Here are the physics principles that tell you how to reduce the energy consumption of transport.

We're actually measuring its oxygen consumption, its energy consumption.

We must reduce energy demand.

The energy consumption of the United Kingdom, the total energy consumption not just transport, but everything

They had zero impact on energy consumption.

The third demand side option I want to talk about, the third way to reduce energy consumption is read your meters.

Population growth meat consumption dairy consumption energy costs bioenergy production stress on natural resources.

But the total energy consumption will increase to 22 units.

And again, we can measure the reduction in terms of energy consumption.

With this whole sort of suite of policies, we could actually reduce our gasoline consumption or our oil consumption by 20 percent by 2020.

If we could reduce energy use, we wouldn't have to generate electricity anymore.

It's 80 times better in energy consumption, and it's powered by biofuel, by Weetabix.

Now, we'd found a way to reduce its oxygen consumption to rock bottom levels, and it was fine.

I have never been a proponent for nuclear energy. It's because of the consumption, right?

They committed that they're going to take their existing stores and reduce their energy consumption by 20 percent, and their new stores by 30 percent, and do all that in seven years.

What this means is, even if you covered the whole of the United Kingdom with energy crops, you couldn't match today's energy consumption.

Currently, 20 percent of California's energy consumption is used to pump water into mostly Southern California.

If we look at construction and manufacturing, there's major inefficiencies, energy consumption and excessive labor techniques.

The energy consumption of this typical tank here is 80 kilowatt hours per hundred person kilometers.

Reduce Texturing

Reduce detail

Reduce Colors

Reduce To

Now, you can reduce the embodied energy by about 25 percent by using high fly ash concrete.

Reduce Uniform Noise

Reduce JPEG Artifacts

Reduce to Grayscale

Reduce to Monochrome

And you can measure the performance, in terms of energy consumption, of that building against a typical library.

Power Consumption self powered

I want pure consumption.

Consumption and poor quality

No. Um... Consumption, darling.

If we reduce the amount of energy it takes to make the cells, that will become more practical.

So the overall consumption of energy is about 25 watts at takeoff and 16 to 18 watts in flight.

So the overall consumption of energy is about 25 watts at takeoff and 16 to 18 watts in flight.

On the vertical axis, I'm going to show you how many lightbulbs what our energy consumption per person is.

The Hard Path centralized production of energy with continuous consumption and limitless growth or the Soft Path local production of energy, locally owned with resilient and sustainable communities.

Reduce to 256 Color

They reduce pesticide use.

To reduce any anxiety.

On current consumption, that's about 130 percent of domestic consumption for rare earths.

Now the brewers in Montana have already done a lot to reduce their water consumption, but they still use millions of gallons of water.

We deliver personalized home energy reports that show people how their consumption compares to their neighbors in similar sized homes.

Now, if you can take part of the energy content out of doing this, you reduce the system, and you really do start applying biological principles to energy.
