Energy Conservation: is any behavior that results in the use of less energy. Turning the lights off when you leave the room and recycling aluminum cans are both ways of conserving energy.

Definition of Energy conservation

Page 3: Energy use  Awareness

In its simplest form Energy is the ability to do work

The universe is a combination of the energy and matter

Matter is a substance and energy is the mover of substance

Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes.

What is Energy ?

Cost

Energy prices are rising every year

Why save Energy ?

Climate Change

Change in the earth’s climate causing an increase in temperature known as “Global Warming” Direct cause from Human Activity Global temperature has risen and is on a steep incline unless we take immediate actions to reduce our C02 emissions

Why save Energy ?

“Climate change poses a bigger threat to the planet than terrorism” - The UK government's chief scientific adviser, Sir David King.

Concentrations of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the past 650,000 years.

The rates of increase are absolutely exceptional: the CO2concentration is rising 200 times faster than at any time in the last 650,000 years.

“We do not inherit the earth from our parents, we borrow it from our children” –

Chief Seattle

Behavior Change

Reduce the amount of waste we produce

Change our energy usage behavior to conserve more energy

cycling, and taking public transportation are effective energy saving ideas

Energy efficiency

Improve our technology to improve energy efficiency

Solution

Energy Efficiency is the use of technology that requires less energy to perform the same function. An LED light bulb that uses less energy than an incandescent bulb to produce the same amount of light is an example of energy efficiency. However, the decision to replace an incandescent light bulb with a compact fluorescent is an act of energy conservation

Efficiency vs. Conservation

Efficiency

Energy efficiency involves the use of technology that requires less energy to perform the same function.

Focuses on the equipment or machinery being used

One example is installing LED light bulbs throughout the house

Conservation

Energy conservation includes any behavior that results in the use of less energy.

Focuses on the behavior of people

One example is using day lighting through windows rather than turning on the lights

There are legal obligations the governments around the world have introduced in order to combat the climate change

CRC is a mandatory reporting and pricing scheme to improve energy efficiency in large public and private organizations

ESOS Energy Audits

EU emission trading system puts price o green house gas emissions to create financial incentives for industry and businesses to reduce emissions

Greet Deal lets businesses and other non-domestic organisationspay for some or all of the cost of energy-saving property improvements through savings on their energy bills over time

Global response to climate change

From the energy use chart it can be seen that the two major energy uses are lighting and cooling/heating

In large buildings heating and cooling loads are on on demand and often controlled by Building Management System

New intelligent LED lights can save a huge amount of energy. These lights are controlled by sensors and they dim or switch off when not needed.
