They're far more efficient in terms of energy.

Of course they must be more energy efficient.

Since we don't have to use additional energy, it is very cozy and energy efficient.

like buying energy efficient appliances, putting in efficient lights, turning the lights off occasionally, insulating our homes?

And if you do the energy budget, the data transmission comes for free highly energy efficient.

The grid of tomorrow is no grid, and energy, clean efficient energy, will one day be free.

And so if I run my new energy efficient house forward, compared with the old, non energy efficient house, we make it back in about six years.

This building is also energy efficient, a very small amount of energy is needed to keep the house functioning.

In the same fashion, a more efficient engine that uses less energy will, paradoxically, lead to greater energy use.

Even worse, with our intention of trying to make buildings move towards a net zero energy state, we can't do it just by making mechanical systems more and more efficient.

We should pursue more energy efficient lifestyles, absolutely. How far can we go, though?

So it is better, it is safer it is affordable, it is energy efficient.

Hospitals use two and a half times the amount of energy as office buildings.

This behavior is energy efficient in an environment where calories can be hard to come by.

Until today, I have created an affordable, portable, energy efficient roaster, that produces an excellent result.

I'm efficient.

I'm efficient.

When Efficient

Be efficient.

He's efficient.

Recycling will not solve the problem, as it requires energy, and the process is not 100 efficient.

So very efficient vehicles, buildings and factories save oil and coal, and also natural gas that can displace both of them.

It was for funding from the government for user centered design for energy efficient buildings, difficult to say, and something I had no idea what it was when I went into the workshop, but quickly learned.

They're very efficient.

It's between buildings.

This is the Beddington Zero Energy Development in London, which is one of the greenest buildings in the world.

low cost and affordable for people who work in a first job, assembling something like an iPhone, but make those buildings energy efficient, and make sure that they are safe, so they don't fall down in an earthquake or a hurricane.

Everything is very efficient.

And also a reduction in energy requirements in buildings by an outstanding 15 percent, because you need less fresh air.

And yet that energy and power of architecture has driven an entire social and political space that these buildings occupy.

We are a company in the field of automation, and we'd like to do very lightweight structures because that's energy efficient.

Both buildings burned down.

The two buildings adjoin.

These are my buildings.

We inspected government buildings.

lived in unburned buildings.

And these raised and energy efficient homes were developed by Brad Pitt and Make It Right for the hard hit Ninth Ward.

Efficient machinery replaced manual labor.

But a very efficient reaction.

It is not very efficient.

We run an efficient ship.

Blake It does seem efficient.

So that's actually pretty efficient.

Let's use fuel efficient cars.

It's so much more efficient.
