See the concepts below

Explanation:

Government fuel efficiency standards for vehicles have been generally slightly low for many years. Between the years 1973-1985 the average fuel efficiency for new vehicles sold in the U.S. increase considerable, because the government create new laws for the corporate average fuel economy.

Gasoline is much higher then is paid because the costs associated to the pollution control and other things liket military protection of oil supplies in some areas, time wasted, and costs associated from air and water pollution in the form of higher medical costs.  

Fee-bate represent a program in "which buyers of fuel inefficient cars would pay a high fee, and the resulting revenue would be given to buyers of efficient cars as rebates "

Hybrid: is an energy efficient gasoline-electric car. "Use a small traditional gasoline-powered engine and a battery-powered electric motor used to provide the energy needed for acceleration and power".

Plug-in hybrid: is defined as "a hybrid with a second and more powerful battery that can be plugged into an electrical outlet and recharged anytime".

Fuel cell motor: "is more efficient thn combustion engines, having no moving parts, requiring little maintenance, and use hydrogen gas as a fuel to produce electricity"

Living roofs:  "green roof or living roofs, also known as a grass roof or living roof, is a growing trend. Architects can put roots down in the most expected of places and is a roof that is covered in plants, which reduces stormwater run-off and lowers cooling costs".

And the importance of white or light colored roof is that reflect away heat rays from the sun, and we have less heat absorption.

LED bulbs "require much less wattage than CFL or Incandescent light bulbs, and that's the reason why LEDs are more energy-efficient and longer lasting than their competitors".

A compact fluorescent (CFL) "eliminates three-fourths of the mercury pollution of a traditional light bulb: 3.3 mg versus 13.6 mg and using CFLs reduces the amount of mercury outside to the air and surface water and that's to important to the environment"

Green building, is a sustainable design, and is a "method to increase the efficiency using the energy from the buildings, water, other materials, and this techinique reduce impacts on human activities and environment".

List six ways in which you can save energy where you live.

Adjust your day-to-day behaviors reducing the amount of energy consumed.

Replace your light bulbs with LED lights.

Use smart power strips, removing the vampire concumption.

Reduce the water heating expenses.

Change the system of energy of your house

Use other types of energies to satisfy the requirments.

Give three reasons why we waste so much energy.
