Energy Efficiency

The Empire State Building consumes enough energy in an hour to keep an average light bulb burning for how long?
  • 1 year
  • 5 years
  • 50 years
  • Over 100 years
Over 100 years

Correct

Our energy needs at the Empire State Building are great. But through increased energy efficiency, we’re reducing our usage and saving money.

Incorrect

We use enough energy to keep a bulb burning for over 100 years, but through increased energy efficiency, we’re reducing our usage and saving money.
Over 15 years, the emission reduction from the Empire State Building’s energy-efficiency projects will be the same as taking how many cars off the road?
  • 200 cars
  • 2,000 cars
  • 20,000 cars
  • One SUV
20,000 cars

Correct

Our efforts will cut carbon emissions by 105,000 metric tons over fifteen years. That’s like taking 20,000 cars off the road.

What uses the most energy in the average home?
  • Heating
  • Lighting
  • The TV
  • Your electric toothbrush
Heating

Correct

On average, heating accounts for more than 40% of home energy use. You may be able to reduce your usage and lower your utility bills by upgrading your insulation and plugging air leaks around windows and doors.

If every American home replaced one standard light bulb with a compact fluorescent bulb, the reduction in carbon emissions would be like taking how many cars off the road?
  • 8,000 cars
  • 80,000 cars
  • 800,000 cars
  • 8 million cars
800,000 cars

Correct

If every home in America replaces just one light bulb with a compact fluorescent bulb, it would save about $600 million a year in energy costs. This is equivalent to taking more than 800,000 cars off the road.

As part of the Empire State ReBuilding Program, all 68 of the building’s passenger elevators were upgraded in 2011. The elevators are now:
  • Faster
  • Smoother
  • More energy efficient
  • All of the above
All of the above

Correct

Our new elevators have regenerative brakes that harvest the energy from braking and return it to the building’s electrical grid. That makes the elevators up to 30% more efficient. They
also are able to transport passengers 20 to 40% faster.

What is the most efficient type of lighting?
  • Compact fluorescent bulbs
  • Incandescent bulbs
  • LED lights
  • The Sun
The Sun

Correct

Although compact fluorescent light bulbs are much more efficient than traditional incandescent bulbs, nothing beats the sun for efficient lighting. Making efficient use of daylight costs nothing and burns no fossil fuels.

What accounts for over 70% of the energy used in cities around the world?
  • Streetlights
  • Cars
  • Computers
  • Buildings
Buildings

Correct

Over 70% of the energy used in our cities comes from buildings. That is why building retrofits can make such a huge difference in energy use and savings.

Setting your thermostat two degrees warmer in the summer or two degrees lower in the winter can save how much on your energy use?
  • 1 percent
  • 2 to 5 percent
  • 6 to 10 percent
  • Nothing
2 to 5 percent

Correct

If you change your thermostat’s “set-point” by two degrees, you probably won’t notice the difference, but you could save up to 5% on your utility bills.

Incorrect

If you change your thermostat’s “set-point” by two degrees, you probably won’t notice the difference, but you could save up to 5% on your utility bills.
Which of the following is the most cost-effective energy-saving approach?
  • Making cars more efficient
  • Retrofitting existing buildings
  • Building more efficient buildings
  • None of the above
Retrofitting existing buildings

Correct

Buildings consume more than half of the world’s energy, and 90% of existing buildings will still be standing in 25 years. The most cost-effective way to ensure energy-savings is to upgrade existing buildings.

How long did it take for the Empire State Building to recoup its investment in energy efficiency?
  • 3 years
  • 5 years
  • 10 years
  • More than 20 years
3 years

Correct

It cost just $13 million to integrate energy efficiency into our $550 million Empire State ReBuilding program. We are now saving $4.4 million a year in energy costs. That’s a three-year turn-around on our investment.
