Heating is a third of our energy consumption in Britain, and quite a lot of that is going into homes and other buildings, doing space heating and water heating.

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

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

Heating and hot water supply needs heat energy.

They had zero impact on energy consumption.

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

But the total energy consumption will increase to 22 units.

A lot of heating, frictional heating.

Heating Coil

And you're only getting power from the air that's heating at the same time, but you're wasting energy heating and cooling the metal.

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

Essentially, gas clouds keep colliding, that will inevitably cause some shock heating and energy dissipation.

like heating, cooling etc. and turn them into things that we avoid spending energy on.

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

The heating doesn't work.

Things are heating up.

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

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.

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

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

This heating system burns oil.

This school has no heating.

Next, there's the heating lever.

We're at the heating unit.

The three biggest uses of energy in a store are heating and air conditioning, then lighting, and then refrigeration.

We have a good heating system.

Their rotting corpses heating our atmosphere.

They're heating up the earth's core.

Well, the laws of physics are written up there, which describe how the power consumption for heating is driven by the things you can control.

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.

Because the steam that's heating them has already lost the vast majority of the energy that it's going to give up.

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.

Our dorm's heating system isn't working properly.

Is there central heating in this building?

Is there central heating in this building?

We're just heating up the gaseous water.

So things are really, really heating up.
