ENERGY SAVING

What can we do?

Hello! Together with you, I want to make a fascinating journey into the world of energy and learn how to save it.

What is energy?

The word “energy” comes from the Greek energeia ( en- 'in' + ergon 'work').

Energy is a physical quantity that characterizes the body's ability to do work.

Such a lot of energy you’ll use until you pull it out!

The development of civilization and the use of energy

The possibilities for conversion and use of energy are an indicator of scientific and technological development.

Forward! Follow the progress!

Law of energy conservation

Not the best way to convert the energy!

The concept of energy connects all natural phenomena.

Energy can not be created from nothing , nor destroyed, it transforms from one form to another.

Some kinds of energy

Any event in the world is connected with the conversion of energy!

Energy is the basis of life on earth

Without energy there is no life ... And with such a life no energy is not enough!

21st Century Challenges

Since the beginning of the last century we have seen an unprecedented increase in world population and the production of energy.

The irreversible contamination of the environment and the impact of "greenhouse effect", causing unacceptable deviation of the Earth's sphere from thermodynamic equilibrium, resulting in floods in some parts of the Earth, and storms and drought in others.

I don’t like such weather

Greenhouse effect and Global warming

Find three differences.

Natural greenhouse effect

The greenhouse effect under the influence of human activities

Choice Options

Humanity faces a choice:

• either follow the way of limiting carbon emissions, which would require certain costs, but will deliver us from ecological disaster

• or leave it as it is and expose to an enormous risk the climate of our planet.

I’m going to the right. Who's with me?

Confronting challenges

1. Rebalancing environment.

2. Search for new opportunities and increased use of sources

alternative energy.

3. Energy saving in all areas of life.

The plan of rebalancing by means of alternative energy!

The use of alternative energy

Zero balance means that the building will produce as much energy from renewable sources, as it consumes.

All buildings in the EU must have a zero energy balance since 2019.

I also have a “zero balance”

Kyoto Protocol

Russian Federation

The Kyoto Protocol obliges a number of countries to reduce or stabilize greenhouse gas emissions in 2008-2012 compared with 1990.

On March 26, 2009 The Kyoto Protocol was ratified by 181 countries, including Russia.

I live in Russia

Countries which have signed and ratified the Protocol.

CO 2 emission

Countries with the largest emission of CO 2 into the atmosphere, millions of tons

CO 2 emission per capita, tons

South Korea

Italy

Great Britain

Canada

Only environmental suit can protect against CO 2

Russia and the Kyoto Protocol

The difference may be sold

Russia joined the Kyoto Protocol in November 2004. Russia produces far less emission than the quota prescribes for the country.

Energy saving is an efficient solution

Windows.

Hot water supply.

Compact fluorescent lamps.

• Energy-saving, gas-filled double glazing, reduces the heat flow by more than 50%.

• Solar water heater with backup electric heater.
• Storage tank with insulation.

• Consume 4-5 times less energy than incandescent bulbs.
• Occupancy sensors automatically shut off lights when the room is empty.

• Silicone foam seal.

Fridge.

• Modern refrigerators consume four times less energy than models of 1974.
• Old refrigerators should be disposed of, but not set to a different location to store extra food. That will allow to fully use the advantages of new energy-saving models.

Have you got anything for me?

Walls.

Stove.

• A thick layer of cellulosic insulation reduces heat loss in winter and summer heat.

• The kitchen equipment is still much to be improved: while using conventional stove food will be transferred only 25% of the heat.

• Conventional ovens can save 20% of electricity.

Dishwasher.

• The auxiliary heater heats the water to the desired temperature, which allows to reduce the temperature of water in the hot water system.
• It consumes approximately 2-3 times less water than required for manual dishwashing.

Law № 261-FZ We are for economy and saving!

Energy saving in Russia

Federal Law № 261-FZ of November 23, 2009. "On

energy saving and energy efficiency improvements

and on Amendments to Certain Legislative

Acts of the Russian Federation. "

The Energy Strategy of Russia

until 2030.

As a result of the implementation

of the Energy Strategy till 2020

energy intensity of GDP in 2008

was 66.1% compared to 2000.

Reasonable decision!

Summary

Energy saving is not only about the economy of money, but also about the care of our planet!

Each of us is a part of the world, so any of our actions or our inaction may influence the course of events!

Energy saving is very important!

Even one cat power can be useful!
