contamination of marine ecosystems, threatening the organisms living in these ecosystems.

Offshore drilling is not cost effective, requiring specialized equipment.

Offshore drilling is not very efficient, requiring a large amount of energy input to obtain a small amount of oil.

Offshore drilling produces oil that cannot be used directly; it must be further refined through several expensive processes.

Which method of energy transformation has the least potential environmental impact?

Photovoltaic cells transform solar energy into electrical energy.

Car motors transform electrical energy into mechanical energy.

Power plants transform nuclear energy into electrical energy

decision to choose energy resources that have less impact on the environment

decreased expense of fossil fuels

development of more expensive energy collection technologies

A family installs a new heating system in their home. Which is the most desirable result of the new heating system?

decreasing the amount of energy used

increasing the use of natural resources

increasing the time it takes to heat the home

Why do many communities use resources other than windmills to obtain energy?

Some areas have inconsistent winds.

Windmills make small amounts of energy.

Windmills are visual pollutants.

Which is an example of conservation of energy resources?

In the U.S., households are replacing their incandescent light bulbs with compact fluorescent light bulbs.

Niagara Falls, straddling both countries, produces electricity for Canada and the U.S.

Windmills in the Netherlands have been capturing wind power for more than 2,000 years.

How does coal compare to natural gas?

Coal is renewable, while natural gas is non-renewable.

Why is petroleum extracted from the earth described as a nonrenewable energy source?

It takes millions of years to form.

After drilling, it is made into gasoline fuel.
